Chapter 1: What is an Industrial Air Conditioner?
An industrial air conditioner is a large-scale air conditioner that is designed for cooling warehouses and industrial facilities. Although the cooling method for industrial air conditioners is similar to that used by residential air conditioners, industrial air conditioners have greater cooling capacity with the capability of providing stable temperatures over a wider area. Unlike residential air conditioners, industrial air conditioners have multiple compressors, evaporators, expansive ducting systems, fans, controllers, and complex filtration units.
While the work of a traditional air conditioner is to create a comfortable atmosphere, industrial air conditioners provide control temperatures for sensitive materials, perform specialized industrial operations, and ensure proper equipment operation. Industrial environments require precision temperature and humidity control using highly advanced filtration systems. All of the components for an industrial air conditioning system can be contained in a single packaged unit or in separate units, depending on the system’s design. Residential air conditioners are designed to cool a specified number of square feet while industrial air conditioners regulate temperatures in several areas or zones for extended periods of time.

Components of an industrial air conditioning system are the same as those for any other form of air conditioning unit. The main difference between the systems is the size, durability, and strength of industrial air conditioning components, which are designed for endurance and stability. The function of an industrial air conditioning system is to control the temperature, humidity, and air quality in a large area, which can be over several thousand square feet.
Chapter 2: Types of Industrial Air Conditioners
As with all types of industrial machinery, industrial air conditioners are designed to fit the conditions for which they are used and come in various sizes to accommodate application requirements. A major part of the differentiation between industrial air conditions is their size, which range from floor models to huge systems that cover the tops of buildings. Different industrial operations, that vary in size, require air conditioners that perfectly match their requirements.
The physical size of an air condition unit is not the metric used to determine its capacity. The critical statistic is an air conditioner’s ability to remove heat, which is measured in British thermal units or BTUs. A one-ton air conditioner can remove 12,000 BTUs of heat per hour. When shopping for an industrial air conditioner, it is important to know the cooling load of a structure, the amount of heat that has to be removed.
The correct size of an industrial air conditioner is critical. An undersized industrial air conditioner, which may be less expensive, will overwork, increase energy costs, and quickly fail. This may lead to the assumption that a larger air conditioner at a higher cost will be the solution. An oversized industrial air conditioner will have temperature swings, inconsistency, hot and cold spots, produce high humidity, and increased energy costs due to the unit constantly turning on and off.
It is essential, when shopping for an industrial air conditioner, to work with an industrial air conditioner professional who uses metrics and calculations to determine the type of unit that best fits an environment. Professionals consider various factors to calculate the best type of unit. The height of the ceiling, materials being handled, and equipment operation all influence the cooling load. Each aspect and detail are measured, examined, and studied in order to provide the perfect industrial air conditioning solution.
Although physical measurements are necessary, products, processes, and procedures are considered during the selection process. Stable temperatures for such factors are necessary to ensure worker safety and the quality of products. Industrial air conditioner manufacturers work closely with their clients to develop custom air conditioning solutions that fit manufacturing and product requirements.
Air conditioning is an expected and accepted part of modern society. Large and small stores, office buildings, cafes, and coffee shops have air conditioning for the comfort of customers and employees. To meet the many and varied requirements of air conditioning, a wide variety of heating and cooling units of varied capacity have become necessary. The most common types are central air, ductless and mini split, multi split, VRF (variable refrigerant flow) and VRV (variable refrigerant volume), and chillers. Although the term industrial air conditioner can be used for commercial systems, the acronym HVAC, which stands for heating, ventilation, and air conditioning, refers to a highly expansive system that includes an industrial air conditioner and some form of heater, such as a boiler or furnace.
Central Air Conditioning
Central air conditioning systems circulate air and exchange heat to cool or heat rooms to temperatures set by unit controls. Warm air is removed from a room and replaced by cool air. A supply and return ducting system circulates air through the system. Central air conditioning systems are a common component of large facilities.
Although the components of an industrial central air conditioning system may be the same as that of a residential system, the tonnage of the systems radically vary. The obvious physical difference between the systems is further emphasized by the tonnage of cool air being delivered. A normal residential central air conditioner delivers 5 to 8 tons of cooling, which is sufficient for a normal, family size home. By comparison, an industrial air conditioning system delivers over 50 tons of cool air and consumes substantial amounts of energy.
The choice of central industrial air conditioners is due to their efficient distribution of air. They are out of the way, perform quietly, and have convenient interfaces. The term industrial air conditioning system covers different types of systems that include split, packaged, and VRF and VRV systems. The system that is chosen for a facility is determined by the industrial air conditioning manufacturer or their representative using a set of established criteria and metrics.

Split Central Air Conditioning System
A split central air conditioning system refers to a system where an outdoor unit is paired with an indoor unit. The pairing of the units provides optimal efficiency and energy savings. In addition, the design allows for aesthetic adjustments. Unlike larger industrial central air conditioning systems, split systems are designed for single rooms that require focused air temperature control for special and unique conditions.
Of the various types of industrial air conditioning systems, split systems are the most basic and are somewhat like residential systems. Referred to as ducted split systems, the outdoor unit consists of a compressor and condenser coil, which turn refrigerant gasses into a cold liquid. The inside unit houses the blower that pushes the cooled air through the ductwork into the building.
Although the duct form of split central air conditioner systems is common, duct free systems are also used. Unlike a duct system, a duct free or ductless system has blowers that spread the cold air. In many ways, they are similar to having individual air conditioners in each room. The absence of ducting decreases the amount of necessary maintenance since there aren’t any ducts for dust and dirt build up. They are commonly used in buildings that have areas that are not used all the time.
Split central air conditioning systems are unlike packaged systems that have all the components in a housing. Split units allow for a certain amount of flexibility and can be cost saving. The connection between the indoor and outdoor units consists of piping and wiring.

Packaged Central Air Conditioning System
Packaged central air conditioning systems are standard duct systems with all components contained in one large unit. They function the same as traditional air conditioners but are larger, more robust, complex, and durable. Referred to as RTUs or roof top units, packaged industrial air conditioning systems are located on the roof of a facility. Cool air runs through the ducting system to every part of a building.
The use of packaged central air conditioning systems is ideal for large locations with a lot of space. Being outside the building ensures that the operation of the system will not produce noise that will interfere with business operations. Controls, electrical wiring, and evaporator coils are packaged and protected in a single unit.
Packaged central air conditioning systems are designed to provide cooled air to several story buildings and come in a wide range of configurations. They are huge units that require heavy equipment for installation and are connected to ductwork. The housing for packaged central air conditioning units is tightly sealed to protect against the elements. Access panels are located near critical areas for repairs and maintenance purposes. The condenser for packaged air conditioning units can be air or water cooled.
Each of the parts of a packaged industrial central air conditioning unit is larger, stronger, and more durable than the components of a residential air conditioner. Although their function is the same, they are able to endure more stress due to the long hours they are in operation. Depending on the size of the building they are cooling, packaged industrial air conditioners are capable of several tons of cooling.

Variable Refrigerant Flow (VRF) and Variable Refrigerant Volume (VRV) Industrial Air Conditioners
VRF and VRV industrial air conditioning systems are multi-split air conditioning units that use variable speed compressors to regulate the flow of refrigerant between the condensing unit and the coil air handling unit. The anagrams used for VRF and VRV industrial air conditioners are terms that describe the same air conditioning technology.
A highly advanced form of air conditioning technology, VRF systems are based on a set of basic principles. Refrigerant is the only coolant material and does not include chilled water. The inverter compressors in the system make it possible to lower power consumption. Like other forms of split air conditioner systems, several air handling units are an essential part of the system. The design of VRF systems makes it possible to expand the system as the needs of a project demand.
The outdoor unit for a VRF system consists of one or more compressors, which are connected to several indoor units. Refrigerant piping runs from the outdoor units to the indoor units, a design that is common to split air conditioning systems. Control of the system is possible at each indoor unit and consists of communication wiring, a two-wire cable that runs from the outdoor unit to the interior units creating a closed loop network. Each indoor unit has a control panel that can have a wireless remote.
The system receives input requesting a desired temperature. The unit measures the ambient outside temperature and the selected temperature. It uses its logic system to reach the desired temperature using optimal power consumption. The condenser is activated at the exact level necessary to meet the indoor requirements. As each indoor unit is activated, the system repeats the process to meet the demand. The system constantly changes and adjusts as new requests are made.
The three types of VRF systems are cooling only, heat pump, and heat recovery. VRF systems are a ductless system. The key to the systems is their inverter compressor, which allows the compressor to ramp up or down depending on user requirements. Such compressors are able to adjust their motor speed to deliver varying cooling capacities. This is unlike a typical compressor that operates at a fixed speed. Although the variations in compressor speed may seem inefficient, in actuality, it is an energy saving method.
Inverter compressors are always on, running at a rate that is a fraction of their full speed. The design makes it possible to maintain consistent temperatures compared to a reciprocating compressor. In addition, inverter compressors are more durable and experience less wear and tear. Their low CO2 and CFC emissions make inverter compressors eco friendly.

VRF systems operate without chillers or coils and are quick, highly responsive, and adaptable. The commercial use of VRF systems is due to their high efficiency for heating and cooling. As with most technological advancements, VRF systems have a high upfront cost that can be amortized over several years of lower energy use. A portion of the higher cost is due to the customization of each room of a facility.

Chillers
The different types of chillers offer a unique cooling system that removes heat using water that circulates through a building. As the water or some other liquid circulates, it absorbs heat. When the water returns to the chiller, the heat is transferred from the water to the ambient air. The process of chillers is used for industrial functions far beyond air conditioning and includes a wide variety of manufacturing processes.
The many types of chillers have their own characteristics, functions, properties, and performance traits. Included in the list of chillers are centrifugal, modular, water-cooled screw, air cooled screw, air cooled scroll, and absorption. The different types of chillers are designed to meet the needs of industrial functions. Although chillers are not referred to as air conditioners, they have the same components including an evaporator, compressor, condenser, and expansion valve or unit. In addition, chillers rely on refrigerant for absorbing and transferring heat.
-
Air Cooled Chiller – Air cooled chillers are used in buildings with ductwork and are a packaged unit. They use refrigeration to cool fluids or dehumidify air and do not have cooling towers. The heat collected by the circulating air is released into the atmosphere. The design of the process necessitates that an air cooled chiller have access to an external source of air. The fluid or liquid that collects heat from a building can take several forms including water. Since air cooled chillers require ductwork, they are installed in small buildings.
-
Water Cooled Chiller – With a water cooled chiller, water is piped through a building to air handling units with their own ductwork. Since the movement of chiller water is the basis of a water chiller system, ductwork is not necessary as a delivery method. In addition to the typical components of an air conditioner, water cooled chillers have a cooling tower. The refrigerant cools the water that is cycled through the chiller and is pumped out to the sections of a building.
As with an air cooled system, water collects heat from a building and replaces it with cooled air. It is in the cooling tower that the collected heat is released. Water cooled chillers are smaller, take up less space, and are highly efficient. Unlike air cooled chillers, water cooled chillers can be installed indoors, which reduces maintenance costs and increases their longevity. In addition, water cooled chillers have a higher bubble temperature, since wet bubbles have a lower temperature than dry bubbles.

Chapter 3: The Difference Between Industrial and Residential Air Conditioning Systems
Although industrial air conditioners and residential air conditioners have similar components, they are different in the nature of the processes they use. Both systems supply cool air at a preselected temperature to match the comfort needs of the occupants. The major factor that sets them apart is the shear capacity of industrial air conditioners, which is far beyond that of a residential air conditioner.
Residential air conditioners are designed to make a living space comfortable and livable. If the system fails, the level of comfort goes down and various adjustments have to be made. When an industrial air conditioning system fails, there can be catastrophic results that include the safety of workers, loss of production goals, and other economic factors that can ruin a business.
Size
The most obvious differentiating factor is the size of an industrial air conditioner compared to a residential air conditioner. Air conditioners for homes are chosen based on room size and the design of a home. Industrial air conditioners are configured in accordance with heat load, which depends on the air to be cooled, number of occupants, positioning, shade, and window coverings. In addition, heat generated by computers, lighting, equipment, and machinery are factored in and are calculated using a heat load equation.
The larger units of industrial air conditioners require complex maintenance procedures. Since residential air conditioners are smaller without large housings, they allow for easy access while industrial air conditioners, especially packaged units, have huge enclosures with several access panels.
A normal residential air conditioner delivers 8 to 10 tons of cooling capacity. In contrast, an industrial air conditioning system delivers more than 50 tons of cooling, on average. The differences in capacity impact the amount of power required to operate the systems and their functional costs. As the required capacity rises, electrical consumption increases.
Usage
As with all forms of industrial equipment, industrial air conditions are hard working machines that operate constantly over extended periods of time. A typical industrial air conditioner operates 10 hours per day or more while residential air conditioners operate approximately 6 hours per day or less. In many cases, industrial air conditioners operate 24 hours per day. The greater usage places stress on the system requiring more durable components.
Unit Types
There is a wide range of industrial units that includes customized units for unique conditions. The range of industrial air conditioners vary from roof top central air conditioning systems to split systems and systems with cooling towers. The smaller units of residential air conditioners include wall units, room air conditioners, and single unit central systems. In all cases, the types of units used for industrial air conditioning are larger and more robust.

Complexity
The controls for residential air conditioners are designed to meet the static requirements of a living space. Industrial air conditioning units are more complex to meet the higher needs of a workplace environment. Systems can be divided into different departments, offices, and work spaces with different air flow requirements. Buildings and factories have thermostats placed in various locations to meet the needs of products, personnel, and equipment.
The complexity of industrial air conditioners is driven by the varying needs of users and is the reason that industrial air conditioners have a modular design. The single unit structure of industrial air conditioners simplifies maintenance and enables upgrades.
The components of a residential system are predetermined and split between indoor and outdoor units. The capacity is preset and is expected to remain constant. Any changes or modifications are arduous and require extreme adjustments.
Equipment Placement
Residential air conditioners, aside from the interior wall and window types, are placed in an area around a house. Industrial air conditioners are placed next to a building or on its roof. The factors that determine placement are saving space, avoiding noise pollution, and ease of maintenance, since industrial air conditioners require regular, scheduled maintenance. With industrial air conditioners, the goal is to have them out of the way of the public and personnel.
Unlike residential air conditioners, the positioning of an industrial air conditioner is carefully considered due to the value of space at an industrial complex. Placing units out of the way and inaccessible avoids the risk of interference from unknown sources. Service repairs can be handled discreetly and out of site.
Customization
During home construction, the same brand, capacity, and configuration of air conditioning units can be used for every home in a subdivision or on a street. Once the square footage is known, one unit can be chosen and installed in all homes. The uniqueness of every industrial location requires the development of a customized air conditioning system for every location. Each system is complex and designed for efficient performance.
Humidity and temperature requirements for residential air conditioners are fairly standard and unchanging. Industrial air conditioners closely examine these variables as a part of the initial evaluation and selection of a system. Control systems are designed to be set to accommodate fluctuations and changes that are not a concern for residential air conditioners. The variations in the controls of an industrial air conditioning system are designed to meet the needs of the environment. Residential air conditioning systems can have optional accessories added, a factor that is not part of industrial air conditioning design.
Drainage
As would be expected, the drainage system for an industrial air conditioner involves a complex set of pipes and pans that are designed for efficient removal of water. The goal of the drainage system is to avoid clogs or blockage that could cause overflow and create maintenance issues. With both types of air conditioners, the removal of excess water is a necessity. Again, the size of an industrial air conditioning system requires more preparation for drainage due to the capacity of the system.
Maintenance
Another obvious factor related to industrial air conditioners is their maintenance, which is on a regular schedule, which can be monthly, daily, or weekly, depending on the workload of an industrial air conditioning system. With industrial and commercial facilities, maintenance is crucial to ensure uninterrupted service. As every industrial air conditioner manufacturer knows, neglecting maintenance can lead to increased costs and operational shut downs.
The maintenance costs for complex industrial air conditioners are very high due to the complexity of components, the size of systems, and the uniqueness of equipment mechanisms. Industrial air conditioner manufacturers provide maintenance personnel to assist their customers in maintaining equipment and ensuring optimal performance. A part of the service is regular updates regarding part replacement, operational factors, and other issues related to proper equipment operation.
The simplicity of residential air conditioners ensures continual peak performance without interruption. Most residential units run for several years without needing repair. Wise homeowners request regular checkups for peace of mind.
Summary
In every aspect of the comparison between industrial and residential air conditioners, size is the main factor. While most residential air conditioners cool a home of a few thousand feet, industrial air conditioners are required to maintain stable temperatures for locations of several thousand feet and multiple stories. Such environments necessitate dynamic and powerful equipment that can endure the stress and wear required. Unlike residential air conditioners that seldom face any stress, industrial air conditioners are built of sturdy materials designed for endurance and are supported by manufacturers who back and support their products.
Chapter 4: How to Choose an Industrial Air Conditioner
The selection of an industrial air conditioner begins with the system’s manufacturer or manufacturer’s representative that provides service and support during the selection process. It is essential and important that the process begin with the expertise and knowledge of manufacturers and service providers. Manufacturers have a team of experts dedicated to guiding their customers to the perfect system that meets a customer’s requirements.
Unlike the installation of a residential air conditioner, there are several parameters that have to be examined in the selection of an industrial air conditioner, which are far beyond the square feet of a facility or its location. At the center of the process is the collection of data that describes a location and its purpose.
To ensure the proper performance of an industrial air conditioner, it must be the correct size. The calculations necessary to make that determination takes time, study, research, and investigation. Although the process is time consuming, the benefits lead to comfort and lower operating costs.
The size of industrial or commercial air conditioners is rated in tons that increase in increments of a half-ton. A one-ton air conditioner removes 12,000 BTUs of heat per hour. As all air conditioning experts know, cooling is the removal of heat. The calculations for determining the right industrial air conditioner for a location is partly related to the measure of a location's cooling load, the amount of heat a cooling system must remove. There are numerous factors that affect the cooling load, some of which are structural design, exposure to sunlight, occupants, machinery, and processes.
Cooling loads are divided into external and internal. The external aspect of the cooling load refers to the weather conditions of a location. The external load for Arizona is drastically different from the cooling load of Michigan or Minnesota that have weather conditions that bring heat and cold. The external load is also influenced by the design of a structure and its insulation.
The internal load includes the people, equipment, lighting, windows, air circulation, and various other factors that professionals assess. Each aspect has an influence on the cooling load and the required air conditioner tonnage.
As with residential air conditioning, the calculations for an industrial air conditioner begin with the square footage of the space. In many industrial locations, the height of the ceiling exceeds the traditional eight-foot ceiling of residential properties and offices. The height of ceilings is one of the reasons that industrial air conditioners have to be so powerful in order to accommodate the vacant space.
The initial calculations for an industrial air conditioner begin by dividing the square footage by 500 and multiplying the answer by 12,000, the number of BTUs. Each person that works in a space requires the addition of an additional 380 BTUs per person. Each window is worth 1000 BTUs.
Using this method of calculating, a 5000 square foot space with four workers and three windows would require an air conditioning system of approximately 124,520 BTUs. Since the size of air conditioning systems is measured in tons, the 124,520 BTUs would need to be divided by 12,000 to determine the tonnage of the system. In this example, the tonnage would be between 8 and 10.
As is indicated by the mathematical calculations, it is essential to consult with an industrial air conditioning professional when shopping for an air conditioning system. There is a great deal of difference between installing a residential air conditioner and an industrial one. The expense of the process necessitates the involvement of professionals who understand the challenges of cooling large spaces.
The Air Conditioning Contractors of America provide manuals, guidelines, and literature that detail sizing methods and system designs. Included in their literature are four considerations for industrial air conditioner installation.
- Application – Application refers to the industry and location that will be cooled. Machine shops and metal processing facilities require more robust air conditioning compared to an office building.
- Structure – The structure refers to the size and type of building, such as single story, multiple stories, warehouses, or other types.
- Square Footage
- Air Conditioning System Type – The system type refers to the power source, gas or electricity, and type of air conditioning system, air or water cooled.
The careful selection of an industrial air conditioner is a critical decision. The installation of a system that is too small will cause the system to overwork, place stress on components, and require costly repairs. On the other side, the installation of a system that is too large can lead to 1poor air quality, excess humidity, discomfort, and increased costs. Only a trained industrial air conditioning specialist can provide the data, consultation, and guidance to ensure a successful air conditioning choice.
Chapter 5: Components of a Commercial and Industrial Air Conditioner
The high-quality performance of an industrial air conditioner requires that all the parts and components of a system work together. A general knowledge of the components can help in assessing malfunctions in a system and prevent larger issues. Although many of the components of an industrial air conditioner are the same as those of residential air conditioners, the complexity and intricacy of industrial air conditioners requires components to be robust, highly durable, and long lasting.
Compressor
The compressor is the heart of an industrial air conditioner. It circulates the refrigerant between the condenser coils and the evaporator. Compressors change the refrigerant from a gas to a liquid before it enters the condenser coil. It compresses the refrigerant to turn it into a high-pressure gas.

Control Panel
The control panel determines the temperature for each zone or section of a structure. It is usually set by maintenance personnel and closely monitored. Fluctuations in zones are detected by the control panel, which activates the system to increase or decrease cooling. The size of the control panels varies and can include several high-performance sections with complex technological controls or be a single touch screen control. The variations in the size of control panels are due to the different types of industrial air conditioners that are custom designed to fit the requirements of a location.
Industrial air conditioning control systems may have direct digital controls (DDC) for improved energy efficiency. DDCs have sensors that monitor temperatures. Systems provide system updates, detect problems, and request maintenance. Although a DDC system is expensive, it can be cost effective in the long run. Regardless of the type of controls, simple or DDC, they help realize energy savings of 5% up to 20%.

Condenser
Industrial condensers condense the refrigerant back to a liquid. They transfer the heat from the refrigerant as it is changed to a liquid phase. The type of application for which the condenser is used determines the type of condenser since different applications require the handling of different pressures and levels of temperature. The cooling process for condensers can be air or water depending on the air conditioning system design.

Thermal Expansion Valve (TXV)
The thermal expansion valve controls the amount of refrigerant that enters the evaporator. It regulates the heat of the refrigerant. In the condenser, refrigerant is condensed to a high-pressure liquid by removing heat from it and transferring it into the environment. As the refrigerant moves from the condenser to the evaporator, it is restricted by the expansion valve that reduces the pressure and allows isenthalpic, a process where the liquid expands but retains its level of heat, back to the vapor phase for absorbing heat.
The sensing bulb of the thermal expansion valve is connected to the output of the evaporator and senses the temperature of the refrigerant leaving the evaporator. The gas pressure in the sensing bulb provides the force for opening the TXV, which adjusts the flow of refrigerant into the evaporator.

Evaporator
From the expansion valve, the refrigerant enters the evaporator at low pressure. In the evaporator, the refrigerant goes from a low-pressure liquid to a low-pressure gas, which allows the refrigerant to absorb heat. As air passes through the evaporator, it gets cooler and loses its heat. The cooled air is pushed out into the facility by ductwork or an air handler. After absorbing heat, the refrigerant returns to the compressor and the air conditioning cycle begins again.

Ductwork
The ductwork of an industrial air conditioning system delivers and removes air. The many forms of ductwork include round or rectangular, metal or fabric. Metal round or rectangular ductwork is used the most with industrial air conditioners due to their ability to fit in limited space and their high durability. They allow for even and controlled air flow, ensuring efficient system operation.
Round ductwork allows air to move smoothly due to its ability to transition for varying degrees of angles. In addition, unlike rectangular ductwork, round ductwork has less friction and turbulence, which further enhances airflow. Since round ductwork can move higher volumes of air, it has lower energy costs.

Air Filter
A common addition to industrial air conditioners is an air filter that cleans the air and removes particulate matter. Depending on the level of air quality required by a facility, the air filter may be a high efficiency particulate air (HEPA) filter, which removes the smallest of contaminants. Although the primary role of filters is to clean the air, they also keep a system clean and free of large particles that can interfere with a systems operation.
Aside from HEPA filters, the other types of filters include large pleated filters and fiberglass filters. UV filters are a special type of filter that captures airborne viruses and bacteria using ultraviolet light. They are not effective at capturing dust, dirt, and particles.

How an Industrial Air Conditioning Works
Most industrial air conditioning systems operate like a residential system but are larger and more dynamic. In the simplest form, the compressor compresses the refrigerant, increasing its pressure and temperature. From the compressor, the refrigerant moves to the condenser, which liquifies it. Before entering the evaporator, the expansion valve lowers the pressure of the liquid and cools it before releasing it into the evaporator that transforms the refrigerant cool liquid into a warm gas.
The above description is the basics of an air conditioning system. Other features may be added for extracting heat or cooling the refrigerant. An industrial air conditioner may be part of an interconnected system that involves a furnace, heater, and air handler. As with all aspects of industrial air conditioners, the addition of components depends on the system's design.
