Industry Information

Chillers

Liquid chillers quickly cool large amounts of liquid refrigerant in order to remove heat from the air or other liquids. They then pump cooled liquid or air out as needed.

Industry Uses for Chillers

Many industries use chillers for their daily operations. Here are a few of the key industries which rely on chillers to work efficiently, safely, and effectively.

  • Manufacturing: The manufacturing industry, especially plastics, use industrial grade process chillers to remove heat from processed materials. Without chillers, many forms of production would need to grind to a halt for air cooling.
  • Food and Beverage: Federal law sets strict guidelines for any product intended for human consumption. Secure chillers provide even, reliable cooling systems for products and ingredients which need to be kept cold. Process chillers can flash-freeze tons of product at a time by surrounding products with sudden cold, without affecting moisture or ingredients.
  • Power Generation: The modern world would not be possible without power plants generating electricity for towns and cities around the world. The power supply industry uses process chillers to reduce heat caused by power generation. Without chillers, power plants would not be able to supply the amount of power they do using the amount of space they have.
  • Medicine: Medical equipment and supplies sometimes need low temperatures in order to function. MRI machines and other large medical equipment generate large amounts of heat while they scan patients, and process chillers help to keep these machines from overloading. Liquid chillers are also used for storing medical supplies at low temperatures.

A History of Chillers

Because chillers use the same basic technology as everyday air conditioners, the history of chiller technology starts with the history of air conditioning. In the 1800's, scientists like Benjamin Franklin first began experimenting with ways to use liquid refrigerant to cool liquids and air. These scientists discovered the principles of heat transfer, that they could lower the temperature of air using liquids such as water.

In 1902, Willis Carrier of New England created the first self-contained mechanical air conditioning system. He discovered that heating air reduces relative humidity allowing air to absorb moisture. Cooling the air then pulls heat and moisture from surroundings, reducing both humidity and ambient temperature in a room. This two-phase process of quick heat and quick underlies chilling technology to this day.

After Carrier's invention, research and development in chilling technology developed to meet growing demand. In 1931, scientists discovered that Freon had unique properties allowing it to cool more efficiently than water or air alone. In 1938, Trane introduced the refrigerant-based systems we see in modern-day chillers: compressor, condenser, and evaporator. This enclosed system allowed for the creation of industrial liquid chillers capable of cooling an enclosed space in a brief span of time. In 1950, the plastics industry started using industrial chillers to help meet the demand for quality plastics. This business decision allowed plastics to take center stage as the go-to material for everything from toys to bottling.

Toward the end of the 20th century, other industries began using chiller technology to increase production and improve quality. This would range from glass to power companies. Acting as a silent but necessary partner in the background, chiller technology helped provide the basis for the digital age by making the global electrical grid possible. Today, chillers form a necessary technology in a range of key industries.

The Tech Behind Modern Chillers

Modern liquid chillers use chemical reactions caused by liquid refrigerant moving through a repeated process of heat transfer. Refrigerant and some combination of air or water takes warmth from one medium, carries that warmth away, and then vents excess heat safely into the atmosphere.

In order to perform this cyclic function, chillers need to keep refrigerant securely sealed in pipes and mechanisms designed to withstand heat and pressure. Special refrigerant liquids such as Freon make this process more efficient because they have boiling temperatures lower than boiling water temperature combined with freezing temperatures above freezing water temperature. This narrow range allows for much more efficient chemical reactions leading to faster removal of heat from air or water.

Chiller Parts

Although chiller designs differ in many ways, all chillers have certain key parts in common.

  • Condenser: The condenser takes heated refrigerant and swiftly cools it off in order to return it to a liquid state, starting the cooling cycle. Condensers can be air cooled, water cooled or evaporation cooled.
  • Compressor: At this stage, compression adds extreme pressure to the refrigerant liquid. This step sets the stage for the refrigerant to absorb heat. The type of compressor will vary by chiller. For example, screw chillers use twin rotary screws to achieve compression. Screw compression allows for high-speed continuous use with more even flow than other motorized compression types.
  • Evaporator: This part of the system cools liquid by taking highly-pressurized refrigerant as it cools. The chemical reaction results in extremely low temperatures which absorb heat from the liquid to be cooled.
  • Refrigerant: Refrigerant varies by chiller type, with some chillers including a mix of different chemicals. Because of environmental concerns, refrigerant of all types tends to be highly regulated. A given chiller must be rated to use with a certain refrigerant type in order to minimize refrigerant leakage. Over time, chiller service can include replacing or topping off refrigerant.
  • Expansion Valve: The expansion valve controls the flow of refrigerant into the system by sensing the actual and desired temperature. In industrial grade chillers, expansion valves can help create a chain reaction by adding more refrigerant as refrigerant starts to cool. As refrigerant goes through the standard chemical reactions, the valve pulls in more refrigerant to pull heat from refrigerant already released, create even more rapid cooling.
  • Vents and/or Cooling Towers: All air conditioning requires venting of excess heat. Due to a high volume of liquid usually measured in tons, industrial chillers often require external cooling towers to control heat.

Industrial Chiller Types

There are several types of liquid chiller available. Depending on business needs, each type has benefits and downsides.

  • Vapor Compressor: This chiller type follows a more conventional approach. Vapor compressor refers to the use of a standard mechanical compressor to vaporize liquid refrigerant for cooling purposes. High volumes of refrigerant move from the evaporator to the compressor and condenser. For smaller operations or where storing tons of coolant would not be practical, vapor compressors allow for quick cooling of large amounts of material.
  • Absorption: This chiller type uses heat from combustion or hot water in place of electricity. Although absorption chillers use the same basic cycle of evaporator, compressor, condenser, the compression process uses a chemical solution instead of mechanical compression. At the compressor stage, chilled water enters the system to absorb heat in a heat exchanger. Refrigerant is diluted using a chemical solution and passed through the heat exchanger before proceeding on to the next stage in the cycle. The cold water then exists the system. Heated water or combustible material like gasoline then enters the system generator at the condenser stage. Industrial chillers of this type often need large cooling towers in order to hold water.
  • Water Chiller: Water chiller refers to chillers used to create large amounts of cold water and to keep water cool. While following the familiar cycle of evaporator, compressor, and condenser, these chillers cool water instead of air, pumping water out into an external system of pipes. These systems need to be carefully tailored to fit inside of existing structures.
  • Process Chiller: This chiller type refers to the amount of work these industrial chillers perform, and they are generally of the absorption type. Process chillers usually require substantial space, because they allow tons of refrigerant to cycle through at any given time. These chillers have the familiar cycle of evaporator, compressor, and condenser together with a metering device to control refrigerant levels. However, these parts are almost always high-quality stainless steel. In order to process tons of refrigerant at a time, industrial-grade evaporators, compressors, and condensers must be able to stand up to high pressures.

Benefits of Using Chillers

While it may be possible to run some operations with or without liquid chillers, this machinery offers clear benefits.

  • Faster Cooling: The main purpose of industrial chillers is to cool large amount of material fast, and they do this better than any other type of equipment.
  • Better Use of Space: Compared to other forms of cooling such as ice or chemicals like nitrogen, chillers take up less room and use that space more efficiently. Industrial chillers let businesses dedicate a set space for machinery. They keep things reliably cool, so that way owners can focus on the rest of their operations.
  • Predictable Cooling: Where other cooling methods may cool some areas more than others, careful use of industrial chillers lets you keep temperatures even in a given area. Uneven temperatures could lead to product damage and product loss.
  • Cost Savings: Chillers can save money compared with alternate forms of keeping materials cool.

How to Use Chillers

When it comes to making the most of a chiller, this tends to depend on individual industry. For example, manufacturing facilities continue to have the foremost need for this technology, using process chillers to keep machinery cool. In order to make use of process chillers, owners need to take a number of factors into account. First, they need the right chiller for the factory floor, given space and power supply options. Then, they need to look at manufacturing schedule. This will shape how and when they use the chiller. As a general rule, chillers remain on only when needed. In some uses, for example water chillers used to supply water for a building, this may mean finding a chiller that can stay on constantly.

How to Custom Design Chillers

There are always some aspects of chiller technology unique to individual business requirements. As with any large equipment, space considerations will be a major concern. If machinery hooks up to pipes in order to keep water cool or regulate temperature in a room, then design requirements will need to consider the system as a whole. Volume of coolant, power source, size of the chiller as well as compressor and evaporator types can all be customized to fit individuals needs.

When designing a custom chiller, business should always plan for the future. Smaller, modular liquid chillers let owners move systems as needed, adding additional parts as business grows or changes. Larger, stationary models provide plenty of cooling power that can turn on and off as needed. The ideal custom system will mean consider all options in terms of the needs of the present and the possibilities for years to come.

Safety and Compliance Concerns

In many cases, local and federal laws regulate the use of chilling technology. Food, beverages, and medicine must be kept safe for human consumption. Uneven cooling can result in contamination and product loss in many different industries, including plastic manufacturing. In addition to these concerns, refrigerant leakage can lead to health and environmental dangers. For this reason, government regulations usually limit chiller service and maintenance to licensed professionals with equipment designed to safely and securely handle liquid refrigerant.

When installing a chiller system, there are a number of important considerations. Foremost is cooling capacity. Industrial chillers are measured by their cooling capacity in terms of tons, each ton being roughly equivalent to the heat of fusion of one ton of ice, or 12,000 Btu/h. Capacities range from portable chillers with fractions of a ton to permanent multi-unit “plants” with cooling capacities of thousands of tons. Another significant decision is the sort of refrigerant; this will mostly depend on the range of temperatures the chiller will face. Common refrigerant choices include water, ammonia, carbon dioxide, sulfur dioxide, alcohol, brine and methane. Fluorocarbons, especially chlorofluorocarbons (CFCs) have also been used widely as refrigerants, but they are decreasingly common because of their ozone depletion effects. Other specifications to look at include condenser and evaporator flow rates, power source, cooling capacity, efficiency, location, compressor type and compressor horsepower. Most chillers also come with a local and/or remote control panel with temperature and pressure indicators and emergency alarms. When configured properly, chillers can provide simple and effective solutions for many process cooling and industrial air conditioning applications.

Improve Your Bottom Line with a Chiller Upgrade

One of the biggest expenses in any factory or manufacturing capacity is the expense of a chiller. Keeping things cool is expensive and requires a high level of energy. New innovations are made every year in the technology and energy-efficiency of chilling equipment on the consumer and industrial level.

But did you know how much more cost-effective new chillers are than old chillers? One company in San Francisco was able to save over $1.3 million dollars each year once they switched to a new chilling system. This company switched out old absorption chillers for new energy-efficient electric chillers. The company also upgraded the chilled water distribution system. The addition of the new system also saved over $100,000 in maintenance costs each year and the company was able to recover the cost of the system in fewer than 6 years.

Generally, when a company upgrades their chilling system, it is down out of necessity and the goal is to save as much during installation as possible. However, a shortsighted view like that can actually cost a company big money in the long run. By considering the long-term, this company was able to take funds traditionally spent on their utilities and use them for upgrades in other aspects of the business to increase profits. One simple move of upgrading the chiller system enabled the company to benefit as a whole on multiple levels.

The idea of spending money now to save money later is not a new idea, but few companies actually implement this idea. However, as the San Francisco company shows, upgrading one system can actually have a positive impact on the company as a whole and increase profits permanently.

COP is calculated by dividing a system’s cooling ability by the system’s heat input and is expressed in BTU/hr.
 
Compressor – A device that increases pressure on a gas through the act of pumping. Compressors are responsible for the compaction of the vaporized refrigerant to a pressure level suitable for liquification, which occurs in the condenser.

Condenser – A device that removes heat via forced air, water coil, etc., in order to convert a high pressure gas into a lower pressure liquid. Condensers remove heat from the compressed vaporized refrigerant, at which point, the refrigerant returns to a liquid state.

Control Center – The central part of a refrigeration system in which the system is operated and maintained.
 
Coolant – A liquid used to remove heat.
 
Energy Efficiency Rating (EER) – Indicates the efficiency of an air conditioner or cooling system by comparing the amount of energy needed to produce cooling with the quality of the system’s cooling ability and is calculated by dividing the system’s BTU by its wattage. For example, if a cooling system maintains 20,000 BTUs and uses 1,500 watts, the system’s energy efficient rating would equal 13.3.
