Types of Commercial Chillers

Commercial chillers generate chilled water which is used to provide air conditioning in buildings, which is a must-have during the hot, humid North Carolina summers. There are a few different types of chillers, and they can be rated between one to 1,000 tons of cooling energy. Chillers are broken into categories based on how they remove heat from the refrigerant being used to cool the building. Commercial chillers either utilize air, water, or evaporation in order to bring the refrigerant back down to temperature. Here’s a quick overview of the different types of commercial chillers and compressor types each chiller may be designed with:

Air Cooled Chiller
Air cooled chillers are typically used in smaller scale buildings because these systems require a larger ductwork system. Air cooled commercial chillers also tend to be less energy efficient when the point between the base and area served is of a larger distance. Efficiency also decreases if one unit is being used to service multiple areas. They use air to cool their condensers so that the water being used to cool the area is brought back down to the proper temperature.

Water Cooled Chiller
Water Cooled Chillers are usually used in larger buildings and for entire building campuses. They range in size and can even be used to cool large spaces such as airports, shopping malls, and skyscrapers. Water cooled commercial chillers typically utilize cooling towers in order to remove the heat from the refrigerant and bring it back down to temperature.

Evaporative Chiller
Evaporative Chillers work through the process of evaporation to remove heat from a space—water absorbs a large amount of heat to evaporate. In dry climates, evaporative chillers have the added benefit of conditioning the air with more moisture for the comfort of building occupants.

Subcategories of Chillers

Chillers can be divided into different categories based on the compressor type they utilize. The compressor types include: reciprocating, centrifugal, screw-driven, and absorption. The first three types of chillers are mechanical chillers powered by electric motors, steam, or gas turbines. In contrast, an absorption chiller is powered by a heat source, like steam, and it does not use any moving parts.

Reciprocating
Reciprocating compressors use pistons driven by a crankshaft and deliver a small amount of refrigerant at very high pressure. Because of their relatively low price point they were popular in the past, but issues with noise and reliability have made reciprocating chillers less popular. Regular maintenance and upkeep are very important with reciprocating chillers.

Centrifugal
Centrifugal compressors have very few moving parts which makes them a favorite in the industry. They are more energy-efficient than their reciprocating counterparts, and provide a greater flow of refrigerant than a similarly sized centrifugal compressor. They also require less maintenance, although regular inspections should still be scheduled.

Screw-Driven
Screw-Driven Compressors utilize two screws that are fitted together and rotate in order to compress through direct volume reduction. With screw-driven chillers, oil changes, filter replacement, and strainer replacements are required periodically. These also run better with regular visual inspection.

Absorption
An absorption chiller uses a high-energy source, sometimes steam, to boil the refrigerant. In the absorber, refrigerant vapor is absorbed by a lithium bromide solution and condenses into a vapor, releasing the heat it acquired in the evaporator. Because lithium bromide is a salt, if the solution falls below saturation temperature, it can crystallize. In addition to regularly scheduled inspections, a pump teardown and inspection will be required every 5 to 10 years as well as an inspection of the firing rate and safety of direct-fired burners.
