How Chillers Work
In most process cooling applications, how chillers work is that a pumping system is used to circulate cool water or a water/glycol solution from the chiller to the process. The cool liquid eliminates heat from the process and the warm fluid goes back to the chiller. The process water helps heat transfer from the process to the chiller.
Process chillers host a chemical compound called a refrigerant. Depending on the required temperatures, there are many types of refrigerant and applications, but they all work on the same principle of compression and phase-change of the refrigerant from a liquid to a gas and back to a liquid. This method of heating and cooling the refrigerant and changing it from a gas to a liquid and back again is what’s known as the refrigeration cycle.
The refrigeration cycle begins with a low-pressure liquid/gas mix entering the evaporator. Inside, heat from the process water or water/glycol solution boils the refrigerant, which alters it from a low-pressure liquid to a low-pressure gas. The low-pressure gas enters the compressor where it is compacted to high-pressure gas. The high-pressure gas enters the condenser where ambient air or condenser water subtracts heat to cool it to a high-pressure liquid. The high-pressure liquid then goes to the expansion valve, which controls how much liquid refrigerant enters the evaporator, ultimately beginning the refrigeration cycle all over again.
Types of Commercial Chillers
Commercial chillers generate chilled water which is used to provide air conditioning in buildings. 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:
