Compression: The compressor is the core component of the water chiller, which is equivalent to the "heart" of the system. It sucks in the low - pressure and low - temperature refrigerant vapor from the evaporator. Then, through mechanical compression, it increases the pressure and temperature of the refrigerant, and discharges it into the condenser as high - pressure and high - temperature vapor. This process requires the input of mechanical energy, which is usually provided by an electric motor.

Condensation: The condenser is a heat exchanger. The high - pressure and high - temperature refrigerant vapor enters the condenser, and exchanges heat with the external cooling medium (air in air - cooled chillers or cooling water in water - cooled chillers). Due to the temperature difference, the refrigerant releases heat to the outside, and gradually condenses into a high - pressure and normal - temperature liquid state. At this time, the heat absorbed by the refrigerant in the evaporator and the heat generated during the compression process are both released.

Expansion: The high - pressure and normal - temperature liquid refrigerant flows through the expansion valve (or other throttling devices). The expansion valve reduces the pressure and temperature of the refrigerant, and makes part of the refrigerant vaporize, so that the refrigerant becomes a low - pressure and low - temperature wet vapor and enters the evaporator. The expansion valve can also precisely regulate the flow of the refrigerant to ensure the stable operation of the system.

Evaporation: The evaporator is the low - pressure side of the system. The low - pressure and low - temperature wet vapor refrigerant absorbs a large amount of heat from the chilled water or other cooled objects in the evaporator, and vaporizes into a low - pressure vapor. This process cools the chilled water or other cooled objects, meeting the cooling requirements. The vaporized refrigerant is then sucked in by the compressor again, starting the next refrigeration cycle.

Can a chiller be used without a storage tank? In most cases, using a storage tank can reduce the required size of the chiller and the peak electrical load. Since the water is only cooled by about 10°F each time it passes through the chiller, it is necessary to circulate the water through the chiller multiple times to achieve a lower outlet temperature, so most users use a storage tank.

Does water quality matter? Water quality is important. The water should be filtered and free of debris to prevent damage to the heat exchanger. Some chillers are equipped with water strainers to solve this problem.

What is the typical flow diagram for a chiller installation? Make - up water enters the circulating pump in the system, and the pump pumps the water through the chiller and then into the user's storage tank. A return pipe is connected from the storage tank back to the circulating pump, and then the water returns to the chiller to complete the cycle. If a strainer/filter is installed, it should be placed between the pump and the chiller.
