The core components of a chiller unit include a compressor, condenser, evaporator, and throttling device. The compressor is responsible for compressing the refrigerant into high-temperature and high-pressure gas, while the condenser cools the high-temperature and high-pressure gas into high-pressure liquid through cooling water or air, releasing heat into the environment. Subsequently, the high-pressure liquid is depressurized through a throttling device and enters the evaporator, where it absorbs heat and evaporates, thereby reducing the temperature of the cooling water. Finally, the low-temperature and low-pressure refrigerant vapor is sucked in again by the compressor, starting a new cycle.

A chiller, also known as a chiller or refrigeration unit, is a refrigeration equipment that can provide low-temperature cooling water. It absorbs heat from the cooled object and discharges it into the environment through the circulation of refrigerant, thereby achieving the goal of reducing water temperature. Chillers are widely used in various fields such as industrial production, commercial buildings, data centers, medical facilities, food processing, refrigeration and air conditioning, and scientific research experiments.
