According to different cooling methods, chillers can be divided into two types: water-cooled and air-cooled. Water cooled chillers use cooling towers or cooling water systems to dissipate heat, which have advantages such as high refrigeration efficiency and stable operation, but require additional cooling water systems and space. The air-cooled chiller unit, on the other hand, directly dissipates the heat from the condenser into the air through a fan, without the need for an additional cooling water system. However, it is greatly affected by environmental temperature, and the refrigeration efficiency may be slightly lower.

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.

Industrial water coolers, as efficient and reliable refrigeration equipment, play an important role in multiple fields. With the continuous progress of technology and the continuous expansion of applications, industrial water chillers will achieve self-learning and self adjustment through the application of artificial intelligence and machine learning technology, improve operational efficiency and stability, and continue to play an important role in promoting the sustainable development of industrial production in the future.
