Circulation Chillers

Contact us today for the perfect temperature control solution

Circulation chillers consist of compression process, condensation process, expansion process, and evaporation process. It uses limited refrigerant in a closed refrigeration system to repeatedly compress, condense, expand, and evaporate the refrigerant, and continuously absorbs heat and vaporizes at the evaporator for cooling and cooling. Refrigeration cycles include compression refrigeration cycle, absorption refrigeration cycle, adsorption refrigeration cycle, vapor injection refrigeration cycle and semiconductor refrigeration, etc.

How do circulation chillers work?

According to the principle of the refrigeration system, the low-temperature and low-pressure liquid refrigerant exchanges heat with the surrounding water in the evaporator. The evaporator absorbs the heat of the water and evaporates into a low-temperature and low-pressure gaseous state. During the evaporation process, the temperature of the refrigerant remains unchanged. The low-temperature and low-pressure gaseous refrigerant enters the compressed air. The machine is compressed by the compressor and is compressed into a high-temperature and high-pressure gaseous state, and then enters the condenser. In the condenser, heat exchange is performed with the indoor medium. Part of the heat of the high-temperature and high-pressure gaseous state is absorbed by the medium, and the temperature of the medium rises, and the refrigerant The exothermic condenser becomes a high-temperature and high-pressure liquid. The temperature of the condenser process remains unchanged, and then enters the expansion valve for throttling. Throttling is a rapid cooling process. The refrigerant becomes a low-temperature and low-pressure liquid. After this process, the refrigerant then enters the evaporator. The device performs heat exchange and evaporation, thereby realizing the entire process of the refrigeration system. This cycle is carried out continuously, so that the water can be continuously cooled.
