Recirculating Cooling Water Systems

Contact us today for the perfect temperature control solution

The recirculating cooling water system uses a compressor to refrigerate, and then performs heat exchange with water to reduce the temperature of the water and send it out through a circulation pump. At the same time, a temperature controller is used for temperature control, which has three functions: constant temperature, constant current, and constant voltage. It is widely used in supporting scientific instruments.

The principle of recirculating cooling water system

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 refrigerant temperature 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 gas state, and then enters the condenser. In the condenser, it exchanges heat with the indoor medium. Part of the heat of the high-temperature and high-pressure gas 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.

The main features of recirculating cooling water system:

1. Temperature, pressure and water level can be displayed, and flow rate display is optional.

2. Professionally designed dynamic temperature control with high precision, small temperature fluctuations, simple and convenient human-machine operation interface, and automatic memory of control parameters

3. Various refrigeration powers and circulating pump pressures can meet the cooling and constant temperature of various types of instruments.
