Dust-free workshop, as the name suggests, needs to strictly control the number of dust particles in the air, but also need to accurately control the temperature, humidity and other environmental parameters. The right temperature is essential to ensure the stability of the production process and the quality of the product.

Principle of dust-free workshop cooling refrigeration

The refrigeration system of the dust-free workshop usually adopts the principle of compression refrigeration. This principle is based on the phase change process of the refrigerant in different states to achieve heat transfer. First, the compressor compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, at which time the temperature of the refrigerant rises sharply. Then, the high temperature and high pressure gaseous refrigerant enters the condenser, in the condenser through the heat exchange with the external cooling medium (such as water or air), the refrigerant releases heat and gradually condenses into high pressure liquid. Then, the high-pressure liquid refrigerant passes through the throttling device (such as the expansion valve), and the pressure and temperature of the refrigerant drop sharply due to the throttling effect, and it becomes a low-temperature and low-pressure liquid refrigerant. Finally, the low-temperature and low-pressure liquid refrigerant enters the evaporator, absorbs the heat in the dust-free workshop in the evaporator and vaporizes into low-temperature and low-pressure gaseous refrigerant, so as to achieve the cooling and cooling of the dust-free workshop. This cycle continues to bring out the heat in the workshop and maintain a stable low temperature environment in the workshop.
