In the refrigeration system of industrial chillers, the main role of valves is to control the flow of refrigerant and direction, in daily use, also need to often use the valve, valves are used when industrial chillers need to be shut down or turned on. Because of its daily use of high frequency, so

Thermal expansion valve is an important automatic control component in refrigeration system. It can adjust the opening of the valve and change the refrigerant flow rate by using the temperature change of the gas box head -LRB-temperature sensing packet) as a signal.

In the air conditioning refrigeration system, the drying filter is not the refrigeration operation part, but is the refrigeration system indispensable important auxiliary part.

The four main parts of refrigerating system in cold storage include: refrigerating compressor, condenser, throttling device (expansion valve, capillary, etc.) and evaporator (air cooler) . The four main components and refrigerants become the necessary conditions for realizing the refrigeration cycle

The pressure controller has two main functions:

A refrigeration unit system is a large industrial refrigeration unit whose core component is the refrigeration unit. The unit consists of a compressor, condenser, evaporator and expansion valve, etc., and the cooling and cooling of air or fluids is realized through the concerted work of these compon
