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 of refrigeration system. It can adjust the opening of the valve and change the refrigerant flow rate by using the temperature change of the air box head -LRB-temperature sensing packet) as a signal.

Thermostatic expansion valve adjustment process 1.1 Before thermostatic expansion valve adjustment inspection Before adjusting thermostatic expansion valve, must confirm that the equipment refrigeration abnormal is caused by the thermostatic expansion valvedeviation from the optimal operating p

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.

The safe operation of the valve should do the following:

The first major: Compressor

The role and practice of hot gas bypass valveThe energy regulation of the refrigeration system generally consists of the following waysCompressor parallel-multi-stage control; Variable speed compressor-frequency conversion, etc. ; With the unloading device of the compressor; Hot gas by-pass.For a co

Today we talk about the refrigeration system of three control valves, they are: evaporative pressure control valve, condensing pressure control valve, suction pressure control valve. They can optimize the performance of the refrigeration system, in the refrigeration system these valves are of great

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

Working principle and structure of four-way directional valve:The four-way reversing valve is composed of a main valve, a pilot valve and an electromagnetic coil. The pilot valve is used to control the main valve, and the differential pressure is used to switch the valve, so the reversing is flexibl
