What is a Thermostatic Expansion Valve?

The thermostatic expansion valve (TXV or TEV), also called the thermal expansion valve, controls the openness degree through the control of the superheat of the gaseous refrigerant at the outlet of the evaporator.

Compressor operation in the heart of the refrigeration system in 2020

Compressor operation in the heart of the refrigeration system in 2020 A compressor is a fluid machine that raises low-pressure gas to high-pressure gas. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby achieving compression-condensation (heat release) )-Expansion-evaporation (heat absorption) refrigeration cycle.

Basic knowledge of air energy

At present, the most commonly used vapor compression heat pumps, compressors, evaporators, condensers, and throttle valves are the four main components. Other auxiliary components include fans, four-way valves, liquid storage tanks, gas-liquid separators, copper pipes, and Protectors and electronic control parts used to ensure the normal operation of the machine, etc. Direct-heating models also include a water flow regulating valve.

Classification, principle and use of refrigeration compressors

Classification, principle and use of refrigeration compressors<br></br> The function of refrigeration compressor:<br></br> The refrigeration compressor is the "heart" of the refrigeration system. It absorbs the refrigerant vapor from the evaporator, increases the pressure and discharges it to the condenser, so that the refrigerant circulates in the system. Can be used in refrigeration systems and heat pump systems

Three requirements of modern industry for compressed air

In many chemical, food, ceramic, electronic industries and other industrial sectors that use compressed air energy, compressed air pollution can destroy other processes. Therefore, in order to improve the service life and reliability of pneumatic equipment and systems, and ensure the quality of the products produced, the compressed air must be purified and dried.
