Cold and hot shock alternating high and low temperature test chamber
is mainly simulation extreme natural environment change on goods to carry out the inspection, heating and refrigeration unit is critical for machine equipment, refrigeration unit is more complex, relatively hot and cold impact test box of refrigeration fittings have?
Hot and cold impact test chamber heating system software generally is to choose the power of heating equipment, and the operation of the refrigeration unit involves more multifarious, all refrigeration units must run a lot of spare parts, so hot and cold impact test chamber refrigeration fittings have?
Below to let us to know: 1, refrigeration compressor, mainly is the hot and cold impact test box end of cryogenic pressure vapour refrigerant into ultrahigh pressure gas refrigerants.
2, cooler, its efficacy is to put the super high pressure gas refrigerants cold suspected into normal temperature under high pressure liquid refrigerant.
3, throttle valve group (
The capillaries or air conditioner expansion valve)
: the room temperature under high pressure liquid refrigerant according to the over-current protection into the bottom of the cryogenic pressure vapor liquid compounds.
4, air conditioning evaporator: using the basic principle of evaporation heat him refrigerant flow organization out into the bottom of the cryogenic pressure gas refrigerants, refrigeration compressor.
5, oil separator: attached the maintenance spare parts, the grease in the isolated refrigerant immediately sent to the refrigeration compressor, refrigeration compressor to ensure runtime amount of grease.
No grease into the cooler and air conditioning evaporator, heat transfer effect.
Except as described in the key spare parts, additional also has other relay, gas-liquid separator, dry manic filter device and other parts, in order to guarantee the quality of hot and cold impact test box equipment and refrigeration effect, on key refrigeration equipment used overseas authentic brand spare parts, for machine equipment to produce stronger, more stable cooling characteristics.
The above explanation is the hot and cold impact test chamber refrigeration fittings, hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline (
