R22 refrigerant manufacturer introduce refrigerator filled volume of the refrigerant

don't know what friends for refrigerator filled volume of the refrigerant, washed many right? Today, the staff of r22 refrigerant manufacturer for everyone to do a detailed introduction, let's take a look at related introduction.

r22 refrigerant manufacturer is introduced for sure one of the commonly used method of refrigerator filled volume of the refrigerant, is observed for the fluid flow of refrigerant in the liquid lens of tube covering. When liquid flow can be clearly seen, can think refrigerant has correct filling, if there is a bubble, usually lack of refrigerant, but it could be depending on the liquid mirror the liquid pipe scaling part or the condensing pressure of rapid change, the refrigerant pressure drop.

of course, can also according to the operation condition of the system is running a judgment, first the adjustment of the expansion valve lever must be set in the middle position, that is to keep the factory status ( Expansion valve generally not adjusted) 。 Then add liquid to low pressure is akin to the evaporation temperature refrigerator ( Lower than the base temperature 5 ~ 8 degrees) The corresponding pressure shall prevail. Experienced technicians, can also according to the outlet air temperature of air cooling condenser, compressor gas condensation or frost, current, expansion valve, frost situation to judge.

refrigerator filling refrigerant operation principle: library temperature above 0 degrees, any part of the system are not allowed to have frost phenomenon appear! Only library temperature below zero, began to frost's expansion valve outlet pipe, and then gradually extended to the evaporator, and then back to the trachea, until the inspiratory Angle valve in the compressor.

the above information is provided by r22 refrigerant manufacturer, hope to be able to bring you some help, if you have a demand on refrigerant r22, welcomed the advisory negotiate with us.
