How to judge the presence of air in the air conditioner

In the refrigeration system, the non-condensable gases are mainly nitrogen, oxygen, hydrogen and water vapor in the air; because these working fluids do not condense with the refrigerant, they generally gather in the condenser or the liquid reservoir.

How to deal with the high pressure overload of the chiller

When the condenser heat dissipation is poor, the compressor efficiency is low and the operating current increases. When the high pressure rises to 19Kg/cm2, the compressor trips under the protection of the high pressure switch and the compressor stops runPﰨ2

Steps to determine the cause of the failure of the thermal expansion valve

1. When the refrigerant of the refrigeration system leaks completely, or there is no refrigerant flowing through the thermal expansion valve due to other reasons, the valve body of the thermal expansion valve will not be frosted.
