R22 Air Conditioner Pressures

The refrigerant gas used in the ac lines must be maintained at precise levels so the system pumps at the right pressure.

R22 air conditioner pressures.

The ac compressor circulates the refrigerant through the system s pipes metering devices and coils. In the 1950 s the use of r 22 exploded and for nearly sixty years it was the refrigerant to be used in home office and commercial air conditioning. I haven t measured pressure drop yet on the evaporator. This air conditioning repair article series discusses the the diagnosis and correction of abnormal air conditioner refrigerant line pressures as a means for evaluating the condition of the air conditioner compressor motor which in turn is a step in how we evaluate and correct lost or reduced air conditioner cooling capacity.

Ac systems with a low r 22 charge do not perform at peak efficiency. I will do that now. This article refers to troubleshooting refrigerant charge on 410a and r22 residential air conditioning systems. Proper refrigerant charging can be aided by measuring the pressure of the system while filling.

R 22 was invented by a partnership with general motors and dupont back in the 1930 s. The supply duct is blowing out 66 degree air at the closest supply vent to the air handler with the low side at a little over 40 psi. I will be sharing a pressure chart that may help you troubleshoot low pressure symptoms high pressure symptoms.
