Although many of the principles will carry over to other types of refrigerants and drop ins.
R22 air conditioner pressures.
I haven t measured pressure drop yet on the evaporator.
R 22 was invented by a partnership with general motors and dupont back in the 1930 s.
Most homes with an air conditioning system manufactured before january 1 2010 use r 22 as the refrigerant.
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.
The ac compressor circulates the refrigerant through the system s pipes metering devices and coils.
The condensor coil is blowing out 118 degree air at a little over 250 psi.
This allows the unit to pull heat from inside air release it outdoors and cycle the cooled air throughout the house.
Refrigerant charge quantity for air conditioners heat pumps.
I will be sharing a pressure chart that may help you troubleshoot low pressure symptoms high pressure symptoms.
This article refers to troubleshooting refrigerant charge on 410a and r22 residential air conditioning systems.
Along with air conditioning it was also used in chillers ice rinks and many other applications.
The refrigerant gas used in the ac lines must be maintained at precise levels so the system pumps at the right pressure.

I will do that now.
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.
