Reply: Matthew: The low side pressure when the compressor is running is a feature of the compressor's own pumping power combined with the properties of whatever device is being used to meter refrigerant into the system. That creates the pressure drop between high and low sides.R-22 refrigerant is the major refrigerant, or… it was. R-22 was invented by a partnership with General Motors and DuPont back in the 1930’s. 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. Along with air conditioning it was also used in ...
