Refrigerant head pressure

WebOct 16, 2005 · Technically, "head pressure" is compressor discharge pressure. This pressure is formed by compressing superheated refrigerant vapor and discharging the vapor into the condenser. True "head pressure" is measured at the discharge side of the compressor, not at the liquid line service valve such as on most split systems. Webthe “condensing pressure” in a refrigeration or A/C system. Traditional refrigeration systems maintain a fixed head pressure above 105°F, typically relying on mechanical head-pressure control valves or fan cycling to maintain fixed pressure. The term “floating head pressure” is synonymous with
