WebThe limits in height to which liquid refrigerant can be piped without flash gas differ among engineers, but a maximum rise of 15 ft for R-12 is usually recommended. The controlling factor is the static head of the refrigerant at a given temperature. For R-12 at 97°F, this is .55 psi per ft of rise, and .57 psi per ft of rise at 70°F. In refrigeration, flash-gas is refrigerant in gas form produced spontaneously when the condensed liquid is subjected to boiling. The presence of flash-gas in the liquid lines reduces the efficiency of the refrigeration cycle. It can also lead several expansion systems to work improperly, and increase superheating at the evaporator. This is normally perceived as an unwanted condition caused by dissociation between the volume of the system, and the pressures and temperatures that allow t…
