VAPOR COMPRESSION REFRIGERATION EQUIPMENTS
VAPOR COMPRESSION REFRIGERATION EQUIPMENTS Equipments of vapor compression systems include compressors, condensers, evaporators & expansion valves. These also include piping and various controls. COMPRESSORS (i) Reciprocating compressors: used with (a) lower boiling temperature (much below 00C) refrigerants (ii) low specific volume at – 150C, (c) (pcond – –pevap) > 3.5 atm ( R-22, NH3, etc.)….
