DANFOS Hot gas bypass regulator Types TUH, TCHE and TGHE For Air Conditioning
CPCE hot gas bypass regulator adapt compressor capacity to actual evaporator load.
They are designed for installation in a bypass line between the low and high pressure sides of the refrigeration system, for hot gas injection between the evaporator and thermostatic expansion valve.
Injection should be arranged to occur through an LG liquid gas mixer.
CPCE hot gas bypass regulator :
• Superior control accuracy
• Direct connection to system suction line regulates hot gas injection independent of evaporator pressure drop
• The regulator increases evaporator gas velocity, thus ensuring better oil return to compressor
• Protection against too low an evaporating temperature, i.e. prevents evaporator icing
• May be used in the following EX range: Category 3 (Zone 2)
LG liquid gas mixer :
• LG provides homogeneous mixing of the liquid and hot gas refrigerant injected into the evaporator
• Prevents high suction superheat by combining hot gas injection with expansion valve characteristics
• LG can be used for hot gas defrosting or reverse cycle systems
