CPCE
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)
Features and benefits
- Refrigerant: HCFC, HFC and HC
- Compressor capacity at minimum suction temperature: Q1 in [kW]
- Evaporator load at minimum suction temperature: Q2 in [kW]
- Liquid temperature ahead of expansion valve: tl [°C]
- Reduction of suction temperature/suction pressure in [K]
- Connection type: flare or solder
- Connection size in [in] or [mm] Selection Example When selecting the appropriate valve it may be necessary to convert the actual capacity using a correction factor. This is required when system conditions are different from table conditions. The following examples illustrate how this is done.
- Refrigerant: R404A
