Regulatory obejścia gorącego gazu - CPCE , KVC

CPCE and LG

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

KVC

KVC is a hot gas bypass regulator applied for the adaption of the compressor capacity to the actual evaporator load.
Placed in a bypass between high and low pressure sides of the refrigeration system, KVC imposes a lower limit on the compressor suction pressure by supplying the low pressure side with replacement capacity in the form of hot gas/cool gas from the high pressure side.
