Page 14: Refrigeration System
Instruction book Refrigeration system Refrigerant flow diagram Reference Name Refrigerant compressor Condenser Evaporator Expansion capillary tube Refrigerant filter Description Compressor (1) delivers hot, high-pressure refrigerant gas which flows through condenser (2) where most of the refrigerant condenses. The liquid flows through the refrigerant dryer/filter (8) to capillary tube (7). The refrigerant leaves the capillary tube at evaporating pressure. -
Page 15: Electrical System
Instruction book Reference Name Cooling fan Hot gas bypass valve Description The condenser pressure must be kept as constant as possible to obtain stable operation. Fan control switch therefore stops and starts the cooling fan (3). If, under partial or no load, the evaporator pressure drops below a certain level, the hot gas bypass valve opens and hot, high-pressure gas is fed to the evaporator circuit to prevent the evaporator pressure from dropping any further. -
