Fig. 5-1 Functional diagram
The unit functioning is based on the cooling cycle principle: heat
transfer occurs by means of a refrigerant, which absorbs heat in the
evaporator and then releases it in the condenser. All this takes place
within a closed loop. The refrigerant is pressurised by an electrically
driven compressor, fluidised in the condenser, atomised by means of a
throttle valve and evaporated in the evaporator.
The evaporator is located inside the refrigerated trailer, while the
condenser on the outside.
The trailer refrigeration unit is equipped with a forced-ventilated
condenser and evaporator, axial fans and electronic temperature
control.
