3.Refrigeration system
The refrigeration circulating system is as shown in the figure. TRF-4 is a single-system
full air-cooling frost-free refrigerator. The components of the refrigeration system are, in order,
compressor, evaporation coil, condenser, anti-condensation pipe, filter drier, capillary tube, fin
evaporator, return pipe and return transition pipe in the direction of refrigerant flow. The
schematic diagram of refrigeration is as follows:
