One side of the condenser 129 is provided with a condenser fan 130 to promote the flow of air to promote heat dissipation of the condenser 129.

By this configuration, the refrigerant compressed by the compressor 127 is moved to the condenser 129, and the heat is condensed by the condenser 129. The condensed refrigerant expands under reduced pressure in the expansion device 124 and flows into the evaporator 123. The refrigerant introduced into the evaporator 123 performs a cooling action to absorb the latent heat of the surroundings, and then flows back into the compressor 127 to be compressed and discharged.

By the way, in such a conventional electric refrigeration / refrigeration showcase, the evaporator 123 is arranged inside the cooling chamber 112, and the evaporator 123, the compressor 127, and the condenser 129 are assembled in an assembly line. And, since the refrigeration cycle components such as the circulation fan 125 and the condenser fan 130 are installed in the cabinet 110, respectively, the assembling process becomes complicated and lengthy, and is installed once in the assembly line to the refrigerant pipe. The connected refrigeration cycle component has a problem that it is difficult to separate from the cabinet 110, making it difficult to check and repair.

It is therefore an object of the present invention to provide an electric refrigeration / refrigeration showcase that can shorten the assembly process and facilitate inspection and maintenance.
