Among them, the refrigerating system is preferably a hermetic refrigerating system for performing a vapor compression cycle for cooling air inside the storage chamber 21. The hermetic refrigeration system includes a compressor 261, a condenser 262, an expansion device, and an evaporator 263 fluidly connected in series and filled with a refrigerant. Within a sealed refrigeration system, gaseous refrigerant flows into a compressor 261, which compressor 261 operates to increase the pressure of the refrigerant. The compression of the refrigerant raises its temperature, which is lowered by the passage of gaseous refrigerant through the condenser 262. In the condenser 262, heat exchange with ambient air is performed to cool the refrigerant and condense the refrigerant into a liquid state.

An expansion device (e.g., a mechanical valve, a capillary tube, an electronic expansion valve, or other restriction device) receives liquid refrigerant from the condenser 262. From the expansion device, the liquid refrigerant enters the evaporator 263. Upon exiting the expansion device and entering the evaporator 263, the liquid refrigerant drops in pressure and evaporates. The evaporator 263 is cool with respect to the storage chamber 21 due to a pressure drop and a phase change of the refrigerant. As can be seen, cooling air is generated and cools the storage chamber 21. Thus, the evaporator 263 is a heat exchanger that transfers heat from air passing through the evaporator 263 to refrigerant flowing through the evaporator 263.
