の範囲第１項記載のシヨーケース。[Claims for Utility Model Registration] (1) Includes two systems of evaporators arranged in the air passage inside the case body, and performs defrosting operation by directly sending refrigerant from the condenser to the first evaporator. In the first mode, the refrigerant is sent to the second evaporator through the expansion valve for cooling operation, and in the first mode, the refrigerant from the condenser is directly sent to the second evaporator for defrosting operation, and the refrigerant is sent through the expansion valve to the first evaporator. The second one is sent to the evaporator and is operated for cooling.
and a third mode in which refrigerant from the condenser is sent to the first and second evaporators for cooling operation through an expansion valve.
As the second evaporator, an evaporator consisting of upper and lower layers each having an independent refrigerant inlet and outlet is used. The refrigerant from the condenser is first sent to the lower layer of the evaporator, and then the upper layer A case that is designed to be sent to. (2) The show case according to claim 1, which is characterized by using an evaporator in which the volume of the lower layer is smaller than that of the upper layer.
