Document Type and Number:
Japanese Patent JP2017116253
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a merchandise cooling/heating device capable of preventing temperature drop of a compressor and capable of performing efficient heating by a heat pump operation.SOLUTION: A merchandise cooling/heating device includes: a plurality of outside fans provided between a compressor 20 and an outside condenser; a wind direction adjustment member 60 arranged so as to hit the wind blown from a part of the outside fan to the compressor 20 or shield it; and an outside air temperature sensor and a refrigerant temperature sensor 51 for detecting a capability state of the heat pump operation. In the case where it is detected that the capability of the heat pump operation is low by the outside air temperature sensor and the refrigerant temperature sensor 51, with respect to the operation of the first outside fan 23a arranged so as to shield the blowing air to the compressor 20 by the wind direction adjustment member 60, the rotational frequency of the outside fan 23b arranged so as to hit the blowing air to the compressor 20 is reduced.SELECTED DRAWING: Figure 3
