WIPO Patent Application WO/2021/095423
Kind Code:
A1
Abstract:
The present invention is provided with a control unit (C) that controls a refrigerant circuit (11) and a blower (52) so as to sequentially perform first operation, second operation, and third operation. The first operation is an operation to operate the blower (52) and perform a first refrigeration cycle to produce condensation water or ice in a utilization heat exchanger (53) serving as an evaporator. The second operation is an operation to operate the blower (52) and stop the utilization heat exchanger (53). The third operation is an operation to operate the blower (52) and perform a second refrigeration cycle to heat the air using the utilization heat exchanger (53) serving as a radiator. The execution time of the third operation is shorter than the execution time of the second operation.
