Document Type and Number:
WIPO Patent Application WO/2020/070890
Kind Code:
A1
Abstract:
An air conditioner (100) is provided with: a refrigeration cycle (RC) that has a compressor (32) and an indoor heat exchanger (64); a drain pan (140) that temporarily stores water stuck to the indoor heat exchanger and water falling as drain water; a drain pump (PO) that discharges the drain water stored in the drain pan to the outside; and a control device (20) that controls the operations of the refrigeration cycle and the drain pump. The control device carries out a freezing operation for causing the indoor heat exchanger to function as an evaporator and for setting the surface temperature of the indoor heat exchanger below freezing point, and drives the drain pump so as to satisfy the relationship of "driving time of drain pump after end of normal cooling operation < driving time of drain pump after freezing operation".
