Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/100729
Kind Code:
A1
Abstract:
This refrigeration cycle device has: a heat source unit including a compressor; an indoor unit which performs heat exchange between air in a space to be air-conditioned and a refrigerant flowing and circulating through an air-conditioning branch pipe that branches from a refrigerant pipe connected to the compressor; a water heater which performs heat exchange between water and a refrigerant flowing and circulating through a water-heating branch pipe that branches from the refrigerant pipe; a pressure sensor which detects the discharge pressure of the compressor; and a control unit which controls the compressor according to the operation states of the indoor unit and the water heater, wherein when the water heater is operated after the cooling operation of the indoor unit is stopped, the control unit sets an upper limit value as a target value for the discharge pressure of the compressor and controls the compressor so that the discharge pressure detected by the pressure sensor follows the upper limit value.
