Title:

REFRIGERATION CYCLING DEVICE

Document Type and Number:

WIPO Patent Application WO/2013/136368

Kind Code:

A1

Abstract:

The refrigeration cycling device has a cooling operation mode in which coolant from a compressor (1) is made to flow to an indoor heat exchanger (10) of an indoor unit (303) that has a cooling load, and a simultaneous cooling-hot water supply operation mode that simultaneously executes a hot water supply operation of making the coolant from the compressor (1) to flow to the water heat exchanger (16) of a hot water supply unit (304) that has a demand for a supply of hot water. As control modes for the simultaneous cooling-hot water supply operation mode, the device has a cooling priority mode that controls the operation frequency of the compressor (1) according to the cooling load and a hot water supply priority mode that controls the operation frequency of the compressor (1) according to the demand for hot water supply. The operation control unit (103) sets the control mode for the simultaneous cooling-heating-hot water supply operation mode to the cooling priority mode or the hot water supply priority mode according to the relationship between the cooling load and the hot water supply load.
