Title:

COMBINED AIR CONDITIONING AND HOT-WATER SUPPLY SYSTEM

Document Type and Number:

WIPO Patent Application WO/2016/084186

Kind Code:

A1

Abstract:

This combined air conditioning and hot-water supply system is provided with: a heat source unit equipped with a compressor and a heat source-side heat exchanger; an indoor unit for performing heating operation, the indoor unit being connected to the heat source unit and equipped with an indoor-side heat exchanger and an indoor-side throttling device; a hot-water supply unit for performing hot-water supply operation, the hot-water supply unit being connected to the heat source unit and equipped with a hot-water supply-side heat exchanger and a hot-water supply-side throttling device; and a control device for controlling the heat source unit. In addition, the control device comprises: a mode-switching section for switching the control mode of the combined air conditioning and hot-water supply system between a hot-water supply control mode in which the hot-water supply operation is predominant and a hot-water supply preheating mode in which the heating operation is predominant; and a condensation temperature control section that sets a target condensation temperature in accordance with the control mode. In the hot-water supply control mode, the condensation temperature control section sets the target condensation temperature according to the temperature of a heat carrier that is being heat-exchanged by the hot-water supply unit.
