AIR CONDITIONING AND HOT-WATER SUPPLY COMPOSITE SYSTEM

Title:

AIR CONDITIONING AND HOT-WATER SUPPLY COMPOSITE SYSTEM

Document Type and Number:

WIPO Patent Application WO/2011/125111

Kind Code:

A1

Abstract:

Provided is an air conditioning and hot-water supply composite system which is highly efficient and which appropriately controls the superheating and the supercooling of a heat exchanger, to maintain a high hot-water supply performance even in a high-temperature atmosphere. When the evaporating pressure or the evaporating temperature calculated from the evaporating pressure reaches or exceeds a first predetermined value, an air conditioning and hot-water supply composite system (100) controls the superheating of refrigerant on the low-pressure gas side of a supercooling heat exchanger (18) or the supercooling of refrigerant on the high-pressure liquid side of the supercooling heat exchanger (18) in accordance with the aperture of a low-pressure bypass decompression mechanism (23), so that the evaporating pressure or the evaporating temperature calculated from the evaporating pressure is the first predetermined value or less.
