LOAD-SIDE RELAY UNIT AND COMPOUND AIR CONDITIONING/HOT WATER SUPPLY SYSTEM MOUNTING LOAD-SIDE RELAY UNIT THEREON

摘要

A load-side relay unit which houses a plurality of heat exchangers, and is designed for downsizing and simplified piping work; and a compound air conditioning/hot water supply system mounting the load-side relay unit thereon. The load-side relay unit (F) has mounted thereon two or more heat exchangers (a refrigerant-refrigerant heat exchanger (41) and a heat carrier-refrigerant heat exchanger (51)), wherein the two or more heat exchangers are configured in a substantially identical shape, and arranged such that the joint-forming surfaces of refrigerant piping (45) interconnecting the heat exchangers face each other.
