Combination split system air conditioner and compression cycle domestic hot water heating apparatus

摘要

A conventional split system air conditioner is combined with a compression cycle or heat pump system for supplying heat to a domestic water heater. The units are combined in such a way that significant energy savings can be achieved by circulating air in series through the outdoor evaporator coil of the hot water heating system and then through the condensing coil of the heat pump, or vice-versa. This has the advantage of increasing the coefficient of performance for both systems. The direction of air flow will be selected on the basis of achieving the greatest improvement in energy savings and can be provided with automatic reversal of the air flow direction, depending on the ambient air quality and/or the operating state of either unit.
