Heat pump water heater in public bathing rooms.


In most conditions, the excess heat of exhaust water discharged from household or public bathing-rooms is not utilized, causing excessive energy waste. Hence, it is suggested that a heat pump that uses the exhaust water as a low-temperature heat source should be implemented to reclaim excess heat to produce sanitary hot water for the public bathing-rooms. In point of this view we call the above-mentioned heat pump 'bathing room heat pump water heater'. In this paper we present the components and flow diagram of the heat pump water heater with heat recovery applied in public bathing-room, analyzes its thermal characteristics from thermodynamic principles, and calculates its limit heating coefficient under different typical working-conditions.
