HYBRID HEAT PUMP SYSTEM USING LOW TEMPERATURE SEA WATER

摘要

The present invention relates to a hybrid heat pump which produces hot water using an electric heat pump (100) and an absorption heat pump (200). Provided is a hybrid heat pump combining the electric heat pump (100) and the absorption heat pump (200). The electric heat pump comprises: a first evaporator (110) for receiving sea water, lowering the temperature by heat exchange and discharge of the sea water; and a first condenser (120) for increasing temperature of the sea water flowing in and providing service hot water (W0) using the absorption heat pump. The absorption heat pump (200) comprises: a second evaporator (210) for lowering the temperature of the service hot water by exchanging heat of the service hot water supplied from the first condenser and resupplying the water to the first condenser; a second absorption unit (220) for producing first hot water (W2) by increasing the temperature of source water (W1); a second condenser (230) for producing second hot water (W3) by receiving the first hot water from the second absorption unit and increasing the temperature of the first hot water; and a second recycle unit (240) for generating vapor by heating a coolant flowing in through the absorption heat pump by receiving heat from an external heat source.
