Abstract

The integrated solar absorption heat pump system includes an absorption heat pump assembly (AHPA) having a generator, a condenser in fluid communication with the generator, an evaporator/absorber in fluid communication with the condenser and the generator, and a heat exchanger in communicating relation with the evaporator/absorber; a solar collector in fluid communication with the generator of the AHPA; a photovoltaic thermal collector in communicating relation with the evaporator/absorber of the AHPA; a plurality of pumps configured for pumping a fluid throughout the system to provide the desired heating or cooling; a power storage source, e.g., a solar battery, in communicating relation with the photovoltaic thermal collector; and a coil unit in communicating relation to the evaporator/absorber for receiving an air-stream. The absorption heat pump assembly can include an absorber and a solution heat exchanger.

First claim
