Integrated solar absorption heat pump system with evacuated tube solar collector

An integrated solar absorption heat pump system, comprising:

• an absorption heat pump assembly including a generator, a condenser in fluid communication with the generator, an evaporator/absorber in fluid communication with the condenser and the generator, an expansion valve in fluid communication with the condenser, the generator and the evaporator/absorber, and a heat exchanger in communicating relation with the evaporator/absorber;
• an evacuated tube solar collector in fluid communication with the generator of the absorption heat pump assembly;
• a photovoltaic thermal collector in communicating relation with the evaporator/absorber of the absorption heat pump assembly, wherein the photovoltaic thermal collector is a sheet-and-tube solar collector having an absorber covered by a photovoltaic layer;
• a plurality of pumps, each of the pumps being configured for pumping a fluid throughout the system;
• a power storage source in communicating relation with the photovoltaic thermal collector;
• a coil unit in communicating relation to the evaporator/absorber;
• a water tank in fluid communication with the condenser and the evaporator/absorber of the absorption heat pump assembly;
• a chilled water tank in fluid communication with the evaporator/absorber of the absorption heat pump assembly;
• a weak solution tank in fluid communication with the evaporator/absorber and an absorber of the absorption heat pump assembly;
• and
• a concentrated solution tank in fluid communication with the evaporator/absorber of the absorption heat pump assembly.
