Heat pump system with chilled water tank and photovoltaic thermal 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 comprising at least one of crystalline silicon, amorphous silicon and cadmium telluride;
• a plurality of pumps, each of the pumps being configured for pumping a fluid throughout the system;
• a first hot water tank in fluid communication with the solar collector and the generator of the absorption heat pump assembly, the first hot water heat tank being configured for storing hot water from the generator and the solar collector;
• a second hot water tank in fluid communication with the photovoltaic thermal collector and the heat exchanger, the second hot water tank being configured for receiving hot water from the photovoltaic thermal collector and discharging the hot water into the heat exchanger;
• 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 the 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.
