  • Heat pump for a HVACandR system
    Patent number: 11486612
    Abstract: Embodiments of the present disclosure relate to a heating, ventilating, air conditioning, and refrigeration (HVAC&R) system that includes a vapor compression system and an absorption heat pump. The vapor compression system includes a compressor configured to circulate refrigerant through the vapor compression system, an evaporator configured to place the refrigerant in thermal communication with a low temperature heat source, and a condenser configured to place the refrigerant in thermal communication with an intermediate fluid loop. The absorption heat pump includes an absorption evaporator configured to place a working fluid in thermal communication with the intermediate fluid loop, an absorber configured to mix the working fluid in an absorbent to form a mixture, a generator configured to heat the mixture and separate the working fluid from the absorbent, and an absorbent condenser configured to place the working fluid in thermal communication with a heating fluid.
