  • EFFICIENT WATER SOURCE HEAT PUMP WITH HOT GAS REHEAT
    Publication number: 20040003609
    Abstract: A five element refrigeration system whereby heating and cooling functions of the system can be accomplished as in a reverse cycle system without needing to reverse the flow of the liquid through the system. The system comprises a refrigerant compressor, a pair of air side heat exchangers, an air blower to provide circulation for the air side heat exchangers, a pair of water side heat exchangers, and a reservoir to provide cooling water for the water side heat exchangers. The refrigerant compressor increases the pressure of a refrigerant flowing through it, causing it to circulate through the first air side heat exchanger, or a reheat coil. The refrigerant continues to the first water side heat exchanger, which acts as a condenser. In a cooling mode, the refrigerant continues to the second air side heat exchanger, which acts as an evaporator. In a heating mode, the refrigerant continues to the second water side heat exchanger, which acts as an evaporator.
