  • Patent number: 11965672
    Abstract: A heat pump system includes a compressor, a usage side heat exchanger, a heat source side heat exchanger, an expansion mechanism, a main refrigerant flow control valve switchable between cooling and heating modes, a gas reheat heat exchanger, a fan, and a secondary refrigerant flow control device switchable between first, second, and third modes. Refrigerant flows from the compressor discharge line to the main refrigerant flow control device in the first mode. Refrigerant flows from discharge line to gas reheat heat exchanger and then main refrigerant flow control valve in the second mode. Refrigerant flows both from discharge line to gas reheat heat exchanger and then main refrigerant flow control valve, and from discharge line to main refrigerant flow control valve without flowing through the gas reheat heat exchanger in the third mode. Refrigerant flows to the usage side and hot gas reheat heat exchanger in the heating mode.

  • Patent number: 11624518
    Abstract: A method of conditioning air includes controlling a secondary refrigerant flow control valve to select between a first mode in which refrigerant flows from a discharge line to a main refrigerant flow control valve, and a second mode in which refrigerant flows from the discharge line to a gas reheat heat exchanger and then flows to the main refrigerant flow control valve. A heat transfer medium flow control valve is controlled to adjust the flow of the heat transfer medium into a heat source side heat exchanger. The heat transfer medium flow control valve allows the heat transfer medium to flow to the heat source side heat exchanger when the secondary refrigerant flow control valve is in the first mode, and adjusts the flow of the heat transfer medium to the heat source side heat exchanger when the secondary refrigerant flow control valve is in the second mode.

  • Patent number: 11002452
    Abstract: A heat pump system includes a compressor, usage side heat exchanger, heat source side heat exchanger, expansion mechanism, main refrigerant flow control device switchable between cooling and heating modes, gas reheat heat exchanger connected in the refrigerant circuit, a fan disposed to direct an airflow across the usage side heat exchanger and the gas reheat heat exchanger into a target space, and a secondary refrigerant flow control device switchable between first and second modes. Refrigerant flows from the discharge line to the main refrigerant flow control device in the heating mode and the cooling mode in the first mode. Refrigerant flows from the discharge line to the gas reheat heat exchanger in a gas reheat mode and then flows to the main refrigerant flow control device in the second mode. A flow of the heat transfer medium to the heat source side heat exchanger is adjustable.
