  • Patent number: 10866002
    Abstract: A hybrid heat pump system comprising a heat pump loop integrated with a hydronic loop. The hybrid heat pump system offers multiple modes of operation to provide increased versatility and improved performance. Each of the loops can operate independently. In addition, the loops can operate in conjunction with each other in both heating and cooling modes. Still further, the hydronic loop can provide a reheat function when the heat pump loop is operating in the cooling mode to provide improved dehumidification of the air delivered to the conditioned space. The heat pump loop may include a hot gas bypass functionality for capacity control and/or freeze protection. The hydronic heat exchanger and the space heat exchanger of the heat pump loop may be combined in a compact single slab construction with a slit fin preventing cross-conduction between the heat exchanger sections.
