  • Air conditioning system having actively controlled and stabilized hot gas reheat circuit
    Patent number: 10066860
    Abstract: A method for controlling an air conditioning system comprises routing refrigerant through an evaporator to cool air in a space, proportioning refrigerant flow from the evaporator between a condenser circuit and a hot gas reheat circuit that heats air leaving the evaporator, routing refrigerant flow from the condenser circuit and the hot gas reheat circuit through an expansion device and back to the evaporator, monitoring a first temperature at the evaporator, stabilizing proportioning of refrigerant flow between the condenser circuit and the hot gas reheat circuit based on the monitored first temperature.

  • INTEGRATED VENTILATION UNIT
    Publication number: 20180119981
    Abstract: An integrated ventilation unit configured to provide ventilation and conditioned air to an indoor space may include a heat pump system, an energy recovery device and a control unit. The heat pump system may include a first coil located at a supply air side of the ventilation unit, a second coil located at an exhaust air side of the ventilation unit, and a compressor. The energy recovery device may be configured to transfer heat between a return air stream and a supply air stream and the control unit may be configured to control operation of the heat pump system and the energy recovery device.
