    Abstract: A furnace of a heating, ventilation, and/or air conditioning (HVAC) system includes a heat exchange tube configured to receive a working fluid from a burner and a modulating valve fluidly coupled to the burner. The modulating valve is configured to regulate an amount of fuel supplied to the burner to generate the working fluid. The furnace also includes a blower configured to draw the working fluid through the heat exchange tube, a motor drive configured to adjust a speed of the blower, and a controller configured to adjust a position of the modulating valve and to control the motor drive to adjust the speed of the blower based on a temperature of air discharged from the HVAC system.

    Abstract: A heating, ventilating, and air conditioning (HVAC) furnace includes a condensing furnace and a condensate removal system associated with the condensing furnace. The condensate removal system includes an electrolyzer having a container that may collect a condensate generated from an exhaust gas produced in the condensing furnace and an electrode disposed within the container and that may apply an electric current to the condensate to electrolyze the condensate and thereby generate condensate gases.

    Abstract: The present disclosure is directed to a single compressor HVAC system with hot gas reheat. The system includes a single compressor, a pair of condensers, a reheat heat exchanger, an evaporator, and an expansion device. Within the system, the refrigerant exiting the compressor is separated into two portions. In the cooling mode, the first and second portions of the refrigerant are directed from the compressor through the two condensers in parallel. In the reheat mode, the first portion of the refrigerant is directed through the first condenser, while the second portion of the refrigerant is directed through the reheat heat exchanger. The system also may include a head pressure control device that is designed to maintain the compressor discharge pressure within a desired range by adjusting the condenser fan speed.

    Abstract translation: 本公开涉及具有热气体再热的单个压缩机HVAC系统。 该系统包括单个压缩机，一对冷凝器，再热换热器，蒸发器和膨胀装置。 在系统内，离开压缩机的制冷剂分成两部分。 在冷却模式中，制冷剂的第一和第二部分平行地从压缩机通过两个冷凝器。 在再热模式中，制冷剂的第一部分被引导通过第一冷凝器，而制冷剂的第二部分被引导通过再热换热器。 该系统还可以包括头压力控制装置，其被设计成通过调节冷凝器风扇速度将压缩机排出压力维持在期望范围内。
