Abstract: A system for modulating hot gas reheat operation of a heating, ventilation, and/or air conditioning (HVAC) system with multiple compressors, wherein the HVAC system is configured to regulate air provided to multiple zones. The system includes a controller configured to respond to a call for dehumidification in the absence of a call for cooling by sequentially energizing a first compressor of the multiple compressors in a reheat mode of the first compressor, energizing a second compressor of the multiple compressors in a cooling mode of the second compressor, energizing a third compressor of the multiple compressors in a reheat mode of the third compressor initially at full capacity, and energizing a fourth compressor of the multiple compressors in a cooling mode of the fourth compressor.

Abstract: A heating, ventilating, and air conditioning (HVAC) system includes a compressor configured to circulate a fluid through the HVAC system, a first coil configured to establish a first heat exchange relationship between the fluid and a first airflow across the first coil, a second coil configured to establish a second heat exchange relationship between the fluid and a second airflow across the second coil, and a fan configured to direct the first airflow across the first coil, the second airflow across the second coil, or both, and where the first airflow across the first coil is directed to be isolated from the second airflow across the second coil, and the first airflow is blocked from flowing across the first coil when the first coil is inactive and the second airflow is blocked from flowing across the second coil when the second coil is inactive.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) unit includes a first sensor disposed adjacent to an inlet of an evaporator configured to receive an airflow. The HVAC unit includes a second sensor disposed adjacent to an outlet of a reheat coil positioned downstream of the evaporator and configured to expel the airflow. The HVAC unit also includes a controller configured to regulate operation of a modulating reheat valve to adjust flow of a working fluid in thermal communication with the airflow to control a difference between a measurement of the first sensor and a measurement of the second sensor.

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.
