Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a cooling circuit, a reheat circuit, a recovery circuit, and a control system. The cooling circuit includes a condenser, a compressor, an evaporator, and a three-way valve, and the HVAC system is configured to circulate refrigerant through the cooling circuit in a cooling operating mode. The reheat circuit includes a reheat heat exchanger, the compressor, the evaporator, and the three-way valve, and the HVAC system is configured to circulate refrigerant through the reheat circuit in a reheat operating mode. The recovery circuit extends between the condenser and the compressor and includes a recovery valve. The control system is configured to send a first signal to the three-way valve to switch the HVAC system between the cooling operating mode and the reheat operating mode and a second signal to the recovery valve to recover refrigerant from the cooling circuit at a subsequent time based on the first signal.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system, includes a cooling circuit, a reheat circuit, and a control system. The cooling circuit includes a condenser, a compressor, an evaporator, and a multi-directional valve, and the HVAC system is configured to circulate refrigerant through the cooling circuit in a cooling operating mode. The reheat circuit includes a reheat heat exchanger, the compressor, the evaporator, and the multi-directional valve, and the HVAC system is configured to circulate refrigerant through the reheat circuit in a reheat operating mode. The control system is configured to execute a switch between the cooling operating mode and the reheat operating mode by sending a signal to the multi-directional valve to adjust from a first position to a second position, interrupting a voltage provided to the compressor at a first time, and restoring application of the voltage to the compressor at a second time that is subsequent to the first time.

Abstract: A heating, ventilation, and air conditioning (HVAC) system. The HVAC system includes a sensor that detects a temperature of a heater of a heating component and emits a signal indicative of the temperature. A flow management device controls a flow of electricity or fuel from a power source to the heating component. A controller receives the signal from the sensor and operates the flow management device to block the flow of electricity or fuel to the heating component when the signal is indicative of the temperature being above a set point.

Abstract: A furnace system includes a burner assembly that includes a burner configured to produce a flame and a heat exchanger that includes a plurality of tube passes. The plurality of tube passes cooperatively forms a conduit for flowing combustion products generated by the burner assembly. Each tube pass of the plurality of tube passes overlaps with other tube passes of the plurality of tube passes. A first tube pass of the plurality of tube passes is configured to receive the flame, and the first tube pass includes a first plurality of surface enhancements extending radially outward from an outer surface of the first tube pass relative to a central axis of the first tube pass. The furnace system also includes a baffle that is coupled to the burner assembly, extends toward the first tube pass, and is configured to contact the flame and the first tube pass.

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.
