  • Systems and methods for transitioning between a cooling operating mode and a reheat operating mode
    Patent number: 11125449
    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.
