System and method for modulating hot gas reheat utilizing multiple compressor systems

A system for modulating hot gas reheat operation of a heating, ventilation, and/or air conditioning (HVAC) system, wherein the HVAC system is configured to regulate air provided to a plurality of zones, the system comprising:

• a reheat coil;
• a plurality of hot gas reheat circuits, wherein each hot gas reheat circuit of the plurality of reheat circuits includes the reheat coil;
• an evaporator;
• a plurality of cooling circuits, wherein each cooling circuit of the plurality of reheat circuits includes a respective condenser and the evaporator;
• a plurality of compressors, wherein each compressor of the plurality of compressors is coupled both to a respective hot gas reheat circuit of the plurality of hot gas reheat circuits and a respective cooling circuit of the plurality of cooling circuits;
• and
• a plurality of multi-directional reheat valves disposed at different junctions between the plurality of hot gas reheat circuits and the plurality of cooling circuits.

A system for modulating hot gas reheat operation of a heating, ventilation, and/or air conditioning (HVAC) system, wherein the HVAC system is configured to regulate air provided to a plurality of zones, the system comprising:

• a plurality of compressors;
• and
• a multi-directional reheat valve;
• and
• wherein in response to a call for dehumidification in the absence of a call for cooling, the plurality of compressors are configured to be sequentially energized with a first compressor of the plurality of compressors energized in a reheat mode, a second compressor of the plurality of compressors energized in a cooling mode, a third compressor of the plurality of compressors energized in a reheat mode initially at full capacity, and a fourth compressor of the plurality of compressors energized in a cooling mode, and wherein, when the third compressor is energized in the reheat mode initially at full capacity and when a temperature of supply air is not at a neutral temperature, the multi-directional reheat valve is configured to adjust a capacity of the reheat mode of the third compressor in response to a modulating signal.
