Purpose of hot gas reheat coil
WebNov 6, 2024 · How does a hot gas reheat coil work? Hot gas reheat coils work by routing a portion of the gas that would go to the condenser in a standard system to a reheat coil. This coil then brings the air back up to a suitable temperature. Next, the air travels to a supply fan and then to the system’s primary heating coil. WebA humidity control method is provided for a multi-stage cooling system having two or more refrigerant circuits that balances humidity control and cooling demand. Each refrigerant circuit includes a compressor, a condenser and an evaporator. A hot gas reheat circuit having a hot gas reheat coil is connected to one of the refrigerant circuits and is placed in …

WebControlling Humidity: Humidity control can be enhanced using reheat coils, just as for ventilation requirements. When the local humidity is too high, then drier cooler air can be added, and then slightly reheated to avoid sub cooling. HOT WATER HEAT Most manufacturers of VAV terminals offer a hot water coil selection program. This selection ... WebHot Gas Reheat Mode (HGSV open, LLSV closed) When there is a call for dehumidification without a call for cooling, a portion of the hot gas from the compressor bypasses the condenser coil and is fed into the liquid line. At this point, it is mixed with the sub-cooled refrigerant leaving the condenser coil.
WebThe reheat coils of the HVAC system heat the air before it leaves the system. This prevents over-cooling of your room due to the low temperature of the dehumidified air. As a result, the humidity of the air also fluctuates and this is how the reheat coils heat the system. The frequent turning on & off of the compressor also plays a major role ...
