Purpose of hot gas reheat coil
WebHot gas reheat is when you add discharge heat back to the conditioned space. When you use reheat for dehumidification, you cool for the purpose of dehumidification and then add sensible heat to remove moisture on the coil. So, you don't overcool the space to an uncomfortable level. Hot gas reheat uses waste heat from the equipment to remove ... 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 ... 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.
