This system is intended primarily for direct expansion systems. It features Humidity Control, Total Part Load Performance, Energy Efficiency, Controllable Hot Gas Reheat, Passive Reheat, Subcool Reheat Option, and is Neutral BTU Ventilation capable. The Subcool Reheat of refrigerant for improved dehumidification uses the cold supply air to cool the liquid refrigerant before it enters the evaporator coil. This process is called "Subcooling." This process increases the moisture removal capability of the Air Conditioning System and passively reheats the supply air to introduce cool, drier air into a building. Properly installed, a Subcool Reheat system will improve the moisture removal while lowering the relative humidity of the supply air served by an Air Conditioning System.
