A refrigeration based pool dehumidifier operates by drawing air over an evaporator coil, which transfers heat energy from the air to the refrigerant within the evaporator. As the heat energy is removed from the air, the moisture in the air condenses into water that drains into a condensate pan and down a drain. The cool, dry air passes through the reheat coil condenser and reabsorbs the heat energy from the hot gas refrigerant. The warm, dry air is discharged into the space. Heat energy can also be transferred to alternate refrigerant condensers to provide space cooling or pool water heating as specified.
