OSTI ID:5604996
A dehumidifier system is described for a heater furnace-air duct system within a building in which: the dehumidifier system includes an evaporator coil positioned in the furnace so that air from a blower in the furnace is directed through the evaporator coil and directed into the duct system as required for dehumidification during periods other than during air conditioning and heating, the dehumidifier system and an air conditioner system associated with the furnace each includes separate compressor-condensers within the same housing outside the building area to be cooled and dehumidified, the separate compressor-condenser of the dehumidifier refrigerant includes feed and return lines connected between the compressor-condenser and the evaporator coil in the furnace, an air conditioner cooling coil in the furnace through which air from the blower in the furnace is directed for air conditioning a desired enclosed area; the separate compressor-condenser of the air conditioner system includes refrigerant feed and return lines connected between the compressor-condenser and the cooling coil in the furnace, the evaporator coil of the dehumidifier is placed in the furnace independent of and upstream from the air conditioner cooling coil; and the system includes a control system that allows the dehumidifier system to operate only when the air conditioner system and the furnace are not operating.
