Dehumidifier dryer using ambient heat enhancement

An apparatus configured to receive an incoming air stream having a first temperature from within an enclosure and to exhaust an outgoing air stream into the enclosure, the incoming and outgoing air streams flowing in a flow direction, the apparatus comprising:

• a first evaporator through which the incoming air stream flows so that a second air stream exiting the first evaporator has a second temperature that is lower than the first temperature;
• a compressor;
• a condenser being within the enclosure;
• and
• a heat exchanger having a heat extraction portion and a heat depositing portion, wherein:
• the heat extraction portion is disposed in a third air stream outside of the enclosure, the third air stream having a third temperature greater than the second temperature,
• wherein the third air stream and the second air stream are not fluidly connected,
• wherein the heat depositing portion is disposed downstream of the evaporator with respect to the flow direction,
• wherein the heat depositing portion in the second airstream is located upstream of the condenser, and
• wherein the heat exchanger transfers sensible heat from the heat extraction portion in the third air stream to the heat depositing portion in the second air stream.
