1. A portable dehumidifier, comprising:
- a housing having an inlet opening for receiving air of a first humidity and an exit opening for expelling air of a second humidity;
an evaporator positioned adjacent to said inlet opening, said evaporator having an inlet tube and an outlet tube;
a compressor interconnected to the evaporator via a outlet tube of the evaporator, the compressor having an exit tube;
a condenser interconnected to the exit tube of the compressor, the condenser having an exit tube that is interconnected to a thermal expansion valve that is also associated with the inlet tube of the evaporator;
a sensor associated with the exit tube of the evaporator; and
wherein the sensor communicates with the thermal expansion valve to control flow of refrigerant flowing through the evaporator, compressor, and tubes.
