Abstract
A dehumidifier includes a humidistat switch to provide power to the compressor and fan when the ambient humidity exceeds a given level. The power to the compressor is also controlled by a thermostat switch and a timer. When the dehumidifier is operating in an environment that is below a given temperature, the compressor is periodically turned off for a short interval to melt any ice that has formed on the compressor coils.
Claims7
A dehumidifier comprising:
- an evaporator coil;
- a condensor coil;
- a compressor for circulating a refrigerant through the evaporator and condensor coils;
- a fan for circulating air over the evaporator coil;
- humidistatically controlled means for applying power to the compressor and the fan;
- and
- means for periodically disconnnecting the application of power to said compressor when the ambient temperature falls below a given value.
A dehumidifier comprising:
- first and second power terminals for applying electrical power to the dehumidifier;
- an electric fan having first and second terminals, the first terminal being connected to said first power terminal;
- a humidistat controlled switch for coupling said second power terminal to the second terminal of the electric fan;
- a compressor including a motor having first and second terminals, the first terminal being connected to one of the first and second terminals of said electric fan;
- a condenser coupled to said compressor;
- an evaporator coupled to said compressor and said condensor;
- a thermostat controlled switch connected between the second terminal of said compressor motor and the other one of the first and second terminals of said electric fan;
- and
- a switch means for periodically providing a conductive path between the second terminal of said compressor motor and the other one of said first and second terminals of said electric fan.
A method of operating a dehumidifier having a fan, a compressor, an evaporator coil, a condenser coil and a humidistat switch for activating the dehumidifier when the ambient humidity is above a preselected level, said method comprising:
- periodically stopping the operation of the compressor for a given interval when the ambient temperature is below a given value;
- and
- operating the fan during the given interval.
