ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to an air conditioning device. More particularly, the invention relates to an air conditioning device which has a by-path damper.
Referring to
FIGS. 1
to
3
, a conventional air conditioning device has a fan motor
71
, a heat exchanger
72
, and a control electric circuit
73
. The variation speeds of the conventional air conditioning device have three steps only, such as a full speed, a middle speed, and a low speed. However, the three step adjustment of the conventional air conditioning device will cause a large fluctuation of room temperatures.
SUMMARY OF THE INVENTION
An object of the invention is to provide an air conditioning device which can save energy efficiently.
Another object of the invention is to provide an air conditioning device which has an efficient by-pass damper to adjust the amount of air condition auto-matically.
Accordingly, an air conditioning device comprises a controller, a fan motor, a by-pass damper, and a heat exchanger. The fan motor is disposed in front of the heat exchanger. The by-pass damper is disposed between the fan motor and the heat exchanger. The controller controls the by-pass damper. The controller has a central processing unit, an output control unit, a detect unit, and a sensor. The sensor senses an environmental detect value to the detect unit. The detect unit outputs the environmental detect value to the central processing unit. The central processing unit outputs a signal to the output control unit. The output control unit has a plurality of output junctions connected to a loading unit.
