Abstract

PURPOSE: To control humidity in response to the seasons of the winter season, the rainy season, the summer season, etc. by means of one humidity sensor, by switching an air conditioner and a humidifier ON-OFF by the results of comparison between the output of the humidity sensor and the reference signal.
CONSTITUTION: When dehumidification, interlock switches 6, 7 are connected as shown in the figure, and voltage Vh detected by means of a humidity detecting sensor 9 is compared with the reference voltage Vref by means of a comparator 13. When Vh>Vref, and output level of the comparator becomes to a H level, and a transistor 16 is in ON. Thus, current flows through a relay coil 18, a switch 4 is in ON and a dehumidifier 2 starts its operation. When dehumidification advances and detecting voltage Vh lowers, a voltage level of the comparator 13 becomes to a L level, the transistor 16 is in OFF and the dehumidifier 2 stops its operation. Feedback is applied to the comparator 13 by a resistance 14, and the output voltage of the comparator 13 is provided with hysteresis characteristic.
