Abstract

PROBLEM TO BE SOLVED: To provide a natural vaporization type humidifier equipped with an air-conditioner without using any electric part by providing a water feed valve to open through operation of a thermally-actuating device when the temperature of heated air exceeds a prescribed value and close when it is below the prescribed value. SOLUTION: A water feed valve 23 is opened through operation of a thermally-actuating device 22 when the temperature of air flowing through a heat-exchanger 4 is increased to a prescribed value and closed when it is below the given value. When a wax thermo is used as the thermally-actuating device 22, the wax thermo is expanded and a spindle 22-1 is advanced. When the temperature of air flowing through the heat-exchanger 4 is increased to a prescribed value, an valve element 28 is pressed down against urging of a spring 29 and the water feed valve 23 is opened. When the wax thermo is contracted and the spindle 22-1 is moved backward, the water feed valve 23 is closed through urging of the spring 29. This constitution eliminates a fear of leak occurring and dissolves a problem on malfunction due to the error of wiring.

When the air flowing through the heat exchanger 4 rises to a predetermined temperature while the air conditioner is heating, the water supply valve is opened by the operation of the heat responsive device, and the humidifying water is supplied to the humidifying element 6. Then, the humidifying element 6 is moistened, the heated air is blown to evaporate the humidified water, and the heated air is humidified. When the heating stops, the temperature of the air passing through the heat exchanger decreases, and the operation of the heat responsive device closes the water supply valve, thereby stopping the supply of the humidifying water to the humidifying element 6. When the air conditioner is performing cooling, the temperature of the air passing through the heat exchanger 4 is low, so that the operation of the heat responsive device does not open the water supply valve.
