Abstract

PURPOSE: To enable humidity control with high accuracy, by constituting the bridge circuit having the heat sensing element to detect the temperature of dry and wet bulbs as one side and automatically adjusting the air in-take and discharge in response to the temperature difference between the dry and wet bulbs.
CONSTITUTION: The wet temperature bridge circuit 8 consists of the wet bulb temperature sensor 1 using heat sensing element such as thermister, dry temperature sensor 2, variable resistor 3, and resistor 4, the dry bulb temperature bridge circuit 8 consists of the sensor 2, resistors 4 and 7, and variable resistor 6. The resistor 6 is made variable, and if the balance of the circuit 8 is unbalanced, the burner 22 is ignited via the amplifier 18, transistor Tr20, and relay 21 and when the circuit 8 is balanced with increased temperature, the burner is distinguished. If the temperature difference of the circuit 5 balanced with a given temperature difference of dry and wet bulbs exceeds a given value, the motor 13 is activated via the amplifier 9, Tr11, and relay 12 and control is made to obtain constant humidity by controlling the in-take and exhaust 16, 17.
