Automatic temperature and humidity regulating apparatus

摘要

The present invention relates to an automatic temperture and humidity regulating apparatus for indoor air comprising (1) a heat exchanger (2) a constant flow valve device being so associated and constituted that a differential pressure regulating valve having a diaphragm is connected to an inlet side of the heat exchanger and that a temperature compensating valve having a characteristic to pass a desired flow at its fixed rate by self-regulation of the degree of valve opening in sensing temperature variation through a temperature sensing sleeve is connected to an outlet side of the heat exchanger whereby pressure of the downstream side of the outlet of the temperature compensating valve is fed back to the differential pressure regulating valve as a signal pressure and (3) a humidity regulating valve providing a humidity detecting body disposed in a ventilating passage of the heat exchanger.
