Abstract
PURPOSE: To enable to control feeding and discharging proper and necessary volumes of air automatically by securing a supply of air consumed by a specimen in a chamber and a ventilating air necessary for workmen in the chamber under keeping a pressure in the environmental test chamber.
CONSTITUTION: When an air volume consumed by a specimen 2 installed in an environmental test chamber is less than a ventilating air volume necessary for workmen, a control valve 3 for feeding air inputs a signal from a transmitter 5 for controlling ventilated volume by an operation of a signal switching device 7 and a control valve 4 for discharging air inputs a signal from a transmitter 6 for controlling indoor pressure by an operation of a signal switching device 8. When the air volume consumed by the specimen 2 is increased, the control valve 4 for discharging air is closed and the signal from the transmitter 6 for controlling the indoor pressure is interrupted by the signal switching device 8, while, the control valve 3 for feeding air is interrupted from the signal of the transmitter 5 by the operation of the signal switch in device 7 and inputs the signal from the transmitter 6 for controlling the indoor pressure, thereby, a control for feeding air of which volume is corresponding to the air volume consumed by the specimen 2 is effected.
