ABSTRACT:
An improved thermal control system for flight apparel worn in an aircraft. An environmental control system (11) produces both a flow of cold air in a duct (12) and a flow of warm air in another duct (14). A mixing chamber (16) is connected to both ducts (12, 14) and mixes the flows of cold and warm air received therefrom to produce a flow of personal conditioning air. A valve (32), positioned in the warm air duct (14), controls the amount of warm air flowing into the chamber (16). The valve (32) is operated to adjust the mixing of warm air with cold air in the chamber (16), to thereby adjust the temperature of the personal conditioning air so that it is at a temperature which is comfortable. A comfortable temperature is selected by a control switch (28). The valve (32) is continuously adjusted in accordance with temperature signals received from a temperature sensor (30). A controller minimizes the error between the temperature served by the sensor (30) and the temperature selected by the control switch (28). The personal conditioning air is delivered to flight apparel by means of a personal air conditioning conduit (20).
