APPARATUS FOR CONTROLLING TEMPERATURE AND PRESSURE OF AIRCRAFT

An apparatus for controlling temperature and pressure may include: a shaft (10) installed in an aircraft, the shaft (10) being rotatable by having a motor (11) coupled thereto; a compressor (20), rotatable by being connected to the shaft (10), configured to form a flow of heated compressed air by compressing external air introduced into the aircraft; a heat exchanger (30) configured to heat-exchange the heated compressed air with a portion of external air introduced into the aircraft; a turbine (40), rotatable by being connected to the shaft (10), configured to form a flow of cooling air by expanding the heat-exchanged compressed air; and a cooling heat exchanger (50) configured to exchange heat between a refrigerant cooling a fuel cell power train (5) in the aircraft and the cooling air.
