Small-size and light-weight environmental control unit for aircraft-external stores

A small-size and light-weight environmental control apparatus for aircraft-external stores, the environmental control apparatus supplying a constant temperature environment to an image information acquisition apparatus provided in a pod of aircraft and comprising:

• (A) a condensation air flow loop 10 in which a ground fan 12 driven when the aircraft is moved on a ground or a ram air scoop 11 driven when the aircraft flies performs a thermal exchange with a condenser forming a cooling/heating flow loop 20;
• (B) the cooling/heating flow loop 20, including an evaporator 21 configured to absorb surrounding evaporation heat by evaporating the refrigerant, a compressor 23 configured to have a rotating shaft coupled to a shaft of a ram air turbine, a condenser 27 configured to perform a thermal exchange by the condensation air flow loop, and an expansion valve 28 configured to expand the refrigerant condensed by the condenser, wherein the evaporator, the compressor, the condenser, and the expansion valve are interconnected by a refrigerant circulation line RL;
• (C) an air circulation loop 30 for circulating and supplying cooled or heated air to a camera/electronic unit 31 so that the camera/electronic unit 31 maintains a constant temperature;
• and
• (D) a controller 40 for controlling a driving of the constituent elements in each of the loops.
