The invention is an energy-efficient all-electric environmental control system (70). The system includes a cabin compressor (16) and a Freon compressor (14), both of which are commonly driven by a two-speed electric motor (12). The motor (12) operates at low speed at low altitudes and on the ground to drive the Freon compressor (14). Freon fluid then cools the electric motor (12) and the cabin (18) and avionics (56) by means of the evaporator/dehumidifier systems (72) and (74), respectively. At high altitudes the electric motor (12) runs at high speed to...
In an aircraft environmental control system having an air cycle cooling system powered by an electrical motor and, an evaporative cooling sub-system coupled thereto, said cooling sub-system having a cooling circuit including fluid coolant, at least one coolant compressor coupled to said electric motor, and at least one coolant expansion means the improvement comprising: means to selectively disconnect said coolant compressor from said electric motor; said air cycle cooling system having means to bypass said at least one coolant expansion means and said a...
