1. An environmental control device for an aircraft, the environmental control device comprising:
a motor;
a shaft coupled to the motor, wherein the motor is configured to rotate the shaft;
a compressor connected to the shaft, wherein the compressor is configured to compress external air introduced into the aircraft to form a flow of compressed air having a raised temperature;
a heat exchanger configured to allow a heat exchange between the compressed air having the raised temperature and a portion of additional external air introduced into the aircraft; and
a turbine coupled to the shaft, wherein the turbine is configured to expand the heat-exchanged compressed air to form a flow of chilling air, wherein:
a first introduction line, connecting a first air scoop and an interior space of the aircraft, and a second introduction line, connecting the first air scoop and the heat exchanger, are branched from a first external air line forming a flow path from the first air scoop to the compressor,
a first heating line is connected to the second introduction line downstream of the heat exchanger, and
a heating heat exchanger is disposed between the first heating line and the first introduction line.
