According to the present invention, a cooling and heating device for an aircraft is constructed to use condensate water created by an evaporator in pre-cooling air to lower the condensation temperature of a condenser to improve the performance coefficient of a cooling and heating device. In addition, condensate water discharged from the condenser after pre-cooling air is circulated back to an evaporator condensate water tank to be reused to easily secure the flow of condensate water and improve the use effect of condensate water. Moreover, the condensate water discharged from the condenser after pre-cooling air is circulated to the evaporator condensate water tank, is discharged to the outside, or is directly supplied to a condensate water supply flow path in accordance with the temperature of the condensate water to effectively use the condensate water. In addition, according to the present invention, the cooling and heating device for an aircraft efficiently arranges a plurality of compressors, a plurality of condensers, a turbo intake fan, an evaporator, etc., when realizing a compact device with high energy efficiency.

    본 발명에 따른 항공기용 냉난방 장치는, 증발기에서 생성된 응축수를 응축기에서 공기를 예냉하는데 활용하도록 구성됨으로써, 응축기의 응축 온도를 하강시켜 냉난방 장치의 성능 계수를 향상시킬 수 있다. 또한, 응축기에서 공기를 예냉하고 나온 응축수를 증발기 응축수 탱크로 다시 순환시켜 재사용함으로써, 응축수의 유량 확보가 용이하면서도 응축수의 활용 효과가 향상될 수 있다. 또한, 응축기에서 공기를 예냉하고 나온 응축수의 온도에 따라 증발기 응축수 탱크로 순환시키거나 외부로 배출시키거나 응축수 공급유로로 바로 공급하도록 구성됨으로써, 응축수를 보다 효율적으로 활용가능한 이점이 있다. 또한, 본 발명에 따른 항공기용 냉난방 장치는 케이스의 내부에 복수의 압축기들, 복수의 응축기들, 터보 흡기팬 및 증발기 등을 효율적으로 배치함으로써, 컴팩트하면서도 에너지 효율이 높은 장치를 구현할 수 있다.
