| Abstract: |
| An aircraft’s environment control system provides the proper environment for its safe and stable flying. The refrigeration and air-conditioning systems are the core parts of an aircraft. The functional requirements, thermodynamic principles and system processes of refrigeration and air-conditioning systems are introduced. Air compression refrigeration cycles (such as basic cycle, two-wheel booster refrigeration cycle, three-wheel booster refrigeration cycle, four-wheel booster refrigeration cycle, and reverse booster refrigeration cycle), vapor compression refrigeration cycles, and combined refrigeration cycles are compared. The advantages and disadvantages of high-pressure water separator and low-pressure water separator are also discussed. Advanced refrigeration and air-conditioning technologies, such as thermos-electric refrigeration system, pneumatic control, humidifying technology, loop heat pipe, etc. are also introduced. Research directions and key technologies for the future are summarized. |
