AI Technical Summary
The evaporative cycle cooling engine bleed air heating air conditioning system of the basic trainer aircraft cannot provide lubricating oil heat on the turboprop engine, resulting in reduced engine reliability. In addition, the existing system has a low coefficient of performance (COP) and cannot meet the special operating requirements of the trainer aircraft.
An evaporative cycle refrigeration engine bleed air heating air conditioning system was designed, including a bleed air module, a ventilation and heat exchange module, a compressor and a cooler module. Through conformal design and air path switching, the system achieves temperature control and defrosting functions in the cockpit. Electromagnetic shut-off valves and pressure regulating valves are used for gas handling to enhance system reliability and heat dissipation.
The improved coefficient of performance (COP) enhances the system's reliability and heat dissipation, enabling ground-based cooling, reducing the impact of solar radiation on the cockpit, and meeting the temperature control requirements of the trainer aircraft.
