The invention belongs to the technical field of airborne environmental control/thermal management. Relates to a helicopter evaporation cycle refrigeration system and a control method. The system comprises a refrigeration assembly, a heat source assembly, a hot air collection assembly and a refrigeration control box. Stable control over the condensation temperature is achieved by controlling the air volume of a condensation fan and the hot air flow of a lubricating oil radiator, the temperature of the wall face of an evaporator is made to be above the defrosting temperature all the time, frequent defrosting of a high-altitude flight refrigerating system is effectively avoided, and the flight efficiency is improved; by recycling lubricating oil waste heat to preheat the atmosphere outside the cabin, the defrosting frequency of a refrigerating system can be reduced, even defrosting is avoided, efficient work of a pilot is guaranteed, and the flight efficiency is improved.
本发明属于机载环控/热管理技术领域。涉及一种直升机蒸发循环制冷系统及控制方法。系统包括制冷组件、热源组件、热风收集组件、制冷控制盒;通过控冷凝风机风量和滑油散热器热空气流量,实现冷凝温度稳定控制,使蒸发器壁面温度始终在除霜温度以上,有效避免高空飞行制冷系统频繁除霜,提高飞行效率:直升机飞行高度时刻变化,舱外大气温度也随之变化,通过回收滑油废热预热舱外大气,可以减少制冷系统除霜次数,甚至避免除霜,保障飞行员高效工作,提高飞行效率。
