Dynamic numerical investigation of airborne vapor cycle cooling system

With the increasing power of airborne equipment, the airborne thermal management technology has been paid more and more attention. Because of its high COP value and high refrigeration capacity, vapor cycle cooling occupies an important position in active thermal management technology. This article mainly calculated vapor cycle cooling system as a model. Evaporator, condenser, compressor, electronic expansion valve and flight environment model are set up in AMEsim software. A dual control strategy is established to meet the requirements of external complex flight conditions by using the supercooling of condenser and the superheat of evaporator outlet as the objective function. Based on the change of the power demand of typical flight envelope and electronic equipment of a certain type of aircraft, the dynamic performance simulation study of the airborne vapor refrigeration cycle was carried out. The dynamic simulation results can provides guide for designing the airborne vapor cooling cycle.
