Abstract
The airborne high power electrical equipments have been widely used in modern aircrafts, which consequently causes the dramatic increase of heating load up to dozens of kilowatts. Accordingly, vapor-compression refrigeration system (VCRS) with lower engine bleed air and larger refrigeration capacity has been paid much attention in recent years. Therefore, based on the analysis of the characteristics of VCRS, an experiment system of VCRS using R134a is set up to simulate operation performances. The influences of different parameters including evaporation pressure, condensing pressure, refrigerant mass flow rate and compressor rotation speed are also investigated. The impacts of different parameters on the system performance are various. This work can help to establish the specific control law under different work conditions.
