【 摘 要 】

The air-conditioning system of electric vehicles shortens the driving mileage of the car. Therefore, a set of absorption-compression hybrid refrigeration system for hybrid electric vehicle are designed. The system consists of power system, absorption refrigeration cycle and compression refrigeration cycle. By using the waste heat of micro gas turbine to drive the absorption refrigeration subsystem, the power consumption of the compressor driven by battery power is reduced, as well. The feasibility of the system is discussed through the thermodynamic cycle calculation. The results show that, a bus air-conditioning with cooling load of 30 kW, the waste heat emitted by a micro gas turbine with a power of 35 kW drives an absorption refrigeration cycle, which can provide about 15 kW of cooling capacity, and the remaining part needs to be compensated by the compression refrigeration cycle, which consumes about 6.71 kW of compressor power. At the same time, compared with the absorption-compression combined refrigeration and electric compression refrigeration, the energy efficiency is improved by about 37.1 %.
