摘要
Two generation miniature Wankel compressors with the cooling capacity of 300 W were developed. The weight of first generation compressor is 700 g and that of second generation is 400 g. A miniature spiral-tube type evaporator is developed which weighs 0.26 kg and a brazed aluminum multi-channel parallel type condenser is also developed which weighs 0.3 kg. Based on the development of above components, a miniature refrigeration system prototype with a cooling capacity of 300 W was integrated and the system weighs about 2.85 kg. An experimental system for miniature refrigeration system was set up. The tests of the performance of miniature refrigeration system were done. The experimental results indicated that the compression ratio of the compressor is above 3.0, the refrigerating output of the system is above 300 W and the coefficient of performance of the developed micro climate cooling system was about 2.3.
