所有冷冻压缩机的运转均可产生无谓的内部能量损失。这些损失一般都与内部能量和总的压缩过程中产生的气体传递过程有关。对包括回转滑片压缩机在内的上述的研究指出.内泄漏气体传递是一种相当大的损失过程。内部泄漏因降低了在排气压力和排温时气体的排量,故降低了容积效率。就降低冷却效率而言,只要降低压缩机内的冷冻剂量即能影响压缩机的性能参数。研制效率更高的压缩机必须弄清内泄漏的机理,并对其进行计算。 All refrigeration compressors operate with insignificant internal energy losses. These losses are generally related to the internal energy and the process of gas transfer generated during the overall compression. The above studies, including rotary vane compressors, indicate that internal leakage gas delivery is a relatively large loss process. The internal leakage reduces the volumetric efficiency by reducing the gas displacement during exhaust pressure and exhaust temperature. To reduce the cooling efficiency, as long as the amount of refrigerant in the compressor can reduce the compressor performance parameters. Developing a more efficient compressor must understand the mechanism of internal leakage and calculate it.
