摘要
通过两种相似换算方法,把以R134a为介质时的工况点换算到以空气为介质时的对应工况点,换算结果和试验数据比较,得出保持进口比容比相等的换算方法更加准确,与试验结果吻合良好。
One centrifugal compressor is used for refrigeration and its working substance is R134a.The operating points are obtained when the working substance is air by using two similar conversion methods from the operating points when the working substance is R134a.By comparing with test result,it can be obtained that the result of keeping the specific volume ratio of inlet is more accurate and keep consistent well with test results.
