To develop the production of domestic refrigeration units, it is necessary to develop a line of rotary refrigeration compressors, and for each compressor model it is necessary to calculate the field of operating parameters that it can provide for various refrigerants. One of the reasons that worsen the energy performance of rotary compressors is the flow of gas from one cavity to another through various leaks. Gas leaks through gap reduce the compressor performance and increase the specific indicator work. It is not possible to reduce the gaps for design reasons. Therefore, when designing, it is necessary to know where leaks can occur and be able to calculate them. Until now, this problem has no unambiguous solution. To perform parametric analysis of the compressor, it is necessary to develop a universal technique that allows both design and verification calculations and to develop a calculation program. This article is devoted to the development of a calculation technique for rotary refrigeration compressors using mathematical modeling methods.
