Abstract

The analysis of change of refrigerating of АRМ is carried out at use for overcooling of liquid ammonia of reversible cycles, and also the compressor refrigerating machine working on R134a. A values of optimum temperatures of overcooling of ammonia before throttling, answering to maximum of refrigerating efficiency of АRМ are found. It is offered to use for overcooling of ammonia in a range from 30 °С up to 7 °С the absorption lithium bromide refrigerating machine, and from 7 °С up to –10 °С — the compressor refrigerating machine. The refrigerating efficiency of such combined ammoniac refrigerating machine will be raised on 12,6 %.
