Popis: | This paper provides the results of a performance analysis of a two-stage mechanical compression–ejector cooling cycle. In the proposed cooling system the compression process is realized in two stages: by a mechanical compressor as the first stage and by an ejector as the second stage. Ammonia (R717) is investigated as the working fluid for the cooling system in the present study. The influence of the middle pressure, and evaporating and condensing temperatures on the characteristics of the cooling system is analyzed. Based on the obtained results a pilot small-scale two-stage refrigeration unit with cooling capacity of 10 kW intended for application in micro-trigeneration systems is designed. |
