dc.description.abstract | The work we are introducing concerns the study of the performance of the single acting compression trans-critical machine operating with𝑅744 as refrigerant. A comparative study of the trans-critical cycle at 𝑅744 and of the classical cycle working with 𝑅134𝑎is made. The work is carried out with the “Cool Pack” software after a thermodynamic analysis of the cycles concerned. This work allowed us to determine the thermodynamic characteristics of the trans-critical cycle, among which an essential factor is the coefficient of performance “COP”, and to improve the trans-critical cycle by adding a heat exchanger, in order to increase cooling efficiency. Therefore, it is proposed to use the trans-critical machine running on 𝑅744 in the industrial field, specifically the pharmaceutical industry because this fluid is not harmful to the environment and economical | en_US |
