التحليل الطاقي لدارة تبريد ثنائية المرحلة في معمل البان دمشق

The main objective of this paper is to analyze the energy performance of a two-stage refrigeration system at Dairy Factory at Damascus and define the losses in each element of the station in order to pinpoint the most energy inefficient part. We have worked on eliminating the losses and increased the Coefficient of Performance (COP) of the two-stage cycle and reduced the energy consumption in the system. We have put together a method to compute the COP and Exergy and compare the results with a home-made program based on the previous method. We have concluded that the compressor was the most energy consuming device, evaporator second and condenser third. We have recommended practical solutions for the losses in the system.
