Abstract:
This report presents a study on development and analysis of double effect condensing unit vapor compression refrigeration system (DECU VCR system). The system is composed by two refrigeration cycles working with R134a. Tests under a wide range operating temperature interval conditions were carried out on the developed system. Experimental data was generated to observe the performance of the basic VCR system and DECU VCR system for an important parameters such as condensation (35 to 55°C) and evaporation temperatures (-5 to 15°C). Performance evaluation of the system was characterized in terms of cooling capacity and coefficient of performance (COP). In the present study, both COP and refrigerating effect of the developed system have been found, in general, to be greater than the corresponding basic VCR system values, but the degree of enhancement varies depending on the test conditions. Additionally, by using dedicated sub-cooling cycle, up to 11 and 11.7 % performance improvement ratio of VCR system are observed at evaporation temperature of 15 oC and condensation temperature of 35 oC respectively. It can be concluded that the use of dedicated sub cooling cycle in VCR system is most efficient and suitable for the betterment of thermal system performance.
