Abstract
This study conducts an experimental analysis of a vapor compression refrigeration system (VCRS) test rig on the basis of first and second laws of thermodynamics. Performance analysis of the VCRS was conducted in winter and summer climatic conditions. The results show that high coefficient of performance (COP) is achieved in winter under both first and second law of thermodynamics analysis.

Summary
Despite the high dependence of the coefficient of performance (COP) of vapor compression refrigeration systems (VCRS) on weather conditions, very little research is done to qualitatively and quantitatively analyze this dependence. Winter conditions do not require the same refrigeration effect like summers, but power and energy are still required for the system performance and its utilization in efficient manner. As a large amount of heat is transferred between various thermal utilities and greatly affects the overall system performance, an in-depth understanding of energy consumption dynamics in cooling and refrigeration systems is important in a world facing climate change. The main objective of this paper is to compare the performance indicators of VCRS in summer and winter conditions. It presents the results of an experimental analysis of a 1 ton of refrigeration (TR) VCRS test rig based on first and second laws of thermodynamics in winter and summer climatic conditions of northern India. The first law of thermodynamics deals with quantitative approach of energy and its conversion as per requirement, whereas the second law of thermodynamics speaks about actual useful energy supply and allocation of energy losses in the system through exergy analysis
