ABSTRACT:

Vapour Absorption Refrigeration Systems (VARS) and vapour compression refrigeration system (VCRS) both are widely used for refrigeration purpose. The major differences in both the system are in vapour compression refrigeration systems the input supply is compressor work which is high grade of energy whereas in vapour absorption systems main input is heat supply in the generator which is low grade energy. Energy is an essential requirement for the economic development of any country, so our main aim is to save energy, unless VCRS have high performance future scope is VARS are primarily used in large commercial and industrial installations .In this paper discusses the various methods for increasing the performance of both systems so this paper focuses on the suitability of both systems. Keywords: Refrigeration, Coefficient of Performance, Vapour Absorption Refrigeration System, Vapour Compression Refrigeration System.

range of temperature for high coefficient of performance. In this system the low pressure temperature of the vapour refrigerant is enters into the compressor through the inlet valve where it’s compressed to a high temperature and pressure and this refrigerant is discharge into the condenser where heat is removed. An automatic expansion valve is used for reducing the pressure and this low pressure refrigerant enters into the evaporator [4].

1. INTRODUCTION 1.1. Vapour compression refrigeration system (VCRS). When the term “refrigeration” comes we make up the mind about refrigerator that works on the electrical supply and provides us cooling, ice and preserves our beverages and food items from getting exhausted. In these types of refrigerators the components that are used are compressor, condenser, and evaporator and expansion valves. Basic principle taken from first and second law of thermodynamics .This system would have wide IDL - International Digital Library
