INTRODUCTION Vapour absorption refrigeration system is one of the oldest methods of producing refrigerating effect. John Leslie in 1810 kept H2SO4 and water in two separate jars connected together. H2SO4 has very high affinity for water. It absorbs water vapour and this becomes the principle of removing the evaporated water vapour requiring no compressor or pump. H2SO4 is an absorbent in this system that has to be recycled by heating to get rid of the absorbed water vapour‚ for continuous operation

Methods to meet this goal will differ depending on the size of aircraft‚ due to the changing volume of airflow there several way for air condition system for a aircraft. The best choice for small aircraft vapour cycle cooling system(VCCS) been used. Vapour cycle refrigeration is the predominant means of air-conditioning in small - and medium-size business aircraft and helicopters. Vapour cycle cooling system (VCCS) is more easier to used on small

THE REFRIGERATION SYSTEM AN INTRODUCTION TO REFRIGERATION APPLICATION NOTE BASIC REFRIGERATION PRINCIPLES If you were to place a hot cup of coffee on a table and leave it for a while‚ the heat in the coffee would be transferred to the materials in contact with the coffee‚ i.e. the cup‚ the table and the surrounding air. As the heat is transferred‚ the coffee in time cools. Using the same principle‚ refrigeration works by removing heat from a product and transferring that heat to the outside air
