Vapour-Compression Refrigeration Experiment Thermodynamics Date of experiment: 26 June 2012 Group D2: Introduction The laboratory session for refrigeration system was performed in order to investigate the main concepts of the vapour-compression refrigeration cycle. Simple refrigeration system studied in the laboratory is a prototype for a variety of engineering applications utilized in industrial‚ domestic and scientific purposes. The detailed goals include the study of how the refrigeration process is

The Refrigeration Process Refrigeration has probably been around longer than you think. In 1823‚ Michael Faraday discovered that certain gases under constant pressure will condense when they cool. In 1875‚ Raoul Picet used sulfur dioxide as a refrigerant and in 1931 Refrigerant R-12 was developed by Thomas Midgley and C. F. Kettering. The Kelvinator refrigeration unit‚ ice cream units‚ and Semi-hermetic compressors were introduced at the beginning of the 20th century. In this

MAGNETIC MAGNETIC REFRIGERATION a fruitful approach to reduce environmental pollution... ABSTRACT : The objective of this effort is to determine the feasibility of designing‚ fabricating and testing a sensor cooler‚ which uses solid materials as the refrigerant. These materials demonstrate the unique property known as the magneto caloric effect‚ which means that they increase and decrease in temperature when magnetized/demagnetized. This effect has been observed for many years and was used for cooling

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
