REFRIGERATION AND AIR CONDITIONING 1. DEFINATION OF REFRIGERATION Refrigeration is defined as “ the branch of science that deal with the process of reducing and maintaining the temperature of confined space or material below the temperature of surrounding” the system maintain at lower temperature is known as refrigerated system and equipment used to obtain this is known as refrigerator. The cooling effect produced by this equipment is the refrigerating effect. 2. PRINCIPLE OF REFRIGERATION

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

Multimedia Compression techniques 4.0 Introduction In this unit we are discussing about the data compression which is very important for multimedia applications because uncompressed graphics‚ audio‚ and video data require considerable storage capacity. Compressing a data file reduces its size‚ and hence it can be easily transferred over the digital network. The amount of compression depends on the compression method and compression rate. The terms compression

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

ABSTRACT The requirement that no information be lost in the compression process puts a limit on the amount of compression we can obtain. The lowest number of bits per sample is the entropy of the source. This is a quantity over which we generally have no control. In many applications this requirement of no loss is excessive. For example‚ there is high frequency information in an image which cannot be perceived by the human visual system. It makes no sense to preserve this information for images that
