    • 4.5    CAPILLARY TUBE
      The capillary tube is a mating device which aidto metal the flowquid horn the condenser to the evaporator. It Operate or the principle that a given weight of a liquid will pass through the capillary rube more readily than the same weight of gas will do at the same pressure Hence, immediately the condensed refrigerant vapour enter the capillary tube, the mass flow refrigerant will be reduced there by cooling time in the compressor, the condensing temperature in pressure will rise, giving rise to air increase in the mass flow of the refrigerant.
      The advantage of capillary tube are listed below
      1.    It is simplicity which makes it not be required any moving part.
      2.    It enable pressure to equalize the system during of cycle and reduce the starting forgone required by the compressor motor.
      The ease with which it can be silvered to the suction line for it exchange purpose there by eliminating wearing of otherwise cold suction line and at the same time affecting capacity.
      4.6    STRAINER DRIER
      At strainer is used for removing foreign materials and dirt from the refrigerant, so they will not be able to cause damage to the compressor values and controlling devices in the refrigerating system, the strainerinform of a very fine tube filter. They are usually in mesh which range from 70 to 100 meshes William, (2005). The are used to absorbed moisture content from the refrigerant, it consist of a decent which is made of silicagel, a material that has the ability to absorb any acid already formed and has a great affinity for moisture. These descants are made such that do not react with the refrigerant non soluble in it. The combination of stainer drier is normally located directly ahead of the capacity to protect it against ice plugged or any foreign material circulating through the system.

    • ABSRACT - [ Total Page(s): 1 ]ABSTRACTThis paper describes the quick and precise control method for domestic refrigerator. The propose controller is based on the fuzzy logic and neutral network designed maintaining the constant inner temperature (of the refrigerator and improving the refrigerator efficiency. The fuzzy logic controller is used to maintain the inner temperature inspite of the environment variation such as outer temperature change of the volume change of the stored food to the refrigerator a neutral network is ...

      CHAPTER TWO - [ Total Page(s): 2 ]CHAPTER TWO2.1    LITERATURE REVIEWRefrigeration is the branch of engineering that is concern with the producing and maintaining temperature below that of the surrounding atmosphere .this implies the development of temperature differential rather than the establishment of a given temperature level. The act was known to the ancient Egyptians and the people of Indian, who use evaporation to cool liquid in porous earthen jar exposed to dry night air, and to the early Chinese, Greeks and Romans w ...
