IMPROVING THE PERFORMANCE OF VAPOUR COMPRESSION REFRIGERATION SYSTEM USING MAGNETIC FIELD

This Project presents experimental investigations carried out to study the effect of magnetic field on energy savings in vapor compression system. Application of magnetic field to fluid flow breaks the molecule resulting in a decrease in the viscosity of the fluid. This drop in the viscosity reduces the pumping power required by the compressor as well as enhances the heat transfer rates in the condenser and evaporator due to increased mass flow rates. The net impact is improvement in the COP of the system. Considering the number of refrigerators and air conditioning systems sold globally every year any improvement in the COP could considerably save the energy bills as well as the energy requirement. The main benefit of this investigation is improvement in the system performance, improvement in Evaporator capacity or drops in compressor power or increased COP at no cost i.e. no additional input energy. Only cost involved is the initial cost of magnets to be procured for applying suitable magnetic field. The present work was focuses on establishing the effect of magnetic field on the performance of the vapour compression system. The magnetic field strength was varied by increasing the number of magnet pairs applied to the liquid line (from condenser outlet to entry of expansion valve). The COP is initially measured without application of magnetic field, and then magnetic field is applied to liquid line by increasing the number of the magnets. The result will be assessed for increasing the COP of the system.
