Abstract : Article presents the results of an experimental investigation carried out to minimize the power consumption of a solar cooler running at various speeds. The experiments have been carried out for a total of three speeds that is low, medium and high. Speed was control by minimizing the input current at multiple levels with the help of resistors. For high speed, unit has connected to couple of resistors in series, whereas for medium speed couple of resistors were connected in parallel and for low speed a single resistor was used. DC motor in traditional coolers got replaced with Permanent Magnet DC motor. PM DC motor is highly efficient since no electrical energy is used or losses incurred for developing or maintaining motor’s magnetic field. Its size is more compact and a better dynamic performance can be expected due to higher magnetic flux density in air gap.PM DC motor has an essentially simplified construction and it is maintenance free, in addition cotton was included in cooler setup. Water is made to flow from a higher potential to lower potential making the grass and cotton wet. Even if the potential of water becomes lower, it does not create any hindrance to the function of cooler. Elimination of pump reduces the expenses in addition to lowering the overheads caused while lifting the water.
