EVALUATING AN ALTERNATIVE COOLING SYSTEM FOR THE TRACTOR CABIN

The cooling system in the tractors cabin consumes a significant power from the engine, besides it has a bad effect of gases on the environment, moreover it requires maintenance. The alternative cooling system that developed in this study depends on its work on the principle of Peltier effect by using Thermo-Electric Cooling system (TEC). The study includes two factors first is the fan speeds for air flow (1.2, 3.6)m\s and second is three levels of thermoelectric cooling unit (TEC) namely 2, 4, 6 units. The investigated properties in this study were: the temperature difference (Delta T) between driver's cabin and ambient, cooling load (Qc) and coefficient of performance (COP). The results showed that decreasing the fan speed had a significant effect on the studied parameters. Using six units of TEC resulted in an increase in the difference between driver's cabin and ambient, cooling load and coefficient of performance (COP).
