Abstract

Currently, global warming is considered one of the main environmental problems in the world today. Air conditioners are among one of the major causes of global warming. Producing environmental friendly equipment that can provide cool air would be helpful. One idea is a combined system between an evaporative cooling system and a thermoelectric device (with heat sink). This combined system provides temperatures and relative humidity in a comfort zone. However, the efficiency is slightly lower when compared with conventional air conditioning. This project tries to improve both the evaporative cooling and thermoelectric system. In an evaporative cooling system, the shape of the material is important because it can increase the surface contact area between the air and water. However, the life of the material also needs to be considered. For a thermoelectric system, by improving the efficiency of the heat sink, it will increase the efficiency of the whole system. The basic idea of this combined system is that the hot air is added to the evaporative cooling system which decreases the air’s temperature while increasing the relative humidity. Then the air passes through the thermoelectric cooling system, to further decrease the air’s temperature, reducing relative humidity. The cooling capacity of the system can be increased by adjusting the thermoelectric current
