Design and Fabrication of Thermo Electric Air-Cooler

Cooling may be defined as the process of achieving and maintaining a temperature below that of surrounding. Natural air cooler is available at low cost but the temperature reduced by that is very less. To get high reduction in temperature air conditioner is used. In regular air conditioning process the refrigerants used may cause environmental pollution because of production of CFC's, may cause health problems such as dizziness, headaches, irritation to eyes and other environmental effects. To reduce the environmental pollution and to obtain effective cooling as that of normal air conditioners, we bring up a new type of cooling method that is thermo-electric cooler using thermo electric cooling modules with no moving parts as in air-conditioners and without chlorofluorocarbons. The main objective of the present work is to design and fabricate thermoelectric air cooler in which water of 4.5 liters is used to cool air and produce cooling effect. It works with ample amount of power supply. The desired design is intended to provide a good alternative to Air Conditioners which consume sufficiently high power with very large initial investment. We can extend this design to commercial purpose by increasing the capacity of thermoelectric modules and size of equipment.
