Model development of refrigerator and heater based on Peltier module and Fresnel lens

Energy crisis has always been a major issue for the world. As energy demand is escalating day by day, everyone necessitate appliances that use less amount of energy because conventional appliances i.e. refrigerators and heaters consume large amount of power ranging from 200W to 1500W. Proposed model is based on Peltier effect, and uses Peltier module (TEC1-12706) which exhibit cooling at one side plate and heating on other one depending upon supply voltage biasing. For improving heating effectiveness Fresnel lens heat collector concept is also used. So in energy saving context, a model is proposed which can be used for heating as well as cooling purpose and draw less amount of energy.
