Thermoelectric Multiutility Refrigerator Cum Heater

Abstract

In this paper, an thermoelectric multiutility refrigerator cum heater using peltier and pic controller is been focused. This proposed system consists of peltier crystal which is used to produce both refrigeration and heatness. Thereby providing simultaneous heating and cooling. The proposed system provides refrigeration as primary utility with bonus utility using TEC12706. This technique is primarily concentrated in medical arena. This setup concentrates on solar energy inorder to avert the environmental contamination.The minimum temperature of 25 degree for cooling and the maximum temperature of 60 degree for heating can be achieved. The overall setup is cost effective because solar always a onetime investment for long duration.
