Developmental and Experimental Study of Solar Powered Thermoelectric Refrigeration System

Design and developmental methodology of thermoelectric refrigeration has been explained in detail also the theoretical physical characteristics of thermoelectric cooling module used in this research work have been investigated. Authors have been designed and developed an experimental prototype of thermoelectric refrigeration system working on solar photo voltaic cells generated DC voltage. The developed experimental prototype having a refrigeration space of 1liter capacity is refrigerated by using four numbers of Peltier module (Supercool : PE063-10-13, Qmax=19W) and a heat sink fan assembly used (Model No: TDEX6015/TH/12/G, Rth=1.157 o C/W ) to increase heat dissipation rate from hot side of Peltier module. The experimental result shows a temperature reduction of 11 o C without any heat load and 9 o C with 100 ml water kept inside refrigeration space in 30 minute with respect to 23 o C ambient temperature. Also the COP of refrigeration cabinet has been calculated and it is 0.1. The developed thermoelectric refrigeration system is having potential application of storage and transportation of life saving drugs and biological materials at remote areas of our country where grid power is unavailable.
