Design and Fabrication of Thermoelectric Air-Cooling System

Abstract

A thermoelectric air-cooling system (TEACS) is an innovative technology based on the thermoelectric cooling phenomenon. The absence of heavy moving parts to obtain a cooling effect reduces intense vibrations than the traditional cooling system. Moreover, this system is eco-friendly as harmful coolants are not used or produce any harmful elements such as CFCs. The thermoelectric module works on direct current (DC), heating & cooling phenomena depending upon the direction of current flow. Peltier modules are made up of two unique semiconductor materials, such as Bismuth Telluride (Bi2Te3) in the form of pillars sandwiched between a pair of ceramic plates. This paper covers the design and fabrication of an automated thermoelectric air-cooling system. The Peltier module is sandwiched between two Aluminum heatsinks on each side of the Peltier module. Arduino microcontroller is used to provide automatic temperature control. Air is passed through the cold side, and water is used to reduce the heat on the hot side. This system reached 25°C within 300 seconds and 700 seconds to reach 15°C from 30°C ambient room temperature. The novelty of this TEACS has a COP of 1.13 achieved by careful adjustment of electrical parameters with a cooling capacity of 648 W, and the designs are fabricated by using eco-friendly materials.
