A Numerical Approach To Peltier - Based Cabinet Cooling System

Abstract

Nowadays, people use their car a lot which is proportional to the surge in HVAC systems in the vehicle, which is also an integral part of a car. Automobiles use refrigerant to cool the car cabinet, which causes a series of problems to the environment and contributes to the emission of CFCs, HCFCs, CO2, etc. The present HVAC system is very efficient and reliable, but it also has some demerits. According to the International Institute of Refrigeration, air conditioning and refrigeration consume around 15% of worldwide electricity. Usually, the Air conditioner in the car uses power (5-10% of engine power) from the engine, so this system consumes fuel indirectly. Automobiles cabinet heats up faster when it is stationary and under direct sunlight. During such a situation driver must turn on ac to maintain the temperature. To solve this problem, a product was designed with the help of CATIA software. The simulation is done using Ansys Fluent software, which divided the design into 2.1 million elements and solved with the help of triangular mesh. The simulation showed there is an almost 50% drop in temperature. This product uses a thermoelectric cooling technique that works on Peltier and Seebeck effect. Thermoelectric coolers (TEC) are an emerging technology used in the medical industry to cool medicine instantly. The cold side of Peltier with water was used to cool ambient air to a lower temperature that helps to cool the cabinet. This product helps to maintain car cabinet temperature at an optimum level, which is non – hazardous, low power consumption, retains moisture in the car and is finally Portable. The present model can cool ambient temperature from 55 to 26°C. Further, this investigation would lead to the determination of precise operating conditions for the experiment. © 2022 American Institute of Physics Inc.. All rights reserved.
