Abstract

In the present scenario, Heating, Ventilation and Air Conditioning (HVAC) system commonly uses the efficient air conditioners but it has some demerits. The application of conventional system however, emits harmful gases such as freon, ammonia or carbon dioxide. The purpose of this study was to analyse the use of thermoelectric air conditioning system in cars to improve the Coefficient of Performance (COP) value. The simulation method was used to analyse the air flow through a chamber. The results showed with the current design, the COP value is able to achieve more than 2, which is significantly higher than previous studies. The temperature analyses at the outlet of the cooling chamber was done in order to calculate the COP value with varying the velocity of air flow. The outcome with higher base dimension of heat sink and higher number of fins resulted in better efficiency. This is because the heat sink strongly influences the COP value
