Abstract

This thesis presents the description of the investigation about temperature reduction inside the car cabin using the solar car ventilator. The trapped hot air inside the car cabin can reach until 70°C if being parked in open condition for the several hours based on to the Malaysian climate temperature. This condition will cause a lot of problems as health disease and also to the car life expectancy. As the result from this condition, there were several products and researched have been made to overcome and reduce the effect of the trapped hot air. One of the product have been developed by the previous researcher is solar car ventilator. The purpose of this research is to compare and analyse the effectiveness of the temperature reduction using different number of solar car ventilator. The presentable in the market solar car ventilator have been upgrade by changing the size of solar panel and reposition it at the better condition to maximize the amount of the solar energy that can be absorb by the solar panel. The project was being held in an open space area in Ayer Keroh, Malacca by using a car model Proton Saga in the parking condition from 11.00 am to 4.00pm. The experiment being tested in 5 predefined condition where are by using an existing solar car ventilator without any modification, using a unit of the modified solar car ventilator, 2 unit of modified solar car ventilator, 3 unit of modified solar car ventilator and 4 unit of modified solar car ventilator. The result from the experiment shows that by using the existing solar ventilator, the car cabin temperature can be reduced until 49.8°c. Other than that, by using a unit of modified solar car ventilator, the car cabin temperature can be reach until 46.5°c. There is about 3.3°c of difference between both conditions. Anyhow, the car cabin temperature can be reduced until 41°c when 4 unit of modified solar car ventilator be used. All the data were being collected at the same car condition in the same range of time. The main objective of this research is to compare the effectiveness of the existing solar car ventilator with the modified solar car ventilator has been achieved.
