Abstract

A car parked under direct sunlight for several hours can causes the temperature inside the car cabin increase and heat soak. This due to the closed design of the car cabin and the component made by heat conductor will rapid increasing the temperature. The hot temperature inside the car cabin makes the driver and passenger feel uncomfortable and affecting the degradation interior component besides the heat harmful to human and animals. This project is done to find suitable method to overcome these problem. All car parked under direct sunlight. The conditions are choose for this study; first experiment without use any additional material (Case 1), second experiment using sun shade and close all the windows (Case 2), third experiment using sun shade and open all windows approximately 2 cm (Case 3) and fourth experiment using sun shade, open front window approximately 2 cm and use fan powered by solar (Case4). The main idea of this study is to find suitable method to reduce the heat in shorter time. Temperature different data for each method collected using thermocouples and data logger, then the effective method chosen based on the time to reduce the temperature in car cabin. . For analysis by point, results shows that Case 4 have highest average temperature difference for all point with value of 8.99 °C followed by Case3 and Case 2. For analysis by time, results shows Case 4 can achieve the lowest percentage temperature difference with outside temperature during the experiment carried out for 180 minutes with value of -2.77% followed by Case3 and Case 2.
