Abstract

The climate in Malaysia is hot and humid for a prolonged period of time. Simply put, if parking a car in the scorching sun, the interior temperature would rise significantly, making the passengers irritated and uncomfortable. Nevertheless, the trapped heat is causing damage to the interiors and components inside the car cabin. For instance, excessive heat reduced functionality or even malfunction to the electronic devices inside the car cabin such as the touch screen display and the dashcam. The temperature inside a car may rise to as much as 36°C or even higher than 50°C, due to the accumulation and trapping of heat. Although there are various existing inventions and technologies designed to help reduce car cabin temperature, yet there are pros and cons associated with these inventions and their applications vary depend on different circumstances. The purpose of this research is to design and develop a solar mist system system to reduce the car cabin temperature. Experiments were conducted under two different types: one involving a car equipped with a solar mist system and the other without. All of the experiments were conducted on sunny days between February 2024 to April 2024. The car cabin temperature of the car equipped with the solar mist system system was found to be able to maintain between 37.75°C to 40.75°C while the car without equipping the solar mist system system kept on rising rapidly. Througout the entire experiments conducted with the current design of solar mist system system prototype, the protoype is able to reduce the car cabin temperature by 14.24% which is approximately 6.34°C or 43.41°F in average.
