Abstract

Car is commonly parked under exposure of sunlight directly. Increasing of air temperature in cabin vigorously due to heat trapped and transferred within the cabin causes thermal uncomfortable, heat stroke, and deformation of material within cabin. Therefore, a cooling device for car park under sunlight exposure is designed following engineering design process. Method of temperature reduction selected is the combination system of ventilation and thermoelectric Peltier cooling module. Prototype is fabricated to test the method selected and experiment is conducted from 11am to 3pm at same day and same venue by using three similar cars without tinted in three conditions: fully sealed cabin, cabin with prototype, cabin with single window gap of 4cm opened. Result showed that cabin with prototype has lowest average air temperature in cabin (41.25 ˚C), then cabin with single window gap opened (50.45 ˚C) and fully sealed cabin showed highest average air temperature in cabin (54.75 ˚C). The objective of this research is achieved with average air temperature reduction of fully sealed cabin that is 13.5 ˚C (24.66%) and cabin with window gap opened which is 9.2 ˚C (18.24%) when compared to the average temperature of cabin with prototype. Peltier module’s cooling efficiency is 25.21% and 21.74% when compared to fully sealed cabin and cabin with window gap opened respectively.
