Users would adjust air conditioner knob position to regulate the cool air supply to the cabin. Essentially, adjusting the knob position would affect fuel consumption of the vehicle. Thus, this study is done to measure the fuel consumption of different thermostat level settings of an air conditioning system, in the case of stationary car, without passengers and driver in it. The data in this study were taken in four different modes and two levels of selected fan speed. At the same time, the cabin temperature was monitored by a specific device to record the temperature, relative humidity, and CO2 emission. Fuel consumption is monitored by filling 5 L of petrol into an external tank. After running for one hour, the total fuel consumption is calculated by measuring the remaining of the fuel amount. At the end of the experiment, the most practical and suitable thermostat level setting is proposed. Besides saving fuel, the outcome of this study showed that the most comfortable condition in the cabin is 25.83 °C, 51.72% relative humidity and CO2 is 553 ppm. The selected mode is actually at mode 4, low blower fan speed with the fuel consumption is amounted at 1220 mL. |
