Project Planning Team, Jeonbuk Institute of Automotive Technology, 1641-4, Soryong-dong,Gunsan-si, Jeollabuk-do 573-879, Korea(Received June 11, 2013 ; Revised August 20, 2013 ; Accepted August 25, 2013)Abstract − To reduce vehicle fuel consumption due to not only driving but also air conditioning, battery-operatednon-starting conditioning systems with thermoelectric modules and without mechanical elements like com-pressors are being manufactured for use by hybrid heavy trucks in the near future. In this study, the voltage andcurrent consumed by a thermoelectric module were measured to determine the required battery power, and theperformance of the conditioning system with air temperature, and humidity of the inlet/outlet modules and inside/outside the cabin for a truck, was evaluated using experimental apparatus under actual conditions. The resultsshowed that, the thermoelectric module can be continously operated for about 1.5 h using existing 24 V batteries.The coefficent of performance(COP) of the cooling and heating modes was calculated to be an average 0.8-1.32.As expected, the heating performance was 30% more efficient than the cooling performance, which is generalcharacteristic of thermoelectric modules.

Performance of Non-starting Conditioning System using Thermoelectric Modules for Hybrid Heavy Trucks

The improvement of cooling ability for the air conditioner is the most efficient method of application of its system. Therefore, this study has been investigated the improvement of cooling ability for the air conditioner using automotive by attached of a thermoelectric module. According to the result of test, capacity of the thermoelectric module make temperature range from _75℃ to + 300℃ possible to cooling and exothermic. In addtion to, the reduction effect of energy revealed and the effect of liquid hammer remained with safety by attached the thermoelectric module. It was found that the air conditioner system by attached thermoelectric module have better cooling ability than the air conditioner system of existing vehicle.
