In recent 20 years, the rapidly development of thermoelectric materials promotes thermoelectric s application in large scale cooling area, i.e.air-conditioner.

To provide quiet working environment for the driver of high-speed railway, a kilowatt scale air-conditioner was designed.Firstly, a novel thermoelectric cooler with maximum cooling capacity of 450 W was designed with 199 thermoelectric elements, and the cooling performance were investigated under milwaukee 2981-20 different cold and hot side heat exchange capacity.Second, the hot and cold side heat exchangers were optimized adopting genetic algorithm.

Finally, a high coefficient of performance (COP) thermoelectric air conditioning (TEAC) system was designed for high-speed railway locomotive.The TEAC system comprising 16 TECs achieved a cooling capacity of 2342 W with a COP of 0.5 in cooling mode, and meets one 1HP TEAC requirements.

The temperature field inside the locomotive was uniform and exhibited a wella peach blush mask linear correlation with the supplied air temperature.This research demonstrates the utility of high-power TEAC in high-speed railway carriages, providing valuable insights for the application of TEAC technology.
