Thermal flow formed by thermoelectric module type air-conditioner installed in the cabin of commercial trucks was investigated by using realizable k-ε turbulence model in the condition of incompressible, steady-state and three-dimensional numerical analysis. In consequence, the operating point of virtual fan comparatively shows high static pressure and low flowrate in each number of revolution. This means that the re-design of flow paths composing of air-conditioner is necessary for lower static pressure and larger flowrate. Anyway, the air cooling temperature difference in cabin obtained under the outdoor temperature of 40℃shows about 6∼9.7℃in the front of a driver"s seat and about 6∼9.2℃in a driver resting space at present circumstances, respectively.
