Air-cooled garments are designed and the cooling capacity

state parameters

and flow rates of the air inlet and outlet are determined. The refrigeration capacity required by the cooling device matching that of the garment is calculated. Experimental and numerical simulations of a thermoelectric refrigeration device are conducted. The accuracy of the simulation results is verified by comparing the experimental data with the simulation results. An optimization scheme for refrigeration devices is proposed. The thermoelectric refrigeration device is optimized by validated numerical simulation calculation models

which can provide 6.283×10-3 m3/s of cold air at 29 ℃ for a garment under the dry bulb temperature of 34.4 ℃ and wet bulb temperature of 27.9 ℃

and the device can meet the design requirements of the air-cooled garment.
