| Abstract: | The basic principle and operation of evaporative refrigeration with a porous window are described and a one-dimensional, steady-state mathematical model for the situation discussed is developed. By numerical calculation, the refrigerating and operating performance of the porous window is predicted and the influence of parameters of air and window construction on the performance are studied. Calculation results show that dry, hot and windy environment is favorable for porous window and a lower height of the porous layer with strengthened convection along the inner surface is helpful to the improvement of effective refrigerating capacity. By taking into consideration the regional distribution of environmental parameters in China, the prospects for application of porous window air-conditioning are discussed. |
