Abstract: Pentane is used as a refrigerant in the evaporative radiation air-conditioning system. With the constant opening of throttle valve，an experiment was conducted by changing the interior temperature. Measurements obtained include the cooling capacity of the evaporative capillary imbibitions conditioning system，the radiant panel face temperature，the temperature distribution in vertical direction of the simulated space under different cooling capacity. The results show that，under the research condition，heat transfer of the evaporative wick radiation plate increases from 44 W/m² to 91 W/m². Even under different cooling capacity，the temperature distribution of the board is uniform，the minimum temperature is above 24℃，which can guarantee the system running without condensation. The temperature in the simulated space values are in the range of 24.5—27.5 ℃，which can meet the temperature requirements of human comfort. Thus，compared with traditional radiation air-conditioning unit，the evaporative capillary imbibitions core radiant panel air-condition system possesses higher cooling capacity and lower risk of condensation. The work in this paper can provide a theoretical basis for its further application.
