| 摘 要： | 对额定制冷量为12.3 kW的风冷太阳能双级水喷射制冷空调系统进行了变工况性能分析。该系统的制冷量随室内温度升高而增大,随环境温度升高而减小,随太阳辐照度增强而增大;COP的变化与制冷量的变化类似,所不同的是COP随着太阳辐照度的增强先迅速增大,当太阳辐照度增大到一定程度后,COP基本保持稳定。在室内温度不低于27℃,室外温度不高于38℃,太阳辐照度不低于500 W/m2的条件下,系统的制冷量为7.7~32 kW,COP为0.082~0.107。

| Abstract: | The performance was analyzed for a solar-powered air-cooled two-staged water ejector cooling system that rated cooling capacity is 12.3 kW.The cooling capacity of the proposed system increases with the rising of indoor temperature and the enhancement of solar irradiance,while decreases with the rising of the ambient temperature.The COP has similar changing trend with that of the cooling capacity except that it increases rapidly with the enhancement of solar irradiance firstly and then become stable when the... |
