摘　　要：在夏季典型工况下,对一个小型太阳能吸收式空调系统进行了试验研究。试验系统主要包括:96m^2的真空管集热器、额定制冷量为8 kW的吸收式制冷机、容量为3 t的热水储水箱、500 L蓄冷水箱以及50m^2冷辐射吊顶。试验结果显示吸收式制冷机的制冷量平均为3.9 kW,每天达到的平均制冷时间为10 h。分析了室内的热舒适情况,得出了PMV值为-0.2%,PPD值为5%,室内热环境达到舒适水平。Experiments were carried out to study a minitype solar absorption air-conditioning system in the summer typical condition. The system consists of 96 m^2 vacuum tube collectors, one adsorption chiller with nominal refrigeration capacity of 8 kW, hot water storage capacity of 3m^3 , cooling water storage capacity of 500L and 50 m^2 cooling ceiling. The experimental results show that the adsorption chiller has an average cooling capacity of 3.9 kW, achieving a mean cooling period of 10 h of complete solar autonomy on a seasonal average day. The work shows results on system performance, matching characteristic about cooling load, refrigera- ting capacity , collected power and solar radiation power. It also reflects operation about cooling ceiling and thermal comfort in the air-condition room.
