摘　　要：对基于辐射供冷的太阳能吸收式空调系统进行了试验。该系统采用96m2的U型管式真空管太阳能集热器驱动额定制冷量为8kW的吸收式制冷机组，吸收式制冷机产生的冷冻水被输送到辐射吊顶中，为50m2的实验室提供夏季空调。吸收式制冷机运行在夏季晴朗天气时，平均制冷量为4．5kW。辅助独立除湿机组与辐射吊顶联合运行。试验房间的热舒适指标PMV为-0．29～0．32，可满足热舒适要求。Experiments were carried out to study a solar powered absorption cooling system based on cooling ceiling. The 96 m2 U-type vacuum tube collectors were employed to drive the absorption chiller with nominal refrigeration capacity Of 8 kW. The chilled water from the absorption chiller was delivered to cooling ceiling, providing cooling capacity to the 50 m2 test room. Under sunshiny weather conditions, the average cooling output was 4.5 kW. An independent dehumidification unit was installed to work together with cooling ceiling. The PMV inside the test room ranged from -0.29 to 0.32, which met the indoor thermal comfort.
