摘要： 由太阳能热驱动的吸附式冷热联供系统可以输出温度适宜的冷风和生活用水，且无需冷水回路和冷水驱动水泵，可满足小型化应用的需求.为了探究该系统的运行性能及其影响因素，对1种由2个吸附床、1个冷凝器和1个重力热管型蒸发器组成的硅胶-水吸附式冷风机进行了实验研究，确定了机组的动态运行特性.结果表明，机组能够有效利用62～85℃范围内的太阳能热水，系统的冷量为0.95～2.76kW，制冷性能系数为0.24～0.46，综合性能系数为 1.48～2.40，机组单个循环最佳制冷时间为750s.当驱动热水、冷却水和冷风的进口平均温度分别为85.1℃、29.9℃和29.5℃时，冷风和冷却水的出口平均温度分别为22.4℃和40.1℃.实验结果为高效利用太阳能实现冷热联供提供参考依据.

Abstract: The adsorption cooling and heating cogeneration system driven by solar thermal energy can produce cold air and domestic water with a suitable temperature. It does not require a cooling water circuit and a cooling water pump but can meet the needs of miniaturized applications. In order to explore the operation performance and influencing factors of the system, an experimental study was conducted on a silica gel-water adsorption air cooler with two adsorption beds, a condenser and a gravity heat pipe evaporator. The dynamic operating characteristics of the cooler were obtained. The results show that the cooler can effectively utilize the solar hot water in the range of 62℃ to 85℃; the cooling capacity ranges from 0.95kW to 2.76kW; the system refrigeration coefficient of performance ranges from 0.24 to 0.46, and comprehensive coefficient of performance ranges from 1.48 to 2.40; and the optimal cycle time for a single cycle of the cooler is 750s. When the average inlet temperatures of hot water, cooling water, and cold air are respectively 85.1℃, 29.9℃, and 29.5℃, the average outlet temperatures of cold air and cooling water are respectively 22.4℃ and 40.1℃. The experimental results provide reliable information for the efficient use of solar energy to achieve cooling and heating cogeneration.
