摘　　要：从提高吸附剂的太阳能吸收率及强化吸附发生器内传热的角度出发,设计了一种新型吸附发生器。该吸附发生器通过热管和平板集热元件可同时从内外表面加热或冷却吸附工质对。对该吸附发生器进行了热力分析和数值模拟。计算结果表明,在太阳辐射大于16M J/(m 2.d)的条件下,采用该吸附发生器的太阳能吸附式制冷系统即可有效地运行,系统制冷系数CO P可高于0.18。A novel absorber with heat pipe and flat plate dual collector is proposed for the purpose of enhancing solar energy flux in absorber and improving its heat transfer performance. A thermodynamic analysis and a numerical simulation have been performed on anadsorption cooling system with this kind of absorber. The results of calculation show that the adsorption cooling system has excellent performance. When the solar radiation is more than 16 MJ/m^2·day, solar adsorption cooling system can run effectively.
