分别采用大孔硅胶/氯化锂-甲醇和微孔硅胶-水复合吸附剂作为吸附制冷系统的工质对。对吸附性能进行了实验研究和比较。实验结果表明，回质过程能显著提高制冷量，而回热过程能更显著地提高性能系数。硅胶/氯化锂-甲醇冷却系统具有更高的吸附能力和工作压力。当热水入口温度、冷却水入口温度和冷冻水出口温度分别为85°C、31°C和15°C时，硅胶/氯化锂-甲醇冷却系统的比制冷功率（SCP）比硅胶-水冷却系统高59.5%。硅胶/LiCl-甲醇冷却系统也可用于冷藏。当热水入口温度、冷却水入口温度和冷冻水出口温度约为88°C、25°C和−4°C时，制冷量和COP分别为1.0kW和0.13。
Compound adsorbent of macro-porous silica gel/LiCl-methanol and micro-porous silica gel–water were used as working pairs in two adsorption cooling systems respectively. The adsorption performance was experimentally investigated and compared. The experiment results are that mass recovery process can improve cooling capacity significantly while heat recovery process can improve coefficient of performance (COP) more significantly. The silica gel/LiCl-methanol cooling system has higher adsorption capacity and working pressure. When the hot water inlet temperature, cooling water inlet temperature and chilled water outlet temperature are about 85°C, 31°C and 15°C, the specific cooling power (SCP) of silica gel/LiCl-methanol cooling system is higher by 59.5% than that of silica gel–water cooling system. The silica gel/LiCl-methanol cooling system can also work for cold storage. When the hot water inlet temperature, cooling water inlet temperature and chilled water outlet temperature are about 88°C, 25°C and −4°C, the cooling capacity and COP are 1.0kW and 0.13.
