Summary The world is facing the ever‐worsening issues of global warming. The results show that the physical‐/chemical‐adsorbent water can improve the adsorption capacity of 1.22 kg/kg. If water is used as the adsorbate, the adsorbent has a serious issue of corrosion. So, methanol is utilized. However, methanol just can be heated by low‐temperature heat, because methanol will be broken down in above 140°C adsorption system. The multifunction adsorption system can produce one cold effect output and two power generation outputs. The results show that the silica gel/LiCl‐methanol multifunction adsorption system has a higher cooling exergy efficiency of 0.25 and a higher total system exergy efficiency of 0.87 compared with that of the silica gel‐water system.
