Adsorption isotherms of DH 5, DH 7, silica gel and 13 × were studied experimentally.The adsorption isotherms of DH 5 and DH 7 adsorbents were determined, The effects of adsorption capacity, air humidity, regeneration temperature and unit quantity of adsorbent on the dehumidification process were discussed.The results show that the dehumidifying performance of DH 5 and DH 7 is superior In the conventional adsorbents (silica gel and 13x), the maximum equilibrium adsorption capacities of DH 5 and DH 7 adsorbents were 0.72 kg / kg and 0.73 kg / kg, respectively. Regeneration at 100 ℃, dehumidification of DH 7 adsorbent The cooling capacity is 2.2 times that of silica gel, and the cooling capacity per unit mass of adsorbent is 1.9 times as that of silica gel. The dehumidifying cooling capacity of DH 5 adsorbent is 13x at the higher regeneration temperature (2000 ~ 250 ℃) 1.3 times the unit mass DH 7 adsorbent cooling power is 2.3 times the 13x.
