(2) The regeneration conditions, temperature, gas pressure, PH value and so on, will influence on the activated performance of the adsorbent. Therefore, after the adsorption capacity of the adsorbent in cooling machines deteriorates, the surface activity of the adsorbent would be restored through these measures of pressurizing adsorption pressure, depressurizing desorption pressure, regulating the PH value of vapor, infilling some solution with right PH value, washing and controlling the regeneration temperature.
