This phenomenon is photoreactivation[1].
Then 1 mL of diluted water sample was mixed with agar medium(less than 40℃).
(1) UV inactivation efficiency= lg(N0/N)
The UV irradiation dose was 0.6mJ/cm2, the disinfection efficiency reached 96.60%.The irradiation dose was 1.8mJ/cm2,the disinfection efficiency reached 99.20%.

Adsorption refrigeration machine is mainly composed of the adsorbent bed, condenser, evaporator and control valve, as shown in figure 1.
Open the valve 3, the steam in the evaporation chamber 1 through a valve 3 into the adsorption bed 2 is activated carbon adsorption and heat release; as the steam is continuously adsorption, evaporation chamber 1 refrigerant steam pressure decreases resulting in continuous evaporation from methanol and take away the heat so that the temperature drop around.
Figure 1B is on the desorption process description: open the valve 3 and the saturated adsorption bed 2 heating, adsorption bed 2 activated carbon after absorbing the heat temperature began to release the adsorption desorption of methanol, methanol steam through the valve 3 into the evaporating chamber 1 exothermic and condenses into liquid stored in the evaporation chamber 1.
