When the desorptionprocess is finished, then the next folloes evaporation adsorption process text. Open the
adsorbent bed of cooling water circuit, then the pressure and temperature reduced quickly. This is the adsorption
refrigeration cycle in third phases namely, adsorption cooling stage.When the pressure in the adsorption bed reduces
to the set of the evaporation pressure, open the adsorption bed and the valve of the evaporator, and opening the
refrigerant water circuit, the liquid ammonia continuously evaporated in the evaporator and is adsorbed to the
activated carbon of the adsorbent bed. Then the temperature of the chilled water drops ceaselessly, the pressure of the
process is maintained in the evaporation pressure or so. When the average temperatures in the adsorbent bed drop to
the setted adsorption temperature, close cooling water circuit and the valve before the evaporator, then the whole loop
is ended.
