Operating Cycle:

During the initial start-up of the machine, the entire pressure vessel is evacuated with the help of a small evacuation-pump, that is permanently installed for this purpose.
The machine operates fully automatically with an operation cycle of about 5 to 7 minutes, that consists of mainly four steps:
Step 1
Water is brought into the evaporator and evaporates. Through this, the cooling circuit cooles down.
 
Step 2
The water evaporated in step one is adsorbed on the receiver.
Step 3
The adsorbed water is de-adsorbed with the supply of thermal energy. The receiver turns into the generator.
 
Step 4
The de-adsorbed water is condensed in the condenser (cooling cycle).
The cycle is completed with the re-turn of the in step 4 condensed water into the evaporator (step one).
 

Receiver and Generator are alternately heated and cooled.
During the heating of the one side, the receiver is partially cooled by the cold water flow of the condenser, to draw off the heat created through the adsorption. After the cycle-time expiration the machine switches over by means of pneumatically actuated valves.
The different chambers are connected with automated brackets. the operating method of the brackets is determined by the pressure differences in the chambers during the operationcycle. The machine does not contain any costly or maintenance requiring parts inside the evacuated chamber!
The refrigerant reaches the upper part of the evaporation chamber either through weightlessness or with the help of a small pump. During the evaporation process there, it wanders down through cascades.
