ADsorption process

Adsorption means the accretion of atoms or molecules on the surfaces of solid objects. In the evacuated reactor inside an InvenSor chiller, water molecules accumulate on adsorbent materials during the adsorption phase. These molecules come from an evaporator in which the refrigerant water evaporates at just a few degrees Celsius on account of the low-pressure and downstream adsorber.

The machine behaves like a cold water aggregate for the cooling application. The cold water temperatures are between 9°C and 20°C, depending on the specification. The thermally operated reactor provides the drive force instead of an electrically operated compressor.

The heat supplied, e.g. from a solar installation or CHP unit, is used to restore the reactor’s adsorption capability during the regeneration phase.

No actively moving components are required inside the reactor (vacuum area). It does not need to be opened for inspection or maintenance purposes and is therefore permanently welded shut. As only water is used, no corrosive or volatile refrigerants are required.
