Powered by solar thermal energy it operates independent from electricity.
Long-lasting & Robust
System requires no short-lived batteries and contains no easy to break electronics or rotating parts.
No running costs as it is powered by hot water from abundant solar heat.
CO2 emissions are 10 x lower compared to conventional fridges.
Uses no hazardous materials, which makes it unproblematic upon disposal.
Enables reliable cooling for people without access to stable electricity.
HOW IT WORKS
The Adsorption Cooling Cycle
Part of the water evaporates in the evaporator due to low pressure in the system. The resulting evaporation cooling effect cools the storage compartment.
The adsorbent attracts vapour, binds it on its surface and frees up space in the evaporator. In that space more water evaporates, so multiplying the cooling effect.
Once the adsorbent’s surface is full of vapour, cooling temporarily pauses. In order for the process to be repeated, the adsorbent has to be dried.
By heating the adsorbent is dried and all vapour is released from its surface. The vapour condenses and flows back into the evaporator, which completes the cycle.
