How we use solar radiation, ground temperature to make cooling sustainable.
Where others rely solely on electricity, Zerocool draws energy from the environment.
Well aware that AI computers are not always 100% utilized and thus provide a constant energy flow, the Zerocool solution uses two sustainable energy sources that complement each other: solar thermal energy and ground-based cold. Both systems are used dynamically, with the configuration being adapted according to factors such as season, time of day and cooling demand.
The outcome is a dual utilisation of nature's capabilities, functioning in two distinct seasonal modes to ensure optimal utilisation of natural thermal energy.
Solar collectors capture renewable heat from sunlight to drive the adsorption chiller and to cool in winter nights.
Geothermal collectors tap into stable subsurface temperatures to buffer and deliver thermal energy year-round.
During the summer, the amount of heat energy from the CPU'S / GPU'S can be increased / supplemented by additional heat from a solar thermal system. A solar thermal system with approx. 1,300 m² generates approx. 1 MWh of thermal output of over 55°C from mid-March to the end of October. This thermal energy is also temporarily stored in the energy storage system and thus supplements the idle time of the processors. At the same time, surplus cooling energy can be temporarily stored in the cold local heating network.
In winter, solar thermal energy can be used to generate additional cold, especially at night when the solar system's tubes get very cold. At the same time, the cold local heating network can be used to store heat in the ground, which can be used again on transition days. The dual use of all the technologies employed underpins the effectiveness of the Zerocool solution.
Zerocool’s architecture is modular by design. Each component contributes to the overall thermal strategy—working together to adapt cooling performance to site conditions and seasonal shifts.
This is where heat becomes cold.
The adsorption chiller is the core engine of zerocool.
Our hybrid storage setup combines pcm and concrete to store and release thermal energy as needed
