Cooling System Utilizing CO2 Heat Pump Water Heaters and Absorption Chillers for Waste Heat Recovery in Data Center Cooling Systems

An energy-efficient cooling system for data centers designed to capture discarded waste heat and recycle it as a reusable energy resource, drastically lowering operational costs and carbon footprints.

The Invention

Data centers require extensive cooling to handle massive device heat, but traditional chiller systems simply discard the resulting waste thermal energy. This invention introduces an efficient cooling system that captures and recovers this wasted heat. The technology introduces an advanced cooling system designed to capture the waste heat generated within data center cooling infrastructures. By reclaiming this energy, the system improves overall energy efficiency and reduces thermal energy loss.

 

Market Opportunity

The exponential growth of cloud computing, AI processing, and big data infrastructure has led to a massive surge in data center power consumption and heat generation worldwide. Cooling typically accounts for up to 40% of a data center’s total energy utilization. As regulatory bodies enforce stricter carbon emissions targets and Power Usage Effectiveness (PUE) metrics, data center operators are actively seeking sustainable infrastructure upgrades. This technology directly targets the multi-billion-dollar data center cooling market, offering a high-ROI solution for colocation facilities, enterprise data hubs, and hyperscale cloud providers.

 

Applications

Integration into massive infrastructure setups to lower large-scale thermal footprints.
Exporting recovered high-grade data center waste heat to local municipal grids or nearby commercial buildings.
Providing sustainable, energy-efficient infrastructure as a premium feature for multi-tenant data clients.

 

Key Benefits

Recovers and repurposes high volumes of waste heat that are traditionally lost to the environment.
Drastically reduces electricity bills by decreasing the net power required to run primary chilling and facility heating systems.
Lowers Power Usage Effectiveness (PUE) scores, helping facilities comply with modern green building standards and environmental regulations.
