REFRIGERANTS
data centre grows and technology advances. This means that the cooling solution can meet the growing demand for the data centre.
Redundancy is often built into a data centre cooling systems’
infrastructure to accommodate for downtime and allow uninterrupted operation. A redundant data centre architecture can replicate important components such as chillers, pumps, and fans, meaning that operations continue in the instance of a component failure or switch between diff erent cooling technologies so if one system fails, the other can be used. Many companies also actively balance load across diff erent data centres and therefore have the capability to provide backup in case of a complete failure. Honeywell continues to work closely with the industry to enable the transition to more sustainable refrigerant-based systems that drive down water consumption and, using ultralow and low GWP refrigerants, achieve carbon reduction goals. As the climate crisis continues, new legislation and
government action is expected. Local utilities may also take matters into their own hands. For instance, utility company Thames Water is considering restricting the water use of data centres in London. The UK’s largest water utility might add fl ow restrictors to pipes and charge more for water at times of peak demand.

The industry itself also self-regulates to meet climate goals. Last year, the Climate Neutral Data Centre Pact (CNDCP), an
initiative signed by 74 data centre operators and 23 associations, presented its proposed metrics for water conservation to the European Commission. The CNDCP has proposed a goal to the European Commission to cut water usage to a maximum of 400ml per kWh (400 litres per MWh) of computer power by 2040, down from 3000ml today. This voluntary target is highly ambitious and demonstrates the commitment of the European data centre industry to reducing its impact on the environment.
