Re: Heat Reuse designs, metrics, market - Creation of workstream [EXT]

Archibald, Matthew
On the back of what Francois stated, the CDU should be regulating the fluid flow and temperature on both the primary (FWS) and secondary (TCS) loops.
On the primary side, the flow can be controlled to get a more consistent primary return temperature while still maintaining tight operating conditions for the secondary loop. One of the easiest ways to accomplish this is with dynamic flow on the primary, and CDUs with lower and constant approach temperature support across the operating range.

Hi all,
I am very interested in that topic.
The heat pump will have a COP of 6 to 8 and will act as a regulator of the facility water temp. Anytime I saw colleagues advocating for direct heat reuse, we saw pushback from facility management.
Also, we should not advocate on “running dummy code” to heat the system (I really saw people using that…) as the COP of a CPU is 1… regulation by the CPU load is not a sustainable strategy.
Last but not least, the facility management investment is a 10 to 25y CAPEX, while IT is a 3 to 7y. the heat pump will ensure the hot water loop and the DC loop will remain compatible.
François.

Heat reuse success in Singapore is impressive! Expect that metrics and incentives would help spur advancement of practicality

Here in hot & humid Singapore/Tropics, we are working to use low grade waste heat (~40°C) from DC for regeneration of desiccant dehumidification which can be coupled with IEC for DC cooling. Will be most glad to be part of this work stream.

Heat reuse is gaining momentum in regions that are cool, have district heating infrastructure, motivated by sustainability Northern EMEA has all three. China is also advancing in these areas,
USA generally is warmer or does not have district heating type applications near data centers Agricultural applications are also common, but rather superficial in many ways (growing bananas in Norway is not really a promotion of sustainability).
Increasing the quality of heat (higher temperature liquid) broadens application options beyond cold climate agriculture and district heating 30 C waste heat is almost useless outside of cold climates, but 60C waste heat liquid has many applications Input from Intel is needed to validate whether 60C waste heat makes sense
Cloud&Heat is an example of edge data centers providing utility that can be applied almost anywhere https://www.cloudandheat.com Key goal is promotion of vision to drive development of solutions that are cost effective and efficient.
Open to correction and insights

What is the driving force behind EMEA and APAC early adoption of heat reuse? Or do barriers exist to adoption in North America?
