Cooling Environments/Heat Reuse

Welcome

Welcome to the OCP Heat Reuse Sub-Project. Efficient energy usage of data centers is a key global concern and tenant of Open Compute Project (OCP).

ITE and data center design efficiency is just one factor in minimizing the carbon footprint associated with energy usage of a data center - use of renewable resources and reuse of its waste energy can have a positive impact as well.

Almost 100% of the energy used in a processor turns into heat.

Up until very recently this has been a liability and a challenge, immense quantity of heat needed to be removed employing even more energy for it. With the proper design, data center cooling systems can be converted into a heat source and a heat management opportunity that in turn converts the heat from a liability to an asset.

The OCP Heat Reuse subgroup explores these challenges and opportunities. Its goal is to suggest solutions to allow easier implementations of technologies aimed at harnessing the heat and turn it into profit instead of a cost.

This Project is open to the public and we welcome all those who would like to be involved.

Subproject structure

MAIN SUBPROJECT CALL: Heat Reuse

Every 4 weeks, Tuesday 8-9 AM PT // 11-12 AM ET // 5-6 PM CET (see Calendar)

Guest presentations

Discussion and presentation of the workstreams' results

WORKSTREAMS:

Reference Designs

Every 4 weeks, Thursdays 8-9 AM PT // 11-12 AM ET // 5-6 PM CET. First call the 22nd of June 2023 (see Calendar)

Work:

-How does a “heat recovery room” look like?

-Definition of spacing, elements, basic parameters;

-Influence of size;

-In a second stage, define different application scenarios (district heating, greenhouse, swimming pool…) as variables of the base design;

Deliverables:

-Reference tools (tools for equipment dimensioning);

-Tables with equipment to be employed; tables with parameters;

-Drawings;

Expertise: MEP knowledge, in particular hydraulic systems and controls, technical drawing, technical dimensioning

TCO Analysis

Every 4 weeks, Thursdays 8-9 AM PT // 11-12 AM ET // 5-6 PM CET. First call the 29th of June 2023 (see Calendar)

Work:

-Define how much does a baseline heat reuse project cost. Boundary: the data center exchange room.

-Define variables and parameters of influence,

-Influence of size,

-In a second stage, define different application scenarios (district heating, greenhouse, swimming pool…) as variables of the base design

Deliverables:

-model with the financials of heat reuse:

-base case(s) definition / example case /parameters to consider / boundaries

-Cost analysis of equipment

-White paper with an analysis of the results

-water usage, carbon emissions model: (separate workstream ? 🡪 that is not TCO )

Expertise: MEP knowledge, in particular hydraulic systems and controls, technical drawing, technical dimensioning

(Necessary consideration of the results from other workstreams: Policies around heat reuse / Reference designs)

Policies around Heat Reuse

Every 4 weeks, Tuesdays 8-9 AM PT // 11-12 AM ET // 5-6 PM CET. First call the 27th of June 2023 (see Calendar)

Work:

-identify barriers, needed actions and highlight sample policies around the globe for heat reuse in data centers

Deliverables

Whitepaper:

-an introduction/summary which makes the case for reusing data center waste heat;

-a section which identifies key hurdles or barriers, general actions which governments can take, and 1-2 examples of good policies where they exist; and

-a final section on potential people or organizations to engage who are outside of the OCP with whom we might engage.

Expertise: Understanding of regulation bodies and how they are structured; the timelines; the language; the hierarchical levels
