7 terms

direct-to-chip liquid cooling technical

"additional guides covering absorption chillers and direct‑to‑chip liquid cooling to follow."

A cooling method that pumps liquid directly over the surface of a computer chip (processor or graphics unit) using a fitted plate, removing heat more efficiently than air or indirect systems. Think of it like a water jacket on an engine: keeping the hottest part cooler lets the equipment run faster, longer, and in a smaller space, which can lower energy and space costs and enable higher-performance products—factors that affect operating margins, capital needs, and adoption potential for companies and data centers.

fan coil walls technical

"integrates high‑efficiency air-cooled YORK centrifugal chillers ... fan coil walls (FCWs) and coolant distribution units"

Fan coil walls are sections of a building’s interior wall that contain a fan coil unit — a compact heating and cooling device that blows conditioned air through a space. For investors, they matter because these built-in HVAC components affect a property’s energy use, tenant comfort, maintenance needs and retrofit costs, much like knowing whether a car has an easy-to-service engine under the hood or one welded into the chassis.

coolant distribution units technical

"chillers ... fan coil walls (FCWs) and coolant distribution units (CDUs) to manage both air‑ and liquid‑cooled IT loads."

Coolant distribution units are pieces of equipment that circulate and regulate liquid or gas used to remove heat from machinery, electronics, or industrial processes — think of them as a building’s heating/cooling plumbing or a car radiator for factory equipment. For investors, they matter because they influence a facility’s reliability, energy use, maintenance needs and regulatory compliance; costs or upgrades tied to these units can affect operating expenses, capital spending and the competitiveness of companies that rely on precise temperature control.

coefficient of performance (cop) technical

"30% Coefficient of Performance (COP) improvement and 27% fewer chillers from raising the chilled water"

Coefficient of performance (COP) is a measure of how efficiently a heating or cooling system turns electrical or fuel energy into useful heat or cold: it’s the amount of heat moved per unit of energy consumed. For investors, a higher COP means lower operating costs, stronger product competitiveness, and better alignment with energy-efficiency regulations and incentives—think of it like miles per gallon for climate-control equipment.

technology cooling system (tcs) technical

"27% fewer chillers from raising the chilled water temperature to support warm-water Technology Cooling System (TCS) loops."

A technology cooling system (TCS) is the set of equipment and processes that remove heat from electronic hardware such as servers, data centers, telecom gear, and other high-power devices to keep them within safe operating temperatures. Like a car radiator or home air conditioner for machines, it matters to investors because cooling affects reliability, energy costs, capacity limits and lifespan of assets—impacting operating expenses, uptime and the need for future capital spending.

ai factory technical

"Johnson Controls ... is expanding its AI Factory Reference Design Guides with the launch of its second guide"

An "AI factory" is an organizational setup that combines data, software, computing power and repeatable processes to build, train, deploy and monitor artificial intelligence systems at scale — like an assembly line for AI models. Investors care because a well‑run AI factory can lower costs, speed product delivery and create predictable revenue streams from many AI-powered products, making a business more competitive and scalable in a measurable way.

gigawatt‑scale ai factories technical

"A globally repeatable blueprint for cooling gigawatt‑scale AI factories efficiently and sustainably"

Gigawatt‑scale AI factories are very large facilities or networks of data centers that house the powerful computers and cooling systems needed to train and run advanced artificial intelligence models, consuming electricity on the order of gigawatts (comparable to a small city). For investors, they matter because they require huge upfront capital, ongoing energy and real‑estate costs, and can drive substantial revenue if filled with paying customers or proprietary models, but also bring regulatory, supply‑chain and sustainability risks.

• A globally repeatable blueprint for cooling gigawatt‑scale AI factories efficiently and sustainably
• Supports zero‑water cooling, eliminating cooling towers and saving 12+ million gallons of water per day.
• Enables high-efficiency air-cooled designs that can return up to 50 MW to the AI factory and improve annual energy consumption by 32%

MILWAUKEE, May 5, 2026 /PRNewswire/ -- Johnson Controls (NYSE: JCI), a global leader in thermal management, mission-critical building systems, energy efficiency, and decarbonization, is expanding its AI Factory Reference Design Guides with the launch of its second guide, focused on air-cooled chillers. Building on the company's water‑cooled chiller guide released in February, this latest blueprint marks the next step in what will be the industry's most comprehensive set of global design guides mapping the full data center thermal chain — with additional guides covering absorption chillers and direct‑to‑chip liquid cooling to follow.

As AI brings new scale and complexity to data center design, operators are facing mounting challenges including the power needed for cooling systems, rising cooling‑loop temperatures, efficiency losses from heat islands and limited water availability. Johnson Controls' AI Factory Reference Design Guide Series addresses this challenge by outlining how designers and operators can achieve industry‑leading energy and water efficiency and minimize noise impact on surrounding communities while remaining adaptable to different climates, workloads and growth paths.

The new guide supports the scalable design of data centers of all sizes, up to a 1-GW AI factory, utilizing air-cooled chillers. It outlines a comprehensive thermal cooling architecture that integrates high‑efficiency air-cooled YORK centrifugal chillers (including its YDAM and YVAM chillers), fan coil walls (FCWs) and coolant distribution units (CDUs) to manage both air‑ and liquid‑cooled IT loads. The guide provides sizing references for 220MW compute clusters, including recommended design temperatures and operating conditions across each stage of the thermal chain.

Key outcomes enabled by the design guide include:

• 50MW returned to the AI factory through the implementation of bifurcated loops for air- and liquid- cooling systems.
• 32% improvement in annual energy consumption through the intelligent utilization of redundant chillers.
• 20MW peak power savings by quantifying and mitigating heat island effects of air-cooled chiller plants.
• Zero water usage saves over 12 million gallons daily by eliminating the need for cooling towers to produce facility water.
• 30% Coefficient of Performance (COP) improvement and 27% fewer chillers from raising the chilled water temperature to support warm-water Technology Cooling System (TCS) loops.

"At gigawatt scale, AI factories require a fundamentally different way of thinking about infrastructure," said Austin Domenici, president, Johnson Controls Global Data Center Solutions. "The future requires designing integrated systems that can scale predictably, perform efficiently and adapt as technology evolves. This guide reflects how Johnson Controls helps customers plan holistically for AI growth, from design to operations, anywhere in the world."
