簡介目錄

2026年人工智慧資料中心廢熱回收系統市場規模估計為8.2億美元，預計2032年將達31.7億美元。這意味著在預測期內，複合年成長率將達到25.3%。

資料中心是持續產生熱能的來源。伺服器處理器、記憶體、電力電子設備和網路設備會將大部分輸入的電能轉換為熱能，而這些熱量必須被排出才能保證可靠運作。傳統的冷卻設計將這些熱量簡單地視為需要消除的負載。廢熱回收透過維持可用溫度、將熱量傳遞到清潔水循環迴路並將其連接到附近的熱需求源，從而改變了能源平衡。在人工智慧設施中，由於機架功率密度不斷提高，以及直接液冷系統能夠以比許多傳統風冷系統更高、更穩定的溫度將熱量傳遞給水，因此廢熱回收的應用前景更加廣闊。商業系統通常從資料中心的冷卻迴路開始。熱交換器將IT冷卻迴路與熱回收網路隔離。幫浦、閥門和控制設備確保了安全的液壓分離。如果回收水的溫度低於接收網路所需的溫度，工業熱泵會將溫度提升到可用水準。蓄熱系統可以緩解伺服器恆定的熱量輸出與波動的加熱需求之間的差異。最終連接目的地可以是區域供熱供應商、附近園區、工業流程、溫室或其他區域熱負荷設施。因此，經濟效益不僅取決於資料中心本身，還取決於熱接收方的溫度、距離和利用。在歐洲，由於相關法規的限制，這項功能的重要性日益凸顯。歐盟指令 (EU) 2023/1791 要求成員國對總額定能量輸入超過 1 兆瓦的資料中心利用廢熱或其他廢熱回收方式，除非能夠證明在技術上或經濟上不可行。歐盟委員會也要求對適用的新建或重大維修設施進行設備層面的成本效益評估。這使得即使在建造時無法直接連接區域供熱系統，對包含熱回收功能的冷卻設計也產生了結構性需求。

市場促進因素

人工智慧液冷技術能夠提升可回收熱量的品質。風冷資料中心通常產生的熱量品質較低，需要大幅提高溫度才能連接到傳統的區域供熱網路。晶片級直接冷卻 (DTC) 和熱水液冷技術能夠以更高的溫度將熱量輸送到水循環迴路，從而降低下游熱泵壓縮機的負荷。最佳化的高溫系統能夠實現直接或近乎直接的熱交換。隨著人工智慧機架密度的增加，熱回收也將受益於與冷卻劑分配單元、冷板和設施水系統相同的架構變革。
歐洲法規正將熱回收作為設計要求。歐盟的《能源效率指令》明確規定，對於超過1兆瓦的資料中心，必須利用廢熱，除非能證明不可行，這為熱回收提供了明確的監管動力。這意味著在設計過程中，熱回收將被更早納入考慮範圍。新建設施越來越需要維持適當的回水溫度，為熱交換器和熱泵預留空間，評估當地的熱需求，並在最終確定冷卻架構之前與供熱方進行協調。這項要求並不意味著所有項目都必須從外部供熱；相反，它擴大了熱回收設備和工程服務的市場。
區域供熱領域的夥伴關係正逐步走向商業化規模，已公佈項目的規模也不斷擴大。 Equinix 和 A2A 在米蘭的合作項目，圍繞著一台 72 兆瓦的熱泵、6000 立方米的蓄熱裝置以及每年高達 225 吉瓦時的餘熱回收量而設計。微軟和 Fortum 在芬蘭的一個開發項目旨在回收大規模資料中心園區產生的大量廢熱，最終滿足相當一部分區域供熱需求。這些項目表明，資料中心餘熱可以成為一種商業規模的熱源，而不僅僅是小規模的建築節能措施。這將有助於大規模的設備包和多年期綜合合約的簽訂。

市場限制因素

最大的限制因素是資料中心持續產生的熱量與經濟可行的供熱需求不符。大規模供熱網路集中在歐洲和亞洲部分地區的城市。許多北美資料中心遠離區域供熱基礎設施。此外，如果回收溫度較低，熱泵運作將需要大量電力，如果電價高昂，淨經濟效益可能會降低。季節性供熱需求、客戶合約、網路連接成本以及熱回收設備的所有權等因素都會使專案資金籌措變得複雜。運營商還必須確保冷卻系統的可靠性。外部供熱不得產生背壓、污染或控制依賴性，以免威脅IT系統的運作。有鑑於這些因素，採用水力隔離的模組化系統或由吸熱方直接參與設計和投資的專案更為合適。

Data centers are continuous thermal-energy sources. Server processors, memory, power electronics and networking equipment convert most incoming electrical energy into heat that must be removed to maintain reliable operation. Historically, cooling design treated this heat only as a load to be rejected. Waste heat recovery changes the energy balance by preserving usable temperature, transferring the heat into a clean hydronic loop and matching it with a nearby consumer. For AI facilities, the opportunity increases because rack power densities are rising and direct liquid cooling places the heat into water at higher and more stable temperatures than many traditional air-cooled systems. The commercial system normally begins at the data-center cooling loop. Heat exchangers isolate the information-technology cooling circuit from the recovery network. Pumps, valves and controls maintain safe hydraulic separation. Where recovered water is below the temperature required by the receiving network, industrial heat pumps raise it to a useful level. Thermal storage can buffer differences between constant server heat output and variable heating demand. The final connection may serve a district-heating utility, nearby campus, industrial process, greenhouse or another local thermal load. The economics therefore depend not only on the data center but also on the temperature, distance and utilization profile of the heat sink. Regulation is making the capability more important in Europe. Directive (EU) 2023/1791 requires Member States to ensure that data centers with more than 1 MW of total rated energy input use waste heat or another waste-heat recovery application unless technical or economic infeasibility can be demonstrated. The European Commission also requires installation-level cost-benefit assessments for relevant new or substantially refurbished facilities. This creates a structural demand driver for heat-recovery-ready cooling design, even when an immediate district-heating connection is not available at the time of construction.

Market Drivers

AI liquid cooling increases the quality of recoverable heat. Air-cooled data centers often produce relatively low-grade heat, which requires a large temperature lift before it can enter conventional district-heating networks. Direct-to-chip and warm-water liquid cooling can move heat into a hydronic loop at materially higher temperatures. This reduces compressor work in downstream heat pumps. In optimized high-temperature systems, it can allow direct or near-direct heat exchange. As AI rack densities increase, heat recovery therefore benefits from the same architectural shift that is already driving coolant distribution units, cold plates and facility water systems.
European regulation is converting heat reuse into a design requirement. The European Union's Energy Efficiency Directive creates a clear regulatory catalyst by requiring waste-heat utilization for data centers above the 1 MW threshold unless the project can demonstrate infeasibility. This moves heat recovery earlier in the engineering process. New facilities increasingly need to preserve useful return-water temperatures, reserve space for heat-exchange and heat-pump equipment, evaluate local heat demand and coordinate with utilities before finalizing cooling architecture. The requirement does not guarantee that every project will export heat. It expands the addressable market for recovery-ready equipment and engineering services.
District heating partnerships are reaching utility scale. The scale of announced projects is increasing. Equinix and A2A's Milan collaboration is designed around 72 MW of heat pumps, 6,000 cubic metres of thermal storage and up to 225 GWh of recovered heat per year. Microsoft and Fortum's Finnish development is intended to recover most of the waste heat from large data-center campuses and eventually supply a substantial share of local district-heating demand. These projects demonstrate that data-center heat can become a utility-scale heat source rather than a small building-efficiency measure. This supports larger equipment packages and multi-year integration contracts.

Market Restraints

The strongest constraint is the mismatch between continuous data-center heat production and economically accessible heat demand. Large heat networks are concentrated in Europe and selected Asian cities. Many North American data centers are located far from district-heating infrastructure. Low recovery temperatures can also require significant heat-pump electricity, reducing the net economic benefit when power prices are high. Seasonal heat demand, customer contracts, network connection costs and ownership of the heat-recovery equipment can complicate project financing. Operators must also protect cooling-system reliability. Heat export cannot create backpressure, contamination or control dependencies that threaten information-technology uptime. These factors favor modular systems with hydraulic separation and projects where the heat offtaker participates directly in design and investment.

Technology and Segment Insights

Industrial and high-temperature heat pumps represent the largest value pool because most data-center heat must be upgraded before it can enter existing district-heating networks. Their share is especially high in projects using conventional chilled-water or lower-temperature liquid-cooling loops. Heat exchangers form the second critical layer because they isolate the data-center cooling circuit from the external heat network and preserve equipment reliability. Recovery modules, hydraulic skids, thermal storage and controls form a growing packaged-systems segment as vendors standardize what previously required bespoke engineering.
District heating is the leading commercial reuse pathway because a single network can absorb large, continuous heat volumes and monetize them across many buildings. Campus and adjacent-building heating is attractive where the end user is under common ownership and connection distances are short. Industrial applications, greenhouses and aquaculture can absorb lower-temperature heat where local demand exists. On-site reuse is smaller in revenue terms but can support domestic hot water, process heat or thermally driven cooling depending on the facility design. The common requirement is a stable off-taker capable of using heat at the temperatures and hours available from the data center.
Air and chilled-water cooling produces low-grade heat, typically around 25-35 degrees Celsius. The primary recovery equipment includes a heat exchanger, large temperature-lift heat pump and controls. Commercial reuse includes campus heating, low-temperature networks and district heating with a heat pump. Rear-door and moderate-temperature liquid cooling produces moderate-grade heat, often around 35-50 degrees Celsius. The primary recovery equipment includes a heat exchanger, heat pump and hydraulic skid. Commercial reuse includes district heating, campus heating and industrial low-temperature loads. Direct-to-chip warm-water cooling produces higher-grade hydronic heat, often 45-65 degrees Celsius or above. The primary recovery equipment includes a heat exchanger, lower-lift heat pump and controls. Commercial reuse includes district heating, commercial heating and selected industrial uses. High-temperature liquid-cooled AI and HPC produces high-grade recovery loops approaching district-heat temperatures. The primary recovery equipment includes a high-efficiency heat exchanger and limited temperature lift or direct transfer. Commercial reuse includes district heating and high-value local heat applications.
The market is segmented by system component, heat source architecture, heat reuse pathway, data center type, deployment and geography. System components include industrial and high-temperature heat pumps, heat exchangers, heat recovery modules and substations, thermal storage, pumps, valves and hydronic equipment, and controls, metering and integration services. Heat source architectures include air and chilled-water cooling, rear-door heat exchangers, direct-to-chip liquid cooling, and high-temperature liquid-cooled AI and HPC. Heat reuse pathways include district heating networks, campus and adjacent-building heating, industrial and process heat, agriculture, greenhouses and aquaculture, and on-site thermal reuse and cooling. Data center types include hyperscale and AI factories, colocation data centers, enterprise and HPC facilities, and modular and distributed data centers. Deployments include new build and retrofit and expansion.
Europe is the largest early market because regulation, district-heating density and data-center growth are converging. European Union rules require waste-heat utilization for data centers above 1 MW unless technically or economically infeasible. Liquid cooling raises the temperature and recoverability of server heat compared with conventional room-air cooling architectures. Large industrial heat pumps remain the main enabling technology where district-heating supply temperatures exceed data-center return-water temperatures. Equinix and A2A's Milan project targets 225 GWh of annual heat recovery through 72 MW of heat-pump capacity. Microsoft and Fortum are developing one of the world's largest data-center heat-recycling schemes in Finland. Heat exchangers, recovery substations and controls gain value as operators seek standardized interfaces between cooling and heat-export systems. Thermal storage helps balance continuous data-center heat output against seasonal and hourly heating demand. High-temperature liquid-cooled AI systems can reduce the lift required from heat pumps and improve project economics. District heating is the largest external reuse pathway. Campus heating and industrial heat use provide site-specific alternatives. Brownfield adoption is constrained by low return-water temperatures, physical connection costs and distance from suitable heat demand. Waste heat recovery is increasingly evaluated during site selection and cooling-system design rather than added after construction.

Competitive and Strategic Outlook

Competition spans industrial heat-pump manufacturers, heat-exchanger suppliers, data-center thermal-management companies, district-energy utilities and specialized system integrators. Danfoss offers data-center heat recovery modules, heat pumps, heat exchangers and district-energy controls. Johnson Controls, Trane Technologies, Carrier and MAN Energy Solutions participate through large-scale heat-pump and thermal systems. Alfa Laval, GEA, Kelvion and Oilon provide critical heat-transfer and heat-pump technology. The market increasingly rewards vendors that can combine efficient heat capture with controls and prefabricated integration rather than sell individual components only.
Utilities and heat-network operators are equally important because many large projects require a long-term heat offtake agreement. Fortum, ENGIE Solutions and A2A are developing or operating data-center heat-recovery schemes at city scale. Equinix, Microsoft, AWS and other data-center operators provide the heat source and influence cooling-system design. Hewlett Packard Enterprise and Danfoss have also packaged heat recovery into modular data-center infrastructure. This indicates that heat reuse can move upstream into the data-center procurement process rather than remain a separate utility project.
Technology differentiation is increasingly linked to temperature. Systems that preserve higher coolant temperatures can reduce the heat-pump lift and improve coefficient of performance, making the recovered heat more valuable. Heat exchanger approach temperature, refrigerant choice, compressor efficiency, modularity, thermal storage integration and control of variable IT loads therefore influence total project economics. Vendors that can support both traditional low-temperature recovery and newer high-temperature liquid-cooled AI systems are positioned to address the widest installed base through 2032.
Europe is the principal early market for data-center waste heat recovery because three conditions are present simultaneously. There is a dense installed base of district-heating networks, policy support for recovered heat and rapid construction of high-density digital infrastructure. Nordic markets have the longest operating history because utilities already use low-carbon electricity, large heat pumps and centralized heat networks. Finland, Denmark and Sweden therefore provide the strongest technical reference base for heat-export design. The market is now expanding into France, Germany, Italy, Ireland, Switzerland and other European countries as cities seek lower-carbon heat sources and data-center developers face tighter efficiency requirements.
Regulation materially changes project economics and planning. The EU Energy Efficiency Directive requires facilities above 1 MW to use waste heat or another recovery application unless infeasibility is demonstrated. Installation-level assessments must consider local demand and district-network connections. This does not eliminate commercial constraints. It raises the probability that heat recovery is designed into new cooling plants even when the final heat-offtake agreement is signed later. Vendors that can provide heat-recovery-ready cooling interfaces, standardized substations and modular high-temperature heat-pump systems are therefore positioned to benefit before every site reaches full heat-export operation.
The project scale is also increasing. Equinix and A2A's Milan development is designed to supply enough recovered thermal energy for more than 21,000 homes. Fortum's Finnish infrastructure around Microsoft's campuses is being built as part of a broader regional heating transition. ENGIE and Equinix are using recovered heat from the PA10 data center in Saint-Denis, where heat pumps upgrade data-center water to support the local network and Olympic Aquatic Centre area. This mix of utility, colocation and hyperscale projects creates a broad purchasing base across heat pumps, exchangers, thermal storage, hydraulic equipment, controls and integration services.
North America has substantial technical potential but a smaller district-heating footprint. Adoption is more site-specific and often focused on campus heating, adjacent buildings or on-site thermal reuse. Asia Pacific combines major data-center growth with district-energy opportunities in selected cities, particularly where dense urban development supports centralized heating or industrial heat demand. In warmer regions, the strongest opportunity may come from converting waste heat into cooling or industrial use rather than space heating.
Recent developments confirm accelerating market activity. In September 2026, the European Commission opened consultation on minimum performance standards for data centers as part of its energy-efficiency package, with waste-heat reuse included among the environmental-performance priorities. In July 2026, Equinix and A2A announced a Milan heat-export project designed for up to 225 GWh of recovered heat per year, supported by four heat pumps with 72 MW of combined capacity and 6,000 cubic metres of thermal storage. In May 2026, Fortum started heat production at large heat-pump plants in Espoo and Kirkkonummi that will progressively integrate waste heat from Microsoft data centers as the facilities enter operation. In April 2026, Microsoft confirmed the second construction phase of its Finland data-center region. The associated Fortum heat-recycling scheme is expected to supply about 40% of the district-heating demand in the served area when fully developed. In February 2026, Alfa Laval published operating results from HeatChain data-boiler facilities in Finland, reporting 50 GWh of clean district heat delivered during 2025 with high-temperature liquid cooling and heat-transfer technology. In January 2026, Alfa Laval detailed the Odense data-center heat-recovery system, which captures about 100,000 MWh of heat annually for the local district-heating network, sufficient for roughly 7,000 homes.

Conclusion

The AI data center waste heat recovery systems market is growing rapidly as regulation, liquid cooling and utility-scale heat partnerships converge. Growth is driven by higher recoverable heat quality from liquid cooling, European waste-heat utilization requirements and district heating partnerships reaching utility scale. Industrial and high-temperature heat pumps form the largest value pool. Heat exchangers and recovery modules are critical enabling layers. District heating remains the leading reuse pathway. Europe is the largest early market. North America and Asia Pacific offer more site-specific opportunities. Continuous heat supply versus variable demand, low recovery temperatures and connection costs remain the key restraints. The market is projected to grow from USD 0.82 billion in 2026 to USD 3.17 billion by 2032 at a CAGR of 25.3%.
