SLB (31 Aug) agreed to acquire heat-exchanger group Kelvion from Apollo and Triton for about $3.4bn in cash plus $0.7bn of assumed debt—roughly $4.1bn in enterprise value, or about 11× estimated 2026 EBITDA before synergies; closing is targeted for the first half of 2027
China’s second 2026 HFC mid-year quota-adjustment window closed on 31 Aug, and MEE’s consultation on the 2027 ODS/HFC quota drafts closed on 3 Sep; the next hard date is 31 Oct for 2027 quota and initial-transfer filings
Mechanical-industry standard JB/T 15555-2026 for ultra-low-ambient air-source heat-pump (chiller) units took effect on 1 Sep, covering motor-driven vapour-compression machines that can still make hot or chilled water at outdoor temperatures down to −35°C
Daikin UK and Eurovent Certification (2–3 Sep) listed 65 residential multi-split and Multi+ air-to-air combinations on the UK MCS Product Directory—the first A2A listings via the Eurovent route, and a prerequisite for BUS eligibility once MCS coverage of the technology is complete
IFA Berlin opened 4–8 Sep; Midea showed its R290 residential series (H-Pack and PortaSplit), claiming about 10% higher energy efficiency, with PortaSplit scheduled to move to R290 in 2027
Policy
Policy & Regulation
The Chinese quota calendar has moved from consultation to filing. The second 2026 HFC mid-year adjustment window closed on 31 August. MEE’s covering letter on the 2027 ODS and HFC quota drafts—posted 24 Aug, comments due 3 Sep—is now closed. Industry write-ups of those drafts still report a freeze of HFC production and use totals at 2026 levels (1.853bn tCO₂ production quota, 0.895bn tCO₂ domestic-use quota, 0.10bn tCO₂ import quota), plus a semiconductor-special increment of 150 t of HFC-236fa. Treat those figures as draft until the final notice. 31 October remains the date for 2027 quota and initial-transfer applications; two in-year adjustment windows are planned for 30 Apr and 31 Aug 2027.
Two English-speaking jurisdictions are still about how heat pumps get onto sites, not about a new thermodynamic rule. California SB 222 remains on Governor Newsom’s desk after being presented on 30 Aug; he has until 30 Sep to sign or veto. It would standardise non-discretionary permitting for heat-pump HVAC and heat-pump water heaters in existing homes, not new construction. In Great Britain, Daikin’s MCS directory listing (below) is the first product-level step toward air-to-air BUS support that more than 50 MPs pressed MCS and UKAS to unlock in week 32. Product listing is required; voucher issuance is not yet open. The EU’s 1 Jan 2027 GWP<150 placement limits for defined self-contained AC/heat-pump categories up to 50 kW are unchanged.
Markets
Market & Industry
SLB’s Kelvion agreement is an infrastructure-stack purchase, not a chiller-OEM bolt-on. The Houston group is paying about $3.4bn cash and assuming about $0.7bn of debt for a century-old heat-exchanger house whose 2026 revenue is guided at $2.3–2.4bn and adjusted EBITDA at $350–400m. Data centres are already Kelvion’s largest and fastest-growing end market, guided at $1.2–1.3bn of 2026 revenue; heat pumps, renewables, carbon capture and process duties sit beside that. SLB says the deal more than doubles its revenue opportunity per gigawatt of delivered data-centre capacity and targets $4.5–5bn of combined data-centre revenue in 2028, with about $120m of annual EBITDA synergies within three years. Closing still needs regulatory approvals and is aimed at H1 2027. For HVAC/R bid teams, the counterparties on plate, shell-and-tube and dry-cooler packages in AI halls may sit inside an oilfield-services group rather than a traditional refrigeration OEM.
On the residential side of the same week, Chinese brands used IFA Berlin (4–8 Sep) to push hydrocarbon SKUs into Europe rather than to restate the China cooling year. Midea’s R290 series—H-Pack and PortaSplit, with PortaSplit slated for R290 in 2027—is a retail-channel answer to the EU’s 2027 self-contained GWP<150 step. That is a different stack from the commercial VRF R32 platforms still shipping (Clivet’s CVT9, covered in week 32). The China-market context is a stock market, not a volume boom: trade write-ups of the 2026 cooling year put global room-AC shipments down and frame data-centre cooling as the structural increment. Treat IFA claims as launch copy until Eurovent or equivalent numbers are on a nameplate.
Tech
Technology & Demonstrations
JB/T 15555-2026 is now the mechanical-industry product standard for ultra-low-ambient air-source heat-pump (chiller) units. Published 13 Feb 2026 and in force from 1 Sep, it applies to motor-driven vapour-compression machines that use air as the heat (or cool) source and can still produce hot or chilled water at outdoor temperatures of −35°C or above. That sits below the −25°C / −30°C band commonly cited for GB/T 25127.1-2020 low-ambient commercial units and NB/T 11505-2024 cascade heating units. For Northeast and Inner Mongolia tenders, the practical change is the citation: type-test reports and procurement specs written to the older low-ambient GB line should be checked against the new JB/T before winter-2026/27 bid packages freeze. The text covers type, basic parameters, technical requirements, test methods, inspection, marking and packaging; it is an industry standard, not a GB mandatory.
Gree’s late-August CMIF identification of a large-lift cooling-and-heating screw cascade high-temperature heat pump was followed this week by a 1 Sep product note. The claimed rating condition is 7°C chilled water with 130°C hot water, a lift of 130 K, and a combined COP of 3.36 versus a boiler-plus-chiller baseline that Gree puts at about 60% energy savings. The architecture is described as a dual-circuit, four-stage compression cascade. A battery-plant retrofit is cited with more than 1.03 GWh of annual electricity saved. These are manufacturer and identification-committee figures, not an independently published performance map; charge, part-load, defrost and the actual steam-side interface should be requested before the machine enters a process-heat model. GB/T 18837-2026 for multi-split units remains a 1 Nov event, two months after this JB/T.
Daikin’s MCS listing is a certification-pathway story, not a new outdoor unit. Eurovent, acting as an MCS certification body, transferred already-certified performance data for 65 residential combinations: 45 multi-split (one outdoor with two to five wall indoor units) and 20 Multi+ (up to four indoors plus a DHW tank). No additional product re-test was required. The systems use the Perfera indoor. MCS product listing is a required step toward air-to-air eligibility under the Boiler Upgrade Scheme, Warm Homes: Local Grant and related funds—once MCS certification for the technology itself is complete. Installers quoting BUS on the back of this week’s announcement would be ahead of the scheme. Specify the exact certified combination; a near-SKU is not listed.
Analysis
Why It Matters
For data-centre and industrial cooling: thermal management is being bought by infrastructure groups, not only by HVAC OEMs. SLB–Kelvion follows Madison Air–ebm-papst (week 34) in pulling heat transfer, airflow and modular plant into a capacity-delivery story. Specification teams should ask who owns the cooler selection, the water-side fouling case and the spare-parts obligation after closing—not only which logo is on the coil.
For refrigerant and quota strategy: China’s 2027 drafts should still be read as freeze-plus-reallocation until the final notice. The operational task this week is the 31 Oct filing, not a new Kigali step. In Europe the two-track shelf is unchanged: R290 at IFA for self-contained residential, R32 still on commercial VRF, and MCS beginning to catalogue air-to-air without yet paying for it.
For project owners: this week’s friction was clocks and catalogues. California permitting is unsigned, UK air-to-air grants are not voucher-ready, and JB/T 15555-2026 is in force while GB/T 18837-2026 is not. Treat Kelvion revenue guides, Gree’s 7/130°C COP and Midea’s 10% IFA claim as screening inputs; require envelopes, independent maps and the exact certified SKU before they enter a financial model.
Apply the signal: decide whether direct exchange, condenser recovery or a heat pump fits the site before selecting a catalogue unit. The refrigeration waste-heat recovery guide provides the measurement and comparison sequence.

大金的 MCS 上架是认证路径新闻，不是一台新室外机。Eurovent 作为 MCS 认证机构，把已有认证性能数据转入目录，覆盖 65 组住宅组合：45 组多联（一台室外配二至五台壁挂内机）和 20 组 Multi+（最多四台内机加生活热水罐），无需再做产品复测，内机为 Perfera。MCS 产品上架是空空热泵日后进入锅炉升级计划、Warm Homes: Local Grant 等相关资金的必要步骤——前提是 MCS 对该技术本身的认证已经完成。凭本周公告直接报 BUS 报价，会超前于计划。必须指定已认证的精确组合；相近 SKU 并不在目录中。
研判
影响判断
对数据中心与工业冷却：热管理正在被基础设施集团买下来，而不只是被暖通主机厂买下来。SLB–Kelvion 接在第34周 Madison Air–ebm-papst 之后，把传热、气流和模块化工厂并进“按容量交付”的叙事。规范团队应问清交割后冷却器选型、水侧污垢工况和备件义务归谁——而不只看盘管上的徽标。
