Canton Fair 2026: What the 140th Fair Signals for HVAC Controls

Key Points

• The 140th Canton Fair opened in Guangzhou on October 15, 2026 — its 70th anniversary edition — with more than 32,000 exhibitors and roughly 340,000 overseas buyers expected across three phases running to November 4.
• In the appliance and HVAC halls, presence-sensing AI replaced voice control as the headline feature: millimeter-wave radar now adjusts airflow to where people actually are.
• Vendors report AI-driven energy savings of 30–50%, but trade reporters on site noted these figures depend on test conditions — the executable control layer decides real-world results.
• Whole-scene systems (photovoltaic, storage, heat pump, hot water as one micro-grid) displaced single-product displays, and buyer conversations shifted from price toward local adaptation, standards, and delivery capability.
• For component buyers, the fair’s clearest message: sensing-rich, market-adapted, protocol-open control hardware is what the next procurement cycle will specify.

The Canton Fair is the largest recurring snapshot of what China’s HVAC and appliance supply chain intends to sell over the next two to three years. This year’s edition — the 140th, and the 70th anniversary of the fair — opened on October 15 in Guangzhou with more than 32,000 exhibitors and roughly 340,000 overseas buyers expected over its three phases. Walking the coverage of the appliance and climate halls, one theme is impossible to miss: the control layer has become the product story. Here is what it signals for anyone specifying, buying, or manufacturing HVAC controls.

The Fair in Numbers

Signal 1: Sensing Has Moved Into the Room

The defining demonstration this year was an air conditioner that reacts before anyone speaks. Midea showed millimeter-wave radar fused with an AI temperature-control system that senses temperature, humidity, occupancy, and air quality in real time, then redirects airflow to follow the person in the room. Changhong’s human-sensing unit quoted hard numbers: 6-meter detection range, a 120-degree sensing field, over 97% human-recognition accuracy, and sub-second response.

For the controls industry, this is not a gadget story. Presence-aware comfort is an occupancy-based control loop — exactly the architecture that demand-controlled ventilation has used in ducts for years, now migrating to the room. It requires sensors that were optional yesterday, and actuators that can execute fine modulating steps reliably. Our overview of indoor air quality and ventilation control describes the duct-side version of this loop; the fair suggests the room-side version is becoming mainstream.

Signal 2: AI Savings Claims Need a Measured Baseline

Energy numbers were everywhere. Midea stated its AI algorithms cut real energy consumption by up to 30–50% without sacrificing comfort; Haier’s whole-home “AI large HVAC” scheme — photovoltaic, storage, heat pump, and water heater running as one micro-grid — was presented with around 40% annual energy-cost savings.

Credit where due, but the sharpest line in the fair coverage came from Jiemian News reporters on site: these figures still depend on test conditions, comparison baselines, and the actual operating environment. That caution matters for procurement. An AI strategy is only as good as the hardware that executes it — if the valve actuator hunts, the damper overshoots, or the thermostat’s control output is coarse, the algorithm’s plan never reaches the physics. Real savings live at the bottom of the loop: the valve actuator, the damper actuator, and the thermostat that closes it. When a vendor quotes a savings percentage, the right follow-up question is which test standard, which baseline, and which actuation hardware.

Signal 3: Buyers Now Source Scenes, Not SKUs

The biggest booths stopped displaying products and started displaying systems. Haier’s exhibit chained photovoltaic input, storage scheduling, heat-pump operation, and hot-water recovery under one energy-management brain, switching strategies by season, sunlight, and tariff. Gree’s photovoltaic direct-drive air conditioner — stated DC conversion efficiency of 99%, stable operation at 52°C ambient, deployed across 35 countries — drew buyer queues.

The reporting from the fair floors describes the same shift on the buyer side: conversations that used to start with unit price now start with local adaptation, long-term delivery capability, and after-sales support. One practical consequence for the component tier: integrators and brand owners increasingly want a coherent terminal-control layer — thermostats, actuators, sensors that share signal conventions and can be branded together — rather than a scattered bill of materials. That is the work of an OEM/ODM controls partnership, and it is why the fair’s system-level pitch reaches all the way down to the actuator.

Signal 4: Market-Adapted Design Beats One Catalog

Europe ran through the conversation repeatedly. A Greek purchaser told CCTV+ that European buyers now scrutinize design and technology as much as price, highlighting new air-conditioner panels with 360-degree airflow and noting concrete progress in heat-pump capacity and technology. A Polish buyer with years in the air-conditioning trade said Chinese brands have matured to precisely match European requirements.

Adaptation showed up in engineering details too. Midea described a “2+X” strategy — energy efficiency and durability as the fixed two, with an X of market-specific variants — including no-screw mounting solutions designed for European buildings where old structures and rental tenancies forbid permanent installation. For controls, the parallel is direct: wiring conventions, signal types, and even thermostat interfaces differ by market. A supplier who can hold one platform and flex the per-market variant (as with thermostat selection across system types) is worth more than one who ships a single global SKU.

Signal 5: Specifications Are the New Price Talk

Underneath every trend above sits one procurement reality: the questions buyers ask have moved up the stack. Standards maturity, protocol openness, delivery stability, and joint development are now on the table at the fair itself — not just in post-fair emails. For controls buyers, we would translate the fair’s signals into a four-line checklist for any supplier meeting:

• Protocol: will devices expose their points on open buses (BACnet MS/TP, Modbus) without a proprietary gateway? Our field guide to commissioning BACnet MS/TP actuators shows why this is decided at the drawing board, not on site.
• Executable precision: can the actuation layer hold the modulating position the algorithm asks for?
• Market variants: can one platform flex to your market’s voltages, signals, and installation realities?
• Verified claims: which test conditions stand behind every efficiency number?

Outlook

Two editions ago the fair’s climate halls were selling cooling capacity; this year they are selling sensing, decision-making, and integration. The direction is consistent with the market forecasts covered in our recent review of the smart HVAC controls market — high single-digit annual growth, concentrated in connected and retrofit-friendly hardware. The fair adds the qualitative detail the forecasts lack: the next procurement cycle will be specified in terms of sensing capability and system fit, and the suppliers who speak that language at the component level will carry the conversation.

Work with DANRENS

The fair’s signals all land on the terminal control layer: thermostats, valve and damper actuators, and sensors that sense precisely, modulate reliably, and speak open protocols. DANRENS manufactures exactly that layer, with OEM/ODM support for market-specific variants. Request a quote or ask an engineering question.
