T欧洲联盟（EU）通过以下方式对通风设备进行监管： 法规 (EU) 1253/2014 (the “Ecodesign” Lot 21 measure). It sets binding minimum thermal efficiency and fan-power limits for units placed on the EU market, so any AHU or ERV sold in Europe must comply.
范围
适用于风机电功率达到以下数值的住宅及非住宅通风设备： 30 W 或以上。双向机组（送风＋排风）必须配备带热旁通装置的热回收系统（HRS）。
Minimum Heat Recovery Efficiency
| 设备类型 | Minimum thermal efficiency ηt | 加算基准 |
|---|---|---|
| 板翅／热转轮 HRS（非绕管式） | 73%（自2018年起） | E = (ηt − 0.73) × 3000 |
| 绕管（运行环路）盘管 HRS | 68%（自2018年起） | E = (ηt − 0.68) × 3000 |
效率加算 E 放宽了比风机功率限值，奖励高效率芯体。试验方法为 EN 308、EN 13053（空气处理机组）和 EN 13141-7（住宅机组）。该 效率试验标准文章 explains how ηt 已定义。
Specific Fan Power Limits
- 带 HRS 的非住宅设备：SFP整数（内部） capped around 800–1300 W/(m³/s) depending on flow.
- Residential bidirectional unit: about 450 W/(m³/s) at reference airflow.
- 所有设备（双用途除外）都需要多速或变速驱动；自2018年起要求具备过滤器报警信号。
What Designers Must Do
指定达到73%（绕管式为68%）的芯体，并备妥产品信息表。对于不允许交叉污染的关键通风，一种 膜芯体 是符合规范的非旋转选项。 EPBD 零排放建筑 push — efficient recovery is now table stakes in the EU market.
Labelling and Market Reality
The Ecodesign floors are not just paperwork; they reshape what can be sold. Because the efficiency bonus E relaxes the specific fan power limit, a unit with a 78% core gains compliance headroom over a bare 73% unit, which matters as fans are pushed to lower SFP. Manufacturers must publish a product information sheet documenting thermal efficiency and fan power, and that sheet is what a designer cites at spec time. For non-residential AHUs, EN 13053 governs how the recovery section is rated within the whole unit, including the pressure drop it adds. Residential bidirectional units face the same 73% logic but with a tighter SFP reference. In practice, specifying a membrane or high-efficiency plate core that clears 73% comfortably satisfies the regulation and aligns with the broader EPBD push toward zero-emission buildings, where efficient recovery is now expected rather than optional.
常见问题
What does EU Ecodesign Regulation 1253/2014 require?
Ventilation units above 30 W fan power must carry a heat recovery system meeting minimum thermal efficiency, 73% for plate or wheel and 68% for run-around.
How does higher efficiency help compliance?
An efficiency bonus relaxes the specific fan power limit, giving design headroom as fans are pushed to lower SFP.
Which test standards apply?
EN 308, EN 13053 for air-handling units, and EN 13141-7 for residential units.
Can a membrane core comply?
Yes. A non-rotating membrane core is a compliant option where cross-contamination control is required.
