Overview
EN 16297-2:2012 is a CEN European Standard that defines the procedure for calculating the Energy Efficiency Index (EEI) of glandless standalone circulators (rotodynamic pumps designed to operate independently). Prepared under mandate to support EU ecodesign requirements, this part complements EN 16297‑1 and specifies how to measure part‑load performance, compute an average compensated power input and derive the EEI used for compliance, product data sheets and procurement.
Key topics and requirements
- Scope: Applies to standalone circulators; units without pump housings must be measured in an identical pump housing intended for use.
- Measurement basis: Uses part‑load operating points and a defined load profile to calculate the average compensated power input (PL,avg).
- Load profile (annual operating hours weighting):
- 100% flow: 6% of hours
- 75% flow: 15% of hours
- 50% flow: 35% of hours
- 25% flow: 44% of hours
- Part‑load test procedure:
- Determine Href at each part‑load point on the reference control curve (see EN 16297‑1).
- Select and set a control curve close to the reference control curve and reaching (Q100%, H100%) within the H100% tolerance (defined in EN 16297‑1).
- Adjust the system curve to obtain the part‑load operating points and measure power.
- If multiple control curves meet the (Q100%, H100%) tolerance, it is recommended to calculate PL,avg for more than one curve and use the lowest PL,avg.
- Calculation:
- PL,avg is computed by weighted averaging of compensated power inputs at the defined load points (weights above).
- A calibration factor for standalone circulators is specified (given in the standard as 0.49).
- EEI is calculated from PL,avg, the applicable reference power (Pref,ref) and the calibration factor (see clause 6.2.5).
- Safety and performance references: EN 16297‑1, EN 809 and EN 60335‑2‑51 apply.
Practical applications and users
- Pump manufacturers: to rate products, prepare datasheets and demonstrate compliance with EU ecodesign rules.
- Test laboratories: to carry out standardized EEI testing and provide certified results.
- HVAC designers and specifiers: to compare circulator efficiency and select suitable products for energy‑sensitive installations.
- Regulatory bodies and procurement: to enforce or require EEI thresholds under Commission Regulation (EC) No 641/2009 and related ecodesign legislation.
- Energy auditors and consultants: to evaluate system-level savings potential by replacing inefficient circulators.
