The Eurovent Certified Performance (ECP) programme scope for Residential Ventilation (RAHU) applies to mechanical supply and exhaust ventilation units used in a single dwelling, as defined in EN13141-7:2010:
When a company joins the programme, all relevant units presented on the European market shall be certified. However an applicant/participant has three years to comply with the certify-all principle when entering the programme or when a new heat-recovery type is manufactured or sold by the applicant/participant. For more information on the certify-all principle, see Chapter II.3 of the Certification Manual.
Residential ventilation systems can provide fresh air ventilation, humidity control and improve indoor air quality in domestic buildings. Best suited for use in average and cold climates, systems are available in numerous sizes, designs and mountings, for a range of residential applications.
Residential ventilation systems typically comprise of supply and exhaust fans, heat recovery exchanger, outdoor and exhaust air filters, and an integrated control system. Components are usually housed within a compact casing, and connected to a ductwork system.
In the residential ventilation system programme the following heat recovery types are considered:
All heat recovery types are designed to pre-heat the supply air with waste heat from the return air. Category I air-to-air plate or tube heat exchangers (recuperative heat exchangers) are designed to transfer thermal energy from one air stream to another, passively, without any moving parts. Category II air–to-air rotary heat exchangers, (regenerative heat exchangers), are designed to transfer thermal energy via a rotating cylinder or wheel. Extract air-to-outdoor air heat pumps are designed to transfer thermal energy from one air stream to another via a heat pump. Depending on the system and application, the recovered energy can also be used to heat hot water systems too.
While exploring our certified products you’ll come across a number of technical terms relating to certification. The below definitions help explain the search criteria in our certified product directory.
Brand name of the manufacturer.
Listing of models with some common features.
Internal leakage class
Is the internal leakage class according to EN13141-7:2011. The classification goes from the best (A1, B1, or C1) to the worst (A3, B3, or C3).
Percentage internal leakage
Is the percent of air lost to internal leakage, according to EN13141-7:2011.
External leakage class
Is the external leakage class according to EN13141-7:2011. The classification goes from the best (A1, B1, or C1) to the worst (A3, B3, or C3).
Percentage external leakage
Is the percent of air lost to external leakage, according to EN13141-7:2011.
Airflow-pressure certified window
Is the URL providing the airflow / pressure curves.
Is the maximum flow reference pressure. It is the total unit pressure difference at which the maximum airflow rate is determined. Expressed at 100 Pa, unless declared otherwise by the manufacturer.
Is the declared maximum air volume flowrate, measured in m3/s. It is the air volume flow corresponding to the declared total pressure difference (PtUd), of the unit at the maximum setting for standard air conditions (20 °C, 101325 Pa).
Is the total pressure difference at reference point on the supply side. It is the reference point defined at ptUd/2 and 70% of declared maximum air volume flow. If this point cannot be set, pressure shall remain at ptUd/2 and airflow shall be adjusted just over.
Is the air volume flow rate at reference point on the supply side. Measured in m3/s.
Is the effective power input at reference point. Measured in W.
Is the specific electrical power input at reference point. Expressed as W/(m³/h).
Disbalance Ratio Nominal Condition
The disbalance ratio is calculated by the result in percentage of the difference (in absolute value), between extract airflow and supply air airflow at nominal conditions, divided by the maximum value between airflow extract or airflow supply.
Is the temperature ratio at reference point on the supply air side at point 1. Measured in percentage.
Is the A-weighted sound power level at reference point radiated through the casing. Measured in dB(A).
Is the A-weighted sound power level at reference point in duct connections at the supply. Measured in dB(A).
Is the A-weighted sound power level at reference point in duct connections at the extract. Measured in dB(A).
Is the A-weighted sound power level at reference point in duct connections at the exhaust. Measured in dB(A).
Is the A-weighted sound power level at reference point in duct connections outdoor. Measured in dB(A).
Is the temperature ratio at reference point on the exhaust air side at -15oC. Measured in percentage.
Is the disbalance ratio at Cold climate condition.
Is the air volume flow rate at Cold climate condition. Measured in m3/s.
Cold climate (true / false)
A true or false result indicating if the unit is design to operate at an outdoor temperature below -15oC.
Is the Specific Energy Consumption for ventilation per m2 heated floor area of a dwelling or building. Expressed as kWh/m².a.
Is the Specific Energy Consumption class. G is the lowest SEC class rating while A+ the highest.
Is the Annual Electricity Consumption. Measured in kWh/annum.
Is the average climate Annual Heating Savings. Measured in kWh/annum.
Is the cold climate Annual Heating Savings. Measured in kWh/annum.
Is the warm climate Annual Heating Savings. Measured in kWh/annum.
Is the aggregated general typology factors for ventilation effectiveness, duct leakage and extra infiltration.
Is the Control Factor. It is the correction factor for the SEC calculation, depending on the type of control that is part of the ventilation system.
Is an exponent that takes into account non-linearity between thermal energy and electrical savings, depending on motor and drive characteristics.
Filter class supply
Is the class of filter used in the supply, plus the percentage of particles it removes e.g. ISO ePM1 50%. Filter grades include:
• ISO ePM1 for particles 0.3 micron to 1 micron in size
• ISO ePM2.5 for particles 0.3 micron to 2.5 micron in size
• ISO ePM10 for particles 0.3 micron to 10 micron in size.
• ISO Coarse for particles 10 micron or larger.
Filter class exhaust
Is the class of filter used in the return, plus the percentage of particles it removes e.g. ISO coarse 60%.
