Eco-Design explanation

Energy efficiency class​

The energy efficiency index is calculated based on the annual power consumption of the hood at the optimum operating point and the nominal electrical power consumption of the lighting system.
This is a ratio calculation where you set the calculated annual consumption for the product (AEC) against a standard consumption (SAEC). Where 100 corresponds to the product having the same consumption as the standard unit, so the lower the number the better. The difference is then translated into a letter classification.
The starting point is an average usage time for the light of 2 hours per day, and an average usage time for the hood of 1 hour per day. If the hood has a consumption in switched off mode / standby mode, this is added.

 

 

 

 

 

 

Class for hydraulic efficiency​

 

 

Roughly speaking, the most efficient point for the extractor hood is calculated here, where the air volume is kept up against the static pressure difference and current electrical consumption.

 

 

 

 

 

 

 

Lighting
efficiency class​

 

 

Here, the amount of light indicated in lux at the hob is kept against the available energy consumption.

 

 

 

 

 

 

Grease filtration
efficiency class

 

 

This indicates how large a proportion of the total amount of fat is collected in the filter.
 
It should be pointed out that the filter is defined as being removable parts of the hood, so by e.g. to make the glass plate on the Metz removable, this is included in the filter.​

 

 

 

 

 

Sound power level​

 

 

Here it is important to point out that previously the sound pressure was specified, which is typically lower than the sound power.
 
Sound power is measured in Watts (equal to loudspeakers) but given in dB(A).
 
The sound pressure is measured in pascals with a microphone (typically at a distance of 1 m) and is indicated accordingly in dB(A).

 

 

 

 

 

Annual energy consumption

 

The calculation is based on: The light is used for 2 hours
daily.
 
The hood itself is used for 1 hour a day, where the starting point is FDE - the point where the hood has the best efficiency, i.e. the largest air volume in relation to pressure drop and electrical consumption.
