In the application of this standard the following terms apply:
3.1
kitchen ventilation hood

the part of a mechanical ventilation system enclosing a space for kitchens for supply air and exhaust air, can

be equipped with integrated ceiling in accordance with prEN 16282-3
NOTE The lighting device is an integral part.

The purpose of kitchen hoods is to remove the heat, smoke, effluent, and other contaminants. The thermal plume from

appliances takes up the contaminants that are released during the cooking process. Room air replaces the void created by

the plume. If convective heat is not removed directly above the cooking equipment, impurities will spread throughout the

kitchen, leaving discoloured ceiling tiles and greasy countertops and floors. Therefore, contaminants from stationary local

sources within the space should be controlled by collection and removal as close to the source as is practical.

---------------------- Page: 8 ----------------------
oSIST prEN 16282-2:2011
prEN 16282-2:2011 (E)

Appliances contribute most of the heat in commercial kitchens. When appliances are installed under an effective hood,

only the radiant heat contributes to the HVAC load in the space. Conversely, if the hood is not providing sufficient C&C

(Capture & Containment), convective and latent heat are ‘spilling’ into the kitchen thereby increasing both humidify and

temperature.

Capture efficiency is the ability of the kitchen hood to provide sufficient C&C at minimum exhaust flow rate. The remainder

of this chapter discusses the evolution and development of kitchen ventilation testing and their impact on system design.

5.1 General remarks

Insofar as nothing to the contrary is stipulated, the requirements are checked by inspection and/or measuring.

Air containing fumes emitted from kitchens such as, for example, warm kitchens, portioning rooms, food

distribution areas, serving area (also in dining room), crockery and washing rooms shall be treated by means

of an effective fume separation before it enters the air ducts.

In commercial kitchens, hoods complying with prEN 16282-2 or ceilings complying with prEN 16282-3 are to

be employed for ventilation.

Hoods and their components (lightings, outlets, room ceilings, etc.) shall be arranged over the entire area of

the rooms in question. For room ceilings materials shall be used according to Table 2.

It is recommended, that a secure sensor port which can be easily accessed once installed should be provided

to measurethe differential pressure in the outgoing air area. The default dimension for this port is either an

external diameter of 4 mm or a round sensor aperture with a diameter of 12 mm. present

5.2 Arrangement above the kitchen equipment/hood dimensions

The exterior dimensions of hoods are determined by the dimensions of the equipment/equipment units

situated underneath the hood.

Figure 1 — Hood dimensions
5.2.2 Suspension height

During fitting, the fitting instructions are to be observed for any fitting mounts required.

Suspension height

The recommended suspension height of installation for a hood (lower edge of the hood, see figure 1 and 2) is

2.0 m above floor level. The minimum height shall be 2.0 m and the maximum shall be 2.5 m.

Installation heights deviating from this are possible for special function hoods (grill hood, bar hood/counter

hood).The height of the canopy is often governed primarily by the ceiling height. The top should project into

the ceiling by a minimum of 0.3 m to allow the false ceiling trim to be attached.

5.2.3 Hood dimension

Hood length/width shall be configured so that an overhang of at least 0.3 m extending beyond the outer edge

of the cooking equipment is ensured. For equipment with front doors (ovens, hot air steamers) an overhang of

at least 0.6 m shall be observed. Installation lengths/heights deviating from this are possible for special

function hoods (grill hood, bar hood/counter hood).
---------------------- Page: 13 ----------------------
oSIST prEN 16282-2:2011
prEN 16282-2:2011 (E)

If a suspension height of more than 2.0 m is taken as a basis, the configuration of the hood length and hood

width shall take into account that these dimensions need to be increased to cater for the lateral opening angle

(see Fig 1) of 15°.
5.2.4 Hood height/collection area
A minimum height of 0.4 m shall be observed.

The volume of the collection area shall be as large as the airflow volume to be extracted per second. For

hoods that are arranged over equipment that generates a high quantity of fumes (kettle, fryers etc) the hood

height and the collection area are to match the equipment. This does not apply to special function hoods (grill

hood, bar hood/counter hood).
5.2.5 Infillpanel

The height of the canopy is often governed primarily by the ceiling height. The underside of the canopy should

be located between 2.0 m and 2.1 m above the finished floor level, the top should project into the ceiling by a

minimum of 0.25 m to allow the false ceiling trim to be attached (figure 2).
Access panel should be opened without a tool.

5.2.6 Special function hoods (grill hood, bar hood/counter hood)

The grill hood is permitted to be suspended at a maximum 1.8 m from the upper edge of the hood to the

finished floor.

The grill hoods are not permitted to be suspended at heights that exceed 1.2 m from the lower edge of the

collection area to the finished floor and are to have a rear wall as well as a two-sided wall up to the upper

edge of the equipment unit.

The distance between the lowest edge of the separator and the top of the cooking surface should be 0.45 m

minimum. This is to avoid the risk of excessive temperatures or fire in the separator which could cause the
