Components of comfort Air diffusion and comfort Generality Designing an air diffusion system means first making the right selection in order to guarantee comfort. Comfort depends on three main components : • The thermal component, • The aeraulic component, • The acoustic component. The thermal and aeraulic components These first two represent the area covered by the NF EN ISO 7730 standard, which specifies : • oom temperatures, according to the activity and r cladding, • discomfort caused by drafts, • the feeling of warm or cold walls, • tolerance of vertical temperature gradients.

Components of comfort The ASHRAE recommendations in terms of acoustic pressure (sensation perceived by the occupant) according to the use of the premises, provides overall comfort. The level of acoustic pressure in an area depends on the power levels (noise emitted by sound sources) : • from the diffuser (s) , • quipment operating ahead of it/them (air conditioner, e air processing unit, etc...) , • and sound sources in the premises. Next the attenuation in the premises is integrated into the calculation, to provide an overall acoustic pressure level. Level of acoustic presure (Lp) : ASHRAE...
