The design and implementation of a cabin - construction specially designed to protect people (e.g. machine operators) from ambient noise, consisting of a fully enveloping structure - being efficient in terms of sound insulation makes it necessary to involve constructions often very airtight and often having moderate heat loss.
The ventilation of a cabin is related to the need for health air renewal ventilation for the occupants and may contribute to their thermal comfort (in summer: if the air introduced into the cabin is fresh enough, in winter: if the air introduced into the cabin is warm enough).
The required ventilation flow rate is related to the number of occupants, to the potential thermal disspation of equipment installed inside the cabin (lighting, computer equipment ...), to the performance in terms of thermal insulation of the partitions of the cabin and to the acceptable inlet temperature gradient (difference between the temperature within the cabin and the temperature of the air of the ventilation system). The existence of a ventilation system in a cabin usually leads to the need to implement silencers (one for air inlet and one for the air outlet to limit the propagation of noise through these openings) and sometimes to have to silence the fan (especially for the acoustic comfort of the occupants of the cabin). The installation of booths in some particularly hot environments (in relation to climate, or due to the presence - close - of sources of heat like an oven or due to the existence of certain processes in the paper industry, the cardboard industry or glass manufacturing for example) may necessitate the implementation of air conditioning equipment.
