The hotels with low bedspace capacity can be provided with natural inlet ventilation. The air recycling rate in such premises is prescribed by the class of the hotel: for five-star hotels — 70 m3 /h ; 4**** — 60 m3 /h; 3*** — 40 m3/h ; 2**; 1* — 30 m3/h.
If a facility is served with natural ventilation only, you should consider that hermetical window panes provide the air flow rate not exceeding 6-7 m3/h, thus there is a necessity in additional ventilation devices with forced and controllable air intake. If a facility is not equipped with forced inlet ventilation system, it must be provided with appliances for outside air intake, placed at 2 m above floor level or higher.
In the smoking areas, minimum air recycling rate must be 100 m3/h (smoking in hotel rooms is forbidden since 2014 acc. to federal Law #15 and is allowed only in specially designed areas). To enhance the air recycling rate and to ensure the air cleaning from dust, tobacco smoke and other noxious substances you can use the air cleaning and disinfection systems with 100% air recycling.
Equipment: compact inlet ventilation system Breezer Tion O2 with air cleaning (up to 120 m3/h, HEPA-grade air filtration, air conditioning; individual setup in every room).
For smoking areas: air cleaner and decontaminator Tion Clever (up to 150 m3/h, H11-grade air filtration, disinfection efficiency 99.9%, tobacco fume and other noxious substances removal down to the prescribed standard levels)
