The hotel is quite a com­plex object in terms of design­ing ven­ti­la­tion sys­tems. Any hotel con­sists of many rooms with dif­fer­ent pur­pos­es: liv­ing rooms, bath­rooms, kitchen. In 4 and 5 star rooms there are nec­es­sar­i­ly ban­quet and sports halls, bars, beau­ty salons, restau­rants, etc. And each room requires strict­ly defined micro­cli­mate para­me­ters.

Features of hotel ventilation systems

From prop­er­ly designed ven­ti­la­tion sys­tems, com­fort direct­ly depends, and, accord­ing­ly, the time spent by guests in the com­plex. That is why the hotel ven­ti­la­tion sys­tem must meet the fol­low­ing require­ments:

  • Effi­cien­cy. All air exchange reg­u­la­tions must be observed. In hotel rooms — 60 m3/h; in show­ers and bath­rooms — 120 m3/h; in con­fer­ence rooms at least 30 m3/h. In oth­er rooms, com­pli­ance with oth­er stan­dards is required, in accor­dance with the cur­rent SNiP and reg­u­la­to­ry doc­u­ments.
  • Noise­less­ness. Silence is one of the defin­ing require­ments, since the main num­ber of rooms in the hotel are bed­rooms.
  • Reli­a­bil­i­ty. Ven­ti­la­tion net­works and their equip­ment must func­tion 365 days a year and be avail­able for repair and main­te­nance.
  • Indi­vid­u­al­i­ty. Any solu­tions should allow the cre­ation of the most com­fort­able micro­cli­mate para­me­ters for guests in each indi­vid­ual room.

There are many require­ments for hotel ven­ti­la­tion. SNiP P‑L. 17–65 allows the cre­ation of a nat­ur­al ven­ti­la­tion sys­tem with an extract from the bath­rooms or toi­lets, if any in the rooms. In areas with an air tem­per­a­ture of ‑40 ° C dur­ing the cold sea­son, mechan­i­cal air inflow with its heat­ing and, if nec­es­sary, humid­i­fi­ca­tion should be pro­vid­ed. The same SNiP reg­u­lates the instal­la­tion of ther­mal cur­tains at the entrances to hotels locat­ed in areas with out­door tem­per­a­tures in win­ter below ‑15C°. http://www.youtube.com/watch?v=CPxZrtuiDHk

The most common schemes

The scheme of the ven­ti­la­tion sys­tem, first of all, depends on the cat­e­go­ry of the hotel. If the hotel has been assigned a cat­e­go­ry of 4 stars or more, then each room, regard­less of its cost, must be equipped with a forced ven­ti­la­tion sys­tem. The sup­ply and exhaust ven­ti­la­tion for high-end hotels is designed with fresh air sup­plied through air ducts from a cen­tral­ized sup­ply unit to each room, and the exhaust is car­ried out from bath­rooms, bath­rooms and show­ers.

In hotels of low cat­e­gories (3 stars and below), it is allowed to cre­ate a nat­ur­al ven­ti­la­tion sys­tem with the influx of fresh air mass­es into the rooms through open vents or auto­mat­ic sup­ply valves installed on the win­dows. The removal of pol­lut­ed air is car­ried out through the hoods in the bath­rooms.

Device and design features

Most often, in 4–5 star hotels, a solu­tion is used with cen­tral air con­di­tion­ing, and the instal­la­tion of chillers and fan coil units. This option allows you to ensure that all require­ments for ven­ti­la­tion and air con­di­tion­ing of hotel premis­es are met with­out vio­lat­ing the design of the build­ing.Hotel vent device.  systems

The chiller, togeth­er with the exhaust fan for extract­ing the exhaust air, is locat­ed on the roof of the hotel build­ing, which ensures the qui­et oper­a­tion of the equip­ment for the guests of the com­plex. Fan­coil units locat­ed behind the false ceil­ing allow you to set the opti­mal para­me­ters of the micro­cli­mate in the rooms. In such a sys­tem, an impor­tant role is played by the cen­tral air con­di­tion­er, usu­al­ly locat­ed in the base­ment of the build­ing. For water cir­cu­la­tion, a pump­ing sta­tion is used, which is most often locat­ed on the roof of the hotel com­plex. This solu­tion has sev­er­al unde­ni­able advan­tages:

  • All hotel ven­ti­la­tion stan­dards are observed regard­ing tem­per­a­ture, humid­i­ty and air flow rate.
  • This scheme is the cheap­est, as it works on water. This allows you to sig­nif­i­cant­ly reduce the cost of main­te­nance.

Ventilation equipment for mini-hotels

The scheme of ven­ti­la­tion and air con­di­tion­ing of rooms, made on the basis of an exhaust ven­ti­la­tion fan, a cen­tral air con­di­tion­er, chillers and fan coil units, has shown itself per­fect­ly in large hotels. In mini-hotels, most often, to cre­ate a com­fort­able micro­cli­mate, sup­ply and exhaust devices of the required capac­i­ty are installed, togeth­er with a mul­ti-zone air con­di­tion­er.

Such instal­la­tions ven­ti­late, heat, and also fil­ter the air com­ing from the street for sub­se­quent dis­tri­b­u­tion through­out the hotel premis­es. To reduce the cost of space heat­ing, sup­ply and exhaust equip­ment with air recov­ery is most often used.Supply and exhaust equipment with air recovery

The use of mul­ti-zone air con­di­tion­ers makes it pos­si­ble to cre­ate the most com­fort­able micro­cli­mate in each room with­out vio­lat­ing the design of the facade of the build­ing.

Before cre­at­ing a com­plex and branched ven­ti­la­tion net­work in a hotel com­plex, com­plex cal­cu­la­tions are required. That is why to design and install a com­pe­tent and effi­cient sys­tem for cre­at­ing an opti­mal micro­cli­mate, it is best to turn to pro­fes­sion­als.
