Design and calculation of the ventilation system in the dining room

There are special requirements for the design of the dining room ventilation. Particular norms are explained by the high level of humidity and temperature, the presence in the air of impurities from detergents used when washing dishes. Ventilation provides not only comfort for employees, but also safety, because the abundance of oils and fats, coupled with high air temperatures create a fire hazardous environment. Therefore, it is necessary to calculate the ventilation of the dining room inflow-blowing system.

Dishwasher ventilation in the dining room

The dishwasher has very humid air, which, penetrating into colder rooms, causes condensation to form, including detergents. In this regard, galvanized air ducts quickly fail. The dining room ventilation project involves the use of stainless steel or aluminum pipes, which are mounted on a site 7 meters from the hood.

Ventilation of the brewhouse in the dining room

It produces a lot of heat, fat and sometimes soot. Therefore, in the dining room ventilation project, it is necessary to lay a powerful exhaust hood. An important point in the design of the dining room ventilation is the shape and size of the exhaust hood. As a rule, it is not chosen by specialists in this field, therefore, the hood operation efficiency can be reduced.

Since the air ducts in the dining room can become very hot, they should be insulated from walls and combustible surfaces.

When designing the ventilation of canteens in the workplaces of the staff, mobile shower units are installed that evaporate the smallest droplets of water and enhance the effect of ventilation.

To prevent hot air and steam from entering the brewhouse for visitors, the ventilation system in the dining room is equipped with air curtains without changing the air temperature. In some cases, air is created in the dining room. For this, the power of the air flow entering the room is set higher than the power of the air discharged from the room. This creates excessive pressure, preventing the spread of kitchen odors in the dining area.

Features of the dining room ventilation system

When calculating the ventilation in the dining room, it is necessary to take into account the need to keep the systems clean. For this, the ventilation system in the dining room is equipped with additional filters, as well as:

  • Grease separators;
  • Drainage mounts;
  • Inspection windows to check the cleanliness of the air channels;
  • All flange gaskets are made of non-greasy materials;
  • The walls of the ducts should be easy to clean and have no ribs.
