The efficiency of finding people in shopping centers directly depends on a comfortable microclimate. The better consumers feel, the more money they will leave here.
Ventilation requirements for shopping centers
Purpose of ventilation in shopping centers:
- Removal of impurities, stench, dust from the air;
- Ensuring air exchange;
- Providing a comfortable air temperature;
- Fresh air inflow in a mode convenient for visitors.
Ventilation of commercial premises should be easy to maintain and easy to manage, operate quietly and not blow in the face of employees and visitors.
Technical standards stipulate that each employee of the shopping center should have 60 cubic meters of clean air per hour, and for each visitor - 20 cubic meters.
For ventilation of the shopping mall, recirculation systems can be used, however, rooms with poisonous, dangerous, explosive and flammable substances, as well as with strong-smelling goods, should not be connected to them. The ventilation system supplies air from the street here.
To calculate the ventilation of a shopping complex, you can take the following indicators:
- 3.5 square meters of space per visitor in electronics stores, books, jewelry, sports, furniture;
- 2.5 square meters per customer in grocery stores and not previously listed.
Features of the design of ventilation of sales areas
The calculation of the ventilation of sales areas is based not only on the purpose and size, but also on the floor of the building. For example, it is known that most of the visitors gather on the ground floors. On the latter, there are fewer buyers.
Separate ventilation is provided for the halls selling food. The abundance of refrigerators and freezers requires intensive work of the supply and exhaust system. If the ventilation of the retail space is incorrectly installed or calculated, condensation will settle on the glass of refrigerated display cases, creating favorable conditions for the growth of fungi and mold.
In warehouses, the ventilation of the sales area is most often an exhaust system equipped with fire retardant valves.
Ventilation scheme for commercial premises and its calculation
As a rule, ventilation systems in shopping centers are combined with air conditioning and heating. This makes it more convenient to control the microclimate and simplifies the installation of air ducts. A central air conditioner, equipped with an outdoor air supply system, supplies them to the premises, and exhaust fans extract the used air from the premises.
