One of the main conditions for the operation of public buildings is to ensure air exchange. A large flow of visitors passes through public buildings (hotels, medical institutions, government agencies, cinemas, lecture halls) every day. To ensure optimal microclimate parameters, central air conditioning systems are installed (the optimal ones are chiller-fan coil units), supplemented by ventilation of the supply-exhaust system.
The specifics of air conditioning in public buildings
Public buildings are characterized by the following differences:
- multi-storey;
- long corridors on each floor;
- lift shafts and stairs between floors.
In addition, when calculating the air conditioning of buildings, it is necessary to take into account the purpose of the premises, different levels of heat and gas emission.
Air conditioning equipment in buildings provides the best microclimate performance and creates air movement between rooms. Sometimes this is necessary, since a number of rooms do not require air conditioning, but only ventilation.
Modern equipment allows you to heat the air during working hours of the day, at night only by turning on the ventilation system. The air conditioning system of a building is of great importance in creating fire protection for a building.
Building air conditioning schemes
A public building can be air-conditioned by a local or general exchange system.
Any type of air conditioner is used, depending on the number of storeys of the building and its architectural features. If the building is one-story, a roof-top rooftop or monoblock is installed.
In buildings converted from multi-room, multisplit systems are installed. Convenient and multi-zone systems controlled from a common console.
For example, if the air conditioning system of a building is based on a chiller (convenient for cinemas, conference rooms), the supply air volume and the recirculation volume can be pre-programmed. Indicators change depending on the air temperature outside and save energy.
All equipment is mounted in a special room or basement.
The public building is also air-conditioned with a central air conditioner. This solution is very convenient, for example, when designing an art gallery. The central air conditioner provides heat recovery as well as powerful air outflow from the room.
