One of the most important hygienic indicators of the effectiveness of indoor ventilation systems is the rate of air exchange in the room. This indicator defines the quantitative ratio of the weight of the air entering and leaving the room, within a certain period of time. Replacement of the air mass inside buildings and various structures is called air exchange.
When is it necessary to have a protocol of air exchange ratio?
- This document must be presented to operating organizations in various spheres of activity when they are inspected by inspectors of consumer supervision and fire supervision;
- In the process of licensing the work of institutions. These institutions include: educational, medical and pre-school institutions;
- During commissioning of facilities in which the ventilation system is an integral part.
Calculation of the air exchange rate in the room.
When designing and commissioning ventilation systems, an accurate calculation of air exchange is one of the main goals. The air exchange is determined by the amount of air volume supplied or removed from a room per unit of time. In most cases, air exchange is measured in cubic meters per hour. The value reflecting the amount of replacement of old indoor air with new air within one hour is called the air exchange rate. This value is calculated in accordance with established norms of air exchange for different rooms, prescribed in GOST and SNiP. The measurement process is based on the amount of fresh air needed, which assimilates excess moisture and conserves thermal energy in a particular room.
The company Aercaste works in this field all over Ukraine. In Nikolaev, Odessa, Kherson there are many companies where we have successfully accomplished our tasks. We measure the rate of air exchange in a variety of manufacturing facilities, taking into account all the necessary parameters. Depending on the purpose of the premises (residential, industrial, public), the ratio of air exchange may differ significantly. Therefore, the air exchange rate is calculated taking into account:
- The level of air exchange present in the room, created naturally;
- The number of mechanical ventilation systems present;
- The total amount of heat produced by the equipment installed in the room;
- The number of occupants or occupants in the room;
- The humidity of the air and the temperature;
- A number of different contributing factors.
Trust the calculation of air exchange in the room should be experienced professionals.
Employees of the company “Aercaste” having impeccable reputation in Ukraine and a huge list of accomplished works in Nikolaev, Odessa, Kherson, related to the calculation of the necessary air exchange in the room, will help you to achieve the following results:
- Ensure maximum hygienic conditions for people in the room, due to the optimal effective calculation of air ventilation;
- Eliminate the detrimental effects of harmful substances emitted during production or combustion;
- To use the installed ventilation systems more economically and efficiently;
The result of the work of Aercaste specialists.
After the work has been completed and the calculation of the air exchange rate, the customer will have a protocol of the air exchange rate in the rooms. In the future, the data from this protocol can be used when drawing up acts of inspection of ventilation and entering data in the certification of ventilation systems.
The protocol shall include the following data:
- The object where the measurements were made;
- The time and conditions of the work;
- The devices used, by means of which measurements were carried out;
- Calculated volumes of a single room;
- Data on the air velocity in the measured vents;
- The existing rate of air exchange;
- The required air volume or rate of air exchange in accordance with current regulations;
- The final part, which draws a general conclusion about the compliance of the existing air exchange rate with the data specified in the regulatory documents.
