What factors should be considered for the installation position of the air outlet in the fresh air system?
2023-04-26
For fresh air systems, more and more households are choosing to install them during decoration. The fresh air system installed in a home is usually equipped with fresh air ducts, which are then used to press the air outlet. The purpose is to use a fresh air fan for ventilation and then deliver it to our room through ducts and fresh air outlets. Therefore, there are certain requirements for the setting of air vents. The air inlet of the fresh air system is used to draw outdoor air into the room through the machine. The so-called fresh air intake meets the requirements, that is, the intake of the fresh air system we set up cannot be in a closed space.
You can choose to install the air inlet of the fresh air system in the open position on the exterior wall to meet the demand for fresh air intake. Non pollution means that there will be no pollutants near the intake of the fresh air system. For example, the kitchen exhaust pipe cannot be close to the intake of the fresh air system, as if there is a kitchen exhaust pipe, the captured smoke may be sucked in by the intake of the fresh air system. Therefore, the air inlet of the fresh air system should be away from the exhaust duct of the gas wall mounted furnace and the outdoor chimney. It also has some facilities that may emit oil fumes and dust. Avoid heat sources, even near fresh air outlets.
There should be no outdoor units with air conditioning near the new air outlet, as during operation, the outdoor unit dissipates heat and the radiated air quality is very poor. If the new air outlet is too close to the outdoor unit of the air conditioner, it may be to send heat into our room. The effectiveness of our indoor air treatment is not good. Fresh air is transported through pipes in the room. In addition, after the completion of indoor fresh air supply and exhaust design, it is necessary to add a suspended ceiling at the pipeline position to achieve aesthetic goals. The return air outlet for fresh air can be located on the same side of the bedroom and use the ceiling, but the supply and exhaust ports are located at both ends.
The indoor fresh air return port can be made into a diagonal line, and the indoor ceiling needs at least two sides. Only the fresh air outlet in the bedroom can be directly perforated on the wall to install a fresh air supply outlet, and the ceiling cannot be considered in the room. The new air volume can be calculated based on the number of residents with a capacity of 30 cubic meters per person, as well as the room area, space size, and ventilation frequency. The maximum value of both can be used to obtain the optimal indoor fresh air volume. A small amount of fresh air will weaken the effect of fresh air, while an excessive amount of fresh air will increase noise. Only a suitable amount of fresh air is the best.
