Questions about a homemade ventilation system
Greetings. He embodied (he did everything himself, except for the holes in the walls, therefore not quickly) conceived, that is, a 500-caliber caliber on the balcony set 18 m on the room2, in front of her flk preview. Slowly ask questions, please read as much as possible.
Knowing that there are still rooms in need of ventilation, I did not risk overpriced performance. Feeling - the first speed to the room is enough for airing (5 points out of five) and noise. There is no discomfort during the day. In the night silence is not very pleasant (we do not sleep in the room).
Everyone at home likes it, now I’m thinking how to proceed further:
- A silencer will be needed of course.
- In the hall slotted vent. grate. I think to direct the flow forward and to the ceiling. Does it need an adapter or a static pressure chamber?
- And the worst thing is the hub. Drill three holes 160 ideally. Through them I enter the corridor. There, put shutters on each pipe and adapters on a rectangular plastic. Subsequently, you can close the box and adjust as necessary through the hatch.
- There are three small rooms. How to correctly position the grilles (or diffusers) in them? And which ones?
The first room is the smallest and most stuffy therefore. In it, the son of a student sleeps a couple of weeks once a year. Studying in Moscow. I don’t know, maybe she won’t do anything in it ... The second is the bedroom of two adults. In the third son, a teenager, sleeping with an open window, a bed by the window. I think there you still need to drag the pipe.

Good afternoon! The standards for the design and installation of ventilation systems are regulated SNiP 41-01-2003. The document, including applies to single-family low-rise buildings (cottages).
The rules established that the ventilation device of all types should be carried out in strict accordance with the project, which in turn should be approved by the fire authorities. Unfortunately, I don’t see your project, so I can assume that the forced ventilation was designed for the premises of the first floor: kitchen, living room, bathroom, toilet. Currently, ventilation works successfully and is completely fine with you.
You have plans to extend the ventilation system in the living rooms of the second floor. I am sure that this is not in the project and it is strictly forbidden to do such things. In accordance with SNiP 41-01-2003 ventilation systems should be arranged so that one group is located within the same fire compartment.
In simple words: to create forced ventilation in the rooms you need to design and install a new system that is not connected with the existing one. You can’t just prolong the ventilation! This will be contrary to fire safety standards. The plan of the second floor shows that all rooms have window structures. As a rule, there are enough windows for normal air exchange and maintaining a comfortable microclimate. If any of the rooms or all rooms are stuffy (as you describe), then it is worth considering the option of installing a split system. In this case, it will be correct, efficient and less costly for finances.
You can install a silencer without coordination with supervisory authorities. However, given the location of the Calibri-500 ventilation unit (on the balcony) and the small diameter of the ventilation ducts, it can be assumed that the installation of a pipe silencer will not have a significant effect on reducing noise in the rooms. But on the balcony, the noise level will decrease significantly.
There is no definite answer regarding the installation of an adapter or a static pressure chamber. For powerful flows, you must definitely set the KSD. In everyday life, in most cases, it is enough to install the adapter. I advise you to buy a grille with adjustable verticals and horizontals. With such a grill, you can adjust the flow direction from the adapter.
