Setting Up VUT 350 PE EC Recuperator in 130m2 House & 60m2 Attic: Speeds & Anemometer GM816 Usage

Question

VUT 350 PE EC recuperator, house, ground floor 130m2 and about 60m2 attic. Unfortunately, I have no contact with the man who installed recuperation. I have to set everything up myself. Currently, I borrowed a benetech Gm816 anemometer and I run on anemostats measuring m / s values. My 1st...

Well that's an installation error. Badly leveled. Some recuperators are installed with a slope and not horizontally.

Arbiter · Answer

in my opinion, the setting of the anemostats is not super important. Choose experimentally depending on what you want to have in which room. I unscrew the mushrooms in most rooms so that they do not resist,

what you typed in the points was probably the fan speeds on each gear. The air handling unit has two fans: supply and exhaust, usually in the menu you can set how to operate. It's safest to put them evenly. In the menu you can also regulate how many% is supposed to blow on which gear. what the device manufacturer predefines is OK. For today's weather, I recommend 2 gear, cold winter 1, and if someone gets cold in the toilet or in the kitchen, 3 runs for 15 minutes

I have a 2-story building, I do not know, I am just learning this recuperator and, according to my amateur logic, I thought that if the openings were open everywhere, more will go where it is closest, where faster access and everything will go there, and screwing the anemostats will allow me to unfold it air distribution force.

Jan_Werbinski · Answer

Generally speaking, you do not regulate the flow by twisting the valves. Similar cable resistances from the distribution box to the diffusers are designed, and any length differences are compensated by bends.
A separate issue is the balancing of supply and exhaust. You use it 99% of the time in first gear and the noise it makes in the rest is irrelevant. Set yourself, for example, 100 m3, i.e. 30%, and if you have separate voltage regulation on both fans, set them so that the supply and exhaust are balanced. This means that in a tight house, in no wind weather, the foil stuck in the open door opening will hang freely. Obviously, changing temperatures is re-regulating, but you will have a roughly balanced supply and exhaust resistance. Better this than nothing.

Thanks for the advice.
As for these 100m3, it probably has to do with the ventilation area I have. During the weekend I measured and I have 450 m3. For now, I have set:
1 mode from 8.00 am to 4.00 pm and this mode has 20% power, i.e. 70 m3, I'm counting correctly?
2 mode from 4 p.m. to 10 p.m. and this mode has 40% power, i.e. 140 m3
3 mode from 22.00 to 23.30 and this mode has 90% power (it is time for all household members)
and from 23.30 to 8.00 am there is 2 mode

as for balancing the exhaust and supply, I have it set equally.

Jan_Werbinski · Answer

The fact that you are set equally has almost no relation to the balancing of the supply and exhaust, because your setting does not take into account the differences in the supply and exhaust resistance as well as the air intake and exhaust.

And is it not so that I have an inappropriate selection of a recuperator for my cubature?
The name of the recuperator indicates that it is intended for rooms of 350 m3, I have 457 m3. Isn't it better in my case to choose a larger one and run with lower efficiency?

Jan_Werbinski · Answer

I don't think it really matters. For example, I ordered a bigger one due to the fact that they have better company motors and lower energy consumption.

marlowe27 · Answer

And listen, reading the instructions, it is talking about setting the temperature in the recuperator pipes and outside, what temperature should this be set?

Jan_Werbinski · Answer

The temperature is not set. You can read it.
The air intake temperature depends on the conditions outside. Extract air from the room temperature. Air supply and exhaust from the recuperator efficiency, flow balance and ventilation intensity (how many m3 / h)

marlowe27 · Answer

Thanks for explanation.
I have the last question, my recuperator is suspended from the ceiling, has a drainage to the sewage system, and yet the screws and in some other places water drips onto the floor. I tightened the screws, but the water, despite being drained, still finds new places to condense on the floor, is it the fault of improper installation?

Jan_Werbinski · Answer

Leaking and leaking. Or poor insulation and condensation on thermal bridges. I bet on the former.

marlowe27 · Answer

I'm in technical matters, but I think I managed to fix the water leak myself ;)

The recuperator was evenly suspended from the ceiling, at its bottom, on a plate like this, water collected more and more, and these drainage channels are on the side of the plate. It was enough to slightly tighten the recuperator to the ceiling on one side and lower it on the other, so that the water could flow down to one side of the plate (where there are openings to the sewage system).

By the way, producers could make water drainage holes in the bottom of this plate, then the problem would never arise

marlowe27 · Answer

Thank you very much for your help, you have a lot of knowledge about recuperation. And do you know heat pumps too?

Jan_Werbinski · Answer

What knowledge? I haven't even installed my recuperator yet. He is waiting on the table and I am drilling holes.

With heat pumps, I have experience heating with an air conditioner for the ninth winter as the main source of heat and I recommend it to everyone.
