ERV & HRV Units Explained

Energy Recovery Ventilators & Heat Recovery Ventilators explained – what they are used for and how they work.

Buildings need fresh air for indoor air quality. But introducing fresh air comes with an energy penalty.

This is where ERV & HRV units help.

I like the role reversal in this video - music over and background voice.

Saya kesini setelah lihat komen om joy di chanel sebelah, masih terkait matic...mantep tips2nya, terutama pas nyimak alasan kenapa jangan sering pindah dari D N DN😊

this video's background music isn't loud and annoying enough

[goetzfrank]

Next video please without music. What you think might be uplifting and fun might just be bothering and annoying for the next person. This is about information. Thanks. Good info.

Thanks god captions exist, i had to turn the volume down coz of background music

[phillichillin]

Thanks for this, finally getting my head around it

Great video very informative appreciate your time I live in the Las Vegas area and I'm interested in are exchanging in my home. I had a quick question how well do ervs work in hot extreme hot weather 120° in the summer months. I'm worried about hot air coming in to the home. Are ther e any thing I. Particular I should be considered with before I interest money in to this project ¿

Great video. Really clear explanation. One question: So with the ERV - is there some air exchange or how does the humidity get exchanged? If there is air exchange how to you clean exhaust air before (or after) it mixes, as it will have high co2 and airbourne virus particles etc? With a HEPA filter or similar for virus's? That won't scrub the co2 though will it?

Hi, nice presentation!
How did you calculate 18°C?
21°Cx0, 8=16, 8°C? What am I doing wrong?

[ernestoc]

Could you please turn up the music? I can still hear the narrator

[baijopaul]

Any option to use in Church ? What about the cost factors ?

[TinaWavelet]

When will people learn not to use any background music in educational videos?

[malludxb]

So what is the diffrence compre with FAHU

Does anyone know how to connect this to Ecobee Smart thermostat?

I am in Togo Africa and i need to install units but its very large its around 7152 square meter factory, and if i install this type how do i know the temperature inside the factory with 3ACH(air change per hour around 151000cfm) because i think if i change the air more, then i will arrive to more equal temperature with the outside air.

what do you use in North east where its very cold but also very humid in the summer?

QUESTION: I am designing a house to build in Canada, so heating and cooling are necessary. I know an ERV is code and also good for air/humidity quality and health. If I were to choose a forced air furnace, would that be a completely separate set of duct work than the ERV? That would be a lot of duct work. With installing an ERV, what is the best whole-home cooling option? I'd be happy with hydronic radiant in-floor heating... but I also want whole-home AC and my design is not conducive to mini-split wall mounted heat pumps. So if I do a ducted forced-air heat pump... will that be a separate set of duct work from the ERV?

Can the units run without exchanging heat? I'm form Texas where we have big temperature changes. Can I for example exchange heat during the day when it 95°F(35°C) and just exchange air not heat when it's night and 60°F(15.5°C)?

[nuvo-gqiu]

If I'm in a house and I find a unit how can I tell if it is an HRV or an ERV by looking at it? I looked up the model number but the model comes in both HRV and ERV versions and I couldn't find any labeling that stated one or the other.

How do you do the actual energy calculations according to the temperature difference and volume rate of air?
