Relationship between Relative Humidity and Temperature

If you over-ventilate a building in winter, you can end up with uncomfortably low indoor relative humidity. If you have cold surfaces in your home or holes in your vapour control layer, you can end up with mould and condensation. This video explains how these phenomena occur providing a basic introduction to the key principles of psychrometrics or the relationship between relative humidity and temperature.

Tomas is amazing and we need more people like him in our industry

Thanks Duncan. We really appreciate your kind words and if you could please share our channel and spread the word that would be great.

Absolute magic!, had to smile with all the jugs... here's one I prepared earlier!

Thank you, helping me dial in my cigar humidor!

Tomás: you’re a great “explainer” (In French we would say “vulgarisateur” it could also mean popularizer in English). Please keep on with the good work!

My left ear liked this. 10/10.

Excellent demonstration that really helps you visualise the relationship perfectly! Thank you for doing this.

[@mariannelopezhenthorn]

Great explanation, thank you!

love from india.

Excellent

Brilliant Explanation

03:30 It's more accurate to say local temperature and air composition fluctuations will cause an average 80% humidity volume to sporadically form liquid water droplets from condensation. Microorganisms such as mold spores require liquid water to grow.

it was very helpful and simple quit a lot

[@debstar2005]

Good example, take away management of heating,ventilation and vapour barriers are important to combat low surface temperatures 👏🏾

[@petervd.berghe224]

Well done

[@darrenjamrock2677]

Top lad!

[@racquelsabesaje4562]

and if it is hot temperature the result dry and liquid dries

[@DarpaSeven]

left ear : huh?

[@racquelsabesaje4562]

low temperature cold high temperature hot

[@drak_darippa]

oh man please put this on mono.. playing in only one ear is suuuper jarring

[@racquelsabesaje4562]

humid dry

[@racquelsabesaje4562]

whatever the volume of water it depends upon
