Healthy indoor climate at a minimum of 24° C?

Yesterday outside: 36 degrees...inside 22 to 23. In the bedroom constantly 20

Oh God, my wife would be pulling out the winter pajamas again... nobody wants that... I much prefer a hint of nothing. Long live VS, long live summer!

Without air conditioning, it's nearly 26 degrees here. But I admit, I'm already wondering whether we should have prepared air conditioning for the bedrooms.

However, I wouldn't want it cooler than 24-25 degrees with these outside temperatures. The temperature difference to the outside is too great and one cold after another comes along. It always annoys me when I'm traveling in South China or Hong Kong. Outside 35 degrees, inside 20... Brr....

And exactly here I thought to myself: Why not combine the ventilation system with the air conditioning? Then it would be house-related. So air conditioning somewhere behind the intake to cool the air and then straight into the house : )

A ventilation system with a geothermal exchanger can only cool to a limited extent according to my current knowledge. Is the air volume the problem (not enough cool air?), or is it because the temperature of the outgoing air is too high?

I am currently informing myself about cooling as well. We will probably get a Vaillant recovair ventilation system and a Vaillant gas heating system. I do not have more information at the moment.

Well, you’re not the first to think of that; the question keeps popping up from time to time.

The controlled residential ventilation system is simply not designed to provide the necessary air volumes to achieve a noticeable cooling of the room air. It’s just not intended for that. What these systems were developed for—namely exchanging stale air for fresh air—they accomplish with ease.

Ergo, you would need huge fans and large air ducts throughout the entire house to implement that plan.

That’s why nighttime cooling through controlled residential ventilation works more poorly than well.

Keep our house at 23 degrees with shading and passive cooling via brine water heat pump. The cooling runs almost continuously... but also consumes almost nothing...

I had the air conditioning prepared, but I will not install it afterwards because I actually don't like those things and 23 degrees is absolutely enough for me.

Here, without air conditioning, barely 26 degrees. But I admit, I’m already wondering whether we should have prepared an air conditioner for the bedrooms.

I wouldn’t want it cooler than 24-25 degrees at those outside temperatures either. The temperature difference to the outside is too great, and one cold follows another. It always gets on my nerves when I’m traveling in South China or Hong Kong. Outside 35 degrees, inside 20... brr....

Talk to a doctor. An air conditioner doesn’t make you sick. Viruses and bacteria make you sick. This is a typical silly popular belief and comes from this: In office buildings, etc., there are often central air conditioning systems that move large amounts of air, sometimes from room to room, and viruses and bacteria then spread quite well there. At home, with one indoor unit per room, that doesn’t happen. Air conditioning in cars and airplanes can also contribute to nicely distributing viruses and bacteria in the space. But for that, there must always be a sick person present. If everyone at home is healthy, you can set the air conditioner to 18 degrees and no one will get sick..

The practice says otherwise. Sleep one night with [Klima] and you are dead sick the next morning.
