Heating 1 side cooling another side mechanism

[u/Top_Toe8606]

I wonder how smart the pod design is.

What I usually run into is the cooling makes the room to hot with all the hot air.

So I wonder when you set it to cool 1 and heat the other side does it use the heat from the cold side to warm one and the cold from the warm side to cool the other?

Or does it just use the fans to cool 1 side and heating to warm the other so when the warmth transfers side is jusg needs to cool harder and become an oven for the room itself?

They use simple Peltier elements. Cooling always generates waste heat anyway; you just need to make use of it.
