Air conditioning not only include heat or cold but also humidity.
Thanks,

Hello Jürgen

It looks like that ammo rooms had also a radiator for warming, just like the bathroom .
You can see in the ammo room a large niche for a radiator ??

Maybe the Lufthitzer could also be used for ventilation when they running cold water in the pipes ??

Hello JEF, hello Jos,

Thank you for the “three J´s” discussion.

As I thought, in Norway (Austratt) refrigerating is not necessary.

I did not pay much attention to the (small) radiator in the ammo-magazines even though this fact has been extra mentioned in the french after war report.

Whenever I have been inside the Bunker it was always cool (april, may, june, september) – and rare are the days when the temperature outside is near the freezing point. As the whole Bunker is covered by sand and 3,50 m concrete the temperatures will not change very much.
Within the limits of 15 degrees it is not so difficult to heat or to cool the magazines.
So the idea to use the heat exchanger as cooling device as well is really not bad. The groundwater is really “icy”.
Next time I will mesure both temperatures: inside air and water.

Conclusion (for the moment): no refrigerant compressor necessary for cooling, the radiator plus preheated air will be sufficient for warming

Wim,
I did not see your post before.

As to the influence of humidity of the propellant and its storage I looked into the book “Leitfaden für den Artillerieunterricht in der Kriegsmarine, Teil I: Ballistik, page 21 (1938)”.

Here is written: ............ “Bei vorschriftsmäßiger (constant temperature) Munitionslagerung ist die Änderung des Feuchtigkeitsgehaltes des Pulvers sehr gering. Der Einfluß auf die Vo wird deshalb in der Front vernachlässigt.
JEF knows certainly much more details about.

A major effect of the ventilation of preheated air is the exchange of warm air with higher water content against fresh air (during the night) with less water content, if necessary, thus decreasing a possible increase of humidity inside the building. Like at home !

I can remember reading on this site, some months ago, that I would not have the guts to wet myself in order to measure the basements in Karola.
I am not going to name this guy, not out of respect, but since he is insignificant to me. He was, as very usual, wrong !

Nice picture !

So the hallway with stairs is on the left ? With the amo door way / hatch.
Any change that there is also a picture of the other side of the room ? and the room left of the stairs going down ?
Thanks,
