  • That’s the common misconception. The lines running between minisplit units are for refrigirant, not air. It’s essentially a fridge without a box, with the room where theyre mounted becoming the box instead.

    You’re right I was wrong about that, sorry lol.

    It doesn’t. It’s just that people who run AC’s usually shut everything closed and then exhale all that co2, which in an ordinary room with just 1 person in takes <1hr to reach noticeable impairment levels. AC or not, ventilation is important.

    You might be right but I am certainly not opening my windows once an hour during winter, if that’s the standard then we’re all screwed by the time we go to bed with the windows closed. I don’t think this problem is significant enough to justify running an Air Conditioner with the windows open…

    You’re probably thinking about carbon monooxide, not carbon dioxide?

    Yes, I am. As that is the only “real” concern I see with AC’s and gas buildup. As I said co2 is just not a big enough issue to justify not getting an AC or letting it run out the window. Regularly airing out should be common sense, but I think once or twice a day is regular enough for the average apartment






  • I don’t understand your statement. I can have the windows closed all day with no AC and not worry about rising co2 levels. Why would it be different with this device running and circulating air? It’s not like it emits co2.

    This looks like a wall mounted monoblock so you would be right but if it’s a split device with an outside unit, it does actually bring in fresh air. This is wrong, split units dont bring in fresh air either. The only setup that consistently brings in outside air is a monoblock with 2 ducts. Either way, I’m pretty sure running an AC with the windows open is never good advice even if you can afford it.

    The only point of concern would be if you have a gas heater for water etc. in your apartment and run a monoblock AC with just one exhaust hose blowing hot air outside while sucking in new air from the inside. In that case, the negative pressure created by the AC can potentially pull gas that would usually go out the chimney into your apartment.





  • I live in central europe but still would never think twice about leaving the house or entering a tram with a knife in my backpack. I think I actually do still have a swiss army knife in there somewhere that I’ve been carrying literally anywhere I go for the last couple years.

    To me it’s a little strange to compare knives, which are primarily tools, to firearms that are from start to finish designed for the sole purpose of killing and injuring living things. My life would be worse without knives, I use them every single day. But I’ve never required a gun for anything
