Don’t think I need to summarize this one. This is bad news for everyone.

    as a Canadian, I agree totally. -40 is wayyyy more tolerable than +40. I’ll take Hoth over Tatooine any fucking day of the week

      As someone who whe experienced both-ish, I tend to agree. There is a point where you just get sick when it’s too hot and humid and it’s way worse than being cold. Your system just shuts down and you feel so bad, and if you don’t get away well you die.

      That said, -35° is the coldest I have lived through and without proper clothing it’s not funny being outside! But it beats dying lol.

        Heat pumps work at >100% thermal efficiency.

        Air conditioners dont.

        An air conditioner is a heat pump… That just works in one direction. It uses refrigeration just the same.

        They both rely on creating a thermal gradient between two heat exchangers. And they are both negatively affected by extreme temperature gaps.

        The heat exchanger facing outside with a heat pump must be colder than ambient temperature by a reasonable margin. The opposite goes for an AC. These qualities break down in extreme ranges for typical hardware.

        This also, as expected, reduces the efficiency.
