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

    As a finn, I can live with -40 °C winters, let them come. At least the invading russians will drop dead like flies in the winter. Again.

      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

          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.
