About 25 years back here in Australia they were advertising Fujitsu air-conditioners, they had the promise of some like "They will get the air down to 17c in all conditions."

About a month later there was a summer heat wave and I went to a friends house who had just bought one. It was wild walking in from a 45c day into, as advertised, a 17c house. Had to give it to them, they lived up to the claim.

That they come from the telecom/server space, it makes sense they had a good eye for aircon engineering.
