Vapor compression refrigeration has been mass produced for a century. Add a reversing valve and you have a heat pump. Europe better get started on installs, it’s not going to cool down.

What makes you think that this isn't happening?

China ramps up production & shipping to Europe [1] and a quick glance at Google Trends for Germany, UK and France AC install searches are up 5x from last year, and last year was already double or more of the previous years.

I have a heat pump based water heater installed in the garage. One side benefit is the garage got cooled down. It used to be that the garage got very hot during hot days. Now it’s cool.

I have a warmtepomp -- it's great, but it is cooling the house, not the air a only gets it to 5 day degrees down. It's mandatory for new houses in Amsterdam I think and there seem to plans to retrofit old buildings. It helps that we also produce it, but the usual types tried to sabotage that too last time.
