I’m always so confused when I read about heat pumps online. In Australia we’ve had heat pump based air conditioning for like decades as far as I understand. Using them to cool indoor spaces is almost essential given how hot it gets in some parts of Australia. However I’ve never come across such a system that isn’t what we call a reverse cycle aircon, that is, it can also heat an indoor space. We do have evaporative coolers in places that experience dry heat, those cannot work in reverse of course, but they are not heat pumps either.

What confuses me is that, I could understand if this is uniquely an Australian experience to have this in your home, office and shops, but don’t all modern cars have heat pump air conditioners? They usually don’t reverse to heat the inside space, the car instead just dumps the engine’s heat into the interior space and/or uses resistive heating, but still the technology is exactly the same! It’s just missing one component and configuration that makes it reversible.

Maybe I’m way wrong and it’s a completely different thing but idk

Do you guys have… fridges? Freezers?
