A/C is air conditioning. One way. They actually extract heat, not pump cold in.
All mentioned systems are heat pumps.
Systems that can pump in two directions are inverter reversible systems. Many, if not most modern AC systems are inverter reversible heat pumps.
“Aerothermal” in English is called “Air source heat pump”.
A heat pump is called an air source heat pump when the quantity of heat (or cold) moves exceeds the energy expended, so if you get 2 or more units of heat (or cold) per unit of energy, it’s considered “Aerothermal”, because it’s extracting that heat, in either direction, more efficiently than just burning or consuming the energy source, like gas, or electricity.
Many air to air split systems today are “aerothermal”, and are not more expensive than traditional split A/C units. Look for SCOP values higher than 4. Some of the better ones, from top manufacturers like Mitsubishi, Daikin, LG, etc. have better than 5 SCOP. These are often considered renewable equivalent, and in many countries qualify for incentives and rebates.
The phrase air conditioning doesn’t mean, one way. More common understood meaning is just cooling.
However by definition conditioning to air from its existing condition to a more suitable condition is conditioning. No heating or cooling specified.
Japan/Korea aircon means something that can do both. UK, US, other commonwealth. AC means just cooling.
Thanks, that clarified a lot of things for me. I checked the stats on my Panasonic heat pump and for the last 12 months its average COP was ~4.5. So pretty good.
OK, let me geek out for a bit:
