Functionally yes but the VRF (variable rate flow) which leads to more efficiency gains is a bit more added on top just an inverter valve. Otherwise the heat pumps would be cycling on and off. That’s also why ACs are typically oversized here in the US. Because they turn on one massive load for a little while then turn it off (cycling). With VRF they’re running steady at a variable output over longer periods of time.
