Mini split dual zone question

[Skramy]

As I understand in a mini split inverter system, sensors in the indoor units will make the compressor slow down.
How about a dual zone. There's only one compressor. If one sensor is still calling for cooling, the compressor isn't going to slow down is it?
Pardon my question, but I've been googling for a couple days and still don't understand.

OK, I deleted the comment about efficiency.

It will slow down to a point but two seperate systems will have a higher seer rating and be more efficient than a dual zone system. Two seperate systems also add some redundancy. The down side is another outside unit/disconnect/and slightly higher equipment cost.

Let me be clear we are talking about mini splits. A dual zone mini split in most installs are going to be more efficient than a central hp.

It is magic! FB43 is correct on the cost and efficiency side of multis. If it is going to be run a lot you are better off going singles, if you can spare another 20 amp breaker. My dual in the upstairs of the house is 16.5 seer, but is used only for cooling on occasion. The singles downstairs are 25 & 26 seer and used year round for H&C. The singles will heat down to lower temps as well, but you don't say where you are, so...?
