Had this confusion how the all weather ACs function ,thought more over it and came to the conclusion that we cant make the refrigerant do both the jobs while just by making the refrigerant flow in one direction ,so the only option left is to reverse the direction of flow of refrigerant and now while searching more about the system functioning got the answer that it actually is the thing done in the systems .
But one thing is still confusing about the capacity of the heat exchangers(evaporator and condenser) are they mode of same capacity because it seems more unlikely to have the evaporator of same capacity needed for the condenser of same capacity,or is there any other thing that is done to make the system work for both the cooling and heating???
The coil should match the load profile for the zone it's being installed in. Most of the coil sizing you won't need to worry about as long as you select a unit that will meet the peak demand dictated by your heating and cooling load. The equipment manufacturer publishes performance data on their units, just make sure it will meet your peak demand.
thank you for the valuable explanation.
is there an explanation for the processes that take place inside controller box?
how the simultaniuos operations is going?
We'll cover that in a latter video. Just wanted to cover the basics in this video. Inside the box there are valves that act similar to reversing valves, but keep watching we will cover this topic again. Thanks for watching.

This sounds like it could work well with a geothermal system.
Yes, you're correct, there are VRF Ground Source Heat Pumps. Thanks for watching.
