Can you get a split AC with two indoor units?
Yes, you can get a split AC with two indoor units. Operating two indoor units allows you to split your system’s cooling capacity between multiple rooms.
One of the downsides of using a split AC system is that the cooling is localized to the area around your indoor unit. That can be a pain if you have a powerful system that makes one room very cold but leaves the rest of your home uncomfortably warm.
The solution to this problem is to connect your split AC to more than one indoor unit to split its cooling power between different spaces. You can do this through a PIBCV (pressure-independent balancing cum control valve) at the outlet of each indoor unit.
You should be aware that splitting your AC like this will not increase its total capacity. At most, your total indoor unit capacity can match the capacity of your outdoor unit.
That’s because air conditioning works likey a conveyer belt of heat. You can’t absorb more heat from your indoor spaces than you can effectively release outdoors.
So the only way to increase the capacity of your split AC is to upgrade your outdoor unit.
