A ducted mini split diagram is a visual representation of a ducted mini split system. It is a type of air conditioning system that uses a single outdoor unit to provide cooling or heating to multiple indoor units. The outdoor unit contains the compressor, condenser, and expansion valve, while the indoor units contain the evaporator, fan, and other components. The diagram will show how the outdoor and indoor units are connected and how the refrigerant flows through the system. It will also show the various components and their locations, as well as the various controls and settings. The diagram can be used to troubleshoot any issues that may arise with the system, as well as to plan for any future upgrades or repairs. It is an invaluable tool for any homeowner or technician working with a ducted mini split system.
