The definition of a mini split ducted system is a type of air conditioning system that is composed of two main parts: an outdoor unit and an indoor unit. The outdoor unit is responsible for compressing and condensing the refrigerant, while the indoor unit is responsible for distributing the cooled air throughout the space. The two units are connected by refrigerant lines, which allow the refrigerant to travel between the two units. The indoor unit is typically installed in the ceiling or in a wall, and the outdoor unit is usually installed outside the building. Mini split ducted systems are becoming increasingly popular due to their energy efficiency, flexibility, and ease of installation. They are ideal for smaller spaces, as they require minimal ductwork and can be installed quickly and easily. Furthermore, mini split ducted systems are also cost-effective, as they require less energy to operate than traditional air conditioning systems. Additionally, mini split ducted systems are often quieter than traditional air conditioning systems, making them ideal for areas where noise levels are a concern.
