What does the term “ductless mini-splits” refer to in HVAC?

The term “ductless mini-splits” specifically refers to an air conditioning and heating system that operates without the need for ductwork. This system comprises two main components: an indoor unit that distributes conditioned air into the living spaces, and an outdoor unit that houses the compressor and condenser. The absence of ductwork allows for greater flexibility in installation, as each indoor unit can control the temperature of individual zones or rooms, providing personalized comfort.

Additionally, ductless mini-split systems are energy efficient, as they eliminate energy losses associated with ducted systems, where conditioned air can be lost through leaks or insulation issues within the ducts. This zoning capability also makes it easier to heat or cool specific areas of a building without affecting the entire space, which can lead to significant energy savings and enhanced comfort levels. In summary, the characteristic features of ductless mini-splits that include their independent operation and zone control make them a desirable option in modern HVAC systems.
