The answer to 'how does mini split work' is a mini-split air conditioning system, also known as a ductless HVAC system, is a type of air conditioning unit that does not require ductwork to distribute cooled or heated air throughout a home. Instead, it uses an outdoor compressor/condenser unit connected to one or more indoor air-handling units via refrigerant lines. The indoor units are typically mounted high on a wall and are used to cool or heat individual rooms or zones.
Mini-split systems work by using a refrigerant to absorb heat from the indoor air and transfer it to the outdoor unit, where it is then released. This process can also be reversed to provide heating by absorbing heat from the outdoor air and transferring it indoors. The indoor units have fans that circulate the conditioned air throughout the space, allowing for precise temperature control in each zone.
