A mini split adaptor is a device that is used to connect two components of a mini split air conditioning system. It is designed to bridge the gap between the outdoor unit and the indoor unit, allowing for the efficient transfer of energy between the two components. The adaptor is typically composed of a copper tube and a set of wires that are used to connect the two units. The copper tube is responsible for transferring the refrigerant from the outdoor unit to the indoor unit, while the wires are used to power the indoor unit. The adaptor also includes a filter that helps to keep the air clean and free of dust and other particles. The mini split adaptor is an essential component of any mini split air conditioning system, as it helps to ensure that the system runs efficiently and effectively.
