Problems solved by technology

For example, a building or a residence is basically powered by a transformer, which makes the multi-connection system may contain multiple refrigerant systems, and a refrigerant system generally consists of multiple multi-connection outdoor units and indoor units. The external unit of a refrigerant system establishes communication with all the internal units in the system, which brings troubles to installation and commissioning

Abstract

The invention discloses a connection method of indoor units and outdoor units of a multi-split air-conditioning system through power line carrier communication. The multi-split air-conditioning system comprises a plurality of refrigerant systems, and the indoor unit and the outdoor unit of each refrigerant system are connected through power lines. The connection method of the indoor units and the outdoor units of the multi-split air-conditioning system includes the following steps: S1, the outdoor units of each refrigerant system acquire first refrigerant system parameters set inside and second refrigerant system parameters set in each indoor unit of the corresponding refrigerant system; S2, the outdoor units search the second refrigerant system parameters matched with the outdoor units according to the first refrigerant system parameters to establish connection with the corresponding indoor units in the refrigerant systems. The connection method can quickly achieve communication connection of the indoor units and the outdoor units of the same refrigerant system so that installation and debugging are simple and reliable. The invention further discloses the multi-split air-conditioning system.

Description

technical field [0001] The invention relates to the field of multi-connection technology, in particular to a method for establishing connection between internal and external machines in a multi-connection system through power line carrier communication and a multi-connection system. Background technique [0002] In the related art, in a multi-connected system using the power line carrier communication technology, multiple refrigerant systems may exist at the same time. For example, a building or a residence is basically powered by a transformer, which makes the multi-connection system may contain multiple refrigerant systems, and a refrigerant system generally consists of multiple multi-connection outdoor units and indoor units. The external unit of a refrigerant system establishes communication with all the internal units in the system, which brings troubles to installation and commissioning. Contents of the invention [0003] The present invention aims to solve one of t...
