Document Type and Number:
WIPO Patent Application WO/2021/233475
Kind Code:
A1
Abstract:
The present invention relates to the technical field of air conditioners. Provided are a communication method for indoor and outdoor units of a multi-split air conditioner, and a multi-split air conditioner, which aim to solve the problems of the low communication speed and poor communication quality of indoor and outdoor units of an existing multi-split air conditioner. The multi-split air conditioner comprises an external communication task and an internal task, wherein the internal task at least comprises a zero-level task. The communication method for indoor and outdoor units of a multi-split air conditioner comprises the following steps: S1, determining a communication bit error rate of an indoor unit; S2, comparing the communication bit error rate with a communication bit error rate threshold to obtain a magnitude relationship therebetween; and S3, determining the level of an internal task according to a comparison result, selectively directly executing a first communication policy according to the level of the internal task, or hierarchically splitting a zero-level task into a plurality of subtasks to form a new internal task, and then executing a second communication policy, or directly executing a third communication policy. By means of the communication method for indoor and outdoor units, the level of an internal task is determined, and different communication policies are then selectively executed according to the level, so as to increase the communication speed of the indoor and outdoor units, and improve the communication quality thereof.
