Embodiment Construction

[0027] A multi-connected air conditioner includes at least one outdoor unit and a plurality of indoor units. Each outdoor unit corresponds to multiple indoor units, and a communication link is established between the outdoor unit and the corresponding indoor unit, so that each indoor unit can communicate with the corresponding outdoor unit. The aforementioned communication link may be a wired communication link or a wireless communication link.

[0028] However, the communication link between the indoor unit and the outdoor unit may be abnormal due to the negligence of the installer during the installation and commissioning stage, and may also be abnormal due to excessive use, damage or looseness of the original parts. Abnormal communication between the indoor unit and the outdoor unit will affect the normal operation of the multi-connected air conditioner.

[0029] In addition, the installation of multi-split air conditioners is usually during the renovation period. That is...

Abstract

The embodiment of the invention provides a VRV(variable refrigerant flow) air conditioner indoor unit online detection method and device and a VRV(variable refrigerant flow) air conditioner, and relates to the technical field of VRV air conditioners. The VRV air conditioner indoor unit online detection method comprises the steps: online number of indoor units communicating with an outdoor unit normally is obtained; and when the online number is smaller than a preset value, the indoor units are controlled to execute corresponding actions according to the communication states of the indoor unitsand the outdoor unit so as to distinguish the indoor units in different communication states with the outdoor unit. Therefore, when the indoor unit abnormally communicating with the outdoor unit occurs, a user can quickly discriminate the offline indoor unit, and related personnel can be reminded in time to maintain the indoor unit.

Description

technical field [0001] The present invention relates to the technical field of multi-connected air conditioners, in particular to an online detection method and device for a multi-connected air conditioner internal unit and a multi-connected air conditioner. Background technique [0002] The air conditioner provides diversified environmental control services for the indoor space through the cooperation of the indoor unit and the outdoor unit. An effective communication link is the prerequisite for ensuring the cooperation between the indoor unit and the outdoor unit. However, the communication between the indoor unit and the outdoor unit may be abnormal due to incorrect installation or long-term use. For example, the communication line is wrongly connected or missed during installation, the communication line is dropped after a long time of use, or the motherboard is damaged. [0003] For multi-connected air conditioners, due to the large number of indoor units, no matter ...
