Abstract

The invention relates to a communication fault detecting device and method in an air conditioning system which has an outdoor unit connected with a plurality of indoor units, aiming at making use of the wired/wireless controller to cut off the communication of the indoor units even when the communication lines connecting the outdoor unit and the indoor units are not separated, so that the indoor unit with communication fault can be more quickly and easily found. To achieve the aim, the communication fault detecting method provided by the invention in the air conditioning system which has an outdoor unit connected with a plurality of indoor units includes: whether a communication fault happens to the air conditioning system is judged; when the communication fault occurs, selectively separate the indoor units through the communication lines and then find out the indoor unit with communication fault.

Description

technical field [0001] The present invention relates to an air-conditioning system connecting a plurality of indoor units to one outdoor unit, and in particular to a communication error detection device and method of an air-conditioning system for detecting communication errors between the outdoor unit and the indoor unit. Background technique [0002] Generally, an air conditioner is a device for cooling or heating an indoor space. By circulating a refrigerant between the outdoor unit and the indoor unit, the liquid refrigerant absorbs the surrounding heat when it is vaporized, and then discharges the heat when it is liquefied. Play the role of cooling or heating. [0003] In general air conditioners, one indoor unit is installed on one outdoor unit. However, recently, users are not interested in a multi-system air conditioner in which multiple indoor units with different shapes and capacities are connected to one or more outdoor units. There is an increasing demand to run...
