Due to the inaccurate judgment of the fault point of the air conditioner in this traditional maintenance method, the efficiency of air conditioner maintenance is low. In addition, for the inverter air conditioner, because there are many protections and some installation locations are inconvenient to disassemble for inspection and measure the fault point, it is more important It is difficult to determine the exact location of the air conditioner failure, which increases the difficulty of repairing the air conditioner failure, prolongs the maintenance time, and affects the use of customers. the
空调***在长时间的运行过程中难以避免的会出现一些***故障，及时地对故障进行排除能有效确保用户的最大使用利益。 It is inevitable that some system failures will occur during the long-term operation of the air-conditioning system, and timely troubleshooting can effectively ensure the maximum benefit of users. the
