摘要： To solve the problem that a resonance phenomenon occurs between an outdoor unit and a compressor of existing air conditioners, embodiments include a compressor and a pipeline connected to the compressor. A control method includes obtaining a vibration displacement of the pipeline during the operation of the air conditioner and recording it as a first vibration displacement; obtaining the vibration displacement of the pipeline again after time has elapsed and recording it as a second vibration displacement; and selectively adjusting operating parameters of the compressor according to the first vibration displacement and the second vibration displacement. The vibration condition of the outdoor unit is determined through the real-time vibration condition and the vibration change condition of the pipeline so the air conditioner can selectively change the operating parameters of the compressor according to the vibration condition. Thus the vibration condition of the compressor is changed to avoid pipeline damage.

摘要： An address competition method of a multi-connected type control system. The method aims at solving the problem of how to set an indoor machine communication address in the multi-connected type air conditioner system efficiently. For the purpose, a primary control device (such as an air conditioner outdoor machine) performs broadcasting on each address in a preset address section in sequence. A slave control device (such as the air conditioner indoor machine) responds to the primary control device on the basis of preset responding time and the number of currently broadcasting times of the primary control device. The primary control device to which a communication address is distributed temporarily is responded so as to finish address competition rapidly. Meanwhile, the primary control device can perform continuous broadcasting on one address for repeatedly, so that the competition success rate of the address is increased.

摘要： A method for controlling the balanced frosting of outdoor units in a multi-split air-conditioning system solving the problem in existing multi-split air-conditioning systems of resource waste caused by a low utilization efficiency of the heating capability of outdoor units as a result of some of the outdoor units entering a defrosting state when the heating capability is not fully utilized. According to the control method, by determining whether an outdoor unit set satisfies a frosting unbalance condition, the actual output capability of outdoor units of the outdoor unit set is selectively controlled on the basis of the frosting degrees of all the outdoor units. Thus, the difference between the frosting degrees of different outdoor units in the outdoor unit set at the same time can be reduced, such that the heating capability of all the outdoor units can be fully utilized when the outdoor unit set enters a defrosting state.

摘要： A relay device and a multi-split control system that achieve reliable communication between an outdoor air conditioning unit and multiple indoor units under the condition that the length of a communication bus is limited. The system expands the communication distance by a cascade path formed by a plurality of relay devices. The cascade path transmits control signals sent by a master control device/a specific slave control device (i.e. a slave control device communicating with the master control device or certain relay device) to corresponding slave control devices one by one, and the corresponding slave control devices transmit the signals to the master control device/specific slave control device according to a response signal fed back by the control signal, where the relay devices may respectively communicate with a source node device and a destination node device on the basis of the master-slave type communication mode.
