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： An address competition method of a multi-connection type control system, intended to solve the problem of how to increase the efficiency of indoor air-conditioner unit address configuration where, according to the order in which a first slave control device initiates an address request, a relay device allocates, in sequence, temporary addresses to all first slave control devices, and according to the temporary addresses, initiates address requests in sequence to a master control device; according to the order in which a second slave control device initiates an address request, the master control device allocates, in sequence, official addresses to all second slave control devices; according to the temporary addresses, the relay device allocates the official addresses to the corresponding first slave control devices. The method can efficiently allocate an address to an indoor air-conditioner unit, and ensures that the address of each indoor air-conditioner unit is unique.
