Embodiment 1

[0090] refer to figure 1 , the multi-system air-conditioning scheduling method provided in this embodiment includes the following steps:

[0091] Step S101: Obtain the cumulative running time and historical failure times of each air-conditioning system respectively.

[0092] When the multi-air conditioning system is powered on, all the air conditioning systems are not running at this time, and the cumulative running time and historical failure times of each air conditioning system are obtained at this time: when an air conditioning system is running, its running time will be accumulated , if the air-conditioning system fails, the historical failure times of the corresponding air-conditioning system are accumulated, so as to obtain the cumulative running time and historical failure times of each system. Generally speaking, the above-mentioned cumulative running time and historical failure times will be written into the storage device. When the unit needs to obtain the above d...

Embodiment 2

[0130] refer to figure 2 Compared with Embodiment 1, the multi-system air-conditioning scheduling method provided in this embodiment further includes the following steps:

[0131] Step S201: When all the air-conditioning system loads corresponding to the highest starting priority are started, after the air-conditioning system corresponding to the highest starting priority is excluded, the loss coefficients of each of the remaining air-conditioning systems are compared with each other, Re-prioritize the activation of each air conditioning system;

[0132] Step S202: When the system startup conditions are met, start the corresponding air conditioning system according to the re-determined startup priority order.

[0133] At this time, the priority of the air-conditioning system that has been running is locked and will not change, nor will it participate in the priority ranking of the unstarted air-conditioning system, ensuring that the corresponding air-conditioning system can ...

Embodiment 3

[0136] like image 3 As shown, the multi-system air conditioning scheduling method provided in this embodiment, compared with Embodiment 1, further includes the following steps:

[0137] Step S301: When the system shutdown conditions are met, the corresponding air conditioning systems are shut down according to the startup priority order.

[0138] Further, the method also includes:

[0139] Step S302: After the air-conditioning system is shut down according to the starting priority order, respectively acquire the cumulative running time and the number of historical faults of each shut-down air-conditioning system;

[0140] According to the cumulative running time and the number of historical failures, the loss coefficient of each air conditioning system is obtained;

[0141] Determine the starting priority of each air conditioning system according to the loss coefficient;

[0142] When the system start-up conditions are met, the corresponding air-conditioning systems are st...

Abstract

The invention provides a multi-system air conditioner dispatching method and device and an air conditioner, and relates to the technical field of air conditioner systems.The multi-system air conditioner dispatching method is characterized by comprising the following steps that the accumulated running time and the historical fault frequency of each air conditioner system are obtained; the loss coefficient of each air conditioning system is obtained according to the accumulated operation time and the historical fault frequency; determining the starting priority of each air conditioning system according to the loss coefficient; and when the system starting conditions are met, the corresponding air conditioning systems are started according to the starting priority sequence. According to the method, the starting priority of the multi-system air conditioner is obtained by referring to the three parameters of the accumulated operation time, the historical fault frequency and the system fault occurrence possibility of all the different air conditioner systems and combining the corresponding weight coefficients, and the different air conditioner systems are sequentially started according to the priority and the time sequence; and the service life of the multi-system air conditioning unit is prolonged on the premise of ensuring that the unit can be stably and continuously started and operated.

Description

technical field [0001] The invention relates to the technical field of air-conditioning systems, in particular to a multi-system air-conditioning scheduling method, device and air-conditioning. Background technique [0002] A multi-system air conditioner generally consists of an outdoor unit and multiple indoor units. The outdoor unit includes a compressor, an outdoor heat exchanger, and an outdoor electronic expansion valve. Each indoor unit has an indoor heat exchanger. The compressor, the outdoor heat exchanger, the outdoor electronic expansion valve and the indoor heat exchanger are connected to each other to form a refrigeration cycle, so that refrigeration and heating can be performed through the refrigeration cycle. [0003] When the existing multi-system air conditioners are in operation, the on-off, off-off, and operation scheduling of the units are generally realized in the manner of starting and stopping the systems sequentially. [0004] Since there will be a ...
