Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0024] Considering that the existing methods often do not take into account the specific operation of the indoor unit and the outdoor unit when controlling the operation of the outdoor unit, but mechanically control the operation of certain outdoor units according to the preset outdoor unit combination control scheme . For example, it is fixed to control the operation of No. 1 outdoor unit, No. 3 outdoor unit, and No. 4 outdoor unit in sequence in the first operation cycle; control the operation of No. 2 outdoor unit, No. 3 outdoor unit, and No. The operation of the outdoor unit does not take ...

Abstract

The invention provides an outdoor unit operation control method and device for improving the operation energy efficiency and the stability. The method comprises the following steps: capacity data of an indoor unit operated at present is obtained; multiple matched outdoor unit combinations are determined according to history operation data of outdoor units and indoor units; preset index parametersof the outdoor units in preset time periods are obtained, and the priority of the outdoor unit combinations is determined according to the preset index parameters; and according to the priority of theoutdoor unit combinations, the multiple outdoor unit combinations are operated in turn. The method obtains the capacity data of the indoor unit operated at present and the history operation data of the outdoor units and the indoor units, and accurately determines the matched outdoor unit combinations with high efficiency energy according to the obtained data, so that the operation efficiency energy is improved; and the priority is determined through combination with the health degree of the outdoor units, and the outdoor unit combinations are operated in turn according to the priority, so that the operation stability is improved, and the technical problems of low operation energy efficiency of the outdoor units and weak stability in traditional methods are solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an operation control method and device for an outdoor unit that improves energy efficiency and stability of operation. Background technique [0002] When operating equipment such as air conditioning units, it is often necessary to arrange corresponding indoor units indoors and outdoor units outdoors, and then through the coordinated operation of indoor units and outdoor units, to achieve the overall operation of equipment such as air conditioning units . [0003] Furthermore, for units with relatively large structures or multi-cascaded systems, such as large central air-conditioning units, etc., a plurality of basic outdoor units with different capacities are often arranged outdoors and combined to form an outdoor unit. During specific operation, one or more outdoor units can be selected from the above-mentioned outdoor units for combined operation each time, so as to c...
