All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
In order to accurately and quickly recommend different air conditioning equipment configurations required by different customers in store marketing, the application provides a professional air conditioning equipment selection and generation method supporting self-definition.

step 1, obtaining scene information and drawing and generating a scene, wherein the scene information comprises house type information, soft-clothing furniture design information and hard-clothing design information.
The embodiment supports scene drawing in two-dimensional space or three-dimensional space, and comprises house type drawing (straight wall, arc wall and the like), soft furniture design (bed, sofa and the like), and hard furniture design (paving, ceramic tile and the like).
For example, the house type information shown in fig. 2 includes a main bed, a guest bed, a study, a toilet, a guest restaurant, a balcony, etc., and is provided with an outdoor unit, a floor outside the balcony, and two indoor units, which are located at the top of the guest restaurant. It should be noted that fig. 2 is a schematic diagram of an interface effect of software operation, which is only used for illustrating the distribution of the house type, and the structural content in the diagram has no limit effect on the scheme of the present application, so the detailed content in the diagram is not detailed.
And 2, generating a 2D house type thumbnail based on the house type information, and adding a mark of an air conditioner internal unit to be generated to a corresponding room in the house type thumbnail according to the user behavior data.

And modifying the unit area cooling load and the modification coefficient of different rooms according to the behavior data of the users after the areas are determined. It is easy to understand that, since the unit area cooling load has a default value according to different areas, if a user has newly input unit area cooling load data for a certain room after selecting an area, the default unit area cooling load is modified, otherwise, no modification is needed. In addition, the correction coefficient can be set to be a default value as the unit area cold load, or can directly receive user input data without setting the default value.
