The whole process is complex and tedious, and a designer often needs to put a great deal of effort to ensure that the simulation process is performed smoothly. This greatly reduces the efficiency of the air conditioner defrost simulation and reduces the design experience for air conditioner designers.

Fig. 3 is a block diagram of an air conditioner defrost simulation system 300 according to an exemplary embodiment of the present invention. The air conditioner defrost simulation system 300 may be implemented, for example, in a computing environment 100 as shown in FIG. 1, or in a computing device 200 as shown in FIG. 2.
As shown in fig. 3, the air conditioner defrosting simulation system 300 includes a model creation unit 302. The model creation unit 302 may be used to create a defrost-based air conditioner three-dimensional surface mesh model. For example, the model creation unit 302 may create a defrost-based air conditioner three-dimensional surface mesh model by importing a complete three-dimensional geometric model (such as a stp-format, igs-format three-dimensional geometric model) provided by an air conditioner designer, or by user input.
In one embodiment, to obtain more accurate simulation results, the model creation unit 302 may examine the initially created defrosting-based air conditioner three-dimensional surface grid model to find a grid whose quality is not satisfactory and adjust it to improve the quality of the defrosting-based air conditioner three-dimensional surface grid model. Whether a grid meets quality requirements may be determined in a variety of ways. For example, a predefined file is stored in memory that specifies a range of various properties (e.g., size, shape, etc.) of the grid. Whether the grid meets the quality requirement can be judged by comparing various attributes of the grid of the defrosting-based air conditioner three-dimensional surface grid model with the specifications of corresponding attributes in the predefined file one by one. For example, if the attribute of a grid is within a specified range of the corresponding attribute of the predefined file, the grid meets the quality requirement; otherwise, the grid does not meet the quality requirements.
In one embodiment, if a quality-unsatisfactory grid is found, the model creation unit 302 may further identify surrounding grids of the quality-unsatisfactory grid and adjust the quality-unsatisfactory grid based on the surrounding grids. According to the invention, this adjustment step may be performed several times until the quality-unsatisfactory grid becomes a quality-satisfactory grid. Grid quality may relate to a number of aspects such as grid size, shape, etc. In one embodiment, the size of the quality-unsatisfactory grid may be adjusted based on the size of the surrounding grid, such that the surrounding grid is symmetrically distributed with the adjusted quality-unsatisfactory grid. In another embodiment, the shape of the quality-undesirable grid may be adjusted based on the shape of the surrounding grid such that the surrounding grid has a matching shape with the adjusted quality-undesirable grid. Those skilled in the art will appreciate that these examples are merely illustrative of the quality of the grid and the invention is not limited thereto.
The model creation unit 302 may be configured to check the data integrity of the defrost-based air conditioner three-dimensional surface mesh model. Methods for data integrity checking are well known and will not be described in detail herein.
The model creation unit 302 may be used to determine whether the defrost-based air conditioner three-dimensional surface mesh model has the same components as the predefined base surface mesh model. According to the invention, for a plurality of different air conditioners, a plurality of corresponding air conditioner three-dimensional surface grid models based on defrosting can exist. In this case, a plurality of corresponding base surface mesh models may be predefined and stored in the memory for a plurality of different air conditioners. In one embodiment, the base surface mesh model that matches the air conditioner designer may be searched from memory based on the three-dimensional geometric model provided by the air conditioner designer. The specific base surface mesh model corresponding to a specific air conditioner defines base information such as the basic components and sub-components (if any) of the specific air conditioner. In one embodiment, the base component may include an instrument panel, an air duct, an interior cabin wall, a front windshield, and the like. According to the invention, the created defrosting-based air conditioner three-dimensional surface grid model must at least contain all the components and sub-components (if any) in the basic surface grid model to ensure the realization of the simulation and the accuracy of the simulation results.
According to the present invention, the model creation unit 302 may determine whether the defrost-based air conditioner three-dimensional surface mesh model has the same components as the predefined base surface mesh model in various ways. In one embodiment, the created defrost-based air conditioner three-dimensional surface mesh model may be represented as information of a part name, a sub-part name, etc., and the base surface mesh model may also be represented as information of a name of a basic part and its sub-part, etc. In this case, determining whether the defrost-based air conditioner three-dimensional surface mesh model has the same components as the predefined base surface mesh model may include: the names of the components in the created defrost-based air-conditioning three-dimensional surface mesh model are compared with the names of the components of the base surface mesh model one by one to determine whether the created defrost-based air-conditioning three-dimensional surface mesh model contains all the names in the base surface mesh model, thereby further determining whether the created defrost-based air-conditioning three-dimensional surface mesh model contains all the components in the base surface mesh model. In particular, if the name of a specific part (or sub-part) of the defrost-based air-conditioning three-dimensional surface mesh model is the same as the name of a specific part (or sub-part) of the base surface mesh model, it is determined that the defrost-based air-conditioning three-dimensional surface mesh model has the specific part (or sub-part) of the base surface mesh model. This example is merely exemplary, and one skilled in the art will appreciate that the created defrost-based air-conditioning three-dimensional surface mesh model and the base surface mesh model may be represented in any other form such that it may be determined in other corresponding ways whether the created defrost-based air-conditioning three-dimensional surface mesh model has the same components as the base surface mesh model. It should be noted that having the same components according to the present invention only means that the defrost-based air conditioner three-dimensional surface mesh model has components covered by the base surface mesh model, and does not mean that the components in the defrost-based air conditioner three-dimensional surface mesh model are identical to the components of the base surface mesh model. For example, both the defrost-based air conditioner three-dimensional surface mesh model and the base surface mesh model have component "air ducts," but the air ducts may have different sizes or different other properties.
In one embodiment, the model creation unit 302 may be configured to generate the defrost-based air-conditioning three-dimensional volume mesh model in response to the defrost-based air-conditioning three-dimensional surface mesh model having at least all components in the base surface mesh model. The defrosting-based air-conditioning three-dimensional surface mesh model having at least all of the components in the base surface mesh model may include that the defrosting-based air-conditioning three-dimensional surface mesh model has exactly the same components (or sub-components) as the base surface mesh model, or that the defrosting-based air-conditioning three-dimensional surface mesh model has more components (or sub-components) than the base surface mesh model. Further, the model creation unit 302 may be configured to recreate the defrost-based air conditioner three-dimensional volume mesh model in response to the defrost-based air conditioner three-dimensional surface mesh model not having any one or more components (or sub-components) of the base surface mesh model.
In one embodiment, after the defrosting-based air conditioner three-dimensional body grid model is generated, the model creation unit 302 may be used to perform quality inspection on the defrosting-based air conditioner three-dimensional body grid model. Similar to the quality inspection of the defrosting-based air conditioner three-dimensional surface grid model, if the existence of the body grids which do not meet the quality requirements is inspected, the body grids around the body grids which do not meet the quality requirements are further identified, and the body grids which do not meet the quality requirements are adjusted based on the surrounding body grids until the body grids meet the quality requirements.
As shown in fig. 3, the air conditioner defrosting simulation system 300 may include a boundary condition setting unit 304.
The boundary condition setting unit 304 may be used to acquire boundary condition setting information through an input device such as a keyboard, a mouse, or the like. The boundary condition setting information may include information for setting components in the defrost-based air conditioner three-dimensional surface mesh model. In one embodiment, setting the component may include setting sub-components of the component, setting properties of the component and sub-components, and so forth.
The boundary condition setting unit 304 may be configured to determine whether the boundary condition setting information conforms to a predefined base boundary condition model corresponding to the base surface mesh model. According to the present invention, a basic boundary condition model corresponding to the above-mentioned basic surface mesh model may be predefined. In the base boundary condition model, the properties and value ranges of the individual components and sub-components (if any) in the base surface mesh model are defined. In this embodiment, the basic surface mesh model and the basic boundary condition model are defined separately, so that the comparison speed can be increased, and the calculation efficiency can be improved. However, in another embodiment, the base surface mesh model and the base boundary condition model may be combined into one model, thereby conserving storage resources. According to the present invention, determining whether the boundary condition setting information conforms to a predefined basic boundary condition model corresponding to the basic surface mesh model may include comparing the acquired boundary condition setting information for each component one by one against the information of each component in the basic boundary condition model. According to the present invention, the boundary condition setting information conforming to the basic boundary condition model may include: the boundary condition setting information just comprises all components in the basic boundary condition model; and the boundary condition setting information conforms to the specifications of all components in the basic boundary condition model. That is, if the obtained boundary condition setting information for each component exactly contains all components in the basic boundary condition model, and the attribute of each component in the boundary condition setting information exactly contains the attribute of that component in the basic boundary condition model, and the values of these attributes are all within the value range of the corresponding attribute of the corresponding component in the basic boundary condition model, it may be determined that the boundary condition setting information conforms to the predefined basic boundary condition model. Conversely, if any of the above is not satisfied, it may be determined that the boundary condition setting information does not conform to the predefined underlying boundary condition model. For example, assume that for a component portal (Inlet), its flow attribute x is specified as 0L/s (liters per second) < x < 500L/s in the base boundary condition model. In this case, if the value of the attribute for the component in the acquired boundary condition setting information is 200L/s, the value of the attribute is considered to be in accordance with the basic boundary condition model. Otherwise, the value of the attribute is considered to be non-conforming to the underlying boundary condition model.
The boundary condition setting unit 304 may be configured to set an air conditioner defrosting calculation model and parameters related to the air conditioner defrosting calculation model in response to the boundary condition setting information conforming to the basic boundary condition model; and otherwise, the boundary condition setting information is re-acquired. The air conditioner defrost calculation model and parameters associated with the air conditioner defrost calculation model may be well known in accordance with the present invention and will not be described in detail herein.
As described above, according to the present invention, there are also the following cases: the boundary condition setting information acquired for each component may also contain more components than all components in the basic boundary condition model, and for the same component, the component in the boundary condition setting information may have more attributes than the component in the basic boundary condition model, and the component in the boundary condition setting information also contained in the basic boundary condition model complies with the specification of the component by the basic boundary condition model. However, this situation may initially be considered as the boundary condition setting information not conforming to the underlying boundary condition model, thereby triggering re-acquisition of boundary condition setting information. This will greatly reduce the computational efficiency of the simulation method and system of the present invention. Accordingly, the present invention distinguishes between such cases where the present invention allows but is deemed not to be in compliance with the underlying boundary condition model and cases where the present invention does not allow and is deemed not to be in compliance with the underlying boundary condition model (i.e., the boundary condition setting information acquired for each component does not contain any one or more components in the underlying boundary condition model, or any component in the boundary condition setting information does not have any one or more attributes of that component in the underlying boundary condition model, or any attribute of any component in the boundary condition setting information is not within the range of that attribute of that component in the underlying boundary condition model). In particular, the boundary condition setting unit 304 may be configured to generate a warning box to indicate non-conforming content in response to the boundary condition setting information not conforming to the underlying boundary condition model. If the non-conforming content indicates that the above-described invention permits, but is deemed to be a non-conforming condition to the underlying boundary condition model, then the air conditioner defrost calculation model and parameters associated with the air conditioner defrost calculation model may be automatically set in response to the user accepting the non-conforming content via input. If the non-conforming content indicates that the above-described invention is not permitted and is considered to be a non-conforming situation to the underlying boundary condition model, the non-conforming content may be rejected by the user through input or boundary condition setting information may be automatically reacquired.
As shown in fig. 3, the air conditioner defrosting simulation system 300 may include a calculation unit 306 for performing calculations based on the generated defrosting-based air conditioner three-dimensional grid model and the set air conditioner defrosting calculation model and its related parameters so as to obtain results related to air conditioner defrosting. In one embodiment, during the calculation, the calculation unit 306 may check the convergence of the air conditioner defrosting calculation. If the calculation converges, the calculation unit 306 may generate an air conditioner defrost report. According to the invention, the three-dimensional surface grid model of the air conditioner based on defrosting can be further improved based on the air conditioner defrosting report so as to finally generate the air conditioner with good performance. If the calculation does not converge, the calculation unit 306 may pop up a warning box to indicate a situation or cause of the calculation does not converge and send an instruction to reset the air conditioner defrosting calculation model and parameters related to the air conditioner defrosting calculation model to the boundary condition setting unit 304 so that the boundary condition setting unit 304 executes the instruction.
Fig. 4 is a flowchart of an air conditioner defrost simulation method 400 according to an exemplary embodiment of the present invention. The method 400 includes, at step 402, creating a defrost-based air conditioner three-dimensional surface mesh model. Next, the method 400 proceeds to step 404 where it is determined whether the defrost-based air conditioner three-dimensional surface mesh model has the same components as the predefined base surface mesh model. If at step 404 it is determined that the defrost-based air conditioner three-dimensional surface mesh model has at least the same components as the predefined base surface mesh model, the method 400 proceeds to step 406 where a defrost-based air conditioner three-dimensional body mesh model is generated. If at step 404 it is determined that the defrost-based air conditioner three-dimensional surface mesh model does not have at least one of the components with the predefined base surface mesh model, the method 400 returns to step 402. In one embodiment, determining whether the defrost-based air conditioner three-dimensional surface mesh model has the same components as a predefined base surface mesh model comprises: if the name of the specific part of the defrosting-based air-conditioning three-dimensional surface mesh model is the same as the name of the specific part of the basic surface mesh model, determining that the defrosting-based air-conditioning three-dimensional surface mesh model has the specific part of the basic surface mesh model.
In one embodiment according to the present invention, the method 400 may further comprise the step of, prior to step 404: and checking whether the air conditioner three-dimensional surface grid model based on defrosting meets the quality requirement. If the grid which does not meet the quality requirement exists in the defrosting-based air conditioner three-dimensional surface grid model, the grid which does not meet the quality requirement is adjusted based on grids around the grid which does not meet the quality requirement. The adjusting step may be performed a plurality of times until the adjusted non-quality-compliant grid meets quality requirements.
In one embodiment according to the present invention, the method 400 may further comprise the step of, prior to step 404: and checking the data integrity of the air conditioner three-dimensional surface grid model based on defrosting.
In one embodiment according to the present invention, after step 406, the method 400 may further comprise the steps of: and checking whether the air conditioner three-dimensional grid model based on defrosting meets the quality requirement. And if the air conditioner three-dimensional body grid model based on defrosting is checked to have the body grids which do not meet the quality requirements, adjusting the body grids which do not meet the quality requirements based on the body grids around the body grids which do not meet the quality requirements. The adjusting step may be performed a plurality of times until the adjusted non-quality-compliant volumetric mesh meets quality requirements.
Returning to FIG. 4, after step 406, the method 400 proceeds to step 408 where boundary condition setting information is obtained. Next, the method 400 may include a step 410 of determining whether the boundary condition setting information conforms to a predefined base boundary condition model corresponding to the base surface mesh model. If, in step 410, it is determined that the boundary condition setting information meets the base boundary condition model, the method 400 proceeds to step 412 where an air conditioner defrost calculation model and parameters associated with the air conditioner defrost calculation model are set. In one embodiment, the boundary condition setting information conforms to the base boundary condition model comprising: the boundary condition setting information exactly comprises all components of the basic boundary condition model; and the boundary condition setting information conforms to the specifications of all components in the basic boundary condition model.
If, in step 410, it is determined that the boundary condition setting information does not conform to the underlying boundary condition model, the method 400 proceeds to step 416 to generate a warning box to indicate non-conforming content. If the user accepts the non-conforming content via input, the method 400 proceeds to step 412 where the air conditioner defrost calculation model and parameters associated with the air conditioner defrost calculation model continue to be set. If the user rejects the non-conforming content by input, the method 400 proceeds to step 408 to retrieve boundary condition setting information. In accordance with the present invention, it may be determined in other ways whether to accept the non-conforming content. In one embodiment, if the non-conforming content indicates that the above-described invention permits but is deemed to be a non-conforming condition of the base boundary condition model, the non-conforming content is accepted and the air conditioner defrost calculation model and parameters associated with the air conditioner defrost calculation model are continued to be set. If the non-conforming content indicates that the above-described present invention is not permitted and is considered to be a case of non-conforming to the basic boundary condition model, the non-conforming content is rejected, and boundary condition setting information is retrieved. Furthermore, in one embodiment, the method 400 may also omit step 416 and subsequent steps, and instead, the step of re-acquiring boundary condition setting information may be performed directly after determining that the boundary condition setting information does not conform to the underlying boundary condition model.
Returning to fig. 4, after step 412, the method 400 proceeds to step 414 where calculations are performed based on the generated defrost-based air conditioner three-dimensional grid model and the set air conditioner defrost calculation model and its associated parameters to obtain air conditioner defrost-related results. In one embodiment, the method 400 may end. In another embodiment, the method 400 may return to step 408 after step 414 to obtain different boundary condition setting information, determine whether the different boundary condition setting information meets a predefined basic boundary condition model corresponding to the basic surface mesh model in step 410, reset the calculation model and parameters in step 412, and perform calculations again in step 414 based on the generated defrost-based air conditioner three-dimensional body mesh model and the set air conditioner defrost calculation model and its related parameters to obtain air conditioner defrost-related results. The steps 408, 410, 412, 414, 416 are repeated so many times. And comprehensively analyzing the multiple generated defrosting simulation results of the air conditioner, thereby obtaining more accurate simulation results.
In one embodiment, after step 414, the method 400 may include the steps of: the defrost-based air conditioner three-dimensional surface mesh model is adjusted based on results related to air conditioner defrost. I.e. returning to step 402, a three-dimensional surface mesh model is created based on the new mathematical model. The method 400 is repeatedly executed in this way, and finally, a mathematical model meeting the defrosting requirement of the air conditioner is obtained, so that the excellent air conditioner is generated.
The air conditioner defrost simulation method 400 according to an embodiment of the present invention is merely exemplary. It will be appreciated by those of ordinary skill in the art that although method 400 is illustrated sequentially, some steps in method 400 may be performed in parallel, combined into one step, or further divided into multiple sub-steps.
