Abstract

PROBLEM TO BE SOLVED: To provide a thermal environment simulation device for allowing even a person whose analytic knowledge about a car air conditioner is not sufficient to easily simulate a thermal environment. SOLUTION: A model setting processing part 11 makes the respective elements of an analytic model obtained by modeling a vehicle correspond to the constituting elements of a target vehicle. A model analysis processing part 12 executes thermal simulation by using the analytic model set by the model setting processing part 11. A display processing part 14 discriminately displays a menu display part of the model setting processing part 11 and a menu display part of the model analysis processing part 12. When the menu display part is selected, a function selection processing part 15 selects the function of the model setting processing part 11 or the model analysis processing part 12 to start the corresponding processing. When the setting function of the model setting processing part 11 is selected, a selection control processing part 16 inhibits the selection of the analyzing function of the model analysis processing part 12. When the analyzing function is selected, the selection control processing part 16 inhibits the selection of the setting function in the same way.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermal environment simulation apparatus for simulating a human body and its surrounding thermal environment when developing a product such as an air conditioner.

[0002]

2. Description of the Related Art Conventionally, when analyzing the performance of an air conditioner (car air conditioner) mounted on a vehicle by calculation on a computer, first, an arbitrary analysis model is prepared, and the model is analyzed by numerical simulation. Work is done to predict the indoor thermal environment. As such a numerical simulation technique, “HOND
A R & D Technical Review Vo

0 Air conditioning simulation practical application method 1 ”,“ 221
Practical method 2 of air-conditioning simulation ". According to these reports, the effect of the body structure on the indoor thermal environment may vary depending on the combination of the three elements of heat transfer (convection, radiation, and conduction). For example, simply changing the air conditioning mode However, it has been shown that different non-uniform temperature environments are formed. Therefore, in the analysis work, the body was modeled so that these effects could be predicted, and internal air circulation, external air introduction, solar radiation,
It is necessary to calculate the temperature of the human body, the room temperature, and the like under various conditions such as an air conditioning mode. When an analysis of a car air conditioner is performed by a numerical simulation, generally, all data on a plurality of analysis conditions are managed by a single designer. Further, one analysis operation is treated as a continuous operation.

[0003] In particular, when designing a car air conditioner, analysis conditions determined from members constituting the vehicle body and the size of the vehicle body, analysis conditions determined from the amount of solar radiation to the vehicle, and the like, an air-conditioning mode (a wind outlet There are analysis conditions determined from various items, such as analysis conditions determined from numbers and airflows. Conventionally, under these analysis conditions, one designer repeats individual computer calculations in one analysis operation to obtain a final analysis result. Japanese Patent Application Laid-Open No. 2000-34 discloses a product development support device for analyzing the performance of a car air conditioner by calculation on a computer.
What is described in 8214 gazette is known. This product development support device analyzes an air conditioner based on a lot of data input by a designer. That is, a solid model of a product to be developed is created from the input data, and the product is determined by analyzing the solid model.

[0004]

However, in the performance analysis work of the conventional car air conditioner as described above, all data necessary for the analysis of the air conditioner must be input by the designer himself. There is a problem that a person who cannot input data satisfying the analysis conditions cannot perform the analysis work. That is, as described above, since there are analysis conditions determined from various items, conventionally, it is impossible to analyze the performance of the car air conditioner unless the person has sufficient analysis knowledge of the car air conditioner. is there. This has not been solved by the product development support system described above. For example, in addition to data for creating a solid model of the case part of a car air conditioner, it is necessary to analyze the blower flow rate and heat exchange amount in the case. Is available only to those who can input all the necessary data. Further, for example, when there is an analysis condition that is unlikely to be changed once it is determined, such as a member constituting the vehicle body and the size of the vehicle body, every time analysis work is performed,
There is a problem that re-inputting the analysis conditions causes deterioration of work efficiency. Further, if a plurality of analysis models having the same analysis conditions are prepared every time the analysis operation is performed, there is a problem that computer resources such as a memory required for the analysis operation are wasted.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems. For example, in a work of analyzing the performance of a car air conditioner, even a person who does not have sufficient analysis knowledge of a car air conditioner can easily simulate a thermal environment.

Therefore, the present invention is characterized in that the air conditioner includes an outlet selecting means (for example, step S53 of the embodiment) for selecting an outlet class used in the simulation by designating the air conditioning mode. With the above configuration, the condition of the outlet of the complicated air conditioner is

Is characterized by including a model setting conversion means (for example, step S56 in the embodiment) which treats as a condition of the same or a heat insulating wall as the wall around the outlet when obtaining the temperature distribution in the vehicle interior. With the above configuration, the condition of the air outlet of the air conditioner is set by a simple selecting means, and the thermal environment simulation device automatically or unnecessarily determines whether or not the unnecessary outlet can be calculated as an insulating wall. After the display, the conditions are set as the walls that make up the car body, and the simulation is executed.
