DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for calculating the cost of an air conditioner, and more particularly to a method and apparatus for calculating the cost of an air conditioner which is suitable for obtaining an approximate cost for installing an air conditioner.

[0002]

2. Description of the Related Art Air conditioners installed in buildings and the like are:
Generally, construction is performed in parallel with the construction of the building. The cost of installing an air conditioner is often included in a part of the construction cost of a building or the like, and it is necessary to estimate the cost of the air conditioner before the start of construction of the building or the like. Estimation of the cost of this air-conditioning equipment
This is performed by the method shown in FIG.

That is, when estimating the cost of an air conditioner, first, the heat load of the air conditioner is calculated in consideration of the heat generated when the building such as a building is operated (FIG. 2).
(A) S10). In the conventional heat load calculation method, an architectural drawing (design drawing) 10 is received from a customer or a design office, as shown in FIG. Then, the scale and the volume of the room are calculated by applying the scale to the architectural drawing 10, and the heat transfer coefficient and the like are obtained from the wall structure by a design handbook.
In addition, based on the purpose of the room (for example, whether it is an office or a restaurant), the lighting, the number of people in the room,
The calorific value of the room is determined manually by using a design handbook in consideration of the electric devices installed in the room. Further, a commercially available heat load calculation software (heat load calculation software) 1
4 is started, and the heat load calculation is performed by inputting the size of the room, the heat transmission rate, the calorific value, and the like to the computer 12 to prepare a heat load calculation report.

Next, an air conditioning system is designed by considering an air conditioning system suitable for the building (S11), and an equipment table for realizing the air conditioning system is created (S1).
2). In addition, a system diagram and a route diagram showing routing (arrangement) of hot water pipes, cold water pipes, duct pipes, and the like are created (S
13). Conventionally, when designing the air conditioning system, creating the equipment table, the system diagram, and the route diagram, various CAD diagrams 16 are created using the personal computer 12, and the equipment catalog 18 is used to check and confirm the performance of the equipment. And ask the maker to create the drawing 20, refer to the maker catalog, refer to various technical materials, and make inquiries to the maker by facsimile or telephone to obtain the design calculation document 22. Put together.

[0005] After that, the cost is calculated based on the type and quantity of the components required for the air conditioning equipment, the amount, the price, etc., and an estimate is prepared (S14). In the conventional estimation and preparation of quotes, pipes and duct members were picked up from various CAD diagrams such as route diagrams, their types and numbers were summarized in a tabulation table 24, and a quote 26 was obtained from the manufacturer. Thereafter, the calculation is performed by the personal computer 12 using commercially available spreadsheet software 28.

Further, a running cost required for operating the air conditioning equipment is determined as needed (S15). Conventionally, when calculating the running cost, software for calculating the equivalent operating time method 32 or a commercially available running cost after examining the fuel consumption of the equipment from a handbook or a catalog, and determining the energy cost for each region. (Software) using the personal computer 12.

Hard to see. Also, even when using PC software,
A lot of software must be used, and for example, it is necessary to duplicately input the type, number, and dimension data of members twice or three times. Further, since the same table is created many times, omission of entry of a member or erroneous writing of a quantity is liable to occur, which requires a lot of time for collation and a heavy mental burden on an operator.

Further, in the above-described conventional cost calculation method, since the operator turns over the design handbook and obtains a numerical value or the like which is the basis of the heat load calculation, even if the same condition is used, a different numerical value differs for each operator. May be used, and the accuracy of the estimation is not constant. In addition, if there is no time limit and there is not enough time to investigate, there is a case where a similar estimate in the past may be referred to a numerical value, and a constant estimate cannot be made.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and has as its object to make it possible to estimate the cost of air conditioning equipment easily and quickly.
