Solar Hot Water Systems Engineering Research And Development Of Computer-aided Design System

Under the nervous circumstance in the resources of world, the solar energy heat makes use of the technical engineering also gets to value. But the personnel who do with engineering design has stronger engineering experience and engineering ability, at same time when engineering designs, he must search a lot of the engineering data. The engineering technique exists the individual difference and the sameness, the individual difference is that one engineering is difference others, it say that: no one engineering is complete with another. But the difference engineering have certainly same, such as : the basic engineering parameter that want to be calculating is same alike. Therefore, engineering personnel when the engineering designs, have the some work is repeated and trivial, the efficiency of engineering design is hard to increase.Compute can do efficiently with lots of data, complete all kinds of data calculation quickly, which can alleviate the personnel's calculation workload very much. The calculator shows its superior in the aspects of handling data. Along with the graph of technical emergence in calculator, it is possible to make use of the calculator to handle the graph, The personnel can utilize time and energy to advance the technical.Because of the extensive usage of the solar energy hot water system, it is urgent to increases work efficiency, but the engineering of the solar energy hot water system, many works is repetition, trivial when design, this make the work efficiency is hard to advance.The calculator aided design of the solar energy hot water system engineering and AutoCAD secondary exploitation system aim to this thing. There is not reported about this task in domestic or outside, so this task is new and initiate in this domain.Along with technical development in calculator and calculator techniques and each course technique are mutually permeating, making use of calculator technique increasing work efficiency become a new characteristics for calculator technique developing. This thesis is under the understand the making use of engineering technique, making use of the VB technique combination with the AutoCAD software develop the usage of the solar energy heat engineering system, including to compute mold piece and paint mold piece. Making use of the VB weaves technique, completing the basic parameter of engineering design, first, according to the customer's request, compute to the total area of the solar board , combine with actualcircumstance of the customer, making sure the actual total area of the solar board, on this foundation, calculating the number of the solar board, water tank capacity, the diameter of pipe and the assistance electricity heats power. All of the theories result can modify according to the actual circumstance. This system according to the demand of engineering design, establish two databases, water pump database and water tank database. The design personnel can search a water pump specification and the size of the water tank according to the actual circumstance. Finally can keep design parameter text. The engineering designs and construction can not get away from the drawing. Because the engineering general usage of AutoCAD software, and its have got the extensive and applied foundation in the domestic, so choose AutoCAD software as the terrace of plot mold piece. Making use of The technique of ActiveX Automation that AutoCAD support, making AutoCAD as a sketch window of VB technology, making use of it, and set painting environment to according to the demand of engineering painting, After entering AutoCAD environment, can use the all of function. Establishing the solar energy engineering paints the menu, including the in common use engineering diagram frame and the arrange of the solar board and in common use engineering diagram. With the help of this system, the design personnel can reduce the labor of repetition, increase efficiency.
