基于CAD-VBA的供暖热负荷延续时间图绘制软件的编制

Development of Software for Drawing Heating Thermal Load Continuation Time Diagram Based on CAD-VBA

根据无因次综合公式法或用户提供的热负荷延续时间两种方式,利用CAD-VBA二次开发程序,通过分别编制热负荷延续时间参数计算、横纵轴绘制和曲线绘制3个子程序,实现了热负荷延续时间图的自动绘制功能,大大简化了工程设计和研究人员的绘制工作,同时避免了人工绘制可能产生的疏忽错误问题。

In this paper, according to the dimensionless synthesis formula method or the duration of the heat load which users provide,by using CAD-VBA secondary development program, the automatic drawing function of the thermal load continuation time graph is realized by three subroutine, including the calculation of the thermal load continuation time parameter, the drawing of transverse longitudinal axis and the drawing of curve. This program greatly simplifies the work of the engineering designer and the researcher, while avoids the inadvertent error caused by manual drawing.
