价值工程在高大厂房通风和地暖加热盘管方案选择中的应用

APPLICATION OF VALUE ENGINEERING IN VENTILATION OF HIGH-AND-BIG WORKSHOPS AND SCHEME SELECTION OF FLOOR RADIATION HEATING PIPE-COILS

利用价值工程原理,建立了高大厂房通风方案和地板辐射供暖加热盘管选择方案的评价模型。通过工程实例验证,此模型切实有效。评价结果显示,屋顶通风器对高大厂房全面自然排风效果好,消除余热十分有效;PP C加热盘管的资源和能源使用效率高,可取得最佳的工程效果。

Adopting value engineering,an evaluation model for ventilation scheme of the highandbig workshops,as well as for scheme selection of floor radiation heating pipecoils has been established.Through validation by practical examples of several projects,the results of evaluation show that the roof ventilator has good effectiveness for overall natural draft of highandbig workshops,being very effective for eliminating residual heat;the utilization efficiency of resources and energy for PPC heating pipecoils to be high,hence,optimal engineering result can be obtained.
