笔者有幸读了不少有关保温层经济厚度确定方法的文章,发现都存在一个不合理的问题,如图1。曲线A是年热损失的燃料费用同保温层厚度的关系曲线.曲线B是保温设施投资费用同保温层厚度的关系曲线.
The author had the privilege of reading many articles on the method of determining the economic thickness of the insulation layer and found that there was an unreasonable problem, as shown in Figure 1. Curve A is the relationship between the annual heat loss of the fuel cost and the thickness of the insulation layer. Curve B is the relationship between the investment cost of the insulation facility and the thickness of the insulation layer.
