为了减少设备、管道及其附件的散热损失,需要对其采取保温措施。但是保温工程本身也要花费一定的投资,这包括工程的施工费用、保温材料费用以及运行期间的维护费用等。因此,为了使保温结构具有良好的经济性,就必须使保温结构的投资和运行期间的维护费用不超过所节省能源的费用,这就涉及到 In order to reduce the loss of heat from equipment, pipes, and accessories, insulation measures must be taken. However, the thermal insulation project itself also requires a certain amount of investment, which includes construction costs, insulation material costs, and maintenance costs during operation. Therefore, in order to make the heat preservation structure have good economical efficiency, it is necessary to make the investment in the heat preservation structure and the maintenance cost during the operation not exceed the cost of the saved energy. This involves
