摘要
在综合考虑原材料购置、设备磨损、电力消耗等相关因素的基础上,提出了采用总投资费用法,运行成本费用法,年计算费用法,费用现值与费用年值法等4种方法对多种换热器投资方案进行分析,便于对不同选型方案进行经济性分析,以达到技术上可行、经济上合理的目标。
The investment project is analyzed for some heat exchangers, synthetically considerated the factors including material purchasing, equipment abrasion and the power consumption and adopted four ways which are total cost of investment, operating cost, annual calculation cost, the present operating cost and annual operating cost. Diffrent projects are economically analyzed so as to be feasible in technology and reasonable in economics.
