Version of the Solution of the Problem of Optimization of Thickness of the Heat-Insulation Layer in Heat Supply
Statement of the problem. With an increase in the thickness of isolation costs of a construction and operation of the heat-insulated pipeline increase as well. At the same time heat losses, and thus annual costs of the lost warmth decrease. The solution of a task comes down to the minimization of the function of expenses of a working option. Results. In the paper the optimum thickness of thermal isolation of a water heating system taking into account the criterion of the minimum value of the specific given expenses with use of the known algorithm is determined. As the problem of optimization depends on a large number of variables, it is expedient to solve it using software. Conclusions. One of the options for calculating the optimum thickness of thermal isolation on the computer by means of the program for the work with the spreadsheets Microsoft Excel including VBA macroprogramming language is offered. The results received during the work with the program can be used for further engineering calculations.
