Evaluation of energy effects of the heat distribution network modernization

The work concerns the estimation of energy effects of modernization of a part of an existing heat distribution main, which is part of a system that supplies heat for heating and domestic hot water preparation. The energy effect was defined as the difference between heat losses in the installation pr...
