摘要
Pre-insulated pipes play an important role in the energy-saving heat transport. The paper presents preliminary results of the analysis of heat losses in a pre-insulated triple pipe. The determined heat losses in the pre-insulated triple pipes were compared with the existing pre-insulated overhead network consisting of three separate single pre-insulated pipes in a meat processing plant located in north-eastern Poland, as an example of industrial plants with specific water needs for technological processes. The solution of the triple pre-insulated network was also compared with the network system built of a twin pipe preinsulated pipe and a single pre-insulated pipe. Heat losses in a pre-insulated triple pipe turned out to be about 42% smaller than the heat losses of three pre-insulated single pipes. All calculations were made using a proprietary calculation program developed in Fortran. © 2020, European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ).
