Study of the thermal stress of the engine room of a municipal wastewater pumping station

Summary

The results of a study of the thermal stress of the engine room of a municipal wastewater pumping station in the cold period are presented. The main sources of heat and cold and their degree of impact on the thermal stress of the engine room are considered. The results of modeling heat inputs into the engine room from various heat sources located at the different functional levels of the room are presented. The thermal model takes into account the specific features of the technological process of a high-voltage wastewater pumping station, as well as space-planning solutions for the building under consideration in stationary thermal conditions. The calculation was carried out at a constant wastewater temperature assumed equal +25°C. For the first time, it was determined and proved that the machine room of a high-voltage wastewater pumping station can be classified as a room with high thermal stress.
