Description

Today district heating is a well-studied part of the energy system, but despite this, low-temperature district heating has not yet received proper development. Since this is one of the key technologies for energy efficient urban heat supply, the relevance of the problem today is extremely high. This article highlights one of the possible solutions to this problem: the use of waste heat from an enterprise in a district heating system using a heat pump.
The article presents a model of a low-temperature district heating system in the Oktyabrsky village of the Ryazan region. A heat pump is used as a boiler unit. A heat pump is a device for transferring heat energy from a source to a consumer, which is advisable to use for individual heat supply. However, within the framework of the development of the idea of 4th generation heat supply systems, modeling and analysis of a district heating system using a heat pump station is being carried out. In this case, its application solves two problems: ensuring proper cooling of circulating water at the enterprise and supplying thermal energy to the entire settlement.
The study focuses on analyzing the heat loss of a district heating system by comparing simulation results at a standard supply temperature and at a temperature typical of the 4th generation heat supply schedule.
Based on the results, the possibilities of using low-temperature systems in a certain climate were assessed, as well as the use of waste heat of the Serebryansky Cement Plant for the needs of the village. On the basis of the created model, the calculation of the heat and hydraulic losses of the low-temperature district heating system was carried out, as well as a comparative analysis in comparison with the standard heat supply system.
