| Popis: | The work deals with district heating systems based on cogeneration plants and the use of carbon dioxide heat pumps in them. Heat pumps are used in heating systems of buildings and use the heat of outdoor air as a source of low potential heat and, at the same time, the heat of return network water. The aim of the study is to develop the structure of a heat four-pole (HFP) for fitting of heat pumps with district heating system, determine the parameters of a heat exchanger with a variable surface area of the heat exchange installed in the return water line, and analyze one of the schemes of the HFP. The goal to be sought is achieved by solving the following tasks: development of requirements and justification of the HFP scheme, justification of it’s parameters. The most significant results are developed models of statics and dynamics of heat exchanger in HPF, means of the integration of carbon dioxide heat pumps into heat networks with high temperature schedules. The significance of the results obtained consists in deriving dependencies between the temperature schedule of heating system and HFP parameters, which can be used in the practice of designing a district heating systems with heat pumps. As a result of calculations, equations were obtained for the describing of the relationship between the area of the heat exchanger installed in the return water line, temperature drops at the ends of the heat exchanger, heat power of the heat exchanger. |
