Research And Optimization Of Central Heating System

The main parts and equipments characteristics of central heating system are summarized and introduced. Thermodynamics analysis is done to various heating systems about central heating system, by analyzing the thermal efficiency and the exergy efficiency of central heating system, we get the conclusion that the more energy-saving heating scheme is CHP. Analysed the impact on heating net of the heating pararmeter.Take a case as an example, do the hydraulic calculation and economy analysis of the pipe networks on different heating medium, then get the more accurate data about the trend on heating pipe networks and the temperature difference, then give some suggestion on heating medium. Finally, considering economy, environment protection, energy saving and other indexes, maths model is established to analyze and value the central heating schemes by using theory of grey relation and comprehensive fuzzy evaluation. The optimal scheme is selected from several schemes of central heating system.
