Evaluating System Of Energy Saving Of Running Of Central Heating System

The degree of comfort of domestic architecture of our country is not as good as that of developed country. But the energy consumption of domestic architecture of our country is more than that of developed country. For example, the energy consumption of domestic architecture of our country is as three times as that of countries of north of Europe so as Danmark, Finland. To reduce the energy consumption of domestic architecture, many prescripts with regard to energy consumption of domestic architecture is prescribed. Many energy saving buildings were builded in many citis. But the coal consumption of heating in Beijing is 25.3 kologram per square meter according to the inquisition in 2004. The coal consumption is more than the target prescribed by the criterion. So, many expert consider that the energy saving building can't save enery. The reason why the energy consumption of buildings is so excessive is not only the insulating property of buildings, the other reason is that the efficiency of heating system is so poor.To improve the level of running of central heating system, the following content is narrated in this thesis.⑴The facility and the condition which is needed by the central heating system to run in energy saving and the demand in management is narrated.⑵Many evaluating indicators of central heating system is narrated. The expression of operating efficiency is revised and two new indicators are brought forward.⑶The evaluating system of central heating system in running in energy saving is brought forward. The method of application of the evaluating system brought forward in this thesis is illuminated and the practicability of the evaluating system is testified by evaluating the result of running of a central heating system.
