Analysis of influencing factors of variable flow rate in a heat metering system;

Employment of flow adjustment formulas in heat metering systems;

As a new type of "commodity" ,the heat metering is entering people\'s lives.

Through the comparative analysis of the acquired data from 2006 to 2007 in a metered heating residential area,the location heat consumption ratio coefficient that reflects the influence of user room locations on their metered heat is calculated.

The metered heating system of residential area in Tianjin is studied.

On the basis of the analysis of heat transfer between heat users with metered heating,taking a residential building as study subject and every heat user as an isothermal unit,heat balance equation group is established,and the average room calculation temperature of different heat users during the heating period is determined.

The some problems encountered in the process of popularizing metering heating charge and the corresponding solutions are discussed.

In this paper the particularities of heat as a product are analysis and according to the codes and standards of metering heating in Europe and Germany and combined with Chinese theories and experiences in metering heating an idea that apportion heat price is proposed and discussed.

The characteristics of metered heat-supply of residential buildings in China are analyzed.

Impact of measuring heating on building energy saving;

Combined with regulation & standard of measuri ng heating in Europe & Germany,it illustrates speciality of heat as a kind of comm odity,discusses theory & experience of measuring heating in China,propounds the idea of sharing heat price,and concludes corresponding suggestion for implementi ng measuring heating.

The automatic control methods of heat source and heatsupply network in measuring heating are expounded, and computer automatic control system is introduced by an example of heatsupply network with indirect connection.

Development of residential heating metering allocation software;
