With the premise of full consideration to heating quality and economic operation, it is necessary to use the method of dividing stage of stage mass regulating, as well as some suggestions to the specific application of the method are provided.

Under the worst conditions,the mix ratio of fresh air and the exhausted,and heat supply quantity are calculated out.

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.
