| The thesis aims at a muliti layer residence project of in Jinan Baihua small region .According to the heating system of the separating doors in this building controlled by heat meter measurement, it studies the feasibility of the various abstracted cosfficient of the communal heating load calculation .Also it studies the difference from the practice. According it,we can draw conculution that the communal heating load calculation are abstracted and allocated averagely according area and added to thevariable heating load calculation, taking for the charging heating load calculation.The thesis introduces the charging method of household heat-metering and academic calculating formulas of all the abstracted coefficient of the communal heating load calculation from the total heating load calculation in household heat-metering and charging in multiplayer buildings. By using the academic calculating formulas of each factors, we can analyze and calculate the No.23# residence building of abstracted coefficient that is measured by ledge in Baihua small region .Finding the abrration between practicable heat test and theory calculation, sequentially the communal heating load calculation is abstracted from the total heating load calculation of the building.The thesis adopted the effective heat transfer coefficient to heating load calculation,through it,we discover that :the heat consumption of the lowest story door, highest story door and the door stick to gable wall is more than the center door of the building,further approved the necessity that the communal heating load calculation are abstracted and allocated averagely.The study of the thesis is an important component of heat-metering and charging.The result of research settle a steady foundation to successfully developheat-metering and charging of heating general company, at the same time provide academic gists to establish accurate, justly and reasonable heating-metering and charging system and enact correlative laws in future.
