| The paper aims at the heating system of the NO.11# storey in Minxin garden of Xuzhou.In order to satisfy the cent-door measurement, it is time for system to carry out the technological transformation. Therefore, the heat-metering test was carried out in 2004. According as the text figure, made a study of the heat-metering charge.The paper introduces the reconstructive principle of the existing heating system. Also it ascertains the economic and feasible upgrading option through the comprehensive comparison, In the meanwhile, the reduction from the heat dissipating capacity of the heat exchanger could be appeared in the course of reconstruction, which has been audit calculated. The scheme can be satisfied with the cent-door measurement by experimental evidence. Gong without saying, the heating temperature can reach the design requirement.According as the estimative outcome of trial construction, further demonstrated 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, and illustrated that the necessity to amend it. On the base of the experimental result, confirmed the integrated compensative coefficient to every one who dwell at the NO.11# storey in Minxin garden of Xuzhou, rendered the cost of being agreed with the equally comfortable condition and the same room. It has been found that the analysis is equivalently in reason.The textual investigation is an important component of the heat-metering charge. The findings settle a steady foundation to smoothly develop the former systemic reconstruction and the heat-metering charge of Xuzhou, at same time provide academic gist to establish accurate, justly and reasonable heat-metering charge system and enact correlative laws in future.
