| It is an important link in building energy saving to household metering for existing residential building’s heating system, and after transformation, the heating system should be both can achieve energy saving and meet the user’s thermal comfort. At present, there are still some deficiencies in the current domestic heating metering methods, such as fairness, operation and social acceptance, which should be further improved. The research of existing residential building’s heating system has broad application prospects. The main content of this paper is to study the transformation of existing residential building heating system, develop the heating metering method that conform to China’s national conditions, at the same time it could achieve building energy efficiency and meet the thermal comfort of users.This paper analysis several basic principles of heating metering methods in China. Describe the advantages, disadvantages and scope of application of these methods. Sum up the common characteristics of heating metering system, propose principles that should be followed in the selection of heating measurement transformation method.Then combine with the existing heat metering technology and according to the characteristics of existing residential buildings, propose two kind of heating measurement transformation scheme that for existing residential buildings in the vertical single pipe system, research the heat distribution principles of these two schemes. Establish the mathematical model of the corresponding heat distribution and derive the formula of the heat allocation, design the corresponding heat allocation scheme in different on-off mode.Based on the two kinds of heat allocation schemes, develop heat metering and monitoring management system, design collection scheme, indoor temperature control scheme, data transmission scheme. Design monitoring software which is matched with monitoring system, used to realize user authentication, data monitoring, remote management. |
