Application of flow-coefficient distribution method to heat metering for single-pipe system

The cost of household-based heat metering reconstruct is very high for existing single-pipe heating systems in northern part of China. Based on the practical experience for many years, performs simpler reforms of the conformation of original single-pipe heating system. The temperature adjustment of the reformed system under certain conditions has little effects on the flow of the system, so the system can be considered as a constant flow system and can be metered with flow-coefficient distribution method replacing flow metering method. Reform expenditure can be notably saved by using this method.
