| In order to solve the problem on huge energy consumption in winter heating in our country, ministry of construction prescribed that household metering heating would be gradually realized since 2000.Traditional single-pipe concurrent-flow heating system cannot satisfy individual heat charging and metering, the user cannot adjust the indoor temperature individually and charge according to heat consumption, this paper puts forward the adoptable type for individual heat charging and metering system-centralized heating system with household metering, and do much research on the maximum unbalance rate between the parallel connection loop. At the same time, this paper analyzes the system composes and the model of unit standpipe heating system and indoor horizontal heating system, and get some conclusions. |
