分户计量住宅采暖户内系统形式对比分析

分户计量住宅采暖技术规程一般推荐:双管放射式系统、双管并联式系统、水平串联单管跨越式系统3种方案。在工程实际项目中,一种新的双管放射式与水平串联单管跨越式相结合的系统得到越来越广泛的应用。针对4种设计方案,结合工程实例,从散热器片数、管长和管径等方面对各系统作了计算对比,说明了4种方案的等效性。

Analysis of Household -based Heat Metering System

Three household system forms are recommended in design technology specification for household-based heat metering in different regions: two-pipe radiation household system,two-pipe household system,one-pipe loop circuit household system.In practice,there are more and more application in combination with two-pipe radiation and one-pipe loop circuit household system among the three forms.Some calculation and analysis are carried out in the areas of radiator's number,pipe's length and diameter for the four systems.It is verified that the four household systems are equal essentially.
