现有单管采暖系统热计量与室温控制实验研究

简要介绍了新建住宅分户热计量五种方式的特点，阐明了旧有集中供暖系统计量改造的现实性，重点介绍了对垂直单管跨越式系统的理论分析和热计量实验研究情况，以及论述了垂直单管顺流式系统实现室温控制的系统改造方案和实现热计量的方法。实验结果表明，垂直单管顺流式系统改造成单管跨越式系统，并在立管下游跨越管上安装截止阀或锁闭阀，可实现热计量和室温调节的需要。

Experimental Study of Heat-metering and Room Temperature Control of Single Pipe Heating Systemin Existing Houses

Characteristics of five types of heating metering in new buildings were simply introduced. The feasibility wasclarified to retrofit old central heating system in order to meter heating. The oretical analysis and experimental study ofheat-metering of upright single pipe crossover type systems were performed. Methods for retrofitting upright single pipeseries-loop heating system to realise easy room temperature control and heat metering were introduced. It was shown that by retrofitting the upright single pipe series-loop heating system to upright single pipe crossover type system, and installing shutoff valve on the crossover pipe of the downstream of the riser, heating metering and room temperatare control can be realized.
