流量阶跃变化时供暖房间内温度场的数值模拟
Numerical simulation of temperature field in heating rooms with step change in flow rate
摘要：
两位通断式调节是一种计量供热系统控制模式，与欧洲供热系统控制模式不同的是，其温控阀只有启、闭两种状态。用数值模拟方法研究了该调控模式对室内热环境的影响规律。

Abstract：
The on-off control is a control mode in heat metering heating system. Compares with the control mode in Europe, its temperature control valve only has the two states of on and off. Studies the influencing pattern of the control mode on indoor thermal environment with numerical simulation.
