应用概率论方法,计算了不同房间负荷下某时刻风机盘管水系统通断阀的总开启率。采用所有风机盘管开启率的加权平均值计算风机盘管水系统的总开启率,误差小于1%。在给定风机盘管水系统相对供回水压差等参数的条件下,根据某时刻风机盘管水系统相对水量与通断阀总开启率的关系,确定了实际运行中相对水量的变化范围。
Probability theory method was used to calculate the total opening rate of on-off valves of fan-coil water system at different times under different room loads. The total open rate of the fan coil water system is calculated using the weighted average of all fan coil open rates with an error of less than 1%. Given the relative parameters of the fan-coil water system for the supply and return water pressure and other parameters, according to the fan coil water system at a time relative to the total opening and closing of the relationship between the valve to determine the actual operation of the relative volume of water changes .
