摘要
无流量计热量计量是一种新型的计量方法,它避免了有流量计热量计量在供暖水水质较差的情况下易坏并丧失准确性这一缺点;该计量方法只需测量温度,就能估算出流量并计算出热量;但是该方法需要测量室内空气温度,给测量带来了麻烦;因此,利用FLUENT软件建立了散热器房间模型,用有限体积方法求出散热器房间平均温度,拟合出了散热器房间平均温度、散热器入口温度和散热器流量之间存在的函数关系;将该函数关系带入到无流量计热量计量模型中,并通过仿真实验验证了结果的正确性,从而简化了该模型。
Heat meter without flow meter is a new kind of measurement.It avoids the perishable and inaccuracy of a heat flow meter which is used when the quality of heat-conveying water is poor.Through the method,the value of heat can be estimated and calculated simply by measuring the temperature.However,the method of heat meter without flow meter must measure the temperature of indoor air,which makes trouble of measurement.Therefore,a radiator room model is established by using FLUENT software.The average temperature of radiator room is derived by using the finite volume method.And the functional relationship of the average temperature of radiator room,the inlet temperature of radiator and the flow of radiator is established.After bringing the functional relationship to the model of heat meter without flow meter,the correctness of the functional relationship is verified through simulation results.
