| 摘 要： | 现有热流计都需要流量计来计量流量.流量计很容易损坏并产生计量误差.为了解决这一问题,依据能量守恒提出了一种新型热量计,并对该装置的测量原理进行了理论分析和数值模拟,从而实现了只测量温差的情况下测出用户消耗的热量,摆脱了流量对测量结果的影响,从模拟和理论分析证明本方法能够较准确的计量热量值.

| Abstract: | The conventional heat flow meter needs to measure flow rate.The flow meter is easily damaged and produce errors.In order to solve this problem,a new type heat flow meter based on conversation of energy was introduced.Numerical simulation was used to analyze the theory of measurement.It approves that the measurement of the new-type heat meter has nothing to do with the flow rate.The simulation and theoretical analysis show that the method would be an accurate method of measuring heat. |
