热计量采暖系统户间传热与重力作用压头探讨

Study on Heat Transfer between Househould and Pressure Head of Gravity Action for Heating Systems of Individual Househould Heat Metering

对于分户热计量采暖系统,必须计算户间传热引起的热负荷,并将这一热负荷作为散热器选型的依据之一。相对于热水循环泵的作用压头,尽管重力作用压头很小,但它是引起双管采暖系统垂直失调的重要原因,在设计分户热计量采暖系统时,必须充分重视其不利影响。

It is necessary to count heat load caused by heat transfer between househould for heating systems of individual househould heat metering, and the heat load is one basis of choosing radiator. Although pressure head of gravity action is smaller than hot water recycle pump, it is one important cause of leading to vertical imbalance of double pipe heating system. So it must be carefully treated when designing new double pipe heating system of individual househould heat metering.
