Abstract
In order to solve the problem of thermodynamic imbalance commonly existing in the heating system, an adjustment method that can realize the uniform heating to a building is put forward. In the single pipe system, it regulates the flow based on the energy balance between the heat of system supply for users and the heat dissipation of radiator to indoor, reversing the direction of the supply water and return water. By means of theoretical analysis, the results indicate that this method can solve the problem of building overheating, and the energy saving rate is higher than 30%. This method can also solve the problem of uneven heat and cold of the building by adjusting the ratio of positive and reverse times.
