1 现有小区管网水平失调的普遍性及造成的问题 1.1 水平失调的普遍性。不论是热电联产大型热网还是锅炉供暖的管网,普遍存在水平失调问题,具体表现在以下三个方面。 1.1.1 靠近热源的前端用户供回水压差大,通过用户的流量大于所需流量,而末端用户压差不足,通过用户的流量少于需要的流量,其结果是冷热不均;还有部分建筑存在浪费热
1 The prevalence of the current misalignment of the community’s pipe network and the resulting problems 1.1 The universality of the imbalance of levels. No matter whether it is a large-scale heat network of cogeneration or a heating network of boilers, there are widespread problems of horizontal imbalances, which are manifested in the following three aspects. 1.1.1 The front-end users near the heat source have a large pressure difference between the return water, the user’s flow rate is greater than the required flow rate, and the end-user pressure difference is insufficient, and the user’s flow rate is less than the required flow rate, resulting in uneven cooling and heating; There is a waste of heat in some buildings
