低温地板辐射供暖热用户前的混水设计

摘要

根据规范要求,低温地板辐射供暖宜采用混水方式设计.对旁通加压、回水加压及供水加压3种混水方式进行了剖析,并绘制了原理图和水压图.分析了各自的适用场合,明确了混水泵及换热站内循环水泵的选择方法.评价了混水方式节材、节能的现实意义,提出了混水装置和小区热力外网的不同连接方式.%According to requirements in the related codes, the low temperature floor panel heating should be designed in a way of mixing water. Analyses the bypass pressuring, return water pressuring and supply water pressuring methods by drawing principle charts and pressure diagrams. By analysing their applicability, provides the selection method of the mixing water pumps and the water circulating pumps in the heat exchange station. Evaluates the practical significance of saving materials and energy for the mixing water system, and proposes different connection modes between the mixing water device and the outer heating network.
