供暖空调水系统水力平衡

Hydraulic Balance of the Heating and Air Conditioning Water System

对供暖空调水系统水力平衡相关的规范进行了引用,阐述了水力平衡在工程设计的重要意义。以某办公楼水平同程管路的空调水系统为例,通过计算得出,在管路水力平衡设计时,没有必要严格要求所有末端设备保持同程。以某小学散热器供暖系统的两个环路之间平衡为例,当管路服务半径较大时,可以将服务对象划分为若干个区块的并联,同时将较不利区块中,管道较长区块的管道比摩阻控制为较小值。以某小区地下车库街区热水供热管网为例,在异程式系统中,根据各个三通处的资用水头,计算各个三通处两个管路之间的平衡,可以确保达到水力平衡。

Reference to the relevant regulations for hydraulic balance of heating air-conditioning water systems.This article explains the importance of hydraulic balance in engineering design.Taking the air-conditioning water system of an office building with the same level of pipeline as an example,it is calculated that in the hydraulic balance design of the pipeline,it is not necessary to strictly require all the end equipment to maintain the same distance.Taking the balance between two loops of a radiator heating system in a primary school as an example,when the service radius of the pipeline is large,the service object can be divided into parallel connection of several blocks.At the same time,the pipe specific frictional resistance of the the longer block can be controled at a lower value in the more unfavorable blocks.Take the hot water heating pipe network in the underground garage area of a certain residential area as an example.In the direct return system,the balance between the two pipes at the three outlets can be calculated according to the water heads at the three outlets to ensure that the hydraulic balance is achieved.
