| | In water-based heating and cooling systems there would be a hyo draulic inbalance in distribution pipeline. It means that there would be an uneven distribution of heat throughout the system. As a result, some room suffer from unsatisfactory temperature and some energy is wasted. In this paper the balancing valve and its intelligent instrument are recommended for realizing hydraulic balance of water pipeline. The balancing principle and application are slso described. It will give a reference to designers an... | | 供热、热水采暖及空气调节水系统中,热(冷)媒的水力输配系统往往存在水力失调。这意味着热(冷)量输配不均匀,导致部分房间过热或过冷,同时浪费能量。本文介绍平衡阀及其智能仪表,它可以实现管网系统的水力平衡,同时还阐述了平衡原理及其应用方法,可供有关人员设计、使用时参考。 | | 文摘来源 | | A comparison is given is detail to two types of cool not water circulating system of the airconditioningplant,i.e.the programming type and non-programming type. Through the disscussion on rariousplants, the paper reveals the programming type plant can considerably minimize the problem of"hydroflowout-of-order",and as a result provide considerable convenience to the running adjustment of the system.The paper also discusses the way of correct and economic selection of pipe diamter,analizes the method of press... | | 本文就空调冷(热)水循环系统的两种形式即同程式和异程式作了详细的比较,并通过实例说明,空调冷(热)媒水循环系统采用同程式大大改善了系统的水力失调现象,给系统的运行调整工作带来了极大的方便。文章对如何经济合理地选择管径作了一定的阐述。文章同时分析了系统的定压方式以及定压点的选择对系统运行的安全性方面所起的作用,结论指出,机械循环闭式水循环系统采用高位水箱定压方式,设备简单、工作安全可靠。 | | 文摘来源 | | Based on analyzing hydraulic stepout and heating power stepout took place in hot water heating system indoor, the improvement plan is presented in this paper. | | 分析了室内热水采暖几种系统中经常出现的水力失调、热力失调问题,并提出了相应的对策意见。 | | 文摘来源 | |   | | << 更多相关文摘 |
