【摘要】：随着科学技术能力的不断发展和人类生活水平的提高，供热系统和制冷系统出现多元化发展，伴随着的能源的过度采集与消耗也日益严重，建筑节能越来越受到人们的关注。平衡阀产品在水系统中的合理利用可有效减少水力失调现象，取得显著的节能效益。因此在当前我国建筑节能减排、世界性的能源供应日趋紧张的形势面前，具有重要意义。本文针对空调水系统的调节性能，以实现系统的全面水力平衡为主要目的，首先对调节阀在整个管网中的流量特性、平衡阀的分类及工作原理进行了研究，其次分析了水力失调现象对系统产生的危害并提出相应的解决措施，然后论述了平衡阀产品对于解决暖通空调水系统中水力失调问题的意义，特别阐述了空调水系统不同部分的平衡阀的布置方法，并对一些工程实践中经常出现的水力平衡问题进行了分析和解释。通过对三个工程实例的平衡阀节能改造，提高了系统的自控精度，实现了温湿度的稳定调节，保证了日常生活的运行，节约了能源，降低了运行费用；并且通过三个改造实例，验证了平衡阀在水系统中的可行性，为以后解决此类问题，提供了一定的思路和方法，希望为日后的水力平衡技术发展做出贡献。
[Abstract]:With the continuous development of science and technology and the improvement of human living standards, the heating system and refrigeration system appear diversified development, accompanied by excessive acquisition and consumption of energy is increasingly serious. The reasonable use of balance valve products in water system can effectively reduce the phenomenon of hydraulic imbalance and achieve significant energy-saving benefits. Therefore, at present, building energy conservation and emission reduction in China. The world energy supply is increasingly tight in front of the situation, has important significance. Aiming at the regulating performance of air conditioning water system, the main purpose of this paper is to realize the overall hydraulic balance of the system. Firstly, the flow characteristics of the regulating valve in the whole pipe network, the classification and the working principle of the balance valve are studied. Secondly, the harm of hydraulic maladjustment to the system is analyzed and the corresponding solutions are put forward. Then, the significance of balancing valve product in solving the problem of hydraulic imbalance in HVAC water system is discussed. In particular, the arrangement method of balancing valves in different parts of air conditioning water system is expounded, and the problems of hydraulic balance that often occur in engineering practice are analyzed and explained. By reforming the balance valve of three engineering examples, the automatic control precision of the system is improved, the temperature and humidity are adjusted stably, the operation of daily life is ensured, the energy is saved and the running cost is reduced. The feasibility of the balance valve in the water system is verified by three examples. It provides some ideas and methods for solving this kind of problems in the future and hopes to contribute to the development of the hydraulic balance technology in the future.
