变流量空调系统设计问题的探讨

Discussion on Designing of Variable Flow Hydronic Systems

简述了变流量系统的发展和国内研究现状,指出这项技术在我国不能广泛应用的原因;结合国外的有关文献分析变流量系统的应用条件及设计中所应注意的问题,对系统所涉及的重要部件进行了分析,包括水泵的选择、旁通管的设计、调节阀和执行器的选择、控制点的位置和设定值的大小、冷冻机的选型和运行次序等;指出随着相关多学科知识的不断发展,系统设计也是不断更新的。

The thesis introduces the development of variable flow hydronic systems and the present condition home andabroad. and indicates the status that why this technique was not generalized in our country. Construes about the applicationsconditions of variable flow hydronic systems and problems that are needed for designing. Analyzes the important assembliesthat related to the systems, including the choices of pump, designs of common pipe, choices of control valves and actuators,locations of the differential pressure transmitters, values of set point and chiller operation sequencings, etc. Points out that withthe fast developing of the correlative knowledge, the system designing should be renovated at any moment.
