定静压变风量系统静压设定值的确定方法
Static pressure setpoint determination method for the fixed static pressure control VAV system
摘要:
确定合适的静压设定值是定静压控制的变风量空调系统节能、稳定运行的关键。介绍了国外定静压控制的变风量空调系统静压设定值的确定方法,并运用该方法对一实际系统进行研究。提出了先确定最不利环路,再确定风系统的静压设定值的现场改进调试方法,并在同一项目中运用两种方法分别确定了系统的静压设定值,其得出的结果相同。两种方法均能较为准确地确定合适的静压设定值,对定静压变风量空调系统的调试与运行有参考价值。
Abstract:
Suitable static pressure setpoint is the key to the energy-saving and stable operation for the VAV system. Presents a foreign determination method, and applies it in a real VAV system. Puts forward an improved method which identifies the index circuit first and then figures out static pressure setpoint. Applies these two methods in the same system to determine the system static pressure setpoint respectively and their results are equal. These two methods can both find suitable static pressure setpoints and are useful for the commissioning and operation of VAV systems.
