Design and Realization of a Portable Constant Air(CA) Sampling Pump 便携式恒流空气采样泵的设计与实现
I completed experiment of constant air volume system and variable air volume system of the simulation systems in the laboratory. 在实验室里完成了模拟系统中的定风量一次回风系统和变风量系统的实验。
Finally conducts a deepening research and redevelop on the control strategy and system scheme for the on-off constant air volume air conditioning system which configured the new type fresh air handling unit, designs a set of practical control system for hospital air conditioning system. 最后对配置了新型新风专用处理机组的双位定风量空调系统的控制策略和系统方案进行了深化与再开发,设计出一套实用的医院空调系统的控制体系。
Analyses the temperature control rules to realize economic operation of constant air volume systems. Proposes an improved control strategy based on the indoor temperature control. Compares the energy consumption of HVAC systems in different strategies by using a simulation program. 分析了在定风量系统中实现经济运行的温度控制原则,提出了考虑室内温度控制的新风系统经济运行控制策略,利用模拟程序对不同控制策略下的空调系统能耗进行了比较和分析。
However, the characteristic of VAV system is multivariable, strong coupling, time-varying and nonlinear. So its operation and control will be more difficult than constant air volume air conditioning system. 但是,变风量空调系统具有多变量、强耦合、时变、非线性的特点,因此它的运行和控制都会比定风量空调系统难度大。
