空调系统部分负荷下的性能受制于其调控方法和策略,本文通过建立空调系统数学模型并构建实验装置对其进行验证,基于所建立的空调系统模型逐一研究了部分负荷下系统冷冻水流量、冷却水流量、冷却塔风量、空调箱风量的调控对系统性能的影响规律,获得了各参数对系统调控的优先级与节能潜力,在此基础上,研究并获得了系统全局综合调控下的节能策略与节能潜力。结果表明,在系统部分负荷下,通过系统全局优化控制,相比定流量运行,当负荷率为0.6时,系统节能率可达11.7%。
The performance of air conditioning system under partial load is controlled by its control methods and strategies. In this paper, the mathematical model of air conditioning system and the establishment of experimental equipment to verify its performance. Based on the established air conditioning system model one by one under the part load system chilled water flow, cooling Water flow rate, cooling tower air volume, air conditioning air volume control on the system performance rules, access to the various parameters of the system regulation priority and energy saving potential, on this basis, the system under the comprehensive control of energy-saving strategy With energy saving potential. The results show that under system partial load, compared with the constant flow operation, the system energy saving rate can reach 11.7% when the load rate is 0.6 through the system global optimization control.
