在多区域变风量空调及其控制系统的分析研究基础上 ,根据ASHRAE通风标准对新风量的要求 ,针对混合送风系统仿真分析了 4种新风及其分配的控制方案 ,综合考察了各方案的新风分配以及系统能耗。结果表明 ,通过VAV末端再热控制并结合AHU送风温度优化的控制方案 ,可以较好地解决多区域VAV空调系统新风分配问题 ,同时能有效地降低系统的能耗。
Based on the analysis and research of multi-zone VAV air-conditioning and its control system, according to the ASHRAE ventilation standard’s requirements for fresh air volume, four kinds of fresh air and its distribution control program were simulated and analyzed for the mixed air supply system. Fresh air distribution and system energy consumption. The results show that the VAV end reheat control combined with the AHU air supply temperature optimization control scheme can better solve the new wind distribution problem of the multi-zone VAV air conditioning system, and can effectively reduce the energy consumption of the system.
