摘要
对于冬季仍然要送入冷风来消除室内余热的场所,变频变风量运行不但可以节约风机的运行费用,还可以节省空调系统用于制冷的能量。本文基于Matlab/Simulink仿真平台,模拟了地铁车站冬季最冷天的空调运行能耗。结果证明,变频变风量系统冬季直接用室外冷源制冷节能效果明显。
In cases where cooling is essential even in winter,VAV system can save not only energy consumption of fan but also that of refrigerating system.Based on Matlab/Simulink,the author simulates a subway station＇s air-conditioning energy consumption on the coldest day in winter.Results show that VAV system using the cold outdoor air for cooling in winter has high energy efficiency.
