摘要
分析多区域变风量空调系统常用新风控制策略的特点,为满足该空调系统新风按需控制的要求及降低新风能耗,提出新风循环再利用变新风量控制策略,并介绍该控制策略在实际项目中的实施方法。最后通过实际项目(750 m2的办公楼)对采用新风循环再利用变新风量控制策略的空调系统能耗进行分析,分析结果表明:采用新风循环再利用变新风量控制策略比采用最不利新风比控制策略每天可节约新风电耗24 kW·h。
The common fresh air control strategies for multi-zone VAV(variable air volume)air-conditioning system are analyzed.In order to meet the requirements of demand-controlled fresh air and reduce the fresh air energy consumption of multi-zone VAV air-conditioning system,the variable fresh air volume control strategy of fresh air recycling is proposed,and the implementation method of the control strategy in the actual project is also introduced.Finally,through the actual case(750 m2 office building),the energy consumption of the air-conditioning system using variable fresh air volume control strategy of fresh air recycling is analyzed.The analysis results show that using the variable fresh air volume control strategy of fresh air recycling,the fresh air energy consumption is reduced by 24 kW·h every day compared with that using the most unfavorable fresh air ratio.
