摘要
建立了基于室外空气参数的中央空调全新风运行控制模型,提出了全新风运行节能评价指标—节能指数。应用该指标对我国不同热工分区下的6个典型城市商场类建筑全新风运行节能效果进行了分析,并依据室内设计参数对运行方案进行了优化。结果表明:对于冬季,各气候区均有近100%的时间可采用全新风运行,全年可减少50%~92%的中央空调运行能耗;严寒地区和寒冷地区宜采用全热模式,温和地区宜采用显热模式,而对于夏热地区,两种模式下的节能效果基本一致;全新风运行的节能效益是室内外空气参数综合作用的结果,可以考虑不同的月份采用不同的室内参数设置,以增长全新风运行时间并取得更大节能效益。
Based on the indoor and outdoor meteorological parameters, control model of full fresh air model is established, and an evaluation of full fresh air model that energy-saving index is proposed. The performance of full fresh air model energy-saving in six typical urban residential buildings of different thermal partition is analyzed. Full fresh air model scheme is optimized on indoor design parameters. The results shows that full fresh air model can work in whole winter, and 50%~92% of centralized air-conditioning energy consumption can be reduced in one year. Enthalpy control model can be used in cold regions, and sensible control model can be used in temperate regions, while in hot summer regions the two control models have the same energy-saving effect. Energy-saving performance of full fresh air model depended on the indoor and outdoor meteorological parameters, it is necessary to set difference indoor air parameters in different months in order to increase uptime and achieve greater energy-saving efficiency.
