摘要
采用室外空气干球温度与比焓作为风侧经济器使用与否的判定条件,对新风免费冷却节能状况进行分析,提出了新风免费冷却节能效果评价指标———新风免费冷却节能率。应用该指标分析了我国不同气候条件下6个典型城市的3种不同类型建筑新风免费冷却节能效果,结果表明,北方严寒及寒冷地区节能率较高,夏热冬冷及夏热冬暖地区次之,温和地区节能率较低。宾馆建筑全年新风免费冷却节能率低于同一地区办公建筑和商场建筑。
Taking the dry-bulb temperature and specific enthalpy of outdoor air to judge whether using an air-side economizer, by analysing the energy saving status of fresh air free cooling, puts forward an energy saving evaluation index for fresh air free cooling--energy saving rate for fresh air free cooling. Adopting the index, analyses the energy saving status of fresh air free cooling applied to three types of buildings in six typical cities with different climate conditions. The result shows that the energy saving rate is higher in the northern severe cold and cold areas, followed by the hot summer and cold winter and hot summer and warm winter areas, and the lowest in the warm area. The rate for hotel buildings is lower than that for office buildings and shopping buildings.
