摘要
以哈尔滨、北京、上海和广州四个城市为代表的气候区,研究新风系统分别在制冷和制热工况下的温度交换效率和焓交换效率,旨在为设计人员和使用者选择新风系统提供参考。测试工况室内侧依据标准要求,统一按制热工况(21℃,13℃),制冷工况(27℃,19.5℃)参数设定。制冷工况室外侧干球温度由30.7℃上升到35℃;制热工况室外侧干球温度由-27.1℃上升到5.2℃;无论是制冷工况还是制热工况,室外侧温度逐渐升高,交换效率也不断升高,温度交换效率升高较焓交换效率更加明显。
In order to provide reference for designers and users to select outdoor air system,four cities were chosen-Harbin,Beijing,Shanghai and Guangzhou as representatives of different climate regions to research the temperature exchange effectiveness and enthalpy exchange effectiveness of outdoor air system in refrigeration and heating conditions.According to standard requirements,the indoor working conditions are set in accordance with the heating working conditions(21℃,13℃)and refrigeration working conditions(27℃,19.5℃).The outdoor dry bulb temperature of refrigeration working condition is 30.7℃to 35℃,and heating working condition of outdoor dry bulb temperature is 27.1℃to 5.2℃.Whether refrigeration condition or heating condition,the exchange effectiveness increased with the rising of outdoor temperature,and the temperature exchange effectiveness increases more than that of enthalpy exchange effectiveness.
