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。在相同的制热工况、制冷工况参数下,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。新风机组实际安装过程应该因地制宜,选择合适的热交换芯产品,可以节约整体造价,避免资源的浪费。
The temperature exchange efficiency and enthalpy exchange efficiency of outdoor air system under refrigeration and heating conditions were studied in four climate zones represented by Harbin, Beijing, Shanghai and Guangzhou. Under the same heating and refrigeration conditions, the outdoor temperature increases and the exchange efficiency also increases. The increase of temperature exchange efficiency is more obvious than that of enthalpy exchange efficiency. The actual installation process of outdoor air units should be tailored to local conditions. Choosing suitable heat exchange core products can save the overall cost and avoid waste of resources.
