| 摘 要： | 利用权重系数建立了全热换热器的全热效率、显热效率及潜热效率三者的关系式,根据显热、潜热效率权重系数判定显热效率、潜热效率对全热换热器全热效率的影响程度。夏季工况下,我国大部分地区空调系统中全热换热器的全热效率主要受潜热效率影响。我国西北地区的空调系统不适合使用全热换热器。

| Abstract: | The relational expression for total heat efficiency,sensible heat efficiency and latent heat efficiency of total heat exchanger is established with weight coefficient method.The influence degree of sensible heat efficiency and latent heat efficiency on total heat efficiency of total heat exchanger is determined according to weight coefficient of sensible heat efficiency and latent heat efficiency.The total heat efficiency of total heat exchanger in air-conditioning system is mainly influenced by the sensible heat efficiency under summer conditions in most areas of China.The total heat exchanger is not suitable for air-conditioning system in the north-west region of China. |

| Keywords: | total heat exchanger total heat efficiency sensible heat efficiency latent heat efficiency weight coefficient |
