摘　　要：建立了全热交换器(ERV)的仿真模型并进行了实验验证,比较分析ERV在北京和上海气候条件下、设定温度不同时的显、潜热回收的变化规律以及运行效率的季节特征。结果表明,北京冬季显、潜热回收量的最大值是过渡季和夏季的10倍,上海则为5.5倍,过渡季和夏季的全热回收量与冬季相比是微小的;北京的全年显、潜热平均效率均大于上海;不同气候下的显、潜热效率差别在3.1%和4.3%之内,气候的差异对ERV的运行效率影响不大;两地全年的显、潜热效率都呈现凹型的演化形态,8月的显热效率和5月的潜热效率分别为全年最低。The simulation model of energy recovery ventilator （ERV） was built and validated experimentally, and the sensible heat and latent heat recovery of ERV as well as the operating efficiency were investigated both for Beijing and Shanghai weathers with different temperature set-points. Simulation results show that the maximum value of sensible and latent heat recovery in winter is ten times as much as the counterpart in transitional and summer season in Beijing, while five times in Shanghai. The energy recovery in transitional and summer season is tiny against that in winter. The Beijing annually average sensible and latent heat efficiencies are larger than those in Shanghai. The weather has minor impact on the performance of ERV with the differences of sensible and latent heat efficiencies in 3.1% and 4.3 % for various weathers, respectively. The sensible and latent heat efficiencies for both cities appear show concave in a year scale, whilst the value for sensible efficiency in August, or the valae for latent heat efficiency in May reach the yearly lowest point.
