摘　　要：研究以聚丙烯腈、硅氧烷酰胺和氯化锂为原料制备了复合膜,并以此为热交换膜制作了全热交换装置。通过试验研究了复合膜水蒸气透过率的变化规律,结果表明:复合膜对水蒸气的透过率最高可达39.5×10^(-8)kg/(m^(2)sPa)。当风量为680m^(3)/h时,送风净新风率为98.1%,达到C2泄漏等级。全热回收效率随着风量的增加而减小,在冬季工况条件下,风量为213m^(3)/h时,该装置的全热交换效率可达81.5%。In this study,polyacrylonitrile,siloxanamide and lithium chloride were used as raw materials to prepare composite membrane.And the total energy exchange device was fabricated based on the composite membrane.The variation of water vapor transmittance of composite membrane was studied experimentally.The experimental results show that the highest permeance of the composite membrane for the water vapor permeability can reach until 39.5×10(-8)kg/(m(-8)kg/(m^(2)sPa).When the air volume is 680 m^(2)sPa).When the air volume is 680 m^(3)/h,the net fresh air rate of supply air is 98.1%.The total energy recovery efficiency decreases with the increase of air volume.Under the winter condition,the total energy exchange efficiency of the device can reach 81.5%when the air volume is 213 m^(3)/h,the net fresh air rate of supply air is 98.1%.The total energy recovery efficiency decreases with the increase of air volume.Under the winter condition,the total energy exchange efficiency of the device can reach 81.5%when the air volume is 213 m^(3)/h.
