| 摘 要： | 在风机盘管加新风空调系统中,风机盘管干工况时只承担少部分室内瞬变负荷,由于干工况下新风机组需处理的新风焓差大,存在着干工况应用困难的问题.采用空气-空气能量回收装置(AAERE)预处理新风,可以解决风机盘管干工况运行中的困难.结果表明:采用AAERE回收部分余热预处理新风,可以降低新风机组需处理的焓差值,使用热回收后新风处理焓差值降低为33.6 kJ/kg,供冷量节约16.2%,使空调系统经济运行得到保障.

| Abstract: | Fan coil units assume only some part of indoor instantaneous changeable load on dry coil condition in primary air fan-coil system,but the enthalpy difference in fresh air that need the outside air units to treat is too large,so the application of dry coil condition is limited.Using air-to-air energy recovery equipment(AAERE) to pretreat fresh air can solve the problem of the application of dry coil condition.The result indicated,recovery of waste heat by the AAERE to pretreat fresh air can reduce the enthalpy difference to 33.6 kJ/kg,and save the cooling-capacity of outside air units by 19.4%,so the economy operation of the air conditioning system can be assumed. |
