摘　　要：为降低空调在使用新风功能时的耗电量,提出一种利用热泵技术对排风进行热回收的技术方案,选取一款3匹的风管机作为研究对象,在南京市气象条件下,使用美的自研制冷系统仿真软件MCOOL建模,对其节能效果、经济性等指标进行理论分析,结果表明对比基础型风管机,对于制冷和制热工况,在相同能力下,排风热回收技术可使压缩机频率分别降低3 Hz~15 Hz和1 Hz~5 Hz。新技术制冷季节可节省电量330.5 kW·h,制热季节可节省电量304.6 kW·h,年省电量可达635.1 kW·h,节能效果明显;估算排风模块的成本增加额,计算投资回报率(ROI)达到83.2%,经济价值较高。To reduce the power consumption of air conditioning when using fresh air function,a technical scheme using heat pump technology for heat recovery of exhaust air is proposed.A 3-horsepower air duct unit is selected as the research object.Using Midea's self-developed refrigeration system simulation software MCOOL under Nanjing city meteorological conditions,theoretical analysis is carried out on its energy-saving effect and economic indicators.The results show that compared with the basic air duct unit,for cooling and heating conditions,under the same capacity,exhaust heat recovery technology can reduce the compressor frequency by 3 Hz~15 Hz and 1 Hz~5 Hz respectively.The new technology can save 330.5 kW·h of electricity in the cooling season and 304.6 kW·h of electricity in the heating season,with an annual electricity savings of up to 635.1 kW·h,and the energy-saving effect is significant.The additional cost of the exhaust module is estimated,and the return on investment(ROI)is calculated to reach 83.2%,indicating a high economic value.
