摘　　要：基于清华大学超低能耗示范楼热电冷联供平台.对利用吸收式热泵回收天然气烟气冷凝热进行了实验研究,分析了余热回收系统的开启、变工况和关机动态响应过程。实验表明,烟气余热回收系统的开启过程较长.应尽量使内燃机与热泵的容量匹配,缩短开机时间;内燃机发电功率对系统供热功率和供热温度影响较大,对冷凝热回收功率、冷冻水温度和制热COP影响较小;系统供热温度对热泵性能影响较大;应选择合适的关机模式,以保证系统安全、缩短关机时间。Based on the building cooling, heating and power （BCHP） systems of low energy building in Tsinghua University, the experiment studied flue gas latent heat recovery by absorption heat pump, and analyzed the dynamic response of the recovery system. The recovery system had a delay in the opening. The power of gas engine greatly influenced the power and water temperature of heating supply, but made little change on the latent heat recovery power, chilled water temperature, and COP of absorption heat pump. Water temperature of heating supply greatly changed the performance of absorption heat pump. Proper closing model should be taken to ensure the system and to shorten the duration time.
