摘要 ：
The indoor space of residential building is limited, especially in building retrofit, to improve the indoor space utilization and the performance of exhaust air heat recovery system, a novel dual-cylinder rotary compressor with independent suction and discharge ports was designed to drive an inverter parallel-loop exhaust air heat pump. Through the experiments and analyzing the parallel-loop exhaust air heat pump system working characteristics under variable compressor frequency and different fresh air volume flow rate, the optimized method is proposed and verified experimentally. Finally, the annual energy efficient operation plan was proposed, and the seasonal performance factor and seasonal average input power under this operation plan in three typical countries/organization were calculated. Results show that the system COP can be greatly improved by applying a mixed air supply method during winter. When the fresh-air-to-return-air ratio is 1:1 and the outdoor temperature is -5 degrees C, the system COP reached 10.18, which is the highest comparing with the related studies. In summer, the system COP is increased by increasing the ventilation volume flow rate. When the operation of the parallel-loop exhaust air heat pump system follows the energy efficient operation plan to ensure the temperature effectiveness over 100% and the outdoor working condition complies with GB 21455-2013, the heating season performance factor, heating season average input power, cooling season performance factor, and cooling season average input power are 7.22, 0.6909 kW, 2.83, and 0.8167 kW, respectively. The work would provide guidance for the development of exhaust air heat recovery system in residential building.

摘要 ：
A novel dual-cylinder rotary compressor was designed to improve the indoor space utilization, and it was used to drive a parallel-loop exhaust air heat pump (PEAHP) which integrates the functions of heating, cooling, ventilation and heat recovery. The operation characteristics of the system in different compressor frequencies and different fresh-air-to-return-air ratios (FRRs) were studied and analyzed experimentally. Through the simulation of the ultra-low energy buildings (ULEBs) in 12 cold zone cities, the hourly (8760 h) building thermal loads in the whole year are calculated. On the basis of the matching of the hourly system working characteristics and the thermal loads of ULEB, the energy efficient working strategy is proposed. Finally, the applicability and energy consumption of the PEAHP system applying in ULEBs were analyzed. The results show that, the system heating/ cooling capacity and COP can be considerably improved by increasing return air volume flow rate. In winter, under the working condition of 50 Hz-FRR 1:1, the peak heating capacity and COP are 8.94 kW and 9.63, respectively, which are 77.38% and 64.05% higher than those when FRR is 1:0. In summer, when the outdoor temperature ranges from 26 ?to 40 ?, the system temperature effectiveness is higher than 1 in all working modes. The PEAHP system has great applicability for ULEBs in cold zone of China during winter, and the system can meet the year-round use demands of the ULEBs in Taiyuan, Dalian, Lanzhou, Yinchuan and Lhasa, with the unsatisfied heating/cooling time ratio of 1.61%, 0.09%, 0.006%, 2.45% and 0.02%, respectively.

摘要 ：
A mechanically-driven loop heat pipe heat rec?overy system by booster and refrigerant pump was proposed to match the all-year fresh air load varying greatly with ambient temperature in an energy recovery ventilation unit and enhance its energy-saving potentials. The system prototype was developed and the experimental setup established in which the booster and pump can operate together or separately. Namely, the prototype could be running in pump-driven loop heat pipe (PLHP) mode, booster-driven loop heat pipe (BLHP) mode or booster combining with pump-driven loop heat pipe (CLHP) mode. The heat transfer characteristics of the prototype running in these three modes under winter and summer conditions were studied, respectively. The results showed that the temperature effectiveness of CLHP was greater than that of PLHP or BLHP under all-year conditions. When outdoor temperature is -15 ?degrees C, the temperature effectiveness of CLHP is 78.0% and 52.5% higher than that of PLHP and BLHP, respectively, and the heating EER of CLHP is 29.6% higher than that of BLHP. When outdoor temperature is 40 ?degrees C, the CLHP has 19.5% higher of temperature effectiveness and 21.7% higher of cooling EER comparing with the BLHP, respectively. In winter, BLHP performs better when outdoor temperature is greater than 7.5 ?degrees C while CLHP performs better when outdoor temperature is lower than 7.5 ?degrees C. And BLHP has better performance when outdoor temperature is lower than 35 ?degrees C in summer while CLHP performs better when outdoor temperature is higher than 35 ?degrees C. The composite system can switch its operating mode according to the fresh air load, which can improve effectively the year-round performance of the system to recover heat in building ventilation.

摘要 ：
工质泵是泵驱动两相回路的关键驱动部件,在整个系统中起着决定性的作用。为研究工质泵的内部工作特性,建立旋涡泵三维模型并提取流体域,对基于制冷剂R22的旋涡泵的工作过程进行模拟。研究结果表明:进口压力从0.95MPa增至1.25MPa,到达稳态的迭代次数缩减一半以上,最大总体积分数从0.6降至0.007;旋涡泵稳态运行时,叶轮受到的离心力作用使叶轮外边缘处总压力分布大于叶轮内边缘处约0.1MPa。叶轮汽蚀破坏区域位于泵进出口叶轮内边缘,此处是泵内叶轮待改进设计的区域。

摘要 ：
<正>项目背景及研究意义空气源热泵是从室外环境空气中获取热量并提升品位后用于供热,以及从室内环境中取热并排放至室外环境空气从而实现室内制冷的装置或系统。由于其适用性强、结构紧凑、调控方便、能源效率高等优点,得到了广泛使用。由于环境空气温度变化范围大,空气源热泵性能在偏离设计工况时性能衰减严重。因此,发展能兼顾制冷和制热性能的高适应性空气源热泵对于我国建筑节能至关重要。在此背景下,自1990年代末开始,项目完成单位在该领域开展了大量研究工作。
