| 中文摘要: |
| 节能的分析及优化已不仅仅是能的量的问题，而是能的质与量的综合评价的问题。采用yong分析方法得出空气源热泵空调系统的能耗分布，明确系统yong损失较大的环节。从yong分析得知：压缩机的yong损失占机组能耗的20．5％，冷凝器的yong损失接近总能耗的30％。由此提出了空气源热泵空调系统的节能措施，即应该选用高效率的压缩机，采用强化传热措施，提高传热系数，减小传热温差，同时还应注意改善热泵机组的周围环境，使系统yong损失最小，yong效率最大，实现空气源热泵空调系统的节能优化. |

| With the exergy analysis method in this paper, the exergy loss distribution of air-source heat pump air-conditioning system was obtained, and its main exergy loss has been defined: the exergy loss of the compressor and condenser are about 20.5% and 30% of all the energy loss, respectively. According to this analysis, some energy-saving measures for this system were presented, i.e. the use of a compressor with a high efficiency, and heat transfer augmentation, increasing the thermal conductivity and decreasing the temperature difference for reducing the exergy loss of the condenser. In addition, the ambient for the heat pump unit ought to be improved, in order to minimize the exergy loss of the system, maximize the exergy efficiency of system, and thus to optimize the energy-saving of the air-source heat pump system. |
