摘要(Abstract):

介绍了涡旋式制冷压缩机经济器系统,并对其在空气源热泵系统中的应用进行详细的热力学分析。经过测试,结果表明,涡旋式压缩机经济器系统可以明显提高寒冷地区冬季制热量,极大地改善了空气源热泵的低温适应性。通过研究分析,找到了补气压力对经济器系统性能的影响规律,为找出特定工况下的最优补气压力值提供了理论依据。
The heat pump cycle employing scroll compressor with an ecomizer is introduced in detail and its characteristics are analyzed thermodynamically.Then,through some spot tests,the results show that the cycle can improve the adaptability of heat pump in low ambient temperature environment.Further more,the role is discovered by analyzing the economizer pressure′s influences on the performances of heat pump,which provides great convenience to application.
