摘要：

针对低温热泵用压缩机存在的问题，研究分析压缩机容积比对其性能的影响，提出一种新型三缸双级变容积比压缩机，并结合实验对搭配同一末端的传统双级压缩系统与三缸双级变容积比压缩系统的性能进行对比分析．研究结果表明：三缸双级系统可在－30 ℃环境正常运行，系统的性能系数(COP)为1.52，而传统双级系统在该种情况下无法运行；三缸双级系统的COP在任何环境温度下均比传统双级系统高1.25%～12.41%.当环境温度一定时，随着供水温度的升高，末端散热量增加，外机最大制热量衰减，COP下降；当环境温度分别为7 ℃和－25 ℃时，供水温度从40 ℃升至55 ℃的过程中，三缸双级系统的COP分别比传统双级系统高1.15%～8.86%和4.32%～7.33%.所有实验工况下，三缸双级系统单位时间耗电量均比传统双级系统低3.78%～16.67%.

Abstract:

Aimed at the problem of the compressors of the low temperature air source heat pump system, this paper analyzes the impact of volume ratio on performance and proposes a novel three-cylinder two-stage variable volume ratio rotary compressor. The performance of the proposed compression system is compared with that of the traditional two-stage compression system of the same terminal in the experiments. The results show that the three-cylinder two-stage system operates in a stable manner with a coefficient of performance (COP) of 1.52 at a ambient temperature of -30 ℃,while the traditional two-stage system does not work. The COP of the three-cylinder two-stage system is always 1.25% to 12.41% higher than that of the traditional two-stage systems at any ambient temperature. When the ambient temperature is stable and the water supply temperature increases, the amount of dissipated heat at the terminal increases. At the same time, the maximum heat of external machine decreases, as well as the COP. When the ambient temperature is 7 ℃ and -25 ℃ respectively, and the water supply temperature changes from 40 ℃ to 55 ℃,the COP of the three-cylinder two-stage system is 1.15% to 8.86% and 4.32% to 7.33% higher than that of the traditional two-stage system, respectively. The power consumption of the three-cylinder two-stage system is always 3.78% to 16.67% lower than that of the traditional two-stage system.
