 摘要： 对以太阳能热源作为驱动热源的溴化锂第二类吸收式热泵系统进行研究。根据热泵系统在运行过程中的能量守恒与质量守恒关系，计算得出了基于太阳能热源的第二类热泵系统的各部件的相应的参数。利用MATLAB软件建立了该系统的数学模型，并且对该模型进行了仿真模拟。然后对仿真数据分析，得出各部件参数变化对系统性能的影响。最终，溴化锂第二类吸收式热泵系统在设计条件下运行得到的系统性能系数（COP）值为0495左右，这与理论值基本吻合，与相关的实验研究数据也基本吻合。

 Abstract: The system of the absorption heat transformer driven by solar energy was studied in this article. According to the relation of the energy conservation and mass conservation, the parameters have been calculated. The system′s mathematical model was established in the MATLAB software. The model has been simulated by using software. The changes of the system performance have been observed by changing the input parameters of the components. The influence of some major parameters on the system was analyzed using the program. In the end, the system′s COP is about 0495, when it operates under the design condition. This is consistent with the theoretical value and the related experimental data.

 Key words: LiBrH2O absorption heat transformer; solar heat source; solar collector
