中文摘要：
对一种新型太阳能多功能热泵系统（SA—MDHP）进行了[火用]分析；并列出了SA—MDHP系统各部件的[火用]方程，将各部件输出的[火用]功率与输入[火用]功率的比值定义为部件的[火用]效率；研究结果表明，在给定条件下，SA—MDHP系统4用效率在0．15—0．4之间变化；为了有利于提高系统的[火用]效率，对各个部件火用损率变化趋势和各部件[火用]损率变化值进行了模拟研究，从研究结果可知，SA—MDHP系统[火用]损率最大的部件是压缩机，而火用损率最小的部件是毛细管。
英文摘要：
The exergy analysis of a prototype of a novel solar assisted multifnnctional domestic heat pump（SA-MDHP） in heating mode was conducted. The exergy equations of every component of SA-MDHP are presented. The exergy efficiency, defined as the ratio of the outlet to the inlet exergy flow in every component of SA-MDHP cycle, is determined taking into account the parameters and performance coefficients. The results indicate the exerg3, efficiency of the system based on the second law of thermadynamics varies from O. 15 to 0.40 in this conditions. The exergy destructions in various components are presented for improvement of its performance. The component of the maximum exergy destruction of SA-MDHP is the compressor, and the component of the minimum exergy destruction is the capillary in SA-MDHP.
