【摘要】 提出了一种太阳能与多功能热泵技术有机结合的间接膨胀式太阳能多功能热泵(IESA-MDHP)系统.描述了间接膨胀式太阳能多功能热泵系统的组成及工作原理,并阐述了各种功能模式的运行条件和运行方式.重点对研制的IESA-MDHP实验样机的供热性能进行了实验研究.实验结果表明,IESA-MDHP系统的COPhp在3.30~4.71之间变化,而COPsys在2.88~3.96之间变化,明显高于传统的家用空气源热泵系统,但烟用性能系数在0.17~0.31之间变化.更多还原

【Abstract】 An indirect expansion solar assisted multifunctional domestic heat pump（IESA-MDHP） was proposed.Different operation modes in different conditions were presented.The experimental investigation of a prototype of the IESA-MDHP in heating mode was conducted.The results indicate that the IESA-MDHP’s COP_hp ranges from 3.30 to 4.71 and the COP_sys varies between 2.88 and 3.96,apparently higher than that of the conventional domestic air-source heat pump,and the COP_EX ranges from 0.17 to 0.31.更多还原
