太阳能热泵蓄热系统的实验研究

文章介绍了带有相变蓄热水箱的太阳能热泵系统的运行实验。该系统是在原有的太阳能一土壤源热泵的基础上通过增加一个蓄热装置建立起来，包含太阳能集热器、相变蓄热水箱、双热源（太阳能和土壤）热泵以及末端装置（风机盘管）四个主要部分实验在供暖期末期进行，在整个实验阶段，系统供暖满足率为0．6，平均供热COP达到6.5。

A Research in the Experiments of Thermal Storage System with Solar Energy Heat Pump

The author introduces the operational experiments of solar energy heat pump system with a water tank of phase transition thermal storage. This system is supplemented by a thermal storage device on the original heat pump with solar and soil energy as its source, including a solar heat collector, a water tank of phase transition thermal storage, thermal-operated pump with double heat sources （solar and soil energy） and a terminal device （fan coil）. The experiment is carried out in the last phase of the heating stage. Throughout the whole session, the system reaches 0.6 for heating coverage and 6.5 for average heating COP.
