【摘要】 太阳能供暖和空气源热泵是两项重要的节能技术,但是由于其自身的缺陷,两者单独应用无法很好的满足供暖需求,因此,两者联合运行是目前的主要研究内容。本文综述了目前国内外在太阳能热泵联合供暖方面的研究成果,主要介绍太阳能热泵系统的一般原理以及直接膨胀式和间接膨胀式两大类太阳能热泵供暖系统的研究情况。在此基础上对联合供暖系统的研究前景进行展望。更多还原

【Abstract】 Solar heating and air-source heat pump,two energy-saving technologies,play an important role in the energy-saving field.However,both of them have their own disadvantages in the field of energy saving application.These two energy-saving technologies cannot meet the requirements of heating alone.Therefore,it is the main research issues to simultaneously adopt the two technologies for heating at present.In this paper,the research achievements of solar heat pump combined heating at home and abroad are reviewed.The general principle of solar heat pump system and the research situation of direct expansion and indirect expansion solar heat pump heating systems are mainly introduced.On this basis,the research prospects of the combined heating system are prospected.更多还原
