本文提出了一种新型四换热器流程太阳能辅助多功能热泵,不但具有家用冷暖空调、热泵热水器和太阳能热水器这三种家用节能产品所包含的制冷、制热和制热水功能,而且具有制冷兼制热水、太阳能辅助制热、太阳能辅助制热水、热水除霜等四种更加节能的新运行模式来实现这三项功能。在自行搭建的实验装置上成功地实现了七种热泵运行模式之间的平稳过渡和高效实现。太阳能辅助制热和太阳能辅助制热水模式的实验结果表明,该新型太阳能辅助多功能热泵可以利用太阳能来实现较高的室内制热效率和制热水效率。不但大幅提高了设备的利用率,而且可以更好地适应不同季节的气候条件,起到显著的节能效果。
This paper presents a new four-heat exchanger process solar assisted multi-function heat pump, not only has the home heating and air conditioning, heat pump water heaters and solar water heaters, three household energy-saving products contained in the refrigeration, heating and heating water features, And the system of hot water, solar assisted heating, solar assisted hot water, hot water defrost four more energy-efficient new mode of operation to achieve these three functions. On the self-built experimental device, a smooth transition and efficient implementation of seven heat pump operation modes are successfully achieved. Experimental results of solar assisted heating and solar assisted heating water mode show that the new solar assisted multifunctional heat pump can utilize solar energy to achieve higher indoor heating efficiency and heating water efficiency. Not only significantly improve the utilization of equipment, but also to better adapt to different seasons of the climatic conditions, played a significant energy saving effect.
