太阳能综合利用教学、实训装置的研发(VI)——太阳能—空气双源热泵热水系统

Development of Teaching and Training Device for Comprehensive Utilization of Solar Energy(VI): The Hot Water System with Hybrid Heat Pump Powered by Solar Energy and Air

作者研究发的太阳能-空气双源热泵热水系统,将太阳能热泵与水蓄热结合,根据用户的需要和室外气象条件的变化,具有单独太阳能制热水、单独空气源制热水、制热水兼制冷、单独制冷、供暖等多种功能,可以节约能源,减少环境污染,是绿色建筑值得推广的一项技术。该系统运行稳定,能效比高,不但可以作为一项新技术在实际工程上推广,而且能够进行科研实验,又可供学生进行系统的测试、调试,作为教学仪器使用。

Hot water system based on a hybrid heat pump powered by solar energy and air （HWSSEA） is developed. HWSSEA is an integration of solar heat pump and water thermal storage. According to the user＇s needs and weather variation, the system is characterized by three patterns including supplying hot water with solar or air energy respectively, hot water and air conditioning simultaneously, and heating and cooling separately. HWSSEA can save high-quality energy and reduce environment pollution, and holds out great application prospects in green buildings. With its stable and reliable performance and high energy efficiency ratio, the system can be not only applied in projects but also in research labs. Besides, it can be used in training courses for students to conduct system test and adjustment.
