温室太阳能热泵联合供暖系统的性能与效益分析
Performance and economic analysis of a combined heating system of solar energy and ground source heat pump
摘要
Abstract
In response to the low proportion of green energy utilization and waste of light resources in northern greenhouses,a combined greenhouse heating system was used in this study.The operating performance,heating effect and economic space benefit of the coupling application of solar receiving device and ground source heat pump were analyzed.The results show that:1)Compared with a single heat pump heating mode,the combined heating mode can increase the heating capacity by 11.87 to 43.98 MJ on typical sunny days in autumn and winter,and increase the nighttime substrate temperature by a maximum of 2.07 ℃;2)The vacuum tube water collector ground source heat pump combined heating system has the best heating effect in the combined heating system,and can provide heat of 516.30-818.68 MJ on typical sunny days in autumn and winter;3)The combined heating system can promote the growth and development of tomato plants,increase fruit yield by up to 3.22％,and increase production income by 3 000 yuan/hm2;4)Compared to the single heat pump heating mode,the energy-saving rate of the combined heating system has increased by 1.32％.Overall,the combined heating system in this study can be promoted and applied in greenhouses.关键词
