兰州地区地源热泵与太阳能联合空调系统方案的评价

针对兰州地区冬冷夏凉的气候特点,研究了地源热泵系统与太阳能热水系统联合运行的新型空调系统在该地区的应用。太阳能热水系统可以解决地埋管换热系统冬季吸热与夏季排热不平衡的问题,保证地源热泵系统的稳定高效运行。以兰州新区地源热泵工程为例介绍了太阳能如何与地源热泵匹配的方案,并且对比了联合空调系统与常规空调的运行费用,表明该系统具有技术可行性,可以推广应用。

Evaluation of Ground Source Heat Pump and Solar Energy Air Conditioning System in Lanzhou District

Based on the climate characteristics of Lanzhou district, which winter is cold and summer is cool, we study the application of a new type of air conditioning system in this district, combining the ground source heat pump system and solar energy hot water system. For the underground heat exchange system, the solar water heating system can solve the problem about the imbalance of heat absorption in winter and heat release in summer, which ensures the stable and efficient running of ground source heat pump system. For a project in Lanzhou district, we study the matching scheme of solar energy and ground source heat pump, and compare the operation cost between the joint air condition and the conventional air condition. The result indicates that the technology of joint system is feasible and can be applied to Lanzhou district.
