太阳能与空气源热泵联合集热工程系统开发与实践

System Development and Practice of Central Heating Engineering by Solar Energy Integrated with Air Source Heat Pumps

在人员居住密集的建筑物中利用太阳能规模化集热制取生活热水是一种有效的建筑节能手段,但单纯的太阳能热利用受制于气候因素无法稳定供热,因此需要寻找一种辅助能量供应形式,以保证系统能够全天候稳定供热。本文探讨了使用压缩式空气源热泵技术作为规模化太阳能集热系统辅助热源的技术与经济可行性,并开展了系统的工程实践工作。研究工作表明,压缩式空气源热泵是太阳能规模化热利用系统比较理想的一种辅助热源形式,能够解决系统能量供应的稳定性和经济性双重瓶颈问题。

In the crowdedly inhibited buildings, it is an effective energy-saving approach to massively produce the domestic hot water from solar energy. However, the stability of the single solar energy system is confined by the climate and weather factors. It is necessary to find an aux-energy to ensure the stable heat supply in all weather. In this paper, the compression heat pump of air source as the aux-energy source for large scale solar collector system was discussed of technological and economic feasibility. Then the systematic engineering practice was carried out. The research proved that compression heat pump of air source can be an ideal aux-energy for large scale solar heating engineering, and it can better balance the bottleneck problems in the stability and economical efficiency of the system energy supply.
