摘要
研发制热能力强、运行效率高、满足室内舒适性要求的低环境温度空气源热泵(低温热泵)是推进寒冷地区可持续供热技术发展的重要任务之一。介绍了近年来日本在低温热泵方面的技术进展,包括改善压缩机、换热器等核心部件性能,制冷循环的优化设计与控制,不间断制热融霜,融霜水排放与防冻结技术等相关内容。
The research goal of the low temperature air source heat pump （LTASHP） is to pursue higher heating capacity, energy efficiency and indoor thermal comfort, and it has become an important task in the promotion of the sustainable heating technologies in the cold area. Presents the technical developments for the LTASHP in Japan including the performance improvement of main components, such as compressors and heat exchangers, the optimization of the refrigeration cycle and control strategy, the frost removal without intermission in heating, the drainage of defrosting water etc.
