空气热能是储存在环境空气中的太阳能。空气热能具备符合国内外对于可再生能源的定义的属性:从自然界直接获取,且具有可再生性。空气热能储量丰富,开发利用技术相对成熟。将空气热能纳入可再生能源范畴,既有利于我国节能减排目标的实现,也具有可观的经济效益。本文介绍了空气热能的属性及特点,并讨论了空气热能利用的技术路径及空气源热泵系统性能评价的方法及指标,以期为空气热能纳入可再生能源范畴提供理论基础及技术参考。
Air Heat is the solar energy stored in the ambient air. Air heat has attributes that meet the definition of renewable energy at home and abroad: directly from nature and renewable. Air thermal energy reserves, development and utilization of technology is relatively mature. The air heat into the category of renewable energy, both conducive to the realization of China’s energy-saving emission reduction targets, but also has considerable economic benefits. This paper introduces the properties and characteristics of air heat energy and discusses the technological path of air heat utilization and the method and index of air source heat pump system performance evaluation in order to provide the theoretical basis and technical reference for the inclusion of air heat energy in the field of renewable energy.
