太阳能光热空气源热泵制热技术研究综述

Research Overview on Heating Technology of Solar-Thermal Air Source Heat Pump

有利于节能减排及国家能源结构战略性调整的太阳能光热空气源热泵,作为重要的太阳能结合空气能制热技术,在直膨式、水箱换热式、相变蓄热式等系统结构的研发方面,已经取得长足进展。直膨式太阳能热泵的制热性能系数,相比于常规空气源热泵可提高25%以上,相当于电热水器的3倍以上、冷凝式燃气炉的1.3倍以上;水箱换热式制热系统相比常规的热水及空调系统的全年平均节能率,可达25%以上;相变蓄热式系统的制热性能系数普遍可达3.31以上。面对"十三五"阶段全国加速城镇化的新常态,研究路线需要更加偏向适用于高层建筑用户,即将庞大、分散的系统结构集成一体化,以适应广大高层建筑用户垂直、狭窄的外立面安装环境。

As an important heating technology with both solar energy and air source, solar- thermal air source heat pump has made great progress in different kinds of system structure, such as direct expansion type, tank heat type and phase change heat storage type, in favor of energy saving and emission reduction and the national strategic adjustment of energy structure. The coef- ficient of performance （Cp） of solar-thermal heat pump of direct expansion type increases by more than 25% compared with that of conventional air source heat pump, which is equal to more than three times that of electric water heater and 1.3 times that of gas-fired boiler of condensing type. The tank heat type has an annual average energy saving rate 25%when compared with conven- tional domestic hot water and air conditioning systems. The Cp of phase change heat storage type is generally higher than 3.31. Facing the new normal of accelerating the urbanization across the nation in the ＂13th Five-Year Plan＂ stage of China,the research route needs to be more suitable for high-rise building users,which combines the large and distributed system structure into integra- tion so as to adapt to the narrow and vertical facade installation environment of general high-rise building users.
