摘要
从利用低品位和可再生能源出发,提出了多种可用于北方地区供暖和制备生活热水的低蒸发温度吸收式热泵系统形式。结合空气源和地源热泵存在的问题,分析了空气源和地源吸收式热泵在我国北方地区应用的技术方案及其应用潜力。结果表明,NH3-LiNO3工质对具有较好的低温适应性;单级空气源吸收式热泵性能较好,双级和双级耦合吸收式热泵在制取较高温度热水和应用于较低温环境时更具优越性;地源吸收式热泵不仅可以有效减小北方地区土壤热不平衡,还具有较高的一次能源效率。
To make use of low-grade and renewable energy,puts forward several heating and domestic hot water systems based on low evaporating temperature absorption heat pump（AHP）.In the light of the problems of existing air source and ground source heat pumps,analyses the application potential of airsource and ground-source absorption heat pump used in Northern China.The results show that NH3-LiNO3 is more suitable for low evaporating temperature;single-stage air source absorption heat pump（ASAHP） has higher COP,while double-stage and double-stage coupling ASAHP are more advantageous when producing higher temperature hot water or operating in colder climate;and ground source absorption heat pump（GSAHP）can not only reduce the ground thermal imbalance but also provide high primary energy efficiency.
