In the light of the engineering characteristics and climate conditions, the project adopts the heating system of solar energy plus low temperature type air-source heat pump. Presents the design of the system and its control requirements. The, system adopts passive heating mode to satisfy the demand for heating during abundant sunshine periods and active heating mode during the other periods. In areas with abundant sunshine, using the solar energy and heat pump heating system reasonably and effectively can save system operation costs and reduce environment pollution caused by burning fossil fuels.%结合工程特点和气候条件,该工程采用了太阳能+低温型空气源热泵供暖系统.介绍了系统设计及其控制要求.在日照丰富的时段,采用被动式供暖方式满足室内供暖需求；在其他时段,则采用主动式供暖方式.在日照丰富的地区,合理有效地利用太阳能和热泵供暖系统,不仅能节省系统运行费用,同时也可减轻燃烧矿物燃料带来的环境污染.
