摘　　要：以空气源热泵为热源设备,辐射地板为加热末端建立实验系统,基于双气候补偿冬季供暖模式进行监测与分析。在不同的室外环境下,分析出地板辐射系统对室内供热效果、各子系统的温度变化、制热性能的影响规律。为夏热冬冷地区的空气源热泵供暖的发展和提高系统的能效特性提供理论基础和实验依据。结果表明:夏热冬冷地区采用空气源热泵供暖的室内温度为17.0~23.0℃,湿度为25%~45%。采用双气候补偿技术时,室外温度波动会影响主机供水温度、地暖供水温度,并提高室内舒适度。空气源热泵供暖系统的平均小时制热性能比为2.90,双气候补偿对系统能效影响较小。An experimental system is built with air-source heat pump as the heat source equipment and the radiant floor as the heating end.The monitoring and analysis are based on the dual climate compensation winter heating mode.In different outdoor environments,the effects of the floor radiation system on the indoor heating effect,temperature changes of various subsystems and heating performance are analyzed.It provides a theoretical basis and experimental basis for the development of air-source heat pump heating in hot summer and cold winter regions and improving the energy efficiency characteristics of the system.The results show that the temperature of the heating room with air source heat pump is between 17.0-23.0℃,and the humidity is between 25%-45%.When the dual climate compensation mode is used,the outdoor temperature fluctuations will affect the main unit water supply temperature,the floor heating water supply temperature,and improve indoor comfort.The average hourly heating performance ratio of the air source heat pump heating system is 2.90.Dual climate compensation has less impact on energy efficiency.
