摘　　要：为降低采暖期能源消耗,实现节能减排,针对北方集中供暖仍采用燃煤锅炉供暖的问题,设计一种太阳能-热泵双水箱集成供暖系统。通过实验,分析系统在采暖季不同气象条件下系统的运行特性。实验结果表明:系统运行稳定,能够满足采暖季不同气象条件下的采暖需求;晴天工况相较于阴晴天和雨雪天工况节能14.4%和17.7%,晴天、阴晴天和雨雪天工况下室内平均温度分别为18.3℃、17.2℃和17℃,系统COP(性能系数)分别为3.6、2.9和2.6,晴天工况下集热系统和水源热泵运行模式在节能和供热性能方面有着显著优势。To reduce energy consumption during the heating period and achieve energy saving and emission reduction,an integrated heating system of solar energy-heat pump double tanks was designed to address the problem of reliance on coal-fired boilers for central heating in Northern China.Through experiments,the operating characteristics of the system under different weather conditions in the heating season were analyzed.The experimental results show that the system runs stably and can meet the heating requirements under different weather conditions in the heating season.Compared with sunny days and rainy and snowy conditions,the system can save 14.4%and 17.7%more energy on sunny days.On sunny,cloudy,sunny and rainy and snowy days,the average indoor temperature under working conditions is 18.3℃,17.2℃and 17℃,and the system COP is 3.6,2.9 and 2.6,respectively.The operation mode of the heat collection system and water source heat pump under sunny conditions has significant advantages in energy saving and heating performance.
