摘　　要：针对太阳能供暖系统早上集热器启动后,蓄热水箱升温慢导致太阳能供暖不及时的缺点,研发了一种即热式蓄热水箱。水箱工程应用的试验研究结果表明:在太阳能-空气源热泵复合地板辐射供暖系统中采用这种即热式蓄热水箱,早上集热器启动后,地暖供水温度可快速升温至设计值,达到即热的效果,从而减少辅助热源的使用;室外气温是影响集热器启动时间和地暖供水温升速率的重要因素;在晴天和多云天气集热器运行期间,系统可以依靠太阳能而不使用辅助热源为房间供暖,维持室温在15~22 ℃.In order to overcome the shortcoming of slow heating by solar energy of the hot water storage tank in solar heating system in the morning, the instantaneous hot water storage tank was designed. The experimental results of water tank engineering application show that the low-temperature floor radiant heating water can be quickly heated to appropriate temperature for heating after the collector is opened in the morning when the instantaneous hot water storage tank is used in the solar-air source heat pump composite radiant floor heating system, which can reduce the heat pump service time. The opening time of collector and heating rate of the heating water are affected by the outdoor air temperature;During operation of collector in sunny and cloudy daytime, the system can rely on solar energy without using an auxiliary heat source to maintain the room temperature at 15~22 ℃,which is fit for living.
