【摘要】 介绍了一种新型的太阳能-空气源热泵直接地板辐射采暖系统,把空气源热泵、太阳能系统和直接地板辐射采暖结合起来,在充分利用太阳能的同时,保证供暖系统的高效稳定运行。在甘肃兰州地区搭建采暖实验房进行实验研究,对实验结果分析表明,系统在晴天、阴天和雪天三种典型天气状况下运行的平均COP分别为3.4、2.6、3.1。室外温度8℃时达到最大COP值4.2,系统稳定运行后,室内温度在20℃左右轻微波动,满足冬季室内供暖需求和舒适性要求。更多还原

【Abstract】 A new type of solar- air source heat pump direct radiant floor heating systems,air source heat pumps,solar energy systems and direct radiant floor heating combined were introducesd,making full use of solar energy at the same time to ensure the efficient and stable operation of the heating system. The heating experiment room was built in Lanzhou,Gansu Province to experiment research,the experimental results showed that the average COP of the system run in sunny,cloudy and snowy were 3. 4,2. 6,3. 1,when the outdoor temperature is 8 ℃maximum COP value 4. 2,When the system run steady,the room temperature slightly fluctuating around 20 ℃,meeting the need of human body on thermal comfort.更多还原
