摘要
本实验在室内用碘钨灯代替太阳辐射,通过改变碘钨灯与太阳能冷管之间的距离来调节太阳辐射强度。整个周期太阳辐射强度范围为400~1000W/m^2,室内环境温度范围在19~25℃,湿度维持在40%左右。太阳能冷管吸附床脱附过程中的最高温度为120℃;吸附过程中温度下降至20℃左右;太阳能冷管一个周期内单根冷管的制冷量为160k J,制冷系数约为0.15。太阳能冷管可以有效地利用太阳能制冷,是一种对环境友好、没有温室效应和臭氧破坏势的制冷方式,该研究具有潜在的应用价值,具有节能环保的特点。
This experiment use iodine tungsten lamp instead of solar radiationin indoor,adjusting the intensity of solar radiation by changing the distance between the iodine tungsten lamp and solar cooling tube. In the whole cycle,the radiation intensity range of the sun is 400 ~ 1000 W / m^2,the ambient temperature is 19 - 25℃ and the humidity remains at about 40%. The highest temperature of the adsorption bed is 120 ℃ in the desorptionprocess and The temperature of the adsorption bed falls to about 20 ℃. The refrigerating capacity of single solar cooling tube is 160 k J and the COP is 0. 15. It is a way of refrigeration which caneffectively utilize solar energy. It is friendly to the environment with its GWPODP = 0. The study has the characteristics of environmental protection and energy saving with potential value of application.
