摘要

建立无填料热源塔热泵系统实验平台，研究不同进风位置、喷嘴位置、室外空气干球温度、相对湿度、风量、溶液入口温度下无填料热源塔吸热效率的变化规律。结果表明：进风位置和喷嘴位置对热源塔的吸热效率会产生影响，下喷式无填料热源塔吸热效率高于上喷式无填料热源塔；干球温度与吸热效率无明显相关性，但干球温度升高，热源塔从空气中吸收的总热量增加；相对湿度和风量升高，吸热效率提高；溶液入口温度升高，热源塔的吸热效率明显提高。与其他参数相比，溶液入口温度对热源塔的吸热效率影响最大。

Abstract

An experimental system was established for non-packed heat source tower system. The heat absorption efficiency of the heat source tower was studied under the different air inlet positions

spray nozzle positions

air dry-bulb temperatures

relative humidity

air flow rates

and solution inlet temperatures. The results show that the position of air inlet and spray nozzle has obvious impact on heat absorption efficiency. The heat absorption efficiency of down-spray heat source tower is better than that of the up-spray tower. There was no significant correlation between heat absorption efficiency and dry-bulb temperature

while with the air dry-bulb temperature increases the total amount of heat absorbed from the air increases. The heat absorption efficiency increases with the air flow rate and relative humidity increase. With the inlet solution temperature increasing

the heat absorption efficiency is obviously improved. Compared with other parameters

the inlet solution temperature has the greatest impact on heat absorption efficiency.
