摘要
为增强蜂蜜成熟过程中水分的蒸发效果,设计出一种新型的太阳能蜂箱并对其性能进行初步测试。在25、30、35℃的条件下进行蜂蜜水分蒸发的稳态实验,并在自然条件下完成太阳能蜂箱与普通蜂箱动态对比实验。稳态实验结果表明随着实验温度的升高,蜂蜜水分蒸发速率和蒸发量逐渐增大。以2018年3月28日07:00~17:00的实验为例,集热器的热效率处于0.061~0.406之间,全天的平均热效率为0.251。太阳能蜂箱内空气平均流速为0.60 m/s,水分蒸发总量为1.94 g,而普通蜂箱内空气平均流速仅为0.13 m/s,水蒸发总量为1.20 g,蜂蜜水分的蒸发效果提升度最大达到89.53%。初步测试结果为后期在蜂场进一步的研究提供参考依据。
In order to improve the thermal environment in the beehive and enhance the moisture evaporation effect of honey,a novel solar energy powered beehive was designed and explored in this paper.The experiment of honey moisture evaporation at 25,30 and 35℃was carried out,and the dynamic comparison experiment of the novel solar energy powered beehive and ordinary beehive.The experimental results showed that the moisture evaporation effect increased sequentially at 25,30 and 35℃.Take 07:00-17:00 on March 28,2018 as an example,the thermal efficiency of the collector is between0.061 and 0.406.The average thermal efficiency is 0.251;the average velocity in the solar energy powered beehive is 0.60 m/s and the total moisture evaporation of honey is 1.94 g;the average velocity in the traditional beehive is 0.13 m/s and the total moisture evaporation of honey is only 1.20 g.The maximum level of effect improvement was 89.53%.Preliminary summary and analysis of the results of the experiment study will provide a preparation for further research.
