摘要

为了保护蜜蜂生命、提高产量和蜂蜜质量,蜂箱对热量的要求非常高。电价上涨可能会减少蜂蜜生产的净利润。因此,本研究旨在改造一种利用光伏板运行的蜂箱加温系统,以降低蜜蜂死亡率,改善蜂群活动,提高蜂蜜的强度和质量。该取暖系统基于珀尔帖(Peltier)模块理论,利用太阳能电池运行。珀尔帖模块使用直流电,只需极少的维护,冷热交界处均采用陶瓷板。该研究包括分别配备 1、2、3 和 4 个珀尔帖模块的供暖系统。结果表明,光伏板输出功率逐渐增加,上午 11 点达到 250 瓦的峰值,下午 3 点急剧下降到 115 瓦的最低值。光伏效率各不相同,上午 9 点达到 13.9%,上午 11 点降至 13.6%,下午 3 点达到峰值 15.7%。使用 1、2、3 和 4 个 Peltier 组件,占用的时间分别增加了 4、8、11 和 13 个时间段。而在传统的加温方法下,占用框数从 4 个减少到 3 个。使用 1、2、3 和 4 个 Peltier 模块的蜂蜜产量分别为 4.1、5.1、5.8 和 6.4 千克,而非加温系统的蜂蜜产量为 2.8 千克。使用 4 个 Peltier 模块的改良加温系统的净利润比传统加温系统高 95.8%。

Modification of a Beehive Warming System Based Upon Peltier Module
The heat requirements for beehive are significant to preserve bee life, increase yield and obtain high honey quality. The increased electricity prices may diminish the honey production net profit. So, this study aims to modify a beehive warming system which operates using a PV panel to reduce bee mortality, improve honeybee colony activity, and enhance the strength and quality of honey. The warming system used based upon the Peltier module theory, operated with solar cells. The Peltier module works with DC power, requiring minimal maintenance and includes ceramic plates for both the hot and cold junctions. The study includes a warming system provided with 1, 2, 3, and 4 Peltier modules, respectively. The results indicate a gradual increase in PV panel output power, peaking at 250 Watts by 11 am and sharply declining to a minimum of 115 Watts by 3 pm. PV efficiency varies, reaching 13.9% at 9 am, dropping to 13.6% by 11 am, and peaking at 15.7% at 3 pm. The occupied frames increased by 4, 8, 11, and 13 frames using 1, 2, 3, and 4 Peltier modules, respectively. While, it decreased from 4 to 3 occupied frames under the traditional warming method. The honey production was 4.1, 5.1, 5.8, and 6.4 kg using 1, 2, 3, and 4 Peltier modules, respectively, opposite 2.8 kg for the non-warming system. The net profit of the modified warming system with 4 Peltier modules was 95.8% higher than that of the traditional warming system.
