摘要
设计了一种太阳能温室滴灌系统,该系统主要由供电和供水两部分组成:供电部分采用太阳能电池阵列,将太阳能转换成直流电驱动水泵工作;供水部分采用电动直流隔膜泵。系统中太阳能电池无需逆变器,直接驱动水泵工作,降低了系统成本;水泵体积小、重量轻、使用寿命长,在太阳辐照度低的情况下也能实现供水。该系统工作效率高、成本低,有利于节约水资源和充分利用太阳能。
A kind of solar powered drip irrigation system in greenhouse is designed in this paper. It mainly composed of two parts, namely power supply part and water supply part. The power supply part adopts solar array, which changes solar energy into direct current to drive pump. The water supply part uses electric direct current diaphragm pump. In the system, the solar array drives the pump directly and the DC-AC converter is unnecessary, which reduces the system cost. The pump is small, light, and has a long life -time. It also can work even if the solar radiation intensity is lower. The system has high efficiency and low cost, so it is beneficial to conserve water resources and make full use of solar energy.
