并网型光伏空调制冷研究

为研究并网型光伏空调的制冷特性,对甘肃省自然能源研究所一并网型太阳能光伏空调系统进行了合理地优化设计,考虑房间冷负荷、光伏阵列装机容量、光伏阵列倾角等对太阳能光伏空调的影响,实测了甘肃省兰州市夏季光伏空调的发电量和用电量,并进行了电力平衡分析。结果表明:1.5~2.0kW的光伏阵列在需要制冷的夏季可以提供15.3m2的办公室制冷所需的电量。另外,并网型太阳能光伏空调的环境和经济效益显著。光伏空调的成本回收时间约为6.2年。因此,随着人们环境保护意识的增强和光伏组件价格的下降,并网型太阳能光伏空调将会成为未来光伏技术应用发展的一个重要方向。

Grid-connected Photovoltaic Air Conditioner Refrigeration Research

In order to research the refrigeration characteristic of grid-connected photovoltaic air condition-er,conduct the reasonable optimization design on the grid-connected photovoltaic air conditioner system on the roof of office room in the gate house of Gansu Natural Energy Research Institute,the influences of room cooling load,photovoltaic array installed capacity and photovoltaic array inclination degree on the photovoltaic air conditioner have been considered;measure the power generating capacity and power con-sumption of photovoltaic air conditioner in the summer in Gansu Lanzhou and conduct the power balance analysis.Results show that the photovoltaic array of 1.5~2.0 kW can provide the electric capacity meet the refrigeration requirement of office room of 15.3 square meter in summer.In addition,the environmental and economic benefits of grid-connected photovoltaic air conditioner are remarkable.The cost recovery period of photovoltaic air conditioner is about 6.2 years.Therefore,along with the increase of environmental protec-tion awareness and decrease of photovoltaic module price,the grid-connected photovoltaic air conditioner is about to become a direction of future connected photovoltaic technique application and development.
