Abstract

We have studied the dynamics of air humidity in the interior of a concentrator photovoltaic (CPV) module equipped with air-drying device filled with moisture-absorbing material based on silica gel. A new design of the air-drying device was developed for preventing the deposition of condensate onto the surfaces of a Fresnel lens, solar cell, and CPV module. Under unfavorable ambient conditions (relative humidity up to 95%), this device allowed to reduce the inner humidity to 25–55% at cyclic temperature variation within 15–45°C and to increase the dew point deficit up to 10–25°C.

带干燥装置的聚光光伏模块中空气湿度的动态

摘要

我们研究了配备有风干装置的聚光光伏（CPV）模块内部的空气湿度动力学，该风干装置装有基于硅胶的吸湿材料。为了防止冷凝水沉积到菲涅耳透镜，太阳能电池和CPV组件的表面，开发了一种新的风干设备设计。在不利的环境条件下（相对湿度最高为95％），该设备允许在15–45°C的循环温度变化下将内部湿度降低至25–55％，并将露点缺陷增加至10–25°C 。
