Photovoltaic module dehumidifier

摘要

Dehumidifier for photovoltaic modules, of a series of photovoltaic concentration modules, formed by a common air inlet and outlet access that communicates all the modules, and which passes through a bed of moisture absorbing material, having an electrical self-adjusted resistance (15) installed therein. The circuit is completed with a solenoid valve (13), a flow switch (19), a non-return valve (12); a pressure switch (16) and a timer relay (20). The process is based on pressure differences existing within the photovoltaic modules throughout the day, and consists of two steps: drying air by passing through the bed of absorbent material before entering into the photovoltaic modules and the regeneration of the drying system, which can be automatically or manually by connecting a compressor or fan.

主权项

1. A dehumidifier for photovoltaic modules, which maintains a humidity level inside a series of photovoltaic concentration modules below allowable limits, wherein the dehumidifier comprises a common pneumatic circuit that connects all the photovoltaic modules to each other, and which is connected to a drying system through a common inlet; the drying system having a circuit comprising a filter, inside of which is a moisture absorbing material and a self-adjusted resistance, as well as a solenoid valve, a flow switch, a non-return valve, a pressure switch and a timer relay; wherein the dehumidifier also has an auxiliary inlet.
