Patent number: 10746439Abstract: A device to regulate the relative humidity level inside a CPV module, the device comprising a desiccant unit connected to the module via a duct, the module is also connectable to ambient atmosphere and the device comprises a switching mechanism that is actuated by a regulation unit, allowing a gas flow between the module and either the desiccant unit or ambient atmosphere. The air into the CPV module is let through a dehumidifier only when there is risk of condensation, which is determined from values of the air inside and/or outside the module by sensors sensing temperature and/or relative humidity and comparing these to thresholds or to the calculated dew temperature inside the module.Type: GrantFiled: February 12, 2014Date of Patent: August 18, 2020Assignee: Saint-Augustin Canada Electric Inc.Inventors: Andreas Gombert, Jakob Stor, Cecile Taliercio
