Embodiment Construction

[0012] As shown in the accompanying drawings, a solar-powered indoor ventilation device of the present invention includes a photovoltaic module, a DC / DC unit, a battery drive circuit, a ventilation fan, an oxygen concentration detection unit, and a controller. The module converts solar energy into electric energy, and then converts it into the voltage required by the controller through the DC / DC unit. The controller detects the indoor oxygen concentration through the oxygen concentration detection unit. When the indoor oxygen concentration reaches the set value, the ventilation fan is turned off. At this time, the DC / DC unit The output electric energy charges the battery, and the controller has the overcharge protection function for the battery. If the battery is not fully charged, it will continue to charge, and if the battery is fully charged, it will stop charging; when the indoor oxygen concentration is lower than the set value, the ventilation fan will be turned on, and the...

Abstract

The invention discloses a solar energy powered indoor air exchange device. The air exchange device comprises a photovoltaic module, a direct current (DC) / DC unit, a storage battery drive circuit, an air exchange fan, an oxygen concentration detection unit and a controller; the photovoltaic module is connected with the DC / DC unit; an output interface of the DC / DC unit is connected with an input interface of the drive circuit; an output interface of the drive circuit is connected with the air exchange fan; a storage battery is connected in parallel between the DC / DC unit and the drive circuit; the oxygen concentration detection unit is connected with the controller; and the controller is connected with the DC / DC unit, the storage battery and the drive circuit respectively. The solar energy powered indoor air exchange device can ensure effective ventilation when the oxygen concentration in a room is too low and guarantee the health of a human body, and also can prevent energy waste and the wearing of the air exchange fan.

Description

technical field [0001] The invention relates to the application field of solar energy, in particular to an indoor ventilation device powered by solar energy. Background technique [0002] With the development of society, people's living conditions are constantly improving, and home decoration is popularized. In order to save energy, the room is usually in a closed state. If it is in this environment for a long time, the oxygen concentration will be too low and the indoor pollutant concentration will be too high. , thereby affecting people's health. In addition, some offices, shopping malls and other places have fewer doors and windows, and the ventilation effect is poor, but there are many people gathered, and the oxygen concentration is too low, which cannot meet the normal mutual needs of people. In order to solve these problems, many families consider placing plants indoors to absorb carbon dioxide and increase indoor oxygen levels. But this oxygen is a by-product of th...
