Indoor space oxygen and humidity control device

Abstract

The invention relates to an indoor space oxygen and humidity control device and belongs to the field of new energy technology application and air circulation technology application. The device comprises a sensor module, a control module, a system power supply module and PEM electrolytic cells. The sensor module comprises oxygen sensors and a temperature-humidity sensor. The output ends of the oxygen sensors are connected with a single chip microcomputer and used for transmitting current oxygen concentration signals. The temperature-humidity sensor is used for acquiring the temperature-humidityinformation in the environment and transmitting the temperature-humidity information to the single chip microcomputer. The control module comprises a PWM-to-voltage module and the single chip microcomputer. The single chip microcomputer receives the oxygen concentration signals from the oxygen sensors, calculates the oxygen generation rate required by the environment and controls the output voltage of the PWM-to-voltage module in a PD self-tuning manner. According to the indoor space oxygen and humidity control device, the electrolytic voltage of a proton exchange membrane fuel cell is precisely controlled, the oxygen concentration and humidity in a room or a sealed scene are controlled, and the proportion of outer circulation of an air conditioner system is reduced, so that the purposesof energy saving and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the fields of electrolyzed water technology and air circulation technology, and relates to a control device for oxygen and humidity in an indoor space. Background technique [0002] The most important way to maintain the oxygen concentration of indoor air is to maintain good ventilation, but it is also restricted by many conditions, such as: foggy weather, rainy days, etc. are not suitable for opening windows; on the other hand, it is cold and dry in the north, and there are few people Windows will be opened for ventilation. This will lead to a decrease in indoor oxygen content and a sharp increase in carbon dioxide concentration, which will have a great impact on human health. At present, the mid-to-high-end air-conditioning products on the market all have a ventilation function, that is, the outdoor fresh air is sucked into the room through the ventilation pipe to keep the indoor air fresh, which consumes a lot of power and ...
