[0042] The centralized fresh air system refers to that the fresh air machine set with deep dehumidification function in the machine room cools and dehumidifies the outdoor high-temperature and high-humidity natural air to low-temperature and low-humidity fresh air, and sends the fresh air into the designated area, such as the indoor of the residential user, through the heat-insulated iron pipe to replace the original air in the indoor, so as to achieve the purpose of dehumidifying the indoor. Since the rubber sealing strip, sealing gasket and other components on the iron pipe may be aged after long-term use, the rubber sealing strip, sealing gasket and other components may fail, thereby causing the iron pipe to leak air. Therefore, when the centralized fresh air system is designed, the air leakage coefficient of the iron pipe is usually considered, and the air volume of the centralized fresh air system is expanded by 1.2-1.3 times to prevent the rated air volume from not being reached due to air leakage in the later stage of operation of the centralized fresh air system. Therefore, in the early stage of operation of the centralized fresh air system, there is a large amount of excess fresh air reserved due to the consideration of the air leakage factor in the later stage of operation. However, in the traditional centralized fresh air system, the excess fresh air is not fully utilized, resulting in waste of high-grade resources. Meanwhile, in the traditional centralized fresh air system, a plurality of dehumidifiers need to be configured to alleviate the basement humidity return phenomenon, increase the operation cost, and further cause unnecessary waste of resources. The fresh air dehumidification system provided in the embodiments of the present application can transmit the excess fresh air in the early stage of operation of the fresh air dehumidification system to the humid basement, so as to achieve the purpose of dehumidifying the basement while reducing the dehumidification cost of the basement and avoiding waste of resources.

The detection unit can include a humidity sensor, which is a device that uses sensor principles to sense the humidity level in the air, and can output digital signals or analog signals to determine the indoor humidity. Optionally, the indoor humidity can also be determined by the relative humidity calculation method. Relative humidity is the ratio of water vapor content in the air to the saturated water vapor content at the current temperature, usually expressed as a percentage, which can be calculated using a thermometer and a dew point table.

[0063] Specifically, when the remaining fresh air is transmitted to the basement through the basement air supply pipe 6 and the basement air supply port 8, the exhaust unit in the basement adjusts the number of exhaust fans in operation in the exhaust unit 9 according to the remaining fresh air flowing through the basement air supply pipe 6, to balance the air intake and exhaust in the basement.
