Central ventilation system and fresh air humidification control method

Abstract

The invention relates to the technical field of fresh air, in particular to a central ventilation system and a fresh air humidification control method, and solves the problem of weak humidification effect in a traditional central ventilation system with a humidification device. The central ventilation system comprises an air supply subsystem and a humidification subsystem; the humidification subsystem comprises a dehumidification film set, and a vacuum pump connected with the dehumidification film set; the vacuum pump is used for vacuumizing the dehumidification film set to form negative pressure in the dehumidification film set; the humidification subsystem further comprises a humidification unit; and the humidification unit communicates with the dehumidification film set for feeding water in the dehumidification film set indoors to humidify indoor air. Through arrangement of the humidification unit, the humidification subsystem can quickly and effectively feed the water generated inthe dehumidification set film after pressurization through a compressor, so that the humidification effect of the humidification film set is guaranteed, and the humidification efficiency of the central ventilation system is improved.

Description

technical field [0001] The invention relates to the technical field of fresh air, in particular to a fresh air system and a fresh air humidification control method. Background technique [0002] With the development of society and the improvement of living standards, people's requirements for air quality are getting higher and higher, and the fresh air system has become more and more popular. The fresh air system is a device that can help indoor ventilation. It introduces outdoor fresh air into the room after treatment, and discharges indoor polluted air to the outside, thereby ensuring the circulation of indoor air and ensuring that the room always has fresh air. Air, to meet the needs of the human body. In addition, the fresh air system has a certain air purification and filtration function, which can continuously deliver fresh air to the room. However, the function of the current fresh air system is only to replace and purify the air in the room, which also causes the d...
