Fresh air blower and fresh air generation method

Abstract

The invention provides a fresh air ventilator and a fresh air generation method. The fresh air ventilator comprises a shell component. The shell component comprises a box body and a mounting and connecting piece; an accommodating space is formed by an internal space of the box body; the accommodating space is divided into multiple functional areas by the mounting and connecting piece, and the functional areas are mutually connected or partially communicate to one another; the multiple functional areas comprise an air inlet area, a filtration area, an air blower mounting area, a sterilization area, and an air outlet area, wherein the air inlet area communicates with an outer space of the box body through an air inlet formed in the box body; a filtration device is arranged in the filtrationarea; an air blower is arranged in the air blower mounting area; a sterilization device is arranged in the sterilization area; and the air outlet area communicates with the outer space of the box bodythrough an air outlet formed in the box body. The fresh air ventilator and the fresh air generation method disclosed by the invention have the advantages that through detection of indoor air pollution extents and indoor and outdoor temperature difference, an air door of mixed air can be automatically regulated, and the effects of stabilizing the indoor temperature and delaying the service life ofa filter screen can be achieved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a fresh air blower and a method for generating fresh air. Background technique [0002] Existing fresh air purification equipment generally uses a fan to inhale air from the outside and discharge clean air into the room after being filtered by a filter. Among them, the one-way micro-positive pressure fresh air fan is widely used because it does not need to lay pipes for easy installation. In recent years, due to the general attention of the public to PM2.5, quite a few fresh air fans have added the function of automatically adjusting the fan speed according to the indoor PM2.5 content, and some fresh air fans have additional heating functions for use in cold weather, and very few models are equipped with Air disinfection function. [0003] However, there are many problems in practical application. Firstly, the volume of fresh air fans with large air volume is relatively large. Fr...

Problems solved by technology

[0003] However, there are many problems in practical application. Firstly, the volume of fresh air fans with large air volume is relatively large. Fresh air fans with an air volume of 500 cubic meters per hour exceed the volume of air-conditioning indoor cabinets by a lot. Secondly, there is the problem of noise. Under large air volume, the noise problem is An important factor that affects the user experience. Third, most fresh air fans cannot choose between indoor and outdoor air intake, and do not have the function of mixing air. When the temperature difference between indoor and outdoor is large or the indoor air quality is already good, they still The use of outdoor air intake will result in uncomfortable indoor ambient temperature and unnecessary loss of filter media

Fourth, the fresh air fan with automatic adjustment according to air quality detection, because the detection sensor is located on the body, cannot reflect the air quality of the user's real activity area, this measurement mechanism has defects, which affects the accuracy of automatic adjustment

Fifth, most of the fresh air fans equipped with heating devices do not have a constant temperature function, and there are problems of uneven heating and high energy consumption

Sixth, for fresh air fans equipped with disinfection equipment, due to the high wind speed in the channel, the actual disinfection time is very short, and the expected disinfection effect cannot be achieved
