Description

A vertical cabinet type combined fresh air ventilator

Technical Field

The utility model relates to the technical field of ventilators, and more specifically, to a vertical cabinet-type combined fresh air ventilator.

Background Art

Traditional civilian fresh air ventilation equipment is mostly an integrated design with relatively single functions, such as traditional full heat exchange equipment and one-way flow ventilation equipment. Some of this type of equipment also integrates purification, dehumidification, humidification, etc., but they are all integrated designs and cannot be separated;

At present, when the fresh air ventilator is working, it is necessary to introduce air from the air inlet for dust removal and humidification, so that the exhausted air can meet the corresponding ventilation requirements. Among them, when removing dust from the introduced air, the existing technology mainly uses a dust removal net to block the entry of dust, and the blocked dust will adhere to the dust removal net. As time accumulates, the dust removal net will be blocked by dust, which leads to a significant reduction in the amount of air entering, thereby resulting in a decrease in the air volume at the air outlet of the fresh air ventilator; this requires cleaning the dust removal net, but when used in some areas with serious air dust pollution, the dust removal net will be blocked in a very short time, which greatly increases the frequency of cleaning the dust removal net, thereby increasing the labor of manual cleaning.
