Floor type direct blowing fresh air ventilator

Abstract

The invention provides a floor type direct blowing fresh air ventilator. The fresh air ventilator comprises a cabinet body, an air-inlet section, an exchange section and an air-outlet section. The air-inlet section is arranged at the lower portion of the cabinet body and comprises a fresh air inlet, a filtering device and an indoor exhaust air inlet, the fresh air inlet is arranged at the right lower portion of the rear end surface of the cabinet body, the filtering device is installed in the middle of the lower part of the cabinet body, and the indoor exhaust air inlet is arranged at the lower portion of the left end surface of the cabinet body; the exchange section is positioned in the middle inside the cabinet body and comprises a heat exchanger and a draught fan, the draught fan is installed at the right side inside the cabinet body, and the heat exchanger is arranged at the left side of the draught fan; the air-outlet section is positioned on the upper portion inside the cabinet body and comprises an air supply outlet and an efficient filter screen, and the air supply outlet is arranged at the upper portion of the front end surface of the cabinet body. According to the floor type direct blowing fresh air ventilator, a direct blowing structure and a four-level filtering and purification method are adopted, mounting is simple and convenient, the noise is low, the multi-angle air-out and efficient adsorption of harmful gases can be achieved, the fresh air ventilator is applicable in transition seasons, the adjustment is intelligent, and energy consumption is reduced.

Description

technical field [0001] The invention relates to a floor-type direct-supply fresh air fan. Background technique [0002] With the acceleration of the industrial process, the social economy is highly developed and brings a series of environmental pollution at the same time. Among them, air pollution has become more and more serious in recent years. In autumn and winter, most cities in my country and the vast northern regions are shrouded in smog. The smog contains various fine particles and toxic substances that are harmful to the human body. There are more than 20 kinds, including acids, alkalis, salts, amines, phenols, etc., as well as dust, pollen, mites, influenza virus, tubercle bacillus, pneumococcus, etc. Since the diameter of fine powdery floating particles in the haze is generally less than 0.01 micron, they can directly enter the bronchi and lungs through the respiratory system, causing respiratory diseases, cerebrovascular diseases, nasal cavity inflammation, etc. ...
