Indoor and outdoor air exchange and intelligent purification system

Abstract

The invention provides an indoor and outdoor air exchange and intelligent purification system. The indoor and outdoor air exchange and intelligent purification system comprises a shell, wherein an air inlet cavity and an air outlet cavity are arranged in the shell, the air inlet cavity and the air outlet cavity are communicated through an air inlet channel, an air inlet is formed in the air inlet cavity, an air outlet is formed in the air outlet cavity, an exhaust channel is further arranged in the shell, the two ends of the exhaust channel are provided with an inner exhaust outlet and an outer exhaust outlet respectively, an air inlet fan is arranged at the air outlet, an exhaust fan is arranged at the outer exhaust outlet, a turbofan is arranged at the end, located at the air inlet cavity, of the air inlet channel, and the air inlet, the air outlet, the inner exhaust outlet and the outer exhaust outlet are respectively provided with a filter screen. The indoor and outdoor air exchange and intelligent purification system has two air inlet modes, namely the negative pressure air inlet mode and the positive pressure air inlet mode; as a result, the indoor air quality can be guaranteed, the air inlet quantity is effectively improved, and indoor air is kept fresh.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an intelligent system for realizing indoor and outdoor air exchange. Background technique [0002] With the deteriorating environment, air pollution has become a problem that people are more and more concerned about, especially in my country, where the air pollution is particularly serious, and PM2.5 seriously exceeds the standard, which will cause adverse effects on people's health. In this case, people also become more and more concerned about how to purify the air. Various air purification devices have also emerged at the historic moment, but most of the air purification devices on the market are indoor types, that is to say, they can only purify the air in the room, and the air in the room cannot be circulated. The new air added from the outside will still contain harmful substances of smog and dust at the beginning, and people in the room will inevitably come into contact wi...

Problems solved by technology

Various air purification devices have emerged as the times require, but most of the air purification devices currently on the market are indoor types, that is to say, they can only purify the indoor air, and the indoor air cannot circulate.

The new air added from the outside will still contain harmful substances of smog and dust at the beginning, and people in the room will inevitably come into contact with this air. Therefore, the effect of this air purification device on air purification is not thorough, and the air purification The harmful gas filtered out by the filter also stays indoors, which will also have adverse effects on people's health

[0003] In order to facilitate indoor air circulation, people sometimes install window ventilators indoors. This kind of window ventilator is installed at a high place, and the risk factor of people switching up and down is high, but the ventilation area is limited when it is installed at a low place. Most of the type ventilators have no power, the filter layer has great resistance to natural wind, the air volume entering the room is limited, and the air purification effect is poor, and the indoor air quality index is relatively high
