Description

An indoor fresh air purification and ventilation device

technical field

The utility model relates to the field of fresh air systems, in particular to an indoor fresh air purification and ventilation device.

Background technique

In recent years, smog has occurred frequently throughout eastern and central China, and the air quality has shown a downward trend, causing more and more indoor air quality problems. Indoor decoration materials, daily chemical products, combustion products and human activities can also cause the deterioration of indoor air quality. In addition, due to the unreasonable design of many buildings, many residential buildings, shopping malls, hotels, and office spaces have poor ventilation, which has caused many indoor air quality problems and brought inconvenience to people's lives. Indoor pollutants are mainly divided into inhalable particulate matter, volatile organic pollutants, bacteria and viruses and other microorganisms, which can cause sick building syndrome, respiratory diseases, bronchitis, pneumonia, leukemia, cancer and other diseases. Literature data show that the excess deaths caused by diseases caused by indoor pollution in my country can reach 111,000 people every year, the excess number of emergency visits reaches 4.3 million, and the excess number of outpatient visits reaches 220,000. Various examples and data show that indoor pollution control is urgent.

At present, the air purifiers on the market mainly use filtration technology, negative ion technology, activated carbon adsorption technology and electrostatic dust removal technology. Outdoor fresh air, after a long time, will easily lead to insufficient indoor oxygen content and increased _CO2 content, causing people's discomfort, and has little effect on long-term volatilized pollutants such as formaldehyde in decoration materials. Based on this, fresh air system devices began to appear on the market. The fresh air system can filter and sterilize the outdoor air, send fresh air into the room, and at the same time exhaust the indoor air. On the one hand, it can reduce the indoor _CO2 content and increase oxygen; on the other hand, it can purify the air entering the room and improve the indoor air quality. However, the fresh air systems currently on the market mainly have the following problems: (1) Many wall-mounted fresh air systems cannot effectively discharge indoor dirty air; (2) Some fresh air systems can only introduce fresh air from the outside, and cannot perform indoor circulation purification (3) The current fresh air system is basically not equipped with an air duct that directly leads outdoor air without filtering (suitable for buildings with good outdoor air quality and poor ventilation).
