Indoor air refreshing method

Abstract

The invention discloses an indoor air refreshing method. The indoor air refreshing method comprises a fresh air device mounted outdoors, a fan, an indoor air output channel and a fresh air input channel, wherein the indoor air output channel and the fresh air input channel communicate with the indoor space; and an air purifying device is arranged at an indoor end of the indoor air output channel. With the adoption of the technical scheme, the indoor air refreshing method has the effects that: outdoor fresh oxygen gas is obtained while indoor air is purified in a circulating mode, so that indoor air is clean, and oxygen gas consumed by human body metabolism is supplemented, and therefore, the air refreshing effect is achieved, health of people is facilitated, and working and learning efficiency is favorably improved; and mechanical work of the indoor air refreshing method is completed outdoors, so that the indoor is free of mechanical noises.

Description

technical field [0001] The invention relates to the field of indoor air freshening, and is characterized in that fresh oxygen is obtained from the outside while the indoor air is circulated and purified, and there is no mechanical noise in the room. Background technique [0002] According to the statistics of relevant state departments, the number of lung cancer patients in my country has doubled every 10 to 15 years in the past half century. According to the results of the third survey on the causes of death among residents in my country, the mortality rate of lung cancer has increased by 465% in the past 30 years, and it has now become the malignant tumor with the highest mortality rate. The rapid increase in the incidence of lung cancer has an important relationship with the increase in air pollution. Controlling air pollution is a systematic project accompanying social development, not a problem that can be solved in a short time. In fact, most people live indoors more...

AI Technical Summary

Problems solved by technology

[0003] At present, the social satisfaction of products related to improving indoor air quality in the market is low, and the main problems are: first, the ventilation volume during air purification is small, and indoor air cannot form a good cycle purification

Because the air flow is subjected to greater resistance during the air purification process, increasing the ventilation volume also increases the noise. Air purification and noise pollution are problems that are difficult to solve with current technology.

The second is that air purification and indoor oxygen cannot be integrated, and the oxygen consumed by indoor human metabolism cannot be replenished in time.
