First, the working principle of fresh air system
Fresh air system is imported from abroad, and most families in Europe and America will install fresh air system, whose function is to ventilate and keep the indoor air fresh at all times (long-term lack of ventilation will lead to the growth of many bacteria and insufficient oxygen concentration, which is harmful to the health). However, when the fresh air system arrived in China, because of the serious air pollution in China, the fresh air system in China was improved, and besides the ventilation function, the air purification function was added.
The working principle of Haoting fresh air system: Haoting fresh air system is divided into two parts: the main machine is installed in the living room or balcony, which is responsible for purifying outdoor air and introducing it into the room. At the same time, install a breathing Bao 'an in the bedroom window to exhaust the dirty indoor air outside, and then use the air pressure difference between the living room and the bedroom to make fresh air flow from the living room to the bedroom, so as to keep the indoor air fresh and clean at all times.
Second, fresh air system compared with window ventilation:
1. Do not open the window, enjoy fresh air for 24 hours, and ensure adequate ventilation (change indoor air 0.5-0.7 times per hour);
2. Avoid noise, dust, mosquitoes and smog caused by window ventilation to make the room quieter and more comfortable;
3. Continuous ventilation can effectively remove indoor odor and moisture and prevent the growth of bacteria and mold;
4. In winter and summer, the fresh air system with total heat exchanger can save energy to a great extent and create a comfortable indoor environment.
5. The fresh air system filters the outdoor air and inputs it indoors, and at the same time discharges the indoor dirty air.
Third, compared with the air purifier, the fresh air system
1. Solved the problem of indoor carbon dioxide exceeding the standard caused by long-term opening of the air purifier;
2. It solves the indoor problem that people are still in unventilated and continuously polluted due to the low efficiency of the air purifier;
3. Ozone pollution caused by some air purifier purification technologies such as electrostatic technology and negative ion plasma is avoided;
4. Solved the problem of temperature and humidity and the loss of purification effect caused by the need to open the window for ventilation after turning on the purifier for a period of time.
