Which places must install fresh air systems - the necessity of installing fresh air systems in public places

Nowadays, young people have more choices on weekends to go to the movies and go shopping. Many people feel very comfortable when they go to shopping malls. Compared with the old department stores before, they are more comfortable, but from the outside, shopping malls are not separate Open the ventilation windows, so where does this comfortable feeling come from? In the same way, many large office buildings and hotels are the same. Now more and more public places will choose to install fresh air systems. In addition to the credit of central air conditioning, the credit of fresh air systems cannot be ignored.

What is a fresh air system?

The principle of the fresh air system is very simple, that is, it can continuously discharge the indoor dirty air in a timely manner 24 hours a day, and at the same time introduce outdoor fresh air, and effectively control the air volume, increase energy recovery, and create a healthy and good indoor high-quality living environment. , to create a healthy and energy-saving residential environmental protection system for residents. The fresh air system is an independent air treatment system composed of a fresh air ventilator and pipeline accessories. The fresh air ventilator filters and purifies the outdoor fresh air and transports it indoors through the pipeline. The fresh air system is based on the use of special equipment to supply fresh air to the room on one side of the airtight room, and then from the other side to be discharged to the outside from the special equipment to form a "fresh air flow field", so as to meet the needs of indoor fresh air ventilation.

Why do public places such as shopping malls and gyms need to install fresh air systems?

According to the survey, the air pollution in public places is dozens of times higher than that in residential buildings. There are densely populated areas, and various odors, sweat, and odors are flooded together. Coupled with the use of central air conditioners, the building structure is relatively It is airtight and the air cannot be circulated. It is conceivable how bad the air quality is. Take the gym as an example, because the gym space is relatively closed, the air is not ventilated, dirty, and the oxygen content is low, especially people need sufficient oxygen to maintain uniform breathing during exercise. Hypoxia will not only reduce the metabolic capacity of people's bodies and brains, but also cause dizziness, chest tightness, fatigue, emotional ups and downs and other uncomfortable symptoms in an environment with poor air quality for a long time, which will greatly affect physical health and induce various diseases. can also cause cancer. Only with the constant supply of fresh air can people breathe sufficient oxygen in public places and feel happy. Because of the continuous replacement of fresh air, bad air such as various odors and germs in the room can be quickly discharged outside! The places with severe air pollution are not only gymnasiums, but also schools, leisure places, restaurants, shopping malls, etc. They are all places with many people, bacteria, and abnormally polluted indoor air. If you want to work, study and work in these indoor environments for a long time. In life, children and adults with poor immunity and low immunity will feel mentally ill, unwell, and even sick. At this time, you may choose to install a fresh air system to ventilate and exchange air for the indoor environment. It replaces the indoor and outdoor air 24 hours a day, discharges the indoor dirty air in real time and injects the filtered oxygen-enriched air into the outdoor.

The necessity of installing fresh air system in public places

1. Poor ventilation: Generally, many small and medium-sized public places (such as office buildings, hotels, guesthouses, saunas, etc.) have relatively small lighting and ventilation areas, and the natural ventilation capacity is relatively poor, especially in some of the independent rooms without windows. No natural ventilation. Mechanical air supply and exhaust are its important means of ventilation. 2. Large flow of people and many pollution sources: This kind of place also has the common characteristics of large flow of people and many pollution sources (such as office appliances, smoking, water vapor, etc.). There will be different degrees of chest tightness, astringent eyes, dizziness and other symptoms; and after the place is corroded by smoke, water vapor, odor, etc. for a long time, the odor will be difficult to eliminate. 3. The ventilation equipment is backward: Now most of these places are equipped with ventilation equipment such as exhaust fans, but they often lack professional ventilation design, it is difficult to form a reasonable fresh air, exhaust flow direction and achieve a reasonable ventilation volume, and the ventilation effect is often not good. ideal. The quality of indoor air is closely related to our health. In addition to solving the problem of lack of ventilation, removing moisture, and removing the decoration pollution that may exist after decoration, the fresh air system can also avoid long-term public places such as shopping malls and office buildings. Erosion such as smoke, water vapor, and peculiar smell guarantees long-term use in public places, and also provides consumers with a healthy and comfortable consumption environment. The installation of fresh air system in office buildings can also improve the work efficiency of white-collar workers
