HC New Air Network In recent years, with the attention of all sectors of society on indoor air pollution, solving indoor air pollution has become one of the important measures in recent years in China. Since the birth of the fresh air system, it has aroused widespread concern around the world. At present, many countries have promulgated and implemented various new wind system policies and regulations, and the market for fresh air systems has gradually matured and formalized. The so-called fresh air system introduces outdoor fresh air through physical principles on the premise of not opening windows for 24 hours, and discharges indoor turbid air containing harmful substances such as formaldehyde, benzene, ammonia, etc., so that the outdoor and indoor air are fully exchanged to ensure indoors. A microcirculation system with plenty of fresh air.
Fresh air system purchase considerations
Choose the right fresh air function: single row, single delivery, full heat recovery, remove PM2.5
If the new house has not been renovated, and the height and structure permit, it is recommended to install a full heat exchange fresh air system, the ventilation and ventilation volume is stable, the indoor temperature and humidity change is small; with the use of air conditioning, long-term operation saves costs. At the same time, you can purchase fresh air equipment that removes PM2.5 function to avoid the influence of smog weather and create a safe home environment.
If the house has been renovated, consider installing a split fresh air system or a ductless fresh air system. The split fresh air can be installed step by step, and can be installed horizontally before loading other places.
First, the determination of the amount of air
Generally, the air volume of the home is determined according to the number of air exchanges. Usually, the number of home air changes is 0.5-1 times/hour. Then, the air volume of the building is calculated, and the area of ​​the fresh air area required by the building is multiplied to complete the surface height, and finally multiplied by each. The number of hours of air exchange is the amount of fresh air required by the family. For example: a building with a building area of ​​100m2 and a height of 2.8m, the required fresh air volume is 100.
Multiply by 2.8 times the number of air changes. This is the main calculation method for the family's new wind.
Second, the air purification level
Nowadays, the fresh air system is no longer the era of only one heat exchanger. Nowadays, the level of air filtration by the fresh air system is becoming more and more important. It is more and more important to choose a new wind with PM2.5 filtering effect. Buying fresh air is Need to ask how much the filter level of the new wind can be achieved, how the effect is, and so on.
Third, about the number of air changes
Generally, the bedroom goes 0.5-1 times. The area with lots of people like the living room, dining room, and chess room is bigger, ensuring a better fresh air effect. Moreover, fresh air equipment generally has different gear switches, which can be adjusted as needed.
Fourth, the installation position of the fresh air host
The fresh air main engine is generally installed on the ceiling of the kitchen and the bathroom, so that it does not occupy extra space and is concealed, which does not affect the interior beauty and reduces the noise impact. Split-type machines are generally installed in the lower part of the window sill, which is easy to maintain and does not affect the curtains.
Five, the arrangement of the exhaust vent
Many sellers of fresh air systems now have to install only one air inlet in the bedroom to save installation costs, or to install a total air outlet in the living room. This is not impossible, but there is a precondition that the bedroom is not particularly good, and the air can flow through the gap to the living room, which can form air flow. Small rooms generally have no major problems. If the area is large, it is best to ensure that each room has an air inlet, an air outlet, the air inlet is located at the innermost corner of the bedroom, and the air is placed at the door to ensure the first time. The freshest air.
Sixth, installation method:
There are five theoretical installation methods, the top to the ground, the top to the top, the top to the top, and the top to the wall. Why are there five theoretically? Because the top-loading top-back installation method is not used in the home-installed fresh air, it is generally used in the operating room of the hospital. The reason why the home is not recommended is that the dust in the home is relatively large, and the way of installing it back will cause dust. After a long period of accumulation, the dust in the return air pipe will be accumulated more and more, affecting the ventilation effect. Generally, more is used to send the top back and the top to return, and now the wall is slowly coming back. Up, and the top-receiving top-back has lower requirements on the machine, and the ground-receiving top return and the wall-receiving top return have higher requirements on the performance of the machine, so when you buy the machine, you can also ask if the machine can do the delivery. The installation method of the top return is also recommended for the installation method of the top return, which is based on the diagonal flow of the air field and the physical quality of the air component.
At present, there are many different types of fresh air systems in the market, which are different in terms of brand, performance, price and quality. The advantages and disadvantages of different products are also different, and each has its own advantages and disadvantages. Consumers should choose according to their needs to ensure the new style of choice. The system is economical, healthy and environmentally friendly, achieving the desired ventilation and ventilation effect.
