Buy fresh air system can not only look at the brand, there are many types of fresh air system, according to different home decoration needs and use area can choose different fresh air system, then, how should we choose the right fresh air system for yourself?

First of all, let's understand what is a negative pressure unidirectional flow fresh air system, a positive pressure fresh air system, and a two-way flow fresh air system.

The negative pressure unidirectional flow fresh air system is formed by the fresh air fan after working in the room, and the fresh air is introduced into the room by the pressure difference between indoor and outdoor air, and then sucked into the fresh air fan, and discharged from the fresh fan outdoors. The positive pressure fresh air system is to blow the outdoor fresh air into the room after the fresh fan works, form positive pressure indoors, and squeeze out by the pressure difference between indoor and outdoor at the gap between doors and windows. The two-way flow fresh air system is introduced by the fresh air from the outdoor supply fan, and then sent to the indoor need area through the air duct, and the old air is also returned to the exhaust fan through the pipeline and discharged from the exhaust fan in a centralized manner.

However, how do we choose a fresh air system? It can be based on the following aspects:

1. Fresh air volume. The fresh air volume required by the building is generally calculated according to the "building volume" and "indoor capacity", and the fresh air system is selected with the larger value. For example, if there is a building with an area of 30 and a floor height of 3 meters, it is calculated according to the formula "building volume = room area x net floor height x number of air changes" (the national standard air change times are, then the fresh air volume required by the building is 45m hp; If a 30m building is permanently inhabited by 3 people, the fresh air volume required by each person is 30m hp under normal circumstances, and the fresh air volume required by the building is 90m hp; In order to ensure sufficient fresh air, the building needs to select a fresh air system according to the standard of 90m hp fresh air volume.

2. Filtration effect. The HEPA standard filter achieves the filtration efficiency for micron substances. The higher the filter level, the stronger the filtration effect.

However, the dust holding capacity of the HEPA filter is insufficient and the service life is limited, so it is recommended to choose a fresh air purification system with a rich combination of filters and a HEPA level higher than H13.

3. Noise. Generally speaking, the noise of the fresh air purification system is proportional to the air volume, the larger the air volume, the louder the noise, so when purchasing fresh air, we need to find a balance between the air volume and noise, and the maximum noise is recommended not to exceed 45 decibels when purchasing the fresh air system, otherwise it will have an impact on daily life rest.

4. Heat exchange. In order to solve the problem of indoor temperature difference caused by air displacement to the human body and energy loss, the energy in the exhaust gas can be discharged indoors through the full heat exchanger, so as to heat or cool the air introduced into the outdoors, balance the indoor temperature difference, ensure a comfortable temperature environment, and reduce the energy loss caused by air replacement.

As an innovator in the industry, Dream Maker stands out among similar products with its simple and ultimate German design style, excellent workmanship, superior performance and quality, and is recognized as the most high-end air purification product in the industry in the world. The design of the control panel on the front of the fuselage is quite simple, but it is quite functional, and this small panel not only has a rich selection of functions, but also provides indoor air information at all times, such as pollutants, temperature, temperature, etc. In terms of air intake, the Dream Maker Constant Oxygen Purifier is more like a fresh air system, where the air enters the machine from the lower part and passes through the pre-filter.

The high-efficiency HEPA filter is equipped with the ESP dust collection device we mentioned before to adsorb and purify the particulate dust in the air. This reduces indoor concentrations.

Well-known brands of fresh air system: Honeywell, Panasonic, Bruscher, Edis, Sender, Yuanda, Huandu, etc.

Upstairs, it is the Thomas brand of To, the garbage of the fresh air products, I am here to confuse the public, non-state authority data, are all deceptive.

The recommended brands upstairs are all foreign brands, the price is high, and some of the power output is poor from the domestic environment, and it is inconvenient to use. In recent years, the development of new fans of domestic brands is also good, and representative brands such as Ningbo Lanerson can be understood, and they are expected to adopt.

American Blanc Blanc, French Lanche, American Thomas, German Scheiheim, Japanese Panasonic and so on.

Mainly look at the quality, noise, after-sales.

As far as I know, there is no authoritative organization in China that has made a "top ten ranking" of the fresh air system. At present, the top ten brands and top ten rankings are basically ranked by the private sector, and the credibility of the rankings without standards is still relatively low.

The main reason to understand the ranking is to buy fresh air, and to buy fresh air mainly depends on four points:

Filtering effect. Generally, the purpose of buying fresh air is to purify the indoor air, so the filtration effect must be the first consideration.

Noise. If it is a home installation, this must be taken into account, as too much noise can affect sleep and rest.

Full heat** effect. Some fresh air systems will have this function, mainly energy-saving (if you don't understand, you can ask Du Niang).

The size and history of the enterprise. The scale of the enterprise is large, the history is long, the enterprise is relatively stable, if you choose a small business, there will be a risk of bankruptcy, if you go bankrupt, there will be no place to find repairs. Personally, I know that companies like Panasonic (Japan), Westinghouse (USA), and Honeywell are relatively large companies with a long history.

Manual typing, I hope the landlord adopts, thank you)

I really don't know anyone on this list, except for the following.

Panasonic, General Air, Yuanda, Blang, Dream Maker, Edison, Lansher, Honeywell, Zefeng, Daikin.

Panasonic, Byrana, General Air, Yuanda, Edis, Sender, Daikin, Dream Maker, Zefeng, Lanshe.

Domestic brands are rare, the quality is not good and slowly eliminated, Huandu, Yuanda, Hall Fresh Wind, Ruilang, Azure Wind, etc., more professional, fair, foreign not necessarily good, especially in Japan, are black businessmen, have been fooled, everyone pay attention.

According to the sales volume and consumer feedback of the online network and the China fresh air industry network, the top ten fresh air turbine brands currently operating in China are ranked, and the following brands are on the list: 1Prinson fresh air fan.

Summary. The top ten rankings of fresh air systems in 2020 are Honeywell, Edda Air, Daikin, Aldes, Disney, Zehnder, Broan, Airdow, Blauberg, and Yuanda.

What are the brands of fresh air equipment? Which of the top 10 brands of fresh air is better?

The top ten rankings of fresh air systems in 2020 are Honeywell, Edda Air, Daikin, Aldes, Disney, Zehnder, Broan, Airdow, Blauberg, and Yuanda.

These brands are all good, Honeywell Daikin, etc. are good.

From the three aspects of brand credibility, product quality and service, the top ten fresh air brands in the real estate industry are:

Panasonic: It is a "veteran" in the new wind industry and has a long history.

Honeywell: Insist on air purification for many years, an old American manufacturing company.

Glasco: The "dark horse" of the real estate fresh air industry, the fresh air brand of the famous listed company Kinlong.

Byrun: The brand of ventilated socks from North America is in a leading position in the North American market.

Yuanda: It is good at electrostatic filtration.

Daikin: A Japanese brand with a history of 80 years, like Yuanda, fresh air uses electrostatic filtration.

Sender: a ventilation brand from Switzerland.

LANSHER: Air purification expert from Europe.

Thomas is round: a rising star in the fresh air industry.

Midea: The fresh air layout of the old brand.

Top 10 brands of fresh air system: Princeson, Panasonic, Yuanda, Honeywell, Edison, Daikin, Brown, Bole, Langshi, Sender. Among the brands with good air conditioning effect, I recommend Princeson, Yuanda, and Panasonic.

1. Princeson.

Prinzon is known in the industry for its durability and stable performance, the fuselage is integrally formed by environmentally friendly alloy, and the fans used have strict requirements for both material selection and production quality testing, which can ensure the stability of performance in the long-term air exchange treatment, not only durable, but also always maintain ultra-quiet operation, reduce mechanical loss, and have an air exchange volume of 180-5000m3 h, which can meet the needs of different scenarios.

2. Yuanda. Yuanda fresh air system can be said to be the mainstay of the domestic brand of fresh air, and it is more prominent in the dust and haze removal. Yuanda fresh air fan filtration and filtration particulate matter is mainly composed of three modules: coarse efficiency + electrostatic + high efficiency; The later water washing refers to the coarse effect and static electricity, and its high-efficiency filter section also needs to be replaced, and the main force of removal is the high-efficiency filter section.

3. Panasonic. Panasonic fresh air system is safe, reliable, technologically advanced, easy to operate and maintain, Panasonic full heat exchange is the biggest selling point, unique among global brands. Panasonic total heat exchanger can continuously supply fresh air 24 hours a day, and can be used as usual in cold winters.

Answer: Good evening, I received your question here, and I recommend you the brand Panasonic, which does have a very high coverage rate of self-developed high-efficiency heat exchange core in our country.

Question: What I want to know about is the overhead heated fresh air system.

Answer: From the perspective of common products and reasonable charging standards, a new house with an area of 100 square meters requires about 12,000-15,000 yuan to install a fresh air system, and about 9,000-12,000 yuan to install a wall-mounted fresh air system.

Advantage 1: It can replace indoor air.

Keep the indoor air fresh and healthy at all times. Moreover, the new fan can work 24 hours a day, and you can enjoy fresh air at any time, and the air quality is much better than opening windows for ventilation.

Question: Which brand is more cost-effective for the kind installed on the roof of the shed?

Preferably the one with heating and humidification.

This brand of Panasonic is indeed quite good.

Question: I saw that the "Panasonic" advertised on the Internet are all wall-mounted, is any of Panasonic installed on the roof of the shed?

The top 10 brands of fresh air system are: Yuanda fresh air system, Panasonic fresh air system, Hall fresh air system, Yadu fresh air system, Maidilon fresh air system, Braun fresh air system, Honeywell fresh air system, Brown fresh air system, Bole fresh air system, and Langshi fresh air system. Personally, I recommend Yuanda fresh air system.

Yuanda fresh air system is a well-known brand in China, and the product has "large air volume, high quality and low price". Founded in 2005 and headquartered in Changsha, Yuanda Fresh Air System has more than 300 air experience halls and specialty stores all over the country, covering more than 30 countries, and has been recommended by celebrities and foreign dignitaries from all over the world, and is a globally recognized leader in air quality technology.

The Yuanda fresh air system can filter 99% and kill the bacteria attached to the particles at the same time. The small fresh air fans on the market are basically hoisting design, and only equipped with coarse filtration, and basically have no filtration effect. It is feasible to use it in Europe, Australia and other areas with good outdoor air quality, but if it is used in China, such fresh fans will become a source of indoor air pollution.

Only the new fan equipped with coarse efficiency, electrostatic precipitator and high-efficiency combined composite filtration technology can meet the requirements of efficient dust removal and sterilization.

The surface-mounted open body design makes it easy to clean the filter unit. The fresh air fan constantly treats the dirty outdoor air and requires frequent maintenance of the filtration or dust removal device. If the filter can only be replaced and cannot be cleaned, the cost of use is very high.

Therefore, in addition to the fuselage should be designed to be open and easy to maintain, the dust removal device can be cleaned repeatedly.

Extremely low operating power consumption to ensure low operating costs and no noise, the new fan is always open all year round. For example, the power distribution of the fan is large, on the one hand, the equipment is noisy, and on the other hand, the operating cost is high. Under the premise of not sacrificing the effect of dust removal and sterilization, the power consumption of the equipment must be processed to less than 1W m3h before it has the possibility of civil use.

Intelligent control, frequency conversion function to meet the needs of regulation, original low-resistance technology and mature electrostatic precipitator, sterilization technology of Yuanda Thermal, completely solve the problem of indoor air pollution, while the operation and maintenance cost is only 7 yuan m3 years, and the operating room investment is 5-10 times lower than the same level of purification. People can afford to buy and use, making it possible for health to enter the family.
