Is a fresh fan the same as an air conditioner, air purifier, and exhaust fan?

It's not the same, it's not a thing at all, the fresh air fan is a full-heat purification fresh air host, he is mainly ventilated, the outdoor air is purified and sent to each room, and then the indoor dirty air is discharged, and the energy is carried out when it is discharged, trying not to affect the indoor temperature, the air purifier belongs to the internal circulation, filtering particles and odors in the air, and cannot improve the indoor oxygen content, and the exhaust fan just discharges the indoor air

It's not the same. Fresh air systems and air purifiers are air quality purification devices; An air conditioner is an air temperature regulating device; Exhaust fans are to help with air circulation.

Let's focus on the difference between a fresh air system and an air purifier.

First of all, it is necessary to clarify the main difference between the two: air purifiers are indoor air circulation filtration; The fresh air system is a circulation filter of indoor and outdoor air.

Second, it's important to make it clear that we need filtered fresh air more than filtered air that is circulated repeatedly.

Now let me explain why you should choose fresh air over an air purifier

1. The air purifier needs to be used in a relatively closed space, and the use of open windows will reduce the effect;

2. The indoor air that is repeatedly filtered is indeed clean air, but the most obvious disadvantage is that the carbon dioxide concentration will continue to rise, making us feel stuffy and unable to breathe.

3. The most basic function of the fresh air fan (fresh air system) is ventilation - the introduction of outdoor fresh air; There are also filters that filter the outside air and bring it indoors – keeping the air clean.

Summary: If you really want to achieve a good indoor air environment, it is recommended to consider installing a negative ion fresh fan and choosing a negative ion purifier to assist. Small particle size negative ions themselves have the effects of smoke and dust removal, sterilization and disinfection, and are also beneficial to human health.

Fresh fans and air purifiers are both devices that can purify indoor air, so, do you know the difference between fresh fans and air purifiers? Next, PChouse will take you to take a look.

1. Appearance. Some fresh fans and air purifiers look very similar in appearance, however, there is a hole in the back of the new fan that is used to inhale outside air, while air purifiers do not have such holes.

2. Function. Some fresh air fans have an intelligent heating function that can heat the air sent into the room to a suitable temperature, while air purifiers do not have such a function.

3. Principle. The fresh fan is to suck the outdoor air in, purify and filter it and then send it into the room, and at the same time discharge the original indoor air out of the outside, which is a process of internal and external circulation. The air purifier is to inhale the indoor air into the body for filtration, and then discharge it to reduce the harmful substances in the room, and purify the air through internal circulation.

4、**。Generally, the fresh air system is tens of thousands of yuan (generally sold at **price, negotiate one**, all of them are included), it must be expensive, and the Xiaomi purifier is only 699, but the good purifier is also 10,000 yuan smaller.

5. In terms of noise and energy consumption, the purifier is better than fresh air. No matter how much fresh air is done, it will be a little bigger than the purifier. However, the fresh air can achieve an acceptable degree in noise reduction and does not affect normal rest.

<> "What are the differences between fresh fans and air purifiers:

1. The appearance is different.

In terms of appearance, although the two are somewhat similar, there are still certain differences, for example: there is a hole behind the new fan for inhaling outside air, while the air purifier does not have such a hole.

2. The functions are different.

From a functional point of view, many fresh fans have a heating function, which can heat the indoor air to the right temperature, while air purifiers do not have such a function.

3. The principle is different.

In principle, the fresh air fan has a large core and an independent air treatment system, which can filter the fresh air outside and transmit it into the room through the pipe, and at the same time discharge the indoor dirty and low oxygen content air outside. In addition, the new fan can also discharge the harmful imitation reed gas that is not released after the decoration to ensure that people's bodies are not damaged, and can also regulate the indoor humidity to avoid mold on furniture and clothes. The purifier can only adsorb, decompose or convert the harmful substances in the air in the indoor air, and then discharge the harmful substances in the room through internal circulation.

However, it also has an obvious flaw, that is, it only circulates indoors, and oxygen is always consumed.

4. **Different.

From the point of view of sales, the new fans are bought as a whole, and each set is about tens of thousands of yuan. The ** of the air purifier is relatively cheap, the ordinary one is about a few hundred yuan, and the good one is about 10,000 yuan.

5. Noise and energy consumption are different.

From the perspective of noise and energy consumption, the noise and energy consumption of the new fan are larger than those of the purifier, but they are within the controllable range and will not affect people's rest.

First, the fundamental working mode of the two is different. The air purifier is an internal circulation, which absorbs the indoor air and purifies it and then returns it to the room, and the pollution and bacteria that cannot be filtered will be returned to the room; Fresh air is the fresh air that circulates outside, which purifies and filters the outdoor air into the room, and the indoor dirty air is discharged outside.

Second, the purification area of the air purifier is limited, the area that the household air purifier on the general market can radiate is 10 to 20 square meters, and the air purification efficiency of the whole room is related to the distance of the equipment, the air filtration and purification effect near the general equipment is better, and the air filter and purification effect near the equipment will be worse, and even the room will have a filter dead end, and the fresh air equipment is generally installed at the top of the air supply outlet and the return air outlet, and the top or ground is sent back to the top, which can filter and replace the air of the whole house. It can also form a fresh wind lake, which makes the human body feel more comfortable.

In this case, the air purifier is used for a long time, there is no fresh air entering the room, the oxygen content of the air is reduced, the carbon dioxide increases, the human body will feel uncomfortable, and the air purifier will form secondary pollution, such as formaldehyde, benzene and other pollutants that are not easy to decompose, will remain in the purifier equipment, and will be sent into the room with the filtered air in the later stage, causing unnecessary secondary pollution; The fresh air will discharge the indoor dirty air outdoor, and the fresh air filtered outdoors will be sent indoors, so that the indoor air is not only pollution-free, but the air oxygen content can meet the national standard and the human body is more comfortable.

Summary. Hello, the main function of the fresh air system is indoor ventilation, with the function of air purification, which can introduce purified fresh air into the room when it is inconvenient to open the window; The main function of an air purifier is to purify indoor air, and there is no function of air exchange, which is the most fundamental difference between the two.

I hope mine is helpful to you, if you think mine is not bad, please give me a thumbs up, I wish you a happy life, goodbye!

What is the method of 100,000-level air purification?

What is the method of 100,000-level air purification?

It is used in the clean workshop of the factory.

It is used in the clean workshop of the factory.

Hello, the different designs of different air supply and return air systems in the clean room are the decisive factors that determine the different cleanliness levels of the clean room. Mode 1: The working principle of standard combination room air conditioning air conditioning air cabinet + air filtration system + clean room ventilation and insulation pipe + HEPA high-efficiency air supply outlet + clean room return air duct system, continuous circulation and replenishment of fresh air to send people to the clean room workshop to achieve the cleanliness required by the production environment.

Mode 2: The working principle of FFU industrial air purifier installed on the ceiling of the clean workshop directly to the clean room + return air column return air system + ceiling air conditioner cooling. This form is generally used in situations where the environmental cleanliness requirements are not very high, and the cost is relatively low.

The common fresh air system is a system that transports the outdoor air with high oxygen content to the room through the pipeline after filtration and other treatments, and at the same time discharges the indoor dirty and low oxygen content air out of the outdoors, aiming to create a healthy indoor environment with clean, fresh air and carefree breathing.

An air purifier is a product that can adsorb, decompose or transform various air pollutants and effectively improve air cleanliness.

The biggest difference between them is that the fresh air system filters the outdoor air and sends it to the room, which can solve the balance of indoor oxygen, while the air purifier can only filter the indoor air and cannot provide the oxygen that people need.

Of course, many of today's fresh air systems will include the effect of an air purifier.

It is recommended to use a fresh air system, which can deliver fresh and clean air to the room after absorbing harmful substances in the air after the outdoor air can be filtered for 24 hours. Regardless of indoor formaldehyde, toluene, xylene, and carbon dioxide exhaled by our human body, we need frequent ventilation. Our industrial waste, car exhaust, and dust in the air will enter the room through the air transmitted through the door, so we need a fresh air system for filtration and adsorption.

The air purifier can only circulate and purify the indoor air, which can purify the smoke and particulate matter, dust, etc. in the indoor air, but the room must be sealed, and we all know that the carbon dioxide exhaled by the human body cannot be purified by the purifier, so the air purifier can only solve the indoor air in a short time, and cannot completely improve the air quality of our living space.

Both the fresh air system and the air purifier are air purifying, but there is still a difference between the two.1 The air purifier has a short board or its own defect, that is, it can only purify the air indoors.

2 Air purifiers cannot solve indoor exhaust gases such as carbon dioxide, while fresh air can bring oxygen-rich fresh air into the room and expel the exhaust gases outside. Oxygen-rich fresh air is also important for the human body, but it is often overlooked.

3. The air purifier can only filter and adsorb the formaldehyde polluted by decoration, and formaldehyde is continuously released, and the fresh air system can continuously discharge the harmful gases of formaldehyde.

Therefore, the fresh air system is better than the air purifier in terms of function, but the fresh air system needs to be punched and installed, which is relatively inconvenient to move, while the air purifier is very convenient. Hope it helps.

I'll give you a simple example, and you'll definitely understand!

Ventilation fans and exhaust fans simply play the role of exhaust air, allowing air circulation, but cannot purify indoor air.

The fresh air system is to introduce the outdoor fresh air purification and filtration into the room, and at the same time discharge the indoor dirty air to the outside, which can form a convection of fresh and clean oxygen in the confined space, which not only purifies the air but also meets the fresh air required for human breathing.

Now there are many kinds of fresh air systems, and the quality of the effect is also uneven, the fresh air system is because there is no haze, it has entered our lives, but in fact, the purpose of the fresh air system is mainly to improve indoor air quality and improve our quality of life. In this regard, the fresh air system is much better than you think.

The fresh air system of Northumberberg in Germany can be ventilated 24 hours a day without opening the window, with a variety of installation methods, a variety of air supply methods, and is also equipped with a purification system and a full heat exchange system, which will purify the outdoor air layer by layer while ventilating to ensure the clean type of indoor air.

The fresh air system is called the "house breathing system", which is an open indoor air circulation system, which can effectively solve the problem of haze, more is the improvement of the indoor environment, through the exchange and purification of indoor air and outdoor air, and at the same time realize the external circulation and internal circulation, and solve the indoor particulate matter, formaldehyde, volatile organic compounds, bacteria, formaldehyde, carbon dioxide, oxygen and other comprehensive air problems. The ventilation fan and exhaust fan simply play the role of exhaust negative pressure, and do not have the role of air purification and exchange.

To put it simply, the fresh air system is to help you do a full range of air circulation, to ensure that all parts of the home can have fresh air in and exhaust gas discharge, need air intake, fan, exhaust three parts, while the ventilation fan only has the exhaust step, and can not ensure that the indoor air is fully circulated.

In addition, the current fresh air system is not only the role of air circulation, for example, the full exchanger, you can reduce energy loss while ventilating, for example, if you turn on the air conditioner in summer, the indoor temperature is 20 degrees, the outdoor temperature is 40 degrees, you want air circulation, the outdoor hot air enters, and the indoor cold air is discharged, which increases the load of your air conditioner, and the indoor temperature cannot be guaranteed. If the temperature of the full heat exchanger is replaced, the temperature of the incoming fresh air may be only 25 degrees, while the temperature of the exhaust air can be 35 degrees, thus reducing energy consumption.

1. Fresh air system, also known as fresh air ventilator, is a kind of air conditioning device. It generally consists of a main unit and a pipe, as well as an end.

The filter element is inside the main unit. It can filter dirty air, and there are two sets of pipes inside, one is to change out the indoor dirty air, and the other is to change the fresh air outside, but it must be exchanged internally, that is, you can't lose too much indoor air conditioning or heating.

Such a system can ensure that the introduction of fresh air and the discharge of dirty air can be met under the condition of meeting the needs of indoor temperature.

The feature is: to make the indoor environment more comfortable. The disadvantage is that it is expensive, and the internal filter element should be cleaned or replaced every once in a while, otherwise it will not be able to play the role of air exchange.

2. Ventilation fan generally refers to the fan used in the bathroom, kitchen, etc., but it has the function of non-return, that is, the wind can blow out, but the wind cannot be poured back.

3. The exhaust fan, in fact, is the same as the ventilation fan in the eyes of ordinary people, but the power of the exhaust fan is larger, such as restaurants, tunnels, residential roofs, supermarket roofs, etc.

Therefore, the difference can be distinguished according to its concept, and as for the selection, it depends on your own needs.
