Is the fresh air system an air conditioner? What is the difference between a fresh air system and an

No, air conditioners are used to regulate the temperature, while fresh fans are used to improve indoor air. It is necessary to buy a new fan, especially in a small room where the air is not suitable for circulation, you can go to Jingdong***.

Buy a Philips fresh air fan, so that the ventilation is not cold in winter and not hot in summer.

Air conditioning fresh air system: one of the three major air circulation systems of air conditioning.

A fresh air system is not an air conditioner.

We may often hear the saying that a new fan can cool and heat. This is a complete misunderstanding, and the "total heat exchanger" in the fresh air system is used to reduce the heat loss of indoor and outdoor air convection.

And all this is premised on the fact that the temperature in the room itself is low enough that this can only be achieved by air conditioning. The fresh air system can only play a role in maintaining the indoor temperature.

At present, there are already machines on the market that integrate air conditioning and fresh air, such as air environment machines, which can also be disinfected, sterilized, and humidified.

1. The working principle of the fresh air system and the air conditioner.

1. Fresh air system: The working principle of the fresh air system is to improve the indoor air quality, discharge the indoor turbid air outdoor, and the outdoor fresh air enters the room through the filter box;

2. Air conditioning: The working principle of air conditioning is to improve indoor heating and cooling, and to cool or heat the air in a closed room so that human beings can achieve comfort.

Second, the respective roles of the fresh air system and the air conditioner.

Fresh air system: The fresh air system is a circulation process of indoor and outdoor air to ensure the freshness and health of indoor air;

Air conditioner: The biggest and most obvious role of air conditioning is to change the temperature change of indoor air.

The fresh air system and the air conditioner are complementary.

Although the operation of the fresh air system and the air conditioner are very different in terms of system operation, the role of the two in the home is complementary. As people's living standards are getting higher and higher, the pursuit of comfort in life is also higher, air conditioning can only refrigerate and heat to keep the human body at a comfortable temperature, but can not ensure the freshness of the air.

Summary: You can't blindly judge the quality of the two by the difference between the fresh air system and the air conditioner, and deny a certain product, depending on the specific needs of the owner, the focus is on adjusting the indoor temperature or ensuring the indoor air quality to choose the fresh air system and air conditioner.

1. The role is different.

The fresh air system is to improve the indoor air quality, the indoor turbid air is discharged from the outside, and the outdoor fresh air enters the room through the filter box.

Air conditioning is to improve indoor heating and cooling, cooling or heating the air in a closed room so that human beings can achieve comfort.

2. Different ways.

Air conditioners regulate the indoor temperature by cooling and heating.

The fresh air system uses the circulation of indoor and outdoor air to ensure indoor air quality.

Advantages of the fresh air system.

1. You can enjoy the fresh air of nature without opening the window;

2. Avoid "air-conditioning disease";

3. Avoid moldy indoor furniture and clothing;

4. Remove the harmful gases that are released for a long time after indoor decoration, which is beneficial to human health;

5. Indoor temperature and humidity to save heating costs;

6. Effectively eliminate all kinds of bacteria and viruses in the room;

7. Super silent;

8. Reduce indoor carbon dioxide concentration;

9. Dustproof.

To put it simply, the fresh air system solves the problem of indoor air quality and oxygen content, and the air conditioner solves the problem of indoor air temperature.

Air conditioning is an internal circulation system, with cooling or heating effect, the indoor air temperature is regulated and controlled, in summer, the room temperature can be reduced to 18 25, in winter, the room temperature can be raised to 22 28, to achieve a comfortable state of the human body. In general, the frequency of using air conditioners in summer will increase greatly, and air conditioners are a state of internal circulation and do not have the ability to bring in fresh air.

There are also some ** air conditioners with fresh air function, its "fresh air function" is to pump part of the outdoor air through the air inlet, after some simple filtration, through the compressor that comes with the machine will cool or heat the air to the room, and the return air outlet will suck the indoor dirty air back for indoor dead circulation purification.

The fresh air system is an external circulation system, which introduces fresh air from the outdoors and sends it into the room through multi-layer filtration, so as to filter out harmful car exhaust, particulate matter, dust and other harmful gases in the outdoors. Through 24-hour uninterrupted delivery of fresh and clean air, indoor pollutants such as formaldehyde, TVOC and so on are continuously diluted.

At the same time, indoor pollutants such as carbon dioxide, formaldehyde and other harmful gases are discharged to the outdoors. For example, some professional brands such as Bruscher have developed new fans that can achieve internal and external circulation at the same time, which can completely replace air purifiers.

Air conditioning brings us comfortable and cool air, and at the same time, after blowing the air conditioner for a long time, the body will be prone to dizziness, fatigue, dryness, decreased immunity and other symptoms, which is called "air conditioning disease" in modern medicine. In addition, the intersection of cold and warm air is more frequent in summer, and the temperature fluctuates greatly, so if you don't pay attention to it, you are prone to colds, coughs and other upper respiratory diseases.

No matter what the season, we need to strengthen the supply of fresh air indoors, and at the same time purify the indoor air to effectively ensure the health of our bodies when we stay indoors for a long time. In summer, the air conditioner is turned on for a long time, the indoor air is turbid, the carbon dioxide solubility increases, and the window is urgently needed to be opened for ventilation, but the outdoor hot air will accelerate the rise of indoor temperature and increase the energy consumption of the indoor air conditioner with your opening of the window! The fresh air system brings in fresh air from the outside, which is filtered into the room through multiple layers, and at the same time pollutes the indoor air such as:

Carbon dioxide, formaldehyde and other harmful gases are discharged to the outdoors, and the energy exchange core inside the fresh air system keeps the cold temperature of the indoor air conditioner while constantly exchanging indoor and outdoor air, so that indoor energy consumption is not lost, the air cleanliness is consistent, and healthy air is guaranteed.

Therefore, it is the most effective way to control indoor air pollution and provide fresh and clean air and fresh air system, and air conditioning is the best shortcut to keep you cool quickly.

Difference Between Fresh Air System and Air Conditioner:

In layman's terms: the fresh air system is for indoor and outdoor ventilation, and the air conditioner is for indoor heating and cooling, and there is no conflict between the two. Some air conditioners also have "fresh air", but this is "fake fresh air", because it uses positive pressure air supply, and the indoor pressure reaches a certain level, which is higher than the outdoor pressure and the static pressure of the fan, and the wind will never go indoors.

The air received by the wall-mounted air conditioner comes from the air conditioner itself, forming a closed circulation system between the room and the air conditioner;

Some air conditioners with a slight fresh air are difficult to continue to supply air in areas where fresh air has formed a positive pressure indoors;

Bacteria multiply at the exhaust outlet, especially in winter, the temperature of the air conditioning outlet is a hotbed of bacteria;

It cannot achieve the purpose of sufficient exchange of indoor and outdoor air, and ** is higher than ordinary air conditioning.

Now there is a first-class air conditioning intelligent ventilation system in the market, in fact, the system is also fooling, its principle is the joint installation of air conditioning and fresh air system, in the final analysis, it is the combination of fresh air system and air conditioning, not air conditioning with fresh air system, according to this combination, such as Panasonic's fresh air conditioning solution. For this type, consumers can choose the product by themselves, rather than buying it as a package.

Essence: **Air conditioning intelligent ventilation system = **air conditioning + fresh air system.

For home users, the use of negative pressure fresh air system can achieve a very good ventilation effect, now people generally believe that the more high-end hot fresh air system, in fact, more suitable for office buildings, shopping malls, restaurants and other places with a large number of people, its air exchange is large, energy loss is more. The family's energy loss is not much, if you "take care of it", the installation of a hot fresh air system, whether it is the early investment or the later operation cost is three to four times that of the negative pressure fresh air system.

So the best combinations are the following:

Fresh air system + air conditioning.

Fresh air system + underfloor heating.

Fresh air system + heat pump air conditioning.

Fresh air system is a must-choose, just for health! Many people attribute many of today's diseases to environmental pollution, yes, more precisely, indoor environmental pollution, no matter how much you eat and drink, only a few times a day, but we breathe all the time, and people spend more than 85% of their time indoors.

There is an essential difference between the two in terms of function, the air conditioner is used to regulate the indoor temperature, and the fresh air system is used to improve the indoor air quality.

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 constant convection of fresh and clean oxygen in the confined space, which not only purifies the air but also meets the fresh oxygen required for human breathing. In particular, the third generation of negative ion fresh air came out, and at the same time, it also released small particle size negative ions, which themselves have the effect of purifying the air, and at the same time have a special effect on the human body for recuperation and health care. The best technology for negative ion fresh air in China is the Shenghuan fresh air jointly developed by Tsinghua University, and the small particle size negative ion technology led by Professor Lin Jinming, a doctoral supervisor of Tsinghua University.

The functions of the air conditioner and the fresh air system are different, the air conditioner is responsible for indoor temperature control, and the fresh air system is responsible for air quality. They are two separate systems, and the pipes are not the same. The duct of fresh air is thicker and not easy to bend, and the duct of the air conditioner is thinner, but the two can be compatible, and it is best to carry out it in the front section of the decoration, and the air outlets of the two can be arranged side by side.

In the air conditioner, the real sense of fresh air is to replace the air circulating for a long time in the closed-loop system, the amount of fresh air is generally about 15% of the total air supply, and the fresh air is inhaled from the outdoor fresh air outside the closed-loop system, if the amount is too large, it is not energy-saving. The "new" air is for the "old" air that has been circulating in the system for a long time.

The essence of the fresh air system is to use a fan to circulate air. Air conditioning is refrigerated by a compressor, and then a fan is used to deliver cold air to achieve a cooling effect.

The fresh air system is more energy-saving and environmentally friendly than the air conditioner.

The main function of the fresh air system is to meet the needs of indoor air quality (human hygiene needs);

The main function of air conditioning is to solve the indoor air temperature and humidity requirements.

This kind of feature is hype.

And the original air conditioner, not much difference.

It's just a gimmick, and it doesn't make sense to filter the air.

First of all, it can be determined that in terms of function, the air conditioning and fresh air system are not duplicated. **Air conditioning is regulated by cooling and heating.

The indoor temperature is reduced, and the fresh air system uses the circulation of indoor and outdoor air to ensure indoor air quality.

**How air conditioning works).

Second, in terms of improving living comfort, the two are complementary. **Air conditioner uses the function of cooling and heating to make the human body in a relatively comfortable position.

At the right temperature, the fresh air system can ensure the freshness of the indoor air. In layman's terms: in summer, the doors and windows are closed 24 hours a day.

At the same time, the indoor temperature can be kept at about 25 degrees, and the air will be clean and refreshing.

Finally, the combination of the two reduces the damage rate of the machine and balances the energy consumption. A simple example is that the outside temperature is relatively high.

If the room is entered through the fresh air system "total heat exchanger", the temperature of the fresh air will be lowered (the principle will be explained in detail below), so that the room will be reduced.

The air conditioner does not need to consume more energy to cool down.

First, the reference is different.

1. Fresh air system: It is an independent air handling system composed of air supply system and exhaust system.

2. Air conditioning: equipment that regulates and controls the temperature, humidity, flow rate and other parameters of the ambient air in the building or structure by manual means.

Second, the principle is different.

1. Fresh air system: purify the outdoor air through the fresh fan and introduce it into the room, and discharge the indoor air through the pipe; The ductless fresh air system is composed of fresh air fans, which also purify the outdoor air and introduce it into the room.

2. Air conditioning: The compressor compresses the gaseous refrigerant into a gaseous refrigerant with high temperature and high pressure, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes a liquid refrigerant at room temperature and high pressure.

Third, the role is different.

1. Fresh air system: use outdoor fresh air to update the indoor air polluted due to living and living process, so as to keep the cleanliness of indoor air to a certain minimum standard.

2. Air conditioning: with heating and refrigeration functions, it is suitable for hot areas in summer and cold in winter.

Dear, I'm glad to answer your <>

The difference between the fresh air system and the air conditioner is that the functions are different: the most basic function of the fresh air system is to ventilate, discharge the turbid indoor air, introduce fresh outdoor air, and realize the circulation of indoor and outdoor air, that is, the external circulation of air, and the function of air conditioning is to refrigerate and heat, without these ventilation functions. The amount of ventilation is different:

The ventilation volume of the fresh air system is larger than that of the air conditioner, and the ventilation volume cannot be controlled, which cannot meet the indoor ventilation standard of residential buildings proposed by the World Health Organization. <>

The advantages and disadvantages of the fresh air system are: 1. Provide fresh air. You can enjoy the fresh air without opening the windows, making the human body healthier. 2. Expel harmful gases in the room.

For example, formaldehyde, cigarette smell, bacteria, viruses and other harmful gases, so as to avoid the harm of toxic gases for children and the elderly at home. 3. Anti-mildew and odor removal. The indoor is sometimes humid, which affects human health, and the polluted air is discharged in time to prevent mildew and bacteria, which is conducive to prolonging the service life of household items.

4. Reduce noise pollution. There is no need to endure the distraction caused by opening windows, making the room quieter and more comfortable. 5. Dustproof.

Avoid opening windows to bring a lot of dust, effectively filter the outdoor air, and ensure that the air entering the room is clean. 6. Safe and convenient. In order to avoid the hidden dangers of wealth and personal safety caused by opening windows.

Even if there is no one at home, it will be automatically ventilated <>
