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

The fresh air system is used in villas, hotels, large apartments and occasions where air conditioning is installed and ventilation is needed for fresh air. Full heat exchanger product introduction: refers to a kind of fresh air and exhaust air ventilation equipment containing a full heat exchange core.

Its working principle is: when the product is working, when the indoor exhaust air and fresh air flow through the heat exchanger core in a positive cross mode, due to the temperature difference and vapor partial pressure difference between the air flow on both sides of the air flow separator, the heat and mass transfer phenomenon is presented when the two air flows through the separator, causing the whole heat exchange process. When running in summer, the fresh air obtains cooling capacity from the exhaust air of the air conditioner, which lowers the temperature, and at the same time is dried by the air conditioner, so that the moisture content of the fresh air is reduced; During winter operation, the fresh air receives heat from the exhaust air of the air-conditioned room, and the temperature rises, and at the same time it is humidified by the exhaust air of the air-conditioned room.

In this way, through the full heat exchange process of the heat exchange core, the fresh air is removed from the air conditioning exhaust air and the energy equipment is mainly composed of the chassis, the full heat exchange core and the exhaust fan.

Air purifiers only purify indoor air such as dusting, sterilization, and filtration, unlike fresh air systems, which completely purify fresh air and move it into the room and remove dirty air.

In addition to the ventilation function, the fresh air system also has the functions of deodorization, dust removal, dehumidification and room temperature adjustment. 1. **Fresh air system: ventilation function provides people with the fresh air they need to breathe, discharges the polluted air, and keeps the room comfortable and smooth 24 hours a day.

2. **Fresh air system: deodorization function The ventilation fan can quickly discharge the uncomfortable odor caused by various reasons and create a comfortable environment. 3. **Fresh air system:

Dust removal function There are many bacteria that are invisible to the naked eye in the dust floating in the air, so it is necessary to drive away dust in the home and workplace and create a comfortable environment. 4. **Fresh air system: moisture removal function The moisture in the living room not only comes from the bathroom, but also the human body and the gas appliance will release water, and now the building is better sealed, and it is easy to have the problem of mildew condensation and rotting of the bed and wall, so the ventilation fan is often used to remove the moisture in the room, which can keep the room and people comfortable and healthy.

5. **Fresh air system: adjust room temperature Air purifier (also known as "air cleaner", air purifier) refers to products that can adsorb, decompose or transform various air pollutants (generally including dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.), effectively improve air cleanliness, and are currently mainly household and commercial air purifiers that remove indoor air pollution. The effect is clear at a glance, and naturally the fresh air system is better.

I think the advantage of an air purifier is that it does not damage doors and windows, while the benefit of a fresh air system is that it has a large air exchange volume.

<> "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.

In order to improve the living environment at home, many families will now choose an air purifier or a fresh air system, so which effect is better? Today, I will systematically talk about the three aspects of use cost, comfort and use conditions, let's take a look!

What are the differences between air purifiers and fresh air systems?

1. The difference between air purifier and fresh air system - the cost of use.

1. The cost of using air purifiers.

The ** of the air purifier ranges from a few hundred yuan to thousands of yuan, and the quality varies greatly from different brands, and the quality is uneven, but the filter element can be replaced by itself, and the overall ** is also cheaper than the fresh air system.

2. The cost of using the fresh air system.

The initial installation cost of the fresh air system is high, and it needs to be designed and routed by professionals, including design, construction and purchase of fans, pipes, accessories, etc. In the later stage, regular maintenance is also required to replace the filter element.

2. Comfort.

1. Air purifier comfort.

Air purifiers can only circulate the indoor air and do not bring fresh air from the outside into the room, so the comfort is compromised. In addition, some air purifiers are noisy, and the flushing is easy to affect people's sleep when used, and the noise of the fresh air system is relatively small.

2. Comfort of fresh air system.

The fresh air system can improve the comfort of the room by introducing fresh air into the room through ventilation and supplementing oxygen.

In addition, the temperature of the fresh air after heat exchange can be adjusted to be close to the indoor temperature, and the room temperature does not drop significantly even after long-term operation. By installing different filters, the fresh air system can filter different pollutants such as dust, pollen, etc.

3. Conditions of Use.

1. Conditions for the use of air purifiers.

The air purifier is suitable for rooms that need to purify the air in a short time, and has the advantages of multiple purchase channels, no need for professional construction and installation, and plug and play. However, in the case of long-term haze days, due to the lack of ventilation, the air purifier is somewhat out of reach. Air purifiers are only suitable for air purification in a small area.

2. The conditions for the use of the fresh air system.

The fresh air system is suitable for families, schools, office buildings, etc., which are large in area and need ventilation but are inconvenient to open windows, but they need to be installed by professionals, and they also need to erect window machines and lay pipelines, which has higher requirements for the professionalism of design and installation.

The above is the difference between an air purifier and a fresh air system shared for you, I hope it will help you.
