Is it necessary to install a fresh air system during renovation? What is the difference between a fr

It is necessary to install a fresh air system when decorating. The difference between a fresh air system and an air conditioner is that the fresh air system uses the circulation of indoor and outdoor air to ensure indoor air quality.

There is no need to install a fresh air system when decorating, because the air conditioner is quite comfortable; Air conditioning regulates indoor temperature through cooling and heating, while fresh air system uses indoor and outdoor air circulation to ensure indoor air quality.

In the process of home decoration, you can choose to install a fresh air system according to the structure of your own home. If the ventilation and lighting are not very good, be sure to install it.

The greater effect of the fresh air system is to ensure that the indoor air is physically and mentally healthy, while the air conditioner is just to adjust the indoor temperature. Therefore, the air conditioning and fresh air system are two separate operating systems in the room, one is to adjust the temperature and the other is to improve the indoor air quality, each of which deals with two problems in the natural world of everyone's house. There will be no problem that the air conditioner cannot be turned on.

When we turn on the air conditioner, we usually close the windows and doors to create an airtight indoor space. The development of the fresh air system industry is in its infancy, and there are many intermediate fresh air systems on the market at present, and <>

It is indeed very complicated to assemble: it is necessary to assemble a very heavy server on top of the decoration ceiling, and then assemble the ventilation duct, which is quite expensive to install. Shiyang Mechanical and Electrical Engineering feels that the assembly of the middle fresh air system has long been very perfect, and there is no problem if you find a formal enterprise.

Coupled with the occurrence of the first fresh air system, these points have already been completely overcome. All you need to do is drill an air hole in the wall, suspend the machine in the wall, and you can enjoy clean air! But nowadays the outdoor air index is not ideal, <>

If you want to improve the natural environment of indoor air, you also need to rely on air purifiers, and the fume purifier is different from the fresh air system, which is usually for the indoor air circulation system to carry out purification treatment. The biggest difference between the fresh air system and the intermediate air conditioner is its efficacy, the middle fresh air system focuses on the indoor and outdoor gas exchange, and the intermediate air conditioning system software focuses on cooling and heating. Generally, the fresh air system used by everyone in the family is a dual-flow fresh air system that removes the waste heat of haze weather, and <>

In the overall state, a slim server and two inlet and outlet air ducts form a separate safety passage for the fresh air system and exhaust air system, and the indoor and outdoor gas exchange is carried out. The fresh air system should be configured in areas with poor air quality and serious haze, and customers who have just finished decorating and have heating at home should choose the system software. The intermediate air conditioning system software, especially the artifact of summer temperature reduction in the stuffy area, can be selected for whether the intermediate air conditioning can be applied, but the air conditioning is the best way to deal with the summer heat.

With the improvement of living standards, many people are more and more concerned about air quality, such as air fresheners and other products are especially concerned by consumers. Maybe the fresh air system is visually very similar to the air conditioner, but the two are not the same product, the following will introduce the difference between the fresh air system and the air conditioner, if the fresh air system is installed, do you still use the air conditioner?

1. The difference between fresh air system and air conditioner.

Air conditioning regulates indoor temperature through cooling and heating, while fresh air system uses indoor and outdoor air circulation to ensure indoor air quality. Generally speaking, air conditioners use the function of cooling and heating to keep the human body at a relatively comfortable temperature, while the fresh air system can ensure the freshness of indoor air. Because in summer, if the doors and windows are closed for a long time, the air conditioner will be turned on, which will cause the indoor air to be very dry, and if the fresh air system and air conditioner are turned on at the same time, the air will be clean and refreshing.

2. Do you still use air conditioning for installing fresh air system?

When many businesses advertise the fresh air system, they say that it achieves the effect of cooling and heating, but this is actually a wrong concept. Because the "total heat exchanger" of the fresh air system is used to balance the temperature difference between indoor and outdoor, when it is running, when the indoor dirty air and the outdoor fresh air flow through the heat exchanger core in a positive manner, due to the temperature difference and vapor partial pressure difference between the airflow on both sides of the airflow separator, the heat and mass transfer phenomenon is presented when the two airflows pass through the separator, causing the total heat exchange process. However, without the assistance of air conditioning, the indoor and outdoor temperatures are the same, and the fresh air system cannot effectively change the indoor temperature, so if you want to cool down, you still need air conditioning.

3. Can the air conditioner with fresh air function replace the fresh air system?

When the indoor pressure is equal to or higher than the outdoor, a closed circulation system is formed between the room and the air conditioner, which cannot achieve the purpose of indoor and outdoor air exchange, that is, there is no fresh air, but this can ensure that the indoor temperature reaches the set fixed value; The fresh air system is to exhaust the turbid indoor air through ventilation, bring in fresh outdoor air, realize the circulation of indoor and outdoor air, and the fresh air system can effectively change the indoor air quality. To put it simply, the advantage of the fresh air system compared with the "fresh air function" of the first air conditioner is that it will exhaust the dirty air to the outside, and the air pumped in will be filtered more carefully and reliably.

4. Recommendations. Generally speaking, the "household fresh air system" can work in coordination with the first air conditioner, which can not only ensure that the indoor temperature meets the set expectations, but also effectively get fresh and clean air. In addition, when the outdoor temperature is high in summer, if the indoor heat exchanger enters through the fresh air system "full heat exchanger", the total heat exchange rate is close to 80%, which will greatly reduce the fresh air temperature, so that the indoor air conditioner does not need to consume more energy to cool down.

The above is the difference between the fresh air system and the air conditioner, and the relevant introduction to the air conditioner when installing the fresh air system.

Fresh air systems are not a household necessity, and whether they need to be installed depends mainly on the family's financial conditions as well as personal preferences. The fresh air system can effectively improve the indoor air quality, if you want to improve the quality of life, you can still install a fresh air system. But if the air quality is good in the area where the Leaky Forest lives, there is no need to install it.

In addition, the installation of fresh air system often tens of thousands, and the later stage also needs to be cleaned frequently, which greatly increases the decoration cost and personal energy.

What are the advantages of the fresh air system?

1. Fresh oxygen.

The fresh air system is to introduce fresh air from the outside through punching, and then filter it into the room, the air has a high oxygen content, even if you don't open the window, you can enjoy the fresh air, just like a natural oxygen bar.

2. Filter haze.

Smog occurs frequently and harms the body. However, it is important to know that this fresh air system has a built-in high-efficiency filter, so it has a strong filtration effect on the same fine particles.

3. Sterilization. Bacteria and viruses can be said to be the easiest to breed indoors, and the fresh air system can effectively remove the virus with a reasonable airflow circulation power. At the same time, it can also have an effective sterilization function, compound multiple killing bacteria and viruses, so that these bacteria can be kept away from vulnerable groups such as children and the elderly, and make the home safer.

4. Solve the problem of ventilation in winter.

Many friends don't like to open doors and windows for ventilation in winter, because the outdoor temperature is very cold in winter, and if you open the doors and windows, it is easy to cause yourself and your family to catch a cold. However, if there is no ventilation for a long time, it is easy to cause the physical state of users and their families to deteriorate. If the user's home is equipped with a fresh air system, then even if the user does not open the doors and windows for ventilation, he can still enjoy fresh air indoors.

What are the disadvantages of the fresh air system?

1. Loss of indoor cooling (heat) capacity.

The fresh air system cleans the indoor air conditioner by continuously exhausting the air supply, which will cause a certain loss of the indoor air conditioner when the air conditioner is used at the same time in summer, and the same is true in winter. However, a full heat exchanger (a type of fresh air system) can reduce indoor energy loss and is very energy-saving.

2. There is a certain amount of investment in the early stage.

Buying a fresh air system** is related to a number of factors. **Cheap, poor performance, high energy consumption, not enough comfort. The intelligent fresh air system with a good point has relatively more investment in the early stage, and of course, the later cost of this kind of fresh air system is also fast.

3. The filter needs to be replaced regularly.

If the fresh air system is not cleaned in time, it is likely to become a source of indoor pollution, so it is necessary to replace the filter and movement of the fresh air system or fresh air device frequently. Replace it once every 2-3 months, and when the air quality is not good, it is recommended to replace it once a month.

I don't think it's necessary to install it for those who have a small home. It is safe, convenient, environmentally friendly, easy to clean up, and does not emit odors.

I think it is necessary because the fresh air system can ensure the circulation of indoor air; It can prevent dust, prevent air conditioning diseases, remove germs, prevent mold on furniture and clothing, and reduce indoor carbon dioxide concentration.

Personally, I think it is necessary to install a fresh air system, which can make the indoor air fresher; It is easy to install, can remove formaldehyde, has a long service life, is very intelligent, and is cost-effective.

Personally, I think it is necessary to install a fresh air system; The price is favorable, good for the human body, low noise, small size, and very convenient to use.
