Can fresh air air conditioners replace the fresh air system?

Although August has "established autumn", the cool breeze in the north has gradually arrived, but the south still keeps high temperatures. "Autumn Tiger" down the mountain is very difficult. The air conditioner has become a renewal artifact. The fresh air air conditioner has also entered the public's vision and quickly expands. But is the "new wind air conditioner" the same as the fresh air system function? Does the "New Wind Air Condition" not need a fresh air system?

Although the new air conditioner of the new air conditioner is fundamentally the same as a professional new fan, its performance is essentially different. In short, the new wind air conditioner is to add a new air module to the air conditioner, simply filter the outdoor air, and send it to the room after cooling or heating, to achieve the so -called "fresh air" effect, but the fresh air is only the additional function of the machine. The main function is to adjust the temperature. As a professional ventilation ventilation equipment, although the role of temperature adjustment is limited, its main function is to improve air cleanliness. , So it is impossible to replace each other between the two.

01 new air volume

The most basic function of the fresh air system is ventilation and ventilation. Through the fan and independent new and exhaust systems, it continuously introduces fresh air outdoor air, and discharges indoor visceral air to achieve indoor and outdoor air circulation. Choose a new fan with a suitable air volume when purchasing, which can meet the new wind purification needs of the whole house and provide a clean and oxygen -rich air.

At present, most of the fresh air air conditioners on the market are single-room hanging air conditioners. The amount of fresh air is concentrated in 40-80m³/h. It can only cover one room and meet the new air needs of 1-2 people. In addition, to achieve the new air volume of propaganda, the reserved 6cm pores reserved in traditional air conditioners are not enough. It is necessary to expand the pores to reduce the loss of fresh air and achieve lower noise.

02 purification function

In the fresh air system, filtering device is particularly important. Most of the fresh air systems are equipped with different functions of different functions. Such as the far -reinforcement system, equipped with a three -level filter with "thick -effect filter+electrostatic dust collector+H13 -level high -efficiency filter", multi -stage filter combination can filter PM2.5 in the air 99.9%, kill bacterial viruses such as A flow, Under the layers of the filter, the fresh air entering the room is clean and non -polluting.

Affected by the size of the air conditioner model, the fresh air air conditioner cannot be equipped with a large -sized, high -precision filter. The introduction of the fresh air is only sent to the room after a shallow filter. Once the outdoor air quality is poor, the purification effect of the new air conditioner will be the purification effect. Very limited.

At present, many fresh air air conditioners have four to six -level filters, which seem to be powerful, but in fact, the dust cover containing the air conditioner itself, the level of the filter is low, the dust capacity is limited. Fine particles play a first -class HEPA filter. Due to the heavy burden of the HEPA filter and the short service life, it needs to be replaced frequently, and the cost of later use has increased.

03 Energy -saving effect

When it comes to later use costs, there is another thing that cannot be ignored is the power consumption of the machine, which is also the focus of consumers when buying electrical appliances.

The fresh air system needs to turn on the air to purify the whole house for 24 hours to save energy. At present, the high -end fresh air system is equipped with a full thermal exchangeer, which can recover the heat or cold volume in the exhaust air supply of the fresh air, so that the air coming in outdoors is closer to the air closer to the outdoor air closer to the outdoor air closer. The indoor temperature and humidity ensure that the indoor personnel are comfortable and comfortable, and it will not cause much pressure on the air conditioner. Taking the far fresh air system as an example, the thermal recovery efficiency of the full heat exchange can reach up to 80%, and it can be turned on 24 hours a day. It only costs 1-2 degrees of electricity, which saves energy consumption to the maximum.

The fresh air air conditioner is a one -way flow product, that is, "forced air delivery+natural rowing wind", using positive pressure to bring fresh air to the indoor, and "squeeze" the indoor dirty air through the gap between the doors and windows. The air that has reached a comfortable temperature in the room is directly discharged, and the indoor cooling or calories will be lost. The fresh air sent into a series of refrigeration or heating treatment is needed to increase the workload of the air conditioner. The power consumption is very high, which is not conducive to energy saving.

04 noise

Generally speaking, the noise of the machine is affected by factors such as outdoor sound sources, fan power, and pores. When using air conditioners and fresh air, do not need to open windows, which can effectively separate outdoor noise. Therefore, noise is mainly due to the machine itself and air duct wind speed.

There will be thick mute materials in the fresh air system, which runs quietly, has a low sense of existence, and is generally installed in the kitchen, toilet ceiling or balcony, which is far from the living room. At the same time, it is effective to control noise and does not affect daily life.

The fresh air air conditioner is generally installed in the bedroom, and the running volume is slightly larger, which will affect sleep.如果空调没有扩孔安装，必然会挤压新风管的截面积，更细的管道意味着单位时间内输送的新风量下降，而要保证合适的新风量，则需要增大出风速度，而This will inevitably bring noise.

In summary, fish and bear's paw cannot be available. Although the new wind air conditioner has a fresh air function, it cannot completely solve the problem of indoor air quality. When improving the quality of indoor air, the fresh air system will not affect the indoor temperature too much. TwoCan not replace each other.As far as the current technology is concerned, the forced combination of fresh air and air -conditioning functions will only increase consumption and reduce work efficiency.Therefore, if the budget is sufficient, it is recommended that you install the air conditioner and the professional fresh air system alone. The cooperation between the two can maintain a comfortable temperature and enjoy the clean air to create a more comfortable home environment.
