Which is better ductless fresh air system? Which is the best fresh air system?

It is better to have a fast clean fresh air system without pipes, which can be installed on the balcony or indoors, and it is very convenient to install without pipes, and the air purification is good, which is reduced to below 10.

Corodito is cost-effective and has a long warranty.

No ductless fresh air system feng shui house is good.

Feng Shui House Fresh Air System can be installed both indoors and outdoors. The purification effect is good.

Just learned about this, look at the introduction is to install an exhaust device in the bathroom or kitchen, and discharge the indoor dirty air and water vapor to the outside through the air duct of the bathroom or kitchen, so that each room in the room forms a negative pressure, and the outdoor fresh air flows naturally into the room after being filtered through the window air inlet or wall air inlet under the action of negative pressure, so as to complete the entire air replacement process. Because there is a pressure difference between indoor and outdoor, it is theoretically no problem for outdoor air to enter the room without relying on any external force, but considering the resistance of the filter, even if the air can enter the room, the air volume will not be too large, and the purification effect will be very slow, and the sealing requirements for the house are very high, because the filtered air is easy to come in, and the unfiltered dirty air is also easy to pass through the window gaps.

Secondly, although this kind of fresh air does not need to lay pipes, it is inevitable to punch holes in the wall, because the air inlet and outlet are required, and the filter screen replacement is inevitable.

In fact, the main reason for most people to install fresh air is to realize the function of indoor and outdoor exchange, although this kind of ductless fresh air does not solve other drawbacks of traditional fresh air, the installation method is still perfect, more convenient, but compared with the current negative ion purification from the installation and use, later maintenance, purification mode and other aspects are still lacking. Negative ion purification does not need to make a hole in the wall, it can be used when plugged in, secondly, negative ion purification relies on the combination of negative ions and particulate pollutants in the air, condensed into a clump and settled to the ground, to achieve the effect of purification, especially the ecological anion generation chip technology, Nazi fullerene anion releaser technologyThere is a pollutant collection systemNegative ion purification, the generation is highly active small particle size negative ions, can quickly diffuse to the entire space range, the purification efficiency is relatively fast, no filter, no consumables cost. Moreover, because there is no fan, the negative ion purification will not drive the air flow in the room and will not affect the use of the window.

The fresh air system is a set of independent air handling systems composed of air supply system and exhaust air system, which is divided into two types: ducted fresh air system and ductless fresh air system.

Ducted fresh air system.

The pipeline fresh air system is composed of fresh air fans and pipe fittings, the outdoor air is purified by the fresh air fan and then introduced into the room, and the indoor dirty air is discharged outdoors through the exhaust outlet pipe. Most ducted fresh air systems on the market are bidirectional flow fresh air systems, i.e., forced inlet air and forced exhaust air.

Features: 1. Centralized ventilation, controllable air volume.

2. The air inlet and outlet can be distributed to each room, and the ventilation and purification effect is more significant.

3. The life of the pipeline is limited.

4. It is necessary to punch holes in the load-bearing wall to complete the installation, and the amount of work is large.

5. It is more suitable for industrial or large-area office use.

No ducted fresh air system.

The ductless fresh air system is composed of a fresh fan and a breather, which purifies the outdoor air into the room and discharges the indoor dirty air by the breather.

Features: 1. There is no need to lay pipelines, and the installation is convenient.

2. It does not involve the life of the pipeline.

3. There are requirements for the air inlet, and the purification and ventilation of the room are poorer.

4. The amount of work is small, suitable for home installation.

Of course, no matter which fresh air system the user chooses, it should be measured according to their own needs and room layout. Good air is in the creation of poetry and new wind!
