The advancement of science and technology, all kinds of new things are also emerging. When buying indoor ventilation and air -changing equipment, many people discover that in addition to traditional air conditioning, air -conditioning with some fresh air functions, the ventilation air -changing equipment is also in the ventilation equipment.The new product of the new group appeared.Many people are more unfamiliar with the new group, do not know what the new group is, and do not know its classification and principle. The following editors will introduce them in detail about these issues.
What is the fresh air unit-Xinto Unit Overview
The fresh air unit is a kind of air regulation equipment for fresh air. It is mainly composed of air inlets, motors, fans, filters, humidifiers, wind valves, air outlets and other components.Its main function is to send the outdoor fresh air to the room through a fan. When entering the indoor space, replace the original dirty air of the indoor, thereby maintaining the fresh and clean indoor air.The fresh air units are divided into three types: one -way flow, two -way flow, and full thermal exchange units. The principles of the first two new air units are simpleOK
What is the three major types of freshwind units-the new wind crew
1. One -way flow new air unit
The working principle is to rely on the suction power generated by the host work to form an indoor negative pressure. The dirty air is delivered to the outdoor by sending the air supply pipeline. In order to balance the negative pressure indoor, the relatively fresh air outside the room enters the room from the pre -installed air hole.To achieve the purpose of ventilation.The unidirectional flowing units are naturally carried out when entering the wind. The system installation pipelines are small and the installation is simple. Generally, it is mostly used for high -level houses, apartments, or office places with high buildings.
2. Two -way streaming new wind crew
The two -way streaming new air unit is a "compulsory exhaust, forced air delivery" system, consisting of a group of forced air delivery systems and a group of mandatory exhaust systems.The difference from the one -way flow is that the form of air supply is changed from natural wind to forced air delivery. The new air enters the room from the pipeline of the air supply system. The exhaust winding system is discharged out of the outdoor.The layout of the exhaust port can be arranged according to specific requirements.The two -way streaming and new air units can filter the new air introduced, the new air quality is good, and the ventilation effect is more thorough. It can be installed and used in family and public places.
3. Full heat exchange fresh air units
Full -the -rmal exchange fresh air unit is the upgrade of the two -way streaming and new air units. The host has increased the full thermal recovery system. The air in and out of the air exchanger is placed in the host. The preheating and pre -cold energy exchange can be kept. It can retain the indoor roomThe energy of 70%of the air is used with very energy -saving with the air conditioner. Even if the temperature difference is large, it will not affect the indoor temperature.Full -the -rmal exchange fresh air crew is suitable for apartments, villas, and office spaces with an area of ??less than 1,000 square meters. The new air quality is high, high -efficiency and energy saving. In many villas with comfortable 100 networks, the central fresh air installation project is used.series.
The above is the introduction of the working principle and classification of fresh air units
