Description

Multi-mode ventilation system and air conditioner

Technical Field

The utility model relates to a multi-mode ventilation system and an air conditioner, and belongs to the technical field of air conditioners.

Background

Since people live indoors for most of the time, the indoor air quality is closely related to the health of human bodies, and therefore, the purification treatment of indoor air is more and more important. From the air flow direction, the principle of air purification can be divided into two main categories: the indoor air is internally circulated and purified, and is represented by an air purifier, and when the indoor air continuously flows through the air purifier, particulate matters and viruses in the air are removed or killed by virtue of functional components such as dust removal, sterilization and the like arranged in the indoor air, so that the indoor air is purified; the other type is to continuously introduce outdoor fresh air, and dilute and replace the indoor air, which is represented by a fresh air blower and a fresh air conditioner. The fresh air dilution and replacement can be divided into unidirectional micro-positive pressure fresh air replacement and bidirectional fresh air replacement, wherein the unidirectional micro-positive pressure fresh air replacement is carried out, fresh air is introduced from an outdoor single side into a room, and indoor air is kept at micro-positive pressure and continuously discharged; the two-way fresh air flow is realized by taking air into the room from the outside and exhausting air from the room, and the ventilation in two directions is realized by taking work through a fan, so that the aim of purifying the indoor air is fulfilled.

For example, when the one-way micro-positive pressure fresh air exchange is performed, and the fresh air is introduced to reach the indoor air saturation pressure, the sealing performance of a room is better and better due to the fact that the room is decorated in a new room, at the moment, the indoor air is difficult to discharge to release the pressure, and even if a fan runs, the indoor and outdoor air exchange effect is greatly reduced. For another example, the two-way fresh air flow is changed, the air is actively blown indoors through the fans, and is exhausted outdoors, two sets of air pipes (namely an air inlet pipe and an air outlet pipe) are usually needed, and sometimes two fans are needed, so that the whole machine structure space is occupied, the cost is high, and the after-sale installation is complex; and the bidirectional ventilation air is short in distance between the air inlet and the air outlet, and fresh air just introduced into the room is limited in air supply distance, so that the fresh air is easily directly discharged out of the room. The air purifier is not as good as indoor and outdoor fresh air exchange for exhausting formaldehyde gas released continuously during new house decoration, and the single machine has high purchase cost, needs to occupy expensive indoor space, and is not economical.
