Description
Technical Field
The utility model relates to the technical field of fresh air systems, in particular to a fresh air system with a noise reduction function.
Background
The fresh air system is a set of independent air processing system consisting of an air supply system and an air return system and is divided into a pipeline type fresh air system and a pipeline-free fresh air system. The pipeline type fresh air system consists of a fresh air fan and pipeline accessories, the fresh air fan purifies outdoor air to form fresh air which is led into a room, and the indoor air is discharged through a pipeline; the ductless fresh air system is composed of a fresh air fan, and the fresh air fan is used for purifying outdoor air and guiding the outdoor air into a room.
The noise of the existing fresh air system is difficult to eliminate in the use process, and great trouble is caused to daily life.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the defects of the prior art, and provides the fresh air system with the functions of noise reduction and noise reduction, and the system can ensure the air quantity and solve the problem of noise caused by the fresh air system.
The utility model is realized by the following technical scheme: a fresh air system with noise reduction and noise reduction functions is characterized by comprising a fresh air fan, wherein an air exhaust outlet of the fresh air fan is provided with a first silencer and is connected with external air exhaust through an air exhaust pipeline; a second silencer is arranged at a return air inlet of the fresh air fan, the return air inlet is connected with a return air inlet through a return air pipeline, and the return air inlets are respectively arranged in a kitchen and a toilet; and a third silencer is arranged at an air supply outlet of the fresh air fan, the air supply outlet is connected with a fresh air port through an air supply pipeline, the fresh air port is respectively arranged in a bedroom, a living room and a dining room, and a fourth silencer is also arranged at each fresh air port.
Preferably, the outdoor unit of the fresh air machine is installed outdoors.
The utility model has the beneficial effects that: the utility model reduces the noise to the external environment by arranging the first silencer, reduces the influence of the noise generated by the air return fan and the new fan to the indoor environment by arranging the second silencer, reduces the influence of the noise of the new fan to the indoor environment by arranging the third silencer and prevents the noise of the new fan from being transmitted to the indoor environment through the air supply pipeline.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the technical solutions of the present invention are further described below with reference to the following embodiments.
As shown in fig. 1, a fresh air system with noise reduction and noise reduction functions comprises a fresh air fan 1 with an outdoor unit installed outdoors, the main unit is installed at a position far away from a rest area, the outdoor unit is installed outdoors to reduce indoor noise, an air exhaust outlet of the fresh air fan 1 is provided with a first silencer 3, the air exhaust outlet is connected with external air exhaust through an air exhaust pipeline 2, and the first silencer 3 reduces noise of the fresh air system to the external environment and avoids noise pollution; a second silencer 5 is arranged at a return air inlet of the fresh air fan 1, the return air inlet is connected with a return air inlet 10 through a return air pipeline 4, the return air inlets 10 are respectively arranged in a kitchen, a toilet or other rooms, and the second silencer 5 is used for reducing return air noise, namely, noise generated by the return air fan and the fresh air fan is prevented from being transmitted to the room through the return air pipeline 4, so that the noise is reduced; the third silencer 7 is arranged at an air supply outlet of the new fan 1, the third silencer 7 is used for reducing indoor noise caused by the noise of the new fan 1, the noise of the new fan 1 is prevented from being transmitted to the indoor space through the air supply pipeline 6, the air supply outlet is connected with the new air inlet 8 through the air supply pipeline 6, the new air inlet 8 is respectively arranged in a bedroom, a living room, a dining room or other rooms, the living room and the left side horizontal type of the living room share the same air supply pipeline 6, the fourth silencer 9 is further arranged at each new air inlet 8, the fourth silencer 9 is used for eliminating the noise and the wind noise of the new fan 1 which are not eliminated by the third silencer 7, meanwhile, the wind noise generated by the new wind in the air supply pipeline 6 is eliminated, and the noise-free condition of the new wind which is sent to the indoor space is ensured, and the wind volume is sufficient.
The utility model effectively reduces the noise generated by the fresh air system while ensuring the air quantity, reduces the indoor noise on one hand, reduces the outdoor exhaust noise on the other hand, and avoids noise pollution.
Other technical features than those described in the specification are known to those skilled in the art.
