In addition to ventilation, fresh air system can adjust the air temp and humidity into the room, so that we feel more comfortable indoors, and gradually become a necessary choice for modern home.
Do we need to plan before installing fresh air system?
The fresh air system is different from the mobile air purifier. The system components include pipes, filters and other devices. The central fresh air system needs to have 1-2 vents in each room. Therefore, in the pre- decoration stage, it is necessary to determine whether the system needs to be installed, and the specific installation plan needs to be planned in advance.
Fresh air system includes pipe type and wall hanging type. When installing the pipe type fresh air system, the main engine and pipe should be concealed in the ceiling, and it is better to proceed synchronously in the early stage of decoration. If the decoration has been completed, in order to minimize damage the household decoration, you can choose to install wall-mounted fresh air fans, just need to punch holes in the outer wall.
A. Installation of indoor fresh air mainframe
Maintenance, noise and inhalation air quality should be taken into account when installing the main engine of fresh air system. The installation position of the main engine should be far away from the humid area such as kitchen. The lifting should be smooth and ensure that the hanging parts have enough strength to bear the weight of the main engine. After the installation of the main engine, it is better to pack it with fresh-keeping film and do a good job of dust-proof protection.
B. Pipe installation
When the pipeline is installed, the connection with the hard nozzle of the main engine should be protected against vibration. Soft connection is adopted at the connection with the main engine to prevent resonance. When two pipelines intersect, the elbow should be used, and the soft joint should not be used. Pipeline elbow should not use 90 degree elbow as far as possible. Two 45 degree elbows should be combined and three-way should be inclined to minimize wind resistance. Pipeline connection must be well treated for air leakage and connected with special glue. Outdoor vents and wall holes should be kept at a slope of 1:100 and rainproof treatment should be done to avoid rainwater irrigation. When installing the fresh air outlet, the outdoor rainproof cover should be firmly installed. The edge of the hole should be sealed with glass glue, and the indoor air outlet should be tightly and firmly installed.
The fresh air system can choose top air supply or ground air supply. The top air supply pipeline uses circular pipe and the ground air supply pipeline uses flat pipe to minimize the loss of air pressure.
C. Tuyere installation
If the distance between the outlet and outlet of the fresh air system is too close, the fresh air from outside will be discharged if it does not reach the room adequately. The distance between the outlet and the outlet should be more than 1000mm, so as to avoid the fresh air from the room being discharged immediately.
