The fresh air system is different from the air purifier, it is a collection of systems, composed of pipes, host filter devices, air outlets and so on. The central fresh air system needs to reserve air outlets and determine the direction of the pipeline, etc. Therefore, it is necessary to determine whether to install the fresh air system in the pre-renovation stage, and the specific plan needs to be planned in advance. Because the pipeline type fresh air installation needs to hide the host and the pipeline in the ceiling, * synchronized with the previous decoration, if the decoration has been completed or the ceiling, Shiyang Electromechanical recommends that you can choose the wall-mounted fresh air!
Fresh air system installation steps and precautions
During the installation of the central ducted fresh air system, all links and steps must be reasonable, formal, and rigorous. A good installation process can effectively ensure the efficient operation of the system in the later period. In the HVAC industry, the "three-point product, seven-point installation" is also the same It is suitable for fresh air system, so Shiyang recommends to find a regular, powerful and qualified company to install fresh air system for your love home.
On-site positioning
Before installing the system, do on-site positioning, confirm the installation plan, confirm the positioning of equipment, tuyere, controller, etc., and return air way, pipeline layout, and trend.
Basic finishing
The basic finishing operations include opening, grooving, framing, wall-penetrating, beam-penetrating, and floor slab opening. Before installing new ducted fans, you must confirm which walls in your home can be perforated. Before construction, consult the property first You can punch holes.
Indoor fresh air host installation
The installation location of the main unit of the fresh air system should consider factors such as maintenance, noise impact, and intake air quality. Hoisting should be stable. After the host is installed, dust protection should be done.
Pipe installing
When installing pipelines, try not to use 90-degree elbows, use two 45-degree elbows in combination, and use oblique tees to reduce wind resistance. Make good air leakage treatment at the pipeline connection. The outdoor air vents and external wall holes should be kept at a slope of 1: 100 to avoid rainwater inflow. At the same time, the fresh air system can also choose two forms of top air supply or ground air supply.
Tuyere installation
If the outlet and return air outlets of the fresh air system are too close, the fresh air outside will not be fully discharged into the room. The distance between the outdoor air inlet and outlet should be greater than 1000mm to prevent fresh air that has just entered the room from being discharged immediately.
Controller installation
The wiring is firm, the panel installation position is reasonable, and the process is beautiful.
Commissioning acceptance
The power-on adjustment test is accepted to confirm whether the host is operating normally, whether the pipeline and the host are fixed without vibration, whether the pipe connection is tight, whether the air volume and noise are normal, and then delivered to the customer.
