Fresh air can maintain good health. A fresh air system can improve indoor air and keep it clean. The installation of the fresh air system has an important impact on the effectiveness of the fresh air system, and its installation steps include pipeline perforation, host lifting, pipeline installation, duct and host connection, air inlet installation, exhaust installation, installation, but also good protective measures.
How to install the fresh air system?
1. Pipeline perforation
All pipelines through the wall holes, always use a mechanical perforation machine to open holes, the need to punch through the wall of the location of the structural conditions to meet or be permitted, can not be destroyed at the expense of the overall structure of the room, the size of the holes is based on the size of the pipeline to determine the location of the location according to the construction drawings to locate the exact.
2. Host lifting
The host is generally installed in the balcony, kitchen, or bathroom ceiling, not too long from the air duct, machine installation is best to direct contact with the air duct, the machine to the wind or flue should minimize the bend to reduce resistance. The installation position of the main machine should be correct and kept horizontal. When installing, the host boom nut must have anti-loosening measures to ensure that the installation is solid, to avoid running noise. Below the junction box of the host, there must be an access port, and the host installation location must be easy to install and maintain.
3. Piping installation
Pipe installation should be horizontal, and vertical, as far as possible to ensure the level, and not allow too much error. The inner diameter of the pipe is clean and free of debris. The direction of the pipe, pipe diameter, and the installation location of the air outlet should be in line with the requirements of the design drawings. The installation piping should be fixed by a supporting bracket. If a hoop is used, its inner surface should be close to the outer wall of the pipe. The bracket and pipe should be fixed firmly without loosening.
4. Connection between the air duct and host
In principle, aluminum foil or fireproof canvas is used to connect the air duct and the host with a flange. The aluminum foil or fireproof canvas should not be twisted and should not be used as a connecting pipe or reducer to find a level. Aluminum foil or fireproof canvas should be an appropriate degree of tightness, as the soft connection of the return air duct should be properly taut, to prevent suction deformation and reduce the cross-sectional area.
5. Inlet installation
Air inlet should be installed in the window sill below and easy to install position, try to avoid dead ends, so that the new air and indoor dirty air form a circulatory system, to maintain continuous circulation of indoor air circulation; installation should be firm, the air inlet inside and outside should be tightly pressed against the wall or window frames; the installation process with the glass adhesive for sealing.
6. Air vent installation
A bathroom air vent should be installed on top of the toilet as far as possible, indoor air vent should be installed above the door frame as far as possible, so that the new air and exhaust air from a ventilation circulation system, so that the indoor air is always circulating, to maintain freshness; air vent installation should be firm, the air vent must be close to the wall or roof.
Protective measures during the installation of the fresh air system
1. Pre-installation protection preparation:
Prepare the ground protective cloth and furniture protective cloth.
Prepare a waterproof cover and dustproof cover for perforated equipment.
Prepare clean rags and sandpaper.
2. Protection during installation:
Cover the protective cloth on the furniture and floor in the installation room;
Protective cover must be installed when drilling the water drill;
Immediately after drilling, wipe or sand off the wall pollutants.
3. Protection after installation
After the end of the installation, the installation of the rubbish generated by the installation to the self-provided preparation of bags or cardboard boxes, stage after the construction of the removal of the outdoors within the designated location.
If necessary, in advance of the cleaning company personnel go to the health professional cleanup.
