If a hole is punched in the beam, if the beam is the main beam of the whole house, once the hole is punched, its bearing capacity will plummet, and if it encounters a geological disaster, it may break first, which has a great impact on the safety of residents.
In fact, when installing fresh air system equipment, it is not necessary to punch holes in the beam. There are two ways:
First, rational use of lintels bypasses the main girder, but lintels are generally flat. When the fresh air from the main engine passes through this lintel, the wind resistance will increase obviously and the loss of the motor will be greater. Finally, the fresh air at the air outlet will be less than the air output from the main engine air outlet. This is a phenomenon encountered when installing a central fresh air system.
Secondly, if the fresh air volume of each room needs to meet the requirements of purification and ventilation, Schmaibo's wall-mounted fresh air system suggests choosing fresh air equipment with ductless design, such as wall-mounted fresh air fan and ductless central cabinet fresh air system. This doesn't need a lintel, just make two holes near the window to purify the indoor and outdoor air through the air duct circulation. Unfortunately, every room needs to be installed. A wall-mounted fresh air system in a single room can meet the purification needs, but it seems a bit impossible to expect a machine to meet the air purification needs of the whole room.
The above is the answer of Schmaibo's home wall-mounted fresh air system, and I hope it will help you.
