Pay attention to safety when smoke is discharged from windows
In order to avoid the problem of cross smoke, some owners give up the
original flue and directly open holes in the windows for smoke exhaust.
This is OK, but there are several points that need to be paid attention
首先在窗户或墙面泥杆 保定空压机 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修 托辊设备 托辊生产线开洞之前一定要经过物业的同意;其次注意安全问题，一般排烟管末端是金属材质的，如果开的洞太小，金属传热可能会使玻璃炸裂，伤及行人，且烟管通向窗外，强劲的北风对着吹会导致油烟倒灌。最好将管道伸出去以后把管道往下窝，这样还可以避免下雨时雨水流进管道，并把风挡在外面
First, the consent of the property must be obtained before opening a
hole in the window or wall; Secondly, pay attention to safety.
Generally, the end of the smoke exhaust pipe is made of metal. If the
hole is too small, the metal heat transfer may cause the glass to crack
and hurt pedestrians. In addition, the smoke pipe leads to the window,
and the strong north wind will cause the oil smoke to pour back. It is
best to stretch out the pipe and then nest it down. In this way, it can
also prevent the rain water from flowing into the pipe when it rains and
keep the wind shield outside
