What about the exhaust and return air of the hotel?

Treatment methods of hotel exhaust and return air;

1. In this case, we can consider installing another check valve in the smoke exhaust pipeline. Some kitchen range hoods are equipped with check valves, which can effectively prevent the backflow of lampblack after installation. However, it should be noted that it needs to be cleaned in time after a period of use, otherwise it will be ineffective.

2. Although someone installed a check valve, if the sealing work is not done well, such as some loopholes, it will lead to the problem of random charging of oil smoke. In this case, we can stick the surroundings firmly with sealant or adhesive, and once the flue is opened, it cannot be replaced at will.

3. Sometimes, because the smoke exhaust pipeline is too long, the oil fume will accumulate in the pipeline for a long time, and it will also cause the pipeline to bend, so it is difficult to discharge the oil fume, and the problem of oil fume backflow is most likely to occur at the interface, so it is necessary to shorten the pipeline within a reasonable range, so as to solve the trouble of oil fume backflow.

Install the exhaust pipe of the range hood.

When installing the range hood, the masters will install the exhaust duct in place by the way. Generally speaking, if there is a ceiling in the kitchen, we can access the exhaust pipe of the kitchen from the ceiling end. One advantage of this is that we can avoid facing the oil fume pipeline, and at the same time, we can effectively avoid the problem that the distance of the oil fume pipeline is too large.

However, we should pay attention to this installation method, and check the installation of the ceiling at the smoke crossing. If it is necessary to move down, the space reserved at the upper part should be taken into account, and there may be gaps when installing the smoke exhaust pipe. Be sure to seal it to prevent the pipe from falling off.
