How to design exhaust system in hotel club design.

In the design of hotel club, the design of exhaust system can not be ignored. A good exhaust system has a great influence on the air quality designed by the hotel club, and will not give the guests a dull feeling. For example, some living rooms and equipment rooms, such as the dark bathroom in the basement of a project, have set up an exhaust system. The horizontal wind length is 60 m and the cross section is only 200 mm? 00 mm, the wind resistance is larger; It is very uncoordinated to choose the roof ventilator to exhaust air, but install the fan on the external wall. There are also a number of darkrooms in the basement of the project. Each room adopts a ceiling exhaust fan, and the exhausted air is discharged to the outside through a horizontal air duct with a cross section of only 150 mm? 50 mm, large resistance, poor exhaust effect. A project includes command hall, conference hall, computer room, etc. The ideal air conditioning system for this kind of room should be low-speed air duct system, and the fan-coil system should not be used in the design of hotel clubs. For this kind of residence, the fan coil system is adopted in the decoration design, and there is no fresh air supply system. This kind of system selection is often unreasonable and can't meet the needs of the owners to a great extent.
