Shenyang Ventilation Engineering Construction skills in hotels

hotel Ventilation engineering It is a kind of municipal infrastructure that can make the air circulate and reduce the concentration of harmful gases. It plays a big role in life. So what are the skills of air duct construction in hotel ventilation engineering?

1. Before construction, the engineer in charge of the equipment shall draw the pipelines and single lines of each type of work on a plan. Use one color pen for each type of pipe. Synthesize the elevation at each intersection to see if there is any contradiction, find it in time, and solve the problem before installation.

2. Solve various problems Ventilation duct The principle of collision and coordination is generally: "small pipes give way to large ones, and pressure gives way to non pressure". For example, if the water pipe collides with the air pipe, the water pipe should turn. If the cold and hot water pipes collide with the sewer pipe, the cold and hot water pipes shall be changed.

3. In order to reduce investment, save space and reduce floor height, some pipes without slope requirements can be laid through beams, such as water pipes, fire sprinkler main pipes, etc.

4. For more complex civil buildings, in the design phase, various types of work, such as HVAC, water supply and drainage, power supply and lighting, and the building discipline should negotiate space separation and determine the elevation range of each type of pipe. Generally, you should not go beyond the limits set for yourself. In case of a pipeline section crossing the boundary, it shall negotiate with other works of the hotel ventilation engineering.

Whether it is necessary to conduct thermal insulation for the air duct in the ventilation project mainly depends on what role this air duct plays in the ventilation project.

Generally, air ducts for thermal insulation work need to play these two roles:

1. Heat preservation: the purpose is to slow down the heat transmission speed and reduce energy loss.

2. Prevention of condensation: the air duct in the ventilation project will produce condensate, so the air duct needs to be treated to prevent condensation.
