In HVAC CAD design In the process, what should I do if I want to quickly calculate smoke exhaust? In this section, we will learn about Haochen together with our editor CAD The HVAC software can quickly calculate the specific operation steps of smoke exhaust by calling the mechanical smoke control system!

Smoke exhaust calculation steps in HVAC CAD design:

Step 1: Create a new subsystem. Use the right-click menu to describe it.

1. Right click Mechanical Smoke Control System in the project tree on the left of the interface to pop up the right-click menu, as shown in the following figure:

2. Click [New System] in the right-click menu to open the new system dialog box, enter [System Name] and [No.], and [Smoke Control Part] can be selected from the drop-down box. As shown in the figure below:

3. Click OK in the above interface to complete the system creation. The newly established system is added to the project tree on the left side of the interface, and the calculation interface of this system is displayed on the right side of the interface. As shown in the figure below:

Step 2: Input parameters in the calculation interface and generate the results in real time.

1. Basic parameters:

The [Smoke Control Part] reads the [Smoke Control Part] in the [New System] interface and cannot be modified.

[Air supply type] can be selected from the drop-down box. When different air supply types are selected, the interface parameters will change accordingly.

[Front room evacuation door setting] Use the [+] [-] buttons on the right side of the figure below to add or delete doors; The parameter items in the list can be modified after clicking.

The user only needs to enter the basic parameters that can be edited. Other non editable parameters are automatically queried or calculated through other parameters or conditions (AK, Ag, L1, L3, etc.). As shown in the figure below:

2. Calculation of mechanical pressurized air supply volume of Ls antechamber: when the basic parameters are selected and entered, the calculation results are automatically generated. The results include formula calculation values and table lookup values, and the software will automatically calculate according to the conditions and specifications. As shown in the figure below:

3. Design value: according to the specification requirements, the design air volume of mechanical pressurized air supply should not be less than 1.2 times of the calculated air volume. The default value of correction coefficient here is 1.2, which allows users to enter freely. The calculated air volume is the larger value between the formula calculation value and the table lookup value. As shown in the figure below:

4. Formula calculation: the wind speed can be calculated according to the area of the air outlet, or the area of the air outlet can be calculated according to the wind speed. Switch through the radio button, and the data items will change accordingly after switching. Only input parameters, and the calculation results will be generated automatically. The shape of the air outlet can be switched and selected. When it is rectangular, enter width and height, and when it is circular, enter radius. As shown in the figure below:
