There are several ways of inserting circular clean caps. There are the 2 left icons for inserting a clean cap in end of a duct or fitting and there 2 icons for inserting a saddle tap + a clean cap or a tee + a clean cap in one command.

Product with no connection e.g. products like fan Coils w no duct connection

It is possible in CADvent to convert symbols for products with no connection to CADvent objects which then can be shown and used in the BoM.

Make the special symbol 1. Click the Special symbol icon 2. Select AutoCAD objects

representing the product 5. Select the insertion point 6. Add data to the product

Scrambler tap

The scrambler tap function is very useful when making non standard connections like taps from circular elbows or rectangular to circular transitions

1. Draw the circular tap towards the point the scrambler tap shall be made. You can use OSNAP like “nearest” to get a close point.

Please note that the distance between the end point of the duct and object that shall be connected must be less than the maximum connection distance set in project settings.

2. Select the Scrambler tap option in

the continue command 3. Select the object to connect to. 4. The objects are connected.

Short bends

Short circular bends are very useful in tight situations.

Manual insertion of short elbow The short elbow can be found among all the other circular bends.

Make the short elbows the automatic choice Select the short elbow the one with highest priority.

1. Go to product default settings 2. Move the short elbow to the top 3. Use the continue command to see

that the change is made.

Constant flow dampers

These types of products are very useful to control the flow in a system. CADvent has embedded functionality for calculating system with these kinds of products.

Select product

1. Select the product from the constant flow damper icon

2. Set the flow 3. Insert the product as normal

dampers

Calculating with constant flow dampers

When calculating systems with inserted constant flow dampers the thing that sets the flow on diffusers “below” the constant flow damper are the pressure loss in between the branches and the flow set on the CAV damper.

2D for CAV dampers

The 2D for a CAV damper is different to “normal” dampers to visualize the difference.

Change flow on CAV dampers

1. Use properties 2. Go to the CAV controller tab 3. Change flow 4. To update the system use the

calculation

Facilis calculation

These diffusers are configurable and when delivered their nozzle setup is pre set to get the right flow and pressure. The products make the balancing very easy but the hard job is normally to select the right nozzle configuration but in CADvent this data is made automatically.

Select the product

1. Select product to be used in air device dialogue, Comfort Express

2. Set flow 3. Set minimum pressure 4. Insert product in drawing The product is now configured for the flow and minimum pressure.

View product code with configuration setup

1. Use the list command or 2. The text command to see the

configuration setting. In the code FCL-NZ-160-304-60-X, the 304 is the nozzle setup.

Change product data and get new product configuration w. properties

The data of the FCL product can be changed in the property dialogue.

1. Set new flow or/and set new pressure

2. Click on OK 3. New product code is shown

The product has many possible configurations and CADvent selects the closest.

Change product data and get new product configuration w. calculation

When the diffuser is inserted the nozzle configuration is locked, fixed damper position. If you want CADvent to set different data on all diffusers to get exact balancing go to properties and unlock the position. If the position not is unlocked dampers will be inserted, if needed. The flow distribution can be shown by using simulation in the calculation. 1. Select properties 2. Select products 3. Go to the Flow controller tab 4. Change the damper state to Unlocked 5. Calculate The product has many possible configurations and CADvent selects the closest.

VAV-dampers and constant pressure dampers

All dampers in CADvent can be motorized and controlled by flow or pressure. The motorization is shown with a 3D motor object attached to the damper.

Make a damper motorized 1. Select properties. 2. Select the damper(s) 3. Go to the Flow controller tab 4. Select regulation method. 5. Set data for flow and/or pressure 6. The motor is shown in 3D

Calculation with VAV dampers

Set fixed fan pressure When calculating VAV-system it is normal to keep the fan pressure constant. This is done in the dialogue of the calculation by checking the “Allow pressure > dp” and setting the fan pressure in the Available pressure edit box.

Calculation

When data has been set according to the previous sections the calculation method in CADvent can start to work. CADvent uses the data on the dampers to control the flow “below” the dampers in the system. It is now possible to see the resulting noise levels when a damper starts to close to keep the flow set on the damper. This can be presented either in:

- the calculation report - text information in the drawing - the analyze tool

VAV functionality on diffusers

As with the dampers the diffusers can be motorized and control the flow in the room. Normally these diffusers have a damper in the same branch that sees to that the pressure level is almost equal to all diffusers. The diffusers works so that the air flow velocity is kept constant independent of the flow and the pressure over the diffuser is also constant.

Selecting a VAV diffuser 1. Select VAV diffuser from the

component file via Comfort Express.

2. Set flow 3. Set working pressure as dP min 4. Insert diffuser

Make the diffuser motorized

1. Use properties to set the Damper state to: Fixed damper flow or to set the Damper state to: Fixed damper state

2. Set the minimum pressure to the configured pressure level for the diffuser

“Flexible connections settings” dialogue

Insert branch damper

When the VAV diffusers have been connected to the system insert a branch damper to control the available pressure to the diffusers. If there isn’t any damper the flow distribution will not be correct.

1. Find out the pressure level for the damper from the diffusers pressure levels + the pressure drop to the place of the damper position.

2. Calculate the small system to see to that you don’t get too much difference in between the rooms. If there are large deviations the flow will not distribute correct.

3. Insert the damper 4. Make it motorized by setting the

Damper State to: Fixed damper pressure and entering the pressure level.

Rotation of diffuser box It is often needed to separate the rotation of the diffuser plate from the rotation of the plenum box of the diffuser.

Rotate 1. Insert diffuser with box and

rectangular diffuser plate. 2. Click on the diffuser 3. Select the Grip point on the diffuser

plate side 4. Rotate the Grip point around the

diffuser

Connectors and short duct exchanged to SMFU

At the installation site the time to cut the ducts to fit the installation space takes a lot of time. It is always a strive to use as many standard length ducts as possible but there are often places where we are left with a short piece. There are telescopic products that can switch out the short ducts and the connectors. In CADvent there is a command that helps you to do this.

Cut the ducts in standard length

1. Use the connector command 2. Select the circular standard length 3. Select to insert duct to duct

couplings

Replace the short straight and couplings

1. Select the Insert sliding connector command

2. Select objects 3. Short ducts and couplings are

replaced
