Review and understand mechanical systems

00:04

An integral part of creating and managing content for mechanical systems. In rev

00:09

is understanding system connectors.

00:12

System connectors will determine the type of systems

00:15

that can be created within your project.

00:18

And the configuration of those connectors will

00:20

determine the system behavior and the associated information

00:26

ensure the current view is set to H VAC floor plans. One mac,

00:33

the mechanical system shown here are six air terminals and a fan core unit.

00:38

And together they create a supply air system

00:42

by selecting an air terminal.

00:43

It can be determined which type of system it can be connected to

00:47

and the direction of flow.

00:50

This air terminal can be connected to a supply system.

00:53

The flow direction of the connector is in

00:56

and the connector size is six inches.

01:00

This air terminal can be connected to an exhaust or extract system.

01:04

The flow direction at the connector is out

01:07

and the connector size is 12 by 12 inches,

01:12

select one of the supply air terminals from the completed system

01:16

and note the flow rate is set to 120 cubic feet per minute.

01:23

All of the air terminals in this system are also set to the same flow rate

01:27

that equates to a total flow rate of 720 cubic feet per minute.

01:34

Select the fan call unit.

01:37

And a review of the properties shows the total flow rate

01:40

for all air terminals is calculated at the supply airflow parameter.

01:46

This indicates that while the flow of air goes in one direction,

01:50

the flow of data goes in the other

01:53

to understand the relationship between the air terminals and the fan call unit.

01:58

We need to review the connectors and the connector

02:00

configurations in the family editor for each item,

02:05

select the air terminal and then select edit family from the ribbon,

02:12

select the connector found on the air terminal family.

02:15

And let's take a look at some of the key properties that control the air terminal.

02:20

Firstly,

02:21

the system classification parameter determines this air terminal

02:25

can be connected to a supply air system

02:30

and the flow direction is sent to in at the

02:32

connector as the flow of air enters the air terminal,

02:39

the flow configuration parameter is set to preset.

02:42

This means that in use, the flow rate will be set at the air terminal by the user.

02:49

The radius of the connector is associated with

02:52

a parameter that controls the duct size.

02:55

So that while in use, if the spigot size of the air terminal increases,

02:59

so will the connector size.

03:02

Finally,

03:03

the pressure drop and flow parameters are also associated with family parameters

03:09

set up. In this way, both values become editable from within the project by the user,

03:16

the flow rate to suit the situation

03:18

and the pressure drop as determined by the manufacturer

03:22

close the air terminal without saving.
