Interrogate system information with the system inspector

00:03

Color fields can be used to great effect for more

00:06

easily identifying ongoing changes and issues with mechanical systems.

00:11

And with the spaces in which they are located

00:15

systems analysis tools such as the system inspector and the system

00:19

browser can also be used to interrogate information within a system

00:23

that could be considered a more flexible approach as they are not

00:27

restricted to only displaying the values for one parameter at a time.

00:32

In this example,

00:34

we will use the system inspector to interrogate and identify issues in a system,

00:39

make changes to that system.

00:41

Then use the system inspector again to verify the outcome.

00:45

We will configure and use the system browser to locate systems and elements,

00:50

then verify data and monitor changes in a system.

00:55

Ensure the current view is set to H VAC floor plans. One mec

01:02

the system inspector is a contextual tool that only

01:05

appears when a section of duct or pipe is selected

01:08

and may not appear at all.

01:10

If there are issues with the system, you plan to interrogate,

01:14

select a section of duct from the system FCU 04 supply

01:19

and from the ribbon, select the system inspector

01:23

then from the system inspector panel select inspect

01:28

an initial review of the system shows that the direction of flow is correct.

01:32

But let's take a look at the system in more detail,

01:36

the red arrows to air terminal 24 indicate the critical path

01:40

which should be to the air terminal furthest from the phone

01:43

call unit.

01:45

Continue to move your cursor across the system and

01:49

note the range of information available from the system.

01:51

Inspector

01:56

place your cursor on the air terminal at the end of

01:59

the critical path where the excess pressure value is zero,

02:03

then place your cursor against some of the other

02:06

air terminals in the system and note the higher values

02:10

at a later stage.

02:11

These excess pressure values can be used to set the value of dampers in the system.

02:19

Close the system inspector and use the split element

02:22

tool to create a break in the duct.

02:24

After air terminals. 24 and 26

02:32

change the duct size for air terminals 24 and 25 to 8 inches.

02:44

And the duct size for air terminals 26 and 27

02:48

to 6 inches.

02:57

Use the system inspector again

02:59

to check the critical path and the excess pressure value at air terminal. 27.

03:11

Finally

03:12

placing dampers at the other branches and setting the pressure drop value in line

03:17

with the excess pressure at the air terminal will effectively balance the system.

03:25

Place a round damper in the duct at air terminal 23.

03:33

Check the properties and change the value for pressure drop to zero.

03:41

Use the system inspector to check the excess pressure value at air terminal 23

03:52

close the system inspector then change the pressure drop value for the

03:57

round damper to match the excess pressure value at the air terminal.
