Analytical systems are created in rev
00:07
it so that designers can assess load calculations, equipment selection,
00:11
sizing and system simulation.
00:13
At the earlier stages of a project.
00:15
Without the need to create a physical model.
00:18
In this project,
00:19
we will use the analytical systems feature in rev it as one of
00:23
the steps in performing a mechanical systems
00:25
analysis and create analytical water loops,
00:28
air systems and zone equipment.
00:31
We will look at the configuration options for each the hierarchy of the
00:35
analytical system and the interdependency between
00:38
each aspect of the analytical system.
00:41
Ensure the current view is HVAC 3D views 3D
00:48
to create an analytical system in rev.
00:50
Let's start by accessing the tools from the system browser
00:56
from the view tab of the ribbon, select the user interface, dropdown menu
01:01
and choose system browser
01:04
from the dropdown menu. In the system browser set the option to analytical systems.
01:12
The order in which the elements of an
01:14
analytical system are created is not important.
01:17
But there is some interdependency between the water loops,
01:20
the air systems and the zone equipment,
01:24
we will start by creating a water loop that will be assigned to chilled water
01:30
in the properties change the name of the water loop to CHW 01.
01:38
While water loops are undefined, there will be a visible warning display
01:44
to address this set the loop type in the properties to chilled water.
01:49
And also notice the default chiller type is air cooled
01:54
at this point.
01:55
The loop is satisfied and the warning gone,
02:00
change the chiller type to water cold and notice the warning reappear.
02:06
This is because a water called chiller will require a condenser water loop.
02:12
Go ahead and create another water loop. And from the properties name it CD W 01
02:21
and then set the loop type to condenser water.
02:28
Select the chilled water loop CHW 01 from the system browser
02:34
and from the properties set the condenser water loop to CD W 01.
02:43
Expand the water loop CHW 01 and see the condenser water loop is now
02:49
included and the warning against the chilled water loop CHW 01 has disappeared.
02:57
Next, we will create a new water loop that will be assigned to hot water.
03:03
From the properties name the hot water loop. LP HW 01.
03:10
Then set the loop type to hot water.
03:14
The next step will be to define an air system where we
03:17
will have the option to connect the analytical water loops previously created
03:22
from the system browser. Select add air system
03:28
from the properties named the air system A hu 01
03:34
as with a physical air handling unit. The component parts need to be defined
03:39
elements such as heating and cooling cores can
03:41
be connected to water loops previously created.
03:44
And other elements of the air handling unit will be defined
03:47
from a list of available options suitable for the equipment.
03:51
Set, the preheat coil for the air handling unit to electric resistance,
03:58
set the cooling coil for the air handling unit to chilled
04:01
water and use the chilled water loop CHW 01 created earlier
04:10
set the heating coil for the air handling unit to electrical resistance
04:16
and finally set the air handling unit fan to variable volume.
04:23
The final step in creating this analytical
04:25
system is to define analytical zone equipment.
04:30
Once the zone equipment is added, we will have the option to connect water loops,
04:34
air systems and also to determine the type and behavior for the zone equipment
04:40
from the system. Browser select add zone equipment
04:46
name the zone equipment. VA V 01,
04:52
review the energy analysis properties and set the
04:56
equipment type to variable air volume box,
05:02
set the behavior to one per space.
05:05
This will assume that each analytical space will have a VA V box
05:10
rather than one va V box serving all analytical spaces in a zone,
05:17
set the heating coil to hot water
05:20
and for ease. Set the heating hot water loop to LP HW 01.
05:27
Though additional water loops could be created if required,
05:34
finally set the air system to a hu 01.
05:41
A final review of the hierarchy shows the water loops,
05:45
air systems and zone equipment
05:48
and the interdependency between each.
05:53
Our analytical systems have now been created and will
05:56
form the basis of our ongoing mechanical system analysis,
06:02
water loops air systems and zone equipment.
06:05
The component parts of a physical system can all be created analytically and rev
06:10
it
06:11
saving time and providing the flexibility to consider various design options
06:16
by simply altering property values and
06:19
creating new analytical elements when required
06:23
analytical systems are created quicker than adding physical equipment,
06:28
air terminals and duct and piping networks and do not require
06:32
ongoing coordination reviews with other disciplines whenever a change occurs.
