Creating physical piping networks has many advantages including quantification
00:09
coordination and of course being able to retrieve
00:13
and interrogate system information including flow rate,
00:16
velocity and pressure.
00:19
However,
00:19
modeling to this level can be time consuming and could be
00:22
unnecessary if your interest lies only in the system properties,
00:28
ensure the current view is set to H VAC floor plans. One mac,
00:34
the radiators shown in each of the rooms will be connected to
00:37
the existing supply and return pipes to create a heating system.
00:41
In this example,
00:43
we will add some of the radiators to the system using physical connections
00:47
and the remaining radiators using analytical connections,
00:50
reviewing the workflow and associated properties of each approach.
00:56
One radiator is already connected to the system and a review
00:60
of the mechanical flow properties in the pipe shows the corresponding values
01:07
start by using standard modeling methods to connect the float and return pipes.
01:12
For the first radiator in the system
01:14
note the connection height is at 18 inches.
01:18
In this example,
01:20
because of the layout, the connections are not too challenging,
01:23
but typically allowances have to be made for the size of the pipe,
01:27
the elevation
01:29
coordination with other pipes.
01:31
And the fittings that will be included in the arrangement,
01:35
select the heating flow pipe at the boiler and note
01:39
the values in the mechanical flow area of the properties.
01:42
Here we see values have altered with the addition of a second radiator to the system.
01:49
Analytical connections for pipe in networks provide a quick
01:53
and easy way to create the final connection to equipment
01:56
without having to consider the potential complexities of routing pipework.
02:00
But they still provide the same information as a physically connected network.
02:06
Start by selecting the heating flow pipe at the second radiator
02:11
from the ribbon, select analytical connections
02:14
and then select the second radiator in the system
02:17
and note the changing color for the radiator.
02:20
And the analytical connection displayed here as a single line,
02:25
selecting the analytical connection
02:27
displays its instance properties
02:30
and choosing edit time allows the pressure drop to be set.
02:36
The heating return pipe can be connected to
02:38
the same radiator also using analytical connections.
02:44
A review of the mechanical flow properties in the pipe shows the values have again
02:49
altered with the additional radiator which this
02:52
time has been connected using analytical connections,
02:55
select the boiler
02:57
and see the total water flow value for the system
03:01
to complete the system.
03:03
Select the heating flow pipe,
03:06
choose analytical connections from the ribbon
03:09
and pick each of the remaining radiators
03:15
once complete,
03:17
the analytical heating return connections can be made in the same way.
03:25
Analytical connections provide a quick and
03:28
efficient method for creating mechanical piping networks
03:32
can be used with the pipe sizing tools in rev.
03:35
And they provide all of the relevant engineering data
03:38
used to validate design decisions and drive change.
