Insulation Specifications

Insulation is applied at Branch level by setting of the ISPEC attribute. There is currently one insulation specification, named /CADCHVACISPEC, available in the HVAC application. However, if a User Defined Insulation specification is required it will be necessary for the HVAC Administrator to create a similar specification in a CATA database:
new spec /MyISpec copy /CADCHVACISPEC rename /CADCHVACISPEC /MyISpec
The SPWL will have a PURP HVAC and the SPEC will have a PURP INSU.
The SPEC will have the MATREF set to a material in the properties database that has a valid material density.
The database structure for the insulation is as follows:
|
SPWL Purp HVAC |
|||||
|
SPEC Purp INSU Question TYPE Matref /MyInsulationMaterial |
|||||
|
SELE QUES TEMP TANS 'INSU' TDEF 'NONE' |
|||||
|
SELE DESC '1"' ANSW 24 MAXA 26 QUES PBOR TDEF 'NONE' |
|||||
|
SPCO /MyISpec/INSU25 MAXA 10000 CATREF /INSU25 |
|||||
|
SELE DESC '1.1/4" - For when in imperial units ANSW 29 -- for 30mm insulation MAXA 31 QUES PBOR TDEF 'NONE' |
|||||
|
SPCO /MyISpec/INSU30 MAXA 10000 CATREF /INSU30 Etc… |
|||||
The CATREF element also must exist and can be defined by the administrator:
SCOM /INSU25
PARAM 50
SCOM /INSU30
PARAM 60
By creating these Cats&Specs elements this means that:
-
Insulation Spec and thicknesses will appear on the Create Branch form.
-
Insulation weight will be used in weight calculations.
-
Insulation can be shown graphically by using IPARAM[1] in the catalog geometry. (Actually IPARAM[2] could also be used if required for 2 level insulation but the standard catalog has not included this in its geometry).
