Heating and Cooling Properties

These properties also list properties common to Inline Equipment including dampers, silencers, filters, heaters and coolers.

Property Name Description
Air Intake Diameter Positive <numeric value>
  • Sets outside diameter (D1) of Air Intake connection at End1.
Air Intake Length Positive <numeric value>
  • Sets the straight connection length (L1) at End1.
Air Intake Side Offset Positive <numeric value>
  • Sets offset distance between End1 connect point and side of box. Minimum offset equals radius of Air Intake.
Air Intake Top Offset Positive <numeric value>
  • Sets offset distance between End1 connect point and top of box. Default offset equals radius of Air Intake.
Auto Size s
  • Sets End1 equal to End2.
box <numeric value>/<numeric value>
  • Sizes device by solving equations: Body Width=W1+<first numeric value> and Body Depth=D1+<second numeric value>
endsequal
  • Confines the device to have equal size connections at each end.
Separate combined entries with semi colon.
Body | Depth Positive <numeric value>
  • Sets box depth independent of End1 and End2. Limited by Auto Size property.
Body | Length Positive <numeric value>
  • Sets overall length.
Body | Width Positive <numeric value>
  • Sets box width independent of End1 and End2. Limited by Auto Size property.
Cell Library <cell library file name>
  • Library file name for device cells.
Cell Symbol Name <cell name>
  • Sets the model cell to the device.

Prerequisite of proper Cell Library for AHUs.

Connection 1 | Length (L1) Positive <numeric value>
  • Sets straight length at End1.
  • Sets connection length at End1.
Connection 2 | Length (L2) Positive <numeric value>
  • Sets straight length at End2.
  • Sets connection length at End2.
Connection | End Type fl -<numeric value>
  • Sets and sizes end with a flange connection.
m -<numeric value>
  • Sets and sizes end with a male connection.
fe -<numeric value>
  • Sets and sizes end with a female connection.
Separate End Type entries for each End Spec with a semi colon.

Example: fl-2;fe-.13 creates a flange at End1 with size 2, and a female connection at End2 with an overall reduction of component's dimensions of .13

Gas Inlet | Diameter Positive <numeric value>
  • Sets outside diameter of Gas Inlet.
Gas Inlet | Side Offset Positive <numeric value>
  • Sets offset distance between Gas Inlet connect point and side of box.
