Cooling tower: Equipment Tab

Variable Definitions, Ranges and Default Values

The following table shows the meaning of the variables appearing in this tab, as well as their default values and their generally acceptable range. Note that due to the manner by which the variables are used by the sizing and costing equations, the range of acceptable values may be further reduced.

Variable	Default Value	Range

◙ Tower Floor Area The total area of the tower floor.	0.0 m²	Positive
◙ Max Tower Floor Area The maximum tower floor area that a unit of this type is available for purchase in the market.	30.0 m²	Positive
◙ Packing Height The packing height of the air inputs of the tower.	0.0 m	Positive
● Packed Volume The total packed volume.	0.0 L	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Sizing: Design Mode

In Calculate (Design Mode), the user specifies the Maximum Tower Floor area and the system computes the Number of Units, the Height, and the Tower Floor Area. See also Cooling in a Cooling Tower: Modeling Calculations.

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units, the Height, and the Tower Floor Area.

Costing

Equipment purchase cost is based on the total floor area and the packing height of the cooling tower. It is supplied by the built-in model assuming as material of construction SS-304.
