The following table describes the attributes used by the Load Calculator modules:

Table 1. Load Calculator Attributes

Name

Description

Default Value

Flow

Volumetric flow rate of the media through the device.

0 l/s, gpm

Precision: 10ths

Minimum value 0.0. If Flow is less than zero, the module should use zero for the calculations.

Glycol Concentration

If Media Type is Water-Ethylene Glycol or Water-Propylene Glycol, this indicates the percent (in weight) of the glycol component in the mixture.

10.0%

Precision: 10ths

Minimum Value 10.

Maximum Value 90.0

Heat Cool Mode

Switch to change the sign of Load, such that a positive value of a Heating Load means energy added to the fluid and a positive value of a Cooling Load means energy removed from the media. Changing this causes the module to execute.

Cooling

Set Name: Heating/Cooling

Load

The calculated amount of energy added or removed from the fluid.

0 kW, MBtu/h if Heat Cool Mode = Heating

kW, Tons of Refrigeration if Heat Cool Mode is Cooling

Precision: 10ths

Media Type

The type of fluid used in the system. Changing this causes the module to execute.

Water

Set Name: Load Media

Temperature In

Temperature of the fluid entering the device.

0 °C, 0 °F

Precision: 10ths

Temperature Out

Temperature of the fluid leaving the device.

0 °C, °F

Precision: 10ths

Unit Set

System of units. Changing this causes the module to execute.

I

Set Name: Unit; SET
