Total Refrigerant Charge
The reduction of the total quantity of refrigerants used in the buildings HVAC+R system.

Refrigerant GWP
The average global warming potential (GWP) of refrigerants used in the buildings HVAC+R system. Throughout C.Scale, three options are given for specification-related options: High Carbon, Average, and Low Carbon. Typically, these refer to the 80th, 50th, and 20th percentile of GWP values for available materials. We were unable to replicate this methodology for refrigerants, though, as the overall distribution of refrigerants skews very high–and this highly skewed distribution doesn’t represent the choices designers are making on their projects. In the refrigerant model, these three choices are keyed to specific refrigerants as follows:

🤓 Detailed Editing
The Refrigerants Configurator is designed to support the input of more detailed, project-specific data.
To begin using this feature, turn on Detailed Design within the Refrigerant accordion, and then click "Configure Refrigerants".


You can configure refrigerants using the following fields:
Count
The quantity of equipment.
Equipment Type
The type of equipment, which determines the refrigerant leakage rate.
Charge
The refrigerant charge associated with the equipment.
Refrigerant Identifier
The type and purity of the refrigerant included in the equipment.
Refrigerant GWP
The GWP of the refrigerant identifier.
Refrigerant Type
The chemical composition of the refrigerant identifier.
ASHRAE Safety Class
The ASHRAE safety class of the refrigerant identifier, which denotes the toxicity and flammability of the refrigerant identifier.
