Refrigerants
😌 Simple Design
Section titled “😌 Simple Design”Total Refrigerant Charge
Section titled “Total Refrigerant Charge”The reduction of the total quantity of refrigerants used in the buildings HVAC+R system.
Choose from pre-defined refrigerant charges, or input a custom value.
Refrigerant GWP
Section titled “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:
Choose from pre-defined refrigerant GWPs, or input a custom value.
