Application-Based Refrigerant Screening

Refrigerant Finder

Narrow a broad refrigerant list into practical candidates based on application, project type, region, GWP target, safety preference and system scale. The finder ranks likely candidates first, then shows the wider matching set for further engineering review.

How the finder works
01 Describe the system Choose the application and project type.
02 Set the priorities Add region, GWP and safety preferences.
03 Review candidates See Top Matches plus the full matching list.
This is a screening and research tool. A match is not equipment approval, legal authorization or confirmation of retrofit compatibility.

Find refrigerants for your project

Start with the application. The remaining fields improve ranking quality but can be left broad when you are still comparing technologies.

Choose an application first so the finder can build a meaningful candidate set.
Important: Results are ranked research candidates. Refrigerant selection still requires equipment-manufacturer approval, safety analysis, charge-limit review and verification of current rules in the target jurisdiction.

No refrigerants match every selected condition. Try a broader GWP target or safety preference. Do not relax a regulatory requirement unless the applicable rule actually permits it.
How to Read the Results

A shortlist, not an automatic refrigerant approval

The finder deliberately separates application fit from final engineering approval. A refrigerant can look attractive on GWP and still be unsuitable because of safety class, charge limits, system architecture, component compatibility or local rules.

Application comes first

Candidate refrigerants are first screened around real HVAC/R use cases such as split AC, food retail, chillers, mobile AC and industrial refrigeration.

Safety changes system design

A1, A2L, A3 and B2L options have different flammability and toxicity characteristics. Safety class is a design input, not just a label.

Region affects the shortlist

GWP limits and placing-on-the-market rules differ by sector and jurisdiction, so the same refrigerant can have a different long-term role in different markets.

Why the finder does not say “best refrigerant”

There is no universal winner. Lower GWP, nonflammability, efficiency, operating pressure, component availability, service practices and regulatory longevity can point in different directions. The tool therefore ranks candidates and explains trade-offs instead of declaring one refrigerant universally superior.

Reference Framework

Built around current refrigerant classifications and transition data

The candidate dataset uses established refrigerant designations and safety classifications, U.S. EPA Technology Transitions GWP reference values, and current European Commission refrigerant-transition guidance.

ASH ASHRAE Refrigerant Designations Refrigerant numbering and Standard 34 safety-classification framework. EPA EPA GWP Reference Table 100-year GWP values used for U.S. Technology Transitions. EU European Commission Alternatives Current lower-GWP and non-fluorinated refrigeration pathways.
