This document provides the results of a comprehensive assessment of the state of the art on the use of flammable refrigerants, in particular from class A3.
Refrigerants from class B (toxic) are excluded from this scope.
The Technical Report includes the following elements:
• A segmentation of the refrigeration, air-conditioning and heat pump market, making use of existing
studies and research, including an assessment of safety-related barriers to the uptake of flammable
refrigerants in particular from class A3 across all relevant applications;
• An assessment of the way risk assessments are used in existing standards for refrigeration, air-
conditioning and heat pump equipment and in other standards and a review of available risk
assessment research to be taken into account including identification of potential needs for additional
research;
• Analysis of:
o the relationship between risk and increased charge;
o the acceptability of increased risk compared to the risk presented by other technologies;
o the options for additional mitigation methods if the risk increase is unacceptable.
