PRAHA-II is a continuation of the process with specific goals that are aligned with the findings of PRAHAI. The two main findings of PRAHA-I are that, 1) there are viable alternatives at High Ambient Temperature (HAT) conditions which need optimized equipment design to perform and deliver the energy efficiency minimum requirements, and 2) that there is a concern about safety of the most flammable alternative refrigerants that calls for a special risk assessment model for the HAT countries.
