PRAHA Methodology: Building and Testing Prototypes and Related Research

The core component of UNEP/UNIDO project for promoting low-GWP alternatives in high-ambient countries is building and testing prototypes by local OEMs with the support of several international technology providers. The presentation introduces the findings of the testing of the prototypes developed under the project for four different categories of air-conditioning applications using four different types of alternative refrigerants. Detailed background on the testing methodology, design limitations and the criteria for selecting the capacities, refrigerants and design parameters are included in the presentation. The presentation also reflects the technical challenges the project faced while building and testing the prototypes.
