Brazils rendezvous with Propane Presented by: Edgard Soares, - PowerPoint PPT Presentation

Brazil’s rendezvous with Propane Presented by: Edgard Soares, National expert, UNIDO July 16, 2020

Agenda • Key Stakeholders for Project Implementation • Project Goals • Companies • R-290 chillers / Installation • Barriers • Key Findings 2

Key Stakeholders for Project Implementation • Brazilian Ministry of Environment • UNITED NATIONS INDUSTRIAL DEVELOPMENT ONGANIZATION (UNIDO) • Multilateral Fund (MLF) / Montreal Protocol 3

RAC Montreal Protocol Project Goals in Brazil • HCFC-22 Phase-out in the retail sector; • Product with low impact to the global climate system ; • Safe conversion of the production line and the facilities; • Demonstrate current solution • Raise awareness in the supermarket sector. Solution: R-290 Modular Chillers 4

Companies Eletrofrio Plotter Racks Manufacture commercial refrigeration equipment ! HCFC HFC CO 2 R-290 5

Assembly Area Refrigerant handling package • Charge Machine • Leak detector • Vacuum pump • Tool for sealing process tube • Recovery unit for defective units Safety Measures • Ventilation • Sensors and alarms for R-290 • Antistatic painting or antistatic mat 6

Charging Area - Eletrofrio 7

Barriers identified for this technology • Liability • Flammability of R-290 • Uncertainty on skill level of service technicians • Cost: • Technical solutions to mitigate flammability risks has extra costs; • Main components imported; 17

Key Findings of the Projects until now • The R-290 modular chiller will help both companies to develop new solutions and NEW business models. • Improvement of energy efficiency • Systems require less maintenance • Reduced installation time • Safe place to assembly and maintain chillers in the factory. 18

Key Findings of the Projects until now • Refrigerant charge reduction • Do not require trained technicians in the field • Raise awareness regarding the advantages of using propane in refrigerating systems. • The adoption of the R-290 will limit the future use of synthetic refrigerant with high GWP • The project with Eletrofrio and Plotter Racks companies will result in 157.6 t of ODS elimination. 19
