Devcco prepared this study to examine the feasibility of replacing the existing population of HCFC/HFC based air-conditioners in Malé and Hulhumalé, Maldives, with district cooling technology...
Left unconstrained, HFCs are projected to grow to as much as 19% of emissions of carbon dioxide by 2050. Such growth would offset in large part progress being made on other short-lived climate pollutants as well as carbon dioxide (CO2) mitigation itself.
Maldives is in a critical stage of transition in coming years out of current HCFC-based cooling technologies and in the current situation, the country is seeing growth in air-conditioners using HFCs.
Not-in-kind alternatives include vapor absorption systems, deep seawater cooling systems, tidal and other cooling systems, etc. in a district/community cooling configuration. These systems do not use conventional refrigerants, such as HCFCs, HFCs and HCs. They can use multitude of energy sources such as waste heat, steam, direct heat, electricity, etc. These systems are potentially more energy efficient and have an overall low carbon footprint. They appear to be prima facie appropriate candidates for replacement of HCFC/HFC based air-conditioners. Thus, this presents an opportunity to utilize a climate-friendly district cooling approach, rather than transitioning to high-GWP HFC technologies in the Maldives.
