Introduction of Eco-efficient Split Type ACs with R-290 in Costa Rica

12/2020 , Publication - Technical Publication :

As the primary source of direct emissions in the refrigeration and air conditioning (RAC) industry, the right choice of refrigerant is crucial to reduce global warming. 
This publication aims to inform about the implementation of eco-efficient air conditioning systems using the natural refrigerant R-290 in the Costa Rican market.

By implementing systems using the natural refrigerant R-290, Costa Rica is reducing greenhouse gas emissions and promoting energy efficiency. 

R-290 has a Global Warming Potential (GWP) of only 0,072, while for example R-134a, one of the most used HFC refrigerants in split ACs, has a GWP of over 4000 (numbers updated 2021, according to IPCC’s 6th Assessment Report; 20 years time frame). This comparison only emphasizes the importance of the transformation from synthetic to natural refrigerants.

In this publication the transformation process is being described, using efforts such as R-290 air conditioning systems or the implementation of training programmes for technicians. 

Please note that the publication is only available in Spanish.
