To comply with the HFC phasedown, organisations are seeking efficient systems that can also reduce indirect CO2 emissions.

The use of the highest-performance technology is essential for combining natural refrigerantsand high efficiency. There are several variables to consider: the unique characteristics of natural refrigerants, such as high pressures with R-744 (CO2) cycles and the flammability of hydrocarbons.

A new whitepaper by Carel’s HVACR technical knowledge specialist, Miriam Solana, brings together years of study and research into natural refrigerants.

“Our intention with this document is to contribute to making available as much theoretical information as possible, and providing an overview of the technologies for optimising energy savings and creating systems with the lowest total CO2 emissions,” she said.

“At CAREL we believe in the importance of supporting broad use of these refrigerants, which represent a concrete and feasible response to environmental sustainability.

“We need to continue to study and carry out research: the goal of innovation is to achieve systems that are compatible with the unique characteristics of natural refrigerants and in compliance with regulations, without sacrificing efficiency.”

 The natural refrigerants white paper is divided into five parts. The first provides a summary of the characteristics of natural refrigerants. The second examines the evolution of cycles with natural refrigerants and the possibilities that are currently available.

The last three sections describe examples of modulating technologies and high-efficiency solutions. The goal is to have an overview of the technologies available to design high-efficiency systems using natural refrigerants.
