“The aim of the Natural Refrigerants white paper is to systematically bring together the results of years of study and research into natural refrigerants,” said Miriam Solana Ciprés, HVAC&R Technical Knowledge Specialist at Carel, and author of the white paper.

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

The paper considers the unique characteristics of natural refrigerants, such as the high pressures with CO2 (R744) cycles, and the flammability of hydrocarbons.

The white paper has five parts:

  1. A summary of the characteristics of natural refrigerants.
  2. The evolution of cycles with R744, ammonia and hydrocarbons, and the possibilities that are currently available.
  3. High efficiency and modulating technologies.
  4. High efficiency refrigeration solutions with natural refrigerants.
  5. High efficiency HVAC solutions with natural refrigerants.

Carel believes in “the importance of supporting broad use of these refrigerants, which represent a concrete and feasible response to environmental sustainability,” said Solana Ciprés. The company offers a wide range of components for R744 systems and hydrocarbon equipment.

But Carel plans to continue its 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,” she said.
