The study showed that a system using R-410A achieved lower environmental impact during the entire life cycle of the fluid and the equipment, including power consumption, than a system using R-290 (propane). The LCCP analysis of R-410A was 4.2 percent lower than propane.
The 31-page study titled "Comparison of Hydrocarbon R-290 and Two HFC Blends R-404A and R-410A for Medium Temperature Refrigeration Applications" is available for free download at www.ari.org. The study is part of the Global Refrigerant Environmental Evaluation Network (GREEN) analysis of the relative performance potential of R-290 to two HFC refrigerants (R-404A and R-410A) for medium temperature commercial refrigeration under the auspices of the International Council of Air Conditioning and Refrigeration Manufacturers Associations (ICARMA).
Findings from the study include:
GREEN is a worldwide refrigerant evaluation initiative set up to test HFCs and other refrigerants such as ammonia, propane, and butane in air conditioning and refrigeration equipment and compare the results on an equal basis. GREEN's goal is to work collectively with refrigerant manufacturers, testing laboratories, and air conditioning and refrigeration trade associations from Europe, China, Japan, and Canada to measure refrigerant systems' performance while taking into account energy efficiency, cost effectiveness, practicality, and safety.
