The continually diminishing CO2 efficiency equator was a hot topic at ATMOsphere Europe 2015. Several system manufacturers presented the methods by which CO2 transcritical system efficiency can be improved, with ejector technology taking the spotlight. According the several presenters the end of the so-called “CO2 equator” is in sight. + VIDEO
There is a bright future for enhanced CO2 solutions in hot climates,” concluded Hansen.
This technology has been around for more than 100 years; we’re not reinventing the wheel here,” said Funder-Kristensen
Efficiency doesn’t depend so much on the ambient temperature anymore,” said Funder-Kristensen, “This is very encouraging because it means the limit for CO2 basically disappears.”
Commercial refrigeration is in a very innovative period,” said Hafner.
Currently, supporting parallel compression with an ejector is state of the art,” stated Hafner, “though adding pressure lift is something new; we need to integrate air conditioning.”
The CO2 equator is moving…actually, it’s gone. We will see this in the US and Asia, I’m sure of it,” said Hafner confidently.
