Brave new world
AUSTRALIA’S REFRIGERATION AND
AIR CONDITIONING TECHNICIANS HAVE
ONLY JUST BEGUN
TO TAKE THEIR FIRST TENTATIVE STEPS INTO A WHOLE NEW WORLD OF FLAMMABLE REFRIGERANTS.
Sandra Van Dijk – Editor
THIS NEW LOW Global Warming Potential (GWP) landscape is a foreign place for most Cert III qual- ified technicians.
It hasn’t even been a part of their training up until now although that is set to change with the revised Cert III course ready to be delivered.
The revised course has addressed many of these skills gaps and includes the latest refriger- ants and technologies.
We’ve also seen the recent introduction of for- mal training for R32 which now has its own ac- credited unit of competency.
It’s time for technicians to play catchup and take the necessary steps required to become fa- miliar with these refrigerants.
Each refrigerant has its own unique properties and safety requirements.
This brave new world needs new skills to deal with an increased level of flammability and toxic- ity, not to mention higher operating pressures.
Many of the unique challenges associated with these new refrigerants and their application will be covered at this year’s CCN Live event. It’s an opportunity to speak to experts in an environ-
ment where there is always plenty of open dis- cussion and lively dialogue.
We work hard to ensure the CCN Live format encourages animated discussion in a supportive environment. We want participants attending the October 10, 2019 event to participate and more importantly, be inspired.
Early bird tickets are only available until Sep- tember 3 so book now at www.climatecontrol- news.com.au/live
In the meantime check out some of our special features in this issue dealing with natural refriger- ants. Turn to page 22 for some innovative chiller combinations, there are some real knockouts!
Plus one of CCN’s 2016 award winners, Scantec Refrigeration managing director, Stefan Jensen, presents an impressive case study that really makes the case for ammonia.
According to Jensen when an older HFC sys- tem is replaced with a transcritical CO2 (TC CO2) system the improved energy performance can be up to 20% depending on the jurisdiction.
But wait for it..he has an even better option. In- stall a Low Charge (LC) NH3 system and the energy savings are far greater. In fact, Jensen estimates the LC NH3 system beats the energy performance of the TC CO2 system by about 40%. Now that is a massive dif- ference and a very bold claim. Of course Jensen backs it up with detailed specific energy consump- tion figures that he recorded at a cold storage facil- ity in North Queensland. He presented the figures just last week at the International Congress of Re- frigeration event in Montreal, Canada. Turn to page 28 for all the details.
Until next month,
