Ben Bartle-Ross, a trainer at Mitsubishi Electric, looks at what the introduction of R32 systems means for air conditioning installers.
I was pleased to get some comments on the ACR Journal website in response to my previous post about R32.
However, I am not going to answer them here because I think the subject of R32 and safety is more than adequately covered by the F-Gas Regulations which are in place for a reason. It’s also why you have to qualify to handle refrigerants. Like just about anything in modern life there are dangers involved, but with correct training and handling, we seek to mitigate the risks and minimise the danger.
Reducing energy consumption remains high on the agenda for our UK food retailers, not just to meet obligations under the Carbon Reduction Commitment Scheme, but also to reduce costs in an increasingly competitive retailing sector.

Over 250 people from no less than 31 countries took part in the 12th International Institute of Refrigeration Gustav Lorentzen Natural Working Fluids Conference in Edinburgh in August this year.
The event, organised by the Institute of Refrigeration, attracted a higher than usual number of student delegates 52 of presenters and attendees were young researchers, students or engineers new to the industry.
Andy Pearson, IOR Technical Committee Chairman and Chair of the Conference, remarked:
“I was impressed with all the students that attended. Currently, refrigeration is an area where problems are becoming more difficult to solve and it is great to see the students beginning their journey and participating in tackling these issues.
Say hello to the latest member of the ACR Journal, namely our virtual friend, Captain Cooling!
You are going to see him in the journal, on our website and e-newsletters helping to point out events, competitions and opportunities for readers.
What's his back-story
Captain Cooling is a man of mystery right now. We need your help in working out who his arch-enemy might be and his weakness.
We know he hates inefficiency and poor standards. He loves helping tough, hard-working air conditioning and refrigeration engineers and professionals. Let the ACR Journal team know your ideas about his nemesis and we will design more characters for Captain Cooling to form alliances with, and to battle against.

If you have not noticed the 'Brexit' result from the EU Referendum last week, where the hell have you been?
The outcome has raised more questions than it has answered, such as 'Now that you have won, what's your plan?'. For the air conditioning and refrigeration industry, questions about the rules and regulations we have to follow are bound to be raised.
Who expected a Brexit vote? Clearly, not many expected the UK to vote to leave the European Union. But, here it is.
Businesses of all sizes should be thinking about taking on apprentices now.
Not only is Government funding available that will cover two thirds of the training costs, but there is a completely new industry-led Apprenticeship programme coming on board that is designed to ensure trainees have the skills to deal with both today’s and tomorrow’s industry needs.
Let’s face it, the air conditioning, refrigeration and heat pump industry is male dominated. And, trying to encourage more women into the industry can seem like a struggle at times.
That’s why we started the Women in ACR series, to show that there are more women in our sector than people may think. The articles also show how diverse those women’s roles are in the ACR business.
Now, working with the Institute of Refrigeration, there is a new networking group for women to enable easier networking, sharing of ideas, learning and mentoring. It’s called ‘Women in RACHP’.

By the time you read this, the referendum to remain or leave the European Union will almost be upon us and, whilst I am not here to persuade you one way or the other, I think there is no doubt that whatever the result, it is likely to have an impact of some sort on our industry.
On the one hand, you can argue that our industry suffers from too much red tape and perhaps leaving the union will free us all from bureaucracy – or will it simply take us back to a more unregulated, less safe industry?
Of course, that’s a stupid question. Leak detection is important and it matters. Most air conditioning or refrigeration systems will leak at some point in their lifetime. Some systems leak all the time.
Detecting where the leak is in the system can be a challenge. There are plenty of signs to show that a system is leaking (e.g. pressure drops, decreasing efficiency or, perhaps, the smell). To find the leak there are simple methods (e.g. soapy water), handy methods (e.g. handheld detectors), chemical systems and highly sophisticated methods (e.g. infrared). All are valid and have their pros and cons.
In addition, the EN378 legislation (Refrigerant Leak Prevention and Minimisation) is still evolving but it is close to completion. Unsurprisingly, EN378 has become a top topic on the ACR Journal website (see article here).
And, the debates continue on which is the best solution or approach to preventing and curing refrigerant leaks.
Which refrigerant leak detection and prevention methods do you use?
