Ben Bartle-Ross looks at when it is appropriate or even necessary to pressure test an air conditioning system.
As a trainer covering our complete range of air conditioning products, I am amazed at how many engineers I see coming through my training courses who have been told by an (often) older colleague that when they are servicing air conditioning, they have to put a pressure gauge on a system to ‘test the pressures’.
On the 1st October 2015 the SIRACH network (Sustainable Innovation in Refrigeration Air conditioning and Heat pumps) visited Newcastle University and the Joseph Swan Centre for Energy Research.
The event focused mainly on the opportunities, challenges and new solutions offered by district heating and cooling networks. It included technical presentations, an interactive facilitated group networking session and a tour of the Byker District Heating Site at Newcastle.
During warmer periods, air conditioners are pushed to the max, in order to keep their users cool and fresh. Unfortunately, HVAC systems have their limitations too and can quickly overheat if measures aren’t taken to prevent them running out of steam.
Installers of these units need to know how to handle overheating systems and take steps to ensure any damage is minimised. Below is a list of common reasons HVAC units overheat and how you can help stop them from occurring.
Tony Ellerker, from Blakes M&E Building Services, explains.
One of the most common reasons a building maintenance crew is called out is water damage from leaking air conditioning units. If dark spots have begun appearing on ceilings or walls then you can be sure there is a considerable amount of condensation built up in the system.
Fortunately, there are a few ways you can prevent the damage from ever reaching this stage. But first you need to assess where the leaks might be springing from. Below is a list of common leakage causes and the ways you can ensure they don’t become a major problem.
AC contractors should be aware of all the health benefits of air conditioning in order to counteract their often negative portrayal in the press, as Tony Ellerker of Blakes Building Services explains.
Air conditioning doesn’t have the best reputation. You only have to google something like “health risks air conditioning” to see an awful lot of scaremongering from various sections of the press on the subject, much of it unfounded or at least misinterpreted. As it stands, though, it’s somewhat understandable that your customers may be a little chary about installing a new AC system.
So what’s a good contractor to do? Well, the best approach is to combat negativity with positivity. If a potential customer has heard lots about how an air conditioning system may be harmful to them, your best approach is to come back with the ways one can be a positive influence. Here are a few key points worth memorising...
At the time of writing, Britain has just had its hottest July day on record and this has to be good news for the air conditioning industry, which seems to naturally grow every time a scorching British summer makes people think seriously of the merits of air conditioning.
By Ben Bartle-Ross, technical trainer at Mitsubishi Electric
Hopefully everyone in the industry has work coming out of their ears and cannot find enough hours in the day to cope with demand.
But we all know what a fickle mistress the British weather is and for those whose air conditioning business is constantly reliant on the vagaries of the seasons, is there a way of ensuring more consistent business throughout the year?
