Meet Diana Madra, Lead HVAC Design Engineer for Johnson Controls, Navy Systems.
Where did you study?
I studied Environmental Technology at the University of Technology in Wroclaw, Poland (Politechnika Wroclawska ), specialising in Air Conditioning and Heating systems.
What was your first job?
My first real job after graduating was providing sales support at a refrigeration equipment distributor in Poland.
Where do you work now?
Since 2007 I’ve worked for Johnson Controls, Navy Systems, in the UK.
A shaky economic climate has led many people to adopt a 'make-do-and-mend' approach to HVAC plant rather than investing in new equipment. In fact, says John Grenville, Managing Director of ECEX, there is a useful halfway house – retrofitting – which offers an ideal opportunity to improve a building’s efficiency relatively inexpensively.
A recent Fujitsu VRF VR II Heat Recovery installation by H & D Air Conditioning at Quadrant Systems helps to keep the flight simulation company flying high.
Anyone fortunate enough to have been in a flight simulator will know what a cool experience that is. As well as being used for ‘fun’ experience days though, flight simulators also have a more serious and vital role in training for both civil and military crews.
Flight simulation experts Quadrant Systems Limited have operated from their purpose built facility at Burgess Hill since their formation in 1994. Quadrant are active across the core areas of the Flight Simulation Industry serving a diverse and worldwide customer base both with the in-house Training Centre and the Design, Engineering, Maintenance and Relocation teams.
Will Hawkins visits bespoke air conditioning and air handling systems manufacturer, Weatherite, to see what makes this company so successful.
It must be good being a Weatherite customer. The 'Black Country Welcome' is probably one of the warmest in the industry. And that comes right from the top of the business from Weatherite's chairman, John Whitehouse.
John explained how he started the business in 1972 from 'humble beginnings' and how it evolved into the group today, which is designing, making, installing and maintaining heating, ventilation and air conditioning (HVAC) systems for retail and industrial customers. Weatherite has no products on its shelves. Everything it produces is bespoke.
Peter Dinnage of Climalife explains how it’s not just for Supermarkets
The use of Performax LT (R407F) has been well documented as a R404A replacement in supermarket applications over the last two years, however, it can work equally well in other applications such as food storage and food processing applications, where R404A would have been the refrigerant of choice for new equipment.
With uncertainty over where the proposed changes to the F-Gas regulations may settle, there are a number of reasons to look at alternatives to R404, especially for new equipment. The selection of refrigerant based on GWP can be a reason, as R404A has a value of 3922, whilst the GWP of Performax LT (R407F) is more than half at 1824.
However, energy efficiency and carbon footprint reductions are other important considerations.
