REFRIGERATION and air conditioning engineers are not normally employed on the basis of their administrative capabilities. Keeping up to date with new technology is difficult enough without having to keep up with the mundane but vital service and maintenance paperwork that goes with it.

The banning of R11 forced engineers to look again at methods for flushing a system. Advanced Engineering technical director Colin Pratt warns against the temptation to cut corners.

THROUGH simultaneous variable control of temperature, humidity, fan speed and capacity, the latest precision air conditioning can typically provide operators with a 30% increase in system efficiency compared with previous generation close control systems, according to Airedale project coordinator Adam Yarrington.

IT'S an old refrigerant whose time has come again; the gas of choice for supermarkets that is being recommended for a host of other applications, writes Neil Everitt, editor of ACR News

ENVIRONMENTALISTS have come in for so much criticism of late that further comment from me might seem like kicking a man when he is down, writes Neil Everitt, ACR News editor.

AS A refrigerant with zero ozone depletion and negligible global warming potential, CO2 is expected by many to be the refrigerant of choice for many future applications.

As the dust settles on R22, ACR News asks A-Gas md Ken Logan what gases we may be relying upon in the future.

Will the development of phase-change materials lead to this technology being considered as an energy efficient cooling/heating option or supplement to conventional ac systems?

WHEN air conditioning engineer Simon Dawes of Total Environmental Network was crowned the 2009 UK Skillfridge champion in July, it was the culmination of six years' dedicated training in a job he just "fell into" after being denied an army career.

Have you noticed how people are becoming less likely to use their real name. Even in an age where people are increasingly likely to expose their most intimate details on websites like Facebook, there are others who are perfectly happy, even encouraged, to hide behind "user names" on web forums and the like.

IN MOST buildings, power and communications still depend on a complex lattice of copper wires threaded throughout the structure. Each one of perhaps hundreds of thousands of individual cables has to be routed and attached at either end by a human hand. The cost in materials, time and potential error is vast.

IN AN advisory paper to the European Commission, AREA has promoted the continuing use of HFCs, questioned the effectiveness of so-called "drop in" replacements for R22 and predicted a massive reduction in greenhouse gas emissions as a result of the F-gas regulations.
