Chillers


This month HVR launches its campaign to support the SAMARITANS in a drive address mental health in the Construction Industry. This, the first in a series of features to highlight the issue, exposes the scale of the problem and suggests how you can help!


The downside of being invincible


to provide a system capacity from 90kW to 540kW. For larger systems, it is also possible to have the units facing each other with a gap of only 900mm service space.


Innovative


What’s more, in a sophisticated approach, two compressors are used in a single chiller unit, with each compressor serving a separate plate exchanger – this is known as a two-stage cooling circuit. Overall system efficiency can increase by an additional 3.9% by modulating the evaporating temperature individually, compared to single evaporation refrigeration cycles. Not only that, it also allows the system to carry on operating in the unlikely event of a component failing within one of the two circuits. Modern chillers are also less disruptive on the ear, as fan blades have


improved ventilation characteristics and newly designed rear edges that suppress wind turbulence. This in turn, increases efficiency and reduces noise levels with sound pressure measured at just 65Db(A) in some instances.


New generation


Further advances in technology have led to a new generation of cooling only water chillers which can be easily integrated into the most complex of building systems. The majority of models are suitable for a wide range of applications including modern multi-function buildings, shopping centres and large business centres. Many chiller models on the market allow for bespoke application design for individual projects with different levels of efficiency and sound emission levels available. Furthermore, the latest state-of-the art-chillers are certified by the


Eurovent program which guarantees the highest reliability and quality to the strictest European standards. Mitsubishi Electric offers both air source and water cooled chillers across


two ranges – e-series and NX - which are energy saving and innovative with industry leading low-noise levels. To improve the energy performance of a building while meeting the legislative drive, chillers offer a perfect solution while keeping disruption to a minimum. The latest chiller technology optimises energy performance, with quiet, compact systems, that can be readily fitted into existing plant space, enhancing overall comfort for occupiers.

the UK, more than 6,000 people took their own lives last year. More than 75 per cent of them were men. Building trade workers are at higher risk than average. An ONS sur- vey, Suicide by Occupation, found manual workers in the construction industry are at 3.7 times greater risk of suicide. Some men find it difficult to be open about their problems and ask for help. Some don’t recognise the signs they’re at risk, and those around them often don’t ask. Samaritans ‘Men and Suicide’ re- port sheds light on why men find it harder to ask for help and speak about how they are feeling. Some men compare themselves against a gold standard of masculin- ity which values power, control and toughness above all. If they feel they are not coming up to scratch, men who believe this can feel shame, de- feat and despair. Asking for help is not something they can do easily as they see it as a loss of face. Suicide is also a social issue. Men

from the lowest social class living in the most deprived areas, are 10 times more likely to end their own lives than men in the highest social class. Middle aged men are the most at


risk. Other factors, such as unemploy- ment, being socially isolated, and re- lationship breakdown also contribute to their suicide risk. We need a concerted, national ef-


fort to raise awareness and provide support to make a difference and save people’s lives. Supporting work colleagues and promoting good men- tal health is a big part of this. The British Safety Council and Health in Construction Leadership Group has launched Mates in Mind (www.matesinmind.org) to promote wellbeing and resilience, raise aware- ness of mental health and suicide in

the building trade and find effective ways of supporting people. Samari- tans is a partner organisation. The reasons behind this unwilling- ness to ask for help are very complex, but the more people Samaritans can reach with the message that it’s good to talk about what you are going through, and get help early, rather than waiting until you hit a crisis, the more likely we’ll be able to tackle the suicide statistics. Here are some pointers that you


can look out for that may indicate that someone is struggling: • A change in routine, such as sleep- ing or eating less than normal. • Lacking energy or appearing tired. • Drinking, smoking or using drugs more than usual. • Finding it hard to cope with everyday things. • Avoiding things they usually enjoy. • Becoming withdrawn from friends and family – not wanting to talk. • Appearing more tearful. • Appearing restless, agitated, nerv- ous, irritable.


• Putting themselves down in a seri- ous or jokey way. • Losing interest in their appearance. Economic insecurity, the strains of self-employment, competition in the job market, zero hours contracts and low wages all take their toll in an in- dustry that can be punishing to be part of. Employers are increasingly recognising that they need to make a concerted effort to tackle this issue. Suicide is the biggest killer of men under 50, and it’s everybody’s busi- ness to look out for themselves and their mates. Simply asking: “Are you okay?” could be a positive step towards a more open and accepting attitude which could save lives.
