UK to stage the 2017 international infrared users conference LIR Systems has
confirmed that this year’s ITC International User Conference will be held in Coventry from September 27th-28th, 2017. It is the opportunity for
technicians, engineers, scientists and users of all types of infrared measurement equipment to exchange ideas and explore the huge potential of the technology. The first ITC conference was in 2005 but it was very specialised, focusing on the use thermal imaging in the R&D environment. Over the years, as the
technology has broadened its scope, so too has the remit of the event. It is now a forum for everyone who uses thermal imaging in a professional capacity.
The 2017 event will cover infrared physics and its applications in a wide variety of fields from inspection of electrical installations and buildings, control and automation and optical gas imaging to non-destructive testing and advanced research applications.
Eurovent Association releases new air filter guidebook
Alan Green honoured at ACR News Awards
Consultant at Trox, former Chairman of the Chilled Beam and Ceiling Association (CBCA) and senior member of FETA, picked up the prestigious Alan Moor Award at this year’s ACR News Awards in recognition of his outstanding service and dedication to the industry. This year’s event at Chelsea Harbour Hotel attracted over 240 guests from around the air conditioning and refrigeration industry and was hosted by comedian Ed Byrne.
Dedicated to the late Alan Moor, former Managing Director of Bitzer UK, the Alan Moor award is presented to an individual whose efforts on behalf of the air conditioning and refrigeration industry have largely gone unheralded.
Alan Green first became involved with the HEVAC Group in September 1976 as an engineer with Trox Brothers. He soon became
lan Green, Technical
involved in various committees.
He was a lead figure in the production of the HEVAC industry standard, The Air Diffusion Guide, in 1982 and for the second edition in 1988 and he was the principle author when it was updated into the Guide to Air
Distribution Technology for the Internal Environment in 2000. He became a member of the BSI technical committee responsible for ventilation in buildings and in the early millennium became its chairman. He subsequently became chairman of the corresponding CEN European standards committee. Even though he retired from full time employment at Trox UK he stayed as a Technical Consultant and has
continued chairing both the BSI and CEN standards committees. He remains a key participant in the HEVAC Council, the Fan Coil Group and the CBCA.
he Chartered Institute of Plumbing and Heating Engineering (CIPHE) has welcomed Tim Sainty to the role of Membership Director. He joins the Institute from the British Veterinary Association (BVA), where he spent seven years as Head of Membership and a further 10 years within the organisation in various membership positions. Tasked with growing CIPHE membership, enhancing services for members and improving communications, Sainty will be playing an active, frontline role within the Institute.

Kevin Welman, CEO said: “Tim joins us at a very exciting time. The Institute is 100% committed to enhancing its benefits and services to members in the UK and worldwide. With Tim’s knowledge, experience and energy on board, we are looking forward to some really positive developments through the rest of 2017.”

Association’s Air Filters Product Group has released the first edition of its guidebook, ‘Air Filters for General Ventilation’. The new guide covers:
uThe importance of filtration uBenefits of using air filters uFundamentals of air filtration uStandards in place uCorrect filter design, uEnergy efficiency of air filters uKey applications for air filters uCorrect assembling, maintenance and disposal of used filters.
Specific attention is given to the new global ISO16890 air filter standard as well as the importance of air filters in
ensuring a healthy indoor climate.
Chris Howarth (Jasun Envirocare Plc, United Kingdom), member of the Eurovent Air Filters Product Group and Lead Editor of the new guidebook, said: “With air filters constituting a key factor in ensuring a better indoor air quality, the aim of our new guidebook is to provide users of our products with hands-on information to receive a better understanding of air filtration and what is behind this seemingly simple product.”
The Guidebook ‘Air Filters for General Ventilation’ is available free-of-charge at:
Sales Director appointed at Light Management Systems in Glamox
he management of the professional building solutions division of Glamox regards light management systems (LMS) as an area of considerable strategic interest and has recently established a new Sales Director role for LMS. Although such systems have been on the market for many years, the technological development, focus on environment and cost of ownership has made LMS a more lucrative investment in recent years. This is why Glamox now is investing more resources in this area.
“I’m very pleased to announce that Bjørn-Erik Askestad has accepted the position as Sales Director LMS in the PBS division with effect from April 3rd 2017,” says Senior Vice president PBS Division Knut Rusten.
Bjørn-Erik Askestad has been working as Manager for Projects and Customer Support for Micro Matic Norge AS, which is a Norwegian building controls company. Glamox Luxo Lighting is a leading supplier of lighting solutions to the professional building market in the UK, offering product ranges for schools, healthcare facilities, commercial and industrial buildings, retail facilities, hotels and restaurants.

HVAC applications, great care must be taken to ensure correct specifications are applied that support the eventual owner/operator, including lifetime considerations.
This is especially true as changes in building regulations result in the introduction of new technologies that may not be right for HVAC applications. Take
electronically commutated motors (ECMs). These are brushless DC motors that function using a built-in inverter and a magnetic rotor, and are highly efficient, providing a consistent airflow over a range of downstream static pressures. From start-up they provide a gradual ramp-up to set-point flow rate and generate less noise than many other motor
technologies. They are highly modular, helping with installation.
However, while ECMs achieve specific fan powers at smaller powers, they can generate large amounts of harmonic distortion. The motors cannot ride through power dips nor can the controller catch a spinning load, something that is critical in the HVAC industry, especially data centres. If a controller cannot catch a spinning load (usually after a power outage), then it has to bring the motor to a very abrupt stop before accelerating the motor back to the desired speed. This abrupt stop is likely to severely damage the

hen it comes to selecting motor technology for
mechanics of the fan, the couplings and its mechanics. Furthermore, if a system cannot ride through a power dip, then the controller will need resetting to bring it back to operation. Resetting takes time, and during that time the HVAC system is not operating.
While the ECMs may be suitable for some
applications, it is essential to consider the right motor technology. ECMs are limited up to 7.5 kW. Above that customers and OEMs should consider synchronous reluctance motors (SynRMs). These motors can achieve the specific fan powers, whilst being controlled by a variable speed drive (VSD). The benefits from using VSDs include improved harmonic mitigation, ability to a catch a spinning load, adequate power drip ride-through, fieldbus communications and built-in control features to enhance the application. SynRMs are built into a standard IEC motor frame, enabling quick and easy swap out during repair or replacement. In contrast, ECMs tend to be
application-specific and customised. This can require an entire fan or pump to be replaced if the motor fails. Lastly, SynRMs do not generate unwanted dangerous voltages when operating on a wind-milling fan. And being synchronous, the motors are easy to control accurately, even above nominal speeds where improved fan efficiencies can be realised. uTo find out more, sign up for ABB’s eBook on
