Positive indications for the future? David Garwood.

Gauging trends in the UK air-conditioning market

Focusing on project-completion trends in 2016 provides evidence for what drove sales of large commercial air-conditioning products such as VRF and chillers and explains why there was only marginal growth, as David Garwood of BSRIA explains. He then gives an outlook for the years ahead.

Advanced Air, FCU, fan-coil unit, air conditioning

Fan-coil units come pre-commissioned

Advanced Air can now deliver fan-coil units that are pre-commissioned in the factory with the setpoints for water and airflow established so there is no need for any on-site commissioning. The company has entered into an agreement with Belimo and Advanced Air’s control specialist to design and develop a simple EPIV/Delta control package (EPIV is an electronic pressure-independent valve).

Panasonic, VRF, air conditioning

Panasonic equips Heal’s refurbishment project

Cooling and heating for the refurbishment of the Heal’s building on London’s Tottenham Court Road to provide offices over five storeys is provided by the Panasonic ECOi VRF system. Occupants include companies such as Netflix and Deliveroo. Consultants Cundall worked with Easy Air Conditioning to design and install the system.

Toshiba, warranty, air conditioning

Toshiba breaks new ground by managing warranties online

Toshiba has developed an online commissioning and warranty system for air-conditioning installations which will deliver significant cost and time benefits to end users, installers and service companies. It is administered by Toshiba, and customers and installers can log onto the system from a smart phone, tablet or PC to access comprehensive data on installed equipment at individual plant or building level right up to a national estate.

Long-lasting efficient operation — Brent Hall

Top 6 water-treatment tips for lasting chiller performance

Chillers are the backbone of commercial and industrial cooling systems across the country. However, they are not a ‘fit-and-forget’ solution, Brent Hall of ICS Cool Energy highlights some easy ways to look after a chiller to ensure it lasts 10 years and more and performs as efficiently as possible.

The logical refrigerant for the future — Carl Dickinson.

Why R32 refrigerant is the intelligent choice

Not only is the global-warming potential of R32 much lower than the refrigerants it is designed to replace, but a smaller charge is needed — two wins for the price of one refrigerant. Carl Dickinson of Mitsubishi Electric discusses why R32 is the logical fit for the HVAC industry.

Fan-coil remote display module

Among a series of fan-coil designs from Advanced Air is a remote display module (RDM). It is mounted on the cover of the control box for easy access without having to remove screws or bolts. Commissioning is made much easier, and the fan coil can be commissioned without the BMS being completed. It also provides a cross check between what the BMS is displaying and what is actually happening within the fan-coil unit.

Maximising heating performance — Neil Wooldridge.

Taking control of frost build-up

The build-up of frost on the outdoor coils of air-conditioning systems in heating mode can interrupt the provision of heating and use a significant amount of energy to melt it. Neil Wooldridge of Toshiba Air Conditioning explores the issue.

Coolair uses aluminium refrigeration piping for hotel renovation

Air-conditioning installer Coolair Equipment used Reflok’s aluminium piping and compression-jointing system to install a Mitsubishi Electric VRF system to provide heating and cooling for all 360 bedrooms of the Sheraton Grand London Park Lane hotel. This approach avoided the brazing operations association with copper tube.

Mitsubishi presents R32 Mr Slim at same price as R410A

Mitsubishi Electric is preparing to launch R32 versions of its Mr Slim range that will be available at the same price as the equivalent R410A units. R32 has a GWP (global warming potential) of 675, compared with 2088 for R410A, and the new Mr Slim units are also more efficient. The new range will be available from July 2017.

Johnson Controls, oil, air conditioning

Johnson Controls responds to counterfeit-oils issues

Johnson Controls has responded to concerns about a rise in counterfeit oils for compressors being placed on the market by offering a range of branded authentic York lubricants. Lubricants are a key component of chillers and mechanical cooling systems, protecting wear surfaces, ensuring long life, maintaining leak tightness and, not least, ensuring proper performance and efficient operation. They also play a vital role in reducing corrosion, which can quickly result in serious internal damage and/or mechanical breakdown.

Cooltherm, Mitsubishi, chiller, air conditioning

Retrofit chiller boosts efficiency for Cardiff Uni

Cardiff University has upgraded chilled-water air conditioning in one of its buildings with the installation of a Mitsubishi E-Series chiller by Cooltherm. The Cooltherm team in Wales designed a bespoke turnkey chiller plant to provide the most efficient and low-carbon system as possible.

Hitachi, VRF, air conditioning

Hitachi VRF controller avoids cold draughts

Hitachi Air Conditioning’s CS Net control system prevents the temperature of air from System Free indoor units used as part of a Set Free VRF system creating cold draughts in by not letting the air flow become too cool. This off-coil protection feature works with System Free indoor units which have an air-on thermistor, air-on thermistor, liquid thermistor, gas thermistor and electronic expansion valve.

Toshiba, VRF, air conditioning

Toshiba launches 3-pipe VRF system

The launch of Toshiba’s latest 3-pipe heat-recovery VRF air-conditioning system, SHRM-e, builds on the success of the SMMS-e VRF system, which had an ESEER (European Seasonal Energy Efficiency Rating) of over seven for all capacities. Developments in key technologies in the latest system include the compressor and intelligent control system — supported by incremental improvements in almost all system components. R410A is the refrigerant.

LG, air conditioning

LG Artcool units heat and cool home refurbishment

LG multi-split air conditioning provides the primary heating source as well as cooling in the warmer months of the year for the imaginative refurbishment of a Victorian detached home in the south of England close to the M25. Other features of the refurbishment include triple-glazed windows, condensing-boiler back-up heating system, underfloor heating downstairs and high levels of insulation. There are also solar panels on the south-facing roof.

Advanced Air, FCU, fan-coil unit, air conditioning

Advanced Air enhances its reversible FCUs

The universal truly reversible fan-coil unit developed by Advanced Air can have its handing easily changed in the factory or on site and now incorporates further refinements to speed up the process. Prewired looms for right-hand and left-hand mounting of the control box are included as standard. Push-fit connections ensure that electrical connections are easily and quickly made in production or when changing the handing in the factory or on site.
