Whichever market sector David Garwood of BSRIA looks at, especially in London, he sees growth in the air-conditioning sector for the next three years.
Lindab’s Solus chilled-beam system has been chosen to deliver energy-efficient climate control for a landmark building in Sweden — the Round House in the Munksjöstaden district. Pairing Solus with renewable-energy sources such as free cooling and ground-source heat pumps can achieve energy savings of up to 45%. The system includes nearly 600 Solus chilled beams and the entire ducting system. Pascal VAV system are being used in areas where the heating load can change very quickly, such as conference rooms.
Climate Center claims to be the first distributor to stock the low-GWP refrigerant R32 in every branch — amounting to 45 branches nationwide. R32 is a single-component refrigerant with a GWP of 675, considerably lower than the 2088 for R410A. The investment coincides with Daikin and Toshiba launching R32 air-conditioning ranges.
The EC (electronically commutated) motors in Advanced Air’s horizontal fan deck have a chip developed by Nailor, the company’s American parent, which gives a pressure-independent unit and makes the fan-coil self balancing so that no commissioning is required on the air side.
Since their introduction to the UK in the 1970s, fan-coil units (FCUs) have provided air conditioning to thousands of commercial buildings. However, there is another option to consider, which delivers energy efficiency and, importantly, flexibility — namely the chilled beam. Yan Evans of Fläkt Woods explains why it’s time to move on from the FCU.
Despite being a relative newcomer to the air-conditioning market, VRF continues to make significant advances. Neil Wooldridge of Toshiba Air Conditioning takes up the story.
Laboratories with fume cupboards can benefit from demand-controlled ventilation — with major savings on the volume of air handled and conditioning it. Ian Thomas of Trox UK explains.
Facilities-management provider Cloudfm can offer a 10-year warranty on Mitsubishi Electric air-conditioning equipment managed on behalf of its clients. The service comes after Cloudfm became a business solutions partner with Mitsubishi, which enables it to offer an extended 7-year warranty. Cloudfm will underwrite a further 3-year warranty on all new equipment and parts for Mitsubishi Electric air-conditioning products in the UK
Active chilled beams are finding increasing use in office and commercial buildings. They use a variety of solutions for air diffusion, adjustability and efficiency. By combining these in a smart way and adding new thinking, the optimal chilled-beam design can be achieved. Professor Göran Hultmark of Lindab explains.
Hitachi’s RCIM FSN4 range of mini cassette air-conditioning units has heating outputs from 1.9 to 8.5 kW in a VRF system. The air panel has a new, simple and stylish design. Its dimensions have been reduced by 80 mm compared with the previous 620 mm square, so it can be installed into a 600 mm-square ceiling opening.
As part of the full structural reconfiguration and refurbishment of 33 Glasshouse Street in central London, AET Flexible Space is supplying underfloor air conditioning. The building has a Grade 2-listed facade and is being refurbished to form larger, open-plan floor plates and Cat A office accommodation on floors three to seven.
Trane’s Sentesis eXcellent range of air-cooled chillers use HFO R1234ze as the refrigerant, which has a GWP of less than one when used in this design. These chillers offer capacities from 500 to 1260 kW. Applications include data centres, hospitals, and large office buildings.
Refurbishment projects often require effective control of comfort conditions within strict aesthetic constraints. Rinus Groenewald of Unico explains why small-duct high-velocity air-conditioning systems can offer a discreet alternative to other solutions.
Toshiba latest generation of luxury residential air-conditioning systems are based on refrigerant R32, which has a much lower global-warming potential (GWP) than the commonly used R410A. The GWP of R32 is 675, compared to 2088 for R410A. In addition the charge of R32 can be 30% less than for R410A for the same cooling capacity.
In response to growing legislative pressure to use refrigerants with lower GWPs, Johnson Controls has made the decision to enhance its HFC product lines by confirming that all screw and centrifugal chillers (air-cooled and water-cooled) will be fully future-compatible with R315A. This refrigerant is an HFC/HFO blend and has a GWP of 631. It is suitable as a drop-in replacement for R134a, which has a GWP of 1430. It has a low toxicity and is not flammable.
The first installation of Carrier AquaForce chillers equipped with variable-speed inverter-driven screw compressors delivers air conditioning for two office developments at 1 and 2 New Ludgate in central London. The 30XAV 950 chillers are equipped with Greenspeed intelligence to help deliver excellent part-load performance.

The system includes nearly 600 Solus chilled beams and the entire ducting system. Pascal VAV system are being used in areas where the heating load can change very quickly, such as conference rooms.
The difference between a newly installed air-conditioning system working perfectly or not at all can be down to a methodical commissioning process, says Martyn Ives of Fujitsu.
Toshiba Air Conditioning recently joined forces with installer BL Refrigeration to host a 2-day training event at Toshiba’s new state-of-the-art training centre in Manchester. It was attended by staff from consultants Arup, Cogan & Shackleton and WYG, all based in Belfast.
Refrigerants have been an environmental issue for many years. Having dealt with CFCs and HFCs, the pressure now moves on to HCFCs, with R32 being seen as solution. Ken Sharpe reports.
The latest stage of the long-term programme to replace HVAC systems to improve energy efficiency at the aviation headquarters of GE Aviation involved the installation of Panasonic’s recently developed PACi range of indoor and outdoor units. Eight PACi Elite 14 kW units were installed outdoors, with four under-ceiling units and four wall-ducted systems indoors. A further 28 kW of PACi cooling technology has been installed in the factory. R410A is the refrigerant.

Mitsubishi Electric’s Scott McGavin looks at what legislative changes mean for building operators and manufacturers, and how improvements in design and controls are helping increase seasonal efficiencies and performance.
Unlike much of the world, the UK air-conditioning market was buoyant last year, but there might be a tough year ahead. David Garwood of BSRIA looks at the statistics.
Carrier UK has won an air-conditioning product of the year award for its Aquaforce 30XW-V water-cooled chilled. It was one of the ACR Today national air-conditioning awards for 2014, and the judges remarked that it was a ‘neat package with time-proven technology’.

LG Air Conditioning’s tablet-like AC Smart Premium controller can control up to 128 devices — including air conditioners, heat-recovery ventilation systems and air-handling units. The home screen of this 25 cm touch controller shows the current state of the system including how many units are running and how many are not running. It also shows what scheduled events are due that day and at what times — and if a unit is faulty.
Hitachi Air Conditioning Europe’s latest generation of Utopia IVX splits sees improvements across both the Premium and Standard models, which are available from 2 hp single phase up to 12 hp 3-phase.
Adcock Refrigeration & Air Conditioning has launched a campaign to highlight an issue of refrigerant legislation that could affect over half of commercial properties in the UK. It concerns the complete phase out of R22, which has a small ozone-depletion potential, after the end of 2014, so it will be illegal to use it for topping up and maintaining air-conditioning equipment.
Frigesco’s flash-defrost system for cold rooms and refrigerated cabinets has won an international award at Clean Equity Monaco 2014. The system uses a phase-change material to store heat rejected by the refrigeration system in normal operation and uses it to defrost evaporators without the need for additional energy.
