Advanced Airflow Solutions have been awarded the contract to supply grilles & diffusers to the Strand Palace Hotel in London's West End.
The Strand is more than just a busy London thoroughfare. Running parallel the Thames and connecting Westminster to the City, it has been a focus for political and financial power for centuries. Somerset House, a few minutes’ walk from the hotel, is just one of the noblemen’s residences that once lined the street.
For the majority of applications for air control in commercial buildings, it is recommended to select a regulator that handles a maximum volume equal to 6-8m/s velocity across the flow grid. The minimum controllable volume will be 1.5m/s and therefore a turndown to 20% will be achievable.
Some specifications call for a turndown to 10% of maximum; this would require that the maximum velocity is 13m/s, which would risk excessive regenerated noise.
Variable volume boxes having integral attenuators are designed with an internal geometry which reduces the velocity through the attenuator by a factor of circa 2.5 to 1.
When selecting stand alone regulators, either circular or rectangular, note that any adjoining attenuator will require a maximum velocity of 4m/s which means either limiting the maximum velocity through the regulator and thus limiting turndown to 2.5 to 1 or allow for a transition piece between regulator and attenuator.
Occupancy levels in modern buildings are increasingly variable, which has a significant impact on the prevailing internal load.
In addition to providing instantaneous local control, the VAV system, including air handling plant, chiller etc can be selected based on the number of occupants in the building at any particular time rather than on the sum of the individual zone maximums. This "maximum simultaneous load" approach can reduce plant sizes by up to 30%.

Advanced Airflow Solutions have been awarded the contract to supply Klimaoprema PDI diffusers to the Greenwich Peninsula development.
As part of our new range of products from Smartemp, we would like to introduce the new floor outlet type ISF-AD.
This inductive floor twist outlet can handle up to 48 l/s with a plenum pressure of 20Pa, making it ideal for upflow systems serving offices, dealer rooms and call centres. By using these outlets the system is able to offset cooling loads of up to 200 w/m2 whilst maintaining low room velocities and uniform temperature profiles.
In terms of energy efficiency, the upload system stands alone in its supremacy due to;
a) High supply temperature, 18°C, therefor reduced chilled capacity.
b) Low system pressure, slow SFP's.
c) When combined with variable volume supply, reduced air handling plant size.
The ISF floor outlet itself has been designed to include the option of a rotary "offset" plume or uniform plume contained within the same diffuser top, thus increasing the abolity of the system to accommodate changing furniture layouts.
The ISF also has the option of a motorised damper, making it possible to isolate areas or rooms which become unoccupied.
The outlets are available in polycarbonate and aluminium. Download the product brochure here.
We at Advanced Airflow Solutions pride ourselves on our ability to provide first class system design guidance and product application and would be pleased to assist with your current and future air distribution projects.
Advanced Airflow Solutions have been awarded the contract to supply Klimaoprema Slot Diffuser and Swirl Diffusers to the ten storey Atlantic House building in London which is home to international law firm Hogan Lovells.
The renovation of their 640m² office space is due for completion in April 2018, with the cleanroom specialists looking for an innovative yet cost effective solution.
The origin of the development of the Invisible Diffuser from Advanced Airflow Solutions was to find a product for use in clean spaces which provided high induction supply whilst maintaining a ceiling surface that is free of smudging.
Conventional high induction outlets which rely on a twist or pulse discharge allow dust laden room air to come into contact with the surface of the ceiling before it is induced by the high velocity supply. This rapid change in direction spins the dust particles out of suspension and deposits them on the ceiling surface resulting in unsightly smudging and revealing the position of the diffusers.
Claus Schweinheim, managing director of HT Lab Tec GmbH said "With the installation of the Invisible Diffuser the idea of HT to combine of a state of the art design with modern ventilation technology has been achieved."Read more
Advanced Airflow Solutions have been awarded the contract to supply Smartemp grilles & diffusers to the BBC Wales development in Cardiff.
The technical fit-out will begin in April 2018 and is expected to take around 18 months. BBC staff will begin the move to the new building in the autumn of 2019 and it will be fully operational in 2020.
Advanced Airflow Solutions have worked closely with our new supplier, Smartemp to develop highly technical solutions for the acoustically sensitive areas which has involved extensive testing in the Smartemp laboratory. The project features bespoke multi radial outlets, inductive sidewall (type PMW) and ceiling outlets (type HSC-FD) from the Smartemp range.
Advanced Airflow Solutions are pleased to announce our new partnership with Smartemp, manufacturers of high quality, highly innovative air distribution products.
The founders of Smartemp have been longstanding developers of bespoke and technically sensitive air distribution equipment. A summary of the Smartemp product range can be found here.
This exciting addition to our existing product portfolio means that we can now offer a full range of high quality, high induction and displacement outlets to cover commercial offices, auditoria, exhibition halls, sports halls, airports and factories.
Our partnership with Smartemp was given an early boost by securing the contract to supply adjustable thermostatic swirl diffusers to the prestigious V&A Museum in Dundee.
As always we are pleased to provide technical advice on system design and product application either directly or via our team of highly qualified sales agents.Read more
Advanced Airflow Solutions have been awarded the contract to supply Klimaoprema Slot Diffuser to the Walsingham House development in London.
The £21million development will see a radical transformation and upgrade as contractors carefully demolish the interior structure of the building, whilst retaining the attractive Portland stone façade. New piled foundations will enable the construction of a steel frame structure, adding two additional floors to the existing eight-storey building and creating nearly 50 per cent more internal office space to provide a net internal area of 65,000 sq ft.Read more
Advanced Airflow Solutions have supplied Smartemp HSC-AD thermostatic adjustable diffusers to the prestigious V&A Museum in Dundee. In a development worth over £80m, Scotland's first design museum is the centrepiece of Dundee's £1billion regeneration project which is forecast to attract hundreds of thousands of tourists and millions of pounds of investment to the city.Read more
