air handling unit design

The Eco-design Directive or ErP (2009/125/CE) aims at reducing by 20% greenhouse gases emissions within the European Union by 2020 (greenhouse gas emissions have to be divided by 4 by 2015) by reinforcing energy efficiency on energy consuming products. This article was published in Galivel & Associes, 25th February 2016 (only in French):One Company from Design to Installation For over 30 years, Mallard have built quite a reputation in air handling. We're the brand of preference for many reasons. For some, it's the quality of the workmanship and finish giving assurance for longevity and reliability. For others, it's our British manufacturing base with technical support and assistance readily available. For many, it's the cost-effectiveness of the result. For all, it's the confidence that comes from meeting and exceeding ISO 9001 Quality Assurance Certification. Wide Range of Specialist Services Available Buildings are rarely the same as each other so we specialise in bespoke solutions with air volumes ranging
from 0.1 up to 40.0m3/s. As building regulations change, architects and specifiers continually face new challenges to not only meet revised health and safety requirements but to maintain outstanding aesthetic design. Consequently our help and input can be invaluable. Bespoke manufacture means that a wide range of materials are considered, from simple pentapost constructionunit 7 hvac with knock-in corners and galvanised infill panels, to fully welded stainless steel units for more hostile applications.determining ac tonnage from unit The versatility of our air handling units enables all methods of heating, cooling and heat recovery to be incorporated,in wall ac and heating unit with humidification and dehumidification also available.
Our bespoke solutions also include fully packaged units incorporating dx heat pumps or cooling with factory wired automatic control systems which have the benefit of being both cost effective and time saving on site. Company Philosophy of Continual Investment We're not only committed to a superior quality of product but also to provide the high quality service that customers now expect. With over 30 years experience we have learnt to listen to your needs and answer them first time. This, coupled with our bespoke, yet practical design approach, enables even the most stringent design specification requirements to be fulfilled. All enquiries relating to design, installation and aftercare are dealt with quickly and effectively, providing advice and assistance second to none. Our flexible manufacturing systems enable us to provide realistic production and delivery schedules suited to fast track projects. We're ready to help you with a unique and complete ventilation solution for any project.
To experience our service either email us at technicalsupport@mansfieldpollard.co.uk or phone us on 01274 774050. Preliminary design, at tender stage, is undertaken by our technical sales staff and is based upon the required volumes, taking into account any limiting factors or unit specification. Once an order is placed, the project is passed to our contracts department, where the initial design will be fine-tuned and finalised by our highly experienced contracts engineers. General arrangement drawings are then produced, using up to date CAD facilities, and are issued for written approval prior to manufacture Although materials may vary with the unit size and application, all AHUs are of a similar construction; namely an outer framework of posts, assembled using knock in corners, into which double skin, insulated enclosure panels are fitted to form a rigid, airtight compartment. Smaller units can be supplied as a single section, whereas larger units are usually supplied in modular form, split into manageable sections for final assembly (bolting-up) on site.
AHU sections are generally supplied with a sturdy channel base support frame, complete with lifting holes to facilitate craneage. All internal components, such as the fan and motor assembly, are built in to the unit sections and are provided with access or removable panels, if necessary, to facilitate maintenance and removal. All forms of component commonly utilised in air handling equipment can be incorporated into the design such as filters, heaters, coolers, humidifiers, attenuators, plate heat exchangers, thermal wheels and run around coil heat recovery systems.

Imofa UK’s overall unit designs and component selection focus on achieving maximum energy efficiency within any building restrictions on unit size and configuration, and cost limitations. The latest developments in high efficiency heat recovery are employed to minimise energy costs, satisfy energy efficiency regulations part L, and contribute to building owners objectves on carbon emissions. Vertical or horizontal, double deck or side-by side design configurations are employed to suit building space restrictions and operating criteria, and are supplied as a single unit, modules, or flat-pack for site assembly. Units for standard ventilation applications are aluminium penta-post construction with double skin 25mm or 50mm, panels with galvanised mild steel inner skin and plastisol coated mild steel outer skin. The panels enclose high density rockwool material with good acoustic and thermal insulation properties. Higher specifications include units to comply with HTM03 -01 for hospital operating theatres, and individual companies’ specific requirements for cleanrooms, swimming pools, and process systems in the food and pharmaceutical manufacturing industry .
