air handling unit sizing

AHU Sizing AHU configurationOur AHU sizing guide enables you to rapidly select the appropriate unit size for a specific project requirement. Simply, select the velocity and volume (or next highest value) required from the table. Then, locate the unit size, external width and external height from the left hand column. Finally, add the base height to the external unit height and 50mm for a pitched roof if the unit will be sited in an external location. Please note that dimensional restrictions may dictate a higher velocity of around 3m³/s. This, however, is likely to mean that the AHU specific fan power will exceed Building Regulations requirements. Subject to external static pressure and internal components, Building Regulations requirements may be met at an AHU velocity of 2m³/s.If the image doesn't display correctly or you wish to download the guide as a PDF please use the link below:AHU sizing guide (matrix below as a .pdf file) Approximate Length of Air Handling Unit Components for Unit Size (.pdf)Approximate Weight of Air Handling Unit Components for Unit Size (.pdf)

Contact our AHU sales engineers for further assistance AHU Unit Design Enquiry Form Contact a Barkell Account Manager Download a product guideOur custom made AHUs cover functions for applications with special demands: energy efficiency, high performance and fast commissioning are some of the qualities applied on packaged and custom AHU ranges. Customer Defined - Customers now have the flexibility to combine modules to build tailor-made AHUs up to 20m³/s. Special Demands - For installations that demand functionality XBOXER an always offer a solution. For instance, the installation might require a humidifier in order to achieve a specific humidity level. The application environment might also require components in aspecific finish, XBOXER can meet this requirement. Flexibility - The possibility to combine single and double deck units has been increased in combinations and sizes within this range. Installations with high demands might need one or a few functions outside the standard range.

The pre-configured and tailored solution ranges can be combined to offer the best solution. The unit platform could be standardised, whereas a selection of the functions are customised making XBOXER the most flexible AHU range available. Project Specific Control - AHUs are sent to site control free allowing them to be integrated with control systems supplied by others. Energy Solutions - Nuaire also offers a number of world class solutions for energy efficiency. The right AHU, designed to meet your budget and site constraints and delivered to deadline. With our infinite range of AHUs you won't need to pay for an oversized unit. The modular design ensures ease of handling at site and online selection ensures that you have just what you need, no more, no less.

air handling units york 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.

An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the offshore unit and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork. Small air handlers, for local use, are called terminal units, and may only include an air filter, coil, and blower; A larger air handler that conditions 100% outside air, and no re-circulated air, is known as a makeup air unit (MAU). Of note is the fact that waste heat powered air handlers are growing in prominence. Some of the factors that contribute to this are the growing focus on solar power as a cost effective renewable energy source which is benefiting demand for solar ventilation units, and the phase-out of fluorocarbon based refrigerants by all governments worldwide to curb the damage caused to the ozone layer.

Some of the minor but notable factors are the implementation of the Kyoto Protocol to tackle climate change, rising energy prices, interest in energy conservation and the robust demand from developing countries. Although there are a lot of growth drivers cost is the primary constraint on the widespread adoption of air handling systems. Moreover, the low thermal efficiency of single-effect handlers has made them non-competitive with readily available free waste heat. Furthermore, air handlers require greater pump energy and larger cooling tower capacity than electric chillers due to the larger volume of water. Opportunity in this industry is widespread due to the availability of low cost units from some manufacturers and the fact that heat from waste can be utilized in an efficient manner. The offshore air handling industry is diversified and can be divided on the basis of energy supply as direct-fired or indirect-fired. They can also be divided based on effect as: (a) Single Effect where the transfer of fluids is through the four major components of the handling machine - evaporator, absorber, generator and condenser;

(b) Double Effect which differs from the single-effect chiller in that there are two condensers and two generators to allow for more refrigerant boil-off from the absorbent solution; and (c) Triple Effect handlers that are under development, as the next step in the evolution of the Heating, Ventilation and Air-Conditioning (HVAC) technology. The Asia-Pacific region is currently the largest and the fastest growing market for air handling units with leading demand coming from developing countries such as India, China and countries in the Malay Archipelago. Soaring temperatures in the U.S. and Mexico are contributing to the demand in the North American region. European countries such as Italy, Spain, U.K., France and Russia have been the leading countries where demand is high. Change in government regulations as well as availability of energy generated from waste are being seen as the demand factors in the Rest of the World, mostly Latin America. The front-runners in the production of offshore air handling systems are: Broad Air Conditioning Co., Ltd., Carrier Corporation, Century Corporation, EAW Energieanlagenbau GmbH, Hitachi Appliances Inc., Johnson Controls, LG Air Conditioning (Shandong) Co., Ltd., Robur Corporation, Thermax Inc., Trane Inc., and Yazaki Energy Systems Inc.
