1 GOLD AIR HANDLING SYSTEM OVERVIEW

2 Four unbeatable reasons why you should choose GOLD units. GOLD PX Plate heat exchanger GOLD RX Rotary heat exchanger GOLD CX Coil heat exchanger GOLD SD Supply air and extract air handling units Saves space The GOLD has compact dimensions and furthermore it is possible to connect sharp duct bends directly to the air handling unit without pressure losses. This saves you space in the plant room. Optimal operating economy Energy-saving fans, efficient heat recovery and full control of temperatures, airflows and operating times offer optimal operational economy. Economical control functions A large number of functions integrated into the control system are ready to be activated via a hand-held micro terminal. Several of the functions provide unique opportunities for saving energy. Plug and Play Ready-to-use control functions are provided for accessories such as cooling units and heating coils and wiring is done by means of cables with quick connector. Plug and Play! New Products, 2007 In 2005, we introduced plate-type and coil-type heat exchangers for the GOLD units. During 2006, we presented the GOLD SD supply air and extract air handling units. Here are the new products for 2007: ReCO 2 Energy-saving function and accessories for recirculating extract air with guaranteed air quality. The function is patentpending. See page 20. Xzone Function and accessories for controlling two temperature zones. Preheating Function and accessories for preheating outdoor air. Prefilter Function and accessories for prefiltering outdoor air and/or extract air. The new ReCO 2 function can be used for saving energy in an air handling unit equipped with the air recirculation section accessory. 2 Registered design.

3 Energy efficiency brought into focus. Optimized heat recovery and cooling energy recovery Swegon s rotary heat exchangers (RX) offer unbeatable temperature efficiency, up to 85% and low pressure drop. The rotary heat exchanger recovers cooling energy just as efficiently, especially if you select one with hygroscopically coated rotor surfaces. However, in some applications, the airflow paths through the heat exchanger must be completely separate from one another. Such applications call for the use of a plate heat exchanger (GOLD PX) or coil heat exchangers (GOLD CX and GOLD SD). These alternative heat exchangers have an energy-efficient, anti-frost protection system that also measures humidity in the extract air. This ensures that the efficiency will not be controlled to the min. setpoint until the actual risk of freezing is imminent. Swegon s heat exchangers cut your costs of operating the heating and cooling system of the building to optimally low levels. Energy-efficient fans The motor and frequency inverter of the fans in the GOLD units are optimized to generate the best output while consuming as little power as possible. The motors perform to Class EFF1, i.e. their performance measures up to the highest efficiency rating classified by the EU and CEMEP European Committee of Manufacturers of Electrical Machines and Power Electronics. The frequency inverters also have a high power factor. This enables the electrical installation of fuses with lower rating. The fans are compact and take up little space. Sharp bends can be connected directly against the fan outlet without pressure losses. Low noise level enables the use of smaller sound absorbers in some applications the ventilation system can be selected completely without them. Swegon s fans offer low energy consumption, low installation costs, low pressure losses and space saved. Registered design.

4 Tools worth their weight in gold. An intelligent economist Pressures, airflows, temperatures, energy recovery and operating periods can be controlled in the IQnomic control system, which is standard in all the GOLD air handling units. Practically all the functions you can think of for an air handling unit are incorporated into the system and they are all ready to be activated. There are also several unique energy-saving functions such as Cooling Boost, density-corrected airflow and season-related airflow. All the settings and readings can be entered/viewed in plain text via a user-friendly, hand-held micro terminal. As standard, the GOLD has support for all the usual communication standards (TCP/IP, EIA 485 and EIA 232). The TBLZ communication unit can also be used for communication via LON and Trend. The GOLD also has a built-in web communication function ready to be connected to the network. All you need is an ordinary computer connected to the network. The fact that the control equipment is integrated into and specifically developed for the GOLD ensures that its electronics and mechanics operate hand in hand. This also offers you the chance to come a step further than you would with a control system built up of standard components. The IQnomic involves substantially lower costs compared with the planning, procuring, programming, configuring and installation of conventional control components and supervisory systems. ProUnit makes it easy to choose the right unit ProUnit helps you select the right air handling unit. You can access this fully web-based software from Swegon s website. In ProUnit, you can procure project-specific flow diagrams, compare heat exchanger options, estimate energy costs, life cycle costs, procure a contractor demarcation list and see how you will be benefited by using specific control functions. By linking to AutoCAD and MagiCAD, models can be exported for use in the design work. ProUnit makes it an easy task to select the right GOLD unit for an optimal and energy-efficient indoor climate. 4 Registered design.

5 Effective solutions with the GOLD. Decentralized ventilation Swegon has a history of creating pioneering products and the GOLD is generally used as a criterion by both clients and competitors. Swegon has also taken a step further and developed solutions aimed at giving the client maximal return on investment. Decentralised ventilation is one example. The concept involves using several smaller air handling units, instead of one single large unit. Each unit serves its own smaller section of the building and this offers the client increased profitability. A decentralized solution namely sets more floor surface free that can generate additional income from leases. This is possible in that the GOLD unit takes up little space and the level of sound it generates is low. The operating costs are in many cases also lower because the fans, heat recovery and controls in smaller air handling units are more efficient than those of a larger unit. One single large ventilation unit in the cellar, for instance, requires considerable floor surface and large shafts (upper illustration). With the GOLD system, it is possible to have one air handling unit on each floor of the building occupying the same space as the shaft. This leaves the whole cellar free for lettable floor surface for car parking spaces, for instance (lower illustration). Further benefits are that the building becomes more flexible, because it is easier to adapt the ventilation system to each tenant s specific comfort requirements and that the building can be completed by stages both in new-building and refurbishment schemes. Decentralized ventilation using GOLD units sets floor surface free for other uses and offers enhanced flexibility.

6 Here s how you in particular earn by the GOLD. The Architect The GOLD requires limited space for installation without having to compromise performance and quality. Thanks to its low noise level and attractive design, the GOLD can even be installed somewhere right inside the premises being air conditioned. Accessories well-suited to their purpose also make it possible to install GOLD units outdoors. Your work is made substantially easier by GOLD flexibility and your creativity is never restricted, rather the reverse! The Consultant The GOLD units are easy to place because they can be connected to ducting in a number of ways. No extensive work is required for describing how the control, regulating and supervisory system should be designed; all this is there, integrated into the GOLD. A description and flow charts can be obtained from the ProUnit air handling unit selection software. Correct technical data and knowledge that the units have been granted certification by Eurovent are additional guarantees that no unpleasant surprises will arise when the ventilation system is put into operation. You don t have to reinvent the wheel; you can instead focus on making good use of GOLD functionality and energy efficiency in the best possible way. The Installer The GOLD can be installed quickly and easily. In applications that require external functions such as dampers, presence detectors or a cooling unit, these can be easily wired to clearly marked terminal blocks. Certain wiring operations are done directly with modular connectors. Should the passageways through the site prove to be narrow; the larger air handling units can be easily split into sections. The GOLD is the ideal alternative for turnkey contract projects. All the necessary functions are built in; you need only activate those required, including communication and supervision. You are spared unpleasant surprises and you never need to face the risk that your tender won t make both ends meet! The Client/User The GOLD units offer hard-to-beat operating economy and life cycle costs (LCC) in a class of their own. Their flexibility is unparalleled and is of great benefit when ventilation prerequisites change, for rebuilding projects, etc. The GOLD can exchange information with most communication systems available on the market. In buildings that have a data network of their own, the GOLD can be connected to the network just as easily as it is to connect a printer, for instance. You will never notice that the air handling unit is working backstage. You ll be reminded of its presence only by its low operating and life cycle costs and that everyone who spends time or rents rooms in the building are satisfied, contented and willing to pay! 6 Registered design.

7 Technical description General General The GOLD RX/PX/CX one-piece units are complete air handling units with direct-driven supply air and extract air fans, supply air and extract air filters and heat exchanger. The heat exchanger is either of rotary type (RX), plate type (PX) or consists of two coils (CX). The GOLD SD single-direction units are supply air/extract air handling units with one direct-driven supply air or extract air fan. Optional filters are available for all sizes. Heat exchanger coils and unmounted pipework package can be selected for the size units. The GOLD has built-in control equipment that can be operated from the hand-held micro terminal with clear-text display. The electrical and control system is completely integrated into the air handling unit. The microprocessor-based equipment controls and regulates temperatures, airflows and other functions. A large number of functions are built into the system and are simple to activate. If supplementary function sections such as dampers and air coolers are required, they must be installed in the ductwork. With provision for cooling and heating The GOLD is also well suited for cooling, preheating and postheating. The control functions in the control system are ready to activate and the relevant items of equipment are available as accessories. Range of application The GOLD units are designed for use in comfort ventilation applications. Depending on the variant selected, GOLD units can be utilised in buildings such as office buildings, schools, day nurseries, public buildings, shops, residential buildings, etc. GOLD units equipped with plate/coil heat exchanger (PX/CX) and separate supply air and extract air handling units (SD) can also be used for the ventilation of moderately humid buildings; however not where the humidity is continuously high, such as in indoor swimming baths. The separate GOLD supply air and extract air handling units (SD) are designed for applications in which the supply air and extract air flows need to be completely separated from one another or where, due to limited available space, separate units for supply air and extract air are needed. They can also be used individually if only one of the variants is needed. GOLD units can be installed outdoors and then must be equipped with with roof, air intake section and exhaust air hood accessories. Certification Swegon AB has a certificated Quality Management System that conforms to ISO 9001 and an Environmental Management System that conforms to ISO Standards. The GOLD Air Handling System is also certificated by Eurovent, No. AHU GOLD RX GOLD PX GOLD CX GOLD SD Certificate No Registered design.
