8 pplications Schools In buildings for school, the load to be disposed is variable during the day due to the presence of people only for some periods, thus it is mandatory to control the users requirements during daily plant use. Systemair offers a wide range of equipment suitable for this purpose, the fan coils with EC motors allow to obtain the required flexibility. Offices In buildings for tertiary application, the air conditioning and the ventilation are necessary during the day. The heat loads to be removed are generally generated by people present, from the lighting system, from solar radiation and by machines. Normally it is necessary the use of chillers, Heat Pump to produce cold and/or hot water to be sent to hydronic (fan coils, cassettes, ducted) to obtain an optimum air conditioning of offices.

9 Commercial buildings Normally the number of people varies continuously; the optimal solution would be to use machinery for the conditioning with variable flow and with constant monitoring of concentration of pollutants (VOC and CO 2 ). Systemair products can easily meet the plantʼs requirement. Industry Industrial plants generate a large amount of heat that must be dissipated in the appropriate way. Systemair offers a wide range of products (chillers from 20 kw to kw) that can be readily integrated industrial installation. The chiller can be used both for air conditioning and for the cooling equipment process (production of chilled water up to -10 C). Hotels In the hotel rooms, it is needed a high level of comfort with the minimum impact with respect to the noise level. Systemair ducted products equipped with EC motors fully comply with requirements efficiency, cooling capacity and sound impact, required by this type of installations.

12 12 Split and Multi systems Ecodesign regulation ErP Directive 2009/125 The new regulation have been adopted by the European Parliament to achieve the goals to reduce the power consumption in Europe related to air conditioning business and other home appliance as well as air-to-water heat pump, air handling, ventilation etc. With its strategic plan called 20/20/20, Europe aims to reduce the CO 2 emissions by 20%, using 20% more renewable energy and consuming 20% less primary energy by In order to facilitate the achievement of these objectives, EU issued the ErP Directive that specifies the eco-design requirements for placing on the market the energy-using products. For split air conditioners with power less than 12 kw, the minimum requirements are based on a new index of seasonal efficiency and on the sound power level as shown in the table below: /C <6 kw /C 6-12 kw SEER SCOP SEER SCOP SEER/SCOP min. 4,6 3,8 4,3 3,8 L w indoor max. 60 db() 65 db() L w outdoor max. 65 db() 70 db() 20% less emissions of CO 2 gas 20% more use of renewable energy 20% less use of primary energy Measuring the performance in real conditions The European Union requires the application of objective metrics for measuring performance in order to establish the minimum requirements and provide customers with information regarding the performance of air conditioning useful for their purchase. The methodology used up to 2012 and based on the efficiency rating (EER) presents a significant difference between the predicted and actual performance. For this reason a more accurate method has beed designed: the seasonal efficiency ratio (SEER). mong the most significant changes it includes the introduction of different operating temperatures for cooling and heating, the possibility of use of energy both at partial load and full load and power usage in standby and off mode. Considering that most systems operate mostly in partload conditions, the new methodology will allow to assess better the performance of a unit in real conditions.

13 Split and Multi systems 13 New energy classification New energy classification in force from 1 January 2013 The transition to the concept of seasonal efficiency involves the development of a completely new energy label which shows the energy class based on the values of SEER and SCOP and the main characteristics of the product such as the sound power level of the indoor and outdoor units. Energy efficiency in heating is presented with three different values according to the climate where the product is installed. For the manufacturer of the product is mandatory to indicate the values for the Temperate climate ( verge heating value), those of the other two climates are optional. The data and energy efficiency classes are declared in accordance with EN The energy class shown in the new label, both in cooling and in heating, can not be compared to the energy class that had the old energy label as the latter was based on specific indices (EER and COP) and not on seasonal indices SEER and SCOP. The energy efficiency classes for split air conditioners are shown in the table below: Energy Efficiency Class SEER SCOP +++ SEER 8,50 SCOP 5, ,10 SEER < 8,50 4,60 SCOP < 5,10 + 5,60 SEER < 6,10 4,00 SCOP < 4,60 5,10 SEER < 5,60 3,40 SCOP < 4,00 B 4,60 SEER < 5,10 3,10 SCOP < 3,40 C 4,10 SEER < 4,60 2,80 SCOP < 3,10 D 3,60 SEER < 4,10 2,50 SCOP < 2,80 E 3,10 SEER < 3,60 2,20 SCOP < 2,50 F 2,60 SEER < 3,10 1,90 SCOP < 2,20 G SEER < 2,60 SCOP < 1,90

In response to market demands Systemair offers several types and sizes of indoor units: wallmounted, cassette, floor-ceiling and duct. Outdoor units Mini, despite the compact dimensions, solve different tasks of air conditioning on small objects. Six modular outdoor units can be combined in one refrigerant system thus reaching a total cooling capacity of up to 200 kw. Separately, to highlight the 3 Pipe heat recovery system for indipendent and simultaneous cooling and heating operation. The most comfortable temperature n important advantage of the multi-zone air-conditioning is a smooth and rapid achievement of a comfortable temperature, as well as maintaining the specified parameters accurate to ± 0,5 C. Such high performance was achieved thanks to an accurate control of the refrigerant flow and the mechanism of redistribution of refrigerant between the several units, implemented with the help of electronic expansion valves. High energy efficiency The efficiency of multi-zone systems is very high, because each time the electric power is consumed as much as necessary to carry out user requirements. If the indoor units work only in a few areas of the building, then the power consumption is reduced proportionally by changing the refrigerant flow. Continuous development in the field of management In modern air-conditioning systems the demand for automation and control systems integrated with other infrastructure building systems is continuously increasing. These are exactly the principles on the basic of the development of the control systems of Systemair. In addition to the traditional control systems of air conditioning, the user deals with different possibilities of control that can solve the various needs of the building management such as the possibility of control via personal computer and Internet network connection. Simplicity of design Systemair provides full integration and coordination of all elements of a multizone system, greatly simplifies the task of the designer. The selection process can be performed in maximum short period of time by using a simple and complete selection and designing software. Low noise Low noise of both outdoor and indoor units makes the job a multizone system virtually inconspicuous.
