1 DX SYSTEM HEAT RECOVERY ENHANCED BY DEMAND CONTROLLED VENTILATION

2 2 AERECO DX system DX SYSTEM A COMPLETELY NEW HEAT RECOVERY VENTILATION RANGE With the experience of a very innovative room-by-room demand controlled heat recovery ventilation (HRV) system, several new products now complete the Aereco HRV range. These products are dedicated to residential applications and can be either installed in false ceiling, thanks to a small thickness, or in kitchen cupboard, due to optimized dimensions.

3 AERECO DX System 3 BRING SERENITY AND COMFORT IN YOUR HOME WITH THE NEW DX SYSTEM The DX System is a range of smart heat recovery ventilation systems that continually supply pollen-free and dust-free preheated fresh air to living areas, ensuring a comfortable feel-good climate. Using the DynamiX Technology* which consists of a smart airflow control management, the DX System offers optimal indoor air quality and limits all inherent noises from the ventilation system. This technology allows to the DX System to go beyond standard energy recovery, by adapting with accuracy the airflows to the occupants needs in all rooms. Best energy efficiency Whether fully room-by-room demand controlled (Excellence version) or partially room-by-room controlled at the supply and room-by-room controlled at the exhaust (Premium version), the DX System optimally uses the exhaust heat to preheat the fresh air and thus offers an energy-efficient solution, whatever the version. Moreover, the demand controlled management enables to significantly the electrical consumption of the system. The best energy-efficiency class A+ is achieved by all the versions of the DX System. Comfort and Indoor Air Quality at their best The DX System enhances indoor comfort by providing healthy air, at a milder temperature, preheated by the integrated heat exchanger. To feel good at home, the DynamiX Technology, available on Excellence version, adapts, at any time, both supply and exhaust airflows to the occupants needs in every room through accurate sensors (CO 2 or presence). The DynamiX Technology is a smart demand control strategy specific to the DX System which follows two main purposes: to reduce inherent noise from the heat recovery system while guaranteeing the best Indoor Air Quality. Besides, in order to maximise the filters life-time, their dimensions and filtration surface have been totally optimised to prevent from outdoor particles. Touch screen controls for display, setup and diagnosis A colour LCD touch screen allows the occupant to view system parameters, to diagnose operation, to control setups such as automatic bypass temperature, to boost ventilation or to action a free cooling on demand. It also notifies the occupant when the filters need to be replaced. *specific to Excellence version

4 4 AERECO DX system DYNAMIX TECHNOLOGY : AN OUTSTANDING ENERGY PERFORMANCE THROUGHOUT THE YEAR By combining the benefits of full demand controlled airflows and heat recovery, which are the pillars of the DynamiX technology, the DX System, in Excellence version, delivers outstanding energy performance. Modulation enables a significant reduction in average airflows while providing excellent air quality, with heat losses produced by ventilation lowered by half on average in comparison with a constant airflow ventilation. The heat exchanger operates with a yield of about 87% recovery (DXR efficiency: 82%; DXA efficiency: 93%). Combined, these features achieve about 92% energy savings when compared with a mechanical exhaust ventilation system at constant airflow, with the same indoor air quality. MODULATION 50% savings on the airflows HEAT EXCHANGER 87% + = heat recovery more than 92% savings on air renewal heating 50% savings on electrical consumption The average airflow reduction, due to the demand control ventilation offered by the DX System, also generates important savings on electrical consumption and the impact of this on preheating and fan power (see below) is very positive, saving more than 50% electrical power in comparaison with a constant airflow heat recovery with 92% efficiency. Heat recovery 92% efficiency 50% savings on the electrical consumption Pre-heating (electrical) Fans consumption (electrical) Heat losses through ventilation Aereco DX System heat recovery Average power consumption Conventional heat recovery How a full demand controlled airflows can reduce electrical consumption of the fans In addition to significant energy savings on heat losses, the DX System reduces primary energy consumption by reducing fan power of the unit. The fan type used (highly efficient brushless electronic commutation motors), low pressure operation and average airflow reduction through demand controlled ventilation (50%) allow the DX System to work at an average power greatly reduced compared to that of a standard heat recovery system using one or several speeds. Power consumption is thereby reduced by more than 50%. DX SYSTEM Average airflow Filters kept clean longer = less power consumption By reducing the average airflows (by about 50%) with an equivalent indoor air quality, the DX System reduces the rate of filters clogging, thanks to the reduce volume of air passing through the filters at any given period. Filter durability is doubled compared to traditional heat recovery systems, thereby reducing pressure drops and the power consumption of the motors.

5 AERECO DX System 5 DX SYSTEM - AS FLEXIBLE AS NEEDED, FOR RENOVATION AND NEW BUILD Through the DX System, a completely new range of heat recovery ventilation systems has been designed by Aereco to offer you the maximal flexibility in your choice for the adequate ventilation solution. False ceiling installation Designed for ceiling installation within the heated space, the DXR provides a truly elegant solution for multi-apartments buildings, where available space for systems is often limited, particularly in renovation projects. Its very low thickness (26 cm) and its reduced width (65 cm) allow easy installation in ceiling spaces (for example in a corridor false ceiling). The DXR unit is compatible with two demand control strategies used in the DX System Premium and Excellence. Wall mounted application The DXA has been specifically designed for cupboards installation. Thanks to its well-fitted dimensions, the DXA can be installed both in kitchen and in other technical rooms, wall-mounted. A creamy white metal sheet covers the front face of the the DXA which allows it to be unnoticed as a technical equipment. The DXA unit is compatible with two demand control strategies used in the DX System Premium and Excellence. SIMPLIFIED INSTALLATION AND EASY FILTERS CHANGE DXR and DXA have been specifically designed to ensure that only one person is required to install them. Wether it is done by using an ingenious concept for the DXR or by specific handles on the side fore the DXA, both of these new products use innovative concept to simplified their installation. Filters can be easily replaced without dismounting the unit, both on the DXR and on the DXA, by just simply removing the trapdoors.

6 6 AERECO DX system A SMART SYSTEM AVAILABLE IN TWO VERSIONS OPTIMISED FOR THE AIRFLOW CONTROL The DX System is comprised of a heat recovery unit (DXA Unit or DXR Unit 1 ) connected to exhaust and supply ductworks. The counter-flow heat exchanger, integrated into the main unit, ensures the recovery and transfer of most of the energy from the exhaust air to the supply air, thus limiting the energy required to heat the fresh air. Airflows are automatically controlled according to the needs of each dwelling s room (room by room DCV): Outdoor filtered air is supplied 3 in the bedrooms and in the living room. Stale air is extracted 6 from the kitchen, bathroom and WC. On the supply side, depending on the DX System version installed, one or many sensors 5 can adjust the airflow to all main rooms based on the CO 2 level or based on the presence detection. On the exhaust side, the BXC units adjust automatically the airflow, according to parameters read by various sensors: humidity (used in the kitchen, in the bathroom and in WC), presence (can be used in WC). Versions with switch, presence, remote, CO 2 or VOC sensors can also be used for exhaust units. At all times, total supply airflows and total exhaust airflows are measured by the heat recovery unit. These airflows are balanced thanks to an exhaust controlled compensation valve 8. This valve can be located in the bathroom or in the kitchen. In Excellence version only, an additional compensation valve, integrated in the DX Hub 2, adjusts supply compensation airflow, supplying preheated 9 fresh air in the living room, in the kitchen or in a corridor. Compensation valves are linked to dedicated compensation exhaust unit 7 or dedicated compensation supply unit 4. The use of an exhaust compensation valve is also a solution to increase considerably the airflows. This scenario is used in order to get a very efficient over-ventilation mode, also called free cooling mode. To reach the required supply airflows in each main room (bedrooms or living room), dedicated dampers located in the DX Hub 2 modulate room by room supply airflows according to the information sent by each electronic sensors placed in the main rooms. For example, when the main rooms are occupied, the presence or CO 2 sensors that are located in these rooms send the information to the system to adapt the airflow according to the demand. To reach the required exhaust airflows in each technical room (kitchen, bathroom, WC,...), dampers located in the exhaust units modulate room by room extract airflows according to the passive or active sensor placed within each exhaust unit. Supply airflows and exhaust airflows are measured by the use of accurate pressure sensors placed in the heat recovery unit. This allows to calculate with a high accuracy supply and exhaust airflows, without influence of clogging filters or ductwork pressure drop. It ensures the highest efficiency for the system. So that, energy savings are at their maximum.

7 AERECO DX System 7 Excellence version The Excellence version corresponds to the best HRV solution in terms of indoor air quality and energy savings. In this version, the DX System uses the DynamiX Technology, which consists in adapting airflows room-by-room based on specific needs, while balancing supply and exhaust. An active distribution box, DX Hub, connected to CO 2 or presence sensors located in all the main rooms, adjusts supply airflows through driven dampers. The exhaust airflows are controlled by humidity sensors or presence detectors or other activators included in the exhaust units. Premium version The Premium version keeps the very precise demand control management of the Excellence version, but the supply airflows are controlled globally through at least one CO 2 or presence sensor located in a main room (no active DX Hub is used). Exhaust and supply airflows are permanently balanced. Exhaust airflows are controlled by humidity sensors or presence detectors (notably) built in the exhaust units. The DynamiX Technology, ensures a total quietness of the system and optimal indoor air quality, providing a maximum comfort at home.
