2 ATREA VENTILATION YTEM A T R E A V E N T I L A T I O N Y T E M yem description The ventilation syem provides controlled equal-pressure ventilation with heat recovery for the houses and high-rise residential buildings, together with possible reheating of the supply air, pre-cooling in summer and the effective use of all internal and external energy gains. Properly designed ventilation syem provides fresh filtered air to each room and kitchen and ensures exhau of used air from bathrooms, toilets and kitchens. The company ATREA offers this syem as a complete conruction set, consiing of the following main components: ventilation units with heat recovery series DUPLEX EC5 and ECV5 complete measuring and regulation syem with the option to control other parts of the syem (e.g. a zone butterfly valve, an earth heat exchanger etc.) integrated syem of the ATREA air ducts and fittings suitable for all desired options Using in low-energy and passive houses In the low-energy houses, the ventilation syem supplements a basic heating syem (e.g. central heating units, floor heating etc.). In the passive houses, built in the Czech and lovak Republics, in addition to reheating of the supply air after heat recovery to the building, we also recommend the implementation of the additional heating syem for compliance with the optimum relative humidity in the interior, thus avoiding excessive ventilation during heating. They can also be used in combination with a fireplace insert or other bivalent heat source. With higher demand on cooling or heating by the VAC syem only, it is recommended to choose the ventilation units with air circulation, e.g. the dual-zone units series DUPLEX R5. Ventilation performance Ventilation syem design Based on the long-term measurements and experience with the implementation of the ventilation syems in the residential buildings, the ATREA company recommends dimensioning of the ventilation performance according to CN EN 1551 Class see the marked part of the table below. Legislative requirements The ventilation units DUPLEX EC5 and ECV5 carry energy labels in accordance with EU Regulation no. 15/14 and 154/14.. Ventilation syem advantages Ensure permanent air changes necessary for hygienic reasons with a possibility of one-off increases (e.g. by an external signal from toilets, bathrooms, kitchens or other inputs on the basis of users immediate requirements) avings on ventilation cos by up to 9 % thanks to highly efficient heat recovery exchangers Elimination of mold formation Elimination of thermal discomfort due to air supply with temperature differences kept to a minimum (again as a result of heat recovery with high efficiency) Utilisation of all internal and external thermal gains from the flat space for the heat recovery pre-heating of ventilation air The supply of perfectly filtered air (through Class G4 or F7 filters) significantly reduces the occurrence of allergies and respiratory diseases When the unit is set to full performance (via a by-pass), cooling is possible in summer, particularly through the supply of night filtered air A full-range modular syem allows for easy or even DIY inallation tandard regulation Ventilation intensity in Ventilation Volume per Kitchens Bathrooms Toilets unoccupied rooms intensity person -1-1 (m /h) (m /h) (m /h) (h ) (h ) (m /h) CN EN Z1 Minimum value, , Recommended value, Class, CN EN 1551 nd Class,1,, rd Class, CN 7 54,1,, References to other regulations More documentation for designing a ventilation syem Mounting details Catalogue of components CD election software E A T R E C O V E R Y W A T I I T? Chilled exhau air out + C eated fresh air out + C eat recovery efficiency 9 % Warm exhau air in + C Fresh cool air in C eat recovery principle eat transfer occurs through the separating walls of a heat exchanger in winter warmer exhau air preheats colder supply air. The same principle is applied also in summer for cool recovery. In winter time humidity condensates in exhau air. This condensate increases heat recovery efficiency through improved heat transfer and is continuously drained into a sewer syem. ignificance of heat recovery An energy-optimised heat recovery exchanger reaches a highly economical ratio between power consumption (to run fans), air performance and heat recovery. The fan input vs. heat recovery gain ratio during ventilation reaches an energy efficiency of 4, i.e. from 1 W of power used to run a DUPLEX EC5 up to 4 W is recovered from exhau air. Effective ratio 1 : 4

3 DUPLEX EC5, ECV5 D U P L E X E C 5 / E C V 5 U N I T D E C R I P T I O N Intention The new 5th generation heat recovery units DUPLEX are delivered in two basic lines: DUPLEX EC5 for the inallation under the ceiling and DUPLEX ECV5 in the vertical design. The units are designed for the comfort ventilation of all types of residential and public buildings, are particularly suitable for the low-energy and passive houses and the apartments in the residential buildings with the decentralized ventilation syem. Basic description In the unit housing, made with mineral insulation with the - -1 thickness of mm (U =.81 Wm K ) with the thermal bridges suppression and the reaction to fire class A/A1, a swirling counterflow plaic heat recovery exchanger (efficiency up to 95 %), two ventilators of free impeller type with the electronic EC control and the possibility to supplement regulation for the control of the conant air flow, supply and exhau air filters G4 before entering the recovery heat exchanger, an automatic butterfly valve of the by-pass, a control module and a connection terminal plate are built in. For the ceiling units EC5, condensate outlets in the doors are prepared for both operating positions of the units. Connection nozzles are round, used for connecting flexible or fixed piping with the thermal bridges suppression. Access to the unit is possible through the fully openable hinged door via the locking latches. Units advantages highe energy efficiency class very low height allowing inallation in the ceiling andard built-in fans with free impeller type EC are characterized by very low power consumption and excellent speed regulation higher outputs of the units enable occasional intensive air exhau or summer ventilation recovery efficiency up to 95 % due to the new generation recuperation exchangers excellent thermal insulation parameters of the unit housing with the thermal bridges suppression high sound attenuation of the unit housing due to the high density mineral insulation built-in by-pass is a andard part of the unit and needs no additional space; in addition, due to its conruction, it ensures 1 % by-pass in the by-pass mode without mutual thermal transfer andardly offered two types of regulation meet all the requirements of the unit:.cp easier and cheaper basic digital control syem of the units.rd5 a new digital control syem, optional for inallation, enables connection of a wide range of sensors and other inputs, control of the shut-off and zone butterfly valves of the diribution syem, control of the heaters or the heating syem of the house etc. plus it is andardly equipped with a built-in web server for the possible control via the Internet possibility of inallation of the built-in electrical or external electrical or hot water preheaters/air reheaters possible mirror changes in the EC5 units to the right/left position only by setting the regulation parameter (.RD5 units) or by simple reconnection (.CP units) I N T A L L I N G T E U N I T DUPLEX EC5 under-ceiling type New DUPLEX EC5 units have a very flat design that allows inalling them into even very low suspended ceilings. The minimum requirements for suspended ceiling void heights are in the table. A plaerboard lid is fitted below the unit; in bathrooms the lid mu be airtight and the entire suspended ceiling eam tight. DUPLEX ECV5 vertical type New vertical units DUPLEX 8 ECV5 and 8 ECV5 can be inalled in narrow spaces due to their width, e.g. wardrobes with minimum internal width of 65 mm. min. 5 min. 1 DUPLEX EC5 1 X unit unit height min. height of the ceiling cavity X 17 EC EC EC incl. the door inner min 15 L 1 inlet into sewer min 15 min 15 L 1 inlet into sewer min 15 Condensate drainage During heat recovery heat regaining moiure is condensated during the cooling of exhau air. Water condensates on the walls of the heat recovery exchanger, further increasing heat recovery efficiency. Condensate runs out of the heat recovery exchanger in the direction of air being extracted and is drained from the DUPLEX unit into a sewer syem. For correct functioning and drainage the unit mu be separated from the sewer syem using a siphon of a sufficient height, the recommended minimum being 15 mm. mall condensation drain pumps may be used.
