2 Recover... your wellbeing The home is a precious asset where we all spend a major time of your life. So it s important that it be kept as clean as possible. Ventilation, whether mechanical or natural, allows us to control factors such as temperature, humidity and pollutants in the air, preventing the formation of surface and interstitial condensation and the subsequent development of unpleasant mould. Given that nowadays buildings are highly insulated against outside temperatures, it is becoming increasingly difficult to eliminate vapours generated in indoor environments on a daily basis. In fact, the mere presence of a person inside a room releases a significant quantity of moisture humidity. Moreover, simple actions such as washing our hands, drying clothes or cooking, release significant quantities of aqueous vapours. Unless the building is properly ventilated, this aqueous vapour will tend to condense on relatively colder surfaces such as the walls; if the building is properly ventilated however, this excess moisture will be pushed towards the outside, thereby preventing the formation of condensation. In addition to maintaining air temperature and relative humidity conditions, ventilation allows control over pollutants inside the home; simply think about the quantity of CO 2 each person releases when breathing, simple actions such as cooking (which releases fumes and odours into the environment), cleaning the home (which releases airborne organic compounds contained in cleaning products) or smoking a cigarette (which releases nicotine and other polluting elements). Moreover, inside the buildings hide a series of other pollutants often unbeknownst to us, such as pollens or insects (which enter the home during the different seasons throughout the year), radon (a natural gas found in soil, which infiltrates homes) or carbon monoxide (due to poor combustion in heating systems or stoves). So it s not only indoor environments that are polluted, but also outdoor ones. s a consequence however, given that rooms are ventilated during the part of the day when environmental pollution is at its highest, ventilation itself can be dangerous for the air we breathe. Until today, the most common method of exchanging air in indoor environments was to open the doors and windows, but given the hectic rhythms of modern day life, this isn t always easy. Moreover, compared to older buildings, modern construction technology has made building insulation even more efficient; however, while allowing us to use less energy for heating, this also results in significantly less air infiltration, particularly from the doors and windows. Unlike natural ventilation systems, a controlled mechanical system always ensures the right quantity of air is exchanged. The process is continuous and adjustable depending on the activities being performed by the occupants. The exchanged air is continuously controlled through a filtration system that prevents the introduction of pollutants from the outside. This is why Emmeti recovers your wellbeing, allowing you to live in a healthy environment thanks to correct air temperature and relative humidity conditions and significantly less pollutants.

3 Recover... your energy The cost of energy and power savings are a continuous source of worry during everyday life. simple gesture such as opening the doors and windows to exchange the air can increase the cost of heating in buildings by more than a third. In order to ensure correct ventilation in the home, as well as healthy conditions in the environments in which we live, doors and windows should be opened for twenty minutes every two hours; in addition to being a complicated operation in light of our daily routines, this is also extremely wasteful from an economical point of view due to the cold air that is subsequently let inside. On the other hand, a controlled mechanical ventilation system with heat recovery ensures the correct level of air exchange, with almost zero impact on heating costs. Thanks to high-efficiency heat recovery, the warm air present in the rooms cross with the cold air from the outside, without ever mixing, transferring the heat. This simple device reduces external energy dispersion throughout the various periods of the year. In fact, while it prevents heat from escaping the building in the winter months, it also prevents the heat from entering in the summer months, thereby significantly reducing building operating costs. Moreover, thanks to mechanical ventilation systems, it is possible to monitor the correct flow of air from the outside, based on the real needs of the building. This means that unlike in the case of natural ventilation by opening windows, occupants can enjoy a healthy environment, exchanging only the air effectively necessary in order to ensure maximum comfort. By recovering the energy already present in the different environments, the building becomes more efficient, less economically wasteful and requires less energy to work. ll this improve the building energy certification, helping to maintain and even improve the building s value over time. The Emmeti offer, also includes the standard version of the Recupera Slim model, which is controlled by external commands and an utomatic version supplied standard with a simple multi-purpose command for complete unit management. Both models can be combined with external sensors (motion, CO 2 and humidity) and are equipped with EC high-efficiency brushless motors, which considerably reduce consumption and allow improved regulation of the air flow based on the real needs of each individual system. This is why Emmeti recovers your energy, allowing you to live in an efficient home, with real energy savings.

6 How Recupera Slim autonomous works The exhaust air from the more polluting rooms like bathrooms, kitchens and laundry rooms is expelled by a mechanical ventilation system, introducing clean air taken from outdoors into noble areas like living rooms or bedrooms, recovering the energy in the exhaust air Fresh air Exaust air The system is made of the following components: 1 Recupera Slim: 2 fans actioned by low consumption brushless motors, force inlet air flow (from internal rooms) and external air throughout a high efficiency-crossed flows heat recovery unit. In this way the internal heat can be recovered. The air is taken from the rooms and from outside by the fans, and passes them through the recovery unit at highly efficient crossed flows, recovering the energy contained inside the house. 2 Multi-function control with LCD display: controls the ventilation flow rate and gives information on any filters cleaning or replacements. 3 External air grills: allow inlet and expulsion of air avoiding entrance to the building of foreign bodies and water. 4 Distribution plenum: it is a piping network within the building that distributes and regulates air inside the building, avoiding transmission of noise inside the house. 5 Terminals: they distribute the air flow inside rooms avoiding creation of annoying drafts and transmission of noise between different rooms.
