To make sure we feel comfort\u00adable in our own four walls, it\u2019s impor\u00adtant to have not just an appro\u00adpriate setting, but above all a pleasant room climate. However, vapors from objects, as well as biochem\u00adical processes such as breathing or sweating, reduce the air quality in homes. The humidity also rises when cooking, show\u00adering or doing laundry \u2013 if there is no adequate venti\u00adlation, mold can grow. This damages rooms and their inhab\u00adi\u00adtants.<\/p>\n

These prob\u00adlems can be prevented with effi\u00adcient room venti\u00adlation. But many homes are empty a lot of the time, as the resi\u00addents are at work or engaged in other activ\u00adi\u00adties out of the house. However, most venti\u00adlation systems work at constant air flow \u2013 even in situ\u00ada\u00adtions where this is not neces\u00adsary at all. So they consume energy unnec\u00ades\u00adsarily. In the event of high activity in the rooms, on the other hand, air exchange is often not suffi\u00adcient to improve the air quality. This is why French manu\u00adfac\u00adturer AERECO has devel\u00adoped demand-based venti\u00adlation. The system adapts its perfor\u00admance to the use of space and only works when it is really needed.<\/p>\n

Fresh air flows into the building through air outlets at the windows (1). In exhaust air rooms, a demand-driven humidity-controlled exhaust air element (2) guides the air into the exhaust air shaft. Hybrid fans on the roof (3) adjust their speed depending on the outside temper\u00ada\u00adtures. (Illus\u00adtra\u00adtion | AERECO)<\/p><\/div><\/div>\n

Sensors control inlet and exhaust air flaps<\/h2>\n

It works as follows: AERECO sensors measure air quality in the home using several para\u00adme\u00adters. If the quality drops, the system opens the flaps installed in outside air ducts in the living and sleeping areas, thereby auto\u00admat\u00adi\u00adcally replacing the required air volume. For example, if the humidity in the home rises, the flaps open more and more fresh outside air is let in. Connected exhaust air elements also work this way in kitchens, bath\u00adrooms and WCs: They extract the air more quickly. <\/p>\n

Support for free venti\u00adlation<\/h2>\n

AERECO relies on hybrid venti\u00adlation, i.e. the combi\u00adna\u00adtion of free and fan-supported venti\u00adlation. A low-pres\u00adsure fan designed for this purpose gener\u00adates a constant under\u00adpres\u00adsure in the shaft. If the thermal lift is not suffi\u00adcient, the fan switches on auto\u00admat\u00adi\u00adcally, thus supporting the venti\u00adlation system. Various hybrid venti\u00adlation systems mounted on the building roof ensure that this is done quickly and effi\u00adciently: The VBP product family with low air perfor\u00admance levels of up to 400 m3<\/sup>\/h, the VBP+ devices for high air perfor\u00admance of up to 800 m3<\/sup>\/h and the fire-proof fans of the VBP+<\/sup>C4 series.<\/p>\n

The indi\u00advidual rotor blades of the VBP low-pres\u00adsure venti\u00adlation unit run parallel to the air flow. This means that the entire free cross-section of the shaft is avail\u00adable, which ensures shaft venti\u00adlation even without mechan\u00adical support. To drive the fan, AERECO uses an ebm-papst EC motor with sepa\u00adrate commu\u00adta\u00adtion elec\u00adtronics. Reli\u00ada\u00adbility was crucial when selecting the compo\u00adnents. The motor\u2019s dura\u00adbility was partic\u00adu\u00adlarly impor\u00adtant to the company. ebm-papst\u2019s prod\u00aducts also have a good repu\u00adta\u00adtion among end customers. The motor circuit board is in a plastic box and the cable\u2019s struc\u00adture is simple. The elec\u00adtronics box in a sepa\u00adrate loca\u00adtion can be mounted outside the air flow. The connec\u00adtion box can thus be installed in an easily acces\u00adsible posi\u00adtion on the venti\u00adlation unit.<\/p>\n

Depending on the outside temper\u00ada\u00adture, a power supply and control unit controls up to 25 venti\u00adlation units and switches them from the basic speed that prevents freezing in winter to the required speed. A VBP venti\u00adlation unit can venti\u00adlate multi-family homes with up to seven stories and can also be mounted on existing shafts.<\/p>\n

Maximum power, minimum consump\u00adtion<\/h2>\n

The VBP+ hybrid venti\u00adlation unit provides an advan\u00adtage in terms of energy effi\u00adciency. It oper\u00adates at 35 W with an air perfor\u00admance of 800 m3<\/sup>\/h, reducing energy consump\u00adtion to a minimum. An ebm-papst EC motor also contributes to this. For AERECO, it was very impor\u00adtant to have an effi\u00adcient drive that helps signif\u00adi\u00adcantly reduce energy consump\u00adtion while also oper\u00adating reli\u00adably.<\/p>\n

With a housing made of galva\u00adnized steel and a matrix of calcium sili\u00adcate that protects the motor, the venti\u00adlation unit can with\u00adstand temper\u00ada\u00adtures of up to 400 degrees Celsius for up to 30 minutes.<\/p>\n<\/blockquote>\n

The venti\u00adlation system auto\u00admat\u00adi\u00adcally adapts to the weather condi\u00adtions, ensuring a constant under\u00adpres\u00adsure at all times. The VBP+<\/sup> C4 is also suit\u00adable for smoke in the event of a fire. With a housing made of galva\u00adnized steel and a matrix of calcium sili\u00adcate that protects the motor, the venti\u00adlation unit can with\u00adstand temper\u00ada\u00adtures of up to 400 degrees Celsius for up to 30 minutes.<\/p>\n

In use when\u00adever neces\u00adsary<\/h2>\n

Thanks to the pres\u00adence detec\u00adtion and CO2<\/sub> or VOC sensors in resi\u00adden\u00adtial areas, the fans are only switched on when air actu\u00adally needs to be extracted. If the house is empty, the venti\u00adlation system auto\u00admat\u00adi\u00adcally reduces the air exchange; the fresh air supply and exhaust air flow are then reduced. This saves heating energy, reduces the current consump\u00adtion of the venti\u00adlation units \u2013 and ensures good air throughout the house at all times.<\/p>\n","protected":false},"excerpt":{"rendered":"
