Technical requirements

For the proper operation of ECOPROTEKT units there are some technical demands on the discharged air supplying central vaccuum unit in terms of the steady-state temperature and CVU filtration performance long-term stability. Manufacturers and distributors of central vacuum cleaners are called upon to apply for a certification for their products. Certification will takes place exclusively by our or contractual partners office. The proceeding of certification is free of charge.

Information

The german Energieausweis  is since 01.07.2008 an obligatory certificate, that evaluates, how a building has to be appreciated in matters of energetic. Background of this evaluation is as a general rule the buildings demands on primary energy sources, which is affected by the constructural and the heating systems standard for energy use..

Certifying

The according to requirements engaged filter medias are certificated to F and or G classes and carbon filters for medical appliances and are conform to DIN EN 779. Filter classes F7 - F9 Segregation of respirable dust in air-conditioning technological systems with great demands on air purity, in food branch, minimum requirement as filter class of german hygiene regulations VDI 6022, as a preliminary filter for clean room plants in the pharmaceutical industry, sterilization and operating rooms, switchboard plants and as an intake filter for high-valued assembly rooms.

Central vacuum cleaner and KWL with heat recovery

and with ECOPROTEKT-Home a meaningful combination

Basic view or „which becomes from the energy, which the vacuum cleaner takes up….“?

Acknowledged current position relating on systems of conversion of energy is that at the end of those processes there will be thermal energy remaining. Under a systemic view, in case of a central vacuum cleaner its consumed electric energy (its "total input power") will be converted to caloric energy in different ways. So will the current running trough the motor winding partically be converted directproduce heat by the windings ohmic resistance, also the mechanical work, performed at the moved air by the fan wheel will converted to caloric energy e.g. by its compression ( to be monitored at a bicycle pump ). At least also the generated noise - as a form of kinetic energy - will be converted to caloric energy. The caloric energy will - in case of a central vacuum cleaner - be discharged in different ways, partycally it heats up the central vacuum cleaner itself, which emits this warmth, the major part of warmth will be removed by the dispersing air by blowing outdoors. If the central vacuum cleaner is constructed under the "through-flow" principle the whole caloric energy will be discarded within the single airstream exhausting from the unit, in case of using the "by-pass" principle there will be two streams of air with different volume and enthalpy. The major one - the working air stream carrying the dust and dirt will be blown outdoors, the minor one used too cool down the motor winding is just blown out of the central vacuum cleaners body. As both air streams are propelled by the same motor, the cooling air stream ist to be kept at a minimum to avoid loss of active energy.

Extracted air shroud outwards - economic mischief !

Based on the fundamental consideration in the first section is to notice, that eventually electrical energy is after achieving vacuuming work to be transduced to caloric energy, which is blown out ff the building with the central vacuum cleaners exhaust air. Besides this warm air a central vacuum cleaner also transports compartment air heated up by the space heating out of the building. Consequently the advantage of comfort by using a central vacuum cleaner means a not insignificantly loss of energy.  

Im Falle der Ausstattung des Gebäudes mit einer KWL, evtl. auch mit WRG geht einer oder gehen beide Wärmeteilströme ungenutzt verloren, die Schallbelastung der Umgebung kann beträchtlich sein.    

"attempt at a solution 1" or "what dust problem....?"

A usual way to install acentral vacuum cleaner is - with or without allowance of the wasting of energy specified above - to let the exhaust air blow just in the room the unit is installed in. The problem originated by this layout, common proclaimed in correspondence with a controlled living space ventilation is the exhaust airs affreightment with fine particulate matter. At both different versions of central vacuum cleaner layouts the exhaust air carries particulate matter from two sources. One of the sources is tha vaccum cleaners service air, each central vaccuum cleaner, independently from its inner filter design (e.g. vacuum cleaner bag or cyclonic seperation), has a constructional limited minimum size of particles to be precipitated by the units deposition mechanism.Smaller particles will remain in the air flow. The second source of fine particulate matter is the wear debris to be found in each apparatus, at this juncture mostly particles of the motors carbon brushes, which in case of a bypass design will be carried along by the cooling air. A central vacuum cleaner installed in the described manner will contaminate its room of installation and thereby the complete volume of air in the building by exhausting the air, with all grievous consequences in hygienic and sanitary regards. If the air of the room within the central vacuum cleaner installed is collected by a controlled living space ventilation, will the described enrichment of debris and fine particulate matter sooner or later provoke heightened disposal within the units filter medias or surfaces of the heat exchanger. This yields a degradation of degree of efficiency . Also there is to be considered, that the exhausted air will discharge significant noises within the room the CVC is installed in.  

"attempt at a solution 2"

If it is planned to duct the warmth exhaust air delivered by the central vacuum cleaner directly to a controlled living space ventilation, the following problems will occur: In normal case the controlled living space ventilation will draw warmth compartment air within the range of its governance parameters and will generate the necessary movement of the air by its own blower, whereby the accruing low flow velocity is important for a accurate effectiveness of the heat exchange section and a proper sound deadening. To avoid a fault of the complex electronic control governing the controlled living space ventilation by the CVCs exhaust air stream, here will be operated with technical tricks, e.g. a "party switch" as a workaround makes the electronic control ignore the forced warm air stream trough the heat exchange section. By using tricks like this the controlled living space ventilation is in the forced state of operation without governance at a sacrifice of effectiveness.  

ECOPROTEKT-Home - the expert problem solving

The ECOPROTEKT apparatus can be integrated into planned or already installed central vacuum cleaner installations and permits to prevent the loss of energy shown as above by avoiding uncontrolled substitution of warmth compartment air by cold surrounding air. It also stops the wasting of the caloric energy converted out of the electric input power drawn by the central vacuum cleaner.
