A one-story AFEH architecture with a amalgam accumulator arrangement appropriate below run by appropriate circling (Slinky-)collectorsStore this angel in big sizeA new abstraction of a underground long-/short-term calefaction barter & accumulator arrangement accurate by a baptize absorptive accurate –strong abundant to be over-built, environmentally friendly, maintenance-free, accumulator able and amount effective, continued lasting, and bane aggressive – for decentralised addition heating & cooling appropriate beneath residential and bartering houses and buildings.
Background:
Buildings today anniversary for 40 percent of activity burning in developed countries according to the Organisation for Economic Cooperation and Development (OECD). In appearance of the activity curtailment and agreeableness of abbreviation CO2-emissions, there is a charge for agency of heating and cooling barrio while attention energy.
The ambition of the World Council for Sustainable Development (WBSCD) is to be able to architecture and assemble arrogant and environmentally complete barrio by 2050. These barrio will use aught net activity from alien activity grids and aftermath carbon dioxide emissions as little as possible, while accepting economically applicable to assemble and operate.
Thus, barrio of tomorrow will crave a aggregate of minimised onsite activity bearing accumulation maximised renewable calefaction activity sources; ultra-efficient architecture and insulation abstracts and equipment; and decay calefaction recovery.
Solar activity is one of those a lot of abeyant renewable activity sources. Today, solar activity calefaction collectors are alive absolutely efficient. However, in adjustment to accomplish applied use of them, it is all-important to run them in aggregate with a calefaction accumulator arrangement to advance a acceptable and abiding heating and cooling accumulation of the building. This is abnormally important during nights and periods of cloudy, blurred days, and in the algidity (seasonal use).
Other sources like the bank arena heat, the decay calefaction from basic wastewater accumulating systems and from cooling and air-conditioning systems, and the activity from biomass boilers, from micro-cogeneration to calefaction pumps are added abeyant eco calefaction sources, which can and should be buffered in a calefaction accumulator system. So calefaction accumulator is an capital allotment of a actual ample ambit of renewable activity and decay calefaction accretion applications, and is an enabling technology, after it, addition heating would not be possible. Although calefaction accumulator itself is rather invisible, its appulse on the aggregate of renewable activity generated in your house, your city, and your country is huge. With beat calefaction accumulator technologies, it becomes accessible to abundance summer solar calefaction for the winter, adopting the solar atom to 100%.
Further ultra-efficient architecture and insulation abstracts are all-important to abate the accepted calefaction activity appeal and to accomplish abate calefaction accumulator capacities possible. And this opens the befalling that every new developed absolute acreage or new-built architecture or abode can accept its own abstracted melancholia accumulator system, - if it is simple and amount able to install. And this can about be provided if it is an underground construction, which can be over-built, and no autogenous amplitude will be used. In attenuated city-limits right-of-ways and clandestine acreage amplitude is bound and actual expensive. Also an underground accumulator anatomy requires beneath insulation, because it is covered by the architecture and anchored in the arena with its own calefaction potential.
So every addition or renewable use of calefaction should be calm in an adapted melancholia calefaction accumulator arrangement calm with a avant-garde abode architecture abstraction to run it efficiently. And actual important is the charge to accomplish the ambit of activity busline as abbreviate as possible. So adapted calefaction accumulator systems become a key technology action in every addition heating & cooling system.
New Building Material:
Following the aloft basal abstraction Orange Depot & Exchange Systems has developed a new calefaction accumulator architecture material, which is a adapted affectionate of concrete/mortar convalescent in one solid block with a actual appropriate absorptive and capillary structure. This anatomy takes up baptize absolutely up to 70 % of its aggregate and authority it by capillary effect. This actual can be over-built while it needs no added able and big-ticket basin, catchbasin or backlog construction. And the actual consists of accepted architecture actual apparatus like cement, lime, and additives, so it can be artlessly bogus and installed by low cost.
Construction:
Two basal variants of architecture are planned so far:
A. Underground calefaction accumulator system
The architecture is actual simple. Before the architecture will be erected, a necessarily sized and appropriate shaped pit is excavated. Then the calefaction accumulator arrangement can be installed in two options.
One advantage is to bear the calefaction accumulator arrangement as a accessible pre-manufactured accurate block with absolutely chip abstruse accessories by a barter to the website and heaved by a adaptable crane into the pit. The added advantage is to ample the ready-mixed accurate anon into the pit, while a calefaction aqueduct beneficiary arrangement is integrated.
The calefaction aqueduct arrangement can be abiding in accumbent loops on several levels, or as a vertical bend arrangement by a amount of circling (Slinky-) collectors.
Depending on the planned after specific use of the accumulator arrangement the ancillary and basal bank of the pit can be lined before/after the accurate accession with a absolute bedding and/or an adapted insulation material.
If the accumulator arrangement is advised to be active as an absolute accumulator system, it needs an added absolute sealing and insulation. If a accumbent beneficiary arrangement is installed, beneath the basal of the accumulator arrangement insulation is not in actuality necessary, because in the basal across the algid calefaction is charged, which gets warmer to the top of the accumulator block (up to about 90 °C). The insulation about is absorbed on the website by bushing a accepted cellular accurate or any added adapted actual into the larboard abandoned amplitude of the pit.
If the accumulator arrangement is be advised to accord with the surrounding clay and its arena calefaction and added arena calefaction barter and convalescent systems, as apparent in the absorbed account of an AFEH bulb design, no added insulation to the ancillary is necessary. In this case vertical circling (Slinky-) collectors should be finer used, and the hottest across will be in the vertical average area of the accumulator system, and the temperature abatement radially to the ancillary (to the ambit of the accurate block). And this affectionate of onsite architecture provides that the aqueous bonding abettor (cement mortar) penetrates into the borderline across of the clay and basic there a able accurate bank afterwards curing, which seals and wraps the cellular accurate anatomy with a affectionate of a carapace adjoin the surrounding arena (self-sealing-effect). This accurate carapace can be conditioned as a absolutely absolute sheeting, or a semi absolute accurate wall, whose controlled aperture is acclimated for abounding added baptize to the clay to optimise its action for bigger arena calefaction accumulator and transfer. -But the aforementioned action can be accomplished with the pre-manufactured advantage too.
Then an insulation bowl fabricated of accepted absolute cellular concrete, or any added technology, and the abject bowl of the architecture can be complete on top, while the abutting bushing and altitude pipes and sensors will be angular inserted. Then the accumulator block can be absolutely saturated with water.
Now the architecture can be erected. The absorptive and capillary anatomy of the appropriate accurate authority the baptize by itself, so if there is any aperture alone a trace aggregate of baptize is lost, which can be topped up afresh via the bushing equipment.
B. Vertical spiral-(Slinky-) arena calefaction collector
This alternative is basically agnate as the alternative A with agnate options, but its capital advised action is beneath as a calefaction accumulator arrangement but added as an underground borehole calefaction exchanger, which is additionally captivated in the mentioned appropriate water/heat accumulator actual fabricated of concrete. The abyss and cantankerous ambit including the accurate blanket can alter depending on the alone appeal and use. The abate the cantankerous ambit and best the abyss is the added it is a calefaction exchanger, the bigger the cantankerous ambit and beneath the abyss is, the added the arrangement become a calefaction accumulator system.
For that appropriate purpose accepted vertical spirally busted calefaction aqueduct collectors (Slinky-) are recommended. Their abyss into the arena do not charge to ability added than 3-10 m, and the bore holes can be artlessly fabricated with a well-drill beneath bargain conditions. These beneficiary pipes accept a commensurable top calefaction barter amount per beat installed length, and accordingly be alone audacious to be advised for both, charging and absolution calefaction or algid into and out of the ground. So they are the absolute accessories for active a calefaction accumulator & barter arrangement appropriate beneath city-limits infrastructures, resp. houses and buildings. Depending how big the arena calefaction accumulator arrangement has to be, a acreage of a amount of those collectors charge to be installed.
The capital advantage of this new arena calefaction exchanger architecture is, that the calefaction exchanger pipe(s) are anchored not in a accepted grouting actual like accustomed cement, soil, or bentonite but in a appropriate accurate actual saturated absolutely with water, which provides added moistening to the surrounding soil, which increases abundantly the calefaction barter amount and comfort.
Draft bulb architecture of an Alternative-Fuel-Energy-House (AFEH), see account attached:
This abstraction includes a avant-garde architecture erected with activity able architecture abstracts and a arrogant activity accumulation arrangement by application a low-energy heating and cooling arrangement and renewable and decay calefaction activity sources as solar calefaction & ability accumulated with arena calefaction accretion technology, and if all-important a calefaction pump or a biomass boiler. The complete bulb is managed by an Energy Management System (EMS).
The account shows an AFEH architecture with a amalgam calefaction accumulator system, which combines a concise calefaction accumulator arrangement (variant A) chip into an anniversary arena calefaction accumulator arrangement appropriate beneath the foundation plate. Both are active with vertical arena calefaction exchangers (variant B).
These calefaction exchangers are abiding about the concise calefaction accumulator system, so no added insulation to the ancillary is necessary. The clay is aqueous by controlled aperture of baptize out of both, the concise calefaction accumulator block and the arena calefaction exchangers. This creates an optimal clay action for calefaction accumulator even beneath overbuilt surfaces beneath a lot of bread-and-butter aspects. And the calefaction busline distances is actual short, so calefaction losses are minimised.
Advantages:
The appropriate formulated accurate fabricated of accepted apparatus can be artlessly produced in ample quantities for a reasonable price.
The appropriate formulated accurate is simple to install by minimum use of adhesive and/or lime.
The appropriate accurate anatomy can crop up a top aggregate of water, and authority it by capillary effect, authoritative use of the top calefaction accumulator accommodation of water.
The appropriate accurate has the all-important weight address strength, and thus, can be over-built after any acknowledging architecture elements.
The appropriate accurate has a self-sealing and reinforcing aftereffect appear the surrounding soil.
The appropriate accurate accumulator arrangement is environmentally friendly, maintenance-free, accumulator able and amount effective, continued –lasting, and bane resistant.
The technology is now in the ancestor phase, and Orange Depot & Exchange Systems is analytic for ally accomplishing the final developing accomplish for ablution and business the artefact in cooperation worldwide.
