Description
BA S K E T O F R E G E N E RAT I V E H EAT E X C HA N G E R
Field of the Invention
This invention relates to a structure of baskets for regenerative heat exchangers, which can use as basic parts of equipments for local forced energy-saving ventilation of separate rooms of dwelling houses, public buildings, and factories.
Background Art
Free ventilation of said rooms through ventlights or transoms results in losses of heat used for heating in winter and increase of energy consumption for air-cooling by conditioners in su mmer. It is clear for each person skilled in the art that energy losses owing to free ventilation will be the greater, the greater are cubic content of a ventilated room, temperature difference between atmosphere and this room, and predetermined rate of air circulation.
Above-mentioned energy losses can decrease using equipment for local forced energy-saving ventilation that warms or cools fresh air, which is sucking from atmosphere into a closed room, by heat interchange with spent air, which is throwing out from this room into atmosphere.
Two basic kinds of heat exchangers have known at present, notably:
Recuperators, in which heat-exchange between flows of fresh and spent actuating media (specifically, air) having different temperature happens through heat-conducting partitions, which separate respective ducts for passing of such flows, and
Regenerators, in which heat-exchange between flows of fresh and spent actuating media realizes by alternate transmission of theirs through ducts within a flow-trough heat- capacious filling.
See, for example, Bonbinow OHUMKnoneflMMecKnii cnoBapb ΠΟίΙΙ ITEXHHM ECKI/ll l. - M: HayMHoe n3AaTenbCTBo « EonbLuafl Poccni iCKaa 3Hi MKJioneflM?i » , cnoBapHaa cTaTbn «Tennoo6ivieHHMK» , c.526; In English: Great encyclopaedic dictionary POLYTECHNIC - Moscow: Scientific Publishing House "Great Russian Encyclopaedia", the entry "Heat exchanger", p.526
Well-known advantages of recuperators consist in that they can make in a wide range of dimensions from a few centimeters to tens meters , and, correspondingly, in a widest range of heat flows from a few hundreds watts to megawatts.
These advantages cause such fact that majority of available at the market equipments for local forced energy-saving ventilation have equipped with recuperators
Unfortunately, such recuperative heat exchangers are, as a rule, cumbersome and heavy. This raises appreciably the price of such equipments and complicate assemblage and maintenance service of theirs. E.g. , the equipment according to the UA 1 1 134 U has based on a shell-and-tube recuperative heat exchanger. Their tube plates serve as airtight partitions and divide cavity of a housing of said exchanger into two chambers, which are independently communicating with atmosphere and a ventilated room through tubes and tube space respectively and through respective inlet and outlet adjutages.
SUBSTITUTE SHEET
UA 71959 U discloses more perfect recuperative equipment for local forced energy- saving ventilation . It has such heat exchanger, in which heat-conducting partitions have made as thin plates from aluminic or copper foil.
Naturally, this lamellar recuperative heat exchanger is appreciably less resource- demanding and more compact and useful in operation in comparison with any other shell- and-tube recuperative heat exchanger. However, it is difficult-to-make and inconvenient.
Of late designers and producers of equipments for local forced energy-saving ventilation pay attention to simple regenerative heat exchangers.
They use for a long time in heavy and processing industries for heating of gaseous fuel, air or air-gas mixtures using heat of spent combustion products by means of their alternate transmission through ducts within a flow-trough heat-capacious filling (See, for example, 5onbwoi/i 3Hu,nKnoneflHHecKni/i cnoBapb nOJlMTEXHMMECKI Ιΐ . - M: HayMHoe M3flaTenbCTB0 « SonbwaFi PoccwiicKaa 3HU,HKnoneflna » , cnoBapnaa CTaTba « PereHepaTop B τθπποτεχΗΜΚθ» , c.447; In English: Great encyclopaedic dictionary POLYTECHNIC. - Moscow: Scientific Publishing House "Great Russian Encyclopaedia", the entry "Regenerator in heat technology", p.447).
Industrial regenerative heat exchangers operate usually at temperature differences up to several hundreds Celsius degrees and at flow discharge up to one or more thousand cubic meter per hour. Respectively, they have overall dimensions about a few meters. This allows easy and simply assemblage of heat-capacious filling by use of single pieces such as refractory bricks or temperature-resistant metal plates.
However, regenerative equipments for local forced energy-saving ventilation must be, as a rule, small-size in order do not spoil interior and not impede arrangement of furniture or technical equipment and movement of people within any habitable ventilated room. Especially, said equipments must have appreciably less than 1 m lengthwise and less than 0.5 m in breadth and in height or in diameter.
At present, these conditions have realized using such available equipments for local forced energy-saving ventilation that are equipped with baskets based on heat-capacious material in the form of ceramic monoblocks having parallel flow-trough holes.
The nearest analog of proposed further basket of regenerative heat exchanger having above-mentioned ceramic monoblock disclosed in picture of equipment for local forced energy-saving ventilation «ΤΒΜΗ Φρθίΐι» and « PeBeHTa» (see, respectively, web sites http://vents.ua/cat/61 8/ and http://www.reventa.com.ua).
Each such known basket of regenerative heat exchanger has - A hollow (specifically round in cross-section) housing,
A heat-capacious filling of said housing (specifically in the form of above-mentioned ceramic monoblock having a plurality of round or quadratic in cross-section parallel flow- trough holes measuring from 1 .5 to 3.5 mm, which have divided by walls measuring from 0.5 to 1 .5 mm), and
Manifolds, which are located on ends of said filling and serve by-turn, in operative

position, for inlet and outlet of heated or cooled air flows.
Previously mentioned equipments for local forced energy-saving ventilation have only one such basket, a double-acting fan, an adjustable timer and a changeover valve.
Unfortunately, preparation of ceramic monoblocks is labor-consuming. Moreover, their operating surfaces have appreciable roughness arisen because burning and sintering of rough workpieces. Such roughness is capable to increase air resistance and can retain impurities within said flow-trough holes that promote further degradation of operating characteristics. This forces to use of cleanable or disposable air filters, which increase air resistance additionally. Therefore known equipments for local forced energy-saving ventilation, which have ceramic regenerative heat exchangers, are inconvenient and unreliable and provide small-scale productivity (as a rule no more than 30 m3/h).
Summary of the Invention
The invention has based on the problem to create - by change of material and structure of heat-capacious filling - such manufacturable basket of regenerative heat exchanger, which would have smooth operating surfaces and, appropriately, would be substantially more efficient and reliable in service.
This problem has solved in that a basket of regenerative heat exchanger according to the invention comprises - A hollow housing,
A heat-capacious filling of this housing that has a plurality of parallel flow-trough holes and is made from thermoplastic polymeric material in the form of at least two laminary components, each pair of which is separated by regularly located partitions serving as walls of said flow-trough holes, and
Manifolds that are located on ends of said filling and serve by-turn, in operative position, for inlet and outlet of heated or cooled air flows,
Application of thermoplastic polymeric materials for fabrication of the heat-capacious filling (preferably by extrusion of long-length semimanufactured article and subsequent gage resawing of it) allows forming perfectly smooth walls of said flow-trough holes even if operating surfaces of extrusion heads have a certain roughness. Thus, polymer melt surface tension force smoothes all surfaces of any heat-capacious filling immediately at outlet of it from extrusion zone.
First additional feature consists in that said laminary components shaped as flat plates. This allows to use thin decorative facing polymeric (especially, polyvinylchloride) panels as semimanufactured articles suitable for production of said fillings. Such panels are accessible and affordable and have plurality of flow-trough holes between their walls initially. Therefore, these panels can easy and simple transform into segments, which are capable to assemble heat-capacious fillings having any desired cross-section profile.
Second additional feature consists in that said laminary components are ring-like shaped and concentrically spaced. This is reasonable, if semimanufactured articles of said heat-capacious fillings must make using a flow line method (preferably extrusion).
Brief Description of the Drawings
The invention will now be explained by detailed description of the proposed basket of regenerative heat exchanger with references to the accompanying drawings, in which - Fig.1 shows general view of this basket (longitudinal section);
Figs 2, 3, and 4 show some samples of possible (namely quadratic, rhomboid and triangular) shapes of profiles of flow-trough holes between flat laminary components of the heat-capacious filling of this basket; and
Fig.5 shows one possible cross-section of such single-block heat-capacious filling of this basket that has composed of ring-like concentric laminary components and radially oriented partitions between these components.
Best Embodiments of the Invention
Each proposed basket of regenerative heat exchanger comprises (see Fig.1 ) - A hollow housing 1 , which can be made from metal (and, in this case, equipped with not shown here a heat-insulating coat) or from a heat-insulating polymeric material;
A flow-trough heat-capacious filling 2 fixed rigidly within the housing 1 ; this filling 2 made from thermoplastic polymeric material as at least two laminary components 3, each pair of which separated by shown on Figs 2, 3, 4 and 5 (but designated further) regularly located partitions that serve as smooth walls of not designated many parallel flow-trough holes; and
Manifolds 4 and 5 that are located on ends of said filling 2 and serve by-turn, in operative position, for inlet and outlet of heated or cooled air flows.
The housing 1 can have an arbitrary geometrical form. Especially, it can be a circular or elliptic cylinder, rectangular (usually quadratic), hexagonal or other (not necessary regular) prism (having, in particular, rounded joints of faces) etc.
Said filling 2 cam make from any (preferably pure) thermoplastic that has specific heat capacity and chemical resistance to typical domestic and industrial corrosive agents no less than ceramics, e.g. pure polyvinylchloride, isotactic polypropylene, polycarbonate on the basis of diphenylol propane (Lexan®) etc.
So, ceramics used in known baskets of regenerative heat exchangers has specific heat capacity in the range from 0.83 to 1 .1 kilojoules/kg.K, whereas this thermotechnical parameter of thermoplastics are in the range from 1.05 to 2.14 kilojoules/kg.K
(polyvinylchloride) and up to 2.0 kilojoules/kg-K (polypropylene and polycarbonate).
Moreover, resistance of these thermoplastics to the ethanol or acetone vapor and to the vegetable and fish oils or animal fats is indubitable. Therefore, each person skilled in the art can easily select a thermoplastic that is suitable for fabrication of a specific flow-trough heat-capacious filling 2.
Parts of the hollow housing 1 , which project over ends of said filling 2 as it showed on
Fig.1 , can serve as simplest manifolds 4 and 5. However, each person skilled in the art comprehends that said manifolds 4 and 5 can make in the form of not shown here flare fittings, each of which serves in turn as diffusor of air letting into said filling 2 and as
confuser of air discharged from it, when a regenerative heat exchanger operates.
Laminary components 3 can make as at least two flat plates having partitions 6 (see samples on the Figs 2, 3 and 4). Now polyvinylchloride thin-layer decorative facing panels having a plurality of parallel flow-trough holes are available at the world market. Such panels can easily and simple cut into pieces meant for assemblage of said flow-trough heat- capacious filling 2 with a glance of specific geometrical forms of housings 1 .
Fig.5 shows such possible design of the basket of regenerative heat exchanger, in which laminary components 3 of the said filling 2 have ring-like (in particular, round) form and concentrically spaced, whereas partitions 6 between such components 3 are oriented radially.
The proposed basket can use in twofold number for production of batteries of highly productive regenerative heat exchangers that are equipped with well-known tools for control airflows.
Such batteries can provide cooling of warm air and accumulation of heat in the filling 2 of one basket and, simultaneously, heating of cold air by egress of heat from the filling 2 of second basket of each their pair.
The above-described basket of regenerative heat exchanger operates by alternate transmission of warm or cold air through parallel flow-trough holes in heat-capacious filling 2 (for instance, during 50-90 s in each direction). Respectively, said laminary components 3 and said partitions 6 accumulate heat during contact with warm air and then return essential part of accumulated heat to cold air, and vice versa
Industrial Applicability
Use of thermoplastics as materials for fabrication of heat-capacious fillings of baskets of regenerative heat exchangers allows substantial reducing the price of equipments for local forced energy-saving ventilation and increase of their service reliability.
