Description
Anordning for gjenvinning av varme'fraDevice for recovery of heat'from
fra et lokale bortfort fraluft tilfrom a local away fort from air to
innfort tilluft.enter supply air.
Oppfinnelsen angår en anordning for gjenvinning av varme fra fra et lokale bortfort fraluft,'der den gjenvundne varme tilfores til den i lokalet innforte tilluft ved hjelp av et ventilasjonsaggregat som omfatter en kappe som inneholder dels en fraluftkanal og en parallell tilluftkanal, The invention relates to a device for recovering heat from a local exhaust air outlet, where the recovered heat is supplied to the supply air brought into the room by means of a ventilation unit which comprises a casing which partly contains an exhaust air duct and a parallel supply air duct,
og dels ett eller flere varmevekslerbatterier for over-and partly one or more heat exchanger batteries for over-
foring av varme fra fraluften til tilluften.conduction of heat from the exhaust air to the supply air.
Konvensjonelle apparater for ventilasjon av lokaler slik som ovenfor angitt er ofte utfort slik at tilbakeføring av varme fra aggregatets fraluft til den.utenfra innforte tilluft skjer gjennom mellomveggen mellom kanalene.. Disse gis ofte en betydelig lengde og forsynes med spesielt ut-formede inn- og utlop for å eliminere en ikke onsket, slumpartet blanding som forårsakes av fraluftens termiske krefter. Sådanne aggregater blir derfor både plass- og materialkrevende.' Ifolge en forbedret utforelse, som er beskrevet i svensk patent nr. 35<*>+ 713 5 er det anordnet to tilluftkanaler, én på hver side av den sentrale fraluftkanal. En felles vifte, som er anbragt i et viftekammer foran fraluftkanalen inn mot lokalet, er forsynt med et spjeldorgan i de omgivende mellomvegger til tilluftkanalene, hvilket organ utnyttes for å gi tilluft hhv. fraluft en viss stromningshastighet, eller alternativt for å bringe en valgfri del av fraluften til å resirkuleres via viften ved innblanding i tilluften.. Conventional devices for the ventilation of premises as stated above are often designed so that the return of heat from the unit's exhaust air to the supply air brought in from outside takes place through the partition between the channels. These are often given a considerable length and supplied with specially designed inlet and outlet to eliminate an unwanted, sloppy mixture caused by the thermal forces of the exhaust air. Such aggregates therefore require both space and materials.' According to an improved embodiment, which is described in Swedish patent no. 35<*>+ 713 5, two supply air channels are arranged, one on each side of the central exhaust air channel. A common fan, which is placed in a fan chamber in front of the exhaust air duct towards the room, is equipped with a damper device in the surrounding intermediate walls of the supply air ducts, which device is used to provide supply air or exhaust air a certain flow rate, or alternatively to bring an optional part of the exhaust air to be recycled via the fan by mixing in the supply air..
Formålet med. oppfinnelsen er å forbedre varmeokonomien ved ventilasjon av et lokale vesentlig, og å tilveiebringe et mer kompakt aggregat og en fra et fremstillingssynspunkt mer fordelaktig utformning av varmevekslerbatteriene. The purpose of. the invention is to significantly improve the heat economy by ventilating a room, and to provide a more compact unit and a more advantageous design of the heat exchanger batteries from a manufacturing point of view.
Anordningen ifolge oppfinnelsen er kjennetegnet ved at hvert varmevekslerbatteri utgjores av et antall gjennom begge kanaler forlopende, hovedsakelig vertikale, ved siden av hverandre parallelt anbragte sloyfer som er dannet av The device according to the invention is characterized by the fact that each heat exchanger battery is made up of a number of, mainly vertical, side-by-side parallel coils extending through both channels, which are formed by
seriekoblede rette ror som er forbundet med rorboyer,series-connected straight rudders connected by rudder buoys,
der de rette ror fortrinnsvis er forsynt med et antall lameller,.og der hver rorsloyfes ene ende er lukket mens den annen ende er forsynt med en påfyllingsnippel for fylling av hver rorsloyfe med en bestemt mengde kjolemedium, og hvilke rorsloyfer er utfort med en mellomvegg mellom sloyfens nedre og ovre del, og slik beliggende i kappen at disse'mellomvegger utgjor en skillevegg mellom ventilasjonsaggregatets fraluftkanal og tilluftkanal i kappen, idet hver rorsloyfes nedre del er anbragt for å strekke seg gjennom fraluftkanalen, mens rorsloyfens ovre del er utfort for å strekke seg gjennom tilluftkanalen. where the straight rudders are preferably provided with a number of lamellas, and where one end of each rudder slot is closed while the other end is provided with a filling nipple for filling each rudder slot with a specific amount of dressing medium, and which rudder slots are extended with a partition between the lower and upper part of the sloyf, and located in the casing in such a way that these 'intermediate walls' form a partition between the ventilation unit's exhaust air duct and the supply air channel in the casing, as the lower part of each rudder sloyfe is placed to extend through the exhaust air duct, while the upper part of the sloyf is extended to extend through the supply air duct.
En fordelaktig utforelse av anordningen er kjenne--tegnet ved. to parallelle viftekamre som er tilkoblet til fraluft- hhv. tilluftkanalenes munninger i kappen og forsynt med. hver sin vifte for mekanisk tvangsstyring av en konstant luftstrom gjennom hver kanal i kappen. An advantageous embodiment of the device is characterized by two parallel fan chambers which are connected to exhaust air - or the mouths of the supply air ducts in the casing and provided with. each fan for mechanical forced control of a constant air flow through each channel in the jacket.
Oppfinnelsen skal beskrives nærmere i det folgende i forbindelse med. tegningene, der fig. 1 viser et perspek-tivisk bilde, av en rorsloyfe ifolge oppfinnelsen, og fig. 2 viser et tverrsnitt av et ventilasjonsaggregat montert til ytterveggen av et lokale og forsynt med to viftekamre med hver sin vifte. The invention shall be described in more detail in the following in connection with. the drawings, where fig. 1 shows a perspective view of a rudder slot according to the invention, and fig. 2 shows a cross-section of a ventilation unit mounted to the outer wall of a room and provided with two fan chambers, each with its own fan.
På tegningene betegner 3 en kappe for et ventilasjonsaggregat 1 som er vist montert ved en åpning i en yttervegg 2.i et lokale 1'. Kappen inneholder en•fraluft-kanal k - og en tilluftkanal 5 - 5' samt varmevekslerbatterier. De to viste parallelle varmevekslerbatterier 9 inneholder hver fire rorsloyfer (henvisningstallet 6''ikke vist) som strekker seg gjennom fraluft- og tilluftkanalene. Rorsloyfene er her fremstilt av et tilsvarende antall ror 7 som oventil og nedentil er forbundet med rorboyer 8 og ved den ene ende er forsynt med hver sin påfyllingsnippel 10 for et kjolemedium som kan gå over fra væske- til dampfase ved for-dampning og gå tilbake til væskefase ved kondensering, avhengig av den omgivende temperatur. Henvisningstallet 11 betegner den på fig. 1 borterste, lukkede ende av hver rorsloyfe. Hver rorsloyfe er omgitt av en lukket ramme 12 og blir for innmonteringen i kappen 3 som en del av varme-vekslerbatteriet fylt av en bestemt mengde kjolemedium, f.eks. freon. En mellomvegg 13 er anordnet mellom sloyfens nedre del, som er beliggende i f raluf tkanalen<*>+ - V, og sloyfens ovre del, som er beliggende i tilluftkanalen 5-5'. Mellomveggen kan i sin enkleste utforelse utgjores av en lufttett pakning. Hver rorsloyfe er i'den viste utforelse forsynt med et antall horisontale lameller 1<*>+. Konvensjonelle varmevekslérbatterier av den her aktuelle type er vanligvis forsynt med et ovre og et nedre horisontalt samlingsror med forholdsvis stor diameter, av- hvilke samlingsror det ene er forsynt med en påfyllingsanordning for det tilsiktede medium, mens det annet samlingsror gjor tjeneste for fordeling av mediet. Foruten at denne utforelse stiller seg vesentlig dyrere i fremstilling, oker den også vekten av det ferdige- varmevekslerbatte.ri , og dermed fordyres fraktomkostningene for det ferdige aggregat. In the drawings, 3 denotes a cover for a ventilation unit 1 which is shown mounted at an opening in an outer wall 2 in a room 1'. The casing contains an exhaust air duct k - and a supply air duct 5 - 5' as well as heat exchanger batteries. The two parallel heat exchanger batteries 9 shown each contain four rudders (reference number 6'' not shown) which extend through the exhaust air and supply air ducts. The rudders are here made of a corresponding number of rudders 7 which are connected above and below with rudders 8 and at one end are each provided with a filling nipple 10 for a dressing medium which can change from liquid to vapor phase during evaporation and return to liquid phase upon condensation, depending on the ambient temperature. The reference number 11 denotes the one in fig. 1 farthest, closed end of each rudder slot. Each rudder slot is surrounded by a closed frame 12 and is filled with a certain amount of dressing medium, e.g. Freon. An intermediate wall 13 is arranged between the lower part of the sloyf, which is located in the air duct <*>+ - V, and the upper part of the sloyf, which is located in the supply air channel 5-5'. In its simplest form, the intermediate wall can be made of an airtight seal. In the embodiment shown, each rudder slot is provided with a number of horizontal slats 1<*>+. Conventional heat exchanger batteries of the type in question here are usually provided with an upper and a lower horizontal header with a relatively large diameter, one of which headers is equipped with a filling device for the intended medium, while the other header serves for distribution of the medium. In addition to the fact that this design is significantly more expensive to manufacture, it also increases the weight of the finished heat exchanger battery, and thus increases the shipping costs for the finished unit.
På grunn av kjolemediets termiske egenskaper vil .kjolemediet ved varmevekslerbatteriets belastning fordele kjolemediet i nodvendig mengde for hvert ror 7 i sloyfen. Under drift overfarer fraluftens varme på kjent måte kjolemediets væskefase i den nedre del av hver sloyfe til dampfase, hvoretter det i den ovre, av tilluften avkjolte del av hver sloyfe, skjer en kondensering under avgivelse av mediets fordampningsvarme til den i. lokalet innforte tilluft. Due to the thermal properties of the dressing medium, the dressing medium will distribute the dressing medium in the necessary amount for each row 7 in the sloyf when the heat exchanger battery is loaded. During operation, the heat of the exhaust air transfers in a known manner from the liquid phase of the dressing medium in the lower part of each sloyfe to vapor phase, after which in the upper, cooled by the supply air part of each sloyfe, condensation takes place while giving off the medium's heat of evaporation to the supply air introduced in the room.
På fig. 2 betegner 15 og 16 to parallelle viftekamre In fig. 2, 15 and 16 denote two parallel fan chambers
som er beliggende foran kanalenes munninger k<1>hhv. 5'.which are located in front of the mouths of the channels k<1>respectively. 5'.
En skillevegg'mellom viftekamrene er betegnet med 13'. Viftekamrene har gitterforsynte åpninger 15'a hhv. 16a, og inne i kamrene er anordnet vegger 15b hhv. 16b som tangerer viftebladene til respektive vifter 17 og 18. Disse drives av en felles motor 19 med en motoraksel 19a på hvis motsatte ender viftene er montert. Ved hjelp av dette "push-pull"-arrangement sikres, en balansert luftstromning gjennom lokalet med like 'stor mengde tilluft som forbrukt luft eller fraluft. Man kan således på enkel måte opprettholde én konstant og forutbestemt strom, uavhengig av trykkfor-holdenei lokalet, f.eks. ved åpning av dorer eller vinduer. Slik som nevnt ovenfor, innebærer oppfinnelsen at man ved hjelp av selvsirkulasjon utnytter kjolemediet som varme-vekslermedium uten bevegelige deler og uten ventiler. Anordningen er derfor særlig godt egnet for lokaler uten overvåkning, der man nå bedre kan utnytte varmeinnholdet A partition wall' between the fan chambers is denoted by 13'. The fan chambers have grid-equipped openings 15'a or 16a, and inside the chambers are arranged walls 15b or 16b which are tangential to the fan blades of respective fans 17 and 18. These are driven by a common motor 19 with a motor shaft 19a on whose opposite ends the fans are mounted. With the help of this "push-pull" arrangement, a balanced airflow through the room is ensured with an equal amount of supply air as consumed air or exhaust air. One can thus easily maintain one constant and predetermined flow, regardless of the pressure conditions in the room, e.g. when opening doors or windows. As mentioned above, the invention implies that, by means of self-circulation, the dressing medium is utilized as a heat-exchange medium without moving parts and without valves. The device is therefore particularly well suited for premises without monitoring, where the heat content can now be better utilized
i den avgående ventilasjonsluft eller fraluft. Vifte-kamrene 15, 16 kan i forekommende tilfelle loftes av for inspeksjon og eventuelt ettersyn av viftene og de i varmevekslerbatteriene inngående rorsloyfer. in the outgoing ventilation air or extract air. The fan chambers 15, 16 can, if necessary, be lifted off for inspection and possibly inspection of the fans and the rudder blades included in the heat exchanger batteries.
