Description

Foreliggende oppfinnelse angår et strålings- og konveksjonselement for himlingsmontasje og omfattende to i avstand fra hverandre anordnede varmevekslere som hver står i varmeledende kontakt med vertikale sidevegger på et oventil og nedentil åpent elementhus, beregnet for å gjennomstrømmes av en luftstrøm. The present invention relates to a radiation and convection element for ceiling mounting and comprising two heat exchangers arranged at a distance from each other, each of which is in heat-conducting contact with vertical side walls of an upper-vent and lower-open element housing, intended to be flowed through by an air current.

Det er kjent å varme opp lokaler med himlingspaneler som er oppvarmet med varmtvann. Likeledes er det kjent å kjøle lokaler ved hjelp av slike kalde paneler som tar opp varme fra omgivelsen. Normalt er kjølemediet kaldt vann med en temperatur på ca. 12-16°C. På grunn av faren for konden-sering av fuktighet i romluften er yttertemperaturen på rør og paneler begrenset til størrelsesorden 12-16°C. Selv om romtemperaturen tillates å bli så høy som 26°C, blir temperaturdifferansen mellom rom/panel bare 10-15°C og varmeopptagingen blir relativt lav. Varmeopptagingen begrenser seg til i størrelsesorden 80 W pr. m^ panel. På grunn av denne relativt lave varmeopptaglng blir prisen på himlingspanel relativt høyt pr. Watt kjøleeffekt. Ofte må panelene dimensjoneres etter maksimal kjølebelastning. It is known to heat premises with ceiling panels that are heated with hot water. Likewise, it is known to cool premises using such cold panels that absorb heat from the surroundings. Normally, the coolant is cold water with a temperature of approx. 12-16°C. Due to the danger of condensation of moisture in the room air, the outside temperature of pipes and panels is limited to the order of 12-16°C. Even if the room temperature is allowed to be as high as 26°C, the temperature difference between room/panel will only be 10-15°C and the heat absorption will be relatively low. Heat absorption is limited to around 80 W per m^ panel. Due to this relatively low heat absorption, the price of ceiling panels is relatively high per Watt cooling effect. The panels often have to be dimensioned according to the maximum cooling load.

Hensikten med oppfinnelsen er å fremskaffe en anordning av den innledningsvis nevnte art ved hjelp av hvilken det er mulig å kombinere varmeopptaglng respektiv avgivelse ved stråling med direkte kjøling respektiv oppvarming ved konveksjon i ett og samme element. Anordningen skal være plassbesparende samt enkel og billig å fremstille. The purpose of the invention is to provide a device of the type mentioned at the outset, by means of which it is possible to combine heat absorption or release by radiation with direct cooling or heating by convection in one and the same element. The device must be space-saving as well as simple and cheap to manufacture.

Dette er ifølge oppfinnelsen oppnådd ved at varmevekslerne oppviser et flensrør, at elementhusets sidevegger holdes sammen ved hjelp av klips eller lignende, og at elementhusene er utformet med en løstagbar nedre endevegg, anordnet i en viss avstand fra den nedre kanten av elementhusets sidevegger, som danner langs vesentlig hele elementhuset for-løpende slisser for den i varmeveksleren kjølte luftstrømmen, og at det mellom varmevekslerne er anordnet en ventilasjonskanal, gjennom hvilken lokalet kan forsynes med tilluft via slissene. According to the invention, this is achieved by the heat exchangers having a flange tube, the side walls of the element housing being held together by means of clips or the like, and the element housings being designed with a removable lower end wall, arranged at a certain distance from the lower edge of the element housing's side walls, which forms slots for the air flow cooled in the heat exchanger along essentially the entire element housing, and that a ventilation channel is arranged between the heat exchangers, through which the room can be supplied with supply air via the slots.

Oppfinnelsen skal i det følgende beskrives nærmere under hen-visning til tegningen som viser et vertikalsnitt gjennom en utførelsesform for et strålings- og konveksjonselement ifølge oppfinnelsen. In the following, the invention will be described in more detail with reference to the drawing which shows a vertical section through an embodiment of a radiation and convection element according to the invention.

Strålings- og konveksjonselementet ifølge oppfinnelsen er sammensatt av lettmetallprofiler som danner et oventil og nedentil åpent elementhus 1, hvis sidevegger 2 og 3 holdes sammen ved hjelp av øvre og nedre klips 4 og 5. En varme-veksler i form av et flensrørsbatteri 6 med et kjølemedium er anordnet i varmeledende kontakt med sideveggene 2 og 3, som av klipsene 4 og 5 holdes spent mot flensrørsbatteriet 6. The radiation and convection element according to the invention is composed of light metal profiles which form an upper and lower open element housing 1, the side walls 2 and 3 of which are held together by means of upper and lower clips 4 and 5. A heat exchanger in the form of a flanged tube battery 6 with a coolant is arranged in heat-conducting contact with the side walls 2 and 3, which are held in tension against the flanged tube battery 6 by the clips 4 and 5.

Elementhuset 1 oppviser videre en nedre endevegg 7 som ved hjelp av snepplåser 8 er festet til de nedre klipsene 5 på utstikkende flenser 9 på disse, i avstand fra sideveggenes 2 og 3 nedre endekanter. Luft fra lokalet kan derved passere gjennom elementhuset 1 over hele dettes lengde og kjøles av flensrørsbatteriet 6, hvoretter den nedkjølte luften passerer ut gjennom de slissene 10 som foreligger mellom sideveggenes 2 og 3 nedre kanter og endeveggen 7. Elementet fungerer således som en ren strålings- og konveksjonsenhet. Endeveggen 7 er trauformet og i denne kan det være anordnet en væskeabsorberende matte 11 for absorpsjon av eventuell kondens. The element housing 1 further has a lower end wall 7 which is attached by means of snap fasteners 8 to the lower clips 5 on protruding flanges 9 on these, at a distance from the lower end edges of the side walls 2 and 3. Air from the room can thereby pass through the element housing 1 over its entire length and is cooled by the flanged pipe battery 6, after which the cooled air passes out through the slits 10 that exist between the lower edges of the side walls 2 and 3 and the end wall 7. The element thus functions as a pure radiation and convection unit. The end wall 7 is trough-shaped and in this a liquid-absorbing mat 11 can be arranged for the absorption of any condensation.

Opphengningsanordninger i form av pendler for elementhuset 1 er tilkoplingsbare til tilkoplingsflenser 24 og klips 4 ved sideveggenes 2 og 3 øvre endekanter. Suspension devices in the form of pendulums for the element housing 1 can be connected to connection flanges 24 and clips 4 at the upper end edges of the side walls 2 and 3.

To elementhus 1 er anordnet i avstand fra hverandre og forbundet via en himlingspanel 12 ved hjelp av klips 13 samt en øvre dekkplate 14. Rommet mellom himlingspanelet 12 og dekkplaten 14 danner en ventilasjonskanal 15 som ved hjelp av en ikke vist vifte forsyner lokalet med tilluft. Denne passerer ut i lokalet gjennom slissene 10 i elementhusene, hvorved den ved hjelp av induksjon trekker med seg sekundær-luft gjennom elementhusene 1. Two element houses 1 are arranged at a distance from each other and connected via a ceiling panel 12 by means of clips 13 and an upper cover plate 14. The space between the ceiling panel 12 and the cover plate 14 forms a ventilation channel 15 which, by means of a fan not shown, supplies the room with supply air. This passes out into the room through the slots 10 in the element housings, whereby it draws secondary air with it through the element housings 1 by means of induction.

En rørsløyfe 16 for et varmemedium er anordnet i varmeledende kontakt med himlingspanelet 12, slik at anordningen kan fungere avvekslende for oppvarming og kjøling av lokalet alt etter behov. Ved dagtid foreligger normalt i for eksempel kontor-, butikk- eller industrilokaler bortsett fra på kalde vinterdager, et varmeoverskudd og om natten et varmeunder-skudd. Rørsløyfene 6 og 16 kan med fordel inngå i et varme-veksler system slik at det i løpet av dagen opptatte varmeoverskudd benyttes for oppvarming av lokalet om natten. A pipe loop 16 for a heating medium is arranged in heat-conducting contact with the ceiling panel 12, so that the device can function alternately for heating and cooling the room as needed. During the day there is normally, for example, office, shop or industrial premises, except on cold winter days, a heat surplus and at night a heat deficit. The pipe loops 6 and 16 can advantageously be included in a heat exchanger system so that the excess heat taken up during the day is used for heating the premises at night.

Oppfinnelsen er ikke begrenset til det viste utførelses-eksempelet, idet flere varianter er tenkelige innen rammen for patentkravene. The invention is not limited to the embodiment shown, since several variants are conceivable within the scope of the patent claims.
