Description
Anordning ved sentralvarmeanlegg. Device at central heating systems.
Foreliggende oppfinnelse angår en anordning ved sentralvarmeanlegg hvor radiatorer avhengig av sine reguleringsventiler gjennomstrømmes av varmt vann fra en ledningskurs. The present invention relates to a device in a central heating system where radiators, depending on their control valves, are flowed through by hot water from a line course.
Slike sentralvarmeanlegg har den It has such central heating systems
ulempe at hvis alle radiatorer som er til-knyttet samme kurs er stengt, sirkulerer det ikke noe varmt vann i kursen og når der åpnes for tilstrømning til en radiator, må først en del avkjølt vann, avhengig av høyden av radiatoren i forhold til kjelen, passere radiatoren før det varme vann når frem til samme. I slike anlegg er det også nødvendig med en shuntledning over kjelen mellom utløps- og innløpsledningene for å hindr at kjelen blir kald i bunnen. disadvantage that if all radiators connected to the same course are closed, no hot water circulates in the course and when the flow to a radiator is opened, a portion of cooled water must first, depending on the height of the radiator in relation to the boiler, pass the radiator before the hot water reaches it. In such systems, it is also necessary to have a shunt line above the boiler between the outlet and inlet lines to prevent the boiler from becoming cold at the bottom.
Det er tidligere foreslått et sentralvarmeanlegg som sørger for at det stadig sirkulerer varmt vann i ledningskursene, slik at shuntledningen over kjelen kan sløy-fes, og varmt vann umiddelbart kan tilføres radiatorene ved åpning av deres ventiler. I dette anlegg er hver radiator forsynt med en shuntledning i forbindelse med en reguleringsventil som alltid gir samme gjen-nomstrømning av kursen ved at den del av det varme vann som ikke passerer radiatoren sendes gjennom shuntledningen. A central heating system has previously been proposed which ensures that hot water constantly circulates in the line courses, so that the shunt line above the boiler can be looped, and hot water can be immediately supplied to the radiators by opening their valves. In this system, each radiator is provided with a shunt line in connection with a control valve which always provides the same through-flow of the course by sending the part of the hot water that does not pass the radiator through the shunt line.
Hensikten med oppfinnelse er å tilveie-bringe et sentralvarmeanlegg som har de samme fordeler som det ovenfor nevnte, men som er betydelig enklere og billigere, i og med at shuntledningen på hver radiator kan sløyfes og at en betydelig billigere regulerinsventil kan anvendes. The purpose of the invention is to provide a central heating system which has the same advantages as the one mentioned above, but which is significantly simpler and cheaper, in that the shunt line on each radiator can be looped and that a significantly cheaper regulating valve can be used.
Det oppnåes ifølge oppfinnelsen ved at der i den øvre ende av hver ledningskurs er anordnet en forbindelsesledning mellom til- og returledningen. According to the invention, this is achieved by arranging a connection line between the supply and return line at the upper end of each cable course.
For at mengden av strømningsvann i de forskjellige ledningskurser skal kunne innstilles i forhold til hverandre er der ifølge oppfinnelsen i forbindelsesledningen satt inn en reguleringsventil. In order that the amount of flowing water in the different pipe courses can be set in relation to each other, according to the invention, a control valve is inserted in the connecting pipe.
Et utførelseeksempel på oppfinnelsen skal beskrives nærmere under henvisning til tegningen. An embodiment of the invention shall be described in more detail with reference to the drawing.
På tegningen mater kjelen 1 to kurser med radiatorer 2 som reguleres ved hjelp av termostatstyrte ventiler 3. Den ene kurs består av en tilledning 4 og en returledning In the drawing, the boiler 1 feeds two courses with radiators 2 which are regulated using thermostatically controlled valves 3. One course consists of a supply line 4 and a return line
5 som i den øvre ende er forbundet med 5 which at the upper end is connected to
hverandre ved et ledningsstykke 9, hvori er satt inn en reguleringsventil 10. Den annen kurs består av tilledningen 6 og returledningen 7 og de øvre ender av kursen er forbundet med hverandre ved ledningsstyk-■ket 9 som inneholder en reguleringsventil 10. Sirkulasjonen av det varme vann fra each other by a line piece 9, in which a control valve 10 is inserted. The other course consists of the supply line 6 and the return line 7 and the upper ends of the course are connected to each other by the line piece 9 which contains a control valve 10. The circulation of the hot water from
kjelen i kursene befordres av pumpen 8 som ligger i returledningen. Da de to kurser er ujevnt belastet, kan man ved hjelp av reguleringsventilene 10 innstille en gang for alle det riktige forhold mellom kursenes gjennomstrømning. En fordel ved et anlegg the boiler in the courses is conveyed by the pump 8 located in the return line. As the two courses are unevenly loaded, the correct ratio between the courses' flow can be set once and for all with the help of the control valves 10. An advantage of a facility
som her beskrevet i forhold til det innled-ningsvis nevnte er at man i det første nevnte kan benytte termostatstyrte ventiler til en rimelig pris på radiatorene, mens det annet anlegg vanskelig kan ter-mostatstyres. as described here in relation to the initially mentioned is that in the first mentioned you can use thermostatically controlled valves at a reasonable price on the radiators, while the other system can hardly be thermostatically controlled.
