Oppfinnelsen angår et blokkvarmekraftverk bestående av en varmekraftmaskin hvis avvanne er ført via varmevekslere for varmeforsyning, samt en strømgenerator tilkoblet denne. The invention relates to a block thermal power plant consisting of a thermal power machine whose waste water is led via heat exchangers for heat supply, as well as a power generator connected to this.
Slike blokkvarmekraftverk er kjent. I tidsrom med lite varmebehov er de imidlertid dårlig utnyttet. Such block heating power plants are known. However, during periods of low heat demand, they are poorly utilized.
Til grunn for oppfinnelsen ligger den oppgave å utnytte primærenergi optimalt for varmeforsyning av varmeforbrukere og også å ta kraftverket til hjelp for å dekke belastningstopper. The invention is based on the task of optimally utilizing primary energy for heat supply of heat consumers and also of using the power plant to help cover load peaks.
Ifølge oppfinnelsen blir denne oppgave løst ved at strøm-generatoren, som er utført som asynkronmaskin med to akselender, er innrettet til efter valg å kobles til varmekraftmaskinen og/ eller til kompressoren hos en varmepumpe hvis kondensator ligger i serie med varmekraftmaskinens varmevekslere. Dermed fås mulig-het for i tidsrom med stort varmebehov å drive varmekraftmaskinen via den tomt medløpende asynkronmaskin i fellesskap med varmepumpen eller i tidsrom med lite varmebehov å stanse varme-kraf tmaskinen og drive varmepumpen ved hjelp av asynkronmaskinen med denne tilkoblet nettet som motor eller bare koble asynkronmaskinen som generator til varmekraftmaskinen for å dekke last-topper eller å levere nødstrøm. According to the invention, this task is solved by the fact that the power generator, which is designed as an asynchronous machine with two shaft ends, is designed to be optionally connected to the heat engine and/or to the compressor of a heat pump whose condenser is in series with the heat engine's heat exchangers. This makes it possible to operate the heat generator via the idle running asynchronous machine together with the heat pump in periods of high heat demand, or in periods of low heat demand to stop the heat generator and operate the heat pump using the asynchronous machine with this connected network as a motor or only connect the asynchronous machine as a generator to the thermal power machine to cover load peaks or to supply emergency power.
Oppfinnelsen vil bli belyst nærmere i det følgende ved et utførelseseksempel som er vist skjematisk på tegningen. The invention will be explained in more detail in the following by means of an embodiment which is shown schematically in the drawing.
For tilgodegjørelse av avvarmen er der til en varmekraftmaskin 1, f.eks. en forbrenningskraftmaskin eller gassturbin, koblet varmevekslere 2,. 3,. hvis sekundære kretsløp det varme-bærende medium for den eksterne varmeforsyning strømmer gjennom. Ved hjelp av en løsbar kobling 4 er en asynkronmaskin 5 som strøm-generator forbundet med varmekraftmaskinen. Med en ytterligere løsbar kobling 6 er en varmepumpes kompressor 7 koblet til asynkronmaskinen. Varmepumpens kondensator 8 ligger i serie med varmevekslerne 2, 3 i det eksterne varmekretsløp. To compensate for the waste heat, there is a heat power machine 1, e.g. an internal combustion engine or gas turbine, connected heat exchangers 2,. 3,. whose secondary circuits the heat-carrying medium for the external heat supply flows through. By means of a detachable coupling 4, an asynchronous machine 5 as current generator is connected to the thermal power machine. With a further detachable coupling 6, a heat pump's compressor 7 is connected to the asynchronous machine. The heat pump's condenser 8 is in series with the heat exchangers 2, 3 in the external heating circuit.
Med fordel kan man i tillegg tilføre varmepumpens fordamper 9 den varme som et kjølekretsløp opptar fra et rom som skal kjøles. I dette kjølekretsløp transporteres for eksempel vann fra en brønn 10. Brønnvannet transporteres til et basseng 11 og blir ved hjelp av matepumper 12 ledet gjennom forbruks-apparater 13 i rommet som skal kjøles/ og inn .i et tilbakekjølings- basseng 14 samt efter åpning av et ventilsett 15 for en dels vedkommende ført tilbake til bassenget 11 via fordamperen 9. Fra tilbakekjølingsbassenget 14 strømmer vannet tilbake i marken. Advantageously, the heat that a cooling circuit takes up from a room to be cooled can also be added to the heat pump's evaporator 9. In this cooling circuit, for example, water is transported from a well 10. The well water is transported to a pool 11 and is led by means of feed pumps 12 through consumer devices 13 in the room to be cooled/and into a cooling pool 14 and after opening of a valve set 15 is partly led back to the pool 11 via the evaporator 9. From the recooling pool 14, the water flows back into the field.
Med dette anlegg er det mulig å gjennomføre følgende drifts-former: 1. Til tider med øket varmebehov, f.eks. om vinteren og i over-gangstiden, blir den asynkrone maskin 5 sammenkoblet både med varmekraftmaskinen 1 og med varmepumpens kompressor 7. Asynkronmaskinen er skilt fra nettet og løper således med i tom-gang som rotasjonslegeme. Asynkronmaskinens friksjons- og virvelstrømtap utgjør i den forbindelse ca. 2% av akselef-fekten. Ventilsettet 15 i det ekstra kjølekretsløp er åpnet, sa en del av den varme som kjølekretsløpet opptar fra rommet som skal kjøles, via fordamperen blir overført til varmepumpe-kretsløpet. Det ustrømmende vann fra fordamperen mates tilbake til bassenget 11. 2. Til tider med lite varmebehov, f.eks. under utnyttelse av nattstrømtariff om natten, er asynkronmaskinen bare sammenkoblet med varmepumpens kompressor og driver denne som motor. Fordamperen får da likeledes tilført den varme som opptas av kjølekretsløpet. 3. For dekning av belastningstopper er bare asynkronmaskinen koblet til kraftmaskinen og mater som generator inn på nettet. Da varmepumpen er koblet fra, blir ventilsettet 15 i kjøle-kretsløpet lukket. 4. For nødstrømforsyning er asynkronmaskinen likeledes bare koblet til kraftmaskinen og arbeider som generator i paral-lelldrift til en nødstrøm-synkrongenerator. With this system, it is possible to carry out the following modes of operation: 1. At times of increased heat demand, e.g. in the winter and during the transitional period, the asynchronous machine 5 is connected both with the heat power machine 1 and with the heat pump's compressor 7. The asynchronous machine is separated from the grid and thus runs along at idle as a rotating body. In this connection, the asynchronous machine's friction and eddy current losses amount to approx. 2% of the axle effect. The valve set 15 in the additional cooling circuit is opened, so part of the heat that the cooling circuit absorbs from the room to be cooled is transferred via the evaporator to the heat pump circuit. The non-flowing water from the evaporator is fed back to the pool 11. 2. At times of low heat demand, e.g. during night electricity tariff utilization at night, the asynchronous machine is only connected to the heat pump's compressor and drives it as a motor. The evaporator is then also supplied with the heat absorbed by the cooling circuit. 3. To cover load peaks, only the asynchronous machine is connected to the power machine and feeds into the grid as a generator. When the heat pump is disconnected, the valve set 15 in the cooling circuit is closed. 4. For emergency power supply, the asynchronous machine is likewise only connected to the power machine and works as a generator in parallel operation to an emergency power synchronous generator.
