Description
Fremgangsmåte for innstilling av forholdet mellom kompensasjonsluftstrømmen og utblåsingsluftstrømmen i et varmluftsystem. Procedure for setting the ratio between the compensation air flow and the exhaust air flow in a hot air system.
Foreliggende oppfinnelse omhandler en fremgangsmåte ifølge kravenes innledning. The present invention relates to a method according to the preamble of the claims.
Ved varmluftsystemer søker man å oppnå det forhold at det i en bygning strømmer inn like mye kompensasjonsluft som det strømmer utblåsningsluft ut av bygningen. Man har forsøkt å nå dette mål ved å måle den gjennom varmeopptaksanordningen strømmende utgangsluftstrøm og kompensjonssluft-strøm, og etter behov å opprette en nødvendig balanse ved hjelp av reguleringsspjeld. Siden målingen må utføres ved hjelp av pitotrør, er denne fremgangsmåte meget besværlig, bl.a. fordi måleapparatene ikke alltid fungerer. With warm air systems, the aim is to achieve the condition that as much compensation air flows into a building as exhaust air flows out of the building. Attempts have been made to achieve this goal by measuring the output airflow and compensation airflow flowing through the heat absorption device, and if necessary to create a necessary balance by means of a control damper. Since the measurement must be carried out using a pitot tube, this method is very difficult, i.a. because the measuring devices do not always work.
Hensikten med den foreliggende oppfinnelse er å eliminere ulempene ved de kjente fremgangsmåter, og å frem-bringe en helt ny fremgangsmåte for innstilling av forholdet mellom kompensasjonsluftstrømmen og utblåsingsluftstrømmen. The purpose of the present invention is to eliminate the disadvantages of the known methods, and to produce a completely new method for setting the ratio between the compensation air flow and the exhaust air flow.
Oppfinnelsen er basert på den idé at når temperaturforandringen hos begge luftstrømmer etter strømning gjennom varmeopptaksanordningen er like stor, er også luftstrømmene like store. Således får man et meget pålitelig bilde av luftstrømmenes forhold til hverandre ved å måle relevante temperaturforskjeller og sammenligne disse. Riktignok oppnås ikke å fastsette luftstrømmenes absolutte nivå, noe som heller ikke er påkrevet i foreliggende situasjon. The invention is based on the idea that when the temperature change in both air streams after flowing through the heat absorption device is the same, the air flows are also the same. Thus, you get a very reliable picture of the air currents' relationship to each other by measuring relevant temperature differences and comparing these. Admittedly, it is not possible to determine the absolute level of the air flows, which is also not required in the present situation.
Nærmere bestemt kjennetegnes fremgangsmåten ifølge foreliggende oppfinnelse ved det som er angitt i kravenes karak-teriserende deler. More specifically, the method according to the present invention is characterized by what is indicated in the characterizing parts of the claims.
Gjennom oppfinnelsen oppnås betydelige fordeler. Således tilveiebringes de ønskede relative verdier auto-matisk, eksempelvis ved anvendelse av en dator. Når oppfinnelsen benyttes, er det ikke påkrevd å måle luftstrøm-mene. Dessuten blir hele måleprosessen og også innstillings-arbeidet enklere. Significant advantages are achieved through the invention. Thus, the desired relative values are provided automatically, for example by using a computer. When the invention is used, it is not required to measure the air flows. In addition, the entire measurement process and also the setting work become easier.
Fremgangsmåten ifølge oppfinnelsen beskrives i det følgende ved et utførelseseksempel vist på tegningen som skjematisk viser en innretning som anvendes for benyttelse The method according to the invention is described in the following by an embodiment shown in the drawing which schematically shows a device that is used for use
av fremgangsmåten ifølge oppfinnelsen. of the method according to the invention.
Gjennom varmeopptaksanordningen 1 strømmer på den ene side en kompensasjonsluftstrøm V 1 ved påvirkning av en vifte 2 drevet av motoren 3. På tilsvarende måte strømmer en utblåsningsluftstrøm gjennom varmeopptaksanordningen 1 ved påvirkning av en vifte 4 drevet av motoren 5. Ifølge oppfinnelsen måles nå utgangstemperaturen T2 og inngangstemperaturen T. for den kompensasjonsluft V. som går gjennom varmeopptaksanordningen 1. Deretter utregnes disse temperaturers differanse T2 - . På samme måte måles inngangstemperaturen T3 og utgangstemperaturen for den utblåsningsluft som går gjennom vannopptaksanordningen 1, hvoretter disse temperaturers differanse T, - T. beregnes. Siden beregnes forholdet mellom differansene T2 - og Through the heat absorption device 1, on the one hand, a compensatory airflow V 1 flows under the influence of a fan 2 driven by the motor 3. In a similar way, an exhaust air flow flows through the heat absorption device 1 under the influence of a fan 4 driven by the motor 5. According to the invention, the output temperature T2 is now measured and the inlet temperature T. for the compensation air V. which passes through the heat absorption device 1. The difference of these temperatures T2 - is then calculated. In the same way, the inlet temperature T3 and the outlet temperature of the exhaust air passing through the water absorption device 1 are measured, after which the difference of these temperatures T, - T. is calculated. The ratio between the differences T2 - and is then calculated
T3 - T4, dvs. (<T>1<-> T2)/(T3 - <T>4) som samtidig representerer forholdet mellom kompensasjonsluftstrømmen og utblås-ningsluf tstrømmen V2 eller en funksjon derav. T3 - T4, i.e. (<T>1<-> T2)/(T3 - <T>4) which simultaneously represents the ratio between the compensation air flow and the exhaust air flow V2 or a function thereof.
Således er Thus is
TemperaturmålingsresultateneT1 ...T4 mates inn i en dator The temperature measurement results T1 ...T4 are fed into a computer
7, som beregner det ovenfor nevnte forhold, på hvilket grunnlag innstillingen kan utføres manuelt eller av datoren 7. 7, which calculates the above-mentioned ratio, on the basis of which the setting can be carried out manually or by the computer 7.
I eksemplet utføres innstillingen via en koblings-motstand 6 koblet til hver viftes 2, 4 motor 3, 5. In the example, the setting is carried out via a switching resistor 6 connected to each fan's 2, 4 motor 3, 5.
