Description

Anordning ved kjøleanlegg for indirekte kjøling av f. eks. kunstfrosne isbaner. Device at a cooling plant for indirect cooling of e.g. frozen ice rinks.

Foreliggende oppfinnelse vedrører en The present invention relates to a

anordning ved kjøleanlegg for indirekte device at cooling plants for indirect

kjøling av f. eks. kunstfrosne isbaner ved cooling of e.g. artificially frozen ice rinks by

hjelp av en i en lukket krets sirkulerende using one in a closed circuit circulating

kuldebærer. Ved disse anlegg av denne art cold carrier. At these facilities of this nature

må kuldebærerens sirkulasjonsretning periodisk omkastes for at temperaturen langs the cooling medium's circulation direction must be periodically reversed so that the temperature along

kuldebærerrørene skal bli jevnest mulig. the coolant pipes must be as smooth as possible.

Denne omkastning av strømningsretningen This reversal of flow direction

har hittil vanligvis foregått ved hjelp av has so far usually taken place by means of

ventiler som omstilles periodisk. valves that are adjusted periodically.

Av sikkerhetsgrunner har man minst For safety reasons, you have at least

to kuldebærerpumper i hvert anlegg, hvilke two coolant pumps in each plant, which

pumper ennvidere er dimensjonert for hele pumps are furthermore dimensioned for the whole

kuldebærerstrømmen. I henhold til oppfinnelsen anvendes disse pumper på en the coolant flow. According to the invention, these pumps are used on a

sådan måte at man ikke behøver de hittil in such a way that you don't need them until now

anvendte omkasterventiler som er kostbare diverter valves used which are expensive

og forårsaker trykkfall som igjen øker pum-pearbeidet. Oppfinnelsen utmerker seg ved and causes a pressure drop which in turn increases the pumping work. The invention is distinguished by

at kuldebærerens strømningsretning i den that the coolant flow direction in it

lukkede krets er periodisk omkastbar ved closed circuit is periodically reversible by

hjelp av to innbyrdes i motsatt retning periodisk arbeidende pumper som er således with the help of two periodically working pumps in the opposite direction, which are thus

utført at kuldebæreren kan passere gjennom den i øyeblikket stillestående pumpe carried out so that the coolant can pass through the currently stationary pump

med små trykktap. with small pressure losses.

Oppfinnelsen er gjengitt skjematisk på The invention is shown schematically on

tegningen, hvor 1 betegner en kuldebærer-kjøler som avkjøles av et kjølemedium som the drawing, where 1 denotes a coolant cooler which is cooled by a cooling medium which

ledes gjennom en ledning 2 og som f. eks. is led through a line 2 and which, e.g.

fordampes i kjøleren 1. Et ekspansjonskar evaporates in the cooler 1. An expansion vessel

3 tjener til å oppta kuldebærerens volum - 3 serves to occupy the coolant's volume -

variasjoner som følge av temperaturend-ringer. variations due to temperature changes.

Kjøleren 1 er forbundet med et rør- The cooler 1 is connected by a tube

system 4, f. eks. for en isbane over lednin-ger 5 og 6, i hver av hvilke der er innkob-let en pumpe 7 henholdsvis 8 som pumper kuldebæreren i motsatte retninger. system 4, e.g. for an ice track over lines 5 and 6, in each of which a pump 7 and 8 respectively is connected which pumps the coolant in opposite directions.

Pumpene settes igang og stanses av f. eks. et programverk så de bare kan ar-beide vekselvis. For å nedsette påkjennin-gene på pumpemotorene bør der fordelaktig gå så lang tid fra den ene pumpe stan-ser til den annen går igang at kuldebæ-rersirkulasjonen har opphørt eller på det nærmeste opphørt. The pumps are started and stopped by e.g. a piece of software so they can only work alternately. In order to reduce the stress on the pump motors, there should advantageously be such a long period of time between one pump stopping and the other starting that the coolant circulation has ceased or almost ceased.

Behovet for reservepumper er på til-fredsstillende måte tilgodesett ved at man ved feil på en av pumpene uten større u-lemper kan la kuldebæreren strømme bare den ene retning i den tid det tar å få re-parert den feilaktige pumpe. The need for spare pumps is satisfactorily met by the fact that, in the event of a fault on one of the pumps, the coolant can be allowed to flow in only one direction for as long as it takes to repair the faulty pump without major inconvenience.

Da kuldebæreren må passere en stillestående pumpe, er pumpene således dimensjonert at trykkfallet og dermed trykk-tapene i den stillestående pumpe er små. As the coolant must pass a stationary pump, the pumps are dimensioned in such a way that the pressure drop and thus the pressure losses in the stationary pump are small.
