Abstract

Det beskrives et C02-varmepumpesystem der reduksjon av ytelseskoeffisienten for varmepumpesyklusen forhindres ved å opprettholde temperaturen i vannet som mates til gasskjøleren i C02-varmepumpen, under en viss temperatur og å heve varmekildesidetemperaturen i fordamperen, og som har funksjoner som tilveiebringer en varmekilde ikke bare for varmtvannsforsyningsutstyr, men også for tilførsel av en varmekilde eller en kuldekilde til luftkondisjoneringsutstyr eller annet. Systemet omfatter en lavtemperaturvanntank (6), en høytemperaturvanntank (9) for lagring av høytemperaturvann som er oppvarmet i en gasskjøler (3), rørledning (10, 12) for tilførsel av høytemperaturvann til varmtvannsforsyningsutstyr, henholdsvis romoppvarmingsutstyr, en første varmeveksler (21) hvori saltlake (vann) for tilførsel av latent fordampingsvarme for C02-kjølemiddel til kjølemidlet i fordamperen (5) bytter varme med varmeavgivende fluid (fluid hvorfra varme trekkes av), en andre varmeveksler lokalisert oppstrøms den første varmeveksler for å avkjøle høytemperaturvannet etter at det er benyttet som varmekilde for romoppvarmingsutstyret (derfor er temperaturen allerede ikke så høy) ved varmeveksling med det varmemotakkende fluid, rørledninger for innføring av vann avkjølt i den andre varmeveksler til lavtemperaturvanntanken (6) og lavtemperaturvanntilførselsmidler (7).
