Claims (7)

1. Kølemiddelscyklusapparat omfattende: mindst en kompressor (1), en radiator (2), dekompressionsorgan (3) der er i stand til at ændre en åbningsgrad, en varmeabsorber (4), en intern varmeveksler (5) der udfører varmeveksling mellem et kølemiddel ved en udgang på radiatoren (2) og kølemidlet ved en udgang på varmeabsorberen (4), hvor et andet temperaturdetektionsorgan (31) til at detektere en kølemiddelstemperatur mellem en udgang på radiatoren (2) og en højtrykssideindgang på den interne varmeveksler (5) og internt varmevekslerudgangstemperaturdetektionsorgan (52) til at detektere kølemiddelstemperaturen mellem en højtrykssideudgang på den interne varmeveksler (5) og en indgang på kompressionsorganet (3) er tilvejebragt, kendetegnet ved at en åbningsgrad på dekompressionsorganet (3) styres således at en temperaturforskel (AThx) mellem en detektionstemperatur ved det andet temperaturdetektionsorgan (31) og detektionstemperaturen ved det interne varmevekslerudgangstemperaturdetektionsorgan (52) bliver en målværdi.
2. Kølemiddelscyklusapparat ifølge krav 1, hvor sjette temperaturdetektionsorgan (33) til at detektere kølemiddelstemperaturen mellem en lavtrykssideudgang på den interne varmeveksler (5) og en indgang på kompressoren (1) tilvejebringes, overophedningsgraden på en kompressorsugedel beregnes ud fra en kølemiddelsmætningstemperatur ved et detektionspunkt på det sjette temperaturdetektionsorgan (33) og en detektionstemperatur ved det sjette temperaturdetektionsorgan (33), og åbningsgraden på dekompressionsorganet (3) styres således at overophedningsgraden bliver målværdien.
3. Kølemiddelscyklusapparat ifølge krav 2, hvor andet trykdetektionsorgan (51) tilvejebringes mellem lavtrykssideudgangen på den interne varmeveksler (5) og indgangen på kompressoren (1) og kølemiddelsmætningstemperaturen beregnes baseret på en detektionsværdi af det andet trykdetektionsorgan (51).
4. Kølemiddelscyklusapparat ifølge krav 2, hvor femte temperaturdetektionsorgan (32) tilvejebringes mellem indgangen på varmeabsorberen (4) og lavtrykssideindgangen på den interne varmeveksler (5) og kølemiddelsmætningstemperaturen beregnes baseret på detektionstemperaturen i det femte temperaturdetektionsorgan (32).
5. Kølemiddelscyklusapparat ifølge et hvilket som helst af kravene 2 til 4, hvor det prioriteres at styre overophedningsgraden over temperaturforskellen.
6. Kølemiddelscyklusapparat ifølge et hvilket som helst af kravene 1 til 5, hvor radiatoren (2) er en varmeveksler der veksler varme med vand.
7. Kølemiddelscyklusapparat ifølge et hvilket som helst af kravene 1 til 5, hvor carbondioxid anvendes som et kølemiddel.
