Description

U9538 iU9538 i

Opfindelsen angår et luftkonditioneringsanlæg til køling af luften i rum i en bygning, såsom et enfamiliehus, og som har en fordamper med køleflade, en kompressor, en hovedkondensator og en reduktionsventil forbundet i et lukket kredsløb for et kølemiddel samt en blæser, der kan blæse luft igennem fordamperen, hvilken hovedkondensator udgøres af et i hovedsagen skrueformet rør, hvis vindinger er lagt rundt om en varmtvandsbeholder i berøring med dennes udvendige overflade, og hvilken hovedkondensator og varmtvandsbeholder udvendigt er forsynet med en isolering, såsom skumplast, og at smøreolien i kompressoren køles ved hjælp af en varmeveksler.The invention relates to an air conditioner for cooling the air in rooms of a building, such as a single-family house, and having a cooling evaporator, a compressor, a main capacitor and a reduction valve connected in a closed circuit for a refrigerant as well as a blower capable of blowing air. through the evaporator, which main capacitor is constituted by a generally helical tube, the windings of which are laid around a hot water container in contact with its external surface, and which main capacitor and hot water container are provided with an insulation such as foam plastic and that the lubricating oil in the compressor is cooled using a heat exchanger.

Fra tysk offentliggørelsesskrift nr. 2.619.722 kendes et varmepumpeanlæg, hvor vandet i en varmtvandsbeholder opvarmes af anlæggets kondensator, der i form af et rør er viklet om varmtvandsbeholderen, og hvor varmtvandsbeholderen med kondensator er omgivet af en isoleringskappe. Varmtvandsbeholderen og kondensatoren er af forskelligt materiale, idet kondensatorens rør er af kobber og således har en større varmeudvidel-seskoefficient end varmtvandsbeholderen, som antages at være af stål. Når vandet i beholderen opvarmes, vil der på kendt måde opstå en lagdeling, således at vandets temperatur vil variere mellem det øverste og nederste lag vand i beholderen, og varmt vand afledes for oven i beholderen. Har det kolde vand for neden i beholderen en temperatur på f.eks. 10°C og det varme vand for oven en temperatur på f.eks. 55°C, opstår der en temperaturdifferens på 45°C i beholderen. Denne lagdeling betyder, at beholdervæggens temperatur er forskellig i lodret retning, således at en kondensator bestående af kobberrør vil udvide sig væsentligt forskelligt fra bunden og opefter, idet kondensatorens rør udvider sig mere for oven end ved bunden, således at kondensatoren for oven løsgøres fra beholderen, hvorved en sikker overføring af varme fra kondensatorrøret via beholdervæggen til vandet i beholderen ikke kan finde sted.German publication specification No. 2,619,722 discloses a heat pump system in which the water in a hot water tank is heated by the condenser of the system, which in the form of a pipe is wound around the hot water tank and where the hot water tank with condenser is surrounded by an insulating jacket. The hot water tank and capacitor are of different material, the capacitor tube being of copper and thus having a greater coefficient of heat expansion than the hot water tank which is believed to be of steel. When the water in the container is heated, a layering will occur in known manner so that the temperature of the water will vary between the top and bottom layers of water in the container and hot water is discharged from above the container. Does the cold water below the container have a temperature of e.g. 10 ° C and the hot water above a temperature of e.g. 55 ° C, a temperature difference of 45 ° C occurs in the container. This layering means that the temperature of the container wall is different in the vertical direction, so that a capacitor consisting of copper tubes will expand substantially differently from the bottom upwards, with the capacitor tube expanding more at the top than at the bottom, so that the capacitor at the top is detached from the container. whereby a safe transfer of heat from the capacitor tube via the vessel wall to the water in the vessel cannot take place.

Formålet med opfindelsen er at anvise et luftkonditionerings- 149538 2 anlæg af den indledningsvis nævnte art, som kan fremstille en størst mulig mængde kold luft, især i det subtropiske eller tropiske klimabælte, på driftsikker måde.The object of the invention is to provide an air conditioning system of the kind mentioned above which can produce the greatest possible amount of cold air, especially in the subtropical or tropical climate belt, in a reliable manner.

Luftkonditioneringsanlægget ifølge opfindelsen er ejendommeligt ved, at hovedkondensatoren og varmtvandsbeholderen er fremstillet af materiale med sanme varmeudvidelseskoefficient,især stål, og at varmeveksleren til afkøling af kompressorens smøreolie er udformet som en oliekølingskondensator, som er anbragt uden på varmtvandsbeholderen i berøring med dennes udvendige overflade og er fremstillet af samme materiale som hovedkondénsa-toren og varmtvandsbeholderen. Ved en sådan udformning af anlægget vil varmtvandsbeholderen, hovedkondensatoren og oliekølingskondensatoren tilsammen udgøre en samlet enhed, hvis enkelte dele i en given afstand fra beholderens bund vil udvide sig ensartet under anlæggets drift, således at berøringen mellem hoved- og oliekølingskondensatorens rør og beholderens væg opretholdes. Herved muliggøres en sikker overføring af varme fra hoved- og oliekølingskondensatoren via beholderens væg til vandet i beholderen. Dette bevirker en optimal afkøling af fordamperen og kompressoren, hvilket medfører fremstilling af en størst mulig mængde kold luft på driftsikker måde, idet kompressorens levetid forlænges til mindst det dobbelte, når kompressoren bliver passende afkølet.The air conditioning system according to the invention is characterized in that the main condenser and the hot water tank are made of material with a gentle heat expansion coefficient, especially steel, and that the heat exchanger for cooling the compressor lubricating oil is designed as an oil cooling capacitor which is placed outside on the hot water container. made of the same material as the main condenser and hot water tank. In such a design of the system, the hot water tank, the main condenser and the oil cooling capacitor will together constitute a single unit whose individual parts at a given distance from the bottom of the container will expand uniformly during the operation of the system, so that the contact between the main and oil cooling capacitor and the wall of the container is maintained. This allows a safe transfer of heat from the main and oil cooling capacitor via the vessel wall to the water in the vessel. This results in optimum cooling of the evaporator and compressor, which results in the production of the greatest possible amount of cold air in a reliable way, extending the life of the compressor to at least twice when the compressor is suitably cooled.

Ifølge opfindelsen kan oliekølingskondensatoren udgøres af et i hovedsagen skrueformet rør, hvis vindinger er lagt rundt om varmtvandsbeholderen i berøring med dennes udvendige overflade, fortrinsvis således, at oliekølingskondensatorens vindinger ligger mellem hovedkondensatorens vindinger. Herved opnås en god berøring og dermed en god varmeledning mellem oliekølingskondensatoren og varmtvandsbeholderen.According to the invention, the oil cooling capacitor may be constituted by a generally helical tube, the windings of which are laid around the hot water container in contact with its external surface, preferably such that the windings of the oil cooling capacitor lie between the windings of the main capacitor. This provides a good touch and thus a good heat conduction between the oil cooling capacitor and the hot water tank.

Desuden kan ifølge opfindelsen hovedkondensatoren og oliekølingskondensatoren hver have en højde, som svarer til ca.Furthermore, according to the invention, the main capacitor and the oil cooling capacitor can each have a height corresponding to approx.

1/3 af varmtvandsbeholderens højde. Herved opnås, at varme-udvidelsen af hovedkondensatorens og oliekølingskondensato U9538 3 rens rør samt varmtvandsbeholderens væg begrænses til en passende størrelse.1/3 of the height of the hot water tank. Hereby, the heat expansion of the main condenser and oil cooling capacitor U9538 3 pipe as well as the wall of the hot water tank is limited to an appropriate size.

Endvidere kan ifølge opfindelsen varmtvandsbeholderen være fremstillet af en materialelegering, som har en større varme-ledningsevne end den materialelegering, der anvendes til hovedkondensatoren og oliekølingskondensatoren. Derved opnås, at den fra hovedkondensatoren og oliekølingskondensatoren afgivne varme straks ledes videre gennem varmtvandsbeholderens væg til vandet i beholderen.Furthermore, according to the invention, the hot water container may be made of a material alloy having a greater thermal conductivity than the material alloy used for the main capacitor and the oil cooling capacitor. In this way, the heat delivered from the main condenser and the oil cooling capacitor is immediately conveyed through the wall of the hot water tank to the water in the vessel.

Yderligere kan ifølge opfindelsen hovedkondensatorens og oliekølingskondensatorens rør have trekantet, firkantet eller ovalt tværsnit. Herved opnås en stor metallisk berøringsflade mellem hoved- og oliekølingskondensatorens rør og varmtvandsbeholderens udvendige overflade, hvilket giver en særlig god varmeledning mellem hoved- og oliekølingskondensatoren og varmtvandsbehoIderen.Furthermore, according to the invention, the tubes of the main condenser and the oil cooling capacitor may have a triangular, square or oval cross section. This results in a large metallic contact surface between the main and oil cooling capacitor pipes and the outside surface of the hot water tank, which provides a particularly good heat conduction between the main and oil cooling capacitor and the hot water tank.

Det i fig. 1 og 2 viste luftkonditioneringsanlæg er primært indrettet til ved luftudskiftning at køle luften i rum, f.eks. opholdsrum, i en bygning, såsom et enfamiliehus, en lejlighed eller lignende bolig. Den af luftkonditioneringsanlægget afkølede luft blæses via et kanalsystem ind i de rum, som ønskes kølet, og herfra suges luften ud via kanalsystemet bort gennem f.eks. et aftræk i taget eller recirkuleres, hvis det måtte ønskes.The FIG. 1 and 2, the air conditioning system is primarily adapted to cool the air in rooms, e.g. living spaces, in a building, such as a single-family house, apartment or similar dwelling. The air cooled by the air conditioning system is blown via a duct system into the rooms which are desired to be cooled, and from here the air is sucked out via the duct system through e.g. a vent in the roof or recirculated if desired.

Luftkonditioneringsanlægget er udformet som en opretstående kompakt enhed, som består af en forholdsvis stor nedre sektion la og en mindre øvre sektion Ib, som er aftageligt forbundet med den nedre sektion la. Sektionerne la og lb er hver fortrinsvis opbygget af en vinkeljernsramme, som er indkapslet af plader, idet sektionen la er opbygget af med hinanden forbundne vandrette og lodrette rammestænger 2a henholdsvis 2b af vinkeljern. På undersiden af de vandrette rammestænger 2a er fastgjort et antal stilleskruer 3. Foroven har luftkonditioneringsanlægget en topplade 4 (fig. 1 og 2), som er forsynet med en tilgangsåbning 5 for den luft, der skal køles, og. en afgangsåbning 6 for den luft, som er afkølet i luftkonditioneringsanlægget og er klar til at indblæses i rum i en bolig.The air conditioner is designed as an upright compact unit consisting of a relatively large lower section 1a and a smaller upper section 1b, which is removably connected to the lower section 1a. The sections 1a and 1b are each preferably constructed of an angle iron frame encased by plates, the section 1a being constructed of interconnected horizontal and vertical frame bars 2a and 2b, respectively of angular iron. On the underside of the horizontal frame rods 2a are fixed a number of setting screws 3. At the top, the air conditioning system has a top plate 4 (Figures 1 and 2), which is provided with an inlet opening 5 for the air to be cooled, and. an outlet opening 6 for the air which is cooled in the air conditioner and is ready to be blown into a room in a dwelling.

Som det fremgår af fig. 1 og af skemaet i fig. 6, har luft- 5 149538 konditioneringsanlægget en med køleflade forsynet fordamper 7, en kompressor 8, en hovedkondensator 9, en receiver 25, et tørfilter 26 og en reduktionsventil 27 i form af en termostatisk ekspansionsventil, som ved hjælp af forbindelsesledninger (fig. 6) er forbundet i et lukket kølekredsløb, hvori cirkuleres et kølemiddel, f.eks. freon 502. Luftkonditioneringsanlægget har endvidere en blæser 10, der kan blæse luft igennem fordamperen 7, og en lodret, centralt i den nedre sektion la anbragt varmtvandsbeholder 11. Udvendigt på varmtvandsbeholderen 11 er fastgjort en omtrent cirkulær bæreflange 11a af vinkeljern, som hviler oven på de lodrette rammestænger 2b, hvorved i hovedsagen undgås overføring af varme fra beholderen 11 til rammestængerne 2b. Som det ses af fig. 1, er blæseren 10, fordamperen 7 og kompressoren 8 anbragt i luftkonditioneringsanlæggets øvre sektion lb oven over varmtvandsbeholderen 11. Stilleskruerne 3 tjener til at indstille vinkeljernsrammen 2a, 2b således, at kompressoren 8 indtager en nøjagtig lodret stilling.As shown in FIG. 1 and of the diagram of FIG. 6, the air conditioner has a cooling evaporator 7, a compressor 8, a main capacitor 9, a receiver 25, a dry filter 26 and a reduction valve 27 in the form of a thermostatic expansion valve, which by means of connecting lines (Fig. 6 ) is connected in a closed cooling circuit in which a refrigerant, e.g. Freon 502. The air conditioner further has a blower 10 capable of blowing air through the evaporator 7, and a vertical, hot water tank 11. located centrally in the lower section 1a. An outer circular support flange 11a of angular iron resting on the outside of the the vertical frame bars 2b, thereby substantially avoiding the transfer of heat from the container 11 to the frame bars 2b. As seen in FIG. 1, the fan 10, the evaporator 7 and the compressor 8 are located in the upper section 1b of the air conditioning system above the hot water tank 11. The set screws 3 serve to adjust the angular frame 2a, 2b so that the compressor 8 takes an exact vertical position.

Hovedkondensatoren 9 udgøres af et i hovedsagen skrueformet rør, hvis vindinger er angivet med fuldstreg i fig. 1 og 3 og er lagt rundt om varmtvandsbeholderen 11 i berøring med dennes udvendige overflade. Hovedkondensatoren 9 og varmtvandsbeholderen 11 er udvendigt forsynet med en isolering 12 af f.eks. opskummet polyurethan eller lignende skumplast.The main capacitor 9 is constituted by a generally helical tube, the turns of which are indicated by a solid line in FIG. 1 and 3 and is placed around the hot water tank 11 in contact with its external surface. The main capacitor 9 and the hot water tank 11 are externally provided with an insulation 12 of e.g. foamed polyurethane or similar foam.

Den øvre sektion lb er forsynet med en isolering 12a af lignende materiale. Isoleringen 12 er på sin underside forsynet med et afløbsror 13 for kondensvand. På undersiden af isoleringen 12 er endvidere anbragt en studs 14 for et tilgangsrør 15 for koldt vand, der rager et kort stykke op i varmtvandsbeholderen 11, og en studs 16 for et afgangsrør 17 for varmt vand, der rager gennem varmtvandsbeholderen 11 næsten helt op til dennes øvre endebund.The upper section 1b is provided with an insulation 12a of similar material. The insulation 12 is provided on its underside with a drain pipe 13 for condensation water. Further, on the underside of the insulation 12 is provided a stud 14 for a cold water supply pipe 15 which projects a short distance up into the hot water tank 11 and a stud 16 for a hot water outlet pipe 17 which projects through the hot water tank 11 almost up to its upper end.

Ved drift af luftkonditioneringsanlægget indsuger blæseren 10 gennem tilgangsåbningen 5 den luft, som skal afkøles, og blæser den gennem den med køleflade forsynede fordamper 7 149538 6 og ud gennem afgangsåbningen 6, hvorfra den afkølede luft via et kanalsystem indblæses i de rum i boligen, som ønskes kølet. Ved luftens strømning langs fordamperen 7's køleflade sker der foruden en afkøling tillige en affugtning af luften, hvorfor der også vil ske en regulering af luftfugtigheden i boligen.In operation of the air conditioner, the fan 10 through the inlet opening 5 injects the air to be cooled and blows it through the cooled evaporator 7 and out through the outlet opening 6, from which the cooled air is blown into the rooms of the dwelling via a duct system. wanted to be chilled. In addition to cooling, the air flow along the cooling surface of the evaporator 7 also dehumidifies the air, which is why there will also be a regulation of the humidity in the home.

I det af fordamperen 7, kompressoren 8, hovedkondensatoren 9 og reduktionsventilen 27 dannede lukkede kølekredsløb vil kølemidlet i fordamperen 7 optage den fra luften afgivne varme og fordampe. Kølemiddeldampen ledes til kompressoren 8, hvor den komprimeres og derefter ledes til hovedkondensatoren 9, hvor kølemiddeldampen kondenseres under afgivelse af varme.In the closed cooling circuit formed by the evaporator 7, the compressor 8, the main capacitor 9 and the reduction valve 27, the refrigerant in the evaporator 7 will absorb the heat and evaporate delivered from the air. The refrigerant vapor is fed to the compressor 8 where it is compressed and then passed to the main capacitor 9, where the refrigerant vapor is condensed during heat release.

Den kondenserede kølemiddelvæske ledes derefter til receiveren 25 og herfra videre gennem tørfilteret 26. Dernæst ledes kølemiddelvæsken til reduktionsventilen 27 og gennem denne ventil under et stort trykfald og strømmer ved lavt tryk tilbage til fordamperen 7, hvormed kredsprocessen er sluttet.The condensed coolant liquid is then passed to the receiver 25 and thence through the dry filter 26. Next, the coolant liquid is fed to the reduction valve 27 and through this valve under a large pressure drop and flows back to the evaporator 7 at low pressure with which the circuit process is closed.

Den varme, som kondensatoren 9 afgiver ved varmeledning gennem varmtvandsbeholderen 11’s væg til vandet i beholderen 11, bidrager til at opvarme vandet i varmtvandsbeholderen 11, således at det varme vand kan anvendes som varmt brugsvand.The heat that the capacitor 9 produces by heat conduction through the wall of the hot water tank 11 to the water in the container 11 contributes to heating the water in the hot water tank 11, so that the hot water can be used as hot tap water.

Den således fremstillede mængde af varmt brugsvand, som hidrører fra afkølingen af luften i fordamperen 7, har en sådan størrelse, at den rigeligt dækker en normal families forbrug af varmt vand. Det varme vand aftappes fra afgangsrøret 17.The amount of hot domestic water thus produced, resulting from the cooling of the air in the evaporator 7, is of such size as to adequately cover the consumption of hot water by a normal family. The hot water is drained from the outlet pipe 17.

Kompressoren 8's smøreolie køles ved hjælp af en varmeveksler i form af en oliekølingskondensator 18 (fig. 1, 3 og 6).The lubricating oil of compressor 8 is cooled by means of a heat exchanger in the form of an oil cooling capacitor 18 (Figures 1, 3 and 6).

Hovedkondensatoren 9 og varmtvandsbeholderen 11 er fremstillet af samme materialetype, især stål, og oliekølingskondensatoren 18 er anbragt uden på varmtvandsbeholderen 11 i berøring med dennes udvendige overflade og er fremstillet af samme materialetype som hovedkondensatoren 9 og varmtvandsbeholderen 11. Ved en sådan udformning af anlægget vil varmt 7 149538 vandsbeholderen 11, hovedkondensatoren 9 og oliekølingskondensatoren 18 tilsammen udgøre en samlet enhed, hvis enkelte dele i en given afstand fra beholderen 11's bund vil udvide sig ensartet under anlæggets drift, således at berøringen mellem hoved- og oliekølingskondensatoren 9, 18's rør og beholderen 11's væg opretholdes. Herved muliggøres en sikker overføring af varme fra hoved- og oliekølingskondensatoren 9, 11 via beholderen 11's væg til vandet i beholderen 11.The main capacitor 9 and the hot water tank 11 are made of the same material type, especially steel, and the oil cooling capacitor 18 is placed outside on the hot water tank 11 in contact with its external surface and is made of the same material type as the main condenser 9 and the hot water tank 11. 7, the water tank 11, the main capacitor 9 and the oil cooling capacitor 18 together constitute a single unit whose individual parts at a given distance from the bottom of the container 11 will expand uniformly during the operation of the system, so that the contact between the main and oil cooling capacitor 9, 18 and the container 11 wall is maintained. This allows a safe transfer of heat from the main and oil cooling capacitor 9, 11 via the wall of the container 11 to the water in the container 11.

Dette bevirker en optimal afkøling af fordamperen 7 og kompressoren 8, hvilket medfører fremstilling af en størst mulig mængde kold luft, især i det subtropiske eller tropiske klimabælte, på driftsikker måde, idet kompressoren 8's levetid forlænges til mindst det dobbelte, når kompressoren 8 bliver passende afkølet. Endvidere opnås, at den af smøreolien afgivne varme udnyttes, nemlig til opvarmning af brugsvandet i varmtvandsbeholderen 11, hvilket giver en energibesparelse.This results in optimal cooling of the evaporator 7 and compressor 8, which results in the production of the greatest possible amount of cold air, especially in the subtropical or tropical climate belt, in a reliable way, extending the life of the compressor 8 to at least twice as the compressor 8 becomes suitable cooled. Furthermore, it is obtained that the heat supplied by the lubricating oil is utilized, namely for heating the hot water in the hot water tank 11, which gives an energy saving.

Under drift af et luftkonditioneringsanlæg med indkoblet oliekølingskondensator 18 som vist i fig. 6, vil kompressoren 8 sende komprimeret kølemiddelgas over i hovedkondensatoren 9. Her afkøles gassen, hvorved denne delvis kondenserer. Blandingen af gas og kondensat ledes gennem kompressoren 8's oliekølingsspiral 28, hvor det fordamper og optager varme fra kompressoren 8. I oliekølingskondensatoren 18 finder den endelige kondensation sted, og kondensatet opsamles i receiveren 25.During operation of an air conditioner with coupled oil cooling capacitor 18 as shown in FIG. 6, the compressor 8 will send compressed refrigerant gas into the main capacitor 9. Here the gas is cooled, whereby it partially condenses. The mixture of gas and condensate is passed through the oil cooling coil 28 of the compressor 8, where it evaporates and absorbs heat from the compressor 8. The final condensation takes place in the oil cooling capacitor 18 and the condensate is collected in the receiver 25.

Oliekølingskondensatoren 18 udgøres af et i hovedsagen skrueformet rør, hvis vindinger er angivet med punkteret streg i fig. 1 og 3 og er lagt rundt om varmtvandsbeholderen 11 i berøring med dennes udvendige overflade, fortrinsvis således, at oliekølingskondensatoren 18's vindinger ligger mellem hovedkondensatoren 9's vindinger. Herved opnås en god berøring og dermed en god varmeledning mellem oliekølingskondensatoren 18 og varmtvandsbeholderen 11.The oil cooling capacitor 18 is constituted by a generally helical tube, the turns of which are indicated by a dashed line in FIG. 1 and 3 and is disposed around the hot water tank 11 in contact with its external surface, preferably such that the windings of the oil cooling capacitor 18 lie between the windings of the main capacitor 9. This results in good contact and thus a good heat conduction between the oil cooling capacitor 18 and the hot water tank 11.

Hovedkondensatoren 9 og oliekølingskondensatoren 18 har hver 149538 8 fortrinsvis en højde, som svarer til ca. 1/3 af varmtvandsbeholderen 11's højde. Herved opnås, at varmeudvidelsen af hovedkondensatoren 9's og oliekølingskondensatoren 18's rør samt varmtvandsbeholderen 11's væg begrænses til en passende størrelse.The main capacitor 9 and the oil cooling capacitor 18 each preferably have a height corresponding to approx. 1/3 of the height of the hot water tank 11. Hereby the heat expansion of the pipe of the main capacitor 9 and the oil cooling capacitor 18 as well as the wall of the hot water tank 11 is limited to a suitable size.

Varmtvandsbeholderen 11 kan hensigtsmæssigt være fremstillet af en materialelegering, som har en større varmeledningsevne end den materialelegering, der anvendes til hovedkondensatoren 9 og oliekølingskondensatoren 18. Herved opnås, at den fra hovedkondensatoren 9 og oliekølingskondensatoren 18 afgivne varme straks ledes videre gennem varmtvandsbeholderen 11's væg til vandet i beholderen 11.Conveniently, the hot water tank 11 may be made of a material alloy having a greater thermal conductivity than the material alloy used for the main capacitor 9 and the oil cooling capacitor 18. Hereby, the heat delivered from the main condenser 9 and the oil cooling capacitor 18 to the heat water supplied to the hot water tank 11 is immediately supplied. in the container 11.

Hovedkondensatoren 9's og oliekølingskondensatoren 18's rør kan have trekantet, firkantet eller ovalt tværsnit. Herved opnås en stor metallisk berøringsflade mellem hoved- og oliekølingskondensatoren 9, 18's rør og varmtvandsbeholderen 11's udvendige overflade, hvilket giver en særlig god varmeled-ning mellem hoved- og oliekølingskondensatoren 9, 18 og varmtvandsbeholderen 11.The tubes of the main capacitor 9 and the oil cooling capacitor 18 may have a triangular, square or oval cross section. This results in a large metallic contact surface between the main and oil cooling capacitor 9, 18 and the outside surface of the hot water tank 11, which provides a particularly good heat conduction between the main and oil cooling capacitor 9, 18 and the hot water tank 11.

Fordamperen 7 kan med fordel være en lamelfordamper. Herved opnås en fordamper med forholdsvis stor køleflade, som kan optage store varmemængder fra luften pr. tidsenhed.Evaporator 7 may advantageously be a slat evaporator. This results in an evaporator with a relatively large cooling surface, which can absorb large amounts of heat from the air per room. unit of time.

Forneden på varmtvandsbeholderen 11's afgangsrør 17 for varmt vand er anbragt en motorventil 19 til sikring af, at temperaturen af det varme vand i varmtvandsbeholderen 11 ikke overstiger en forud fastlagt temperatur, f.eks. 55°C.A motor valve 19 is provided at the bottom of the hot water outlet pipe 17 for hot water to ensure that the temperature of the hot water in the hot water tank 11 does not exceed a predetermined temperature, e.g. 55 ° C.

En sådan motorventil 19 er fordelagtig under visse klimatiske forhold med megen varme, hvor en overproduktion af varmt vand ofte vil indtræde, dvs. når vandet i varmtvandsbeholderen 11 er nået op til den forud fastlagte temperatur, og der ikke forbruges vamt vand. I dette tilfælde aktiveres motorventilen 19, således at den er åben i et forud fastlagt tidsrum, hvorved en del varmt vand gennem afgangsrøret 9 149538 17 ledes bort fra beholderen 11 samtidigt med, at der gennem tilgangsrøret 15 tilføres koldt vand i beholderen 11, således at temperaturen af vandet i beholderen 11 falder.Such a motor valve 19 is advantageous under certain climatic conditions with excessive heat, where overproduction of hot water will often occur, ie. when the water in the hot water tank 11 has reached the predetermined temperature and no hot water is consumed. In this case, the engine valve 19 is activated so that it is open for a predetermined period of time, whereby some hot water through the outlet pipe 9 is discharged from the container 11 while at the same time, through the supply pipe 15, cold water is supplied to the container 11, so that the temperature of the water in the container 11 decreases.

Vandet i beholderen 11 er derefter klar til igen at optage varme fra hovedkondensatoren 9 og oliekølingskondensatoren 18. Motorventilen 19 kan hensigtsmæssigt aktiveres automatisk af et signal fra en temperaturføler 20, som er anbragt ved toppen af varmtvandsbeholderen 11. Det bortledte varme vand kan f.eks. anvendes i svømmebassiner eller lignende eller for lejligheders vedkommende tilsluttes et centralt varmtvandsforsyningsanlæg.The water in the container 11 is then ready to re-absorb heat from the main capacitor 9 and the oil cooling capacitor 18. Conveniently, the motor valve 19 can be automatically activated by a signal from a temperature sensor 20 located at the top of the hot water tank 11. The discharged hot water can e.g. . used in swimming pools or the like or for apartments, a central hot water supply system is connected.

Luftkonditioneringsanlægget kan styres elektronisk fra et hensigtsmæssigt på luftkonditioneringsanlæggets forside anbragt kontrolpanel 21 (fig. 1 og 2), hvorpå bl.a. temperaturen af det varme brugsvand og luftudskiftningshastigheden kan indstilles.The air conditioner can be controlled electronically from a convenient control panel 21 (Figs. 1 and 2), which is arranged on the front of the air conditioner. the temperature of the hot water and the air exchange rate can be set.

I fig. 4 og 5 er vist en anden udførelsesform for luftkonditionering s anlægget, og i fig. 7 er vist et skema for det tilhørende kølekredsløb. Den anden udførelsesform adskiller sig fra den i fig. 1 viste udførelsesform ved, at der oven over fordamperen 7 og blæseren 10 er anbragt henholdsvis en sekundær fordamper 22 og en sekundær blæser 23. Luftkonditioneringsanlægget i fig. 4 har desuden foroven en topplade 24, som er forsynet med fire åbninger 29, 30, 31 og 32 (fig. 5).In FIG. 4 and 5, another embodiment of the air conditioning system is shown, and in FIG. 7 is a diagram of the associated cooling circuit. The second embodiment differs from that of FIG. 1 in that a secondary evaporator 22 and a secondary blower 23. are arranged above the evaporator 7 and the fan 10 respectively. The air conditioning system of FIG. 4 also has a top plate 24 at the top, which is provided with four openings 29, 30, 31 and 32 (Fig. 5).

Den sekundære blæser 23 kan gennem den sekundære fordamper 22 blæse varm luft ind i en boligs rum, efter at varmtvandsforsyningen er dækket. Et sådant anlæg er hensigtsmæssigt, når vejret er koldt. Når temperaturen af vandet i varmtvandsbeholderen 11 er nået op til en forud fastlagt temperatur, f.eks. 55°C, skifter kølekredsløbet ved hjælp af en trevejsventil 35 (fig. 7) fra hovedkondensatoren 9 til den sekundære fordamper 22, der nu virker som kondensator, og den sekundære blæser 23 starter med at blæse varm lufb ind i bygningen gennem luftkonditioneringskanalerne. Tapper man nu varmt vand fra varmtvandsbeholderen 11, standser indblæs-ningen af varm luft, og indblæsningen starter først igen, • når den forud indstillede temperatur af vandet i beholderen II er nået.The secondary fan 23 can, through the secondary evaporator 22, blow hot air into a room's room after the hot water supply is covered. Such a plant is appropriate when the weather is cold. When the temperature of the water in the hot water tank 11 has reached a predetermined temperature, e.g. 55 ° C, the cooling circuit shifts by means of a three-way valve 35 (Fig. 7) from the main capacitor 9 to the secondary evaporator 22, which now acts as a capacitor, and the secondary blower 23 starts by blowing hot air into the building through the air conditioning ducts. If hot water is now drained from the hot water tank 11, the supply of hot air stops, and the blowing starts again only when the preset temperature of the water in the container II is reached.
