Description

l5 ss' 8005384-6 medium vilket tjänar till uppvärmning exempelvis av en byggnad och.kan utgöras-av cirkulerande vatten. l5 ss' 8005384-6 medium which serves for heating, for example, a building and can be constituted by circulating water.

Med hänvisning även till FIG 2 innefattar värme- växlaren-l3 en yttermantel l4, som lämpligen består av en PVC-slang, exempelvis sådan svart PVC-slang, som an- g vändes till vattenledningar. Ett externt medium, exempel- vis grundvatten, som pumpas upp ur marken och håller en temperatur pâ 5 ä 8 °C, tillföres yttermanteln l4 i dennas ena ände vid l5 och avgår från yttermanteln i dennas andra ände vid l6 för att åter infiltreras i marken. I stället för grundvatten kan annan värmebärande vätska cirkuleras genom yttermanteln l4, exempelvis vätska från solfångare, vatten, som upptagit spillvärme, eller vatten från ett fjärrvärmenät.Referring also to FIG. 2, the heat exchanger-13 comprises an outer jacket 14, which suitably consists of a PVC hose, for example such a black PVC hose, which was used for water pipes. An external medium, for example groundwater, which is pumped out of the ground and maintains a temperature of 5 to 8 ° C, is fed to the outer jacket 14 at one end thereof at 15 and departs from the outer jacket at its other end at 16 to infiltrate the ground again. . Instead of groundwater, other heat-carrying liquid can be circulated through the outer jacket 14, for example liquid from solar panels, water that has absorbed waste heat, or water from a district heating network.

Den inuti yttermanteln anordnade värmeväxlaren l2 innefattar ett rör l7, som har ändväggar l8 och l9 och sålunda är helt slutet mot yttermantelns 14 inre. Koaxiellt inuti röret l7 är anordnat ett andra rör 20, som går in genom ändväggen l8 och slutar med en öppen ände 2l på nâ- got avstånd från ändväggen l9. Till röret 20 är ansluten en ledning 22, som kommer från kondensorn ll, och till röret 17 är i den ände, där ändväggen l8 är anordnad, an- sluten en ledning 23 vid en på röret anordnad stuts 24, och denna ledning 23 går till kompressorn l0 på dennas sugsida. I ' I ett typiskt utförande av värmeväxlaren enligt upp- finningen har yttermanteln l4 en längd av storleksordningen. l5 m och en invändig diameter på ca 40 mm. Röret l7 sträcker sig nästan över längden av yttermanteln l4 och har en in- vändig diameter på ca l9 mm, medan röret 20 har en invän- dig diameter på 4,7 å 4,8 mm.The heat exchanger 12 arranged inside the outer jacket comprises a tube 17, which has end walls 16 and 19 and is thus completely closed to the interior of the outer jacket 14. Coaxially inside the tube 17 is arranged a second tube 20, which enters through the end wall 18 and terminates with an open end 21 at some distance from the end wall 19. Connected to the tube 20 is a conduit 22, which comes from the condenser 11, and to the tube 17 is at the end, where the end wall 18 is arranged, a conduit 23 is connected to a socket 24 arranged on the tube, and this conduit 23 goes to the compressor l0 on its suction side. In a typical embodiment of the heat exchanger according to the invention, the outer jacket 14 has a length of the order of magnitude. l5 m and an inside diameter of about 40 mm. The tube 17 extends almost over the length of the outer jacket 14 and has an inner diameter of about 19 mm, while the tube 20 has an inner diameter of 4.7 to 4.8 mm.

Köldmedievätska tillföras röret 20 från ledningen 22 vid en temperatur på exempelvis 40 ä 50 °C och kyles 'i röret 20 till en förångningstemperatur på l0_- -20 °C.Refrigerant liquid is supplied to the pipe 20 from the line 22 at a temperature of, for example, 40 to 50 ° C and is cooled in the pipe 20 to an evaporation temperature of 10 to -20 ° C.

Köldmedievätskan avgår under förångning vid rörets 20 ände 2l till röret l7 och passerar under upptagning av värme. från det genom yttermanteln 14 passerande externa mediet i motsatt strömningsriktning mot köldmedievätskan i röret och det externa mediet i innermanteln l4 till ledningen ...e m.. ~.-.4...........l .W _. 23 för att på nytt sugas in och komprimeras av kompres- sorn 10. _ Värmeväx1aren 13 kan också vara förlagd i marken för värmeväx1ing me11an kö1dmediet och omgivningen. I så fa11 kan det externa mediet i mante1n 14 vara sti11astå- ende och utgöres Iämpïigen av vatten. När kompressorn är igång, kanske någon timme per dygn, kommer vattnet i ytter- mantein 14 att frysa ti11 is pga att kö1dmediet tar sitt förångningsvärme från vattnet. Denna frysning kan ti11âtas, när yttermante1n 14 består av ett pïaströr, som kan ge efter utan att skadas vid expansionen under frysningen.The refrigerant liquid evaporates during evaporation at the end 21 of the tube 20 to the tube 17 and passes during the absorption of heat. from the external medium passing through the outer jacket 14 in the opposite flow direction to the refrigerant liquid in the pipe and the external medium in the inner jacket 14 to the line ... e m .. ~ .-. 4 ........... l .W _. 23 to be re-sucked in and compressed by the compressor 10. The heat exchanger 13 may also be located in the ground for heat exchange between the meat medium and the environment. In that case, the external medium in the mantle 14 may be stagnant and is suitably composed of water. When the compressor is running, perhaps for an hour per day, the water in the outer tank 14 will freeze to ice due to the meat medium taking its evaporating heat from the water. This freezing can be tolerated when the outer mantle 14 consists of a pie tube which can yield without being damaged during the expansion during freezing.

Under resterande dei av dygnet smäites sedan isen i ytter- mante1n 14 genom att jordvärme ti11föres från den omgi- vande marken.During the rest of the day, the ice in the outer 14 is then smelted by applying geothermal heat from the surrounding ground.

Den genom röret 20 ti11förda köidmedievätskan ky1es från det omgivande köïdmediet i röret 17 under sin ström- ning genom detta rör ti11 den öppna änden 21, där köid- medievätskan förângas och går in i röret 17, och genom denna ky1ning av den tiïlförda kö1dmedievätskan torde den ovan beskrivna effekten uppnås, innebärande att fïödet av köldmedievätska anpassas efter mängden ti11fört värme.The coolant supplied through the tube 20 is cooled from the surrounding cooling medium in the tube 17 during its flow through this tube to the open end 21, where the coolant liquid evaporates and enters the tube 17, and by this cooling of the supplied coolant liquid it should the effect described above is achieved, meaning that the flow of refrigerant liquid is adapted to the amount of heat supplied.
