Abstract

Primary water enters the circuit from a remote heating system, and is fed to two user water exchangers (20,21) via a conduit (8). The two units are series-coupled and freely located in a common casing (9). The radiator exchange unit (22) is fitted around the casing (9), and is connected to the primary water via a pipe (23). Primary water is fed to one of the user water exchangers (21) via the casing, and then flows through it. To the connecting conduit between the two hot water exchangers is a conduit for heat exchange circulation, and comprising a pipe with small dia. joined to the connecting conduit (25), and a second pipe inserted in the first via an aperture in the casing, and having a dia. permitting the two pipes to be soldered together. Around the second pipe is fitted a cone, directly welded to the casing, and soldered to the second pipe at a point apart from that where the two pipes are soldered together.

Description

460 1so ¿ Primärvatten pàföres även varmvattenenheten 12 och den i serie därmed kopplade enheten 11. Kallvatten ankommer vid 5 och värmas i enheterna 11 och 12, och förbrukningsvarmvatten uttages vid 6. 13 är en termostat, vars utsignal pâföres en reglerenhet 14 för förbrukningsvarmvatten, och som styr en ventil 19 i ledningen mellan enheterna 11 och 12. 'm- Primärvatten, som passerar enheten 10, påföres enheten 11 (tvåstegskopp- ling). 7 är en varmvattencirkulationskrets (VVC) för upprätthållande av temperaturen i systemet. ansluten till enheten 12. 2 är utgående primär- vatten. 460 1so ¿Primary water is also applied to the hot water unit 12 and the series 11 connected thereto. Cold water arrives at 5 and is heated in the units 11 and 12, and consumption hot water is taken out at 6. 13 is a thermostat, the output of which is applied to a control unit 14 which controls a valve 19 in the line between the units 11 and 12. 'm- Primary water, which passes the unit 10, is applied to the unit 11 (two-stage connection). 7 is a hot water circulation circuit (VVC) for maintaining the temperature in the system. connected to unit 12. 2 is outgoing primary water.

Radiatorenheten 10 kan avstängas medelst ventilen 17.The radiator unit 10 can be switched off by means of the valve 17.

Vid anordningar enligt uppfinningen (figur 2) inkommer primärvatten från fjärrvärmesystemet vid 1 och pàföres förbrukningsvattenenheterna 20 och 21 via ledningen 8. Enheterna 20 och 21 är seriekopplade och frilagda inom ett gemensamt hölje 9. Primärvatten avgår vid 2.In devices according to the invention (figure 2), primary water enters from the district heating system at 1 and the consumption water units 20 and 21 are applied via the line 8. The units 20 and 21 are connected in series and exposed within a common housing 9. Primary water departs at 2.

Radiatorenheten 22 är anordnad kring höljet 9 och är ansluten till primär- vattnet via ledningen 23. Radiatorkretsen visas vid 3-4, och primärvattnet pàföres enheten 21 via höljet 9 vid 24. och genomflyter därefter enheten 21.The radiator unit 22 is arranged around the housing 9 and is connected to the primary water via the line 23. The radiator circuit is shown at 3-4, and the primary water is applied to the unit 21 via the housing 9 at 24. and then flows through the unit 21.

VVC-enheten 7 är ansluten vid höljets mitt 25 i form av ett rör. (Se vidare figur 3.) 26 är en ventil i primärvattenkretsen, styrd från en reglerenhet 27, vilken är anordnad att motta utsignaler från en termostat 28 i radiatorkretsen.The HVAC unit 7 is connected to the center 25 of the housing in the form of a tube. (See also figure 3.) 26 is a valve in the primary water circuit, controlled from a control unit 27, which is arranged to receive output signals from a thermostat 28 in the radiator circuit.

Kallvatten införas vid 31 och värmas i enheterna 20, 21 och förbruknings- varmvatten uttages vid 32. 30 är en termostat i nämnda varmvattenledning och dess utsignal pàföres en reglerenhet 29, vars utsignal pàföres en ventil 33 i primärledningen 8. 34 är en utetermostat. Enheterna 20, 21 är placerade ovanpå varandra inom höljet 9.Cold water is introduced at 31 and heated in the units 20, 21 and consumption hot water is taken out at 32. 30 is a thermostat in said hot water line and its output signal is applied to a control unit 29, the output of which is applied to a valve 33 in the primary line 8. 34 is an outdoor thermostat. The units 20, 21 are placed on top of each other within the housing 9.

Som synes blir hela värmeväxlaren kompakt och rördragningen minimal, bl a kopplingarna mellan de olika enheterna 20, 21, 22, Anordningen enligt ovan kan varieras på màngahanda sätt inom ramen för te nedanstående patentkrav.As can be seen, the entire heat exchanger becomes compact and the piping is minimal, including the connections between the various units 20, 21, 22. The device as above can be varied in many ways within the scope of the following claims.
