For detta andamM bringas luft frail lokalen me-deist en Mit 10 att pasSera en krets 12, som enligt fig. 1-7 b8rj ar och slutar i lokalen. I denna krets är enligt fig. 1 inkopplad en fuktvaxlare 14, en varmevaxlare 16 och alum en fuktvaxlare 18, vilka i fur och ordning genomstrommas av den fran lokalen kommande luften. I fuktvaxlarna ager en overforing a-v fukt rum gentemot en ytterluftstrom, som passerar ett kretslopp 20, och i varmevaxlaren en varmeoverfOring gentemot en annan ytterluftstrom, som passerar ett kretslopp 22. The devices shown in the figures have the task of conditioning the air in a room during a hot outdoor climate, ie. In the room, not only is the temperature lower than that of the outside air maintained, but at the same time moisture must be removed from the room, so that the air in it can be comfortable to stay in. For this purpose, air is brought from the room with a Mit 10 to pass. a circuit 12, which according to Figs. 1-7 starts and ends in the room. In this circuit, according to Fig. 1, a moisture exchanger 14, a heat exchanger 16 and alum a moisture exchanger 18 are connected, which in turn are flowed through by the air coming from the room. In the moisture exchangers a transfer of moisture takes place relative to an outer air stream which passes a circuit 20, and in the heat exchanger a heat transfer to another outer air stream which passes a cycle 22.

En fuktvaxlare enligt uppfinningen har salunda till uppgift att formedla en transport av fukt frail den ena luftstrommen till den and- 2 ra. Den är av det slag, som i minsta mojliga grad samtidigt overfor varme mellan medierna.

A moisture exchanger according to the invention thus has the task of mediating a transport of moisture from one air stream to the other. It is of the kind that, as far as possible, at the same time confronts heat between the media. The moisture exchanger is of the regenerative type with an exchanger body which moves in a closed path, during which its individual portions alternately undergo the hot cycles in which the moisture exchanger is connected. The moisture-transferring mass is preferably in the form of air-thin trades or even better layers of foils or Mad. Furthermore, they are of the continuously operating type, although moisture exchangers can be used, which work intermittently, and where the exchanger body can consist of two absorbent elements, one of which is in function for absorbing moisture, while one is regenerated.

Apparat ens verkningssatt skall i det foljande klarlaggas med hj0lp air Mollier-diagrammet enligt fig. 8. Det antages att ytterluften: liar tillstandet 44 enligt thagramrnet, som motsvarar en temperatur av 35° C och en relativ fukthalt i luften av %. Luft av denna art infores salunda genom, intaget 30 och flakten 38. The apparatus even in operation shall in the following be clarified with the aid of the air Mollier diagram according to Fig. 8. It is assumed that the outside air: reads the state 44 according to the diagram, which corresponds to a temperature of 35 ° C and a relative humidity in the air of%. Air of this kind is thus introduced through, inlet 30 and flake 38.

I det foljande kommer att vid hanvisningen till olika punkter i .cliagrammen efter deras sifferbeteckning angivas inom parentes det for punkten radande tillstandet i avseende pa temperaturen i °G och den relativa fukthalten i proeent. Temperaturvardena hava omraknats frill diagram, som angiva ternperaturen i Fahrenheit, varvid i de fiesta fall celsiustaIen ,avrundats till narmaste halv grad. In the following, when referring to different points in the cliagrams according to their numerical designation, the condition prevailing for the point with respect to the temperature in ° C and the relative moisture content in percent will be indicated in parentheses. The temperature values have been recalculated according to diagrams, which indicate the temperature in the Fahrenheit, where in most cases the Celsius steel has been rounded to the nearest half degree.

Innerluften av tillstandet 46 enligt diagram-met avgiver i fuktvaxlaren 14 fukt till luften I kretsen 20 under en tillstandsandring, f Orlopande tangs entalpilinjen 50 och naende punkten 52, (48°, c:a 4 %). Genom sorption av fukt fran rumsluften till fuktvaxlaren 14 her salunda samtidigt temperaturen stegrats. I varmevaxlaren 16 ager i kretsen 22 en varmevaxling rum mot ytterluft, som i diagram-met foljer den med ,abskissan parallella linjen 54. Efter varinevaxlaren har innerluften tillstandet 56 (36°, c:a 7 %). Enligt diagram-met her fuktinnehallet antagits fOrbliva oforandrat. Vid foreliggande utforingsform far innerluften slutligen passera fuktvaxlaren 18, dar en tillstandsandring sker langs entalpilinjen 58 till punkten 48 (18°, 70 %), vilket innebar att en avdunstning av fukt agt rum till innerluften. Innerluften her vid sluttillstandet 48 lagre ,absolut fuktinnehill och i detta fall aven lagre temperatur an vid begynnelsetillstandet 46. The indoor air of the condition 46 according to the diagram in the humidity exchanger 14 emits moisture to the air in the circuit 20 during a state change, f The orbital tangent arrow line 50 and reaching the point 52, (48 °, about 4%). By sorption of moisture from the room air to the moisture exchanger 14, the temperature is thus simultaneously increased. In the heat exchanger 16, in the circuit 22, a heat exchange space acts towards the outside air, which in the diagram follows it with the abscissa parallel line 54. After the heat exchanger, the inner air has the state 56 (36 °, approx. 7%). According to the diagram, the moisture content is assumed to remain unchanged. In the present embodiment, the inner air is finally allowed to pass the moisture exchanger 18, where a state change takes place along the singular arrow line 58 to the point 48 (18 °, 70%), which meant that a evaporation of moisture takes place to the inner air. The indoor air here at the final state 48 is lower, absolute moisture content and in this case also lower temperature than at the initial state 46.

Ytterluften i kretsen 20 har omedelbart 10-re fuktva.xlaren 14 givits tillstandet 60 i diagrammet (89°, c:a 3,5 %) pa satt som i det foljande narmare skall klarlaggas. Densam- 3 mas fuktvaxling med innerluftstrommen representeras av entalpilinjen 62, varvid fuktinnehallet Ras till punkten 64 (470, 47 %) som ligger p. hogre temperatur an ytterluften enligt punkten 44. Det dr darfor mejligt att kyla ytterluften i kretsen 20 enligt linjen 66 till punkten 68 (36°, 82 %) i varmevaxlaren 32, varvid varmevaxlingen sker mot ytterluft, som passerar kanalsystemet 40. Den ytterluft, som harvid utnyttj as, overfores fran tillstandet 44 langs linjen 70 till tillstandet 72 (46°, 23 %). Del absoluta fuktinnehallet i punkten 68 är sasom av diagrammet framgar Mgt och nedbringas darfor genom utspadning med farsk ytterluft via intaget 30 och uttaget 28. Deana utspadning ger en tillstandsandring ,enligt den med ordinatan parallella linjen 74 till punkten 76 (36°, 72 %),. Av diagrammet framgar att den relativa fukthalten i punkten 76 är nagot hogre an innerluftens efterstravade sluttillstand 48. Vexlingen av fuktinnehall i fuktvaxlaren 18 representeras i diagrammet for innerluftens del av entalpilinjen 58 och for ytterluftens i kretsen 20 av entalpilinjen 78, vilken senure linje slutar i punkten 80 (67°, 8 %). Den relativa fukthalten hos luften i kretsen 20 Or under vbdingsforloppet i fuktvaxlaren 18 standigt hogre men samtidigt är ocksa dess temperatur standigt hOgre. The external air in the circuit 20 has immediately been given the state of the humidity exchanger 14 in the state 60 in the diagram (89 °, approx. 3.5%) in the manner to be clarified in the following. The same moisture exchange with the inner air stream is represented by the singular arrow line 62, the moisture content being Ras to point 64 (470, 47%) which is at a higher temperature than the outer air according to point 44. It is therefore possible to cool the outer air in circuit 20 according to line 66 to point 68 (36 °, 82%) in the heat exchanger 32, the heat exchange taking place against external air passing through the duct system 40. The external air used in this case is transferred from state 44 along line 70 to state 72 (46 °, 23%). Part of the absolute moisture content in point 68 is as shown in the diagram Mgt and is therefore reduced by dilution with fresh outside air via inlet 30 and outlet 28. This dilution gives a change of condition, according to the ordinate parallel line 74 to point 76 (36 °, 72%) ,. The diagram shows that the relative moisture content at point 76 is slightly higher than the desired end state 48. The change of moisture content in the moisture exchanger 18 is represented in the diagram for the inner air part of the singular arrow line 58 and for the outer air in the circuit 20 of the singular arrow line 78, which point line ends 80 (67 °, 8%). The relative moisture content of the air in the circuit 20 Or during the ventilation process in the moisture exchanger 18 is constantly higher, but at the same time its temperature is also constantly higher.

For att na den la.ga relativa fukthalten en ligI punkten 60 i cliagrammet maste varme tillforas, vilket i diagrammet representeras av den med abskissan parallella linjen 82 och vilket sker medelst varmebatteriet 24. Luften i kretsen 20 Or dammed i stand att absorbera fukt Fran innerluften s. att den senare nar tillstandet 52. I diagrammet anger slutligen punkten 84 (470, 21 %) det till-stand, den kretsen 22 passerande ytterluftstrommen nar frail utgangslaget 44, (la den i varmevaxlaren 16 kyler innerluften enligt linjen 54. In order to reach the low relative moisture content equal to point 60 in the cliagram, heat must be supplied, which in the diagram is represented by the line 82 parallel to the abscissa and which takes place by means of the heating coil 24. The air in the circuit 20 is thus able to absorb moisture from the inner air. s. that the latter reaches state 52. In the diagram, finally, point 84 (470, 21%) indicates the state that the outer air stream passing the circuit 22 reaches frail the output layer 44, (let it in the heat exchanger 16 cool the inner air along line 54).

Det framgar av ovanstaende, att apparaten enligt fig. 1 arbetar endast med tillfersel av varme och salunda titan yttre tillforsel av vat-ten till flagon av luftstremmarna. Om luftmangden i rumsluftkretsen 12 är 100 % blir den i regenereringskretsen 20 frainfOrda ytterluftmangden lika mycket mindre som an-gives av forhallandet mellan linjernas 50 och 62 langd, 1 fereliggande fall alltsa c:a 50 %. For att sanka den absoluta fukthalten Iran punkten 68 till punkten 76 erfordras en inblandning av frisk ytterluft med c:a 25 % av luftmangden i regenereringskretsen. Med de i exemplet angivna lagena hos intaget 30 och uttaget 28 pa omse sidor om flakten 26 believer denna dimensioneras for c:a 60 % mangd totalt. Varmevaxlaren 16 fordrar en ytterluftmangd av 100 % och varmevaxlaren 32 en ytterluftmangd av 50 %, alltsa tillsammans 1%. ForhMlandet (C.P.) maim den i apparaten uppoffrade varmemangden och det fran innerluften borttagna varmeinnehallet är enligt diagrammet c:a 0,9. It can be seen from the above that the apparatus according to Fig. 1 operates only with the supply of heat and the saline titanium external supply of water to the flake of the air streams. If the air volume in the room air circuit 12 is 100%, the external air volume introduced into the regeneration circuit 20 becomes as much smaller as indicated by the ratio between the lengths of the lines 50 and 62, in the present case about 50%. In order to lower the absolute moisture content of Iran point 68 to point 76, a mixture of fresh outside air with about 25% of the air volume in the regeneration circuit is required. With the layers indicated in the example of the inlet 30 and the outlet 28 on opposite sides of the flap 26, this is dimensioned for about 60% of the total amount. The heat exchanger 16 requires an external air quantity of 100% and the heat exchanger 32 an external air quantity of 50%, i.e. together 1%. The ratio (C.P.) of the heat content sacrificed in the apparatus and the heat content removed from the inner air is, according to the diagram, about 0.9.

Diagrammet enligt fig. 8 tager viss verkningsgrad hos de respektive tillstandsvaxlarna med i berakningen, vilken sasorn av ovannamnda patent framgar kan vara mycket hog sasom 90 % och mera. Daremot forutsatter diagrammet att ett byte enbart av fukt eller av varme ager rum. Om samtidigt med den avsedda tillstandsandringen en viss tillstandsandring av det andra slaget intraffar bliva punkterna i diagrammet i motsvarande grad forskjutna sa att t. ex. our fuktavgivningen enligt linjen 50 ar kombinerad med varmeoverfering mellan tuftstrommarna, forskjutes punkten 52 at hoger i linj ens 54 ferlangning. I verkligheten ken en tillstandsandring av ovan beskriven art langs en entalpilinje ej komma till stand dels pa grund av att sorptionsvarmen ken skilja sig fran storleken av angans kondensationsvarme och dels pa grund av vaxlarkroppens ofrankomliga varmekapacitet. The diagram according to Fig. 8 takes into account the certain efficiency of the respective state shafts, which is shown to be very high by 90% and more. On the other hand, the diagram assumes that a change only of moisture or of hot fields takes place. If, at the same time as the intended state change, a certain state change of the second kind occurs, the points in the diagram become correspondingly offset, so that e.g. our moisture delivery according to line 50 is combined with heat transfer between the tufting drums, the point 52 is shifted higher in line 54's length. In reality, a state change of the kind described above along a singular arrow line cannot take place partly because the sorption heat can differ from the magnitude of the heat of condensation heat and partly because of the inexhaustible heat capacity of the exchanger body.

Vid nyss beskrivna utforingsform tages he la den for uppfuktningen av innerluften enligt linj en 58 erforderliga fuktmangden Iran: ytterluftkretsen 20. Vid utforingsformen enligt fig. 2 med tillhorande Mollierdiagram, fig. 9, astadkommes daremot denna uppfuktning till en del i den forsta fuktvaxlaren 14 med hj alp ,av innerluften, som alltsa.' under tva skeden av processere byter fukt med sig spiv. Da emellertid jamsides harmed fukt maste avlagsnas fran den kretsen 12 passerande innerluften ager en fuktborttagning rum i en andra fuktvaxlare 86. Innerluftens tillstandsforandring far i diagrammet i prim. cip samma forlopp som tidigare men mecl den skillnaden, att grenen 50 uppdelas i tva steg, namligen ett fersta mellan punkterna 46 och 88 (40°, 12 %), vilket motsvarar fukttransporten till innerluften sjalv fran tillstandet 56 till tillstandet 89 (22,5° 45 %). Del andra avfuktnin:gssteget, dvs. mellan punkterna 88 och 52, astaclkommes i fuktvaxlaren 86, sasom nedan narmare skall forklaras. Darefter gar innerluften genom varmevaxlaren 16 dar den kyles medelst ytterluft, som intages av flakten 38 i en krets 90. Innerluftens tillstandsandring aterspeglas av den punkterna 52 och 56 forbindande linjen 54 och ytterluftens av den punkterna 44 och 84 forbindande linjen 70. In the embodiment just described, the total amount of moisture required for the humidification of the inner air according to line 58 is taken: the outer air circuit 20. In the embodiment according to Fig. 2 with associated Mollier diagram, Fig. 9, on the other hand, this humidification is achieved in part in the first moisture exchanger 14 with hj alp, of the inner air, as so. ' during two stages of processing, moisture exchanges with it spiv. However, since moisture must be removed from the inner air passing the circuit 12, a moisture removal takes place in a second moisture exchanger 86. The change in condition of the inner air is shown in the diagram in prim. cip the same process as before but with the difference that the branch 50 is divided into two stages, namely a first between points 46 and 88 (40 °, 12%), which corresponds to the moisture transport to the inner air itself from state 56 to state 89 (22.5 45%). Part of the second dehumidification step, ie. between points 88 and 52, astaclcome in the moisture exchanger 86, as will be explained in more detail below. Thereafter, the internal air passes through the heat exchanger 16 where it is cooled by external air, which is taken up by the fluid 38 in a circuit 90. The change in state of the internal air is reflected by the line 54 connecting the points 52 and 56 and the line 70 connecting the external air by the points 44 and 84.

Innerluften fortsatter sedan genorn fuktvaxlaren 14 och nar tillstandet 89 for att slutligen passera en befuktningsanordning 91 av 4 i och for sig kant slag, i vilken utifran till-fort vatten avdunstar i innerluften. Innerluftens tillstandsandring i befuktningsanordningen 91 foljer i huvudsak en entalpilinje fran punkten 89 till punkten 48, som representerar det avsedda sluttillstandet hos innerluften. Anordningen 91 kan Liven vara av den konventionella art, vid vilken finfOrdelat vatten bringas i direkt kontakt med luftstrommen. The inner air then continues through the humidity exchanger 14 and reaches the state 89 to finally pass a humidifying device 91 of 4 per se edge strokes, in which from the outside water evaporates into the inner air. The change in state of the indoor air in the humidifier 91 essentially follows a singular arrow line from point 89 to point 48, which represents the intended final state of the inner air. The device 91 may be of the conventional kind, in which finely divided water is brought into direct contact with the air stream.

I kretsen 90 ãr bakom varmevaxlaren 16 a.nbragt ett ventilorgan 92, genom vilket en reglerbar del av ytterluften avgar till atmosfaren genom ett uttag 93. Denna del kan at-Ora c:a halften av den flakten 38 i kretsen intagna ytterlultmangden. Resten av ytterluften passerar i tar och ordning en varmevaxlare 94, ett varmebatteri 95, fuktvaxlaren 86 och slutligen anyo varmevaxlaren 94. Detta forlopp aterspeglas i diagrammet av en varmeupptagning fran punkten 84 till punk-ten 96 (700, 7 %), vilken sker i Yarm.evaxlaren 94,. Varmehatteriet 95 Okar temperaturen hos ytterluften ytterligare till punkten 97 (89°, 3,5 %). Ytterluften har nu lagre relativ fukthalt an innerluften av tillstandet 52 och kaa darfor regenerera fuktvaxlaren 86, varunder tillstandsandringen foljer en entalpilinje till punkten. 98 (72°, %). Denna tillstandsandring korresponderar salunda mot innerluftens tillstandsandring mellan punkterna 88 och 52. Det overskott av var.- meinnehall, som ytterluften har enligt punk-ten 98, overfores slut ligen i varmevaxlaren 94 till ytterluften av tillstandet 81, varunder ytterluften nar sluttillstandet 99 (40°, 28 %), C.P. ãr i detta fall sa lagt som c:a 0,5. Arranged in the circuit 90 behind the heat exchanger 16 is a valve member 92, through which a controllable part of the outer air is emitted to the atmosphere through a outlet 93. This part can accommodate about half of the outer volume of the air 38 taken in the circuit. The rest of the outside air passes in turn a heat exchanger 94, a heat coil 95, the moisture exchanger 86 and finally the heat exchanger 94. This process is reflected in the diagram by a heat absorption from point 84 to point 96 (700, 7%), which takes place in Yarm.evaxlaren 94 ,. The heating coil 95 Increases the temperature of the outside air further to point 97 (89 °, 3.5%). The outer air now has a lower relative moisture content to the inner air of state 52 and can therefore regenerate the moisture exchanger 86, during which the state change follows a singular arrow line to the point. 98 (72 °,%). This change of state thus corresponds to the change of state of the indoor air between points 88 and 52. The excess heat content of the outer air according to point 98 is finally transferred in the heat exchanger 94 to the outer air of the state 81, during which the outer air reaches the final state 99 (40 ° , 28%), CP is in this case as laid as about 0.5.

Utforingsformen enligt fig. 3 med tillhorande Mollier-diagram enligt fig. 10 ãr sa tillvida overensstammande med den enligt fig. 1, alt innerluften. gen.ourgar i namad ordning fuktvaxlaren 14, varmevaxlaren 16 och fuktvd.xlaren 18 i kretsen 12, irrnan den Mires tillbaka till rummet. Vidare matas varnaevaxlaren 16 direkt med ytterluft genom kretsen 22 fran flakten 38. En regenereringsluftstrom passerar en krets 100, vilken matas med ytterluft fran den for hada kretsarna gemensamma flakten 38 via ett ventilorgan 102. The embodiment according to Fig. 3 with the associated Mollier diagram according to Fig. 10 is in this respect corresponding to that according to Fig. 1, or the inner air. gen.ourgar in namad order the moisture exchanger 14, the heat exchanger 16 and the moisture tv exchanger 18 in the circuit 12, irrnan the Mires back to the room. Furthermore, the warning exchanger 16 is fed directly with external air through the circuit 22 from the baffle 38. A regeneration air stream passes a circuit 100, which is fed with external air from the baffle 38 common to the had circuits via a valve means 102.

Efter varmebatteriet 95 har ytterluften natt tillstandet enligt punkten 97 (89°, c:a 3,5 %). After the heating coil 95, the outside air at night has the state according to point 97 (89 °, approx. 3.5%).

I fuktvaxlaren 14 ager en fuktvaxling rum, varvid innerluften avfuktas frail punkten 46 till punkten 52 och ytterluften absorberar fukt frail punkten. 97 till punkten 104 (47°, 47 %). Eftersom ytterluften i punkten 104 ftr varmare an atmosfarsluften, far den i en varmevaxlare 106 avgiva varme till den i kretsen 100 just inkommande ytterluften. Harunder intraffar i forma fallet en tempera- tur-sankning fran punkten 104 till punkten 108 (38,0, 72 %) och i senare fallet en temperaturhojning fran punkten 44 till punk-ten 110 (43,0, 26 %). Vid intr5.det i fukt- vaxlaren 18 liar regenereringskretsen tillstandet 108 och avgiver fuktighet langs en- talpilinjen 112 till punkten 114 (71,5°, 9, som i fuktvaxlaren upptages av innerluften, som da uppfuktas fran punkten 56 till sluttillstandet 48. Etter fuktvax.laren 14 har ytterluften i kretsen 100 en avsevart hogre temperatur an den intagna ytterluften sedan den passerat varmevaxlaren 106 och natt tillstandet 110. Man later darfor den ytterluft, som befinner sig i den mot varnaebatteriet 95 strommande ytterluften, upptaga vfirme fran den fran fuktvaxlaren 18 avgaende ytterluften i en varmevaxlare 116,. Detta iterspeglas i Mollier-diagrammet av tillstandsandringen fran punkten 110 till punkten 118 (69°, 8 %) for den forma grenen och tillstandsandringen fran punkten 114 till punkten 120 (460, 28 %) for den andra grenen. Varmebatteriet 95 svarar f Or temperaturokningen mellan punkterna 118 och 97. In the moisture exchanger 14 a moisture exchange space acts, whereby the inner air is dehumidified from the point 46 to the point 52 and the outer air absorbs moisture from the point. 97 to paragraph 104 (47 °, 47%). Since the outer air at point 104 is warmer than the atmospheric air, it receives heat in a heat exchanger 106 to the outer air just entering the circuit 100. In this case, a temperature drop from point 104 to point 108 (38.0, 72%) occurs, and in the latter case a temperature rise from point 44 to point 110 (43.0, 26%). Upon entry into the moisture exchanger 18, the regeneration circuit reads state 108 and releases moisture along the singular arrow line 112 to point 114 (71.5 °, 9, which in the moisture exchanger is absorbed by the inner air, which is then humidified from point 56 to the final state 48. After The humidifier 14 has the outside air in the circuit 100 a considerably higher temperature than the intake outside air since it has passed the heat exchanger 106 and the night state 110. The outside air, which is in the outside air flowing towards the warning battery 95, is therefore allowed to absorb heat from it from the humidifier. This is reflected in the Mollier diagram by the change of state from point 110 to point 118 (69 °, 8%) for the shaped branch and the change of state from point 114 to point 120 (460, 28%) for the The heating coil 95 corresponds to the temperature rise between points 118 and 97.

Wrest luftmangden i innerluftkretsen 12 är 100 % blir den i kretsen 100 c:a 50 % och i kretsen 22 100 %. Flakten 38 skall alltsa totalt leverera c:a 50 % mar luft an innerluftflakten 10. C.P. blir i detta fall ungefor 0,9. Wrest the air volume in the inner air circuit 12 is 100%, it will be in the circuit 100 about 50% and in the circuit 22 100%. The vane 38 must thus deliver a total of about 50% more air to the indoor air vane 10. C.P. becomes in this case about 0.9.

UtfOringsformen enligt fig. 4 med tillhorande Mallier-diagram, fig. 11, skiljer sig fran de f8regaende hi. a. ddrigervom aft apparaten arbetar helt utan varmetillfOrsel. Till den innerluftkrets 12, som borjar och slutar i lokalen, ãr parallellkopplat ett kanalsystem 122, genom vilket en visa luttmangd aterinfores i apparaten istallet for alt avga till lokalen och vilket salunda tillsammans med ett parti av innerluftkretsen bildar en sluten bana. Denna luftmangd ãr storre an den. till lokalen atergaende luftmangden och antages vid exemplet vara dubbelt sa stor som denna. Den genom. ledningen 124 inkommande innerluften blanclas i ett ventilorgan 126 med hjalpluft fran. kanalsystemet 122, varpa blandningsluften passerar fuktvaxlaren 14. I Mollier-diagrammet aterspeglas derma blandning av att innerluft enligt punkten 46 och hjalpluft av tillstandet 128 (22,5°, 60 %) giver tillstandet 130 (24°, 56 %). Blandningsluften kan i fuktvaxlaren 14 direkt avfuktas med ytterluft, sorn intages av flakten 38 och fOres genom en. krets 132 tillbaka till atmosfaren. Denna luft har liksom Haut utgangstillstandet 44 och foljer en entalpilinje till punkten 134 (31,5°, 54 %) medan blandningsluften avfuktas till punkten 136 (27°, 41 %). The embodiment according to Fig. 4 with the associated Mallier diagram, Fig. 11, differs from the previous hi. a. ddrigervom aft the appliance works completely without heat supply. To the inner air circuit 12, which starts and ends in the room, a duct system 122 is connected in parallel, through which a certain amount of slope is re-introduced into the apparatus instead of exiting the room and which thus together with a portion of the inner air circuit forms a closed path. This amount of air is greater than that. to the room returning the amount of air and is assumed in the example to be twice as large as this. It through. the line 124 incoming the inner air is blanched in a valve member 126 with auxiliary air from. duct system 122, warp the mixing air passes the moisture exchanger 14. The Mollier diagram reflects this mixture of the fact that inner air according to point 46 and auxiliary air of state 128 (22.5 °, 60%) give state 130 (24 °, 56%). The mixing air in the moisture exchanger 14 can be directly dehumidified with external air, which is taken up by the moisture 38 and passed through a. circuit 132 back to the atmosphere. This air, like Haut, has an initial state of 44 and follows a singular arrow line to point 134 (31.5 °, 54%) while the mixed air is dehumidified to point 136 (27 °, 41%).

Blandningsluften kyles i tva steg i varmevaxlarna 138 och 140 och dess tillstandsandringar folja linjen 143 till punkten 142 (23°, 52 %) resp. linjen 144 till punkten2 48, vii-ken senare liksom tidigare är det efterstravade sluttillstandet. The mixed air is cooled in two steps in the heat exchangers 138 and 140 and its state changes follow line 143 to point 142 (23 °, 52%) respectively. line 144 to point 288, which later as before is the desired end state.

Varmevaxlaren 138 passeras av ytterluft, som intages .av flakten 38 och Over fordelarorganet 102 fOljer en krets 145. Fore intradet i varmevaxlaren 138 har ytterluften fran tillstandet 44 kylts i en varmevaidare 146 langs linjen 148 till punkten 150 (27°, 62 %) och darefter i en befuktningsanorcbling 152 genom avduristning av vatten erfarit en tillstandsandring langs entalpilinj en 154 till punkten 156 (22°, 95 %). Varmeupptagningen hos denna ytterluftstrom svarar mot linjen 158 till punkten 160 (26°, 75 %), -vilken linje korresponderar med den punkterna 136 och 142 forbindande linjen 143. I varmevaxiaren 146 byter ytterluftstrommen varme med sig sjalv, sa att dess avgaende gren liar sluttillstandet 162 (34°, 48 %), varvid den punkterna 160 och 162 forbindande linjen 164 korresponderar med linjen 148. Ytterluftstrommen. avgar salunda till atmosfaren under tillstandet 162. The heat exchanger 138 is passed by external air, which is taken in by the flange 38 and Above the distributor means 102 follows a circuit 145. Before entering the heat exchanger 138, the external air from state 44 has been cooled in a heat exchanger 146 along line 148 to point 150 (27 °, 62%) and then in a humidification anorcling 152 by de-roasting water experienced a state change along the singular arrow line 154 to point 156 (22 °, 95%). The heat absorption of this outer air stream corresponds to line 158 to point 160 (26 °, 75%), which line corresponds to the line 143 connecting points 136 and 142. In heat exchanger 146, the outer air stream exchanges heat with itself, so that its outgoing branch reaches the final state. 162 (34 °, 48%), the line 164 connecting the points 160 and 162 corresponding to the line 148. The outer air stream. emits salunda to the atmosphere during state 162.

Den for avkylningen av blandningsluften erforderliga temperaturskillnaden astadkommes med hj alp av en befuktningsanordning 166, soni är insatt i kanalsystemet 122 och vilken liksom anordningen 152 är av gamma art som anordningen 91. Sedan blandningsInnen lamnat varmevaxlaren 140 har den sasom ovan namnts sluttillstandet 48. I befuktningsanordningen 166 .sker nu en avdunstning av vatten, st att den. i kanalsystemet atergaende hjalpluften kyles langs entalpilinjen 168 till punkten 170 (15,5°, 94 %), varigenom hjalpluften salunda bringas i ett tillstand, dar den kan upptaga varme langs linjen 172 till det forut namnda tillstandet 128. Den punkterna 142 och 48 fOrbindande linjen 144 och linjen 172 angiva tillstandsandringen hos de hada luftstrommarna i varmevaxlaren 140. Linjen 172 har stone langd an linjen 144, vilket sammanhanger med att hjalpluftmangden i kanalsystemet 122 endast ãr tva tredjedelar av den varmevaxlaren passerande blandningsluftmangden. Den till lokalen atergaende regenererade luftmangden fir givetvis lika stor som den frail lokalen genom ledningen 124 i apparaten intagna. Av diagrammet framgar, att de ytterluftstrOmmar, som passera fuktvaxlaren 14 resp. varmevaxlaren 138, aro lika stora som den samma vaxlare passerande blandningsluftmangden. G.P. är lika med 0, eftersom varme ej behover tillforas. The temperature difference required for cooling the mixing air is achieved by means of a humidifier 166, which is inserted in the duct system 122 and which, like the device 152, is of the same type as the device 91. After the mixture has left the heat exchanger 140, it has the final condition 48. 166 .there is now an evaporation of water, st that it. the auxiliary air returning in the duct system is cooled along the singular arrow line 168 to the point 170 (15.5 °, 94%), whereby the auxiliary air is thus brought into a state where it can absorb heat along the line 172 to the aforementioned condition 128. The points 142 and 48 connecting line 144 and line 172 indicate the state change of the hot air streams in the heat exchanger 140. Line 172 is stone length longer than line 144, which is due to the fact that the auxiliary air quantity in the duct system 122 is only two thirds of the heat air flow passing the mixing air quantity. The amount of air regenerated returning to the room is of course as large as the frail room taken in through the line 124 in the apparatus. The diagram shows that the external air streams which pass the moisture exchanger 14 resp. the heat exchanger 138, are as large as the same exchanger passing the mixing air volume. G.P. is equal to 0, since heat does not need to be supplied.

Utforingsformen enligt fig. 5 med tillho rande Mollier-diagram enligt fig. 12 har liksom den, foregaende en hjalpluftkrets pa innerluftsidan, som cirkulerar i en sluten balm jamsides med cirkulationen av innerluft frau och till lokalen. Hjalpluftmangden Or emellertid i detta fall stone, vid exemplet fyra ganger sa. stor som innerluftmangden mot tva ganger forut. Avsikten harmed ar att kunna forskjuta punkten 142 sa langt at la5- ger i diagrammet, att varmevaxlaren 146 kan undvaras. En st8rre del ,av blandningsluftens kylning kommer salunda pa varmevaxlaren 140 jamfort med den foregaende utforingsformen. Detta for alltsa med sig, att kylningen av varmevaxlaren 138 kan ordnas med enklare medel. The embodiment according to Fig. 5 with the associated Mollier diagram according to Fig. 12 has, like the previous one, an auxiliary air circuit on the inner air side, which circulates in a closed balm alongside the circulation of inner air from and to the room. The auxiliary air quantity Or, however, in this case stone, at the example four times said. large as the amount of indoor air compared to twice before. The intention is to be able to shift point 142 so far that it is in the diagram that the heat exchanger 146 can be dispensed with. A larger part, of the cooling of the mixing air, thus comes on the heat exchanger 140 compared to the preceding embodiment. This means that the cooling of the heat exchanger 138 can be arranged by simpler means.

Ytterluften av tillstandet 44 intages i kretsen 175 och passerar forst fuktvaxlaren 14, varvid den nar tillstandet 177 (32°, 53 %) i diagrammet. Samma luft bringas emellertid vid utforingsformen enligt fig. 5 att passera befuktningsanordningen 152, varvid tillstandsandringen hos ytterluften fOljer en entalpilinj e till punkten 176 (24°, 96 %). En varmevaxling i varmevaxlaren 140 Iran punk-ten 176 till punkten 178 (26,5°, 83 %) p ytterluftsklan och Iran punkten 179 (27°, 41 %) till punkten 181 (24,5°, 48 %) pa blandningsluftsidan kan darmed genomforas. Friskluftflakten 38 har i delta fall en kapacitet motsvarande fern ganger den mellan lokalen och apparaten cirkulerande innerluftmangden. The outside air of state 44 is taken up in circuit 175 and first passes the moisture exchanger 14, reaching state 177 (32 °, 53%) in the diagram. However, in the embodiment of Fig. 5, the same air is caused to pass the humidifier 152, the change of state of the outside air following a singular arrow line to point 176 (24 °, 96%). A heat exchange in the heat exchanger 140 Iran point 176 to point 178 (26.5 °, 83%) on the outer air clan and Iran point 179 (27 °, 41%) to point 181 (24.5 °, 48%) on the mixed air side can thus implemented. In some cases, the fresh air flat 38 has a capacity corresponding to four times the amount of indoor air circulating between the room and the apparatus.

Pa hmerluftsidan nar hjalpluften efter uppfuktningsanordningen 166 tillstandet 183 (15,5°, 97 %) ()eh efter varmevaxlaren_ 140 tillstandet 185 (23,°, 59 %). Blandningsluftens tillstand fore flakten representeras av punkten 187 (24°, 57 %). On the hot air side, the auxiliary air after the humidifier 166 reaches the state 183 (15.5 °, 97%) () eh after the heat exchanger_ 140 the state 185 (23, °, 59%). The state of the mixing air before the surface is represented by the point 187 (24 °, 57%).

Den apparaten vid utforingsformen enligt fig. 5 lamnande ytterluften har tillstandet 178 och alltsa betydligt lagre temperatur ani ytterluftens enligt punkt 44. For att nyttiggora denna ternperaturskillnad har vid utfOringsformen enligt fig. 6 med tillhorande Monier-diagram enligt fig. 13 insatts en varmevaxlare 180, som 5. ena sidan passeras av den frail fuktvaxlaren 14 och a andra sidan av den frail varmevaxlaren 138 kommande grenen i ytterluftkretsen 175. Forloppet i innerluf tkretsen med dess hjalpluftkrets Or dens am-ma som forut, bortsett frail att proportionen mellan cirkulerande innerluft och hjalpluft Or 1: 3, med darav betingade smarre andringar i de olika stationemas tillstand. Liksom vid utforingsformen enligt fig. 4 och 5 torkas blandningsluften i fuktvaxlaren 14 till absoluta fuktnivan hos punkten 48, medan relativa fukthalten efter torkningen ej underskrider atmosfarsluftens. 6 Ytterluften kyles efter punkten 189 (32°, 51 %), da den salunda uttratt ur fuktvaxlaren 14, till punkten 182 (27°, 67 %) i varmevaxlaren, 180. Efter uppfuktning i befuktningsanordningen. 152 langs en entalpilinje frail punkten 182 till punkten. 184 (24°, 90 %) sker varmeupptagningen i varmevaxlaren 138 till punkten 186 (26,5°, 76 %). Fran punkten 186 sker varmeupptagning i varmevaxlaren 180 till ytterluftens sluttillstand 188 (31,5°, 58 %). I varmevaxlaren 180 har alltsa den en,a grenen i ytterluftkretsen avgivit varme mellan punkterna 189 och 182, vilken upptagits av den andra grenen mellan punk: terna 186 och 188. Punkten 188 ligger ph hog-re temperatur an punkten 178 enligt foregaende utforingsform. The apparatus in the embodiment according to Fig. 5 which leaves the outside air has the condition 178 and thus a significantly lower temperature than the outside air according to point 44. In order to make use of this temperature difference, a heat exchanger 180 has been used in the embodiment according to Fig. 6 with associated Monier diagram according to Fig. 13. which 5. on one side is passed by the branch of the frail moisture exchanger 14 and on the other side of the frail heat exchanger 138 coming branch in the outer air circuit 175. The course in the inner air circuit with its auxiliary air circuit Or its breast as before, except frail that the ratio between circulating inner air and auxiliary air Or 1: 3, with the consequent slight changes in the condition of the various stations. As with the embodiment of Figs. 4 and 5, the mixing air in the moisture exchanger 14 is dried to the absolute moisture level at point 48, while the relative moisture content after drying does not fall below that of the atmospheric air. 6 The outside air is cooled after point 189 (32 °, 51%), as it has thus escaped from the humidity exchanger 14, to point 182 (27 °, 67%) in the heat exchanger, 180. After humidification in the humidifier. 152 along a singular arrow frail point 182 to the point. 184 (24 °, 90%) the heat is absorbed in the heat exchanger 138 to point 186 (26.5 °, 76%). From point 186, heat is taken up in the heat exchanger 180 to the final state of the outside air 188 (31.5 °, 58%). In the heat exchanger 180, therefore, one of the branches in the outer air circuit has given off heat between points 189 and 182, which are occupied by the other branch between points 186 and 188. Point 188 is higher than point 178 according to the preceding embodiment.

Utforingsformen enligt fig. 7 med tillhorande 1VIollier-diagram fig. 14 skiljer sig fran de enligt fig. 4-6 sâ tillvida, att regenereringsluften na.got uppvarmes for nedbringan.- de av de apparaten passerande luftmangderna. I ytterluftkretsen 175 har salunda insatts ett varmebatteri 190 framfor fuktvaxlaren 14. Enligt fig. 14 bringas darmed ytterluften av tillstandet 44 till tillstandet 192 (39°, 32 %). Lokalluften, som liksom tidigare har tillstandet 46, blandas fore intradet i fuktvd.xlaren 14 med fra.n kanalsystemet 122 kommande hjalpluft av tillstandet 194 (24,5°, 64 %) och blandningsluften far tillstandet 196 (25,7°, 57 %). I delta fall är hjdlpluftens andel i blandningsluften mindre; vid exemplet antages forhallandet vara 1: 1. I fuktvaxlaren nedbrings blandningsluftens fuktinnehall till punkten 198 (31°, 33 %) medan samtidigt ytterluftens av tillstandet 192 Okas till punk-ten 298 (32,5°, 55 %). The embodiment according to Fig. 7 with the associated 1VIollier diagram Fig. 14 differs from those according to Figs. 4-6 in that the regeneration air is slightly heated to reduce the air volumes passing through the apparatus. In the outer air circuit 175, a heating coil 190 has thus been inserted in front of the moisture exchanger 14. According to Fig. 14, the outer air is thus brought from the state 44 to the state 192 (39 °, 32%). The local air, which as before has the state 46, is mixed before entering the humidifier 14 with auxiliary air coming from the duct system 122 of the state 194 (24.5 °, 64%) and the mixing air reaches the state 196 (25.7 °, 57% ). In some cases, the proportion of the auxiliary air in the mixing air is smaller; in the example, the ratio is assumed to be 1: 1. In the humidity exchanger, the moisture content of the mixing air is reduced to point 198 (31 °, 33%) while at the same time the external air of the state 192 Okas is reduced to point 298 (32.5 °, 55%).

I kretsen 199 bringas en annan ytterluftstrom medelst befuktningsanordningen 152 frau tillstandet 44 till tillstandet 200 (24,5°, 95 %).. Derma grenstrom passerar sedan varmevaxlaren 138, som kyler blandningsluften pa innerluftsidan till tillstandet 202, (25°, 47 %), varvid den sjalv bortgar med tillstandet 204 (30,5°, 65 %). I en fordelningsventil 206 delas nu blandningsluften i tva strommar, av vilka en gar in i kanalsystemet 122 och da forst passerar befuktningsanordningen 166, som kyler luften till tillstandet 208 (17,5°, 95 %). I varmeva.xlaren 140 upptager hjalpluften i kanalsystemet 122 varme till punkten 194, vilken varme bringar den till lokalen atergaende innerluften Iran tillstandet 202 till sluttillstandet 48. I detta fall Or som ovan namnts den till lokalen ater*ride luftmangden och den genom kanalsystemet 122 till flakten 10 aterfOrda luf tmangden. lika stora. G.P. blir 0,5 4 0,6. In circuit 199, another external air stream is brought by the humidifier 152 from state 44 to state 200 (24.5 °, 95%). This branch current then passes the heat exchanger 138, which cools the mixed air on the inner air side to state 202, (25 °, 47%). , leaving itself with the state 204 (30.5 °, 65%). In a distribution valve 206, the mixing air is now divided into two streams, one of which enters the duct system 122 and then first passes the humidifier 166, which cools the air to the state 208 (17.5 °, 95%). In the heat exchanger 140, the auxiliary air in the duct system 122 absorbs heat to the point 194, which heat brings the internal air returning to the room Iran state 202 to the final state 48. In this case Or as mentioned above it returns the air volume to the room and flakten 10 aterfOrda luf tmangden. as big. G.P. becomes 0.5 4 0.6.

Uppfinningen är givetvis icke begransad till ovan beskrivna utforingsformer utan kan varieras i vidstracktaste bemarkelse Mom rumen av den till grund for densamma liggande idea sadan denna exempelvis belyses av de efterfOljande anspraken. Salunda kunna delar i de olika utf5ringsformerna kombineras med varandra pa. vale tankbart salt. The invention is of course not limited to the embodiments described above, but can be varied in the broadest sense of the scope of the idea underlying it, so that this is illustrated, for example, by the following claims. Thus, parts of the various embodiments can be combined with each other on. vale tankbart salt.

4. A claim according to claim 1, characterized in that the drying of the air stream to be conditioned takes place partly by the exchange of moisture in the air stream with itself. then, suitably in immediate succession, in the moisture exchanger (86, Fig. 2).

5. A kit according to claim 1, Urinated in that the air stream to be conditioned is guided, as it has a high absolute and relative moisture content, through the moisture exchanger (14, Fig. 2), which absorbs moisture in the air stream, whereby it is heated and its absolute as well as relative moisture content falls, while the air stream after cooling is brought into contact with the same moisture exchangers, whereby an evaporation from this of the occupied water takes place, so that the temperature. in the air stream decreases and its absolute and relative moisture content rises.

6. A kit according to claim 1, characterized in that the air stream to be conditioned is dried and cooled a second time during moisture exchange with a separate second air stream, the latter of which rearranges a cooling stage and a drying stage, the former air stream during its drying stage the higher heat content, while the second air stream under the silt cooling stage liar the higher heat content (fig. 1 on 3).

7. Salt according to claims 1 and 7, characterized in that during the drying step the moisture absorbed by the moisture exchanger is expelled from it in vapor at a higher temperature and a higher vapor pressure and that the kiwi is then brought into liquid form by sorption and evaporated to cool. the fragrance stream to be conditioned (Figs. 1 and 3).

Ended patent claim 8, characterized in that the expulsion of the moisture during the drying step takes place by means of the second air stream, which then has a higher temperature and higher pressure than the first-mentioned air stream, and that the second air stream is brought after cooling and dilution with air of lower pressure. in turn cooling the first air stream during the release of moisture to it (Figs. 1 and 3). A device for carrying out the set according to any one of the preceding patent claims, comprising a conduit system (12; 124, 12), between which and the space an air stream is circulated and to which is connected partly a regenerative moisture exchanger (14, fig. 1, 3-7; 86, Fig. 2), which is alternately brought into contact with the air stream for its drying flake and with regeneration air for the regeneration of the moisture exchanger, saint a cooling element (16, Figs. 1-3, 138, Figs. 4-7) for removal of sensitive heat from the air stream by heat exchange with a colder medium, can be drawn by an element (18, Figs. 1 and 3; 14 Fig. 2; 140, Figs. 4-7), connected to the pipe system and arranged for further cooling of the dried the air strain by exchange with other air.
