Definitions

  • the present invention relates to a dryer cabinet or also called drying cabinet with one drying room and one Apparatus part with a heat pump, consisting of an evaporator unit, a compressor and a condenser and with a circulating air generating organ for generating air circulation in the closet, a method of operating a drying cabinet, as well as its use for drying textiles and others Goods.
  • a heat pump consisting of an evaporator unit, a compressor and a condenser and with a circulating air generating organ for generating air circulation in the closet, a method of operating a drying cabinet, as well as its use for drying textiles and others Goods.
  • From CH-A-672 836 is a two-part clothes dryer cabinet known in which the drying of wet laundry with a closed air circuit takes place.
  • This closed air cycle has proven to be disadvantageous by that If the heat pump is operated, the air is gradually heated, which either increases the performance of the cooling unit or the heat pump is required or the efficiency the drying process with increasing duration drying operation decreases. The consequence of this is a high one Energy expenditure and overheating of the heat pump.
  • EP 0 467 188 also discloses a tumble dryer with a Open air circuit known, similar to the solution proposed in Swiss patent application CH 1275/96.
  • the difference the resulting Swiss patent application is the resulting one here Excess air already after heating by the condenser and before entering the drying cabinet again to the Given environment, which in contrast to the CH 1275/96 in the EP 0 467 188 emits warm and dry air to the environment becomes.
  • the advantage is that on the one hand the environment, such as a basement, does not get wet and also heating the quasi-closed air circuit in the drying cabinet can be avoided.
  • the disadvantage lies in the relatively small amount of air flowing through the drying room is led, which leads to an extension of the drying process can lead.
  • This additional air flow is such that part of the air circuit is in direct bypass of the evaporator and the condenser are recirculated through the apparatus part becomes.
  • the advantage of this additional air flow is that with practically the same facility a significantly increased for the generation of the air circuit Air flow generated through the dryer room or the dryer cabinet can be considered as for example in the proposed Facilities known from the prior art.
  • This increased Airflow in the dryer room leads to increased movement of the material to be dried, which speeds up the drying process considerably can be.
  • Another advantage of this solution is in the fact that only a relatively small part of the moist, warmed air is released to the environment, which is sufficient to heat the quasi-closed air circuit to avoid in the drying cabinet.
  • bypass air flow can either preferably largely as much as possible during the entire drying process can be chosen constant or variable or controllable. Especially with constant bypass airflow the significant advantage that an additional regulation and control body can be dispensed with.
  • the bypass air duct proposed according to the invention can both be formed in one and two parts by the at least partially untreated, moist and warm amount of air from the outlet from the dryer room practically until it re-enters the dryer room separate from those arranged in the appliance part Devices, such as evaporators, condensers, etc., is performed. Or the mentioned amount of air is after passing the evaporator mixed with the cooled and dried air there, whereupon the mixed air thus obtained passes through disconnected the condenser to reheat the air is carried out so that part is separated from the capacitor and the other part through the capacitor. Is essential in both cases that part of the recycled and closed Air circuit largely unhindered by the apparatus part runs through, thereby with constant performance the facility responsible for air circulation larger air volume can be promoted.
  • a heat recovery unit is arranged upstream of the evaporator, such as a so-called plate heat exchanger, in which in countercurrent or crosscurrent is part of that from the Dry and warm air and the exhausted drying cabinet cooled and dried amount of air passed through the evaporator become.
  • the plate exchanger the amount of air cooled and dry by the evaporator Part of the moist and warm exhaust air from the drying cabinet already precooled or pre-dehumidified and thus the total required Performance in the heat pump or in the cooling unit reduced can be.
  • the cooling capacity of the evaporator be reduced and on the other hand the heating output in the capacitor, since in the proposed according to the invention Heat recovery unit on the one hand part of the moist, warm exhaust air is cooled from the drying cabinet and on the other hand, the cool, dry air corresponding to the part already warmed up a bit.
  • Another big advantage in the use of this heat recovery unit is that with progressing duration of the drying operation the performance this recovery unit is increased by the temperature difference between the warm, moist exhaust air from the Dryer cabinet and the cooled, dry air increases. This results in known compared to the drying cabinet from the prior art, the further big advantage that the increasing power consumption of the heat pump during the Drying process is much less when used this heat recovery unit, such as the heat recovery plate exchanger mentioned.
  • the bottom line is a much better one Efficiency of the drying unit and associated with it Reduction of the drying time required as well as an essential lower energy requirements than those from today Drying cabinets known in the prior art.
  • FIG. 1 shows a drying cabinet 1 with a door opening 2 and locks 4.
  • a front cover or a heat pump 3 arranged, which front cover, for example can be closed by means of square closures 5.
  • this front cover is also an operating display 7 and an air inlet opening 21, on their operation to be received later.
  • an air outlet opening 36 is arranged on the way it works is also to be discussed below.
  • FIG. 2 now shows that arranged above the dryer room 1 Heat pump or apparatus part 3 with the front cover removed, so that the individual components of the heat pump are visible are.
  • the actual heat pump consists of a heat recovery unit, such as a plate exchanger 14, an evaporator 15, a condenser 25 and a compressor 27. Via connecting lines 28, 29 and 31 are the ones that make up the actual heat pump Units for the transport of the cooling medium connected to each other.
  • a fan is provided for generating the air circulation 35, and for generating what is proposed according to the invention
  • Bypass airflow 18 resp. 32 is an air passage on the one hand 12 and a further air passage 30 are provided.
  • the air 16 cooled and dehumidified in this way is recirculated and across the warm and humid exhaust air flow 11 again led the plate exchanger 14 to be heated itself, and on the other hand to pre-cool the warm and humid exhaust air or pre-dehumidify.
  • Another part of the moist and warm exhaust air 11 is untreated passed through the air passage 12 to form a first bypass air flow 18, which with the again through the Plate exchanger guided and heated air 16 is mixed.
  • the mixed circulation air 17 thus formed becomes too high Dryer room temperature at the air inlet opening 21 with additional air 19 mixed from outside.
  • the main part 23 this mixed air is then passed through the condenser 25 led and heated.
  • the other part of this mixed air through a second air passage 30 to form the second Air bypasses 32 out.
  • This bypass air volume 32 like also the mixed air 33 heated by the condenser 25 becomes sucked by the fan 35 and after passing through the Fan through an air grille 38 as heated and relative dry air 39 supplied to the dryer room 1.
  • the humidity the air 39 supplied to the dryer room is probably possible slightly higher than the corresponding humidity for supply air in drying cabinets, known from the prior art, however, this is not a disadvantage due to the increased air flow.
  • the increased amount of air, which is passed through the dryer room, the drying efficiency in the Dryer room increased because that in the dryer room too drying goods, such as clothes, moved more intensively the air flow is at least partially turbulent is.
  • partition or partition plate 22 generated the deflection of the air flow for the second flow of Plate exchanger.
  • Figure 3 shows the heat pump or the apparatus part 3 from above seen with the cover off, so that the individual apparatus units are visible.
  • a repeat of the individual Parts of the apparatus can largely be dispensed with as one and the same parts of the apparatus with the same reference numerals are.
  • the two air openings 12 and 30 are only indicated by dashed lines because they are difficult to display from the top are.
  • Fig. 4 finally shows in section along the apparatus part the line B-B of Fig. 2, seen towards the capacitor 25.
  • the air inlet opening is clearly recognizable 21 for the supply of air from outside as well as the air passage 30 for the formation of the second bypass air flow.
  • FIGS. 2 to 4 clearly show the apparatus and simple design of the heat pump or Equipment part.
  • a Circulation-generating organ such as a single fan 35
  • the performance this fan 35 can be kept relatively low because the "closed" airflow to be recycled is partly parallel via the two bypass air ducts through the apparatus part is led through. This is also reflected in less Low electricity demand.
  • the fact that that relatively little moist warm air to the environment is released and not, as with known drying cabinets, large amounts of humid, warm air, resulting in an uncomfortable Increase in humidity in the area can result.
  • the bypass air flow can be operated with a constant amount, such as approximately 20% -30%, based on the total amount of the air flow circulating within the apparatus part 3. So it is possible, for example, with a total air flow within the apparatus part 3 of approx. 850-950 m 3 of circulating circulating air, an air flow of approx. 150-250 m 3 as a bypass air flow 18 or. 32 feed.
  • a total air flow within the apparatus part 3 of approx. 850-950 m 3 of circulating circulating air an air flow of approx. 150-250 m 3 as a bypass air flow 18 or. 32 feed.
  • the control of the air flap mentioned can be coupled, for example, to a thermostat arranged in the apparatus part, which determines the temperature of the drying air 33 heated after the condenser or of the air 39 introduced into the drying chamber. If, for example, the temperature of the air 39 introduced into the drying room exceeds a value of approximately 40-45 ° C., an increased amount of air 19 is to be supplied to the air circuit through the opening 21. In order to come back to the example mentioned above, it has been shown in practice that it makes sense, for example, to supply approximately 100-200 m 3 of air to the total amount of air flow inside the apparatus part 3, so that a total of approximately 1000 by the fan 35 - 1100 m 3 of drying air 39 is blown into the dryer room 1.
  • bypass air volume 18 or 32 it is also possible to vary the bypass air volume 18 or 32 to design, for example, again coupled with the im Apparatus part arranged thermostats.
  • FIGS. 2 and 3 the condensate discharge is not shown and are neither a hygrostat nor a thermostat shown, since their use in drying facilities, like the drying cabinet described according to the invention, ideal is known. So it is also possible, for example Apparatus part or the cooling unit on the side of the drying cabinet to attach or below the drying cabinet or on the Back of the closet.
  • the one proposed according to the invention is Dryer cabinet not restricted for drying textiles usable, but can of course be used for drying of any parts, materials, apparatus parts to be dried, Devices, tools, bulk goods and the like are used.
