Definitions
- the invention relates to a method for carrying out an alternating evaporation and condensation process of a working medium according to the preamble of claim 1 and to an apparatus for operating such a method according to the preamble of claim 5.
- Such devices are used for example in air conditioning, especially in thermal adsorption heat pumps or refrigeration systems.
- a working medium in the form of a refrigerant medium is cyclically adsorbed and desorbed. It is transferred from the gas phase in the liquid state or from the liquid state back into the gas phase. The resulting heat of condensation is dissipated to the outside or must be supplied to the device from the outside.
- condensation and evaporation are similar in terms of heat technology, they require different conditions for achieving good heat transfer. These are largely determined by the transport of heat through the film of the working medium. The thicker the film, the greater the heat transfer resistances must be overcome.
- the film which forms is removed from the heat transfer surface by suitable measures, in particular surface coatings or surface structures.
- suitable measures in particular surface coatings or surface structures.
- evaporation on the other hand, an attempt is made to produce as thin a film as possible on the heat transfer surface.
- Such devices are therefore designed, for example, as a falling film evaporator or rotary evaporator, in which the working medium is distributed as thin as possible.
- the device should be used in particular in cyclic processes in which the working medium is vaporized and condensed in one and the same apparatus and ensures the highest possible effectiveness in both process phases.
- the object is achieved with a method for carrying out an alternating evaporation and condensation process of a working medium having the characterizing features of claim 1.
- the subclaims contain expedient and / or advantageous embodiments of the method according to the invention.
- the object is achieved by a device having the characterizing features of claim 5.
- the subclaims also contain expedient and / or advantageous embodiments of the device.
- the method for carrying out an alternating evaporation and condensation process of a working medium on a heat transfer surface which is simultaneously provided as evaporation and condensation surface is characterized in that a condensate film of the working medium forming during the condensation process becomes permanent during one working cycle of one condensation process and one evaporation process remains on the heat transfer surface and is then evaporated from the heat transfer surface during the evaporation process.
- the basic idea of the method according to the invention is thus to leave the condensate film of the working medium forming during the condensation on the heat transfer surface and to store it there temporarily. During evaporation, this condensate film is returned to the gas phase. This achieves two effects.
- the heat transfer in the condensation takes place only until the entire condensate film has formed. At this point, the working fluid is completely condensed and the condensation is completed. The heat transfer from the working medium to the heat transfer surface is thereby affected only to a small extent, because during the condensation of the film has not yet fully formed.
- the thin and uniform distribution of the liquid working medium advantageous for the evaporation process is effected as it were and does not have to be generated by additional devices or process steps. In sum, both the condensation process and the evaporation process are thus carried out with the same effectiveness on one and the same heat transfer surface and can take place without intermediate steps.
- the ratio between the amount of the working fluid and the size of the heat transfer surface is set at least such that the thickness of the condensate film remains below a critical film thickness at which dripping of the condensate film begins.
- the entire working fluid is condensed and stored in situ on the heat transfer surface. Storage steps and later distribution steps are no longer necessary. Also eliminates collection facilities for the condensate.
- the heat transfer surface itself acts as a storage location.
- the ratio between the amount of the working fluid and the size of the heat transfer surface is adjusted to achieve substantially homogeneous coverage of the heat transfer surface with a minimum thickness of the condensate film.
- a design ensures the highest possible efficiency of the evaporation process and at the same time maximum utilization of the heat transfer surface as in situ storage for the condensate.
- the coverage of the heat transfer surface with the condensate film is achieved by a hygroscopic / spreading and / or devisvidveriesrnde formation of the heat transfer surface. As a result, the condensate film spreads uniformly, and the increase in surface area of the heat transfer surface increases its storage capacity.
- an apparatus for carrying out an alternating evaporation and condensation process of a working medium on a heat transfer surface simultaneously provided as evaporation and condensation surface is characterized in that the heat transfer surface as an in situ storage for a remaining on the heat transfer surface during the condensation process and during the evaporation process evaporating, the heat transfer surface covering and not dripping condensate film of the working medium is formed.
- the ratio between the size of the heat transfer surface and the amount of working fluid transferred into the condensate film is such that the thickness of the condensate film is minimal with substantially homogeneous coverage of the heat transfer surface. This in particular increases the efficiency of the evaporation process.
- the heat transfer surface has a surface modification in the form of a hygroscopic and / or the working medium spreading surface coating on the working medium. This achieves a homogeneous and uniform condensate film.
- the heat transfer surface has a surface-enlarging formation. This increases the storage capacity of the heat transfer surface.
- the surface-enlarging formation is formed in an expedient embodiment in the form of a porous and / or fibrous structure.
- Fig. La example tube for a heat transfer medium with a porous sheath
- FIG 3 shows an exemplary time profile of the film thickness of the condensed working medium during a work cycle as a function of time.
- Fig. 1 shows a basic structure of the device according to the invention.
- the device comprises a container wall 1 shown schematically here, which encloses a volume through which the working medium flows. Inside the container wall is a multiply divided heat transfer surface 2, which is arranged on a snake-like laid pipe 2a.
- the pipe 2a is traversed by a heat transfer medium, which dissipates the heat of condensation of the working medium or the working medium supplies the required heat of evaporation.
- the heat transfer surface is formed here as a whole of individual lamellae.
- the fins are oriented so that they can be acted upon by the working medium as effectively as possible. They form the largest possible surface.
- the heat transfer surface ie the lamellae used here, each have a surface modification 3.
- the surface modification is formed in various ways. However, it is clear that in the concretely realized embodiment of the device only a respectively preferred and uniform design of the surface modification can be present.
- the surface modification in the example shown here consists of a spreading hydrophilic surface coating 4 and a series of porous fillers or a porous cover 5 which are applied to the heat transfer surface 2, ie the individual lamellae.
- both the hydrophilic coating or the porous cover can be provided alone or in combination.
- the filler or the porous cover can be impregnated with the material of the surface coating 4 or coated at least superficially.
- the porous cover has a good thermal conductivity.
- the hydrophilic surface coating 4 is formed so that the precipitating thereon, i. Run through condensing droplets of the working medium to a closed film, which covers the entire heat transfer surface and remains there permanently even after the completion of the condensation process.
- hydrophilic materials which on the one hand are temperature-resistant and on the other hand ensure the smallest possible, ideally a vanishing contact angle for accumulated condensate droplets.
- the porous packing ensures an enlarged inner surface of the device.
- these bodies act as a sponge and act as a condensate reservoir for the entire amount of condensed and vaporized working medium.
- the shape of the heat transfer surface is further designed so that sharp corners and edges are avoided, which can lead to the tearing of the liquid film and dripping of the film.
- Fig. La shows an exemplary pipe 2a, in which the pipe wall itself is formed as a porous cover. However, this is tight to the pipe internal volume, so that no mass transfer between the inside and outside, but only a heat transfer takes place.
- a tube can be made by sintering granules on a thin-walled starting tube or by another coating method. Of course, a hydrophilic coating may additionally be present.
- the loading of the device with the working medium is indicated in the illustration in Fig. 1 by block arrows and lateral inlets and outlets 5a.
- the gaseous working medium enters the device and settles on the heat transfer surface.
- the working medium gives off condensation heat to the heat transfer surface.
- the entire working medium is deposited on the heat transfer surface as a thin as homogeneous as possible condensate film. Its thickness is adjusted by the amount of the working medium and by the size of the heat transfer surface regardless of the actual process process undergone process so that the condensate film does not drip and adhere by adhesion forces on the heat transfer surface.
- the condensate film is thin enough to make the heat input during evaporation as efficient as possible.
- the heat transfer surface thus forms an in situ storage for the condensed working medium. This means that the working medium is not transferred to an additional reservoir, but is stored exactly at the point where the condensation or the evaporation actually takes place.
- Fig. 2 The course of the condensation and evaporation process is shown in Fig. 2 in more detail.
- Fig. 3 shows the associated time course of the thickness of the deposited on the heat transfer surface liquid film of the working medium.
- the evaporation process is shown on the left in FIG. 2, the process of condensation is illustrated by the right-hand part of FIG. 2.
- evaporation of the working medium is supplied from the outside via the container wall 1 evaporation heat Q v in a sufficient amount. This converts at least a portion of the surface of the coating 4 located on the working medium in the vapor phase.
- the evaporation is carried out so that the working medium has been completely transferred from the heat transfer surface in the vapor phase.
- the condensation process corresponds to a reversal of the evaporation process.
- the vaporous working medium is precipitated from the gas phase at the heat transfer surface and releases there the condensation heat Q K.
- the surface film 6 forms again on the surface coating 4.
- Fig. 3 shows the associated time course of the existing on the heat transfer surface thickness of the surface film.
- the surface film grows steadily and finally reaches a maximum film thickness D max of the condensate film of the working medium.
- the thickness D max is determined essentially only by the ratio of the total volume of the working medium to the size of the available heat transfer surface.
- V ges of the working medium in the process and a heat transfer surface with the effective surface area A e ff
- the simple relationship D max ges / A e ff applies for the thickness D max .
- the condensate film is degraded again.
- the working medium returns to the gas phase, so that after a certain time, the thickness of the surface film drops to a value D 0 .
- D 0 0. In this case, the surface film has completely disappeared and the evaporation process has reached its absolute end.
- the above-explained process steps represent a running in the device boundary process having a certain control width.
- the film thickness achieved during the working cycles can thus be changed within the predetermined range between D 0 and D max .
- condensation process can be driven so that after its completion not the maximum film thickness D max , but a lower deposition thickness D K sets.
- Such process regimes make it possible either to compensate for certain fluctuations within the heat loads during thermal contact of the device with the environment or to set operating states of the thermodynamic process coupled to the device in a targeted manner.
