Definitions
- the invention relates to an air cooling and air dehumidifying module with a heat exchanger element comprising plastic capillary tube mats which are shaped so as to form a compact packet with a virtually cuboid external shape, which cools and dehumidifies the air flow directed through the mat packet when cold water is fed through the capillary tubes.
- the invention further relates to a method of operating the air cooling and air dehumidifying module in combination with a cooling ceiling. The purpose of this type of solution is to cool a room and dehumidify the air in the room on a decentralised basis.
- Compact water/air heat exchangers are generally made from metal, in which case aluminium and copper are used by preference due to their high capacity to conduct heat. These materials are expensive, require a lot of processing work and above all produce condensate in most applications, often leading to corrosion.
- plastic capillary tube mats are very suitable as a means of providing a heat exchange surface. They are very versatile in terms of their use, for example for shaping making cooling and heating ceilings, suspended cooling panels, etc., which simultaneously form enclosure surfaces of a room. The heat exchange takes place by heat conduction, convection and radiation. These constructions cause a room to be cooled but they can and should not produce intensive air cooling as a result.
- plastic capillary tube mats for cooling and heating rooms and/or water baths (DE 197 51 883 C2), which, amongst other things, also contain a spiral-shaped, wound plastic capillary tube mat.
- Characteristic of this construction is a foil disposed between the capillary tube mats, which has projections (protuberances), by means of which passages are formed. As one flow of substance flows through the capillary tube mat, the second flow of substance is directed through the passages formed by the foil. From a hydraulic point of view, the high pressure loss which occurs due to the flow resistance on the foil is a particular disadvantage. From a thermodynamic point of view, the solution based on the spiral-shaped winding has various disadvantages.
- the foil lies against the capillary tubes, which means it is not possible to produce a free flow round them, thereby reducing the external coefficient of heat exchange.
- the result of an arrangement with a capillary mat with a single inlet for the liquid flow is a cross-counter flow guide system with a low proportion of counter-flow due to the fact that the secondary flow of substance is axially directed. If opting for several inlets, the pressure loss in the capillary tube mat rises sharply. The temperature of the externally directed flow of substance is not uniform across the cross-section of the heat exchanger, which can be a particular disadvantage at the outlet.
- the underlying objective of the invention is to satisfy the objectives for the air cooling and air humidifying module set out below:
- a material corrosion-proof which is not susceptible to incrustation is used for the heat exchanger surface because plastic capillary tube mats are used.
- a good convective heat exchange is achieved at the heat exchanger surface through the transverse intake of the capillary tubes due to the short thermodynamic flow length achieved by the small diameter of the capillary tubes (as a rule smaller than 6 mm) and due to the circulation rate through the compact mat packet. This obviates the need for fin arrangements on the heat exchanger surfaces which are generally otherwise needed for heat exchangers, thereby providing an effective option for cleaning.
- a large surface is achieved in the smallest possible space due to the compact folding and/or winding technology so that the external geometry of the packet more or less assumes the shape of a cuboid. This fact offers ideal conditions for use in devices, in structurally restricted spaces, such as in ceiling cavities for example, and for replacing the heat exchanger element.
- a permanent shape can also be imparted to the mat packet solely and/or additionally by making use of the memory effect—for example by a thermal pre-treatment.
- a source air passage can be formed by opting for a specific perforation pattern in the housing and using an air flow direction system, or a rectangular free jet can be generated by integrating air circulation elements of a slotted shape or alternatively an air flow with a higher turbulence can be created by means of a helical air passage.
- a complete housing is dispensed with and if mat packets with a core region which can be used as a pressure chamber are employed, only blanking plates need be used for the core region, and at least one blanking plate is provided with an orifice for the incoming air.
- Sealing bodies are built into the lateral ends of the mat packets in order to prevent or reduce bypass air flows, which conditions the air flow uniformly as it circulates.
- the air flow distribution in the room to be air-conditioned can be further improved by encasing the mat packet in a foil with appropriate perforations or an appropriate fabric.
- One special option for improving performance i.e. for cooling air and dehumidifying air, is to use several mat packets disposed one after the other in the air flow in series, comprising folded and/or wound plastic capillary tube mats which are connected in counter-flow at the water end.
- several cold water inlets into the consecutive mat packets may also be provided.
- external air is directed partially or exclusively into the pressure chamber, as a result of which the external air flow which must necessarily be hygienic also undergoes a temperature and/or humidity change.
- the modules proposed by the invention are disposed so that an intensive air flow takes place along the pane, wall, etc., to be conditioned, if necessary using the Coandä effect.
- the air cooling and air dehumidifying module may also be used during periods when it is necessary to heat the room by using hot water, in which case it assists or fully takes over the function of heating the room.
- the output of the modules can be controlled by all known methods and combinations of them (varying the water inlet temperature, varying the water flow, varying the air flow volume, e.g. by speed control, shutting down individual fans, using gravitational force, etc.).
- the method is also designed to increase efficiency from the point of view of primary energy use because, if the system is designed to operate at a low cold water temperature—which causes dehumidification due to condensation of the water vapour in the air as desired—and as high as possible a cold water temperature is used for the cooling ceiling, the room is cooled with a low exergic flow—for example due to a high proportion of ambient energy.
- the ambient air can expediently be drawn from directly underneath the room ceiling, i.e. via the cooling surface.
- control zones for a group of air cooling and air dehumidifying modules in conjunction with the co-operating cooling ceilings and/or suspended cooling panels.
- control variables comprising the room temperature and air humidity of the room on the basis of mean values obtained from several measurement values.
- One advantageous solution for adapting output is to opt for a time control system, which is operated in anticipation of expected high load changes.
- an inactive range a so-called energy zero band—lies between the switching stages of the control system, in which case the room is not cooled and the air is not dehumidified within fixedly defined threshold values or one of these activities is deliberately dispensed with.
- Another option for simplifying automatic control is to regulate the room temperature only and operate dehumidification of the air on a passive basis so that the humidity of the room fluctuates freely within specific ranges based on a calculation of the humidity loads and the resultant dehumidification output calculated beforehand.

- shape 1 is imparted to the compact mat packet comprising plastic capillary tube mats by folding or shape 2 or 3 is imparted by winding, so that the external dimensions virtually assume the geometry of a cuboid.
- the mat packets 1 , 2 or 3 illustrated in FIG. 1 are disposed in a housing 11 , thereby forming a pressure chamber 12 , from out of which the air flow 10 passes through the mat packets into the room 9 to be air-conditioned.
- Cold water is circulated through the capillary tube mats forming the mat packet, so that the air flow 10 is cooled and also dehumidified (dried) when there is a drop below the dew point temperature.
- Any condensate which drops out is collected in the condensate catchment container 13 , from where it is removed by known methods, for example by pumping it out.
- An air pressure exists in the pressure chamber 12 which is higher than that in the room 9 . This is achieved by the action of a fan 17 , which removes the air flow 19 from the room 9 and conveys it into the pressure chamber 12 .
- FIG. 3 illustrates one option for thermodynamically improving the operating characteristic, because several mat packets, for example of design type 2 , are connected in series in the path of the air flow 10 and also the cold water is fed in counter-flow. To this end, the intake 14 lies outwards, the return 14 a lies inwards and the cold water connecting lines 16 are disposed as illustrated in FIG. 3 .
- using a mat packet of design type 3 offers the possibility of using the core region 6 as a pressure chamber 12 .
- the advantage of this variant is that as the cold water flows from outside to the interior, as indicated by the connectors 14 and 15 , there is always a thermodynamically optimum counter-flow. A very compact construction of the module is also achieved.
- FIG. 6 and FIG. 7 illustrate the mat packet based on design type 3 but fitted horizontally. Due to the low height, the air cooling and air dehumidifying module is particularly suitable for integrating in ceiling cavities, for example for use in conjunction with cooling ceilings or suspended cooling panels.
- the air flow 10 is able to pass into the room from three sides and the condensate catchment container 13 extends at least across the dimension 5 .
- the condensate catchment container is of a smaller design, for example reduced to a gutter, and the falling condensate is introduced via baffle surfaces disposed in a funnel-shaped arrangement.
- FIG. 7 also illustrates an example of integrated sealing bodies 21 to prevent leakage flows of non-conditioned air. It may also be practical to integrate these if mat packets abut laterally with one another.
- FIG. 8 to FIG. 10 illustrate details showing various dispositions of the fan or fans 17 .
- the air flow 19 out of the room 9 may enter from all sides of the housing in principle and then be conveyed into the pressure chamber 12 .
- the design of the fans 17 may be of any known type, although roller fans and axial fans are preferred.
- the advantage of roller fans is that they fill the pressure chamber with the air flow across a wide intake surface.
- FIG. 8 illustrates a solution with two fans 19 . This variant ensures that the air flow 10 is distributed uniformly through the mat pack in the event of a long packet length 20 .
- One fan can also be switched off in order to provide an automatic control system in stages. For this reason, it may also be useful to use additional fans 17 .
- FIG. 8 illustrates the direct mounting of the fans on the blanking plate 18 a , for example by mounting flanges.
- FIG. 9 shows the fan 17 integrated in the housing 11 .
- FIG. 10 illustrates the solution resulting in low pressure losses achieved by fittings to direct the air. These fittings may be connected to the housing 11 , the fan 17 or, as illustrated, to the blanking plate 18 b by a non-positive, positive and/or material connection.
- FIG. 11 illustrates one theoretical option for providing air cooling and air dehumidifying modules 22 in conjunction with a cooling ceiling 24 as well as their cold water connectors 14 , 15 , 14 a , 15 a and the automatic control system. From the point of view of exergic operation, it is generally of advantage if the air cooling and air dehumidifying module 22 is connected to a cold water network of low temperature which causes the water vapour from the air to condense on the capillary tube surface when there is a drop below the dew point and the cooling ceiling 24 is connected to a cold water network of higher temperature. This enables the cooling ceiling to be operated during a large period of the year by means of ambient energy, for example, which is picked up via a cooling tower or is drawn from an earth collector.
- the automatic control should preferably be undertaken by two control circuits.
- the air cooling and air dehumidifying modules 22 assume control of the air humidity and the cooling ceiling 24 assumes control of the room temperature.
- the parts of the control circuits are: humidity sensor 27 , humidity controller (hygrostat) 29 , temperature sensor 26 , temperature controller (thermostat) 28 .
- the actuators in the closed loops are actuator valves in the cold water connectors in the embodiment illustrated as an example. Generally speaking, however, other known systems could be used, for example an adjustment of the temperatures or in the case of controlling the output of the module 22 , varying the throughput of air through the mat packet, etc.
- the separately acting humidity and temperature control circuits ensure that the room is maintained in a predefined state.
- control circuits it would naturally also be possible to link their operation to one another, in which case the intended change of one controller is displayed to the other respective one, for example, e.g. in the form of a known disturbance feedforward, or the two controllers could be combined in a micro-computer, for example, and operate on the basis of a linked control strategy.
- FIG. 12 illustrates a simplified aspect of the control technology, whereby the air cooling and air dehumidifying module 22 and the cooling ceiling, in this instance illustrated as a suspended cooling panel 25 , are connected in series at the water end, and only a temperature control takes place by means of a sensor 26 and controller 28 .
- a sensor 26 and controller 28 Provided an exact load and power can be detected and the module 22 and suspended cooling panel 25 are dimensioned accordingly, the room temperature can be maintained exactly and the air humidity in the room kept within a range based on predefined threshold values.
- the power of the two components is correctly adapted and no condensation will occur on the cooling ceiling or on the suspended cooling panel, i.e. the entire system is intrinsically safe in this respect.
- circuit variant Y instead of variant X enables some of or the entire water flow between the cold water outlet 15 from the module 22 and the cold water inlet 14 a a into the suspended cooling panel 25 to be diverted.
- the advantage of using this variant is that it results in a controlled output distribution for the module 22 and the suspended cooling panel 25 .
- FIG. 13 Another special solution which can be of advantage in many applications is illustrated in FIG. 13 .
- an actuator 30 for example a blind
- a humidity sensor on the cooling ceiling or on the suspended ceiling panel may be used as a signal transmitter.
- FIG. 14 demonstrates one advantageous option for fitting air cooling and air dehumidifying modules 22 in conjunction with an opening cooling ceiling 24 a , so that optimum use can be made of the ceiling cavity.
- the air flow 19 is drawn from the room in the uppermost region of the ceiling cavity. This is of advantage because warm, moist air has the lowest density and collects in the upper region of the room. Accordingly, the highest temperature and partial pressure differences act on the surface of the plastic capillary tube mats and are conducive to the cooling and dehumidification outputs.
- the incoming flow 23 of cooled and dehumidified air can be directed to the vicinity of the wall without causing draughts for the room users.
- FIG. 15 to FIG. 17 illustrate advantageous possible ways in which an air cooling and air dehumidifying module 22 should be disposed so that it is effective in terms of heat engineering and in keeping with strict comfort criteria, together with a suspended cooling panel 25 .
- the air cooling and air dehumidifying module 22 draws the room air flow 19 at a distance of 50 to 100 mm below the suspended cooling panel 25 , for example, so that the rising warm air is still not pre-cooled by the convective action of the cooling surface 25 .
- the air flow 23 to be introduced back into the room passes out through the gap to the ceiling via the suspended cooling panel 25 so that the air flow into the room takes place outside of the area covered by the suspended ceiling panel.
- the main occupied areas for example the workplaces at desks, are disposed underneath the suspended ceiling panel as a rule, where they will feel the heat and physiologically pleasant effect of the radiation cooling, and the lateral outflow of cold air does not have an unpleasant effect.
- the architectonic design of the suspended cooling panel may be such that outflow areas of cold air occur close to the wall. These air flows are then distributed in the floor region in the same way as with the tried and tested source air intake.
- FIG. 16 shows the room air intake 19 in the top area of the room and the outlet from the air cooling and air dehumidifying module 22 which takes place at the side, e.g. by means of slotted nozzles, so that there is a blowing effect onto a passive suspended cooling panel 25 a —using the Coandä effect.
- the surface 25 a is therefore cooled as a result, causing a secondary effect of radiation cooling for the room.
- FIG. 17 shows an arrangement of the air cooling and air dehumidifying module 22 directly above the suspended cooling panel 25 which is particularly easy to achieve from a construction point of view.
- the room air flow 19 is drawn from the upper area of the room and the conditioned air flow 23 is blown out directly above the suspended cooling panel 25 , and the advantageous options of the other air directing system described in connection with FIG. 15 may be used.
- FIG. 18 illustrates an additional feature to example 7 described in connection with FIG. 11 , based on the advantageous option of the external air flow 19 a and the way it is air-conditioned in an air cooling and air dehumidifying module 22 .
- This enables a hygienically conditioned external air flow to be introduced, the size of which is defined depending on the number of room users or the volume of the room. It is of advantage that this air flow undergoes a change of temperature and humidity and thus largely enters the room as an incoming air flow 23 which has been adapted so as to achieve the comfortable room air state as far as is possible.
- another air cooling and air dehumidifying module 22 may operate on the basis of the known circulating air mode.
- Another improved aspect of the method incorporates a control of the external air volume flow 19 a depending on the time of day, occupancy of the room the quality of the room air, for example.
