Definitions
- Ammonia water absorption refrigeration machines are considered large, heavy and expensive and their energy efficiency is significantly lower than that of compression refrigerators. In connection with renewable energies, however, there are new approaches in refrigeration, which are trying to make the ammonia-water absorption again interesting.
- Ammonia concentration of the solution leaving the digester or generator in a second step, called “bypass”, continues to lower before it passes into the absorber and finally one experiments with these machines with a plate construction, which allows complex piping systems, such as for absorption chillers, connecting in a single block of plates as a multilevel system, analogous to the design used in electronics for microchips.
- the present invention therefore describes a possible architecture of such intermittent ammonia-water Absorpionshimltemaschinen in batch process including bypass system, which allows an integration of control elements and thus in the immediate context, a specifically adapted to this design steam pump without moving parts, which can be controlled accordingly , State of the art
- Sole steam pumps operate at a low frequency because the medium to be transported has to absorb heat itself in order to generate the necessary pressure. After that fresh cold solution has to be sucked in again. .This is done by a self-acting pressure reducer, which is a cold liquid volume through which bubbles at the end of the Pumpaustreibvorgangs gas from the pump chamber and thereby absorbed.
- Waste heat accumulates at several points in ammonia-water absorption chillers. On the one hand, one has to differentiate between hot components such as the rectifier and the zone in the inlet area of the absorber, where the hot solution flows from the generator into the absorber and, on the other hand, only warm components, such as the absorber itself.
- the condenser also gives off heat, but its temperature should be just above the ambient temperature and it is therefore uninteresting
- Heat recovery '' 'in ammonia water absorption chillers namely between the cold solution flowing into the generator and the hot solution flowing out of it can not take place in a steam pump baten system. For one thing, even the steam pump heats up the solution before it enters the generator and, on the other hand, entry and exit of solution on the generator do not take place simultaneously, since it is a batch system.
- the most significant amount of energy is the amount of energy that can be recovered from the absorber, but it is assumed that the absorbing solution is cooled slowly over a longer path while synchronously increasing the concentration of the solution while the pressure in the absorber remains constant.
- the absorber also states that the released heat of absorption, which can be obtained per degree Celsius cooling of the absorber solution, is much greater at low temperatures than at high temperatures Displacement of the temperature intervals between the absorber and the generator thus has the consequence that the upper temperature range of the absorber recooling can be used in the lower temperature range of the generator heater, but that the amount of heat that can be recovered is less than half the energy requirement of the generator in this overlapping temperature range , On the other hand, this means that more than half of the resulting absorber heat is not yet used.
- Another method for improving the efficiency at low cooling and at high recooling temperatures is to continue to boil the solution coming from the generator in a second generator at a pressure level that is between the absorber pressure and the generator pressure and the Lösimg coming from the absorber a second absorber, which is at this medium pressure with this steam in contact before being pumped into the generator. Therefore, part of the ammonia does not circulate through the condenser and the evaporator, but returns to the first generator via a bypass called "bypass.”
- the second generator and the second absorber are better called the bypass generator and bypass absorber for clarity
- shaped plates made of hard material, preferably swelling material
- Fiberglass sealants which are perforated through holes and channel-shaped cut-outs and serve to conduct liquids or gases, and metal-foil separator plates in which holes are made for passage of liquids or gases perpendicular to the plate plane. This stack is pressed together by screws, clamps or other mechanical means between two stronger metal outer plates, so that between each two mold plate a partition plate and between two Tr.ennpla.tten a mold plate comes to rest. See AT 506 358 ßl
- Verdam pamping given, which in turn is determined by the recooling temperature.
- cooling temperature control in an ammonia-water absorption refrigeration machine would already be possible (see AT 504 399 B1 - response 6) if the solution concentration of this machine is changed.
- the method mentioned in the cited patent is not to verwh'klkhen in the targeted plate concept here.
- the temperature in a room to be cooled could only be kept constant by means of a "stop and go” operation, if fluctuations in the recooling temperature m are expected, but it can take up to half an hour to start up the cooling system after a shutdown.
- the slow start process is also related to the fact that said damping pumps need a starter, the solution presses into the pump chamber, this process often has to be repeated several times. until the machine starts.
- serpentine absorbers very limited.
- the generator there is another problem with serpentine channels: the resulting gas accelerates the liquid between the gas biases so that the residence time of the liquid is much less than had been planned.
- Throttles are common in chillers, but they do not work well in barch systems, as the intermittent flow also has large pressure fluctuations, which also lead to large fluctuations in the flow in a throttle. Float valves could solve the problem of intermittent flow, but it is very difficult to fit them between tight plates.
- check valves are known as "umbrella valves", which are small valves made of elastomers, but because of their small size the through-holes are very small and tend to clog when in the solution which is unfortunately very common in the fiber composites mentioned
- this architecture must be designed in such a way that large chillers made of several identical modular small mesh lines can be assembled in a compact manner.
- Plate block on both outer sides Thick plates for containers, thermal insulation with distribution channels and static resistance to pressure from the inside, which continue the stacking of the plate block. These outer panels are around some
- Plate blocks in the middle of a vertical indentation in the control elements such. Magnet enile can be installed, which is then directly between the
- a variant of the bypass system which is also suitable for experienced users, is that a pre-spoke is fitted in front of the bypass absorber. in which the first steam pump dosed exactly (therefore you need a control) pumping solution from the main absorber. From this Vorell the solution of the
- Funnel-shaped ball check valves that can be installed vertically in the thick plates are made separately out.
- a rectangular opening is made for the valve in the top and bottom inlet and outlet channels open and the finished valve including ball is pressed into this opening with previously used above and below sealing rings in the gap between valve and plate.
- Absperrmitlel is interrupted by the upper end of the upper chamber in a separate part of the absorber memory, in which there is always solution because the absorber outlet opens into this part de absorber memory and from there flows through an overflow in the rest of the absorber memory, this is
- the first medium is the actual heating medium that the Heated one behind the other generator plates, this heating medium in the
- the condensate must have a reservoir at its outlet, where liquid ammonia is released before it reaches the shut-off point, which is used as a pressure booster
- Evaporator is used. And it must be guaranteed that there is always a certain minimum amount of weak solution in the absorbers, which can absorb the ammonia gas as soon as it is switched on as soon as the shut-off device at the condenser outlet is opened.
- This memory at the capacitor output has the additional positive effect that one during the operation of the machine by different
- Control of shut-off can store different amounts of liquid ammonia, which are thereby deprived of the rest of the system. The more
- the controllable cooling temperature of each individual module in a large machine can be used to further increase the COP: the medium that brings the cold into a room that is to be cooled is significantly warmer
- Chiller back If you now set the cooling temperatures of the individual modules so that the module through which the returning refrigerant medium flows first is the warmest and the module is the coldest, where the medium flows through last, before it goes back to the refrigerator, the average cooling temperature of modules higher than the nominal cooling temperature of the whole machine. However, as the COP depends heavily on the cooling temperature and is larger at warmer cooling temperatures, it saves energy.
- Thermal insulation panels which also serve as static elements against overpressure in adjacent zones and also can accommodate channels that not only run each other without crossing, but even against each other are thermally insulated.
- the distance between the two can be joined, so that a larger machine can be assembled from several identical modules.
- the liquid ammonia storage at the condenser outlet allows the cooling process to start immediately when the machine starts.
- this memory can serve to control the cooling temperature of the machine with appropriate control of the capacitor output control.
