Definitions

  • Sorption devices particularly sorption refrigerating machines, are known in the prior art.
  • Materials and substances located in a sorption system may outgas or, for example, release gases due to chemical conversion. These disruptive gases or vapors prevent a quick sorption process, since they render access of the vaporous working medium to the sorption agent difficult during adsorption or absorption and prevent or render difficult access of the vaporous working medium to the condensation surfaces, both of which lead to an extreme retardation of the generation of cold and heat. This results in a substantial decrease in the performance of these sorption systems.
  • the term “disruptive gas” refers here very generally to substances that influence the access of the working medium vapor to the sorption agent, thus preventing the sorption process (for example, carbon dioxide, nitrogen, etc.). The gases are also referred to as inert gases or foreign gases.
  • DE 44 44 252 B4 describes a method in which a binding agent is introduced into the sorption machine.
  • a binding agent is added to the sorption system.
  • the task of the binding agent is to bind the inert gases or vapors present or released in the sorption system, thereby removing them from the working medium vapor space. It must be capable of binding as much inert gas or vapor as is released in the sorption system through outgas sing or chemical reaction of the substances and materials contained therein.
  • the binding agent need only bind this specific quantity of inert gas within this time period.
  • all substances that are capable of binding inert gases or vapors occurring in a sorption system are suitable as binding agents.
  • the binding agent should be capable of not re-releasing the bound inert gas even in the event of system-related fluctuations in temperature. Since most binding agents tend to do so at high temperatures, the binding agent should be applied in a place where the temperatures are as low as possible and that are subject to only small temperature fluctuations.
  • the highest temperatures occur in the sorption agent container during sorption and desorption.
  • the binding agent is applied in an area in which there are relatively lower system temperatures, such as in the condenser, vaporizer or collecting receiver.
  • the invention concerns a method for removing a foreign gas from a sorption machine, wherein the sorption machine comprises at least
  • the inert gas trap is thus activated by one of the abovementioned control signals and thereby put into operation.
  • the removal of inert gas therefore does not occur at any point in time, but rather it is coordinated with the sorption process.
  • This leads to an increase in performance since the inert gas can thus be removed at an ideal point in time. In this way, a drop in performance as a result of the inert gas is prevented.
  • the performance of the sorption machine can therefore be increased, which ultimately leads to cost-savings.
  • control signal activate the inert gas trap as soon as predefined parameter values are reached.
  • parameter values relate either to the quantity of inert gas, performance, number of cycles or hours of operation.
  • the quantity of inert gas is preferably reflected by the inert gas partial pressure.
  • the condenser can be present as a separate condenser or in a combined vaporizer/condenser unit.
  • a desorber in terms of the invention is particularly present either as a separate desorber or in an adsorber-desorber unit.
  • an “inert gas trap” preferably refers to a device for removing inert gas from a sorption machine, particularly an adsorption machine, and especially preferably an adsorption refrigerating machine.
  • Inert gas can also be referred to as foreign gas.
  • a sorption machine can also be referred to as a sorption device.
  • the restrictor element is preferably selected from the group comprising valves, through valves, angle valves, inclined seat valves, solenoid valves, check valves and/or floats.
  • the restrictor element is preferably integrated into a connector and brings about a localized narrowing of the cross section of flow.
  • different valves which can be subdivided according to their geometric shape, can be integrated into a restrictor element. Through the use of the valves, the flow volume in the connectors can be metered exactly and precisely by changing the interior diameter and a reliable seal against the environment can be formed.
  • the restrictor elements can advantageously be actuated by hand, by medium, mechanically or electromagnetically.
  • the restrictor element that is arranged between the inert gas trap and the condenser be a valve, solenoid valve, slider, check valves, capillary pipe and/or a membrane. These preferred restrictor elements have proven especially suitable, because opening and closing is easy even in the presence of different pressure and temperature conditions.
  • the restrictor element be provided between the condenser and the inert gas trap with a control that opens the restrictor element as soon as greater pressure occurs in the condenser than in the inert gas trap.
  • the restrictor element is embodied as a float, the weight of the float must be sufficient to reliably seal an opening on which or against it is resting. During the desorption phase, the float is lifted by the working medium vapor flowing into the collecting receiver.
  • the float can be made, for example, of a plastic such as polypropylene.
  • a temperature sensor be arranged on the condenser and/or a pressure sensor on the condenser and/or desorber or the adsorber-desorber unit, the control signal depending on the measured values of the pressure and/or temperature sensor.
  • the quantity of inert gas be determined via the inert gas partial pressure.
  • the detection of inert gas is preferably done in the condenser and/or in the desorber.
  • An advantageous determination of the quantity of inert gas is performed via a temperature sensor that is arranged in the condenser.
  • a pressure sensor is preferably used that is arranged either in the condenser and/or in the desorber. Since both containers have the same pressure at the time of measurement, it is unimportant where the pressure sensor is arranged.
  • the temperature sensor preferably records temperature values, whereas the pressure sensor records pressure values. It is therefore especially preferred that the determination of inert gas be performed by means of a temperature and/or pressure measurement. In doing so, the measurements are performed with the abovementioned sensors. It has been shown that this is an especially precise and yet favorable method for determine the quantity of inert gas.
  • the temperature sensor not be arranged in the vacuum area of the condenser, but rather in such a way that the return temperature of the condenser is measured. It is therefore the outlet temperature of the working medium that is determined.
  • the condenser is particularly a heat exchanger that is supplied externally, i.e., not on the vacuum side, with recooled medium (preferably water). Internally, i.e., on the vacuum side, the working medium (preferably water) condenses on its surface. Three temperatures are of importance here: the flow and return temperature of the recooled medium (external) and the temperature of the condensed working medium (condensate, vacuum side).
  • the inert gas it is preferred that the temperature of the condensate be determined in a vacuum. However, since it is complicated to measure that temperature, it is preferably determined indirectly through the return temperature of the condenser.
  • the temperature in the vacuum area can be determined indirectly by measuring the outlet temperature.
  • the temperature measurement is taken when the condenser is not providing its full output. This can preferably be in the second half of a cycle, for example.
  • This embodiment is especially advantageous because especially accurate measured values van be generated in this way, thus enabling a very precise determination of the quantity of inert gas.
  • the vapor pressure of the working medium is preferably determined for the temperature of the condenser. This value is subtracted from that measured in the desorber and/or condenser. If no inert gas were present, the difference would be equal to zero. The pressure difference therefore corresponds to the inert gas partial pressure.
  • the activation of the inert gas trap be done by means of a control signal, with the control signal depending on the inert gas partial pressure.
  • Parameter values for the inert gas partial pressure are preferably determined which act as thresholds, the exceeding of which leads to the activation of the inert gas trap via the control signal.
  • the values for these thresholds depend above all on the size of the sorption machine as well as on the particulars of the device. Thus, the type of adsorption or absorption agent also determines the level of the threshold.
  • the inert gas trap is activated or switched on when a certain quantity of inert gas, that is, a certain inert gas partial pressure is reached.
  • a certain quantity of inert gas that is, a certain inert gas partial pressure.
  • the coordination of the removal of the foreign gases with the mode of operation of the sorption device offers an advantage compared to the inert gas trap without this control element, since better sorption performance can now be achieved.
  • the inert gas trap is already activated at an inert gas partial pressure that has not yet led to a drop in performance, or only to a small drop in performance. The performance, preferably the cooling performance is thus always maintained in an effective range. In the prior art, this was not possible in such a simple and precise manner.
  • Another preferred method for activating the inert gas trap is a performance-dependent control signal.
  • This signal is influenced by the drop in performance.
  • the drop in performance is preferably determined through a measurement at the vaporizer. This measurement is preferably performed using a temperature sensor. This temperature sensor measures the temperature of the incoming and outgoing working medium. If the temperature difference drops, this is an indication of a drop in performance.
  • a threshold is now established for a preferred embodiment of the invention after which the inert gas trap is activated.
  • the performance preferably the cooling performance
  • the threshold is selected such that the inert gas trap is activated as soon as a measurable drop in performance occurs.
  • the use of the number of cycles as the activation signal is also preferred.
  • the number of cycles of the sorption device is meant.
  • This embodiment can also be advantageous. It is a statistical activation signal. Therefore, no measurement is taken of certain parameters using sensors, but rather a number of cycles is established as the threshold. When this number of cycles is reached, the inert gas trap is activated by means of the abovementioned steps.
  • the advantage of this method is, above all, the simplicity of implementation. For instance, no special sensors need be installed.
  • This method is particularly well suited to sorption machines that are already in operation and for which empirical data are available.
  • it can also be preferably for the optimum number of cycles to be determined by means of pressure and temperature measurements. In that case, it is checked on the basis of the previously described inert gas determination at what number of cycles the inert gas thresholds were reached. The control signal is then based only on the number of cycles. It is no longer necessary to measure temperature and pressure.
  • the determination of the threshold according to number of cycles or time of operation depends on many factors. Among other things, the type of the adsorption or absorption agent is important. The size of the sorption device also plays an import role. A person skilled in the art knows how to establish the optimum number of cycles or hours of operation without inventive step.
  • step d. i.e., the heating of the inert gas trap
  • step d be initiated by the control signal and the sequence of the steps begin at step d.
  • the preferred sequence is therefore step d, step e, step a, step b, step c, step d, step e.
  • step d offers the advantage that inert gas that might have gotten into the inert gas trap from the environment is first evacuated. Inert gas may have gotten into the inert gas trap especially if the inert gas trap has not been operated for an extended period. As a result, ambient air may have happened to penetrate into the inert gas trap. By starting at step d, additional inert gas is thus prevented from getting into the system. The inert gas trap is therefore first evacuated as a precaution before step a begins. This embodiment has proven to be especially preferred, since this prevents additional inert gas from getting into the device that would then have to be removed.
  • the method preferably always ends with step e.
  • the present application includes the disclosed content of W02012069048. That application concerns a “Vacuum container for removing foreign gases from adsorption refrigerating machine.”
  • the vacuum container described therein is a preferred embodiment of the inert gas trap in terms of the invention.
  • the novel method according to the invention is not limited to adsorption devices. After all, the problem of the removal of foreign gases is just as relevant to absorption, for example. The method according to the invention can therefore be implemented in all sorption machines with an inert gas trap.
  • the working medium is a refrigerant, preferably water.
  • the inert gas trap can also preferably run a certain number of cycles/procedures.
  • the sequence of steps a to e is preferably repeated multiple times.
  • the number of repetitions depends on the size of the inert gas trap. 10 to 150 repetitions are preferred, for example, and 50 to 100 repetitions are especially preferred. 75 repetitions are very especially preferred. If the inert gas trap is large enough, however, one pass through the steps is also sufficient in order to completely remove the inert gas. A person skilled in the art knows what number of repetitions is especially preferred for the respective configuration of the inert gas trap and sorption device.
  • any small quantity of inert gas be removed immediately or to postpone removal until a higher threshold is reached, and the inert gas trap is activated only then. This applies to all of the abovementioned parameters. Where the appropriate threshold lies depends, in turn, on many individual factors and cannot be generalized.
  • the point in time at which the determination is made is important, and the determination is based on at least one of the following criteria:
  • Determination of the quantity of inert gas in the middle or toward the end of the cycle is especially preferred.
  • the optimum point in time for determining the quantity of inert gas is also depends on the sorption device being used.
  • a person skilled in the art is capable of executing the invention such that they are able to determine the appropriate point in time for determining the quantity of inert gas depending on the sorption device.
  • the quantity of inert gas that is, the inert gas partial pressure
  • the determination of 5 to 100 values in a period of 5 to 150 seconds is preferred above all.
  • the measurement of 30 to 75 values in 10 to 25 seconds is very especially preferred.
  • An average is preferably formed from these values which then determine the quantity of inert gas. By forming the average from several successive measurements, small fluctuations are equaled out, and the quantity of inert gas can be determined especially accurately.
  • the method of the invention therefore includes a control concept in which the inert gas trap is activated by a control signal, thus establishing when the inert gas flows out.
  • the entire sorption process can be improved, and increased performance is achieved.
  • Such an inert gas trap can also be described as a vacuum container for a sorption device, characterized in that the vacuum container is connected via vapor-open connection means to a condenser unit of a sorption refrigerating machine and the container has a discharge device and at least one component for locking or regulating the flow of fluids.
