Definitions

  • the invention relates to a sorption cooling system comprising a cooling container and an adsorption container.
  • compressor cooling units essentially consist of a, mostly hermetically sealed, compressor, a forced-cooled condenser, a collecting container for the liquid refrigerant, a temperature-controlled expansion valve and an evaporator.
  • the cold generated in the evaporator must be temporarily stored in a cold buffer, since the evaporator capacity is significantly lower than the cooling capacity required during a dispensing process.
  • the compression device has a longer running time than the sum of the individual tapping operations.
  • Today's cold buffers either have a water tank with a capacity of up to 20 l or a large aluminum block.
  • the biggest disadvantage of the aluminum block is that the storage capacity is relatively small, so that when more than 0.5 l of liquid are drawn, the cooling effect is already exhausted.
  • the water storage device has the disadvantage that after filling the water, the device must be in operation for a long time in order to cool the water filling itself.
  • the water tank must be provided with an additional agitator, which the water around the evaporator and cooling coils for better heat exchange pumped around. This mechanical agitator is extremely susceptible to failure and therefore often leads to the failure of the entire cooling device.
  • Such compression refrigerators are used to cool beverages, e.g. B. beer, lemonades etc. used in marquees or at parties. Your use in the private individual z. B. for cooling a borrowed beer barrel is only possible to a limited extent, since the high complexity of the device requires a lot of technical expertise from the user and the refrigerator cannot be used profitably for the beverage publisher due to the high acquisition or maintenance costs.
  • Sorption apparatus is understood to mean devices in which a liquid or solid sorbent sorbs a second, higher-boiling agent, the working fluid sorbs with heat release. Before the working medium is sorbed by sorbent, it evaporates in a cooling container while absorbing heat. The evaporation temperatures range from -40 ° to + 40 ° C, depending on the type of working fluid or the area in which the sorbent is used. Sorption devices with solid adsorbents, so-called adsorption devices work periodically, i. H. A sorption phase is always followed by a desorption phase in which the working fluid is separated from the adsorbent. The working medium cannot be sorbed during the desorption phase and therefore cannot evaporate. There is therefore no cold in the cooling container.
  • a periodically operating adsorption cooling apparatus in which an ice bank is built up during the adsorption phase by partial evaporation of the working medium water.
  • the apparatus exists thereby from an adsorption container which is filled with the sorbent zeolite, a cooling container which contains the working medium water and from which a vapor channel between the adsorption container and the cooling container can be shut off by means of a shut-off device.
  • Cold for example for cooling a cooling bag, can be dissipated via the container surfaces of the cooling container, while heat can be called up via the container walls of the adsorption container.
  • the working medium is desorbed from the sorbent by supplying desorption heat to the adsorption container and reliquefied in the cooling container with heat being released.
  • the shut-off device is closed and the adsorption container is cooled. In this state, the adsorption apparatus can be stored for any length of time.
  • the object of the present invention is to show a sorption cooling system which is characterized by a simple and inexpensive design and with the aid of which larger amounts of liquid can be cooled to temperatures between + 4 ° and + 10 ° C from any initial temperature with little control effort.
  • the sorption cooling system consists of a transportable cooling unit and a stationary charging station that can be separated therefrom. With a single charging station, a multitude is more portable Cooling units can be regenerated. In order to keep the cooling units easily transportable, they only consist of the technically absolutely necessary parts, namely an adsorption container filled with an adsorbent, a cooling container that contains the liquid working fluid and a heat exchanger embedded therein, a working fluid vapor channel that connects the adsorption container with the cooling container connects and a shut-off device that makes the steam channel shut off.
  • the working fluid When loaded, the working fluid is separated from the adsorbent as a liquid in the cooling container.
  • the shut-off device is closed, adsorption and working media are at ambient temperature.
  • the cooling unit can be delivered to the customer, e.g. B. can be borrowed together with a beer keg.
  • the customer connects the beverage lines to the heat exchanger and opens the shut-off device.
  • the working fluid can now evaporate in the cooling container, flow via the working fluid vapor channel to the adsorbent and can be adsorbed by the latter with the release of heat.
  • the heat of adsorption is dissipated via the walls of the adsorption container, for example to the ambient air.
  • the adsorption container can also advantageously be coupled to a water container, the water content of which can absorb the heat of adsorption.
  • the evaporation of the working fluid creates cold in the cooling container, which cools the medium flowing through the heat exchanger, for example a beverage.
  • the outlet temperature of the beverage can be regulated by temperature-controlled opening and closing of the shut-off device.
  • Zeolite is a crystalline mineral that consists of a regular framework structure made of silicon and aluminum oxides. This scaffold structure contains small cavities in which water molecules can be adsorbed with the release of heat. Within the framework structure, the water molecules are exposed to strong field forces, which liquefy the molecules in the lattice and bind them in a liquid-like phase. The strength of the binding forces acting on the water molecules depends on the amount of water already contained in the structure and the temperature of the zeolite. For practical use, up to 25 grams of water can be adsorbed per 100 grams of zeolite. Zeolites are solid substances without annoying thermal expansion during the adsorption or desorption reaction. The framework structure is freely accessible from all sides for the water vapor molecules. The cooling unit can therefore be used in any position.
  • the cooling capacity of the cooling unit is determined by the amount of zeolite filled in and the adsorbent temperature reached at the end of the tap time. This amount can therefore be designed so that one cooling unit is sufficient to cool a complete beverage container (beer keg, lemonade container, etc.).
  • the adsorption container After returning the discharged cooling unit, it is placed with the adsorption container in an opening in the heating cabinet of the charging station and desorbed. During this charging process, the adsorbent is heated and the working fluid is evaporated. The vaporous working fluid is re-liquefied in a suitable heat exchanger and returned to the cooling tank. The temperature of the heating cabinet is between 250 ° and 350 ° C at the end of the charging phase. As soon as the adsorbent is heated up and the working fluid is desorbed, the shut-off device is closed and the entire cooling unit is separated from the charging station. The adsorption container can now cool down but cannot draw off any water vapor from the cooling container. The cooling unit can be stored at room temperature until the next use.
  • the charging station Since the charging station remains with the respective rental company, it represents only a one-time purchase. All expensive and heavy components, such as electrical heating, temperature control, insulation of the heating cabinet and additional components such as evacuation unit, cooling fan, etc. can be mounted on the charging station.
  • the portable cooling unit is therefore light and inexpensive. It therefore does not need its own energy connection for the customer.
  • the cooling capacity is immediately available. In addition, it is characterized by a high cooling reserve, so that longer tap operation is possible. After removing the cooling capacity, the cooling unit is worthless to the customer without a separate charging station. He therefore willingly returns them to the lender against reimbursement of his pledge.
  • the further heat exchanger of the cooling unit via which the heat of condensation of the working fluid vapor is removed during charging in the charging station, can advantageously be a container wall of the cooling container.
  • the charging station can advantageously be equipped with a cooling fan that blows ambient air onto the container wall of the cooling container intended for condensation.
  • this heat exchanger is surrounded by the liquid working fluid according to the invention, it must protrude from the liquid working fluid for this purpose. This is achieved, for example, by rotating the cooling container when it is introduced into the heating cabinet to such an extent that the heat exchanger at least partially protrudes from the amount of liquid working fluid. Tap water can flow through the heat exchanger for cooling.
  • the shut-off device is required to have a high level of vacuum tightness, particularly when using the pair of zeolite / water substances. Furthermore, the shut-off device be designed so that it opens automatically and allows the working fluid vapor to flow into the cooling container as soon as the vapor pressure in the adsorption container is higher than the vapor pressure in the cooling container. In this way it is ensured that during the desorption phase, if the shut-off device is accidentally closed, no excess pressure can arise in the adsorption container.
  • the cooling unit can be equipped with an overpressure safety device.
  • a droplet separator can be arranged in the cooling container, which retains droplets of working fluid that arise during the evaporation process.
  • the adsorption container is advantageously designed so that desorption heat can be supplied via its container walls in the heating cabinet or the adsorption heat can be removed during the adsorption phase.
  • Flat containers which are connected to one another via the working medium steam duct, are particularly suitable for this purpose.
  • the amount of adsorbent expediently contains steam channels through which the inflowing working medium is evenly distributed.
  • the transportable cooling unit shown in perspective in FIG. 1 consists of six flat adsorption containers 1, which are connected to one another and to the cooling container 3 via a working medium steam channel 2.
  • the working medium steam channel 2 can be shut off via a shut-off device 4.
  • In the lower part of the cooling container 3 is the inlet and outlet 5.6 to the heat exchanger, not shown.
  • Cooling fins 7 are arranged on the outer wall of the cooling container 3 and increase the surface area in order to improve the dissipation of the heat of condensation into the ambient air.
  • the stationary charging station is also shown in a perspective view.
  • a heating cabinet 8 is provided with an opening 9 in which the adsorption containers 1 of the cooling unit can be accommodated.
  • a recess 10 is provided at a corresponding point in the heating cabinet, which allows the lid 11 of the heating cabinet to be closed after the adsorption container 1 has been inserted.
  • the cooling container 3 is located via two cooling fans 12, 13, which press ambient air onto the cooling fins 7 of the cooling container.
  • the cooling container 3 is shown in section.
  • a heat exchanger 14 with inlet or outlet 5, 6, embedded in a quantity of water 15.
  • a droplet separator 17 is arranged above the ice layer 16.
  • a broiled opens into the upper part of the cooling container Chen illustrated working medium steam channel 2.
  • the shut-off device 4 consists of a metallic bellows 18 and a flat seal 19 which rests on the mouth of the working medium steam channel 2 in the closed state.
  • cooling fins 7 are attached to enlarge the surface.
