    The invention relates to a method for using the waste heat of a data processing system with a plurality of processors by means of a cooling water circuit.
    In addition, the present invention also relates to a system for carrying out the method mentioned above for using the waste heat of a data processing system with a plurality of processors, with a cooling device for dissipating the waste heat and with at least one device for utilization of the waste heat of data processing system.
    The Internet use is growing rapidly and leads to a deterioration of the climate, because the hunger for energy of the data network is hard to quench. Especially the mainframes of companies consume tons of electricity. It is assumed that the CO2 emissions of the entire Internet are now as high as those of global air traffic. Airlines, airports, air navigation service providers and manufacturers have committed to improve energy efficiency by 1.5% per year by 2020, to limit net carbon emissions by 2020 and by 2050 by 2020 half compared to 2005. Air traffic accounts for 2% of global CO2 emissions, equivalent to around 650 million tonnes of CO2 per year in the transport of 5 billion passengers and 46 million tonnes of cargo. Assuming that the worldwide compiled to so-called server farms and having a plurality of processors data processing systems have at least a comparably large CO2 emissions, the challenge arises to significantly reduce the global CO2 emissions of such server farms.
    From DE 10 2007 062 143 B3 already known a method and a system of the type mentioned, which is intended to use the waste heat of a computer system with a plurality of processors. Here, the previously known method provides that the waste heat of the processors is removed by a cooling device and transmitted to at least one device for utilizing the waste heat. The device used to utilize the waste heat may be designed as a heating system or as a system for providing hot water. But it is also possible that the waste heat of the processors provided in the computer system has to drive a heat engine.
    WO 2010/022 800 A1 is already known a so-called aquaponic system, which combines a specific for fish farming aquaculture with an intended for the cultivation of aquatic plants hydroponic unit. In this case, the previously known plant provides that the aquaculture unit has at least one water outlet, which is so functionally connected via a one-way valve with the hydroponic unit, that the water from the aquaculture unit of the hydroponic unit can be supplied. Thus, the used water flows to the aquaculture unit of the hydroponic unit. There, the water is used to water the plants and provide them with nutrients. The plants take the water and the nutrients, i.a. Nitrate, and then, by means of plant transpiration, return the water without nutrients to the air in the hydroponic unit. This transpiration water of the plants is collected by means of a cold trap in the hydroponic unit and returned to the aquaculture unit. This results in a closed water cycle in the previously known aquaponic system, in which the plants of the hydroponic unit serve as a natural filter for nitrate and as a natural corrective for the pH of the water. The previously known aquaponic facility must have the u.a. Energy required for temperature regulation of the water from the outside, for example via a photovoltaic system, are supplied.
    It is therefore an object to provide a method and a system of the type mentioned above, which allows the CO2-reduced or even CO2-neutral utilization of the waste heat generated in a data processing system.
    This object is achieved by a method according to the features of claim 1 and a system according to claim 8. Advantageous embodiments of the method or system are the subject of the dependent method claims and the dependent system claims.
    In the method of the type mentioned, the inventive solution to this problem is that the waste heat is used to heat at least one intended for aquatic plants or animals rearing tank.
    The inventive method aims at the CO2-neutral use of waste heat from a data processing system, which has a plurality of processors. In order to dissipate the waste heat generated in particular in the processors of such a data processing system, a cooling water circuit is provided. The waste heat is used to heat at least one breeding tank for aquatic plants or animals. While the waste heat has to be dissipated from the data processing system, the rearing of aquatic plants or animals in a heated rearing tank is much favored.
    A further solution to the above stated problem, which can be implemented in addition to or instead of the inventive proposal already described above, provides that the waste heat is used to heat a arranged below a plant cultivation area floor heating. The growth conditions of the plants grown in the process according to the invention are substantially favored when the root system of these plants located in the soil finds improved and in particular heated soil conditions.
    An approximately 500 m <2> large server farm requires annually about 860 000 kW / h of electricity. With a saving of 50%, the consumption could decrease by 430 000 kW / h. Since CO2 emissions per kW / h were 559 g in 2013, it would be possible to save around 240 370 kg of CO2 per year in a server farm with the aid of the method according to the invention. In addition, a saving of heat can be achieved in a breeding pond for aquatic plants or animals, which can easily provide up to 2.2 million kW / h of heat savings. For a gas CHP, 1 kW / h of heat would produce about 260 g of CO2, so that a further savings of about 572 000 kg CO2 per year can be achieved. If one adds the total CO2 savings which can be achieved in the process according to the invention, then in a server farm operated according to the method according to the invention, 812,370 kg of CO2 could easily be saved compared to conventional plants.
    In this case, an embodiment according to the invention is preferred in which the waste heat is first used to heat the at least one rearing tank and then to heat the floor heating.
    In the at least one breeding tank aquatic 'plants, crustaceans and / or fish can be reared. A particularly simple and advantageous embodiment according to the invention provides that the at least one rearing tank is used for aquaculture or for hydroponics.
    In order to dissipate the waste heat not only of the processors, but the entire data processing system, it is advantageous if the cooling water circuit is used for cooling of racks and / or server cabinets of the data processing system.
    The living in the breeding tank plants or animals in turn generate CO2, which can increase the growth of plants located on a plant growing area. A particularly advantageous development according to the invention therefore provides that the exhaust air of the at least one rearing tank is fed to the plant cultivation area.
    In order to favor the optimal utilization of the waste heat generated in the data processing system in addition, it may be premature if the waste heat is used to heat office or living spaces and if this office or living space are preferably heated by means of a floor heating.
    In the aforementioned system for utilizing the waste heat of a data processing system, the solution according to the invention of the above-described object is that the at least one device is a breeding tank for aquatic plants or animals and / or that the at least one device is a plant cultivation area ,
    The heat generated in a server farm or the like data processing system waste heat can be used particularly easily and advantageously a further use in a subsequent device in the cooling circuit when the cooling device has a water cooling circuit for dissipating the waste heat.
    In this case, a particularly simple and preferred embodiment according to the invention provides that the water cooling circuit is passed over the at least one rearing tank.
    In order to favor the growth of standing on a plant acreage plants, it is advantageous if the water cooling circuit is guided by a bottom heating, over which the plant cultivation area is provided.
    The optimum utilization of the waste heat generated in the data processing system is further favored when the water cooling circuit is guided by a floor heating, which is used for heating office and / or living space.
    In order to realize the inventive system in a particularly compact and space-saving plant, provides a preferred embodiment according to the invention, that the plant acreage and the breeding pool are provided in superposed floors of a building. In this case, such a building can also be formed from one above the other and adjacent containers.
    Compared to the aquatic plants or animals, plants planted on a plant surface require as much sunlight as possible. It is therefore advantageous that the plant acreage is provided in the attic of the building and that the attic is glazed at least partially.
    Since the standing on a plant acreage plants require regular water additions and because these plants love the addition of warm water, it is advantageous if a cooling water tank is interposed in the water cooling circuit, and if a drain of the cooling water tank to the at least one rearing tank or the at least one plant acreage leads to the removal and use of cooling water as useful water.
    On hot summer days, the removal of the heat generated in a data processing system waste heat may not be ensured to a sufficient degree. In order to ensure adequate cooling of the data processing system on such hot summer days, it may therefore be advantageous if at least one water cooler can be switched into the water cycle as required.
    In order to control the cooling circuit as needed and regulate the optimal temperatures in the rearing tank on the one hand or in the field of plant cultivation on the other hand, it is expedient if the cooling device is assigned an electronic control unit with at least one temperature sensor for measuring the cooling water temperature and is in control connection with at least one control valve for the guidance of the water cooling circuit.
    Further developments according to the invention will become apparent from the claims in conjunction with the drawings and the description. The invention will be described in more detail below with reference to preferred embodiments.
    It shows:<Tb> FIG. 1 is a schematic illustration of a system for utilizing the waste heat of a data processing system, this system comprising a cooling device for removing the waste heat and devices for utilizing the waste heat of the data processing system, and<Tb> FIG. 2 is a system comparable to that of FIG. 1, in which both the data processing system and the devices for utilizing the waste heat generated in the data processing system are accommodated in superposed floors of a building.
    1 and 2, various embodiments of a system are shown, which is intended to use the waste heat of a data processing system 1. The system shown in FIGS. 1 and 2 has a data processing system 1, also referred to as a server farm, with a plurality of processors. The operation of this data processing system 1 and in particular also the processors therein is associated with a high heat development. In order to dissipate the waste heat of this data processing system 1, a cooling device is provided which has a water cycle. This water cycle is indicated in Figs. 1 and 2 by arrows provided with arrows.
    In Fig. 1 it can be seen that the cooling device for cooling the racks or the server cabinets 2 of the data processing system 1 is used. The water coming from the data processing system 1 and heated there is first supplied to at least one rearing tank 3, which is used for rearing aquatic plants or animals. The rearing tank 3 may be provided in particular for aquaculture or serve as a hydroponic unit to raise as large amounts of food serving as plants, shellfish and / or fish.
    As indicated in Fig. 2, the system may also include a variety of such breeding tanks 3, which can also be used differently if necessary. After the guided in the cooling water circuit water has heated the temperature in the rearing tank 3, for example, 20 ° C to 24 ° C, this is the waste heat of the data processing system 1 transporting cooling water then a bottom heating 4, above which a plant cultivation area 5 is provided. In this plant growing area 5, the bottom surface is heated by means of the bottom heating 4 such that the plants located there find 6 optimal cultivation conditions. In order to further promote plant growth, the exhaust air in the region of the at least one rearing tank 3, which has been enriched by the plants or animals with moisture and with CO2, in the area of the plant growing area 5 can be continued. Here, the warm and humid climate and the increased CO2 concentration there favor the rapid growth of plants 6.
    In Fig. 2 it is indicated that there distributed over the floors 0, I, II and III of a building 7 system may also have a cooling device, the cooling water circuit is passed through a floor heating 8, for heating office and / or living space serves. In the system shown in Fig. 2, for example, the plant cultivation area 5 and the breeding tanks 3 are provided in superposed floors I and III of the building 7. The plant cultivation area 5 is provided in the attic III of the building 7, which attic III is at least partially glazed. Since the attic III of the building 7 is glazed here over its entire roof surface, a high solar radiation in the area of the plant growing area 5 is achieved.
    In Fig. 1 it is indicated that in the cooling water circuit, a cooling water tank 9 may be interposed, the process, for example, leads to the rearing tank 3 and / or the plant growing area 5 to allow the removal and use of cooling water as useful water there. In located in the lower or ground floor 0 data processing system 1, the guided in the cooling water circuit cooling water is heated. The heated cooling water is then fed to the rearing tank, where the heat is used for the rearing of fish, crustaceans and / or aquatic plants. In the breeding tank 3 is a cooling of the cooling water. From the rearing tank 3, the cooling water, optionally through the underfloor heating 8 through, led to the plant acreage 5, which forms a roof farm in the attic III. In the area of the plant cultivation area, the cooling water guided in the water cycle is cooled down even further, in order subsequently to be supplied to the cistern 9 in the cooling water circuit. In the cooling water cistern 9, the cooling water is heated to a hand warm temperature, so that the cooling water can then be used as useful water and, for example, the plant 5 located on the plant surface plants 6 can be supplied, especially since the plants love 6 especially lukewarm water. The water cooled down from stage to stage is then returned to the data processing system 1, where it is again heated by the data processing system 1, so that the cooling water circuit can then start again from the beginning.
    In Figs. 1 and 2 is not shown that the cooling device of the systems shown here may also be associated with an electronic control unit having at least one temperature sensor for measuring the cooling water temperature and at least one control valve 12 for the leadership of Cooling water circuit is in control connection. With the help of this control unit, the cooling water circuit can be changed in the devices used for the use of waste heat and adapted, for example, there optimal temperature conditions. For hot summer days, it may be advantageous if in the cooling water circuit as a precaution, a cooling unit 11 is switched on, with the temperature of the back flowing to the data processing system 1 cooling water can be additionally lowered.
