    - 100% ecological
    - Help to care for the environment.
    - Drinking water and ice savings
    - Avoid the consumption of plastic bags for ice transport.
    The invention is intended for commercial, domestic and industrial use and covers a wide range of products: - Cooler for both solid products and beverages - Portable refrigerator always cold. -Fixed refrigerator. -Fridge freezer.
    It has its field of application in the manufacturing and manufacturing industry of refrigeration devices for food and beverages and more particularly in the manufacturing industry of refrigerators refrigerated by cryogenic liquid without source of electrical energy.
    BACKGROUND OF THE INVENTION
    Although no invention identical to that described has been found, we present below the documents found that reflect the state of the art related to the proposed invention. Thus, US Patent 2046953 A (KELLOGG JOHN L) of 07/07/1936, uses a cryogenic gas, not a cryogenic liquid as in the requested one, there being no metallic contact between the refrigerant container and the space to be cooled, while in the requested invention the system cools through the metallic junction ducts between the capsule and the inside of the container. In said patent compared to CO2 when it goes into a gaseous state, it is driven through sleeves into the barrels of drinks, mixed with the drinks and what it does is help to get the drink out under pressure and at the same time cools it. On the other hand, the requested invention has nothing to do with it, since what it does is to cool any food or beverage that is stored inside, through the metals that are connected to the cryogenic liquid containing capsule. Also in the comparative patent it is clearly explained that the system is part of the supply of carbonated beverages, in which it is used to expel with the aid of CO2 in gaseous state, the exit of the cooled beverage, because it is mixed with the beverage. There is a big difference between the two patents, in the requested one only two valves are used, an external housing, insulator and a capsule containing the pressurized liquid. The comparative presents instead some conduits for its operation that do not have to do with the conduits of union of the requested one and some sleeves to mix the gas with the drink. When in the system of the requested one the liquid only refrigerates, it is not mixed with the drink, nor is it mixed at any time with what is going to cool. It is only injected and returned to the atmosphere in gas, from the same compartment (the capsule).
    The document US 2104466 A (MARZOLF GEORGE B) of 04/01/1938, is very different from the requested invention, since this is to cool, keep refrigerated or even freeze, drinks and food, while the one compared instead is used for transport, and to dispense carbonated drinks. There is no other type of beverage to cool because if not, they would be carbonated when mixed with the liquid.
    US 1993730 A (CARPENTER WALTER E) of 03/12/1935, is a patent that uses dry ice, not a cryogenic liquid as in the requested invention. In addition, the insulator is totally different, with the metal outer shell, not like the one that is plastic. In addition, it needs a housing to cover the system together with the barrels, while the requested one cools through thermodynamics, (through the metallic joining ducts), and the one compared through insulated compartments and sleeves.
    Document ES2 008 998 14 refers to a cryogenic freezer for freezing food products or the like, which comprises: an insulated enclosure having a lower inlet and an upper outlet; conveyor means for moving food products along a path from said entrance to said exit, a greater part of said path being a helical section with a plurality of overlapping floors; means for contacting the food products, moving along said path, with liquid cryogen in a lower area generally near said inlet to initially extract a substantial amount of heat from the surface of said food products; means for producing a generally horizontal cryogen vapor circulation in all the upper zones of said helical section, whereby a vertical temperature gradient is created within said enclosure, with relatively warm temperatures existing near said outlet; and means for controlling the steam outlet by said inlet and said outlet so that at least about 80% of the cryogen vapor generated within said enclosure leaves it by said upper outlet.
    Document ES 2 106 976 T3 describes a refrigeration apparatus having at least a first and a second refrigeration compartment, each compartment having its own access door, comprising a first evaporator for said first compartment, said first evaporator working at a first pressure value; a second evaporator for said second compartment, said second evaporator operating at a pressure value greater than said first pressure level; a single capacitor; a single compressor; a refrigerant circuit comprising a series of conduits to provide a refrigerant flow sequentially to said first and second evaporators, said condenser and said compressor; valve means in said refrigerant circuit for directing refrigerant to a selected one of said evaporators from said condenser and to prevent a flow of refrigerant to said first evaporator when refrigerant is being directed to said second evaporator in order to cool said second compartment; a check valve in the duct on the suction side of said first evaporator, to prevent the return flow of refrigerant from said second evaporator to said first evaporator; and means in said refrigerant circuit for evacuating refrigerant from said first evaporator after finishing the refrigerant flow to said first evaporator in order to ensure that there is sufficient refrigerant charge for the sequential operation of the second evaporator.
    ES 2 289 552 T3 describes a cooling process of a product comprising N adsorption / desorption cycles ordered under vacuum of air, N being an integer greater than 1, each cycle comprising the steps consisting of: - extracting heat from a vapor phase refrigerant fluid in a condenser at a first pressure lower than the critical pressure of said fluid to condense said refrigerant fluid, - insert said liquid phase refrigerant fluid into an evaporator at a second pressure lower than the first pressure to vaporize a part of said refrigerant fluid and cooling the other part of said refrigerant fluid to a vaporization temperature of said refrigerant fluid at said second pressure, said vaporization temperature decreasing from one cycle to the next cycle, said first and second pressures being chosen at each cycle of so that said vaporization temperature in one cycle is every time lower than the temp Condensation time of said refrigerant fluid in the next cycle at the first pressure of said next cycle. - providing heat to the liquid part of said refrigerant fluid at said second pressure in said evaporator to evaporate said refrigerant fluid, - absorbing said vapor phase refrigerant fluid in at least one adsorption / desorption enclosure attached to said evaporator and containing an adsorbent of zeolite, - after an amount of said refrigerant fluid is adsorbed in said zeolite adsorbent, regenerate said zeolite adsorbent by heating to desorb said amount of refrigerant fluid in vapor phase, - forward said amount of refrigerant fluid in vapor phase towards said condenser, said process further comprising the following steps: effecting N-1 heat exchanges each time between the refrigerant fluid in the evaporator of one cycle and the refrigerant fluid in the condenser of the following cycle in the order of the cycles to thus perform said heat input in said evaporator and said heat extraction in said condenser, and Cool said product by heat exchange with the cooling fluid at least in the evaporator of the last cycle.
    Document ES 2 113 908 T3 refers to a domestic refrigerating apparatus with at least one refrigerating chamber that closes with a door, in which refrigerated product containers, a vaporizer and a fan that supplies it with ambient air are provided and which is located in the natural convection current produced by the cooling power of the vaporizer, characterized in that the fan necessarily exchanges the cooling air both during the cooling activity and during the defrosting activity, in which, by the location and formation of the Containers of refrigerated products and the fan, the refrigerant air is transported to the sector of the walls of the refrigerator space and along the door covering all the height and width of them.
    ES 2 296 668 T3 is an air cooling device, comprising a compressor having an inlet and an outlet, a turbo expander with a turbine wheel with which said compressor is connected to said turbo expander, a first fan mounted on a common shaft with the aforementioned turbo expander, a first dual duct heat exchanger, a cooling chamber with a second fan and an air cooler mounted inside the chamber, a second dual duct heat exchanger, a tank of water connected to a second conduit of the second heat exchanger, and a moisture separator; wherein a first duct of the second double duct heat exchanger, a first duct of the first dual duct heat exchanger, the moisture separator, the turbo expander, the air cooler, and the second duct of the first heat exchanger Dual duct, they are connected in series with the compressor inlet.
    Document ES 2 188 161 T3 refers to a domestic refrigerator cooled by the Peltier effect, with an enclosure to be cooled formed by one or two thermally insulated enclosures, where the air circulates by natural convection, in which the heat that enters the enclosures is removed by evaporation of a liquid in which at least one enclosure to be cooled is cooled by two units coupled in cascade, each unit comprising two thermosiphons separated by pellets of Peltier effect, one of which is arranged thermosipons of each unit for the condensation of a liquid housed inside it on a cold face of the pellets of Peltier effect and the other thermosiphon of each unit being arranged for the evaporation of a liquid housed inside it on a hot face of the granules Peltier effect, characterized in that each thermosiphon includes a first circuit for the circulation of evaporated liquid to an area in which the liquid it must be condensed, and a second circuit to return the condensed liquid to an area where it must evaporate, said second circuit not being the same as the first circuit. In one of the units coupled in cascade, the heat removal from the hot faces of the granules is arranged by the production of a fluid, which is caused to condense in an ambient air exchanger arranged in a raised position with respect to the granules, the condensed fluid being arranged to return by gravity. Thermosiphons contain water as a coolant with adequate degrees of vacuum, whereby evaporation occurs at the desired temperatures in each thermosiphon.
    Conclusions: As can be seen from the research carried out, we believe that none of the documents found affect the novelty and inventiveness of the compared invention, since none of these solves the problems posed as the proposed invention does.
