Definitions

  • the cooling system has at least one cooling machine, which is designed to cool the coolant and is coupled to the line system of the cooling system.
  • Cold storage are known from the prior art, which are designed for example as an ice storage.
  • the coolant is passed through the ice storage via a line arrangement.
  • the coolant which has been cooled by a refrigerator, is guided in a first direction through the ice storage and fed to a cooling device with a consumer. Subsequently, the coolant is supplied from the consumer back to the chiller, wherein the process is repeated.
  • the coolant can be passed through a further line arrangement opposite through the ice storage, wherein the further line arrangement is arranged so that it leads over the consumer heated coolant through the ice storage.
  • the ice contained in the ice storage absorbs the heat contained in the refrigerant, so that the refrigerant is cooled and can be supplied to the consumer again.
  • the known from the prior art ice storage are designed so that an optimal regeneration of the ice storage occurs. Accordingly, the line assemblies within the ice storage are arranged so that the coolant flows through the ice storage vertically.
  • the coolant Since set in the ice storage certain temperature layers, but no optimal cooling of the coolant can be achieved. Especially with vertically extending line arrangements, the coolant passes through different temperature layers within the ice storage.
  • the arrangement of the second line arrangement makes it possible that the coolant is not passed over a plurality of temperature layers within the cold storage, but is guided only substantially within a range having a certain temperature or a certain temperature range. Due to the vertical arrangement of the first line arrangement can be carried out on these a loading and regeneration of the cold storage, as known from the prior art.
  • the horizontal arrangement of the second conduit arrangement makes it possible to guide a heated coolant within the range of the fluid, which has, for example, 0 degrees Celsius.
  • the guided in the second conduit arrangement coolant is not passed through other temperature ranges of the fluid and can thereby assume substantially the temperature of the area in which the second conduit arrangement extends.
  • the second line arrangement may be arranged in further embodiments in an upper region of the storage space.
  • a certain temperature arises in the upper region of the cold accumulator, for example an ice accumulator. This temperature is maintained over a wide operating range of the cold accumulator, regardless of whether or not ice has formed within the cold accumulator. This makes it possible to cool the coolant at a certain temperature even when the cold storage is not or not fully loaded. Because the second line arrangement is arranged in the upper region of the storage space, the coolant does not have to be conducted over a plurality of temperature ranges within the storage space.
  • the cold storage may have a third line arrangement which is arranged in the storage space, wherein the third line arrangement is arranged such that coolant passed through the third line arrangement flows through the cold store vertically and opposite to the flow direction of the coolant guided in the first line arrangement.
  • the third line arrangement By means of the third line arrangement, a further cooling of the coolant can be achieved, whereby a targeted defrosting is possible analogously to the ice stores known from the prior art.
  • the cold storage may also have a plurality of mutually parallel second line arrangements in other embodiments.
  • the conduit arrangements can be arranged at different distances from each other within the storage space, so that the coolant can be cooled at different temperatures.
  • the area in which is arranged a first line arrangement of the second line arrangements is a temperature between 0 and 3 degrees Celsius.
  • a second line arrangement of the second line arrangements can be arranged, for example, in a temperature range between 3 and 4 degrees Celsius and a third line arrangement of the second line arrangements can be arranged in a temperature range between 4 and 5 degrees Celsius.
  • the second line arrangements can be connected via valves or other coupling devices to a flow of a cooling system.
  • both the first line arrangement and the at least one second line arrangement have in their respective flow sections a speed-controlled pump which regulates the coolant flow in the respective line arrangements.
  • a speed-controlled pump can also be arranged in the third line arrangement.
  • the first line arrangement, the second line arrangement and / or the third line arrangement may have at least one heat exchanger and / or helically extending line sections.
  • the heat exchangers and / or helical line sections provide a large transition surface for heat transfer between the fluid stored in the cold accumulator and the coolant. As a result, the cooling of the coolant can be further improved. In addition, it is possible to load the cold storage faster.
  • the fluid received in the storage space may in other embodiments be water.
  • a brine for example, a water-glycol mixture may also be performed in the line sections.
  • defined temperature ranges are often established.
  • the water in the bottom area of the cold storage at a temperature of 4 degrees Celsius, since at this temperature, the water has its highest density. In the upper area, the water usually has 0 degrees Celsius. If, in a conventional embodiment of the cold accumulator, cooling of the coolant would then be carried out via vertically extending line arrangements, it would be almost impossible-depending on the return temperature of the coolant-to bring the sols carried in the lines to 0 degrees Celsius.
  • the coolant is also guided through areas within the cold accumulator, which are warmer than 0 degrees Celsius.
  • the coolant may However, be brought selectively to a temperature of 0 degrees Celsius, since the coolant is passed through the second line arrangement, for example, only in the upper region within the cold storage.
