Definitions

  • Heat stores are essentially designed as closed pressure-loadable containers, the heat being supplied and removed via an integrated coil system or via externally attached plate heat exchangers.
  • Cold stores in the temperature range around the freezing point of the water are essentially used as ice stores, the stores of which are open to the atmosphere, the loading and unloading taking place via coil heat exchangers which are embedded in the ice water. The ice forms outside the coils through which brine is led.
  • a relatively new ice storage method uses horizontally arranged tubes which are closed on both sides and in which the ice is formed and which are combined to form tube bundles.
  • This system is extremely reliable, also to build, install and control a few percentage points more efficiently, but with great effort.
  • the system requires horizontal containers, which means a lot of installation space.
  • An essential characteristic component of this invention is the exact vertical guidance of the energy-transporting medium from bottom to top or from top to bottom, completely evenly around the storage cartridges. Probiem on which the invention is based:
  • the solution according to the invention characteristically uses vertical, long storage cartridges (1, 1a) with a large exchange surface, which can be shaped in various ways as profiles in their cross section.
  • the profiles can be made of preferably metallic materials (1) or also of soft materials (1a), preferably plastics or types of rubber.
  • the longitudinally profiled storage cartridges (1, 1a) enclose a storage space and are open at both ends. They are sealed at one end by a stopper with tensioning screw connection (2), alternatively according to FIGS. 3 to 7, then inserted into storage containers (4-9), filled with the storage medium (22) and then at the upper end with the same or a similar one Plug technology closed.
  • the storage cartridges can be fixed in the container ready to be touched. If this is to be done exactly evenly, the plug screw connections according to FIGS. 3 to 7 are extended so that they can be inserted into previously made locking openings in the lower container base (5) or in the distribution and carrying base (12). This also ensures an absolutely uniform distribution of the medium flowing through the storage heat exchanger along the heat exchanger surfaces of the storage cassettes.
  • FIG. 1 Representation of the characteristic storage heat exchanger in longitudinal section with container (4,5,6,7), exemplified with 9 storage cassette profiles (1) as pipes, which are closed on their upper and lower sides by a screw plug and with their outer wall (heat exchange surface ) act as individual self-sufficient heat exchangers.
  • the clamping screws (18, 19) are extended so far that they also serve as spacers at the upper and lower ends of the container (4, 5, 6, 7), creating free spaces in the container, which in turn serve as distribution chambers for the medium flowing through (usually brine or water / glycol).
  • the medium supply (8) and drain connection (9) are attached at the level of these distribution rooms.
  • the container is double-walled (4,4a) and thus the medium supply (8) and outlet connections (9) are attached to the upper container cover.
  • a feed pipe (10) which is installed instead of a storage cassette (1), brings the heat or coolant medium from the inlet flange (8) to the lower container collection chamber, which allows the heat or coolant medium to flow upwards around the heat exchanger surfaces of the storage cassettes.
  • the medium flows through a distributor plate (12), which is designed with a large number of openings (13), which force an even distribution to all storage cartridges (1).
  • This distributor plate (12) is also designed as a support plate so that the storage cartridges are inserted into it at precisely specified intervals, and are also attached and carried as required. As a variant, this distributor plate (12) can also be attached to the top of the cassette. This creates a complete heat exchanger and storage block according to FIG. 6.
  • FIG. 3 Figure 3 - representation of the cassette closure at the two storage and heat exchanger cassette ends.
  • FIG. 5 Representation of the cassette lock, the sealing plug (14) used in a variant of Figure 3 now being given a shape which is optimized according to the respective installation conditions (20).
  • FIG 6 representation of the cassette closure, the cassette (1a) being made of soft material in a variant of Figure 3 and the sealing pressure is intercepted by a ring (24).
  • FIG. 7 Representation of the cassette lock, in which variant the sealing plug (14a) consists of solid material and the sealing pressure is generated by a pipe clamp (25).
  • Storage cartridges are at least partially screwed (21) at their upper and lower ends by means of the extended sealing screws (18, 19) to the distributor and support plates (12), so that a structurally coherent block is formed which outside the containers (4, 5, 6,7) and only then is it installed in the container.
  • the illustration shows the storage cartridges (1) filled with a storage medium (22). Profiles (23) are attached to the screw clamps (18) in the storage space, which prevent the ice from floating in the event of a discharge as an ice storage version.

Abstract

Selon la présente invention, l'accumulateur de chaleur ou de froid est conçu simultanément en tant qu'échangeur thermique, caractérisé en ce que les parois d'accumulation (1) représentent simultanément les parois de transfert de chaleur ou de froid. Ledit accumulateur est composé d'un paquet de plusieurs accumulateurs (1) de très petite taille, placés de préférence verticalement dans un réservoir (3) sous forme de cassettes ou profilés verticaux à grandes surfaces de paroi. Ces accumulateurs sont scellés au niveau de leurs extrémités lors du montage par des bouchons (2) sous l'effet d'une pression d'appui dosable contre la pression intérieure ou extérieure, ces éléments de scellement agissant à des emplacements précisément spécifiés à la fois comme élément d'écartement et comme élément de fixation. Ces éléments de scellement sont caractérisés en ce que, par rapport à l'état actuel de la technique, des chambres de répartition coûteuses pour le fluide entrant (4) et sortant (5), traversant l'échangeur thermique accumulateur, sont supprimées. Ainsi, les cassettes (3) peuvent être placées de façon très proche les unes des autres, ce qui permet d'augmenter de façon correspondante la capacité d'accumulation et la puissance tout en diminuant le volume de remplissage du fluide de transfert d'énergie. Les cassettes d'accumulation (1) et le paquet d'accumulateurs sont également conçus, de sorte que des changements d'état solide / liquide du fluide accumulateur peuvent être exécutés sans problème dans ces derniers.
