  • the embodiments described below relate to a heat store reservoir whereby the heat store may be used to heat a heat exchange liquid that may pass through the reservoir.
  • the reservoir is only able to store a quantity of heat energy. Once this quantity has been depleted, the heat energy in the reservoir may be replenished.
  • One way in which the heat energy may be replenished is by heating the heat exchange liquid and passing the heated heat exchange liquid through the reservoir so as to 'recharge' the heat store reservoir.
  • Each of the reservoirs described in the embodiments comprise a plurality of canisters, each filled with a phase change material.
  • the canisters are accommodated within the reservoir which is adapted to have a heat exchange medium, such as water, flow therethrough.
  • the water is in heat exchange relationship with the phase change material in the canisters, for reasons which will be discussed below.
  • the heated exchange medium is carried by a heat exchange circuit which is in heat exchange relationship with a heat source such as a solar collector or heat pump to heat the water.
  • the heat source may be provided external the reservoir (e.g. solar) or within the reservoir (e.g. heat coil located near the reservoir inlet).
  • the heat from the heat exchange medium is absorbed by the phase change material. With the absorption of sufficient heat the phase change material will melt into a liquid. Whilst in the liquid phase the phase change material stores both the sensible heat which has been applied to it as well as the latent heat. The reservoir then acts as a heat store, providing a convenient means to store the heat energy until heat is required.
  • the heat exchange medium is accommodated within another circuit which is in heat exchange relationship with a water reservoir.
  • the reservoir 11 defines a closed space and has an inlet 19 and an outlet 21.
  • the space defined by the reservoir is intended to receive a large number of sealed canisters 23.
  • Each canister is filled with a phase change medium such as sodium acetate tri- hydrate, which has a crystallisation temperature of the order of 58°C.
  • a phase change medium such as sodium acetate tri- hydrate, which has a crystallisation temperature of the order of 58°C.
  • the canisters are formed of an aluminium alloy which is substantially un-reactive to the heat exchange liquid within the reservoir and the phase change material.
  • Each canister is configured such that it will be able to withstand the pressures exerted upon it as a result of the temperature changes likely to occur within the reservoir and the phase changes of the material.
  • Each canister is of an identical form and has a cylindrical shape with a concave lower end wall 25 and cap 26 which is applied to the first end to sealingly close the canister.
  • each canister accommodates a diffuser means in the form of a thermally conductive element 41.
  • the purpose of the conductive element is to at least partially overcome the difficulties associated with the low coefficient of thermal conductivity of the phase change material, both in the liquid and solid phases.
  • the conductive element 41 is formed of aluminium and comprises a central tube 43 having a set of radially extending vanes 45 formed on its outer face. The diameter of the conductive element is such that it can be inserted into the first end of the open canister before the cap 26 is applied.
  • the conductive element is formed of aluminium.
  • the reservoir also comprises an inlet 19, which opens into the lower end of the reservoir, and an outlet 21 which opens into the upper end of the reservoir.
  • the canisters are accommodated within the reservoir in random manner as shown. Such an arrangement serves to induce a turbulent flow through the reservoir and maximise the exchange of heat between the heat exchange fluid and the canisters.
  • the second embodiment shown in figure 2 is similar to the first embodiment with the exception that in use the reservoir is not pressurised and an upper end of the reservoir can be removed to facilitate access to the canisters.
  • the canisters are accommodated within one or more bag-like enclosures which are formed of a mesh or net like material.
  • the use of such enclosures facilitates the introduction and possible later removal of the canisters into and from the reservoir.
  • the third embodiment of the invention is directed to a heat store which can be readily installed on site without the need of specialised lifting equipment and specialised personnel.
  • the third embodiment comprises a reservoir 11 which is of a generally cubic form having an upper end wall 13 and a lower end wall 15 and side walls 17, defining a space having a generally square cross section.
  • the upper end wall is removable to facilitate access into the interior of the reservoir and is associated with suitable fixing means and seals to enable it to close the reservoir to define a sealed space within the reservoir.
  • the upper portion of one side wall accommodates an inlet pipe 19 and an outlet pipe 21.
  • the inlet and outlet pipes are intended to be removably mounted into the side wall.
  • the space defined by the reservoir is intended to receive a large number of sealed canisters 23.
  • the upper end face of the closed canister defines an annular rib 27 which extends axially from the first end.
  • the outer end of the rib is formed with a radially outwardly directed flange 29.
  • the canisters are arranged in sets where each set is supported from a planar support element 31 which has a configuration generally complementary to the cross sectional shape of the reservoir.
  • the support element 31 is formed with a set of openings 33 which have a diameter corresponding or greater than the outer diameter of the flanges 29 on the canisters.
  • the inner edge of each opening is formed with a set of angularly spaced protrusions 35 which are resiliently deformable to permit the rib 27 of the canister to be pushed through the aperture. The protrusions then engage underneath the flange to resist disengagement of the canister from the support element 31.
  • the openings are arranged in an array to enable a number of canisters to be supported from the support element to depend there from in closely spaced relationship.
  • the support provided by the support element enables a space to be provided between the sides of the canister to enable the heat exchange liquid to readily flow between the canisters.
  • the openings of the support element 31 are not completely blocked. This facilitates the flow of the heat exchange liquid through the space and serves to restrict fluid flow past the support elements 31. This promotes thermal stratification between the sets of canisters during the heating phase, and minimises channelling of the flow of heat exchange fluid through the reservoir.
  • the depth of the space of the reservoir is sufficient to accommodate several sets of said canisters in a stacked arrangement as shown in Figures 3 and 4.
  • the inlet pipe 19 is formed with an inner axial extension 37 which extends from the upper end of the reservoir to the lower end. As best shown in figure 3 the extension 37 is received in aligned openings in the support elements which are not associated with canisters.
  • the lower end of the space supports a heater coil 39 to heat the incoming heat exchange medium when recharging the heat store.
  • the heating coil can be electrically powered or can comprise a heat pump or can be heated by a flow of heated fluid through the coil.
  • the canisters are formed of stainless steel and the heat exchange medium comprises potable water.
  • Each embodiment provides a heat store which (if required) can be readily installed on site without the need for specialised personnel or lifting equipment.
  • the third embodiment can be provided as a kit of parts comprising:
  • the canisters can be inserted into the support elements to form the sets of canisters. In so doing the corresponding opening of the support elements which is to receive the inlet pipe is left vacant.
  • the upper wall of the reservoir is removed and the sets of canisters are stacked into the reservoir with the vacant openings of the support elements aligned.
  • the inlet pipe is then installed by having its inner extension inserted into the vacant openings before being sealingly fixed to the side wall.
  • the outlet pipe is also sealingly fixed into the side wall.
  • the upper wall is then sealingly fixed to the upper end of the reservoir and the assembly is complete.
  • the reservoir, support elements and canisters can have any desired configuration.
  • the inlet and outlet can be fixed into position in the upper portion wall of the reservoir without the inner extensions of the first embodiment and the extensions can be located in position on site.
  • the inlet and outlet can be fixed into position in the wall of the reservoir at opposite ends to avoid the necessity to install them into the reservoir on site.
