Definitions

  • the present invention relates to a solar collector with a phase change heat storage material.
  • Solar collectors are devices used for absorbing solar radiation (i.e. sunlight) and converting the energy therein into a more useful form.
  • Thermal solar collectors are designed to collect heat by absorbing sunlight, and may be concentrating, with a reflector arranged to direct sunlight onto a smaller absorber, or non-concentrating, in which the absorber absorbs directly incident sunlight.
  • Concentrating solar collectors are more complex, and are generally used in the context of large scale electricity conversion, in which heat from the solar collector is used to generate electrical power.
  • Non-concentrating solar collectors are typically used to heat water, for example for domestic use.
  • Existing systems typically employ a fluid circuit to remove heat from the absorber and reject the heat into a container in a different location which holds the water to be heated.
  • the water container may for instance be located within a building, with the solar collector being on the roof of the same building. Considerable heat may be lost from the fluid circuit that connects the water container with the solar collector.
  • the water container may be arranged so that hot water is taken from the top of the container with new cold water being introduced at the bottom of the container, and so that the fluid in the fluid circuit flows generally downwards through the container.
  • the temperature of the water in the container will thereby naturally stratify, with relatively hot water at the top of the tank.
  • hot water drawn from the hot water container is at a temperature of at approximately 70°C or more.
  • the water from the hot water container may be mixed with cooler water to provide an appropriate temperature.
  • the temperature of the hot water available from the hot water tank is below 70°C, for instance being in the range of 40°C to 45°C. Even though this temperature is higher than that of the cold water in the system, it may not be possible to use the hot water due to the risk of Legionella bacteria (which multiply at temperatures below approximately 45°C). This results in a waste of heat, contributing to a lack of efficiency in solar water heating.
  • phase change materials are used to store heat (Atul Sharma et al, Review on thermal energy storage with phase change materials and applications, Renewable and Sustainable Energy Reviews 13 (2009), 318-345). Although various approaches have been proposed for the use of phase change materials in solar collectors, none of these approaches has been sufficiently effective to be commercially adopted.
  • a solar collector comprising a solar absorber for absorbing solar radiation and converting it to heat.
  • the solar absorber has a solar radiation receiving surface and a corresponding substantially parallel back surface.
  • a heat storage section is disposed adjacent the back surface and has a heat storage medium for storing the heat from the solar absorber.
  • a first fluid circuit is arranged to transport heat from the solar absorber to the heat storage section, and a second fluid circuit is arranged to transport heat from the heat storage section as a heat output from the solar collector.
  • the heat storage medium comprises a phase change material.
  • the absorber, heat storage section, and first and second fluid circuits are arranged as or within a self-contained unit.
  • the phase change material may have a phase change at a predetermined temperature selected to correspond with a required heat output temperature from the solar collector.
  • the phase change may preferably be at a temperature between 60°C and 100°C. More preferably the phase change may be at approximately 70°C.
  • the solar absorber may comprise a flat plate absorber or evacuated tube absorber.
  • the solar collector may further comprise a reflector, with a larger area than the solar absorber, arranged to concentrate solar radiation on the absorber.
  • the solar collector may be substantially cuboidal.
  • the solar collector may comprise an enclosure in or around which the absorber, heat storage section, and first and second fluid circuits are arranged as a self-contained unit.
  • Thermal insulation may be provided around at least part of the heat storage section.
  • the thermal insulation around the heat storage section preferably also insulates at least part of the back surface of the solar absorber and/or at least part of the first fluid circuit.
  • the first and/or second fluid circuit may be thermally connected to fins which increase the surface area for heat absorption and/or rejection.
  • the fins may improve thermal contact between the first and/or second fluid circuit and the heat storage medium.
  • Each of the fins may be substantially parallel.
  • the fins of the first and second fluid circuit may be interleaved.
  • the first and/or second fluid circuit is preferably arranged along a serpentine path through the heat storage section. More preferably, the first fluid circuit is arranged along a serpentine path through the heat storage section, and the second fluid circuit is arranged along a corresponding, adjacent serpentine path through the heat storage section.
  • the first fluid circuit may be arranged to use thermo-siphoning to circulate a fluid therein.
  • heat from the solar absorber that is absorbed into the fluid causes the fluid to rise, thereby driving circulation of fluid along the first fluid circuit.
  • the second fluid circuit may be arranged to use thermo-siphoning to circulate a fluid therein.
  • heat from the heat storage section that is absorbed into the fluid causes the fluid to rise, thereby driving circulation of fluid along the second fluid circuit.
  • the first and second fluid circuit may be arranged so that, in use, fluid circulates in substantially opposite directions in the first and second fluid circuit through the heat storage section.
  • the first fluid circuit may be arranged along a closed path from the solar absorber to the heat storage section and back to the solar absorber.
  • the heat storage section may comprise a plurality of heat storage modules, each module comprising a first module fluid channel and a second module fluid channel and containing a phase change material.
  • the first fluid channel may comprise a series connection of the first module fluid channels and the second fluid channel may comprise a series connection of the second module fluid channels.
  • the first fluid circuit may comprise a condenser.
  • the heat storage section is described above as having a heat storage medium for storing the heat from the solar absorber. It will be appreciated that the heat storage medium need not be included within the heat storage section when the solar collector is made and sold, but could e.g. be put in at the time of installing the solar collector. The heat storage section therefore need merely to be suitable for holding a heat storage medium for storing the heat from the solar absorber in use.
  • a method of using the solar collector of the first aspect wherein the second fluid circuit is used to provide, on demand, a fluid heated to a predefined temperature corresponding to a phase change temperature of the phase change material.
  • FIG. 1 is a schematic of a solar collector according to an embodiment of the invention.
  • FIGS. 2 to 4 are schematic diagrams showing details of a heat storage module of the solar collector of Figure 1 ;
  • FIG 5 illustrates the fluid path of the heat storage section of the solar collector
  • Figure 6 is a rendering of a solar collector according to an embodiment of the invention.
  • a solar collector 100 according to an embodiment of the invention is shown, comprising: solar absorber 1 , enclosure 3 with glass cover plate 2, heat storage section 4, insulation 5, first fluid circuit 6, second fluid circuit 7, and condenser 8.
  • the solar collector 100 is designed to be used at an angle (as shown in Figure 1 ). Using the solar collector 100 in a similar orientation to that shown tends to maximise the power of the incident solar radiation on the solar absorber 1 , and facilitates thermo- siphoning as will be explained in more detail below.
  • the exterior of the solar collector 100 is substantially box shaped, having a box shaped enclosure 3 with an opening in one face, the glass cover plate 2 extending over the opening.
  • the solar absorber 1 comprises a substantially flat rectangular absorber plate, comprising metal.
  • the solar absorber 1 is coated on a solar radiation receiving side with a material having a high absorptivity for sunlight.
  • the solar absorber thereby converts the energy of solar radiation incident on the absorber plate into heat within the plate.
  • the solar absorber 1 is mounted within the enclosure 3 adjacent to the glass cover plate 2, which provides a robust easily cleaned exterior to the collector 100, while at the same time allowing sunlight to illuminate the absorber 1 .
  • the first fluid circuit 6 is in thermal contact with the solar absorber 1 and a heat storage medium 17 of the heat storage section 4, and thereby heat from the solar absorber 1 is accepted into a working fluid of the first fluid circuit 6, transported, and rejected into the heat storage medium 17.
  • the second fluid circuit 6 has an input 32 and output 31 for the fluid to be heated by the solar collector 100, and is in thermal contact with the heat storage medium 17. The fluid to be heated thereby accepts heat from the heat storage medium 17.
  • the second fluid circuit 7 forms an open circuit within the solar collector 100, and forms part of a closed circuit in use when connected to the external system.
  • the first fluid circuit 6 forms a closed circuit within the solar collector 100.
  • the working fluid of the first fluid circuit 6 may be any suitable fluid, and in some embodiments may conveniently comprise water.
  • the working fluid of the first circuit may further comprise a corrosion inhibiting material.
  • the metal of the absorber plate has a relatively high thermal conductivity, ensuring that heat is effectively transported to the first fluid circuit 6.
  • the first and second fluid circuits 6, 7 preferably comprise metal conduits that similarly provide good heat transport into the working fluid therein.
  • the fluid to be heated may be water, for example for domestic hot water supply. As will be explained below, this embodiment is suitable for use in heating water to a predefined temperature on demand.
  • the first fluid circuit 6 comprises a plurality of parallel tubes, each in thermal contact with the solar absorber 1 , connected in parallel at a first end to a first substantially perpendicular tube adjacent an upper edge of the solar absorber 1 , and at a second end to a second substantially perpendicular tube adjacent a lower edge of the solar absorber 1. Heating of the working fluid within the first fluid circuit 6 thereby tends to drive convection in an upward direction through the portion of the first fluid circuit 6 which is in thermal contact with the solar absorber 1. This thermally driven convection drives a thermo-siphon which circulates the working fluid of the closed first fluid circuit 6.
  • the first fluid circuit 6 transports the heated working fluid from the solar absorber 1 , through insulation 5, to the condenser 8 which transfers the heat of condensation of a working fluid vapour into the heat storage section 4.
  • the condenser 8 is located within the heat storage section 4 to improve heat transfer thereto.
  • Working fluid exiting the condenser 8 is in the form of a liquid.
  • condensation of a working fluid of the evacuated tubes may be the primary method of rejecting heat from the solar absorber 1.
  • the first fluid channel 6 may therefore be arranged to accept heat from a condenser 8 which condenses a working fluid of the solar absorber 1 .
  • the first fluid circuit 6 transports fluid from the condenser 8 to the heat storage section 4.
  • the heat storage section 4 and condenser 8 are surrounded by insulation 5 to minimise heat loss therefrom.
  • Each of the elements of the solar collector 100 is contained within the same enclosure 3 as the solar absorber 1 . It will be understood that in some embodiments, elements of the solar collector may be attached to the exterior of the enclosure 3, for example the solar absorber 1 .
  • the solar collector 100 thereby forms a self-contained unit.
  • the heat storage section 4 is disposed adjacent to a back surface of the solar absorber 1 , the back surface being parallel with and adjacent to the sunlight receiving front face of the absorber 1 . It will be appreciated that the insulation 5 between the heat storage section 4 and the solar absorber 1 may thereby insulate both the heat storage section 4 and the back side of the absorber 1.
  • the heat storage section 4 comprises a plurality of heat storage modules 10, which are more clearly shown in Figures 2 to 4.
  • Each heat storage module 10 has a box shaped enclosure 18, within which is contained a heat storage medium 17 comprising a phase change material.
  • Fluid inputs and outputs 13, 14 are provided extending from one face of the module enclosure 18 for a first module fluid circuit and second module fluid circuit 1 1 , 12 respectively.
  • the first and second module fluid circuits 1 1 , 12 pass through the module enclosure 18, in contact with the heat storage medium 17.
  • the first and second module fluid circuits 1 1 , 12 are adjacent within the module enclosure 18, and describe a U-shaped path therein, extending from the module enclosure face having inputs and outputs 13, 14 over substantially the full length of the interior of the module enclosure 18.
  • both the first and second module fluid circuit 1 1 , 12 are provided with respective fins 16, 15 that increase their effective surface area in contact with the heat storage medium 17.
  • the fins 16, 15 are substantially flat and parallel, and are longitudinal to the straight portions of the U-shaped fluid circuits 1 1 , 12.
  • the fins 16, 15 extend between the internal faces of the module enclosure 18, and are also parallel with a face thereof, effectively partitioning the interior of the module enclosure into a series of parallel slices.
  • Heat transport members (not shown) are preferably provided between adjacent fins 16, 15 to transport heat perpendicular to the plane of the fins 16, 15. These fins 16, 15 also act to increase the rigidity and robustness of the structure, and serve to tie the two fluid circuits 1 1 , 12 together.
  • the heat storage section 4 of the solar collector 100 in this embodiment comprises five heat storage modules 10, and the first and second fluid circuits 6, 7 comprise the first and second module fluid circuits 1 1 , 12 of the modules connected together in series.
  • the heat storage modules 10 are arranged adjacent to each other and their respective fluid inputs and outputs 13, 14 are connected together by connecting portions 22 so that the U-shaped module fluid circuits 1 1 , 12 together define serpentine paths 21 through the heat storage section 4.
  • the serpentine paths 21 increase the surface area presented to the heat storage medium material, and increase transition time through the heat storage section for a given flow rate.
  • the serpentine paths of the first and second fluid circuits 6, 7 are adjacent, and correspond with each other.
  • the thermal siphoning effect within the first fluid circuit 6 is further enhanced by arranging for the working fluid of the first fluid circuit 6 to pass downwards through the heat storage section 4 as it cools.
  • the second fluid circuit 7 is arranged to pass the fluid through the heat storage section in an upward direction as it is heated, thereby setting up a further thermally driven flow in this circuit.
  • this thermally driven flow in the second fluid circuit is particularly advantageous because it enables the solar collector 100 to be effective without the need to incorporate any electrical or mechanical elements.
  • the flow through the first and/or second fluid circuit may be externally driven, for example by a pump (not shown).
  • the phase change material of the heat storage medium 17 preferably has a phase change temperature corresponding with a desired heat output temperature from the solar collector 100, for example between 60°C and 100°C. More preferably the phase change temperature is approximately 70°C.
  • the phase change is preferably between a liquid and solid state, and is preferably associated with a large change in enthalpy so that a minimum volume of heat storage medium is necessary to store a large amount of heat.
  • the phase change material may comprise an alkane or iso-alkane, for example a paraffin wax.
  • the phase change material may be loaded with a thermally conducting substance to improve its thermal conductivity.
  • the phase change material may be heated to its melting point by the working fluid of the first fluid circuit 6.
  • the input of further heat to the phase change material will result in melting of the phase change material, which typically requires a substantial amount of energy. Assuming the phase change material is in thermal equilibrium, until the phase change material has completely melted its temperature will not rise above the melting point. Similarly, absorbing heat from molten phase change material into the fluid of the second fluid circuit will not reduce the temperature of the phase change material until all of the material has solidified.
  • the example embodiment therefore allows the fluid in the second channel to be heated to a substantially constant temperature which corresponds with the phase change temperature of the phase change material.
  • the solar collector therefore can be used to supply hot water for domestic use, on-demand, in a similar manner to continuous water heaters employing electrically powered heating or gas burners.
  • the relatively low thermal conductivity of many phase change materials, combined with the lack of convective heat transport in the solid phase means that it is important to minimise the thermal diffusion distances through the phase change material, so as to more closely approximate a system in thermal equilibrium during heat flow.
  • the fins of the present invention are directed towards this objective.
  • a solar collector arranged to heat water to approximately 70°C may be used to supply hot water which is free from Legionella, for mixing with cooler water in a thermostatic mixer valve to an appropriate temperature.
  • the tubes defining the first and second fluid circuits are preferably copper, which has a high thermal conductivity, and proven longevity.
  • any suitable material may be used, for example aluminium.
  • the solar collector 100 may also be provided with a backup heat source that is operable to be switched in when the heat stored within the heat storage section 4 has been fully discharged, or to provide a boost when desired.
  • a backup heat source that is operable to be switched in when the heat stored within the heat storage section 4 has been fully discharged, or to provide a boost when desired.
  • This may be provided in the form of an electric heater, which may conveniently be arranged to heat the fluid in the second fluid circuit 7 on demand.
  • an electric heater may be arranged in thermal contact around the conduits of the second fluid circuit 7.
  • FIG. 5 a rendering of a solar collector 100 is shown.
  • the fluid inputs 32 and output 31 of the second fluid circuit are visible.
  • the fluid inputs and outputs 32, 31 are both provided adjacent to an upper edge of the solar collector 100.
  • Integrating a heat storage section with a heat absorber allows a very compact system, and solves the problem of heat loss in interconnections, sometimes lengthy, between the heat storage and the solar absorber.
  • the accumulation of heat in the energy associated with a phase change minimises the necessary amount of heat storage medium, and allows the output of heat at a constant temperature, thereby enabling on- demand domestic water heating without the need for complex control mechanisms.
  • the circulation of heat takes place entirely naturally, by thermo- siphoning, without the need for any electrical or mechanical elements that may be prone to failure; this contributes to a robust and long-lasting product.
  • the present invention further allows more efficient use of solar energy, reducing the necessary area of a solar installation. In view of its light, compact and self-contained design, it is easily portable.
  • the use of a fluid circuit to deliver heat from the solar absorber 1 to the heat storage section 4 has advantages over an alternative arrangement having a heat storage section heated directly by the solar radiation.
  • An arrangement according to an embodiment of the present invention, with two fluid circuits, allows the heat storage section 4 to be completely surrounded by insulation on all sides, so that the system is able to preserve stored energy very effectively; this allows operation at very low temperatures, for example down to -30°C.
  • a directly-heated heat storage one side would be required to be free of insulation to allow the solar radiation to reach the heat storage.
  • the use of a separate fluid circuit also allows the captured heat to be delivered very efficiently throughout and deep within the phase change material in the heat storage section 4, for example along a winding, circuitous or serpentine path. With a directly-heated heat storage, only the surface layer of the material would be heated effectively.
