Definitions
- This invention relates to a water heater/cooler, and relates particularly, though not exclusively, to a solar boosted heat pump water heater and method of manufacture thereof.
- a tin/lead/flux-acid solder paste is applied to the tube during its attachment to the water tank and the water tank is subsequently heated in an oven to melt the solder to complete the heat transfer bond between the tube and the water tank.
- the prewinding processes involving the grinding of the outer cylindrical surface to remove scale; a priming wash and a final wash with a copper sulphate solution to aid tinning and maintaining the tube under tension slows the manufacturing cycle and the post heating of the complete water tank to melt the solder results in further production time losses.
- the gas required to heat the tank mass to solder fusion temperature and the resultant cooling time adds considerable expense and time to the manufacturing process.
- the manufacturing process has the tube deforming/tensioning device about 600 mm from the tank when the tube is being applied which allows the tube to be randomly twisted as it leaves the rollers and may lead to loss of contact between the water tank and the tube. It is therefore an object of the present invention to provide a water heater that improves on the concepts described in Australian Patent Nos. 582,291 and 603,510.
- a further object of the present invention is to provide a water heater that is simpler to construct than that described in Australian Patent Nos. 582,291 and 603,510.'
- a water heater/cooler including a water tank having a wall formed from material having heat transfer properties, a tube adapted to carry, in use, a refrigerant fluid, is applied externally about said tank wall, a heat-conductive material is coextensive with the length of said tube to allow said tube to be in said in heat- conductive contact with said tank wall and at least one layer of material tightly wrapped about said tank wall and said tube.
- said tube is compressed against said tank wall and said compression is maintained by said at least one layer of material.
- said tube is of circular cross-section and during compression against said tank wall is deformed into a D-shape in cross-section.
- said tube is of circular cross-section and during compression against said tank wall is deformed into a bi-lobular profile.
- said at least one layer of material includes at least one layer of stretch wrap film and at least one layer of a heat reflective material thereover.
- at least a further layer of stretch wrap film is applied over said at least one layer of heat reflective material.
- said stretch wrap film is polythene based.
- said heat conductive material is a non-setting heat conductive paste.
- said at least one layer of stretch wrap film surrounds said heat conductive material in an airtight manner.
- said tube extends over at least 85% of the length of said tank.
- a method of forming a water heater/cooler including the steps of winding a tube around the wall of a water tank under which a heat-conductive material coextensive with the length of said tube has been applied to either said tube or said wall of said water tank to allow said tube to be in heat-conductive contact with said tank wall and tightly wrapping at least one layer of material about said tank wall and said tube.
- beads of heat-conductive material are applied to said tank wall on either side of said tube and said beads are formed into a join fillet to, in use, increase the heat transfer of said tube with said tank wall.
- FIG. 1 is a perspective view of water heater made in accordance with a preferred embodiment of the invention
- Fig. 2 is a cross-sectional view of the water heater shown by the area circled "2" in Fig. 1;
- Fig. 3 is an enlarged view shown by the area circled "3" in Fig. 2;
- Fig. 4 is a sequence of steps to apply the tube to the water tank to make the water heater shown in Fig. 1 ;
- Fig. 5 is a variation of the profile shown in Fig. 3 without the wrappings.
- a water heater 10 including a water tank 12 having a bottom wall 14, typically concave or convex, a convex top wall 16 and a cylindrical sidewall 18.
- Water tank 12 can be formed of any suitable thermal conductive or heat transfer material preferably metallic or alloy based. In the preferred embodiment the water tank is formed from glass lined steel, stainless steel, copper or other suitable material.
- a cold water inlet (not shown) will be installed adjacent bottom wall 14 and a hot water outlet (not shown) will be installed adjacent the top wall 16.
- the water tank 12 is held in a cylindrical casing 20 sealed by lid 22. Insulating foam (not shown) will fill the gaps between water tank 12 and cylindrical casing 20 and lid 22.
- Tube 24 is wrapped about cylindrical sidewall 18 and has an inlet 26 and outlet 28.
- Tube 24 is also formed of any suitable thermal conductive or heat transfer material preferably metallic or alloy based.
- tube 24 is formed from copper in view of its pliability and corrosion resistance. Tube 24 will typically extend over 85% of the length of cylindrical sidewall 18.
- Refrigerant typically R22 and including R12 equivalents, is pumped through tube 24 to heat the cylindrical sidewall 18 and thus heat the water contained within water tank 12.
- Tube 24 is part of a solar boosted heat pump water heating system, which is described in Australian Patent Nos. 582,291 and 603,510. In order to avoid duplication of description reference is made to Australian Patent Nos. 582,291 and 603,510, the contents of which are herein incorporated into this specification.
- Tube 24 has a D-shape (as shown), oval shape or other closed shape with a flattened base 30 and is formed by deforming a circular cross-sectional tube prior to its application to, or by form roller compression as shown), against the cylindrical sidewall 18.
- Tube 24 has a heat transfer paste 32 applied to the base 30 to maximise the heat transfer from tube 24 to cylindrical sidewall 18.
- Tube 24 is applied under compression to cylindrical sidewall 18 and layers of material wrapped around water heater 10 to maintain the compression.
- two layers 34, 36 of a stretch wrap film are applied first.
- the stretch wrap film may be a polythene film of a suitable formulation.
- the next layer 38 is an aluminium foil and it will act as a reflector to turn back heat to water heater 10.
- layer 38 is encased in a further four (4) layers 40,42,44,46 of stretch wrap film.
- the number, and interleaving of the layers of material can be varied to suit requirements and are not restricted to the number and positioning of layers described.
- the wrapping and compression of the layers will ensure the integrity of the heat transfer paste 32 and will seal the paste against the possibility of air or heat cycle drying. Without the wrapping, the heat transfer paste 32 would tend to dry out and become crumbly when exposed to air over time. The heat cycling would also hasten this disintegration. The crumbling would reduce the heat conductive contact between tubing 25 and sidewall 18.
- the wrapping seals the paste 48 from air and avoids any drying or thickening effects.
- Fig. 4 shows the sequential steps of applying tube 24 to cylindrical sidewall 18.
- tube 24 is formed by roller compression.
- a length of circular cross-sectional tubing 25, for example of 10 ram diameter is moved into position and held against cylindrical sidewall 18.
- a bead, for example of 3 mm diameter, of heat transfer paste 48 is placed on the horizontally rotating water tank 12 from a dispenser (not shown) underneath where tubing 25 will be forced onto the cylindrical sidewall 18.
- the heat transfer paste 48 used in this embodiment is known as Bostik heat transfer sealer #1128 or #5603.
- the heat transfer paste 48 in this embodiment is a grease-like material with no bonding properties but a bonding type material may also be used.
- tubing 25 is compressed to a D-shape (as shown) or an oval shape against cylindrical sidewall 18 to flatten the bead of heat transfer paste 48 and allow a uniform thickness of paste to be applied to base 30 of tube 24. Paste 48 will typically ooze out from underneath base 30.
- Tubing 25 is deformed into the D-shaped or oval tube 24 by a compression roller 64 which rotates about axle 66 to compress and deform tubing 25 onto cylindrical sidewall 18.
- a pair of parallel beads 50,52, for example of 4 to 6 mm diameter, of heat transfer paste are applied to cylindrical sidewall 18 and opposing sides of tube 24. This step will increase the size of the heat transfer footprint.
- Tube 24 is typically wound from the bottom to the top and is held, but not attached, to cylindrical sidewall 18 at both ends by a bracket (not shown), typically plastic, which clips onto tube 24.
- the clips are held to cylindrical sidewall 18 by a non-stretch binding passing around the tank circumference and pulled tight.
- the windings of tube 24 are usually in a tighter spiral at the lower half 58 than at the upper half 60.
- windings may be used, for example, a progressive spiral increase with a variable pitch, two separate winding, one above the other or interleaved.
- layers 34-46 are then applied as discussed with reference to Figs. 2 and 3. Tube 24 is then bent across the wrapped windings to provide outlet 28.
- Fig. 5 shows a variation of the D-shaped profile of tube 24.
- tube 24 is indented at 68 to provide a bi-lobular profile with lobes 70, 72. This will increase the concentration of heat mass to the edges of tube 24 and into the paste fillets 56 to increase the refrigerant velocity in the areas of the tube where refrigerant oil accumulates to assist oil return and reliability.
- the preferred embodiment discussed above simplifies construction of a water heater compared to the techniques disclosed in Australian Patent Nos. 582,291 and 603,510.
- the preferred embodiment shows a 28% increase in performance over the water heater shown in Australian Patent Nos. 582,291 and 603,510 and a reduction in the compressor/water temperature ratio of over 10 % in the mid to high temperature range.
- These performance improvements will directly increase efficiency and compressor life and reduce noise output.
- the preferred embodiment had at least a 28% higher Coefficient of Performance. This value increased to a 38% increase when 24 hour heat losses and their subsequent recovery were taken into account.
- water tank 12 could hold cooled water by reverse cycle refrigeration where the refrigerant in tube 24 is cold rather than hot.
