In general heat pumps are classified based on where they source their heat. For example ground source heat pumps get their heat from the ground and air source heat pumps get their heat from the air. Air to water heat pumps currently available in the market make use of a single unit which is typically located outdoors. The heat pump has an evaporator within their outdoor unit and there is a fan that forces the air through the evaporator to absorb the heat. There is also a condenser to transfer heat to the heating medium which in most cases is a water/glycol mix.

  • the compressor and or the single unit may be mounted in such a way as to absorb or minimise vibration and or to minimise noise.
  • a heat pump is a device which transfers heat from a source of low temperature energy to a region of high temperature, by doing work, and this is the principle behind the operation of the refrigerator.
  • the working fluid (ore refrigerant) is, at one stage in the process, a vapour; a vapour being a gas at a temperature which is below its critical temperature, so that it can be converted to a liquid by the application of pressure alone.
  • This vapour is compressed by means of a compressor pump and, provided that the accompanying change is adiabatic; and thus takes place without heat entering or leaving the system; the temperature of the vapour rises, due to work being done on it by the compressor. It is then passed to a radiator, where heat is given out to the surroundings when the vapour condenses to a liquid by giving up its latent heat of condensation.
  • the liquid is then expanded into an evaporator which reduces the pressure, and allows work to be done by the liquid, adiabatically wherein it thus takes in latent heat of vaporisation from the surroundings, and once again becomes a vapour. It is in this region of the refrigerator that cooling takes place.
  • the cycle is then repeated, by returning the vapour to the compressor, along a cyclic path.
  • this evaporation is aided by the action of a so-called compressor pump, which pumps vapour out of an evaporator which is located inside the refrigerator, and which consists of several loops of pipe.
  • This pumping out of the refrigerant vapour thus reduces the pressure inside the pipe, so that the latent heat required for the refrigerant to evaporate is taken from the air surrounding the loops of pipe, and, in turn, from the atmosphere, and hence from the food, inside the refrigerator, so that cooling occurs.
  • the compressor pump also compresses the refrigerant vapour inside the condenser pipes of the refrigeration system, which are located on the outside of the refrigerator, at the rear, and it is here that the refrigerant gives up its latent heat of condensation to the surrounding atmosphere, by a process of radiation and convection.

  • the cooling effect which takes place inside the refrigerator is equivalent to the cooling effect on the ambient environment/atmosphere surrounding the thermodynamic panel, which occurs when refrigerant evaporates inside the pipe network of the panel, and takes in its latent heat of evaporation under the pumping-out effect of the operation of the compressor pump.
  • the heat extracted from the ambient atmosphere renders the refrigerant gas hotter than was the refrigerant liquid, and so, the hotter, gaseous refrigerant, now compressed enters the first heat exchanger which is in located inside the hot water cylinder or in thermal communication with water from the cylinder, and this heat is thus given up to the water contained within that cylinder.
  • the now cooler, refrigerant is in a thermodynamic state known as a saturated liquid, and, after entering a filter, it passes to a throttling device, also known as an expansion valve, where it undergoes an abrupt reduction in pressure, which results in the adiabatic flash evaporation of part of the liquid refrigerant.
  • the system of the invention can become the primary means for heating the water, and the existing gas/oil system or any other energy system, can become the secondary, and i.e. back up, heat source.
  • This arrangement will then allow heating of the water, without having to remove the existing cylinder, which is likely to be in satisfactory condition and not in need of replacement, and this therefore: i) reduces cost; ii) reduces wastage; and iii) reduces installation time, from between approximately one to two days, to between three to four hours.
  • An additional option, when installing the new system will be to provide extra insulation to the existing cylinder, by way of a cylinder jacket, in order to reduce heat loss.
  • thermodynamic Box will not have to be installed next to the existing cylinder; and can, instead, be installed above it, or in any other workable location, or in the loft, or garage, or any out building, and the like, wherein the thermodynamic panels can be located away from the cylinder (up to 15 metres vertically, and 30 metres horizontally).
  • thermodynamic panels of the present invention are of such size that two, relatively smaller panels, can be installed by one Installer, rather than two. Also, during transport, and when being manipulated by the Installer, the panels are consequently less flexible, and so are likely to suffer less damage. Moreover, by being smaller, there is greater flexibility with respect to installation in various locations. Thus, for instance, the panels can be installed; i) one on top of the other, or ii) side by side; or iii) one on either side of a window, etc.
  • thermodynamic panels are supplied in sizes of 1 .9 m by 0.9 m, and 2 m by 0.8 m, whilst the panels of the present invention are supplied in sizes of 1 .4 m by 0.6 m, and 1 .0 m by 0.6 m; each having a thickness of 5 mm, wherein each of the panels of either size, can be connected in a side-by-side configuration, or in a one-above-the other, configuration.

  • the hot refrigerant gas is a vapour; that is, a gas which is below its critical temperature, it can be liquefied by the application of pressure.

This vapour can then be compressed by means of the compressor pump, 5, and so that, provided that the accompanying change is adiabatic; and thus takes place without heat entering or leaving the system; the temperature of the vapour can rise, due to work being done on it by the compressor, 5.
