Definitions

  • the present invention relates to storing hot water at temperature, comprising a storage vessel for hot water provided with a feed and a discharge for water.
  • a storage vessel assembly of this type is disclosed in European Application 0557994A1. This
  • Application describes a vessel that is provided in the interior with a partition, by means of which two compartments are delimited. Water circulates between these two compartments even when water is not withdrawn. With this arrangement one of the two compartments can be brought to a relatively high temperature. Heating water to a relatively high temperature is important in order to prevent the multiplication of microrganisms as far as possible. By this means it is possible to counteract the occurrence of diseases and other harmful effects.
  • One of the best known examples is the occurrence of legionella infection. If hot water is stored at a relatively low temperature there is a risk that such microorganisms multiply very rapidly, with all of the associated harmful consequences.
  • the aim is to lower the temperature of hot water for domestic use and other applications as much as possible in order to restrict energy losses as far as possible.
  • the aim of the present invention is to avoid this disadvantage and to provide a relatively simple storage vessel assembly with which, on the one hand, the formation of harmful microorganisms is prevented in a guaranteed manner and with which, on the other hand, the consumption of energy is restricted as far as possible.
  • a further aim of the present invention is to be able to implement this improvement both in the case of new installations to be constructed and in the case of existing installations without this incurring high additional costs.
  • a storage vessel assembly as described above, in that there is an auxiliary heating unit, located outside the storage vessel, for heating said water to a temperature above the temperature in said vessel, which auxiliary heating unit is provided with an inlet line and outlet line for water, which lines are connected to said storage vessel via a pump.
  • auxiliary heating unit located outside the storage vessel, for heating said water to a temperature above the temperature in said vessel, which auxiliary heating unit is provided with an inlet line and outlet line for water, which lines are connected to said storage vessel via a pump.
  • auxiliary heating unit located outside the storage vessel, for heating said water to a temperature above the temperature in said vessel, which auxiliary heating unit is provided with an inlet line and outlet line for water, which lines are connected to said storage vessel via a pump.
  • auxiliary heating unit consumes only little energy, it is possible to obtain this energy in an environmentally friendly manner.
  • Solar energy can be used, either directly via a so-called solar collector or indirectly via photovoltaic elements. It is also possible to use a heat pump, on its own or in combination with other energy sources. Different energy sources can be used for the main heating system and the auxiliary heating unit.
  • the temperature in the auxiliary heating unit must be substantially higher than 60 °C.
  • a heat exchanger is installed between the inlet line and outlet line of this auxiliary heating unit. That is to say, the water from the auxiliary heating unit that has been heated to a higher temperature is re-cooled to the temperature in the inlet line before it enters the vessel. It is relatively simple to construct a heat exchanger with an efficiency such that the temperature jump over such a heat exchanger is less than 3 °C. As a result, the water that is returned to the vessel is only 3 °C hotter, compared with the temperature in the vessel. Because, moreover, the quantity concerned is relatively small, the energy requirement of the auxiliary heating unit will be relatively low.
  • the invention also relates to a method for storing water in a vessel at a relatively low temperature, that is to say at a temperature lower than 60 °C. As described above, small amounts of water are withdrawn from the vessel and heated to a temperature substantially above 60 °C.
  • the construction according to the present invention can be used with simple systems with a single hot water line.
  • the system according to the present invention can also be used with systems which have an indirect heating coil where heated water is circulated continuously. In this case the return water can be externally heated. This heating system must be differentiated from the auxiliary heating unit according to the invention.
  • the storage vessel according to the invention can itself be provided with a main heating system, but it is also possible to supply the vessel with water heated in some way or other.
  • the storage vessel for storing hot water is indicated by 1.
  • the hot water inside this storage vessel is at a temperature of approximately 60 °C in the top section thereof.
  • the temperature in the bottom section is approximately 40 °C.
  • Cold water is supplied via line 2 and hot water is discharged with the aid of line 3. Downstream of one or more tapping points, line 3 is provided with a return system so that continuous circulation of hot water can be achieved.
  • the main heating system 4 provides for heating hot water.
  • a central heating boiler 20 can be used for this purpose. Water issuing from discharge 3 is supplied to the users, shown diagrammatically, and fed back.
  • auxiliary heating unit 9 there is an auxiliary heating unit 9. This can be powered in any manner known in the state of the art.
  • a heat exchanger 13 is connected upstream of this auxiliary heating unit 9.
  • Line 11 is connected to a pump 10 and opens into a bottom region of the storage vessel 1, whilst line 12, the outlet line, opens into the vessel at a higher point. Circulation takes place from inlet line 11 through auxiliary heating unit 9 to outlet line 12.
  • the heat introduced into the water in auxiliary heating unit 9 can be essentially completely discharged from outlet line 12 to inlet line 11. That is to say there is only a small temperature jump of, for example, less than 3 °C over heat exchanger 13.
  • auxiliary heating unit 9 heats the water to approximately 75 °C only a very small amount of energy will be required. After all, only a very restricted fraction of the quantity of water in the storage vessel 1 is heated, whilst, moreover, the major proportion of the heat from heating is recovered in heat exchanger 13.
  • inlet line 11 is connected directly to feed line 2. That is to say the water entering the system is always subjected to a heat treatment in an auxiliary heating unit 9. At the temperature prevailing in the storage vessel 1 there is a risk that microorganisms will multiply rapidly. Legionella may be mentioned as an example in this context.
  • This risk can be limited or even excluded by, in accordance with the invention, continuously or intermittently heating a fraction of the water present in the storage vessel to a temperature at which the effect of these microorganisms is largely destroyed.
  • the speed of circulation through the auxiliary heating unit 9 is dependent on the temperature in the storage vessel. Under adverse conditions, the contents of the storage vessel can be heated every hour, but under favourable conditions this can take place once a day.
  • the installation according to the present invention it is, on the one hand, possible to render such microorganisms harmless in a controlled manner and, on the other hand, the temperature in the storage vessel can be kept relatively low. Furthermore, the energy requirement for the temporary heating of the water to render such microorganisms harmless is very restricted.

Abstract

La présente invention concerne un ensemble cuve de stockage permettant de stocker de l'eau chaude à basse température, ainsi qu'un procédé permettant de stocker de l'eau chaude. L'objectif de cette invention est d'inhiber les bactéries Legionella et d'autres micro-organismes pouvant provoquer des maladies. Afin d'atteindre cet objectif, il est proposé de soumettre de manière continue une partie de l'eau présente dans ladite cuve temporairement à une haute température qui rend ces micro-organismes inoffensifs, tout en maintenant la température relativement basse dans ladite cuve de stockage.
