Definitions

  • the present invention relates to reducing water flow and/or energy flow to water outlets, in a water provision system to conserve water and/or energy.
  • heated water is required throughout the day all year round. It goes without saying that the provision of heated water requires both clean water and a source of heat.
  • a heating system is provided to an often centralised water provision system to heat water up to a predetermined temperature e.g. set by a user, and the heat source used is conventionally one or more electric heating elements or burning of natural gas.
  • the heat source used is conventionally one or more electric heating elements or burning of natural gas.
  • utilities providers would implement a peak tariff which increases the unit cost of energy, partly to cover the additional cost of having to purchase more energy to supply to customers and partly to discourage unnecessary energy usage.
  • Clean water as a utility is currently receiving much attention.
  • As clean water becomes scarcer there has been much effort to educate the public on the conservation of clean water as well as development of systems and devices that reduce water consumption, such as aerated showers and taps to reduce water flow, showers and taps equipped with motion sensors that stop the flow of water when no motion is detected, etc.
  • systems and devices are restricted to a single specific use and only have limited impact on problematic water consumption habits.
  • a heat pump is a device that transfers thermal energy from a source of heat to a thermal reservoir.
  • a heat pump requires electricity to accomplish the work of transferring thermal energy from the heat source to the thermal reservoir, it is generally more efficient than electrical resistance heaters (electrical heating elements) as it typically has a coefficient of performance of at least 3 or 4. This means under equal electricity usage 3 or 4 times the amount of heat can be provided to users via heat pumps compared to electrical resistance heaters.
  • the heat transfer medium that carries the thermal energy is known as a refrigerant.
  • Thermal energy from the air e.g. outside air, or air from a hot room in the house
  • a ground source e.g. ground loop or water filled borehole
  • the now higher energy refrigerant is compressed, causing it to raise temperature considerably, where this now hot refrigerant exchanges thermal energy via a heat exchanger to a heating water loop.
  • heat extracted by the heat pump can be transferred to water in an insulated tank that acts as a thermal energy storage, and the heated water may be used at a later time when needed.
  • the heated water may be diverted to one or more water outlets, e.g. a tap, a shower, a radiator, as required.
  • a heat pump generally requires more time compared to electrical resistance heaters to get water up to the desired temperature.
  • CN 112 068 615 discloses a kitchen and bath intelligent comfortable wash basin based on temperature and infrared sensing analysis. According to comparative analysis of a first temperature sensor and a lowest threshold value of the suitable temperature and comparative analysis of a third temperature sensor and the lowest threshold value of the suitable temperature, the on-off action of an electric valve mechanism is driven and adjusted, and meanwhile the heating action of an electric heating mechanism is driven and adjusted.
  • the invention provides a heater arrangement system for a water provision system for controlling a water supply provided to a water outlet, as claimed in claim 1.
  • the invention also provides a method of controlling a water supply provided to a water outlet, as claimed in claim 7.
  • the invention further provides a corresponding computer program product and a control module, as claimed in claims 13 and 14.
  • a temperature of heated water emerging from a water outlet is reduced when it is determined that there is an absence of any object beneath the water outlet, such that energy (due to the lower temperature of the water) usage may be reduced when it is not required.
  • a warning such as a sound or flashing light is initiated when it is determined that a water outlet has been continuously providing heated water for a first period of time, and ceases provision of heated water when it is determined that the water outlet has been continuously providing heated water for a longer second period of time, such that water and/or energy usage may be reduced when it is deemed unnecessary and furthermore flooding is prevented.
  • a report may be generate based on collected heated water usage data, for example to prompt users to modify their usage habits.
  • heated water is provided to a plurality of water outlets, including taps, showers, radiators, etc., in a building, such as a private residential house or commercial space, by a centralized water heating system.
  • the water heating system may comprise one or more electric heating elements for directly heating cold water to a temperature controlled by the amount of energy supplied to the one or more electric heating elements.
  • the water heating system may further comprise a less direct, slower acting but cost-saving and environmentally friendly heat source for heating water, for example in the form of a heat pump for extracting thermal energy from the surroundings and/or a thermal energy storage e.g. comprising phase change material for storing thermal energy as latent heat to be later extracted for heating cold water to a temperature determined by the amount of thermal energy stored within the thermal energy storage.
  • the water heating system is controlled by means of a control module communicatively coupled to the water heating system configured for example to modulating power supplied to the one or more electric heating elements, to activate or otherwise control and modulate power supplied to the heat pump.
  • cold and heated water is provided by a centralized water provision system to a plurality of water outlets, including taps, showers, radiators, etc., for a building in a domestic or commercial setting.
  • An exemplary water provision system according to an embodiment is shown in Fig. 1 .
  • the water provision system 100 comprises a control module 110.
  • the control module 110 is communicatively coupled to, and configured to control, various elements of the water provision system, including flow control 130 for example in the form of one or more valves arranged to control the flow of water internal and external to the system, a (ground source or air source) heat pump 140 configured to extract heat from the surroundings and deposit the extracted heat in a thermal energy storage 150 to be used to heat water, and one or more electric heating elements 160 configured to directly heat cold water to a desired temperature by controlling the amount of energy supplied to the electric heating elements 160. Heated water, whether heated by the thermal energy storage 150 or heated by the electric heating elements 160, is then directed to one or more water outlets as and when needed.
  • the heat pump 140 extracts heat from the surroundings into a thermal energy storage medium within the thermal energy storage 150.
  • the thermal energy storage medium may in addition be heated by other sources.
  • the thermal energy storage medium is heated until it reaches a desired operation temperature, then cold water e.g. from the mains can be heated by the thermal energy storage medium to the desired temperature.
  • the heated water may then be supplied to various water outlets in the system.
  • the control module 110 is configured to receive input from a plurality of sensors 170-1, 170-2, 170-3, ..., 170-n.
  • the plurality of sensors 170-1, 170-2, 170-3, ..., 170-n may for example include one or more air temperature sensors disposed indoor and/or outdoor, one or more water temperature sensors, one or more water pressure sensors, one or more timers, one or more motion sensors, and may include other sensors not directly linked to the water provision system 100 such as a GPS signal receiver, calendar, weather forecasting app on e.g. a smartphone carried by an occupant and in communication with the control module via a communication channel.
  • the control module 110 is configured, in the present embodiment, to use the received input to perform a variety of control functions, for example controlling the flow of water through the flow control 130 to the thermal energy storage 150 or electric heating elements 160 to heat water.
  • a heat pump While a heat pump is generally more energy efficient for heating water compared to an electrical resistance heater, a heat pump requires time to start up as it performs various checks and cycles before reaching a normal operation state, and time to transfer sufficient amount of thermal energy into a thermal energy storage medium before reaching the desired operation temperature.
  • an electrical resistance heater is generally able to provide heat more immediately.
  • a heat pump can take longer to heat the same amount of water to the same temperature compared to an electrical resistance heater.
  • the heat pump 140 may for example use a phase change material (PCM), which changes from a solid to a liquid upon heating, as a thermal energy storage medium.
  • PCM phase change material
  • a phase change material may be used as a thermal storage medium for the heat pump.
  • phase change materials are paraffin waxes which have a solid-liquid phase change at temperatures of interest for domestic hot water supplies and for use in combination with heat pumps.
  • paraffin waxes that melt at temperatures in the range 40 to 60 degrees Celsius (°C), and within this range waxes can be found that melt at different temperatures to suit specific applications.
  • Typical latent heat capacity is between about 180kJ/kg and 230kJ/kg and a specific heat capacity of perhaps 2.27Jg -1 K -1 in the liquid phase, and 2.1Jg -1 K -1 in the solid phase. It can be seen that very considerable amounts of energy can be stored taking using the latent heat of fusion.
  • More energy can also be stored by heating the phase change liquid above its melting point.
  • the heat pump may be operated to "charge” the thermal energy storage to a higher-than-normal temperature to "overheat" the thermal energy storage.
  • a suitable choice of wax may be one with a melting point at around 48°C, such as n-tricosane C 23 , or paraffin C 20 -C 33 , which requires the heat pump to operate at a temperature of around 51°C, and is capable of heating water to a satisfactory temperature of around 45°C for general domestic hot water, sufficient for e.g. kitchen taps, shower/bathroom taps. Cold water may be added to a flow to reduce water temperature if desired. Consideration is given to the temperature performance of the heat pump. Generally, the maximum difference between the input and output temperature of the fluid heated by the heat pump is preferably kept in the range of 5°C to 7°C, although it can be as high as 10°C.
  • salt hydrates are also suitable for latent heat energy storage systems such as the present ones.
  • Salt hydrates in this context are mixtures of inorganic salts and water, with the phase change involving the loss of all or much of their water. At the phase transition, the hydrate crystals are divided into anhydrous (or less aqueous) salt and water.
  • Advantages of salt hydrates are that they have much higher thermal conductivities than paraffin waxes (between 2 to 5 times higher), and a much smaller volume change with phase transition.
  • a suitable salt hydrate for the current application is Na 2 S 2 O 3 ⁇ 5H 2 O, which has a melting point around 48°C to 49°C, and latent heat of 200-220 kJ/kg.
  • Fig. 2 shows an embodiment of a method for controlling utility usage, for example in a home environment.
  • the method begins at S2001 when a water outlet (for example, a bathroom sink tap) is activated or turned on by a user to receive heated water supplied by a water heating system disposed remotely from the water outlet, the water heating system being controlled by a control module 110 of Fig. 1 , disposed remotely from the water outlet and in communication with a sensor (for example, one of the sensors 170-n, shown in Fig. 1 ) disposed at or near the water outlet for sensing the presence of an object (for example, a hand of the person who is washing his hands) below the water outlet.
  • a water outlet for example, a bathroom sink tap
  • the control module 110 receives a signal from the sensor and determines at S2003 whether an object is present below the water outlet. If the control module determines that an object is present, the method returns to S2002 and the control module continues to monitor signals from the sensor. If the control module determines that there is no object below the water outlet, at S2004, the control module controls the water heating system to reduce the temperature of the heated water supplied to the water outlet and optionally reduce the flow rate of the heated water supplied to the water outlet. The method then returns to S2002 and the control module continues to monitor signals from the sensor. In doing so, heated water may continue to be supplied to the water outlet but with reduced energy and optionally reduced water usage.
  • the control module reduces the temperature and the flow of heated water to conserve energy and water, then once the user return their hands to the tap, the temperature and the flow of heated water can be brought back to the initial level.
  • a timer in communication with the control module is activated to record an elapsed time.
  • the control module receives signals from the timer to determine the elapsed time T for the continuous provision of heated water from the water outlet. If the control module determines at S2006 that the elapsed time T does not exceed a predetermined first threshold T1, the method returns to S2005 and the control module continues to monitor signals from the timer.
  • the control module determines at S2006 that the elapsed time T exceeds the first threshold T1
  • the control module initiate a warning sequence at S2007, which may include producing a sound or activating a light signal at or near the water outlet to warn the user that the water outlet has been continuously on for a time T1 to prompt the user to turn the water outlet off if heated water is no longer needed.
  • the control module determines whether the elapsed time T exceeds a predetermined second threshold T2, which is higher than the first threshold T1. If it is determined that the elapsed time T does not exceed the second threshold T2, the method returns to S2005 and the control module continues to monitor signals from the timer.
  • control module determines at S2008 that the elapsed time T exceeds the second threshold T2
  • the control module then controls the water heating system such that the water outlet is completely closed, thereby ceasing provision of heated water to the water outlet at S2009. In doing so, energy and water are not wasted when heated water is no longer required. For example, if the user forgets to turn off the tap after washing hands, or if a child has left the tap on for play, provision of heated water can stop automatically to conserve energy and water.
  • heated water usage data (52010) collected over time can be used to generate a usage report (S2011) as a tool to prompt a user to review and potentially modify their usage habits to reduce energy and water usage.
