Definitions

  • the invention relates to a plant for producing sanitary hot water.
  • a plant for producing sanitary hot water is intended to supply in particular a single dwelling or group dwellings.
  • the needs of a plant intended for the ventilation of the dwelling are significantly reduced by using a double flow ventilation, allowing to recover calories on the extracted airflow in order to transfer them to the injected airflow or by using a modulated ventilation, the operation of which is limited to actual and functional needs, for example, on the hygrometry rate inside the dwelling.
  • thermodynamic circuit within which flows a coolant fluid
  • thermodynamic circuit having an evaporator for exchanging heat with the extracted air, a compressor, an expander and a condenser for exchanging heat with the fluid contained in the tank.
  • thermodynamic water heater on the extracted air Such a plant is generally designated by the term “thermodynamic water heater on the extracted air”.
  • Such a type of plant allows recovering part of the heat of the extracted air and transferring it to the fluid contained in the tank of the water heater, through the thermodynamic circuit and heat exchangers formed by the evaporator and the condenser.
  • This type of plant requires airflow substantially constant and significant in order to heat the water in the tank. Indeed, in the case where the airflow is reduced, the performance of the plant deteriorates and appears the risk of icing in the extracted air.
  • the ventilation system used by this type of plant is necessarily a constant flow system, the flow value being of a sufficient value to ensure the operation of the plant.
  • Such an extracted airflow creates significant heat losses in the dwelling.
  • Another disadvantage of this type of plant is to operate only on starting or on stopping, the hysteresis of operation being monitored through a temperature probe for measuring the temperature of the distributed sanitary hot water. So that, when the temperature of the sanitary hot water is below a predetermined low value, the compressor is started so that the water contained in the tank is heated. When the water temperature exceeds a predetermined high value, the compressor is stopped.
  • the invention attempts to remedy these drawbacks by providing a plant for producing sanitary hot water by optimising the recovery of thermal energy available in the extracted air, while limiting the energy consumption required for the operation of the plant.
  • the invention relates to a plant for producing sanitary hot water of the aforesaid type, characterised in that the ventilation system is equipped with means for adjusting the extracted airflow, for example based on the hygrometry, and in that the compressor is a variable speed compressor, capable to modify the flow of coolant fluid.
  • the extracted airflow may be modulated or adjusted according to the ventilation needs of the building.
  • variable speed compressor generally called compressor of the “inverter” type
  • compressor of the “inverter” type allows adjusting the flow of the coolant fluid based on the available heat or being able to be drawn from the extracted air, so as to ensure the proper functioning of the plant. This is how, for example, a reduction of the flow of extracted air is followed by a reduction in compressor speed and hence a decrease in the amount of heat taken from the extracted air, in order to avoid any icing phenomenon.
  • the adjustment of the compressor speed allows enabling to operate it at low speed whenever possible, so that the energy consumption linked to the operation of the compressor is greatly reduced.
  • the plant includes means providing information on the extracted airflow, interacting with the compressor to adjust the flow of the coolant fluid in the corresponding circuit based on the measured airflow.
  • Measurement of airflow provides direct information on the amount of available energy that may be drawn from the extracted air and then transferred to the fluid contained in the tank of the water heater.
  • the plant includes at least one extracted air temperature probe, located downstream of the evaporator in the direction of air and interacting with the compressor to adjust the flow of coolant fluid into the corresponding circuit according to the temperature of the measured air.
  • Measurement of the extracted air temperature provides indirect information on the amount of energy available that may be drawn. Indeed, the extracted air temperature, downstream of the evaporator is as much further reduced as the remaining energy contained in the extracted air is low.
  • the temperature probe could be located upstream of the evaporator.
  • the invention includes at least one temperature probe, capable of measuring the temperature of the fluid contained in the water heater tank, interacting with the compressor so as to adjust the flow of the coolant fluid into the corresponding circuit, based on the temperature of the measured fluid.
  • Measurement of the temperature of the fluid in the tank allows obtaining information on the status of the sanitary hot water reserve and allows to maximise the time and speed of the operation of the compressor.
  • the plant includes a plurality of temperature probes, located at different tank levels, so as to measure the temperature of a plurality of fluid layers contained in the tank.
  • the means for measuring the extracted airflow, the temperature probe of the extracted air and/or the temperature probe of the fluid are connected to a central control unit designed to adjust the compressor speed based on measured airflow, of the temperature of the measured air and/or the temperature of the measured fluid.
  • the condenser is located inside the water heater tank so as to exchange directly heat with the fluid contained in the tank.
  • the plant includes a secondary circuit of heat exchange within which flows a heat transfer fluid passing through the condenser to exchange heat with the coolant, the secondary circuit further includes a heat exchanger located within the water heater tank, so as to exchange heat with the fluid in the tank.
  • the heat exchanger of the secondary circuit is a coil.
  • the controlled mechanical ventilation system includes at least one air vent intended for the passage of extracted air, the adjusting means for the extracted airflow including adjusting means for the opening of the air vent.
  • the air vent may be opened fully. This is particularly the case during the operation phases of the thermodynamic circuit compressor, in order to maximise heat exchanges between the extracted air and the fluid to be heated contained in the tank.
  • the controlled mechanical ventilation system includes at least one first air vent intended for the passage of extracted air, the adjusting means of the extracted airflow including at least one second air vent and control means designed to control the opening and closing of the second air vent.
  • the second air vent plays a similar role to that described above. Indeed, when it is desired to increase the extracted airflow, it is sufficient to open the second air vent. In order to improve the comfort of the residents, it may also be useful to increase the extracted airflow during summer, so as to over ventilate a room of the home, especially at night.
  • the second air vent may be located at a heat source, for example behind a refrigerator, in order to increase the performances of the plant for producing sanitary hot water.
  • the second air vent may also be located in a living room so as to over ventilate the said room during summer and during the night, in order to improve comfort for residents.
  • FIG. 1 is a schematic view of a first embodiment of the invention
  • FIG. 2 is a view corresponding to FIG. 1 , of a second embodiment of the invention.
  • FIG. 4 is a diagram showing, for the first mode of operation, the cumulated consumption of the compressor based on time
  • FIGS. 5 and 6 are diagrams corresponding to those of FIGS. 3 and 4 , for a second mode of operation of the plant.
  • FIG. 1 shows a first embodiment of a plant for producing sanitary hot water according to the invention.
  • the latter includes a water heater comprising a tank 1 within which is stored fluid to be heated, and a controlled mechanical ventilation system 2 intended for extracting air from a dwelling.
  • the controlled mechanical ventilation system 2 is equipped with means for adjusting extracted airflow, for example based on the hygrometry, and is coupled to a thermodynamic circuit 3 within which flows a coolant fluid.
  • the thermodynamic circuit 3 includes successively, in the direction of flow of the coolant fluid, an evaporator 4 for exchanging heat with the extracted air 5 , a compressor 6 , a condenser 7 for exchanging heat with the fluid contained in a tank 1 , and an expander 8 .
  • the flow direction of the coolant fluid is shown by arrows.
  • the phase and the pressure of the coolant fluid are identified by references VBD (Low Steam Pressure), VHP (High Steam Pressure), LHP (Liquid High Pressure) and LBP (Liquid Low Pressure).
  • the compressor 6 is a variable speed compressor, capable of modifying the flow of the coolant fluid.
  • the condenser 7 is located inside the water heater tank 1 , so as to exchange directly heat with the fluid contained in the tank 1 .
  • the plant also includes means 9 for measuring the flow of extracted air, a temperature probe 10 for the extracted air, located downstream of the evaporator 4 in the direction of airflow, and a plurality of temperature probes 11 , located at different levels of the tank 1 and capable of measuring the temperature of a plurality of layers of the fluid contained in the tank 1 .
  • the means 9 for measuring airflow, the air temperature probe 10 and/or the fluid temperature probes 11 are connected to a central control unit 12 designed to adjust the speed of the compressor 6 based on the measured airflow, the measured air temperature and/or the measured fluid temperature.
  • the condenser 7 is located outside the tank.
  • the plant also includes a secondary circuit 13 of heat exchange, equipped with a pump 14 and within which flows a coolant fluid.
  • the secondary circuit 13 passes through the condenser 7 so as to exchange heat with the coolant fluid.
  • the secondary circuit 13 also includes a heat exchanger 15 in the shape of a coil, located within the tank 1 of the water heater, so as to exchange heat with the fluid contained in the tank 1 .
  • the diagram in FIG. 3 includes a first curve, referenced ( 1 ), showing the operation of a plant of the classical thermodynamic water heater type, and a second curve, referenced ( 2 ), showing the operation of the plant according to the invention.
  • This Figure shows the operation of the aforementioned plants for a constant extracted airflow of Q 1 value.
  • the compressor is started in the time interval between t 0 and t 1 , the fixed-speed compressor power of this plant being equal to P 1 .
  • FIG. 5 shows another mode of operation wherein the extracted airflow Q 1 during the time interval t 3 to t 4 is reduced and equal to Q 2 during the time interval t 4 to t 5 .
  • This mode of operation is that of the modulated ventilation system, wherein the extracted airflow is adjusted based on the needs.
  • the compressor 6 may for example operate at full speed during the time interval t 3 to t 4 , then at a reduced speed during the time interval t 4 to t 5 , so as to avoid problems due to icing. The performance of the plant is therefore increased. In addition, consumption of the compressor 6 operating at reduced speed is also reduced.
  • the plant according to the invention is capable to operate in combination with a modulated ventilation system 3 . It is recalled that such a system allows limiting thermal losses due to hot air extraction, these losses being also limited by the fact that the plant according to the invention allows to recover part of the heat from the extracted air, and this, regardless of the extracted airflow.
  • the controlled mechanical ventilation system includes one or more air vents intended for passing the extracted air, adjusting means allowing adjusting the opening of the said air vents.
  • the controlled mechanical ventilation system includes at least a first air vent, intended for the passage of the extracted air during normal operation, and at least a second air vent.
  • Control means designed to control the opening and the closing of the second air vent allow passing from a state of normal operation wherein the extracted air passes only through the first air vent in a state called of over-ventilation wherein air is extracted both through the first and the second air vents.
