    INSTALLATION OF VENTILATION AND HOT WATER PRODUCTION FOR COLLECTIVE HOUSING
    The present invention relates to a ventilation installation and production of domestic hot water for collective housing.
    It is particularly suitable when the collective housing is not provided with a hot water distribution loop which supplies hot water to several or all the dwellings of the dwelling.
    In order to produce the hot water that is necessary for a residential dwelling, it is known to use a thermodynamic water heater as shown in FIG. 1. Such a thermodynamic water heater 10 comprises a tank 1 in which is contains the water to be heated, and a heat pump which is arranged to transfer heat between the air which is extracted from the housing and the water which is contained in the tank 1. The heat pump usually comprises a circuit thermodynamics inside which circulates a refrigerant. This thermodynamic circuit comprises an evaporator 2, which is arranged to recover heat from the extracted air, a compressor 3, an expander 5, and a condenser 4 which is arranged to transfer heat to the water contained in the tank 1. Optionally, the compressor 3 and the expander 5 may be of the electronically controlled variable speed type, to optimize the production yield of hot water by taking into account the real values of various parameters such as the temperature of the air and air flow. In this way, a faster heat transfer is obtained, and a higher reactivity compared to variations in the hot water requirement or the heat source that is the air that passes through the water heater. References 6 and 7 respectively denote the cold water supply inlet and the hot water outlet of the water heater 10. Optionally also, the thermodynamic water heater 10 may further comprise a motorized ventilation unit 8, which activates or assists the circulation through the evaporator 2 of the air that is extracted from the housing. Alternatively, such a ventilation unit may be provided outside the water heater.
    The document FR 2 926 626 describes equipping each dwelling of a collective dwelling with a thermodynamic water heater which is dedicated to this dwelling. Such an installation is illustrated in FIG. 2, in which the references indicated have the following meanings: 100 the collective dwelling as a whole, for example a building with four levels XA and XB two independent dwellings of level X in the collective dwelling 100, withX = 1,2, 3 or 4 1XY vents and exhaust ducts dedicated to housing
    XY, with Y = A or B
    2XY thermodynamic water heater dedicated to the housing XY 102 air collection box extract 103 ventilation unit ensuring the extraction of air to the outside of the collective housing 100 101Y collective exhaust air duct connected in upstream to the thermodynamic water heaters of the XY housings, and connected downstream to the extracted air collection box 103
    For the housing 1A, the air extraction ducts 11A are connected to the air intake of the evaporator 2 of the heat pump of the water heater 21 A. The extraction ducts 11A may have a any topology, possibly with groupings of ducts which come from different parts of the housing 1A. The air outlet of the evaporator 2 is connected to the collective extraction duct 101 A. Similar aeraulic connections are made for each of the dwellings XY. However, the number and arrangement of 1XY air outlets and ducts may vary between two XY housings different from the collective dwelling 100.
    Thus, the air that is extracted from one of the dwellings is used to produce the hot water that is used in this dwelling, by means of the thermodynamic water heater of the same dwelling. But such a management of residential fluids has the following disadvantages: - the consumption of domestic hot water of each dwelling individually can be insufficient compared to the capacity of the thermodynamic water heater which is dedicated to this housing, so that the value coefficient of performance of the water heater is not optimal. Conversely, the momentary consumption of hot water in a dwelling may be greater than the capacity of the water heater, requiring the use of additional heating resistance or causing a shortage of temporary hot water. Such equipment for producing domestic hot water, separately by housing, does not exploit the statistical compensation for variations in hot water consumption that can occur between different dwellings. In the jargon of the skilled person, such a statistical compensation is called expansion; - The thermodynamic water heater of each housing is then located in the housing to which it is dedicated, causing congestion thereof. In addition, if an air filter is located in the air extraction circuit of the housing, upstream of the heat pump, the hardware access of a maintenance operator to the filter can be difficult. The replacement of the filter when it becomes dirty then becomes longer and inconvenient.
    The present invention therefore aims to remedy at least some of these disadvantages.
    For this purpose, a first aspect of the invention proposes a new ventilation and hot water production installation for a collective dwelling, which comprises a plurality of dwellings and at least one air extraction network which is arranged to extracting air from at least some of the dwellings. The installation comprises at least two water heaters, each of these water heaters comprising itself a tank in which is contained water to be heated, and heat pump means which are arranged to transfer heat between at least a portion of the extracted air passing through this water heater and the water contained in the tank, so as to heat the water to produce hot water. Each water heater is therefore of the thermodynamic type.
    According to the invention, each water heater is connected at the outlet by hot water transport pipes to sanitary elements of at least two separate dwellings inside the collective dwelling, so as to supply hot water these said at least two separate dwellings from the same water heater. In other words, each thermodynamic water heater is shared between several dwellings of the collective dwelling.
    Thus, the capacity of the water heater can be better used, since the hot water consumption is multiplied by the number of dwellings that are served from the same water heater. In addition, this hot water consumption can be more distributed throughout a day, depending on consumption periods that can vary, including being shifted, between the occupants of different homes. In other words, an installation that is in accordance with the invention takes advantage of the expansion that exists between the dwellings. In this way, the value of the coefficient of performance of the thermodynamic water heater can be improved.
    In addition, the thermodynamic water heater which is thus shared between several dwellings can be installed in a collective part of the house, avoiding cluttering the interior of each dwelling. Such placement of the thermodynamic water heater in a collective part can also facilitate access to the device for maintenance. In particular, access to at least one air filter that can be located in the air extraction network upstream of the heat pump means of the water heater, can thus be facilitated to ensure the replacement or the cleaning the filter.
    Finally, the cost of the water heater and its maintenance is also shared between the dwellings, resulting in reduced individual participation in payment for each owner of one of the dwellings.
    In addition, vis-à-vis an installation where there is only one collective water heater for the entire collective housing, this type of installation associated with the invention has the advantage of avoiding or at a minimum to minimize energy losses related to the distribution loop or tracing.
    Finally, the extracted air that passes through the water heater can come from several homes, so that its flow is both higher and more regular statistical effect. The value of the coefficient of performance can be further increased for this reason.
    Furthermore, compared to a collective hot water production installation that would include only one water heater to serve all housing of the house, the use of at least two water heaters according to the invention reduces the length of the pipes that supply each dwelling with domestic hot water. The use of continuous hot water circulation loops, or electrical heaters for heating the hot water pipes to some of the most remote dwellings of the water heater, is no longer necessary. The actual delivery time of hot water in one of the housing, from the opening of the tap by the occupant of the housing, is also reduced in this way.
    In preferred embodiments of the invention, one or more of the following improvements may be used, separately or in combination of several of them: - at least one water heater may be located in a common part of the collective dwelling, such as a collective entrance hall of the dwelling, a technical room, a floor landing, or a technical duct; - The separate dwellings that are supplied with hot water from the same water heater, may be located on the same floor as this water heater in the collective housing. At least these dwellings are advantageously located each on a floor which is close to that of the water heater; - The air extraction network can be arranged to bring to the heat pump means of one of the water heater, the air that is extracted from those of the housing of the collective dwelling that are powered in hot water from this water heater. In other words, the units from which the air that passes through the water heater is extracted are the same as those served with hot water by this water heater. Possibly, the installation may further comprise an additional air intake and a duct that connects this additional air intake to the heat pump means of the water heater, to bring to these heat pump means an amount of additional air in addition to the air that is extracted from the homes supplied with hot water from the water heater; for at least one of the water heaters of the installation, the air extraction network may comprise a bypass path, which is arranged in a bypass between an inlet and an outlet of the heat pump means, the outside of these, so that an adjustable portion, between 0% and 100%, inclusive limit values, of the air that comes from the housing is extracted without crossing the heat pump means; the air extraction network may comprise air intakes which are located in the housings, and at least one collection plenum which is connected downstream to an air inlet of the heat pump means of a water heaters, and connected upstream to the air intakes of the housing, so as to supply the heat pump means through the plenum with the air extracted from the housing; the air extraction network may comprise at least one air filter which is arranged upstream of an air circulation path in the heat pump means of at least one water heater , called a water heater inlet filter, and also include a ventilation unit which is disposed downstream of this air circulation path in the heat pump means of the water heater, or which is disposed in the water heater itself. In this case, the air extraction network may furthermore comprise: a pressure sensor which is disposed upstream of the water heater inlet filter; and. a control unit, which is adapted to vary an operating setpoint of the ventilation unit according to a measurement signal produced by the pressure sensor; - the installation can furthermore include:. a sewage disposal pipe; and. a heat exchanger, which is arranged between the sewage pipe and a supply pipe of one of the cold water heaters, for transferring from the sewage a quantity of heat to the cold water supplying the water heater before this water is heated by the water heater; the heat pump means of at least one water heater may comprise a thermodynamic circuit inside which a refrigerant circulates, this thermodynamic circuit comprising an evaporator which is arranged to recover heat from the extract air, a compressor, an expander, and a condenser which is arranged to transfer heat to the water contained in the reservoir. In this case, the compressor and the expander may advantageously be of the electronically controlled variable speed type. The value of the coefficient of performance can thus be further improved, regardless of the flow of hot water that is produced; - Finally, the installation may further comprise at least one hot water meter which is disposed on one of the hot water transport pipes which supplies hot water to one of the housing from one of the water heaters.
    A second aspect of the invention relates to a thermodynamic water heater which is adapted for a ventilation and hot water production installation, according to the first aspect of the invention. Such a water heater comprises a reservoir in which is contained water to be heated, and heat pump means which are arranged to transfer heat between the air passing through the water heater and the water contained in the tank, so as to heat this water to produce domestic hot water. The water heater of the second aspect of the invention is adapted to be connected at the outlet by hot water transport pipes to sanitary elements of a housing subassembly of a collective dwelling, this subassembly comprising at least two separate dwellings inside the collective dwelling, so as to supply hot water to these at least two dwellings. In particular, the adaptations of the water heater may relate to the capacity of its tank, preferably between 300 liters and 1000 liters, its hot water outlet which is divided to serve several homes, its association with several consumption meters that are arranged each on one of the divisions of the hot water outlet of the water heater, its combination with an air duct bypassing the heat exchanger, etc. Other features and advantages of the present invention will appear in the following description of nonlimiting exemplary embodiments, with reference to the accompanying drawings, in which: FIG. 1, already described, represents a thermodynamic water heater such that known before the present invention, and used in the invention; - Figure 2, already described, illustrates a ventilation installation and production of sanitary hot water for collective housing, as known before the present invention; - Figure 3 illustrates a ventilation installation and production of sanitary hot water for collective housing, according to the present invention; and - Figures 4 to 8 illustrate embodiments of the invention according to optional improvements.
    For the sake of clarity, the dimensions of the elements which are represented in these figures do not correspond to real dimensions nor to actual dimension ratios. In addition, identical references which are indicated in different figures designate identical elements or which have identical functions. The exemplary embodiment of the invention which is illustrated in FIG. 3 is obtained in the following manner, from the installation of FIG. 2: each water heater 2X replaces the two water heaters 2XA and 2XB. Thus, the hot water outlet 7 of the water heater 2X is divided to serve the two housing XA and XB. In this sense, the water heater 2X is shared between the two housing XA and XB. Domestic hot water consumption meters, or energy meters associated with this consumption, can be installed on each division branch of the outlet 7, to determine the consumption of hot water or energy that take place separately. in housing XA and in housing XB. In the example shown, the installation comprises four water heaters 21-24 which are dedicated one-on-one levels of the collective housing 100, each water heater serving the two housing of the level at which it is located.
    In the installation example of FIG. 3, the air inlet of the evaporator 2 of the heat pump of the water heater 2X is connected to the air extraction lines 1XA and 1XB of the two housings XA. and XB. In this way, the distribution of the dwellings of the collective housing 100 for the supply of the hot water heaters coincides with the grouping of dwellings by water heaters for the hot water supply. Nevertheless, such a coincidence is not essential for the invention.
    The reference 101 designates the collective exhaust air duct which is connected upstream to the air outlets of the evaporators 2 of the water heater 2X, and which is connected downstream to the collection box 102. The duct 101 can be located in a technical sheath 110 which connects all the levels X of the collective dwelling 100. For example, the technical sheath 110 can be located in the respective levels X levels.
    Preferably, but in a way that is not mandatory, each water heater 2X can be located on the same floor as the housing XA and XB it supplies hot water. In particular, it can be installed inside the landing sheath 110. Such a location of each water heater 2X in a common part of the collective housing 100 has the following advantages: - the encroachment of the installation in the living space of each dwelling is reduced; - the noise nuisance that can be caused by the water heater for the occupants inside each dwelling is reduced; - maintenance of the water heater is easier and does not require access to the interior of housing; and - supplying the water heater with cold water, evacuation of water from the safety group of the water heater, evacuation of the condensates from its heat pump, provision of additional air intakes and / or provision downstream of the evaporator of the water heater, out of the air that is extracted from the housing, are facilitated.
    In general, sharing a single water heater between several homes can benefit from the abundance of hot water consumption that exists between these homes. Thus, the capacity of the water tank of the water heater that is shared may be less than the sum of the capacities of the water heater tanks that would be dedicated individually and separately to the dwellings.
    Because of sharing a same water heater between several dwellings, it may be preferable that the settings of the water heater are not accessible to the occupants of dwellings that are supplied with hot water by this water heater.
    It is understood that the following variants can be implemented in different installations which are all in accordance with the invention: - more than two separate housings can be supplied with hot water by the same water heater; - Houses that are supplied with hot water by the same water heater are not necessarily located at the same level X of the collective housing 100, nor necessarily located at the same level as the water heater; and - the design of the hot water supply of the dwellings of each level of the collective dwelling, from water heaters that are shared between several dwellings, may be different from one level to another.
    Figures 4 to 8 illustrate optional enhancements or adaptations, which are compatible with the invention. As an illustration, we consider the water heater 10 which supplies domestic hot water housing XA and XB.
    In the improvement of FIG. 4, the air inlet of the evaporator 2 of the water heater 10 can be connected to an additional air intake 121, in addition to the ducts 1XA and 1XB which come from the housings XA and XB. . 120 denotes an intermediate duct which connects the additional air intake 121 to the air inlet of the evaporator 2. The intermediate duct 120 may be provided with a damper 122 for adjusting the complementary air flow rate. is admitted by the additional air intake 121. For example, the additional air intake 121 may be located in a staircase column, or a basement level, or attic of the collective housing 100, for enjoy an air that has been heated without any cost to the occupants by the energy losses of the collective housing 100, or to benefit from additional flow without increasing the loss of housing. The placement of the water heater in a collective area of the dwelling 100 facilitates its connection to the additional area outlet 121, since it can be located in the immediate vicinity of the water heater in the same collective area. If the collective housing is equipped with such solar panels, the additional air intake 121 may also be located near these solar panels, where the air is heated by the panels themselves. It is thus possible to supplement the air flow rates that are extracted from the housings XA and XB when these flows are insufficient, and / or when the temperature of the air that is captured by the additional air intake 121 is adapted for a optimal operation of the heat pump. An insufficient air situation that is extracted from the housings XA and XB can occur especially when the air extraction vents 1XY which are located in the housing XA and XB are variable opening, for example hygro-adjustable or with modifiable opening by the occupants of these dwellings. Optionally, the register 122 may be slaved to the operation that is controlled for the heat pump, in an automated manner. In other words, the flow rate of the additional air intake 121 can be adjusted automatically to improve the coefficient of performance of the heat pump, whatever the operational states of the air intakes that are located in the housing.
    The improvement of Figure 5 is the opposite to a situation where the air flow rates that are extracted from the housing XA and XB can be high compared to the flow that is sufficient for the optimal operation of the heat pump. In this case, the transit through the heat pump of all the extracted air that is extracted unnecessarily causes a loss of aeraulic load, and a fouling of the heat pump. A bypass duct 123 can then be added between the inlet and the air outlet of the evaporator 2, so that all the air which is extracted from the housings XA and XB, or only a part of this air ( from 0 to 100%, terminals included), is transported by this bypass duct 123 without necessarily passing through the evaporator 2. Preferably, the bypass duct 123 may be provided with a register 124 in order to adjust the flow rate the air which is diverted from the evaporator 2. When the air extraction circuit is provided with a filter 125 upstream of the air inlet in the evaporator 2, then the inlet connection of the duct bypass 123 on the air extraction circuit is itself preferably located upstream of the filter 125. In this way, a fouling of the filter 125 can be reduced, compared to a configuration in which the whole of the air that is extracted from the XA and XB slots will traverse it the filter 125. Thus, when the heat pump is not in operation, the bypass air can be preferred to avoid unnecessary clogging.
    In the improvement of FIG. 6, the air extraction ducts 1XA and 1XB which come from the housings XA and XB are connected to the air intake of the evaporator 2 via a collection plenum. 130. The collection plenum 130 may be located in one of the housings XA or XB, but preferably in a common part of the collective dwelling 100. Possibly, it may be straddling the boundary between several dwellings, or between one of the housing and a common part of the collective dwelling 100. Optionally also, the use of the additional air intake 121 can be combined with the plenum 130. In this case, the intermediate duct 120 connects the intake of additional air 121 at plenum 130.
    The improvement of Figure 7 relates to the case where the air extraction circuit is provided with a filter 125 upstream of the evaporator 2 of the water heater 10. Such a filter 125 protects the evaporator 2 against risks progressive obstruction. Because of its gradual fouling, the filter 125 can cause a reduction in the air flow through the evaporator 2, and therefore prevent optimal operation thereof. It is then advantageous to provide a pressure sensor 126 upstream of the filter 125 in the direction of flow of the air. The speed of the motorized ventilation unit 103 can then be adjusted according to the pressure measurement signal produced by this sensor 126, so that the evaporator 2 is traversed by an optimal air flow, or at least sufficient . This pressure measurement signal may be analog or binary with respect to a predetermined pressure threshold, for example to indicate that the pressure upstream of the filter is sufficient, and / or that sufficient ventilation of the housing is obtained. For this, a control unit 127, denoted CTRL, can be connected to convert the pressure measurement signal produced by the sensor 126 into a control signal which is transmitted to the motor 128, denoted M, of the unit 103. When several water heaters of the collective housing 100 are thus provided with air filters 125 upstream of their respective evaporators 2, and respective pressure sensors 126, while the air outlets of the evaporators 2 are connected downstream to the same collection box 102 with the motorized ventilation unit 103, then all the pressure sensors 126 can be connected to the same control unit 127. This unit 127 can then adjust the speed of the motorized ventilation 103 so that all the evaporators 2 of the water heaters concerned are traversed by sufficient airflows. In other words, the control unit 127 can adjust the speed of the motorized ventilation unit 103 as a function of that of the air flow rates in the evaporators 2 which would appear to be insufficient first.
    In an alternative embodiment of this improvement, each water heater whose evaporator 2 is supplied with air through a filter 125 may comprise an individual motorized ventilation unit 8, internal to this water heater (see Figure 1). In this case, the control unit 127 adjusts the speed of this individual motorized ventilation unit 8 according to the pressure measurement signal produced by the pressure sensor 126 located upstream of the evaporator 2 of the water heater. corresponding, and upstream of the corresponding filter 125.
    The improvement of Figure 8 can be applied to each water heater 10 which is used in an installation according to the invention. Its purpose is to preheat the supply water of the water heater 10, before this water is introduced into the tank 1. For this, a heat exchanger 140 is arranged between a sewage drain pipe 141 of the collective housing 100 and the supply line of the water heater 10 in cold water, which leads to the supply inlet 6. The sewage pipe 141 relates to the water of sinks, showers , etc., and is called gray water evacuation pipe, in the jargon of the skilled person. The exchanger 140 makes it possible to recover heat from the wastewater to preheat the cold water supplying the tank 1. It can be individual or collective, but it is preferably arranged on the wastewater evacuation of those of the dwellings which are served in hot water by the water heater 10, so that the water filling of the tank of the water heater coincides with the heat exchange from the waste water. This preheating reduces the final heating which is carried out inside the tank 1 to bring the water to a predetermined set temperature. Since the wastewater is routinely passed through a collective housing of the dwelling, the recovery of heat from the wastewater is facilitated by the placement of the water heater near this duct. Other adaptations of a ventilation and hot water production installation according to the invention are possible. For example, when each thermodynamic water heater 10 individually comprises a motorized ventilation unit 8 which is internal to this water heater, then the air that is extracted from the housing can be rejected outside near the outlet of the water heater. evaporator 2 of the water heater 10 without a collective exhaust air duct being used to collect the air coming from the evaporators of several water heaters 10.
