Description

Module for Suction and Delivery of a Fluid and Treatment System for the Associated Fluid The invention relates to a suction and delivery module for a fluid, in particular the water of a swimming pool or more generally of a pool and a system for treating said associated fluid. The invention relates more particularly, but without limitation, to a pool water heating system using a heat pump (hereinafter PAC). The treatment of a fluid can be understood as heating, cooling, filtration, the addition of chemical elements such as chlorine or any other action. Fluid means any type of low compressible fluids, commonly called liquids, such as fresh water, salt water, wine, fruit juice or beer. The term "pool" applies to a pool or more generally any type of container regardless of its size, such as an aquarium, a drum, etc. As a preferred application, we will describe a swimming pool heating system using a heat pump according to the invention.

Equipping a pool or pond with a heating device requires a generally complex installation to route electricity and especially water between the heat pump and the pond. In most cases, the layout and the geometry of the basins have a role to play in this installation. It is therefore necessary to use a specialized technician and make arrangements near the pool to camouflage and route water pipes from the basin to the CAP in particular. Currently, the methods of connecting the PAC for swimming pools consist in setting up a system of generally rigid pipes requiring welds to interconnect a heat pump, a hydraulic circuit, a filtration pump and a basin of which it is desired to temper the water. Other parameters are to be taken into account such as the distance between the basin and the CAP, the obstacles that may be between these two devices or even the environment around the heat pump.

This installation is a matter of specialists because it requires special technical knowledge and adapted tools. In addition, it generally requires a certain amount of time: three to four hours are usually required to complete an installation. It is thus relatively difficult for a pond owner to execute this implementation alone. Faced with these major difficulties and to save time and money, some manufacturers have developed installation kits for PAC. Although bringing a gain in autonomy for owners of such equipment, the commissioning of the facility often remains unclear, sometimes even tedious or prohibitive. In addition, the improper installation of the heat pump may lead to the risk of damaging the heat pump. In fact, the operation of the heat pump is prohibited without water circulation, since if the water does not circulate inside the heat pump, some components of it, such as the compressor or the titanium heat exchanger, can "burn", making the cap unusable. As shown in FIG. 1, a known exemplary embodiment consists in providing a treatment system for a tank 2, in a non-limiting manner, a heater, comprising a heat pump 1, a hydraulic circulation pump 3 which generates the flow and the flow of fluid, connected by two pipes, respectively the outlet ducts 4 and fluid inlet 5, to a suction module and discharge 6 immersed in the basin 2. The fluid is fed from the basin 2 to the cap via a suction port 7 which cooperates with the outlet duct 4. After being heated, said fluid is rerouted to the tank 2 via the inlet duct 5 which cooperates with the discharge mouth 8. Said mouths suction 7 and discharge 8 are positioned on a generally rigid casing 9, forming the casing of the suction and delivery module 6. To allow installation of said stable and durable module 6 near the basin 2, means of fi 10 are generally provided on said envelope 9. This module 6 is discrete and convenient to position on the edge of a basin, since it is of a relatively small size. This type of module 6 allows easy installation because the latter does not require any specific tool and can be done independently by any owner of a pool for example. In addition, the suction and delivery module 6 also offers a great adaptability to configurations of tanks 2, sometimes very varied, and remains independent of filtration. The use of such an installation device for PAC also makes it possible to facilitate the wintering operation: the suction and delivery module 6 and the outlet 4 and fluid inlet ducts 5 can be easily removed, only PAC 1 remains on site. About fifteen minutes are enough to deploy or remove the equipment.

However, this type of suction and discharge module is currently dedicated to specific PAC models and is not interoperable with most of the market PACs. It is thus necessary to purchase the appropriate suction and discharge module according to a particular PAC, which can generate significant costs and forces the owner of a pool in his choice of equipment. In addition, as already mentioned above, in order not to damage the installation, the commissioning of the heat pump requires the supply of pressurized water to feed during the first minutes the compressor of the heat pump, then the fluid inlet and outlet ducts of the hydraulic circuit are filled with air. It is therefore necessary to have a pressurized water supply W near the suction and discharge module or even the heat pump or to use an additional hose (of the garden hose type) to deliver water. the water in pressure during the commissioning of the system. It is also necessary to provide a valve or a bypass to connect at first, then disconnect in a second time said additional pipe. The owner of the basin must therefore proceed with a commissioning sometimes laborious to unroll a garden hose, put water in the installation manually, operate the heat pump and then put away the pipe once the commissioning has been completed. In addition, forgetting this initial phase or flooding under imperfect pressure can irreparably damage the module of the PAC. Indeed, the CAP is composed of four essential elements: an external heat exchanger also called evaporator which recovers calories in the outside air and makes them pass through the so-called "coolant" fluid; a compressor that compresses the heat transfer fluid, causing the temperature of the coolant to rise and thus increases the number of calories transported; an indoor exchanger or condenser that transfers all the calories recovered in the outdoor air and produced at the compressor to the heating circuit and finally a pressure reducer that lowers the pressure of the fluid to start a new cycle.E refrigerant or refrigerant Also called heat transfer fluid allows to pass free calories recovered outside and calories produced at the compressor to supply heat to the heating circuit. If no fluid flows in said compressor, it can overheat, causing its destruction. The CAP becomes unusable. Given the cost of replacing the compressor, it is not even repairable. In addition, the water supply pressure is not always possible depending on the facilities. Not all pools are initially designed to have a heater. It can be very difficult to integrate such a device on the hydraulic circuits of the basins after delivery. The invention makes it possible to meet the majority of the drawbacks raised by the known techniques and responds to the challenges raised above. It aims to provide a simple and fast installation device, inexpensive, removable and adaptable to any type of pools or fluids. To this end, the invention consists in providing a suction and discharge module for a fluid comprising a suction mouth cooperating with a proximal portion of a fluid outlet duct and a delivery port cooperating with a proximal portion of a fluid inlet conduit.

To facilitate the installation and commissioning of the fluid treatment system of a basin, generate a sufficient fluid flow, reduce the number of equipment and prevent damage to the processing means and more particularly, a pump With heat and its compressor, a suction and discharge module according to the invention further comprises a self-priming pump cooperating with the fluid outlet conduit downstream of the suction mouth.

To minimize any risk of electrocution resulting from an interaction between the fluid and the power supply of the pump "self-priming", it can be a low voltage pump. Advantageously, the "self-priming" pump 15 is a well pump or a cellar pump. In order to maintain the various elements of the module, but also to allow its removal, the module may comprise a first envelope having orifices arranged so that the respective proximal portions 20 of the inlet and outlet ducts open from said orifices. Advantageously, the suction mouth is positioned on the lower part of the first envelope, intended to be immersed to allow direct and permanent contact with the fluid. Preferably, the first envelope of said module can contain the self-priming pump to allow a simple and fast installation, a removable device and adaptable to any type of basins. According to another embodiment, the module comprises means arranged to ensure the floating of said mobile while maintaining the lower part of the first submerged envelope.

According to one embodiment, the module comprises a ballast sufficient to cause its immersion. In the case where an outer envelope contains the first envelope, as well as the discharge and suction mouths, the outer envelope may include an opening to allow fluid exchange between the outside world and the first envelope. In order to ensure a simple adaptation to any type of basin, the first envelope or the over-envelope of said module may be in an inverted "L" angled shape arranged to fit for example the edge or the lip of a basin. Although the module is designed to be removable, it may include fastening means for a durable installation at the edge of the basin. Advantageously, the respective proximal portions of the inlet and outlet ducts are flush with the orifices of the first casing. In order to prevent the suction of sheets, particles or any other body contained in the basin and to avoid blocking or hindering the operation of the self-priming pump of the suction and delivery module, the suction opening may comprise not limiting a strainer or a grid. Advantageously, the module may comprise means for moving the discharge mouth away from the suction mouth and thus make it possible not to suck up immediately a volume of previously heated fluid. Thus, the temperature of a pool can be tempered more rapidly. In order to allow, for example, the creation of a stream of hot water within the basin and to ensure a better propagation of the hot water, the means for moving the discharge mouth away can be arranged to maintain the discharge mouth at a depth greater than that of the suction mouth. In order to facilitate connections to any type of processing means, the respective distal portions of the input and output conduits of the module may include universal connectors. To simplify the handling of the suction and delivery module and its installation, the module may comprise gripping means. According to a second object, the invention relates to a system for treating a fluid of a basin, comprising means for treating said fluid, a suction / discharge module 15 according to the first subject of the invention, said means for treatment cooperating with the respective distal portions of the inlet and outlet ducts of said module. Advantageously, the fluid treatment means of the system may comprise means for supplying and / or actuating the "self-priming" pump. According to a preferred application, the treatment means may comprise filtration means. Alternatively or additionally, the processing means 25 may comprise heating means, in particular a heat pump. Preferably, the means for supplying and / or actuating the self-priming pump of the suction and discharge module are arranged to actuate the "self-priming" pump prior to the treatment means. To allow the connection of the treatment system to any type of processing means, the invention, according to a third object, relates to a method for adapting the processing means to the fluid treatment system according to the invention, comprising a step for adapting the fluid treatment means by adding to them means for supplying and actuating the "self-priming" pump of the suction and delivery module, said means actuating said pump prior to the treatment as such of the fluid during the putting into service of the means of treatment.

Other features and advantages will emerge more clearly on reading the description which follows and on examining the figures which accompany it, among which: FIG. 1 (already described) is a schematic representation of a known heating system . FIGS. 2A, 2B and 2C show different external views of a first embodiment of a suction and discharge module according to the invention; FIG. 3 depicts an internal view of a first embodiment of a suction and discharge module according to the invention; - Figure 4 describes a second embodiment of a suction module and discharge according to the invention; FIG. 5 is a schematic representation of an embodiment of a fluid treatment system of a basin according to the invention.

FIGS. 2A to 2C and 3 describe a first embodiment of the suction and delivery module 6 according to the invention.

Such a module comprises, like the suction and delivery module 6 described in connection with FIG. 1, a first casing 9 on which suction and delivery outlets 7 and 8 are positioned. In particular embodiment, the suction and discharge module 6 may comprise a plurality of suction mouths 7 and / or a plurality of discharge mouths 8. The presence of a plurality of suction mouths 7 makes it possible to maintain a capacity 10 in the event that one of the suction mouths 7 is obstructed. In addition, the presence of a plurality of discharge ports 8 provides a discharge of the fluid in several directions resulting in a faster and more efficient spread of the treated fluid. The first envelope 9 may be advantageously rigid or flexible. Preferably, it is made of a material resistant to corrosion, such as stainless steels, plastic materials and more particularly polypropylene or polytetrafluoroethylene (PTFE). The first casing 9 maintains the various elements of the suction and discharge module 6 together. It also gives the module 6 great adaptability and removability. Preferably, the first envelope 9 is in an inverted "L" angled shape arranged to fit the rim, the lip or the periphery of a basin containing the fluid that it is desired to treat, for example to heat. Advantageously, the first envelope 9 comprises fastening means 10 allowing a durable installation of the module 6 near the basin. These fixing means may be, without limitation, spacers, screws, suction cups, support pads or any other means of the same type providing permanent fixation or not. The first envelope 9 may also comprise universal connectors 11 making it possible to connect the distal portions of the inlet and outlet conduits 4 and 4 of the suction and delivery module 6 to any type of processing means, for example any PAC. . The presence of the universal connectors 11 ensures the interoperability of said module.

The first envelope 9 may also include gripping means (not shown in the figures) to facilitate the handling and installation of said suction module and discharge 6. These gripping means may be for example in the form of a handle, a handle, a shaft or a lever. A suction mouth 8 according to the invention may comprise a strainer or a grid: over time, the basins can collect particles, or corpuscles of different kinds, such as fragments of dead leaves, dust deposits, or piles of soil in the pools. The presence of the strainer or grid plays a protective role: to avoid the aspiration of said particles and consequently, to prevent blocking or interfering with the operation of the "self-priming" pump. In addition, in order to stop the particles that the strainer would pass, especially the sludge and fine herbs, an additional filter can be interposed between the strainer and the pump inlet. For example, the fast silica filter is particularly suitable for treating pool water. The strainer and the filter can be fixed permanently or not. In the case where the strainer and the filter are removable, the cleaning and maintenance of the module 6 and its suction mouth 7 are facilitated. According to another variant (not shown graphically), the suction and delivery module 6 comprises an overwrap enveloping the first casing 9, the suction and delivery outlets 7 and 8, the "self-priming" pump being at within the first envelope 9. To allow fluid exchange between the outside world and the first envelope, the outer envelope comprises one or more openings. These openings allow the suction ports 7 and discharge 8 to generate a flow of fluid to be treated via the one or more openings. Several advantages may justify such an arrangement: the presence of the over-envelope provides increased safety vis-à-vis the protection of children. Indeed, if some children play with the suction module and delivery 6, they can for example get caught in the fingers suction mouth 7, which can cause injury. On the other hand, the over-envelope may be present for aesthetic purposes or for personalization purposes, customization of said module 6.

Figure 3, in conjunction with Figures 2A-2C, provides an internal view of the first preferred embodiment. The first casing 9 of the suction and delivery module 6 includes a "self-priming" pump 12 cooperating with a fluid outlet duct 4 downstream of the suction port 7. The presence of this self-priming pump 12 allows in particular to reduce the number of elements required in the treatment system.

It also simplifies the installation and commissioning of such a system since the "self-priming" pump 12 allows the generation of a flow and an automatic fluid flow.

By "self-priming pump" means any pump equipped with an automatic mechanism that facilitates priming and therefore the pump start. Indeed, the pump body is arranged in such a way that a vortex is created, this vortex generating a depression in the suction mouth and thus a rising water. This type of pump does not require pre-filling or third-party supply of fluid by an additional conduit. The invention greatly simplifies the installation and commissioning of a treatment system comprising such a suction and delivery module 6. As soon as the self-priming pump 12 is connected to a fluid, it can operate. By way of example, the "self-priming" pump 12 may be submerged or submersible, the latter being characterized by its sealed motor immersed in the liquid to be pumped. It can be in the form of a piston pump. It can also be in some cases a centrifugal pump. A centrifugal pump is a rotating machine that pumps a liquid by forcing it through a paddle wheel or a propeller called impeller, often improperly called a turbine. The air is sucked into the pump body due to the vacuum created by the moving turbine. This air mixes with the liquid in the body of the pump. The air-liquid mixture is pushed towards the discharge where the lighter air separates from the heavier liquid, which returns to the turbine through the reinforcement channel. After removing all air from the intake manifold, the pump is primed and operates as a conventional centrifugal pump.

Advantageously, the "self-priming" pump 12 is a well pump or a cellar pump. The purpose of well pumps is to recover the fluid located below in the basin. The hydraulic part of the pump is always immersed, while its motor part is either connected to the wheel by a shaft one to five meters long, or made waterproof and submerged. The flow rate of said well pump is of the order of 3.5 m 3 / h. This flow rate of the order of 3.5 m3 / h is relevant for treating a fluid, for example heating the water of a swimming pool. Thus, no other element is necessary, apart from the PAC and the suction and discharge module 6. The vacuum cell pumps can also be used since they are functional from the moment it is placed in a sufficient level water, which is the case when immersed in a pond. The "self-priming" pump 12 is positioned downstream of the suction mouth 7, preferably on the underside of the casing 9, in direct connection with said suction mouth 7 to allow direct and permanent fluid exchange. between the fluid and the pump "self-priming" 12. In addition, the "self-priming pump" 12 can cooperate with the outlet conduit 4 of fluid in different ways: they may be, but not limited to, screwed, sealed or glued together, a fitting may also be present. This cooperation can be done permanently or not so as to ensure the maintenance of the outlet duct 4 and the self-priming pump 12 if necessary.

The suction and delivery module 6 also comprises an inlet duct 5 cooperating with the discharge mouth 8, which allow the redirection of the treated fluid in the basin. The discharge mouth 8 and the fluid inlet duct 5 are for example connected via a collar, screwed, glued or connected by any other means. According to the arrangement of the first casing 9, this can serve as an internal discharge duct, that is to say an internal fluid inlet duct 5. Advantageously, the suction ports 7 and discharge 8 are not positioned on the same plane in order to avoid the suction of the already treated fluid and to ensure the propagation of the treated fluid with respect to the rest. Preferably, the suction 7 and discharge 8 mouths are positioned relative to each other with an angle of 900. To prevent any risk of electrification or electrocution, the "self-priming" pump 12 that comprises a module 6 according to the invention is a low voltage pump. The available energy present in all homes is usually a "conventional" voltage of 230V or 110V. Elements in the immediate vicinity of a pool or even immersed in said basin, for example cables or a pump, connected to such electrical energy present risks of electrocution or electrification for anyone near the pool. To cope with this drawback, a 12V low voltage pump will advantageously be used as a "self-priming" pump 12. To supply the low voltage pump from the electrical network or via a third device, such as processing means a transformer is connected to the electrical network and supplies the pump 12 with the low voltage. The transformer will preferably be placed at a sufficiently distant distance from the basin designed to accommodate the suction and delivery module 6 to avoid any interaction between the fluid contained in the basin and the power supply of the transformer. FIG. 4 describes an alternative embodiment (with regard to that previously described in connection with FIGS. 2A to 2C and 3). Such a suction and discharge module according to the invention comprises means arranged to ensure the floating of said module. In accordance with FIG. 4 and as specified above in relation to FIGS. 2 and 3, the suction and delivery module 6 comprises a first casing 9 on which suction and delivery outlets 7 and 8 are positioned and within which are the "self-priming" pump 12 which cooperates with the fluid outlet duct 4 downstream of the suction mouth, and the fluid inlet duct 5 which cooperates with the discharge mouth 8. The first envelope 9 has two parts, one upper S, and the other lower I, the latter being intended to be kept immersed. The "self-priming" pump 12 will preferably be placed in the lower part I of said first casing 9. Reliable and permanent fluid exchanges are guaranteed with said pump 12. To maintain the suction and delivery module 6 on the surface of the casing a basin, said module 6 further comprises floating means 13, which can be arranged within the first envelope 9 or outside said first envelope 9. Preferably, said floating means 13 will be positioned at a distance from depth lower than that of the "self-priming" pump 12. A waterline is defined by the floating means 13: advantageously, the suction mouth 7 is positioned below the waterline. Floating means 13 may be buoys or floats generally hollow inflated with air or a neutral gas such as helium or neon. They may also be filled with a less dense solid material than water such as hydrophobic polystyrene foam. The floating means 13 allow the suction and delivery module 6 to move to the surface of the basin and thus to obtain a better distribution of the treated fluid.

According to a third embodiment (not shown graphically), in place of the floating means 13, a suction and discharge module 6 according to the invention may comprise a ballast sufficient to cause the immersion of said module 6. ballast moves the center of gravity or increases the mass of the suction and delivery module 6 to cause immersion of said module. The ballast may be of different types: the material constituting the first envelope 9 acts as ballast, that is to say that this material is denser than the fluid to be treated. For example, in the case of water, the envelope may be composed of one or more metals, such as lead, stainless steel or an alloy of different metals. Alternatively, the floating means may be replaced by weighting means: for example, the buoys or floats may be substituted by small bags of lead or shot. According to a fourth embodiment (not shown graphically), the suction and discharge module 6 can comprise means for moving the discharge mouth 8 away from the suction mouth 7. These means can be arranged to further maintain the discharge mouth 8 to a depth greater than that of the suction mouth 7. For example, these means may consist of one or more flexible tubes or not, an arm or a horn. They can cooperate with the discharge mouth 8 in different ways: they can be screwed, glued, or sealed, permanently or not. According to one configuration, they make it possible to move the discharge mouth 8 towards the bottom of the basin and thus, if this treatment consists in heating the fluid of a basin, to create a stream of hot fluid towards the bottom of the basin while the mouth 7, closer to the fluid surface, can cause the fluid to be heated to a PAC. The heating is therefore more efficient and faster. Alternatively, the fluid inlet duct 5 can open out of the discharge mouth 8, replacing the various means to move the discharge mouth 8 away from the suction mouth 7. The distal portion of the means for moving the mouth away from delivery 8 of the suction mouth 7 may include a ballast if the latter are substantially flexible to direct the discharge of the fluid to the bottom of the basin. FIG. 5 represents an embodiment of the treatment system according to the invention. By way of non-limiting example, the treatment consists in heating the water of a pool with the aid of a PAC. This PAC could be substituted by an electrical resistance, a solar heating or any other equivalent means. In another variant, the processing means may comprise filtration means. The treatment system comprises a heat pump 1, a suction and discharge module 6 according to the invention, said heat pump 1 cooperating with the respective distal portions of the inlet and outlet ducts 4 and 4 of said suction and exhaust module. The distal portions of the inlet and outlet ducts 4 and the cap may cooperate in different ways: by way of nonlimiting examples they may be screwed, glued or sealed together. Preferably, the suction and discharge module 6 comprises universal connectors 11 which can be in the form of a socket. The universal connectors 11 make it possible to easily connect the suction and discharge module 6 to any type of heat pump 1. The "self-priming" pump 12 is electrically powered by the heat pump 1, which also controls its operation: the heat pump 1 first control the pump 15 "self-priming" 12 causing the impoundment of the installation, then a few moments later (a few seconds or tens of seconds for example), it triggers the start of its compressor without risk for installation. A transformer 14 is present in the system to allow the passage of high voltage 230V to low voltage 12V to supply the self-priming pump. For this, the invention provides that the processing means comprise means for supplying and / or actuating the "self-priming" pump 12. By way of non-limiting example, in the context of a heating system with using a heat pump, the "self-priming" pump is powered and / or controlled by the heat pump 1 by means of a servo terminal block generally named P1 / P2 and the control panel, also called interface This type of servo terminal block P1 / P2 is present on any recent or modern PAC in order to possibly connect and control one or more auxiliary pumps. Thus the heating system does not require adaptation of the heat pump 1 to connect the suction and discharge module 6 intended to be immersed in the basin, in the case where the heat pump comprises the servo terminal block P1 / P2. According to the invention, as soon as a heating setpoint is delivered via the setpoint interface of the capacitor 1, the latter firstly activates a servocontrol system, corresponding to the P1 / P2 type terminal block, which triggers the "self-priming" pump 12 of the suction and delivery module 6, then after a predetermined or configurable time, generally from a few seconds to a few minutes, the compressor of the heat pump 1. This delay is sufficient for the pump " self-priming "suction and discharge module (6) feeds the fluid installation, including the compressor of the PAC 1. Thus, the compressor or the PAC in general are preserved. This delay can be adjusted to take into account the length of the inlet ducts 5 and fluid outlet 4 cooperating with the suction and discharge module 6 and the PAC 1 in particular. As a variant, the heat pump may additionally comprise a flow sensor making it possible to determine the presence of a fluid or not in the compressor to ensure its commissioning and that of the heat pump 1 in general. The invention also provides a method of adapting the heating system to a PAC of an old type, that is to say not having a servo-control system of auxiliary pumps, whether it is a terminal block d servo P1 / P2 or any other equivalent means. In this case, the invention envisages an adaptation of the means for treating the fluid by adding to them means for supplying and actuating the "self-priming" pump 12 of the suction and delivery module 6, said means actuating said pump beforehand. treatment as such of the fluid during the putting into service of the processing means. By way of non-limiting example, these means for supplying and actuating the "self-priming" pump may be in the form of an additional electronic control unit arranged, for a first time, to supply and actuate the "self-priming" pump. - priming »12 of the suction / discharge module 6 and in a second step, that is to say after a predetermined or configurable time, control the compressor of the PAC. This housing can be integrated in the heat pump or intercalated between the setpoint interface and the heat pump 1. It makes it possible to connect the suction and delivery module 6 to any type of heat pump or more generally any type of treatment. To allow the connection of the treatment system to any type of processing means, the invention, according to a third object, relates to a method for adapting the processing means to the fluid treatment system according to the invention, comprising a step for adapting the fluid treatment means by adding to them means for supplying and actuating the "self-priming" pump of the suction and delivery module, said means actuating said pump prior to the treatment as such of the fluid during the putting into service of the means of treatment.

The invention has been described when it is implemented with a heat pump for heating the water of a swimming pool. However, it can be used with other types of heating device, especially with a device comprising an electrical resistance or other types of treatment, more particularly devices for filtration, cooling or addition of chemical elements. It can also be used for other types of fluids, such as wine, and other types of ponds such as aquariums, vats and barrels. It could also be envisaged that a plurality of suction and discharge modules would be connected to a treatment system to improve the efficiency of the assembly. Other modifications may be envisaged without departing from the scope of the present invention defined by the appended claims.
