Description

INSTALLATION COMPRISING WATER PUMPING AND HEATING ELEMENTS OF A SWIMMING POOL, FORMING A COMPACT SUBSTATION UNDER GROUND

The present invention relates to a heating and water treatment plant, provided in particular for the water of a swimming pool.

Small pools, especially private pools, require several water treatment equipment.

There is usually a pumping unit that pumps the pool water to circulate in a filter, formed by a reserve of sand or a filter cartridge, before pushing back to the pool.

A water quality treatment is also carried out, for example with a salt electrolyzer to release chlorine, and a regulator of the hydrogen potential "pH" that characterizes the level of acidity. In particular one can carry out continuously, for example in the flow of water pumped for the filtration, the measurement of the pH as well as the addition of the products which correct it if necessary.

Moreover, it is known for heating these swimming pools, to use a heat pump comprising an evaporator which receives the calories from the ambient air constituting the hot source, and a condenser dissipating calories in the pool water for warm it, which is circulated by the pumping group.

To protect these different materials and give the pool area a clean and pleasant, we use an existing shelter nearby or we built one, to form a technical room receiving the equipment. The heat pump can form an independent module remaining outside, which facilitates in particular the circulation of ambient air around necessary for the operation of the evaporator. These various outdoor installations represent a congestion, and entail costs.

Furthermore, a known device, presented in particular in document FR-Al-2987387, comprises a box having a lower part intended to be buried, comprising below ground level water flow connections intended to be directly connected to pipelines. buried, leading in particular to the swimming pool.

The box comprises two compartments separated by a transverse wall, one containing the heat pump swept by the ambient air flow for the evaporator, and the other the water circulation pump of the swimming pool, a filter for this water, a salt electrolyzer and a pH regulator.

However this device poses several problems. In particular the partially buried caisson requires a digging of the ground to form a cavity receiving this buried part, and to form trenches for putting underground the pipes connecting to the buried part. The connections to the pipes are not easily accessible. In addition the box having a lower part disposed underground, in the event of entry of water inside, for example from condensation, a flow of rainwater, or a leakage from the circulation of water. water from the pool, its evacuation is difficult to achieve. In addition, the heat exchanges to the outside, and inside the box, are not optimized.

The present invention is intended to avoid these disadvantages of the prior art.

It proposes for this purpose a heating and water treatment plant, in particular for the water of a swimming pool, comprising a water circulation pump supplying means for filtering this water, and a heat pump. , this installation being remarkable in that it comprises a box to be placed entirely above ground outside buildings, this box containing all equipment including the circulation pump, the water filtration means , the heat pump having an evaporator which is disposed directly on an outer face of the box, and fittings above ground to external pipes for the circulation of water.

An advantage of this installation is that it can quickly and easily, without digging the soil for the box and pipes, put this box on the ground, and connect at the bottom of the outer pipes that remain accessible. The box being above the ground, its different faces are completely clear which allows to have on these faces an evaporator having a large exchange surface with the ambient air, which improves the efficiency of the heat pump. The heating and water treatment plant according to the invention may further comprise one or more of the following features, which may be combined with one another. Advantageously, the connections of the external pipes open under the underside of the box. The connections are then easily accessible between these different supports.

Advantageously, the box comprises a closed and ventilated compartment receiving the flow of air passing through the evaporator, in which the circulation pump is located. Advantageously, the circulation pump comprises a turbine for cooling its engine, drawing air passing through the evaporator. The cooling of the circulation pump is improved by taking the cooled air leaving the evaporator.

In particular the air passing through the evaporator can be taken by the turbine through a sleeve which takes it into a closed intake compartment.

Advantageously, the installation comprises in the box means for physicochemical treatment of water.

Advantageously, the air taken by the turbine of the circulation pump is discharged into a technical compartment comprising water treatment products. In this way, this compartment is ventilated to avoid gaseous accumulations.

Advantageously, the water filtration means comprise a substantially cylindrical filter, disposed horizontally under a fan located at an opening of the upper face of the box, to activate the flow of air through the evaporator. This optimizes the use of space in the box.

Advantageously, the evaporator forms a panel covering the faces of the box over their entire height. We take maximum advantage of the dimensions of the box to have a large heat exchange surface of the evaporator, which optimizes its performance. Advantageously, the box comprises drawers sliding horizontally, receiving equipment. This reduces the space used on the faces of the box for equipment to remain accessible.

In particular the box may include sliding drawers receiving an electrical control unit of the installation arranged flat, or a storage bin of treatment products. It facilitates with little space in the front access to the housing, or the maneuvering of heavy loads for storing products.

Advantageously, the box comprises in each corner a rounded section section section, disposed vertically, having at the ends a horizontal fixing plate receiving the support of a plate forming the upper or lower face. It is thus easy to achieve a rigid and clean mounting of the box. Other features and advantages will become apparent from the following description of the invention, given by way of example only, with reference to the accompanying drawings, in which: FIG. 1 is a view of the rear face and of the right lateral face a heating and water treatment plant according to the invention; Figure 2 is a view of the front face of this installation; Figure 3 is a view of the front face and the right side of this installation, the drawer containing the treatment products and the drawer of the electrical box being open; Figure 4 is a diagram in top view of this installation; Figure 5 is a top view of the circulation pump of this installation having an air sleeve collecting air in a compartment; and Figure 6 is a detail view of a corner profile of the box of this installation. FIGS. 1, 2, 3 and 4 show a box of generally parallelepiped shape, formed by cut and folded sheets, comprising an upper face 2 and a lower face 4 interconnected by four corner profiles 6. Each side of the faces upper 2 and lower 4 comprises between the corner profiles 6, a flange formed by a vertical fold and a horizontal fold facing the inside of the box, to form stiffening ribs of the contour of these sheets, which moreover avoid to hurt people.

The lower face 4 rests on four feet 24 arranged in the corners, adjustable in height by a wheel easy to turn by hand, having a large surface of support on the ground, which allow to place the box directly on any soil while keeping it horizontally by these settings.

The upper face 2 comprises a large bore covered by a grill 8, forming an air outlet protecting an exhaust fan 84 which is underneath.

The box comprises a face conventionally called front face 10, comprising control elements of the installation. By looking at this front face, the box comprises a right side face 14 having an electrical box 20 as well as the water treatment products 22.

By convention, the direction perpendicular to the front 10 and rear 12 faces is called the longitudinal direction, the parallel direction being called the transverse direction.

The four vertical faces 10, 12, 14, 16 of the box are outside an evaporator 70 arranged in front, normally closed by panels formed in a sheet, not shown in the figures, which provide protection and aesthetics clean of the whole.

The flow of water in the box from a pool 18 disposed next to it, is as follows. The box comprises four water suction connectors 26 from the pool 18, arranged in parallel, which open vertically below the lower face 4 in the right front corner of this box. Each suction connection 26 has its own valve 28, to regulate the aspirations in different points of the pool 18.

The box comprises a water discharge connection to the swimming pool 18 and a water discharge connection to a sewer 42, arranged behind the suction connections, which in the same manner open vertically below the lower face 4.

The various external pipes 30 laid flat on the ground, are connected to the fittings 26 by elbows coming from below the box, between the feet 24. These connections are easily made by the free access to the pipes 30 and fittings 26 which are not buried, which facilitates disassembly or exchange of the complete box.

Alternatively one can bury the outer pipes 30 in trenches to make them invisible, the connection with the box is always easily thanks to the fittings 26 which are above the ground. Under the box can be arranged at the valves a gaze disposed in the ground, containing the exit curvatures of pipes that go upwards.

The left part of the box containing a circulation pump 34, its pre-filter 32, a main filter 40 and the evaporator 70, form a ventilation compartment 74 separated by a vertical partition 72 substantially sealed, the right part forming a technical compartment 76 containing an electrical box 20 and water treatment products 22.

The water circulation pump 34 having an electric motor disposed horizontally in the longitudinal direction, at the bottom and right of the ventilation compartment 74, pumps the water coming from the suction connections 26 through the cartridge pre-filter 32 to discharge it through a first pipe 36 to a six-position valve 38. The pre-filter 32 eliminates the largest impurities from the water, in order to avoid damaging the pump 34.

The six-position valve 38 disposed on the front face 10 which makes it easily accessible, is connected by a second pipe 44 to the heating and water treatment system of the pool.

The six-position valve 38 is connected by two lines to a horizontally disposed cartridge filter 40 forming a cylinder, down on the left side of the ventilation compartment 74. The cartridge filter 40 has at its front end a removable cover, easily accessible after removal of the front panel, to open it to extract the cartridge and clean or change it.

In a position of the valve 38 of normal operation of the installation, the water coming from the circulation pump 34 passes through the filter 40 in order to be effectively filtered and then discharged towards the second pipe 44. In a second the position of this valve 38 for cleaning the filter 40, the water passes upside down in this filter to clean it of its impurities, then the charged water passing through the valve is rejected by the sewer connection 42 intended to be connected to an outdoor sewer line. This results in a simple and fast way with a few minutes of operation washing the filter 40 which allows space interventions on its cartridge.

The valve 38 has a shunt position which bypasses the filter 40, a draining position of the pool which directly discharges the water from the circulation pump 34 through the first pipe 36, to the sewer connection 42 to be eliminated, and a closed position that closes all the pipes. The water discharged into the second pipe 44 arrives in a three-way valve 46 comprising manual and automatic controls, which distributes this flow to the heat pump 50 through a third pipe 48, and to a water treatment unit 62 by a fourth pipe 64. The distribution is made in particular according to the heat-heating capacity of the heat pump 50.

The heat pump 50 disposed in the right rear corner of the box comprises a compressor 52 driven by an electric motor, which generates a pressure in the internal refrigerant fluid at a condenser 54 to obtain an exothermic condensation of the fluid. The calories are recovered by the flow of water from the third pipe 48, which passes through the condenser 54, to exit through a fifth pipe 60 to be directed to the water treatment unit 62. The water leaving the water treatment unit 62, returns to the pool via an outlet connector 66.

The third 48 and fifth pipe 60 each have an isolation valve which isolates the heat pump 50, especially in winter when it is necessary to purge the complete circuit in case of risk of freezing.

The heat pump 50 has an evaporator 70 which is a heat exchanger with the ambient air receiving the refrigerant at a low pressure to allow its evaporation. The evaporator 70 forms a flat panel disposed vertically over the entire height of the box, covering about 80% of the rear face 12 of this box, and which returns by a fold on the left side face 16 to cover it approximately halfway. In this way we have a large exchange surface with ambient air using the entire height of the box, which can not achieve a partially buried box. The water treatment unit 62 may comprise in particular a salt electrolyser and a pH regulator. Advantageously, the pH is measured on the second pipe 44, upstream of the three-way valve 46.

The air extraction fan 84 arranged horizontally in the ventilation compartment 74 under the outlet grille 8, blowing the extracted air vertically upwards, generates by its suction through the evaporator 70 a flow of air from outside to compensate for this extraction. Alternatively the exhaust fan may be disposed on a side face of the box, by blowing the extracted air horizontally. This provides a calorie intake on the evaporator 70 from the hot source formed by the ambient air, allowing evaporation, and good ventilation of the ventilation compartment 74. Advantageously the cartridge filter 40 forming a horizontal cylinder, is disposed below the exhaust air fan 84 which optimizes the overall size of the assembly. The right end of the evaporator 70 protrudes to the right of the vertical partition 72, to form a small vertical triangular inlet compartment 78 closed by the evaporator, the vertical partition and a complementary plate 80 connecting these two elements.

FIG. 5 shows an air-formed plastic sleeve 82, having a transverse section collecting air in the closed intake compartment 78, by drilling through the vertical partition 72, which after a bend is extended by a substantially circular longitudinal portion surrounding the electric motor of the circulation pump 34.

The rear face of the electric motor of the circulation pump 34 comprises a turbine driven directly by the shaft of this motor, which sucks in the sleeve 82 the cooled air after its passage through the evaporator 70, to propel it on the fins surrounding this engine to cool it, then reject it to the technical box 76. This air flow is indicated by the arrows A.

By this combination of means economically numerous advantages are obtained. The electric motor of the circulation pump 34 has an air cooled by the evaporator 70, which is particularly interesting when the ambient temperature is high, to avoid heating it and wear it prematurely. At the same time by rejecting this flow of air to the technical compartment 76 it is ventilated which avoids a gaseous accumulation in this box from the vapors of stored products, which in particular for acidic or basic products could cause corrosion of the sheets forming it .

In addition the air sleeve 82 surrounding the turbine and the circulation pump 34 with its engine, and channeling the air flow, reduces the noise emitted by these various elements.

The technical compartment 76 has in the upper part a drawer sliding transversely on wheels, receiving the electrical box 20 arranged horizontally with the controls on the top. The electrical cables connected to the electrical box 20 form on the side of the technical compartment 76, a loop disposed in a vertical plane allowing the movement of this housing forward without applying stress on these cables.

The technical compartment 76 has in the lower part another drawer sliding transversely on wheels, receiving the cans of treatment products 22.

In this way there is easy, fast and easy access to both the electrical box 20 and the treatment products 22, using a reduced facade surface. The drawers sliding on wheels allow in particular to easily handle the cans of products that can be heavy.

The electrical box 20 receiving the current of an external power supply 86, and connected with all the electrical equipment of the installation to supply and control them, in particular the heat pump 50, the circulation pump 34, the fan 84 and the water treatment unit 62. It may comprise various programmable automations, to carry out the controls and operations automatically.

In particular, it is possible to carry out a remote control of the installation, with a connection by cable, by radio, in particular of the Wifi type, or by smartphone called in English language Smartphone. In particular, the installation can be connected to home automation control applications of a house.

In particular for the gel, advantageously an external temperature measurement probe connected to an electronic control is available, which in case of too low temperature activates the water flow by starting the circulation pump 34 to prevent the freezing of this water.

FIG. 6 shows an angle profile 6 of constant section, formed in a curved sheet comprising in the cross-section a constant radius of approximately 5 cm, which gives a particular aesthetic appearance to the box while avoiding risks of injury to sharp edges.

Each side of the profile 6 has two successive inverted folds to return to the center of the box and then to the side, to form a flat surface parallel to the side receiving a side panel closing the sides of the box.

Each end of the profile 6 comprises a transversally welded mounting plate 92, which follows inside the constant radius, as well as the edge given by the first folding. Each corner of the upper plate 2 has two bores 94 each receiving a tight screw in a threaded hole 96 of the fixing plate 92 which is slightly offset relative to the end of the profile 6, in order to obtain a plate top which outcrop with this end. In this way we obtain a simple and rigid mounting plates 2 upper and lower 4 connected to each other by the corner profiles 6, while providing a sober and uncluttered aesthetics.

In particular the box containing all the elements can form a compact system, which has in this example a width of 1.20m, a depth of 0.90m and a height of 0.60m. Various materials can be used to make this box, such as galvanized steel sheets, stainless steel, or epoxy-coated sheets, plastic materials, or wood. Generally speaking, the installation according to the invention provides an interesting combination of different functions, in particular for optimizing the internal air flows and heat exchanges, in order to form a compact module that is easy to install at the edge of a swimming pool. and aesthetics.
