Description

DESCRIPTION

Installation comprising elements for pumping and heating the water of a swimming pool, which forms a compact chamber placed above the ground.

The present invention relates to a heating and water treatment installation, intended in particular for the water in a pool.

Small pools, particularly private pools, need various water treatment materials.

Generally, a pumping group that pumps the pool water is circulated to circulate it in a filter, formed by a reserve of sand or a filter cartridge, before returning it to this 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 rate "pH" that characterizes the level of acidity. In particular it can be carried out continuously, for example, in the flow of water pumped for filtration, pH measurement, as well as the addition of the products that correct it if necessary.

On the other hand, it is known, for the heating of these pools, to use a heat pump comprising an evaporator that receives the calories from the ambient air that constitutes the hot source, and a condenser that dissipates calories in the pool water to reheat it , which is put into circulation by the pumping group.

To protect these different materials and to give the contour of the pool a clean and pleasant appearance, an existing shelter is used in the vicinity or one is built, to form a technical room that receives these equipment. The heat pump can form an independent module that remains outside, which specifically facilitates the circulation of the surrounding air necessary for the operation of the evaporator. These various outdoor installations represent a busy volume and carry costs.

On the other hand, a known device, presented specifically by document FR-A1-2987387, comprises a chamber that has a lower part intended to be buried, comprising, below ground level, splices of water flows intended to be connected directly to pipes buried, which lead specifically to the pool.

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

However, this device involves several problems. In particular, the partially buried chamber needs an excavation of the soil to form a cavity that receives this buried part, and to form trenches that allow the pipes that are spliced in the buried part to be put underground. The joints to the pipes are not easily accessible. In addition, since the chamber has a lower part disposed underground, in case of entry of water into the interior from, for example, condensation, a flow of rainwater, or an escape from the water circulation of the pool, its evacuation is difficult to perform. On the other hand, thermal exchanges to the outside, and inside the chamber, are not optimized.

The present invention specifically aims to avoid these disadvantages of the prior art.

To this end, it proposes a heating and water treatment installation, in particular for the water in a pool, which comprises a water circulation pump that feeds filtration means with this water, and a heat pump, this installation being notable because it comprises a chamber intended to be placed completely above the ground outside the buildings, this chamber containing all the equipment comprising the circulation pump, the water filtration means, the heat pump comprising an evaporator which is arranged directly on an outer face of the chamber, and splices above the ground towards external pipes for water circulation.

An advantage of this installation is that this chamber can be placed on the ground quickly and easily, without digging the floor for the chamber and the pipes, and splicing the external pipes that remain accessible at the bottom. When the chamber is above the ground, its different faces are completely clear, which allows an evaporator to be placed on these faces that has a large exchange surface with the ambient air, which improves the performance of the heat pump.

The heating and water treatment plant according to the invention may further comprise one or more of the following characteristics, which can be combined with each other. Advantageously, the splices of the external pipes run under the lower face of the chamber. The joints are then easily accessible between these different supports.

Advantageously, the chamber comprises a closed and ventilated compartment that receives the air flow through the evaporator, in which the circulation pump is located. Advantageously, the circulation pump comprises a turbine to cool its engine, which extracts the air that passes through the evaporator. The cooling of the circulation pump is improved by taking the refrigerated air that leaves the evaporator.

In particular, the air that passes through the evaporator can be extracted by the turbine through a sleeve that takes it into a closed intake compartment.

Advantageously, the installation comprises in the chamber some physicochemical water treatment means. Advantageously, the air extracted by the turbine of the circulation pump is expelled into a technical compartment comprising water treatment products. In this way this compartment is ventilated to avoid gas accumulations.

Advantageously, the water filtration means comprise a substantially cylindrical filter, arranged horizontally below a fan that is at the level of an opening of the upper face of the chamber, to activate the flow of air through the evaporator. This optimizes the use of space in the chamber.

Advantageously, the evaporator forms a panel that covers the faces of the chamber over its entire height. The dimensions of the chamber are maximized to have a large evaporator heat exchange surface, which optimizes its performance. Advantageously, the camera comprises drawers that slide horizontally, which the equipment receives. This reduces the space used on the faces of the camera for equipment that must remain accessible.

In particular, the chamber can comprise sliding drawers that receive an electric control housing of the flat arranged installation, or a tray for organizing treatment products. It facilitates, with little space on the facade, access to the housing, or the handling of heavy loads for the organization of products.

Advantageously, the chamber comprises at each corner a corner profile with a rounded section, arranged vertically, which has at its ends a horizontal fixing plate that is supported by a plate that forms the upper or lower face. In this way a rigid and appropriate assembly of the chamber is easily performed.

Other features and advantages will be apparent from the following description of the invention, given by way of example only, with respect to the accompanying drawings in which:

- Figure 1 is a view of the rear face and the right side face of a heating and water treatment installation 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 face of this installation, the drawer containing the treatment products and the drawer of the electrical panel being open;

- Figure 4 is a diagram from above of this installation;

- Figure 5 is a top view of the circulation pump of this installation that has an air hose that extracts the air in a compartment; Y

- Figure 6 is a detailed view of a corner profile of the chamber of this installation.

Figures 1, 2, 3 and 4 present a camera of globally parallelepipedic shape, formed by cut and folded sheets, comprising an upper face 2 and a lower face 4 connected to each other by four corner profiles 6. Each side of the upper 2 and lower faces 4 comprises, between the corner profiles 6, a flange formed by a vertical fold and then a horizontal fold directed towards the inside of the chamber, in order to constitute stiffening ribs of the contour of these sheets, which They also prevent injuries to people.

The lower face 4 rests on four feet 24 arranged in the corners, adjustable in height by means of an adjustment wheel easy to turn manually, which have a large support surface on the floor, which allows the camera to be placed directly on any floor at the same time which is maintained horizontally by these adjustments.

The upper face 2 comprises a large perforation covered by a grid 8, which forms an air outlet that protects an air extraction fan 84 below.

The chamber comprises a face called by agreement front face 10, which comprises control elements of the installation. Observing this front face, the chamber comprises a right side face 14 having an electric housing 20 as well as the water treatment products 22.

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

The four vertical faces 10, 12, 14, 16 of the chamber are outside an evaporator 70 disposed on the façade, normally closed by panels formed in a sheet, not shown in the figures, which guarantee protection, as well as an appropriate aesthetic of the set

The circulation of water in the chamber from a pool 18 arranged next to it is as follows. The chamber comprises four water suction joints 26 from the pool 18, arranged in parallel, leading vertically below the lower face 4, in the front right corner of this chamber. Each suction connection 26 has its own valve 28, allowing the suction to be adjusted at different points in the pool 18.

The chamber comprises a water return connection to the pool 18 and a water drain connection to a drain 42, arranged at the rear of the suction joints, which likewise flow vertically below the lower face 4.

The different external pipes 30 placed flat on the ground are connected in the joints 26 by means of couplings that come under the chamber, between the feet 24. These connections are easily made by free access to the pipes 30 and the joints 26 that are not buried, which facilitates disassembly or exchange of the entire chamber.

As a variant, the external pipes 30 can be buried in ditches to make them invisible, always making the connection with the chamber easily thanks to the joints 26 that are above the ground. Under the chamber, at the level of the valves, a register can be placed on the ground, which contains the outlet curvatures of the pipes that rise upwards.

The left part of the chamber containing a circulation pump 34, its prefilter 32, a main filter 40 and the evaporator 70, form a separate ventilation compartment 74, by means of a substantially watertight vertical partition 72, of the right part forming a technical compartment 76 containing an electrical housing 20 and water treatment products 22. The water circulation pump 34 comprising an electric motor arranged horizontally in the longitudinal direction, at the bottom and to the right of the ventilation compartment 74, pumps the water coming from the suction joints 26 through the cartridge prefilter 32, to return it through a first pipe 36 to a six position valve 38. The prefilter 32 allows to remove the coarsest 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 pipes to a cartridge filter 40 that forms a horizontally arranged cylinder, at the bottom on the left side of the ventilation compartment 74. The cartridge filter 40 comprises at its front end a cover Removable, easily accessible after depositing the front panel, which allows it to be opened to remove the cartridge and clean or replace it.

In a position of the valve 38 of normal operation of the installation, the water coming from the circulation pump 34 passes in the filter 40 in order to filter effectively, and then return to the second pipe 44. In a second position of this filter cleaning valve 38, the water passes in the reverse direction in this filter in order to clean it of its impurities, and then this charged water that passes through the valve is expelled by the drain connection 42 provided for connect to an external drain pipe. In this way, a washing of the filter 40 can be obtained simply and quickly with a few minutes of operation that allows the interventions to be spaced on its cartridge.

The valve 38 has a bypass position that avoids the filter 40, an emptying position of the pool that directly expels the water from the circulation pump 34 through the first pipe 36, towards the drain joint 42 to be eliminated, and a closing position that closes all pipes.

The water returned in the second pipe 44 arrives at a three-way valve 46 comprising manual and automatic controls, which distributes this flow to the heat pump 50 by a third pipe 48, and towards a water treatment unit 62 by means of a fourth pipe 64. The distribution is carried out specifically according to the heat heating capacity of the heat pump 50.

The heat pump 50 arranged in the right rear corner of the chamber comprises a compressor 52 driven by an electric motor, which generates a pressure in the internal cooling fluid at the level of a condenser 54 to obtain an exothermic condensation of this fluid. The calories are recovered by the flow of water from the third channel 48, which passes through the condenser 54, to re-exit through a fifth channel 60 in order to go to the water treatment unit 62.

Water leaving the water treatment unit 62 flies into the pool through an outlet junction 66.

The third 48 and fifth pipes 60 each have an isolation valve that allows the heat pump 50 to be isolated, particularly in winter when it is necessary to purge the entire circuit in case of risk of frost.

The heat pump 50 has an evaporator 70 which is a heat exchanger with the ambient air that receives the cooling fluid at a low pressure to allow evaporation. The evaporator 70 forms a flat panel arranged vertically over the entire height of the chamber, which covers approximately 80% of the rear face 12 of this chamber, and which returns by means of a fold over the left side face 16 to cover it approximately halfway . In this way, a large exchange surface with the ambient air is available using the entire height of the chamber, which a partially buried chamber cannot do.

The water treatment unit 62 may in particular comprise a salt electrolyzer and a pH regulator. Advantageously, the pH measurement is carried out in 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, which blows the air extracted vertically upwards, generates by suction through the evaporator 70 a flow of air from the outside to compensate This extraction. As a variant, the extraction fan can be arranged on a side face of the chamber, blowing the extracted air horizontally. In this way, a contribution of calories is made in the evaporator 70 from the hot source formed by the ambient air, allowing evaporation, as well as good ventilation of the ventilation compartment 74. Advantageously the cartridge filter 40 forming a cylinder horizontal is arranged under the air extraction fan 84, which optimizes the occupied volume of the assembly. The right end of the evaporator 70 extends to the right of the vertical partition 72, to form a small vertical triangular intake compartment 78 closed by the evaporator, the vertical partition and a complementary plate 80 that connects these two elements.

Figure 5 shows an air sleeve formed of plastic material 82, which comprises a transverse part that draws air in the closed intake compartment 78, by means of a perforation through the vertical partition 72, which, after a bend, is extended by means of a substantially circular longitudinal part 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 surrounding wings this engine in order to cool it, and then expel it into the technical chamber 76. This air flow is indicated by arrows A.

Through this combination of means, numerous advantages are obtained economically. The electric motor of the circulation pump 34 benefits from an air cooled by the evaporator 70, which is particularly interesting when the ambient temperature is high, to avoid causing it to heat and deteriorate prematurely. At the same time, by expelling this air flow to the technical compartment 76, it is vented, which prevents an accumulation of gases in this chamber from the vapors of the stored products, which, specifically for acidic or basic products, could cause corrosion of the sheets that form it.

In addition, the air hose 82 that surrounds the turbine and the circulation pump 34 with its engine, and which channels the air flow, reduces the noise emitted by these different elements.

The technical compartment 76 comprises in the upper part a drawer that slides transversely on casters, which receives the electric housing 20 arranged horizontally with the controls in the upper part. The electrical cables connected to the electrical housing 20 form on the side of the technical compartment 76 a loop arranged in a vertical plane, allowing the movement of this housing forward without applying effort on these cables.

The technical compartment 76 comprises at the bottom another drawer that slides transversely on casters, which receives the drums of treatment products 22.

In this way, simple, fast and easy access to the electrical housing 20 and the treatment products 22 is available, using a reduced facade surface. The drawers that slide on casters allow in particular to easily handle the drums of products that can be weighed.

The electrical housing 20 receives the current from an external electrical supply 86, and is 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 unit of water treatment 62. It can include various programmable automatisms, to carry out controls and operations automatically.

In particular, a remote control of the installation can be carried out, with a cable connection, by radio, specifically of the WiFi type, or by smartphone called in English Smartphone. Specifically, the installation can be connected to home automation control applications.

Particularly for frost, an outside temperature measuring probe is advantageously arranged connected to an electronic control, which, in case of too low temperature, activates the water flow by starting the circulation pump 34 to prevent the freezing of this water.

Figure 6 shows a corner profile 6 of constant section, formed in a pressed sheet comprising in the cross section a constant radius of approximately 5 cm, which gives the chamber a particular aesthetic appearance while avoiding injury risks With live edges.

Each side of the profile 6 comprises two successive inverted folds to return towards the center of the chamber and then to the side, to form a flat surface parallel to the side that receives a closing side panel from the sides of the chamber.

Each end of the profile 6 comprises a fixing plate 92 transversely welded, which follows the constant radius inside, as well as the edge given by the first fold. Each corner of the upper plate 2 comprises two perforations 94 that each receive a screw screwed into a threaded bore 96 of the fixing plate 92 that is slightly offset with respect to the end of the profile 6, in order to obtain a part Top plate that is level with this end. In this way, a simple and rigid assembly of the plates of the upper 2 and lower 4 faces connected to each other by means of the corner profiles 6 is obtained, while providing a sober and refined aesthetic.

In particular, the chamber containing the set of elements can form a compact system, which in this example has a width of 1.20 m, a depth of 0.90 m and a height of 0.60 m. Different materials can be used to make this chamber, such as galvanized steel, stainless steel, or plates coated with an epoxy coating, plastic materials, or wood.

In general, the installation according to the invention provides an interesting combination of different functions, specifically to optimize indoor air flows and heat exchanges, in order to form a compact module easy to install on the edge of a pool, and aesthetic.
