The field of the invention is that of the removal of condensates, implemented in systems producing condensates, particularly air-conditioning systems, cooling systems, ventilation systems or heating systems.
More particularly, the invention relates to the optimisation of the assembly and to the installation of condensate removal means in such systems.
The use of condensate removal pumps is a technique well known in many applications, among which air-conditioning systems, cooling systems, ventilation systems, heating systems, etc. The applicant, particularly, develops and markets various devices adapted to all situations and all needs.
In these various applications, a condensate removal system is used for detecting, suctioning and discharging the condensates towards a wastewater outlet.
Such a system therefore essentially comprises a pump, electronics for controlling the latter and a water level detector in a tank, generally included in a plastic shell to form an assembly of small size and often of shape adapted to a particular use. Indeed, it is generally desired that the overall size of the removal system is compact and adapted to the environment.
Thus, as illustrated in
Consequently, this approach requires developing a wide range of products, according to the available space, the pumping capacities, etc.
This approach makes seemingly easy maintenance possible, since in the event of a fault, the device simply needs to be replaced. However, this is expensive, and it is not possible, for example, to only replace a faulty detector.
It has sometimes been proposed, for certain installations, to place the detector at a distance from the pump, with a wired connection between the detector and the electronics of the pump. These removal systems are thus adapted to installations other than in an elbow.
However, this leads to the design of specific systems, and therefore to a multiplication of types of removal systems, on the basis of the shapes, of the possible installations, of the desired powers or flow rates, etc. This obviously introduces production and storage complexities, with manufacturers, distributors and installers.
In particular, one drawback of the current approach is the lack of optimisation of the maintenance. Currently, the tradesperson carrying out the installation and the maintenance of such installations, must have a wide variety as diversified as possible of the various types of systems that may exist on the market in order to adapt to each installation/maintenance configuration. This represents a cost and a substantial storage volume, as well as a loss of time for the tradesperson.
From the point of view of industrialisation, the current solutions induce a multiplication of references and therefore a complex stock management (each configuration having its own electronic board, its own casing, its own packaging, etc.), a substantial production time, as well as difficulty in upgrading the product since any upgrade of a part thereof induces a reorganisation of the entire production chain.
Therefore, there is a need to simplify the industrialisation, installation and maintenance of condensate removal systems.
An aspect of the present disclosure relates to a condensate removal system comprising at least three independent modules:
Thus, the invention is based on a modular approach for facilitating the installation by offering an installation versatility based on three basic modules. Based on three modules, it is possible to implement various configurations.
This also makes it possible to optimise the maintenance that may only be partial (changing a single module and not the complete product).
Moreover, from the point of view of industrialisation, this makes it possible to reduce the number of references by pooling components, and to reduce the production time by eliminating certain assembly phases that are postponed to the end customer.
The tradesperson only needs to have three basic modules in order to install or carry out the maintenance of any configuration of the system. Therefore, this reduces their stocks and their purchasing costs.
In addition, this makes it possible to increase the upgradeability of the product. Indeed, a module may subsequently be available in a plurality of versions. For example, the electronic part may be more or less intelligent. Thus, by only changing one module, the overall product can be transformed on the basis of the needs. In this case, the tradesperson may, for example, have two or three distinct control modules to be able to implement a wide range of installation combinations.
Moreover, the use of three modules of small size and flexibly connected to one another (cables, pipes) makes many implantations and adaptations possible, in particular in highly restricted environments, compared to a single product in a rigid casing.
For the industrialist, this makes simplified stock management possible since there are only three modules (or series of modules), that are identical for all system configurations. In addition, upgrading the system becomes easier, since upgrading one of the modules does not affect the manufacture of the others.
According to a particular embodiment of the invention, at least one first of said modules has a casing configured to be assembled with a casing of a second of said modules, so as to attach said first and second module.
Thus, attaching these casings makes it possible to obtain a first assembly type and therefore a first configuration of the system. This attachment also makes it possible to improve the volume of the system, and facilitates the hydraulic and/or electrical connections.
This attachment is preferably reversible, and achievable, for both the attachment and for the separation, without tools.
According to a particular embodiment of the invention, said casings have shapes adapted to interlock, for example by having respectively a contained dovetail tenon and a containing dovetail groove. Of course, many other means and shapes can be envisaged, for a simple and effective attachment, using means for interlocking (pins, clips, etc.) or another mode of attachment (magnets, Velcro®, etc.).
Thus, the assembly is simple and quick to implement, as is the industrialisation.
According to a particular embodiment of the invention, said first and second module are said control module and said pumping module.
Thus, it is possible to group, if necessary, these two modules, the detection module being at a distance. This improves the adaptability of the system to the various installation configurations.
According to a particular embodiment of the invention, said system comprises a removable attachment part for attaching to one another said detection module and said pumping module and/or said control module.
According to a particular embodiment of the invention, said attachment part comprises a plate having on the one hand means for attaching to said detection module and on the other hand means for attaching to said pumping module or to said control module.
This approach has the advantage of being able to implement the invention easily, particularly with pre-existing casings. It is also possible that the plate, or equivalent means, are integrated directly in the casing.
According to a particular embodiment of the invention, said attachment part makes it possible to install said pumping module and/or said control module in vertical position.
This particularly makes it possible to obtain a system similar to the one-piece device of the prior art, described above, and for example an installation in an elbow. In this particular case, the plate and the casings are organised so as to be placed in the elbow, taking into account the specific constraints thereof (internal walls, guides, holding elements, etc.). Consequently, this improves the adaptability of the system to the various installation configurations.
According to a particular embodiment of the invention, said attachment part has at least one portion for guiding and/or clamping at least one of said connection means.
This makes it possible to facilitate the installation and improve the holding of the system during positioning and after installing.
According to a particular embodiment of the invention, said guiding and/or clamping portion comprises a housing for receiving a clip for holding a tube.
According to a particular embodiment of the invention, at least one of said modules has a casing wherein a housing is formed for receiving, at least partly, and/or for guiding, an electrical cable and/or a tube.
Thus, this makes it possible to save space and optimise the volume of the system, making it possible for it to adapt to all installation configurations, the cables or tubes being able to be fully or partly housed in the equivalent parallelepiped volume of the casing, and not circulate along it. In other terms, the available space simply needs to correspond to the equivalent volume of the casing, to make the installation possible.
Furthermore, this facilitates the installation, the location of the cables and tubes being defined, or at least suggested.
Thus, according to a particular embodiment of the invention, one of the modules, for example said pumping module, comprises at least one groove capable of receiving an electrical cable connecting said detection module to said control module.
Likewise, according to a particular embodiment of the invention, one of said modules, for example said control module, comprises at least one housing capable of receiving a tube connecting said detection module to said pumping module.
According to a particular embodiment of the invention, said pumping module comprises an oscillating piston pump.
Other types of pumps may of course be implemented. The pumping module may moreover also particularly comprise a thermal protection and the connection to the control module.
According to a particular embodiment of the invention, said detection module comprises at least one sensor belonging to the group comprising:
The various particular features listed above may of course be combined with one another, according to all possible configurations.
The invention also relates to each of the modules itself, and in particular:
More specifically, the invention also relates to a pumping module for a condensate removal system comprising at least three independent modules:
The invention also relates to a detection module for a condensate removal system comprising at least three independent modules:
The invention also relates to a control module for a condensate removal system comprising at least three independent modules:
The invention also relates to a method for installing and/or maintaining a condensate removal system according to one of the preceding implementations, comprising the following steps of:
Thus, the invention makes it possible to obtain various configurations of the system, making it possible for it to adapt to any type of installation environment using one or other of the configurations, based on the three modules available.
According to a particular embodiment of the invention, said method comprises a step of replacing and/or intervening on only one of said modules.
Thus, the maintenance of the system is simpler and less expensive since only a single module and not the whole system needs to be changed. It is also possible to upgrade the installation, by replacing one of the modules, for example the control module by a higher performance version, without replacing the entire system.
According to a particular embodiment of the invention, in said one-piece configuration, said modules are assembled so as to be able to be housed particularly in an elbow installed on one side of a wall-mounted air-conditioning unit.
Thus, the system is extremely compact and adapts to a particular type of installation configuration. With the same modules, it is possible to address the specific constraints of these elbows, which generally require a specific model, while addressing the constraints of other situations, for example when the available space extends over a low height (aligned configuration).
Other aims, features and advantages of the invention will become apparent upon reading the following description, given purely by way of illustrative and non-limiting example, and that refers to the appended figures, wherein:
The general principal of the invention is based on a modular approach of condensate removal systems according to which it is possible to obtain at least the pumping, control and detection functions in at least three distinct separate modules, connected to one another via hydraulic and/or electrical connections. These three modules are designed to be assembled together, thus making it possible to create at least two installation configurations used in the trade.
The condensate removal system of the invention therefore consists of at least three modules:
Each of these modules is configured, independently, to make it possible to implement these various configurations, as described hereinafter. Thus, each of these modules, considered independently, is novel and is one of the objects of the invention, in the same way as the corresponding installation and/or maintenance method.
In the embodiment described, three distinct installation configurations can be implemented according to the invention:
The assembly of the modules can be carried out by various reversible attachment means: assembly by interlocking (elastic interlocking, sliding tenon, etc.), using magnet(s), screws, pin(s), using additional attachment part(s) (for example a plate with hooking/attaching means), etc.
All of the modules are optimised to obtain a minimum size and a maximum flexibility, making it possible to adapt to the shapes and constraints of each installation environment, this using only three modules. This optimisation may particularly result in the implementation of adapted overmouldings, by integrating/embedding tubes and/or cables to the casings of the modules using recess(es), (notch(es), groove(s), etc.).
According to the implementation illustrated, the pumping module (20) consists of a pump (23), that may have an oscillating piston, of a thermal protection and of connection to other modules. In a particular implementation, the connection means can be:
In this particular embodiment, the pumping module is overmoulded with its PCB and a plug-in connector (shown in
In addition, in this particular embodiment, the overmoulding is adapted to make it possible to assemble the pumping module with a second module.
Finally, in this particular embodiment, the overmoulding is also equipped with recess(es) for embedding a cable (connection means between the modules or also, a power cable, etc.) and/or a pipe. This makes it possible to reduce to the minimum the dimensions of the system after assembly. Examples of grooves and of assembly configurations are illustrated in
The detection module (40) consists of a tank (42) and of a detector (41) capable of detecting at least two levels of condensates in the tank. In this particular embodiment, this module is connected via a hydraulic connection (64, 84, 91) to the pumping module (20) and via an electrical connection (61, 81) to the control module (50). This module makes it possible to detect the presence of water which makes it possible to activate the pump. The detection may be performed with any type of technology such as float detection, capacitive detection, resistive detection, optical detection, etc.
The control module (50) communicates with the other two modules. In this particular embodiment, this communication is carried out via electrical cables (61, 62, 81, 82). This module makes it possible to control the pump on the basis of the levels of condensates detected by the detection module.
In a particular embodiment, the control module (50) consists of a plastic shell in two parts (52, 54) wherein an electronic board (53) equipped with a connector is installed for connecting/controlling the pump (62, 82) and the detector (61, 81).
In a particular embodiment, this module may be intelligent and communicate with other modules or even with a central unit.
In a particular embodiment, the casing of this module is equipped with a shape for assembling with another module.
In this particular embodiment, the casing (52, 54) of the control module (50) has a housing (55) capable of receiving a tube (65), connecting the tank (42) of the detection module (40) to the pumping module (20).
In the so-called aligned configuration, the control module (50), the pumping module (20) and the detection module (40) are separated and substantially aligned so that the assembly can, for example, be installed directly in the lower part of a wall-mounted air-conditioning unit, the useful height of which is restricted (
In this particular embodiment, the modules are disposed such as illustrated in
In the two-piece configuration, two modules are assembled whereas the others remain separated, all of the modules are connected by connection means (61, 62, 64).
In this particular embodiment, illustrated in
In this embodiment, the various modules are connected by electrical cables (61, 62) and pipes (64) in a similar way to the preceding configuration.
The one-piece configuration makes it possible to assemble the pumping module (20), the control module (50) and the detection module (40) to form a one-piece product.
In this embodiment, this is permitted by a removable attachment part (92). The removable attachment part makes it possible to install the pumping module (20) and/or the control module (50) in vertical position. In one embodiment, the attachment part (92) has a guiding (922) and/or clamping function guaranteeing a holding of at least one connection means.
In this particular embodiment, the attachment between the block (20-50) formed by the pumping module and control module and the detection module (40) is permitted by the use of a shaped hose (84) (
In another embodiment, the attachment between the block (20-50), formed by the pumping module and the control module, and the detection module (40) is permitted by a plate (92) (
The modules are disposed such as illustrated in
Such a configuration can be used and inserted into an elbow (11) installed on the side of a wall-mounted air-conditioning unit (
The method for installing the system described above is illustrated in
In the event of failure of the system, it is necessary to carry out maintenance thereof.
In a particular embodiment, apart from an eco-design based on the use of recyclable plastics, the product may be part of an eco-responsible logic.
