Description

HEATING SYSTEM WITH HEAT PUMP FOR INTERNAL INSTALLATION
Description
The invention relates to a heating system with heat pump for internal installation. The term "heating" in the present context is intended to be understood to include both the functions typical of a heat pump, that is both the functions of summer cooling and of winter heating.
In the specific technical field, there are known heat pump heating systems which are intended to be fitted to installations for heating or cooling buildings and/or for producing hot sanitary water and which make use of a refrigerating fluid/external air exchanger as a source of heat energy and a refrigerating fluid/water exchanger for thermally processing the internal environments with respect to the building and heating the sanitary water.
Similar systems are known, for example, from
Typically, in these systems, there is provided a monobloc cabinet which contains all the components of the installation and which is in turn connected to an external unit of the split type, or containing an air/refrigerating gas exchanger and a relevant compressor. The components are in turn connected to potential expansion tanks and storage tanks for the treated water which are normally positioned in another environment.
A first disadvantage of the known systems involves the general dimensions thereof, which makes the transport and installation thereof rather difficult. Another disadvantage involves the fact that the apparatus as marketed is incomplete and requires other elements outside the actual cabinet (external unit) for complementing an installation of the functional assembly.
An object of the invention is to provide a heating system with a heat pump for internal installation which is structurally and functionally configured to overcome at least one of the disadvantages set out with reference to the cited prior art.
Another object of the invention is to provide a particularly compact heating system.
Yet another object is to provide a heating system which can be supplemented in a modular manner and which, in the complete set-up thereof, contains everything necessary for the operational functioning of the installation.
These objects and other objects which will be better appreciated below are achieved by the invention by means of a heating system with a heat pump for internal installation which is constructed according to the features mentioned in one or more of the appended claims.
In an embodiment thereof, the invention provides a heating system with a heat pump for internal installation comprising a first cabinet which contains a heat pump module with a refrigerating circuit comprising an air-refrigerating fluid heat exchanger including at least two batteries which are arranged in a V-like manner and which diverge upwardly and which delimit in the cabinet at least one external compartment with respect to the V and at least one internal compartment between the tines of the V and which communicate with the external compartment exclusively through the batteries. This configuration allows an appreciable improvement in the compactness of the heat pump, in particular in the vertical development and a maximization of the surface development of the batteries. Preferably, at least one voluteless radial fan is received in a compartment above the batteries with intake in the internal compartment and discharge in the compartment above. This configuration allows advantageous use of the fan which allows discharge in all directions to be provided. The discharge intake can therefore be open at the first cabinet with freely selected positioning. In particular, it is advantageous that this discharge opening is preconfigured by providing the compartment above for an aeraulic discharge connection on three sides of the cabinet. Preferably, the three sides are the rear side and the two lateral sides, respectively.
In an alternative solution, in place of the pair of batteries arranged in a V-like manner, the system comprises at least one curvilinear battery which defines a convex side and a concave side and which delimit in the cabinet at least one external compartment and at least one internal compartment, respectively. Preferably, the internal compartment is at least partially surrounded by the concave side of the battery and communicates with the external compartment exclusively through the battery. In this case, according to a preferred configuration, at least one voluteless radial fan is also received in a compartment above the battery with intake in the internal compartment and discharge in the compartment above, wherein the compartment above is provided for an aeraulic discharge connection on three sides of the cabinet.
In a preferred solution, the external compartment is also provided for an aeraulic intake connection on three sides of the cabinet and, preferably, the three sides of the arrangement of the compartment above and the external compartment coincide. In this manner, the installation of the system is also promoted in environments with small dimensions, laterally positioning it against a side wall or positioning it in abutment with the rear wall.
The installation of the heat pump module is advantageously able to be completed with a second cabinet which contains a hot sanitary water module, the cabinets of the modules being structurally independent and provided with mutual interconnection means in order to connect them to each other in an arrangement which is alternately side by side or one above the other.
In one option of the invention, the positioning beside each other is alternately bilateral.
It is advantageous and preferable for both the modules to have front surfaces with substantially identical dimensions and preferably for the formation and configuration of the front surface to be substantially identical.
The features and advantages of the invention will be better appreciated from the following detailed description of a preferred embodiment thereof which is illustrated by way of non-limiting example with reference to the appended drawings, in which:
- Figure 1 is a longitudinally sectioned view of the heat pump unit of the heat pump according to the invention;
- Figure 2 is a perspective view of the heat pump unit of Figure 1 setting out the aeraulic connections thereof;
- Figures 3 to 5 are schematic, perspective views of the heat pump unit of the preceding Figures in an isolated installation or in an installation supplemented by a hot sanitary water unit in a position above or alongside, respectively; - Figure 6 is a schematic, perspective view illustrating the heat pump unit of the preceding Figures and the relevant possibilities for aeraulic connection;
- Figures 7 and 8 are sectioned views of the version of the invention of Figure 4;
- Figure 9 shows a detail to an enlarged scale of Figure 7;
- Figure 10 is a perspective view of the heat pump unit with the front and side panelling being removed;
- Figure 11 is a schematic, perspective view of a construction variant of the invention;
- Figures 12 and 13 are a perspective front view and a plan view from above of a detail of the variant of Figure 11, respectively.
In the Figures, there is designated 1 a heat pump unit which is used alone or in combination with a hot sanitary water unit 2 for forming a heat pump heating system 3 according to the present invention.
The heating system is intended to comprise both the configurations, that is, only the heat pump unit or the same heat pump unit integrated with a hot sanitary water unit, the latter being intended to be an additional component of the heating system.
The heat pump unit 1 comprises a first cabinet 10 which contains a refrigerating circuit of the type with a compressor 4 with an airrefrigerating fluid heat exchanger 5 including at least two batteries 6, 7 which are arranged in a V-like manner with tines which diverge upwardly from a lower vertex, near which a container 11 for collecting condensate is installed.
The batteries 6, 7 are such as to delimit in the first cabinet 10 at least a first compartment 12 which is external with respect to the tines of the V and at least a second internal compartment 13 which is between the above-mentioned tines. The two compartments 12, 13 are arranged in the first cabinet 10 so as to be able to communicate with each other exclusively by means of a flow which passes through the batteries 6, 7.
This configuration of the batteries allows an appreciable improvement in the compactness of the heat pump 1, particularly in the vertical development, and a maximization of the surface development of the batteries 6, 7.
At least one radial fan 14 which is preferably of the voluteless type is received in a third compartment 15 above the batteries 6, 7. The fan 14 is mounted with intake in the internal compartment 13 with respect to the tines of the V and with discharge in the third compartment 15 above the batteries in such a manner that the flow generated through the batteries 6, 7 is introduced into the second compartment 13, is drawn in by the fan 14 and introduced into the third compartment 15.
This configuration allows a potential omni-directionality of the discharge of the fan 14 with an advantageous use of the same fan which allows a discharge direction at the outlet from the third compartment 15, the opening of which in the first cabinet 10 can be positioned freely.
Figure 6 shows three possible arrangements of aeraulic pipes 16 following three different openings of a discharge intake 17 which is provided at the first cabinet 10 by providing in the compartment 15 above three intakes 17 which can alternately be used on three sides of the cabinet 18a, b,c. Preferably, the three sides are the rear side and the two lateral sides, respectively. The intake at the rear side is preferably open while the lateral sides are temporarily closed by removable plugs 20. In a similar manner, the first external compartment 12 is also provided for an intake connection on three sides of the cabinet by means of respective intake sockets 21 which are suitable for alternate connection of aeraulic intake pipes which are not illustrated. Preferably, the three sides of the arrangement of the compartment positioned above and the external compartment coincide and the remaining two sides are temporarily closed by removable plugs 22.
The installation of the heat pump can advantageously be supplemented by the hot sanitary water module 2 which comprises a second cabinet 23 which is provided to contain a storage tank 24, inside which there is provided at least one water/water exchanger, the configuration of which is not the subject of the present invention. In the hot sanitary water module there are also present two expansion vessels which are dedicated to the sanitary water circuit and relevant safety valve in addition to two expansion vessels which are dedicated to the heating circuit. The connection connectors of both these circuits are designated 35a, b and 36a, b, respectively, and are preferably positioned at the top of the third compartment 15 of the heat pump. In a preferred configuration of the invention, with a hot sanitary water unit alongside or with only the heat pump unit, they can be freely configured via a three-way valve 37 which is controlled by an electronic panel 38 in order to cross the two flows, of the hot sanitary water and the heating water, in order to direct them to the left-hand side and right-hand side of the third compartment 15, respectively, or vice versa, in accordance with the most advantageous position for any hydraulic attachments which are provided at the installation location. Respective discharge pipes 38 and 39 of the hot sanitary water circuit and the heating water circuit, respectively, are confluent at the inlet into the valve 37 and at the outlet from the valve 37 towards the respective connectors 35a and 36a. The control of the valve 37 determines the switching of the flows thereof. The pipes leading to the return connectors 35b, 36b are connected in common.
The first and second cabinets 10, 23 of the two modules 1 and 2 are structurally independent and are preferably both constructed with a frame 25 (for example, made from metal profile-members) which is provided with mutual interconnection means 27, 28 in order to connect the two modules to each other in an arrangement which is alternately side by side or one above the other (Figures 4 and 5). Such an arrangement can be carried out with different connections, an example of which is illustrated in Figure 9. In this example, the interconnection means 27, 28 comprise a bracket 29 which supports on the frame 25 a support 30 which is preferably of the anti-vibration type. The support 30 has an extension piece 31 which projects from the bracket 29 in order to engage (for example, in a position above) with a hole or recess 32 which is formed in the frame 25 of the other module. In this manner, there is obtained the correct centring of the two modules, for example, in a position one above the other, the retention in the mutual positioning and the mutual separation in terms of the transmission of any vibrations. In a position beside each other, the two modules can be interconnected with other means, for example, screw and bolt type connections or the like, In one option of the invention, the positioning beside each other is alternately bilateral.
It is advantageous and preferable for both the modules to have a front surface 33 with dimensions, formations and general configuration which are similar and preferably substantially identical.
In a construction variant of the invention, which is schematically depicted and without any frames in Figures 11 to 13, in place of the pair of batteries 6, 7 arranged in a V-shaped manner, the system comprises at least one battery 50 which is folded in a C-shaped manner and which defines a convex side 51 and a concave side 52 which delimit in the cabinet at least one external compartment 53 and at least one internal compartment 54, respectively. Similar details to those of the preceding example are indicated with the same reference numerals. Preferably, the internal compartment is at least partially surrounded by the concave side of the battery and communicates with the external compartment exclusively through the battery. In this case, according to a preferred configuration, at least one voluteless radial fan 14 is received in a third compartment 15 which is positioned above the battery 50 with intake into the internal compartment 54 and discharge into the third compartment 15 positioned above. In this case, the compartment 15 above is also provided for an aeraulic discharge connection on three sides of the cabinet. This arrangement allows further optimization of the internal spaces of the system and particularly allows positioning of a compressor 55 alternately in the internal compartment 54 or in the external compartment 53, making best use thereof in order to receive the set of components which are necessary for the operation of the heat pump.
The invention thereby achieves the objects proposed and affords a number of advantages, including:
- compact dimensions with respect to the market;
- insertion into the unit for hot sanitary water of all the components of the installation necessary for the complete operation thereof;
- versatility in terms of positioning of the aeraulic connections at three sides, the rear, right or left lateral sides; this allows the capacity to position the heat pump alternately against a rear wall or side wall, thereby facilitating the insertion in small spaces;
- with respect to the conventional solutions with external units of the split type, the installer does not have to carry out any refrigerating or hydronic connection between different modules of the heat pump. Furthermore, the total dimensions of the system are greatly reduced with respect to a conventional solution; there are not provided any external units and the two modules have total dimensions which are similar to those of only the internal module of the split heat pumps.
Finally, transport is made easier by the presence of two separate and complete units in each portion thereof.
