Description

TITLE OF INVENTION:
A cold- or heat-generating arrangement.
TECHNICAL FIELD
The present invention relates in general to a cold- or heat-generating arrangement and more particularly to such an arrangement which displays a heat exchanger acting as a vaporiser unit, a compressor unit connected thereto adapted to raise the pressure of a gas formed in the vaporiser unit, and a heat exchanger acting as a condenser unit, as well a throttle device adapted to regulate the flow of a gas condensed in the condenser unit.
The arrangement proposed according to the present invention may be employed in a per se known manner for cooling, in which event the arrangement is entitled a "liquid cooler assembly", or alternatively be employed in a per se known manner for heating, in which event the arrangement is entitled a "heating pump".
The present invention will be described in greater detail hereinbelow in a heating pump application and the skilled reader of this specification would be well aware of the modifications required for an application as a cooler liquid assembly.
BACKGROUND ART
Methods and arrangements of the above-outlined nature are previously known in a plurality of various embodiments.
One example of the state of the art and the technical field to which the present invention relates is shown and described hereinbelow with reference to the appended Fig. 1.
Different types of liquid cooling and heating generating assemblies are thus previously known in the art where a coolant circuit, also called a compressor-driven vaporisation process, cools a medium and causes energy to be emitted to a another medium.
If the process is employed for cooling, the process is utilised in a cooler assembly, but if the process is employed for heating, the process is utilised in a heating pump.
Processes and arrangements of the type contemplated here consist of a first heat exchanger unit in the form of a vaporiser unit which is adapted to be able to take up energy, a compressor unit which is adapted to raise the pressure of the gas formed in the vaporiser unit, as well as a second heat exchanger in the form of a condenser unit which is adapted to lead off energy and thereby cause the gas to condense into a liquid, as well as a throttle device (valve) which is adapted to regulate the flow of the condensed gas from a high pressure side to a low pressure side.
It is further previously known in the art that such an arrangement is in principle constructed from three different units interconnected by free pipes, namely a vaporiser unit, a compressor unit and condenser unit and where the vaporiser unit, with the aid of associated free conduits or pipes, is connected to the compressor unit and the condenser unit is correspondingly, with free conduits or pipes, connected to the compressor unit and where this interconnection of the units has proved to require considerable space.
If measures are implemented to sound insulate or sound damp the three interconnected units, it will be obvious that a casing, which is to enclose said units requires large outer dimensions, in particular while utilising the requisite sound- insulating material.
Measures of the type contemplated here afford the disadvantage that leakage, within and between the units, will be difficult to discover.
Observing the technical considerations which are applicable in an arrangement, according to the present invention, it might also be mentioned that it is previously known in the art, for various ways of sound insulation, to separate a sound- generating unit or an arrangement from the ambient atmosphere by enclosing the arrangement in a specifically designed casing.
It is also previously known in the art that, apart from a sound reduction, heat emission depends on the magnitude of a selected partial vacuum, to the extent that a selected higher partial vacuum (lower pressure) affords a more efficient sound reduction and thermal insulation.
The contents of Patent Specification DE-Ul -79 08 625 form part of the state of the art.
This Patent Specification shows and describes a module-adapted heating pump to be able to heat up hot water and consumer water and where this modular heating pump is to consist of a number of mutually independent insertable modular units (1; 2; 3; 4) and where these are intended to be enclosed in a sound-damping casing (5).
In this instance, the modular units are structured to be stacked over one another inside a casing (5).
It is further disclosed that damper elements (16) are inserted between a support plate (17) provided for the modular unit and rails for the insertion movement.
More particularly, it is disclosed that the requisite interconnecting conduits (14, 15), between the discrete modules and an aggregate or unit shaft (10, 11), are to consist of flexible and agent-resistant hoses.
More particularly, this is a case of coordinating the modules over one another and creating a cohesion unit using connection conduits.
Patent Specification GB- A-2 071 294 shows and describes a condenser unit related to a heating pump and where the unit comprises an electric motor (3) which is driveably connected to a compressor (2), an oil separator (7), an oil receptacle (9) and a condenser (13), all being coordinated inside a hermetically sealed cylindrical casing (1).
On its outside, the casing is covered by a thermal and acoustic material (15) where the interior of the casing is directly connected by the intermediary of pipes (12) to the pressure side of the compressor (2) via the oil separator (7) and the conduit (6).
The motor-compressor unit (3, 2) displays a lubrication system (10, 11) which cooperates with the oil receptacle (9) and where the stator of the electric motor (3) is surrounded by the windings of a wound tube (13) where said tube forms the utilised condenser.
CONSIDERING THE PRESENT INVENTION TECHNICAL PROBLEM
Considering the circumstance that the technical deliberations that must be made by a person skilled in the art to be able to offer a solution to one or more technical problems posed is, on the one hand, initially a necessary insight into the measures and/or sequence of measures to be adopted and, on the other hand, a necessary selection of the means required, the following technical problems are likely, in view hereof, to be relevant in the evolution of the subject matter of the present invention.
Considering the state of the art, as described above, it should therefore be seen as a technical problem to be able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order, in a efficient manner, to induce a reduction in the sound of vibrations related to the compressor unit from a cold- and/or heat-generating arrangement.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause a vaporiser unit, a compressor unit, a condenser unit and said throttle device to be closely coordinated and enclosed within a hermetically sealed casing, principally structured as a sound-reducing barrier.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to cause the interior of said casing to be subjected to an adapted, selected partial vacuum, which deviates negatively from any atmospheric pressure.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required on ascertaining that the internal pressure within the casing deviates from an initially selected pressure, such as a predetermined level, and to be able to interpret a pressure change against atmospheric pressure as a leakage within the arrangement.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which derive from causing a thus selected partial vacuum within the casing to create a sound-damping effect.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will derive from causing a vaporiser unit and a condenser unit to be directly coordinated adjacent one another and mounted to the inside of said casing.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which derive from causing the vaporiser unit and the condenser unit to be fixedly related to a wall section of the casing. There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which derive from causing conduits (hoses or piping) between a sound-generating compressor unit and said vaporiser unit or alternatively condenser unit to be formed so that they display and offer a low sound conducting capability.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will derive from causing said compressor unit to be adapted to support against the bottom section of the casing by the intermediary of sound-damping and elastic cushions.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will derive from causing, at a selected excess pressure within the casing, the creation of preconditions for reducing selected normal dimensions for the utilised conduits and piping.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will derive from causing said casing to be dimensioned in accordance with those directives which apply to the construction of a pressure vessel.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which derive from causing said casing to be filled with a gas related to a cooler circuit.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will derive from rapidly being able to interpret a minor pressure change within the casing as a leakage inside the enclosed arrangement. There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which derive from utilising, in a partial vacuum inside the casing, that circumstance that enclosed units and components within the casing will be insulated from one another and/or from the ambient atmosphere in terms of temperature.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will derive from the circumstance that, at a selected excess pressure within the casing, the units and the piping may be built with components which are dimensioned to be able to accommodate prevailing pressure differences between the casing and components, which offers the utilisation of higher pressure with standard components.
There resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will derive from causing the casing to be filled with a chemical medium in order, in such instance, to create the preconditions for rendering a coolant medium innocuous before it reaches the atmosphere.
Considering the state of the art, as described above, it should therefore be seen as a technical problem to be able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order, in an arrangement of the type disclosed by way of introduction, regardless of whether the arrangement is utilised as a cooling assembly or as a heating pump, to coordinate and/or structure the included parts and units so that these may be coordinated to a more compact integrated unit with or without the use of a sound- reducing barrier or the like.
There then resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which derive from causing a vaporiser unit, a compressor unit and a condenser unit to be coordinated with one another so that they form an elongate, integrated unit and that thereby the requisite conduits (intended for gas or liquid) will be able to be coordinated within integrated unit.
There then resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required by causing the vaporiser unit to be coordinated with one side of the compressor unit while the condenser unit can be coordinated with the other side of the compressor unit.
There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will derive from causing said compressor unit to consist of a compressor and that an oil separator related to the compressor can be interconnected between the compressor unit and the condenser unit.
There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to create a wholly integrated liquid cooling assembly.
There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order that an assembly be capable of being built-up from the main components of vaporiser unit, compressor unit and condenser unit and to integrate the components into an elongate unit.
There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order that the requisite outer conduits or piping between the components and the units on the gas side, within the cooler circuit, will be eliminated in order by such means to obviate leakage risks already in the basic construction. There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to permit the requisite quantity of coolant medium in the cooler circuit to be reduced.
There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order to be able to offer an integrated construction where otherwise occurring pressure drop and losses related thereto may be reduced.
There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will be required in order that, because the cooler circuit is wholly integrated, the risk of the occurrence of pollutants and contaminants within the cooler circuit is reduced.
There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will derive from the oil separator being able to be included as a part of the pressure vessel of the condenser unit.
There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which will derive from the oil cooler being designed as a siphon cooler, arranged in the bottom of an oil separator.
There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which derive from the coolant medium liquid from the condenser unit being allowed to circulate naturally between the bottom of the oil separator and the condenser unit, the coolant medium boiling and absorbing energy from the oil. There also resides a technical problem in being able to realise the importance of, the advantages associated with and/or the technical measures and considerations which derive from causing the motor section of the compressor unit to function as a liquid separator, arranged between the vaporiser unit, and the compressor unit where a utilised electric motor will assist in vaporising that part of the coolant medium which has been separated.
SOLUTION The present invention thus takes as its point of departure the state of the art as disclosed by way of introduction where a cold- or heat generating arrangement requires a heat exchanger unit active as a vaporiser unit, a compressor unit connected thereto and adapted to raise the pressure of a gas formed in the vaporiser unit, and a heat exchanger unit acting as condenser unit as well as a throttle device formed as a valve and adapted to regulate the flow of a condensed gas and where said connected compressor unit generates vibrations.
In order to be able to solve one or more of the technical problems outlined above, the present invention particularly discloses that the prior art be supplemented with the feature that said vaporiser unit, said compressor unit, said condenser unit and said throttle device be closely coordinated and enclosed within a hermetically sealed casing, that the interior of said casing is placed under a selected pressure which deviates from atmospheric pressure, and that an inner pressure within the casing deviating from the selected pressure by a predetermined value is to be interpreted as a leakage.
As preferred embodiments, falling within the scope of the fundamental concept of the present invention, it is disclosed that a sound-damping effect moreover be created at a selected partial vacuum within the casing. It is further disclosed that a vaporiser unit and a condenser unit be directly mounted to the inside of said casing and where these units are fixedly associated with wall sections of the casing.
Further, the present invention discloses that utilised piping and conduits, between the compressor unit as sound generating unit and said vaporiser unit or alternatively condenser unit, are formed so as to afford a low sound conducting capability.
Within the scope of the present invention, there also falls the possibility of causing said compressor unit to be adapted to support against the bottom section of the casing by the intermediary of sound-damping and elastic cushions.
At a selected excess pressure within the casing, preconditions are created for reducing selected dimensions for utilised piping or alternatively for causing the pressure of utilised standard components to be increased.

The advantages which may principally be considered as significant of the present invention and the significative characterising features thereby disclosed are that preconditions of hereby being created for incorporating, within a hermetically sealed casing, a cold- or heat-generating arrangement of the nature disclosed by way of introduction.
By creating a partial vacuum within the casing, a possibility is afforded of effectively damping vibrations from, principally, the compressor unit and thereby creating a sound damping of the sound waves which pass through the casing to the ambient atmosphere at the same time as a possibility is afforded of being able in a simple manner by pressure measurement to evaluate whether the cold- or heat-generating arrangement displays a leakage or not.
By creating an excess pressure within the casing, a possibility will be afforded of readily reducing the dimensions of utilised piping and enclosed units of alternatively by causing the working pressure of the units to be increased.
It is further disclosed, as an alternative, that there have hereby been created preconditions for offering an extensive compacting of a cold- or heat-generating arrangement in such a manner that a vaporiser unit, a compressor unit and a condenser unit will be able to be coordinated with one another for the formation of an elongate integrated unit.
As a result of the integrated unit disclosed here, it will be possible to cause the requisite conduits (gas conduits, liquid conduits) to be coordinated within the unit.
That which may principally be considered as characteristic of the present invention is disclosed in the characterising clauses of appended Claims land 10. BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS

DESCRIPTION OF A PRIOR ART UNIT IN ACCORDANCE WITH FIG. 1
With reference to Fig. 1, there is shown in perspective a cold- or heat- generating arrangement 1 with a heat exchanger acting as a vaporiser unit 2, a compressor unit 3 associated thereto, rotatably driven by a motor 4 and adapted to raise the pressure of a gas formed in the vaporiser unit 2, and a heat exchanger active as condenser unit 5, as well as a throttle device 6 active as a valve, adapted to regulate the flow of a thus condensed gas.
It will further be apparent from Fig. 1 that the heat exchanger unit 2 and the heat exchanger unit 5 consist of two separate units, laterally oriented to the compressor unit 3 with an associated electrically driven motor 4 and where a number of conduits 7, 7a are coordinated between the compressor unit and the heat exchanger unit 2 and also between the compressor unit 3 and the heat exchanger unit 5, where these conduits (piping) have been given reference numerals 8, 8a.
In addition, a conduit (7a, 8a) is utilised which cooperates with the throttle device 6 requisite for the arrangement.
DESCRIPTION OF CURRENTLY PROPOSED EMBODIMENT
It should be emphasized by way of introduction that, in the following description of currently proposed embodiments which display the significative characterising features related to the present invention and which is clarified by means of the figures shown in the accompanying Drawings, we have selected terms and a special terminology with the intention principally of clarifying the inventive concept.
However, in this context it should be observed that the expressions selected here should not be considered as restrictive exclusively to the terms selected and utilised here but it should be understood that each thus selected term is to be interpreted so that, in addition, it encompasses all technical equivalents which function in the same or substantially the same manner in order thereby to be able to attain the same or substantially the same intention and/or technical effect.
With reference to Fig. 2, the basic preconditions of the present invention are thus schematically illustrated as applied to a heating pump arrangement 1 according to Fig. 1 and where the significative properties related to the present invention are shown in more concrete detail as a result of the currently proposed embodiments which will now be described in greater detail hereinbelow.
Thus, Fig. 2 is a perspective presentation showing, by means of broken lines, a casing 10 surrounding the cold- or heat generating arrangement 1 illustrated in Fig. 1. An alternative to the arrangement 1 according to Fig. 1 is shown and described with reference to the perspective illustration according to Fig. 3.
Fig. 2 shows that a pressure absorbing (partial vacuum, excess pressure) casing 10 is to surround the arrangement 1 and that, as a first alternative, a partial vacuum in relation to atmospheric pressure is to prevail within the casing 10 in order thereby simply to be able to establish, by means of a pressure change, whether the arrangement 1 displays leakage or not.
With reference to Fig. 2, an application is illustrated there of the present invention where a casing 10 may enclose an arrangement 1 shown and described in greater detail in Fig. 1 and where the units, associated to the arrangement 1, have been given the same reference numerals as in Fig. 1.
Fig. 2 also illustrates that the utilised compressor unit 3 with motor 4 generates vibrations which are to be reduced by the casing 10 in order that sound perceptions will occur outside the casing which are intended to be reduced in relation to the vibrations of the compressor unit 5 inside the casing 10.
With reference to Fig. 2, this figure shows that the vaporiser unit 2, the compressor unit 3, the condenser unit 5 and said throttle device 6 are to be coordinated and enclosed within a hermetically sealed casing 10.
Said casing 10 is to be placed under a selected pressure which is to deviate from atmospheric pressure and, at an inner pressure which may be determined by means of a pressure gauge 9 within the casing deviating from the selected pressure by- a predetermined value is to be interpreted as a leakage within the arrangement 1.
More particularly, the present invention discloses that, at a selected partial vacuum within the casing 10, this is to be selected so that there is thereby created a sound- damping effect at a predetermined level. A vaporiser unit 2 and a condenser unit 5 may now advantageously be directly mounted to the inside of said casing 10 and where the units 2, 5 are then to be fixedly secured in relation to wall sections 10a, 10b, respectively, of the casing 10 or alternatively to the wall section 10c.
Conduits 7, 7a; 8, 8a, between the compressor unit 3 as sound-generating unit and said vaporiser unit 2 or alternatively condenser unit 5, are to be formed so as to afford reduced sound-conducting capacity.
Said compressor unit 3 may be particularly adapted to support against the bottom section 1Od of the casing 10 by the intermediary of sound-damping and elastic cushions 11.
At a selected excess pressure within the casing 10, preconditions are created to be able to reduce the selected dimensions for utilised piping 7, 7a; 8, 8a but also for the units 2, 3 and 5.
More particularly, said casing 10 is to be dimensioned as a pressure vessel and principally adapted to be able to withstand a selected partial vacuum.
Said casing 10 is advantageously to be filled with a gas related to a coolant circuit.
With reference to Fig. 3, this figure shows a perspective view partly in section of an alternative to the embodiment illustrated in Fig. 2, where the casing 10' has been given the form of a pressure vessel.
This pressure vessel 10' encloses the vaporiser unit 2 and the condenser unit 5 and these may be coordinated closely to one another, since a partial vacuum inside the casing 10' reduces thermal propagation.
An inlet pipe for a coolant has been given reference numeral 13 and an outlet pipe reference numeral 13 a. An inlet pipe for the heat carrier has been given reference numeral 14 and an outlet pipe reference numeral 14a.
Otherwise, the preconditions described above in conjunction with the embodiment according to Fig. 2 also apply to the embodiment according to Fig. 3.
Thus, Fig. 4 shows a cold- or heat-generating arrangement 10 with a vaporiser unit 12, an electrically driven motor 14, a compressor unit 13, an oil separator 17 and a condenser unit 15, and may be used with or without the use of a sound-reducing barrier or the like.
Fig. 4 illustrates the utilisation of an internally oriented throttle valve 16.
It is of importance for the present invention that the vaporiser unit 12, the compressor unit 13, 14 and the condenser unit 15 be coordinated with one another for the formation of an elongate integrated unit.
Further, it is shown in Fig. 2 that the requisite gas conduits will be able to be coordinated within the unit.
Further, Fig. 2 intimates an obscured conduit acting between the vaporiser unit and the condenser unit with an associated, integrated throttle valve 16 which is shown laterally oriented to the integrated elongate unit for the compressor unit 13, its associated motor unit 14 and an oil separator unit.
The embodiment according to Fig. 4 illustrates an inlet connection 15a for the condenser unit 15 and an outlet connection 15b for said connections 15a and 15b intended for coolant water. The embodiment according to Fig. 4 further illustrates an inlet connection 12a for the vaporiser unit 12 and an outlet connection 12b with said connections 12a and 12b intended for the coolant carrier.
The embodiment according to Fig. 4 may advantageously be surrounded by a casing 10 and thereby can the preconditions disclosed in Figs. 1 to 3 be satisfied.
The present invention is naturally not restricted to the embodiment disclosed above by way of example but may undergo modifications without departing from the scope of the inventive concept as illustrated in the appended Claims.
hi particular, it should be observed that each illustrated unit and/or circuit may be combined with each other shown unit and/or circuit without departing from the scope of the invention in order to be able to attain the desired technical function.
