Description
Transcritical Refrigeration Display Unit
The subject of the present invention is a display unit comprising at least one compressor, at least one fluid/gas heat exchanger for cooling the compressed gas, at least one evaporator, at least one expansion device and conduits connecting the afore- mentioned components with each other to form a
"transcritical" refrigeration circuit, especially a carbon dioxide refrigeration circuit. The term "transcritical" refrigeration circuit refers to a refrigeration circuit which can be operated in a subcritical as well as a super- or transcritical mode.
The term "display unit" shall include all kind of display units, especially cabinets, multideck cabinets, roll-in cabinets, counters et cetera. Display units as mentioned before are well known to a skilled person.
EP-A-O 908 688 discloses display units as described above as well as a refrigeration plant, by which one or more display units are connected via their fluid/gas heat exchangers to a refrigeration cycle. The heat given up from the transcritical refrigeration circuit of each display unit via its fluid/gas heat exchanger is discharged to the refrigeration cycle. Within the refrigeration cycle a fluid such as water is circulating; an anti-freeze-agent may be added to the circulating fluid if required. These kinds of refrigeration cycles are designed in a way that their pressures do not exceed 25 bar.
Within transcritical refrigeration circuits of display units pressures of 90 bar and more occur. For that reason all components and conduits mentioned above have to be able to withstand these high pressures. Nevertheless, neither the owner and service persons of supermarkets nor their customers are interested
in being confronted with such high pressures. Additionally each leak in a component or conduit can result in bigger problems as any gas escaping from a leaking high pressure conduit or component can result in serious injuries of service persons and customers.
The main object of the present invention is to provide a display unit, which avoids the above-discussed problem regarding the high pressures within a transcritical refrigeration circuit, especially within a carbon dioxide refrigeration circuit.
A further object of the present invention is to provide a display unit, which in case of any fault of one of the above-mentioned components enables an easy and quick replacement of a non-operating component by an operating component. This replacement of a non-operating component should be manageable even by a person not skilled in the art.
Furthermore, it is an object of the present invention to provide an assembly of the above-mentioned components and conduits, which can be (pre)manufac- tured and which only has to be integrated into the display unit at the display unit's production site or in the supermarket.
In accordance with an embodiment of the present invention, this problem and these objects are achieved by a display unit as claimed in claim 1.
The innovative concept upon which the present invention is based is that at least the compressor and the fluid/gas heat exchanger are arranged within a compartment, which can be removable from the display unit.
The compartment should be designed so as to be stable enough to at least substantially reduce the effect of any breach or leakage of any of the compo—
nents comprising the refrigerant under pressure. Various materials can be used for the compartment, for example metal sheet, plastic material, etc. It is also possible to use different material in combination, for example a hard shell together with a dampening material. It is particularly possible to provide the hard shell at the outside and the dampening material at the inner side thereof. It is also possible to provide the compartment with a venting means, like an opening, a discharge valve, etc. in order to allow venting of the refrigerant after a failure of the refrigeration circuit.
It is possible to removably attach the compartment to a support structure within the display unit, for example a frame, etc. of the display unit. The compartment can comprise an attachment means, like an attachment flange, for attaching the compartment to the support structure. It might be sufficient to have the compartment rest on the support structure, it is also possible to additionally secure the compartment removably thereto, for example by means of a nut and bold fastener. A positioning means can be provided with the support structure and/or with the compartment in order to ensure a precise positioning of the compartment in the installed condition. The positioning means can have a conical shape or can be V— shaped in order to allow for easy inserting as well as precise positioning.
Display means, like instruments, a screen, etc., for displaying an operational condition and/or operating means, like knobs, etc. can be provided on the compartment's outer side in order to adjust cooling output, correct temperature, etc. A powerline with a plug may lead out of the compartment. Similarly, signal lines can be provided. Quick couplings can be provided in order to fluidly couple components within the compartment with exterior components, conduits, etc. Accordingly, the compartment can easily be replaced by merely decoupling the quick couplings and unplugging the powerline.
90 For cooling the fluid/heat exchanger, it is possible to provide a "back cooling" to the compartment or directly to the fluid/gas heat exchanger. Such back cooling can be provided by means of a "low pressure" cooling circuit, e.g. with another refrigerant and even with air or water. The respective conduits can be connected to the compartment with a quick release coupling, for example.
95
In accordance with an embodiment additional or all of the above-mentioned components forming the transcritical refrigeration circuit are arranged within said compartment.
loo In case of any leak in one of the above-mentioned components or conduits the compartment will function as a buffer for the escaping gas. For that reason no direct disturbance or harm to service persons and customers should occur.
In case of any fault of one of the above-mentioned components the
105 component does not have to be repaired within the display unit or replaced from the display unit, which normally takes for at least 30 minutes. During this period the display unit is out of order. According to the innovative concept the whole compartment can be removed and replaced by another compartment, housing operating components. The time for replacing the compartment takes no about 10 minutes or less. The repair of the non-operating component can then be realized without any time pressure and stress.
According to a further embodiment of the present invention the compartment is preferably arranged below the show room or storing compartment of the 115 display unit.
This arrangement enables an easy and quick replacement of the compartment.
Further characteristics and advantages of the invention will become clearer 120 from the following detailed description of preferred embodiments thereof, described by way of nonlimiting examples with reference to the attached drawings, in which:
Figures 1 and 3 are schematic lateral cross-sections of preferred embodiments 125 Figure 2 is a schematic perspective view of the same preferred embodiment as shown in figure 1
In figures 1 and 2 a multideck cabinet C is shown. Below the show room or storing compartment S a compartment 1 is arranged. Within that compartment
130 1 a compressor 2, a fluid/gas heat exchanger 3 for cooling the compressed gas and conduits - not shown in figures 1 to 3 - are arranged. Outside of the compartment 1 an evaporator 4 and an expansion device - not shown in figures 1 to 3 - are arranged; the afore-mentioned components are connected with each other to form a transcritical refrigeration circuit, especially a carbon
135 dioxide refrigeration circuit, as e. g. described in the above— mentioned EP- A— 0908 688.
The aforementioned expansion device is preferably designed as an expansion valve, while the compressor 2 is preferably designed as a frequency controlled no compressor.
According to a further embodiment of the present invention the amount of the medium, circulating in the transcritical refrigeration circuit does not exceed 1000 g.
145
As can be seen from figure 3 (cooling) air 6 is forced by the ventilating fans 5,5' to flow through the evaporator 4, wherein the air is cooled against the evaporating refrigerant of the transcritical refrigeration circuit, and via the back-
flow-channel 7 to the show room or storing compartment S of the multideck 150 cabinet C. This flow of the circulating cooling air is already known to a skilled person.
The ventilating fans 5,5' are especially frequency controlled ventilating fans. This enables an optimal adaptation of the power of the ventilating fans 5,5' to 155 the required cooling capacity.
According to the embodiment shown in figure 3 all aforementioned components forming the transcortical refrigeration circuit are arranged within a compartment 1, that can be removed as a whole from the multideck cabinet C.
160
Not shown in figures 1 to 3 is the at least one quick coupling, by which the fluid/gas heat exchanger 3 can be connected easily and quickly to a refrigeration cycle or plant.
165 If the compartment 1 has to be removed or replaced by an other compartment only the connection to the power source, which is at least necessary for the compressor(s) and the fan(s), and the quick coupling have to be separated.
More and more, display units as described above are built as modules having 170 the same dimensions, e. g. a length of 1250 mm. These modules are connected to each other in case a display unit having a length of x * 1250 mm (wherein x = 1, 2, 3, ...) is required.
According to a further embodiment of the present invention each module has 175 its own compartment 1.
