Definitions
- the invention relates to vapor compression systems and, more particularly, to a heat exchanger configuration for such a system.
- An exemplary heat exchanger system according to the preamble of claim 1 is disclosed in JP 6-207773 .
- the heat exchanger placement is very much constrained by space.
- the efficiency of the system is often low in comparison to a system with a properly sized heat exchanger due to the large temperature difference between the air and the refrigerant in the heat exchangers.
- the present invention provides a refrigeration system comprising: a compressor for driving a refrigerant along a flow path in at least a first mode of system operation; a first heat exchanger along the flow path downstream of the compressor in the first mode; a second heat exchanger along the flow path upstream of the compressor in the first mode; and an expansion device in the flow path downstream of the first heat exchanger and upstream of the second heat exchanger in the first mode, wherein the first heat exchanger comprises at least a first heat exchanger component and a second heat exchanger component arranged along a flow path of heat exchange fluid for the first heat exchanger, the first heat exchanger component being downstream of the second heat exchanger in the first mode; and wherein a fan is arranged to provide a flow of heat exchange medium past the first heat exchanger, such that the first heat exchanger component is upstream of the second heat exchanger component in the flow of heat exchange medium; characterised by a refrigerator housing defining a cassette receiving area, wherein the heat exchanger components are mounted within a cassette adapted to be inserted into
- the invention relates to a vapor compression system of a refrigerator unit and, more particularly, to the arrangement of a heat exchanger in a vapor compression system, preferably in a transcritical vapor compression system.
- greater contact area between the heat exchanger and heat exchange medium is obtained by utilizing all potentially available spaces within a particular vapor compression system to house additional components of a heat exchanger, such that the heat exchanger is implemented in a series or plurality of heat exchange components. In this manner, small available spaces are nevertheless utilized to increase heat exchange efficiency and, therefore, efficiency of the overall system.
- FIG. 1 shows a system in accordance with the present invention.
- system 10 which, in this particular embodiment, is the vapor compression system for a bottle cooler refrigeration assembly.
- FIG. 1 shows the lower portion of such an assembly, including a housing 12 containing a vapor compression system.
- FIGS.1 - 3 for further discussion of the vapor compression system, which includes a compressor 14, a downstream heat exchanger 16, an expansion device 18 and an evaporator 20.
- Compressor 14 is operative to drive a refrigerant along refrigerant lines ( FIG.3 ) first to heat exchanger 16, then to expansion device 18, and then to evaporator 20. Refrigerant flows from evaporator 20 back to compressor 14 to complete the circuit.
- first heat exchanger 16 is provided having a first heat exchange component 22 and a second heat exchange component 24. These components are positioned within housing 12 to take advantage of the spaces available such that high amounts of heat exchange can be accomplished with relatively small available spaces.
- housing 12 defines a flow path for heat exchange medium, for example air, to enter into heat exchange relationship with first heat exchanger 16.
- An upper portion of housing 12 also defines a flow path for air from within the refrigerated space (not shown, but located above housing 12 and supplied with air cooled by arrows 27) to be treated with second heat exchanger 20.
- first and second components 22, 24 of first heat exchanger 16 can and most likely will be different in size and/or shape so that these components can advantageously take advantage of the available space within a particular device.
- first component 22 has a relatively larger area in a transverse plane with respect to the flow, and is relatively thin from front to back. This is because first component 22 in this embodiment is sized to fit within a relatively narrow (from front to back) space toward the open front of housing 12.
- a second space within housing 12 in this embodiment is available beneath a wall 28 which separates one portion of housing 12 for treating the first flow of air 26 from a second portion of housing 12 for treating the second portion of air 27.
- This wall 28 extends downwardly relative to the outer contour of housing 12, and results in a restriction in flow area as air flows from the inlet end 30 to the outlet end 32 of housing 12.
- This zone of decreased cross sectional flow area results in an increase in velocity of the air flowing through this zone.
- An increased velocity flow has been found to provide improved efficiency heat exchange in heat exchangers such as that of the present invention.
- this zone has a substantially short height and yet extends much further from the inlet side toward the outlet side as compared to the space for accommodating first component 22.
- second component 24 is advantageously shaped and adapted to fit properly within this space, thereby providing maximum possible heat exchange area and further taking advantage of the increased flow velocity of air through that zone.
- one preferred implementation of the vapor compression system in accordance with the present invention is a transcritical vapor compression system.
- a transcritical vapor compression system operates upon a refrigerant which does not condense in the first heat exchanger.
- a refrigerant of a transcritical vapor compression system is CO 2 .
- other refrigerants could be used well within the scope of the present invention to provide suitable vapor compression systems which would benefit from the heat exchanger arrangement of the present invention.
- Expansion device 18 can be any suitable expansion device for decreasing the pressure of refrigerant passing there through as is known to a person of skill in the art. Various known expansion devices could be utilized for this purpose.
- a pressure regulator such as that disclosed in WO 2006/101566 , is a particularly desirable type of expansion device for use in connection with the present invention. As used herein, the term expansion device is considered to include such a pressure regulator.
- Second heat exchanger 20 which performs the function of an evaporator, is shown as a single heat exchanger in the drawings. It should be appreciated that second heat exchanger 20 could also be provided in a plurality of components, as well, in the event that space for treatment of flow of air from the refrigerated space is particularly small and/or irregularly shaped.
- FIG. 3 shows refrigerant lines connecting from first heat exchanger 16 to expansion device 18 and then to second heat exchanger or evaporator 20. Refrigerant flows from evaporator 20 back to the suction inlet of compressor 14.
- the present invention provides for increased heat exchange efficiency due to increase in area of contact between the heat exchanger and the heat exchange medium. It should further be appreciated that the system of the present invention provides for enhanced utilization of space available for heat exchange, thereby providing more efficient operation of a vapor compression system as desired in accordance with the present invention.
- FIG. 2 shows an example with a two part heat exchanger.
- the refrigerant flow would be circuited first through component 24 and then through component 22 if the air flow was directed from front to back.
- the refrigerant flow would be circuited first through component 22 and then through component 24 if the air flow was from back to front.
- This concept is especially useful for transcritical vapor compression systems (such as using CO 2 ), where it is critically important for efficiency that the temperature of refrigerant leaving the heat rejecting heat exchanger be as close as possible to the heat sink fluid (typically air) entering the heat exchanger.
- the individual heat exchanger segments or components could also be circuited to be as counterflow as possible to further enhance this effect.
- the segments or components of the heat exchanger could be manufactured and shipped as one piece, or separately manufactured and connected during the unit assembly process.
- This type of a heat exchanger is particularly useful for applications where a low number of fins are used on the heat exchanger for reasons of fouling.
- the reduction in fins due to fouling concerns is offset by the additional heat exchanger tube or channel surface area.
- This heat exchanger could be a round tube plate fin, wire on tube, microchannel, or any other configuration.
