Description

Technical Field

[0001] This utility model relates to the field of wine cabinet refrigeration technology, and in particular to a flow guiding component and a wine cabinet. Background Technology

[0002] In the current wine cabinet technology field, mainstream airflow systems are mostly based on axial fans. However, this traditional design has revealed many limitations in practical applications, making it difficult to meet the growing functional demands of modern users. During use, because the axial fan's airflow direction is unidirectional, it creates an uneven airflow distribution inside the wine cabinet, resulting in significant temperature differences. When refrigerating red wine, the area near the fan is cooler, while the area further away is warmer, with a temperature difference of 5°C or even more. This temperature unevenness affects the storage quality of the red wine, accelerates spoilage, and negatively impacts the user experience.

[0003] Furthermore, because the axial fan duct cannot efficiently deliver cooling to all areas of the wine cabinet, the compressor needs to start frequently and run for extended periods to reach the set temperature, leading to a significant increase in energy consumption. This is especially true in the freezer compartment, where the existing ductwork is insufficient to meet the low-temperature requirements, forcing the equipment to consume more electricity to maintain the temperature, resulting in energy waste and increased operating costs for users. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, one of the objectives of this utility model is to provide a flow guiding component for a wine cabinet, which can guide airflow from both sides to reduce the temperature difference inside the wine cabinet.

[0005] The second objective of this utility model is to provide a wine cabinet whose airflow guiding component can guide cold air from both sides into the wine cabinet, so that the cold air in the wine cabinet is evenly distributed and indirectly reduces energy consumption.

[0006] One of the objectives of this utility model is achieved through the following technical solution:

[0007] A flow guide component for a wine cabinet includes:

[0008] A flow guide shroud has an air inlet cavity and a flow guide cavity. The air inlet cavity has an air inlet and an air guide outlet. The air inlet is used to guide airflow into the air inlet cavity, and the air guide outlet is connected to the flow guide cavity and is used to guide airflow into the flow guide cavity.

[0009] The air guide cavity has a first air outlet and a second air outlet, which are symmetrically distributed on both sides of the air guide shroud.

One end of the first flow guiding surface extends in an arc shape and is used to guide the airflow to the first air outlet. One end of the second flow guiding surface extends in an arc shape and is used to guide the airflow to the second air outlet.

[0011] A flow guide fan is installed in the air inlet cavity.

[0012] Furthermore, the flow guiding cavity has a first flow guiding cavity section and a second flow guiding cavity section, the first flow guiding cavity section and the second flow guiding cavity section are symmetrically distributed on both sides of the flow guiding shroud and are respectively connected to the air guide port; the first flow guiding surface is used to guide the airflow into the first flow guiding cavity section, and the second flow guiding surface is used to guide the airflow into the second flow guiding cavity section; the first air outlet is connected to the first flow guiding cavity section; the second air outlet is connected to the second flow guiding cavity section.

[0013] Furthermore, the first flow guiding cavity section is provided with a first heat insulation layer, which is laid on the cavity wall of the first flow guiding cavity section; the second flow guiding cavity section is provided with a second heat insulation layer, which is laid on the cavity wall of the second flow guiding cavity section.

[0014] Furthermore, the cavity wall of the first guide cavity has a third guide surface, which extends in an arc shape to the air inlet and is used to guide airflow into the first guide cavity; the cavity wall of the second guide cavity has a fourth guide surface, which extends in an arc shape to the air inlet and is used to guide airflow into the second guide cavity.

[0015] Furthermore, the flow guide shroud is provided with two partitions, which are spaced apart. One partition is spaced apart from the inner wall of the flow guide shroud to form the first flow guide cavity segment; the other partition is spaced apart from the inner wall of the flow guide shroud to form the second flow guide cavity segment; one end of the partition is connected to the bottom wall of the flow guide cavity, and the other end of the partition extends to the bottom of the air inlet cavity.

[0016] Furthermore, the air guide shroud is provided with a mounting base, and the air inlet and the air guide port are formed in the mounting base; the bottom of the mounting base is connected to the top of the two partitions; the air guide fan is mounted on the mounting base.

[0017] Furthermore, both sides of the mounting base have guiding arc surfaces, one end of each of the two guiding arc surfaces extends to the air vent, and the other end of each of the two guiding arc surfaces extends to the first flow guide cavity and the second flow guide cavity, respectively; the two guiding arc surfaces are respectively formed as the third flow guide surface and the fourth flow guide surface.

[0018] Furthermore, the air guide includes a housing and a cover plate, the cover plate being detachably connected to the housing and enclosing the air guide cavity; the air inlet is located on the top of the housing, and the first air outlet and the second air outlet are located on the cover plate;

[0019] The top of the cover plate is provided with a first guide plate and a second guide plate, the first guide plate and the second guide plate are respectively arranged in an arc shape; the first guide surface is formed on the first guide plate and the second guide surface is formed on the second guide plate.

[0020] The technical solution adopted for the second objective of this utility model is:

[0021] A wine cabinet includes a cabinet body, a refrigeration component, and a flow guiding component for the wine cabinet; the cabinet body has a refrigerator compartment, and the flow guiding component for the wine cabinet is used to guide cold airflow into the refrigerator compartment.

[0022] Furthermore, the refrigeration assembly includes an evaporator connected to the outer periphery of the air guide and communicating with the air inlet; the first air outlet and the second air outlet are communicating with the refrigerator compartment;

[0023] The refrigerator compartment has multiple support plates, which are spaced apart in the refrigerator compartment. Multiple first air outlets and multiple second air outlets are spaced apart between two adjacent support plates.

[0024] The bottom of the refrigerator compartment has a third air outlet, which is connected to the evaporator.

[0025] In summary, the guide fan and wine cabinet for wine cabinets provided by this utility model have the following technical effects:

[0026] In practical use, the cold airflow enters the air inlet cavity under the guidance of the guide fan, and then exits from the air outlet into the guide cavity. Since the guide cavity is equipped with two staggered first and second guide surfaces, both of which extend in an arc shape, when the cold airflow enters the guide cavity from the air outlet, the arc-shaped protrusion of the first guide surface forces the airflow to deflect to one side (such as the direction of the first air outlet), flowing from the top to the bottom of the first air outlet along the curved surface. Similarly, the arc-shaped protrusion of the second guide surface bends to the other side (the direction of the second air outlet), guiding the remaining airflow to deflect to the right, flowing from the top to the bottom of the second air outlet along the curved surface. This allows the cold airflow to be exited from both sides of the guide cavity into the refrigerator compartment of the wine cabinet, so that the cold airflow in the refrigerator compartment can be evenly distributed, reducing the temperature difference in the refrigerator compartment and improving the wine refrigeration effect. At the same time, due to the low temperature difference, the refrigerator compartment can reach the predetermined refrigeration temperature as quickly as possible, indirectly reducing energy consumption.

[0041] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0042] Example 1,

[0043] See Figure 1 and Figure 4This utility model discloses a flow guiding component for a wine cabinet, including a flow guiding hood 10. The flow guiding hood 10 has an air inlet cavity 11 and a flow guiding cavity 12. The air inlet cavity 11 has an air inlet 111 and an air guide 112. The air inlet 111 is used to guide airflow into the air inlet cavity 11, and the air guide 112 is connected to the flow guiding cavity 12 and is used to guide airflow into the flow guiding cavity 12. The flow guiding cavity 12 has a first air outlet 121 and a second air outlet 122. The first air outlet 121 and the second air outlet 122 are connected to each other. The inlets 122 are symmetrically distributed on both sides of the air guide shroud 10; the cavity wall of the air guide cavity 12 is provided with a first air guide surface 123 and a second air guide surface 124, which are staggered; one end of the first air guide surface 123 extends in an arc shape and is used to guide the airflow to the first air outlet 121; one end of the second air guide surface 124 extends in an arc shape and is used to guide the airflow to the second air outlet 122; the air guide fan 20 is installed in the air inlet cavity 11.

[0044] Based on the above structure, during assembly (such as...) Figure 3 As shown, the air inlet cavity 11 can be positioned above the air guide shroud 10, and the air guide port 112 is located above the air inlet cavity 11, opposite to and spaced apart from the first air guide surface 123 and the second air guide surface 124 on the inner wall of the air guide cavity 12. Simultaneously, the arc extension directions of the first air guide surface 123 and the second air guide surface 124 are opposite, extending to the first air outlet 121 and the second air outlet 122 located on the left and right sides of the air guide cavity 12, respectively. Thus, when the air guide fan 20 guides the cold airflow into the air inlet cavity 11, the cold airflow in the air inlet cavity 11 is blown into the air guide cavity 12 from the air guide port 112 under the action of the air guide fan 20.

[0045] At this time, since the first guide surface 123 and the second guide surface 124 are arc-shaped and extend in opposite directions, when the airflow enters the guide cavity 12, the arc-shaped protrusion of the first guide surface 123 will force the airflow to deflect to one side (such as the direction of the first air outlet 121), flowing from top to bottom along the curved surface to the first air outlet 121; similarly, the arc-shaped protrusion of the second guide surface 124 bends to the other side (the direction of the second air outlet 122), guiding the remaining airflow to deflect to the right, flowing from top to bottom along the curved surface to the second air outlet 122. In this way, after the airflow is introduced through the air outlet 112, it can only flow on the arc-shaped surface, adhering to the arc-shaped first guide surface 123 and the second guide surface 124, deflecting to both sides, and then flowing from top to bottom to the corresponding first air outlet 121 and second air outlet 122.

[0046] Furthermore, due to the relatively high density of the cold airflow, it tends to move downwards naturally within the guide cavity 12 under the influence of gravity. Thus, while the arc-shaped first guide surface 123 and the arc-shaped second guide surface guide the airflow to both sides, gravity causes the airflow to move downwards along the two guide surfaces, achieving top-down flow guidance. This allows the cold airflow to ultimately exit from the first air outlet 121 and the second air outlet 122 on the left and right sides. By using two staggered and arc-shaped first guide surfaces 123 and second guide surfaces 124, the single cold airflow is divided into two independent and uniform airflows, avoiding concentration in a certain area.

[0047] Therefore, when the airflow guiding component for wine cabinets in this embodiment is applied to refrigeration equipment such as wine cabinets and refrigerators, the airflow guiding hood 10 can be installed on the outer periphery of the refrigeration chamber 31, and the first air outlet 121 and the second air outlet 122 can be connected to the interior of the refrigeration chamber 31 respectively. The airflow guiding fan 20 can be connected to the cooling components (such as evaporator 40 or condenser) inside the equipment, so that the airflow guiding fan 20 can guide the cold airflow into the airflow guiding cavity 12, and through the two intersecting and arc-shaped airflow guiding cavities within the airflow guiding cavity 12... The extended first guide surface 123 and second guide surface 124 divide the single cold airflow into two independent and uniform airflows, which are blown into the refrigerator compartment 31 through the first air outlet 121 and the second air outlet 122 on both sides, so that the cold airflow is evenly introduced from both sides of the refrigerator compartment 31, making the temperature field of the refrigerator compartment 31 more balanced, reducing temperature fluctuations, reducing the temperature difference in the refrigerator compartment 31, improving the refrigeration effect, and shortening the time to reach the predetermined temperature, thereby reducing the operating frequency of the refrigeration equipment and saving energy.

[0048] It should be noted that the flow guide shroud 10 in this embodiment can be formed by two or three or more plate segments or shells 15, so that a flow guide cavity 12 is formed inside it; and the first flow guide surface 123 and the second flow guide surface 124 can be formed by setting two interlocking arc-shaped plates inside the flow guide shroud 10, so that the inner wall of the flow guide shroud 10 has the first flow guide surface 123 and the second flow guide surface 124; of course, it can also be formed by mechanically cutting inside the flow guide shroud 10, so that the two interlocking first flow guide surfaces 123 and the second flow guide surfaces 124 are formed inside it.

[0049] In addition, the air inlet cavity 11 can be formed by setting a hollow shell 15 inside the air guide 10 and installing it into the air guide 10. The hollow part of the shell 15 can then be used to form the air inlet cavity 11. Alternatively, multiple partitions 13 can be used to enclose and separate a separate cavity inside the air guide 10 to form the air inlet cavity 11.

[0050] More specifically, the guide fan 20 in this embodiment can be an existing axial fan, centrifugal fan or cross-flow fan, etc. It can be connected to the air inlet 111 of the guide shroud 10 by means of connectors (such as screws or bolts), or it can be directly installed in the air inlet cavity 11. The specific configuration can be set according to actual needs.

[0051] Furthermore, the flow guiding cavity 12 has a first flow guiding cavity segment 125 and a second flow guiding cavity segment 126. The first flow guiding cavity segment 125 and the second flow guiding cavity segment 126 are symmetrically distributed on both sides of the flow guiding shroud 10 and are respectively connected to the air guide port 112. The first flow guiding surface 123 is used to guide the airflow into the first flow guiding cavity segment 125, and the second flow guiding surface 124 is used to guide the airflow into the second flow guiding cavity segment 126. The first air outlet 121 is connected to the first flow guiding cavity segment 125, and the second air outlet 122 is connected to the second flow guiding cavity segment 126.

[0052] Based on this structure (such as) Figure 3 As shown), during assembly, two independent first guide cavity 12 segments 125 and second guide cavity 12 segments 126 can be separated within the guide cavity 12. Air outlets 112 are connected to both the first guide cavity 12 segments 125 and the second guide cavity 12 segments 126. Specifically, the first air outlet 121 is connected to the first guide cavity 12 segment 125, and the second air outlet 122 is connected to the second guide cavity 12 segment 126. Simultaneously, the first guide surface 123 can be formed above the first guide cavity 12 segment 125, and the second guide surface 124 can be formed above the second guide cavity 12 segment 126. Above the 126th section of the flow guide cavity, the cold airflow at the air guide 112 can be guided by the first flow guide surface 123 and the second flow guide surface 124 respectively into the two relatively independent first flow guide cavity 125 and second flow guide cavity 126, so as to guide the cold airflow to flow along a specific path and concentrate it to both sides of the flow guide shroud 10, and then exit through the first air outlet 121 and the second air outlet 122 respectively. Compared with the air outlet on both sides of a single flow guide cavity 12, the airflow guidance is more accurate, the airflow turbulence is reduced, and the flow guiding effect is better.

[0053] Furthermore, through two independent first and second guide chambers 12 segments 126, the airflow entering the air inlet chamber 11 is forcibly "distributed" to two channels, preventing airflows from different chamber segments from mixing or interfering with each other at the source. Simultaneously, the two independent first guide chambers 12 segments 125 and second guide chambers 12 segments 126 can be adjusted independently to achieve a more uniform airflow distribution. For example, the size of the air outlets and the angle of the guide surfaces in different chamber segments can be adjusted, allowing the cold airflow to diffuse more evenly within the wine cooler compartment and reducing temperature differences.

[0054] It should be noted that the flow guiding cavity 12 in this embodiment can be formed by integrally forming two independent cavity segments on the left and right sides of the flow guiding cover 10, or by setting a partition 13 or baffle inside the flow guiding cover 10 to divide its interior into two independent cavity segments.

[0055] Furthermore, a first insulation layer is provided inside the first flow guiding cavity 12 segment 125, and the first insulation layer is laid on the cavity wall of the first flow guiding cavity 12 segment 125; a second insulation layer is provided inside the second flow guiding cavity 12 segment 126, and the second insulation layer is laid on the cavity wall of the second flow guiding cavity 12 segment 126.

[0056] Based on this structure, by setting a first insulation layer and a second insulation layer in the first flow guide cavity 12 segment 125 or the second flow guide cavity 12 segment 126 respectively, heat exchange between the cold airflow in the two flow guide cavities 12 and the outside environment (such as other areas inside the cabinet or the environment) can be effectively prevented. This allows the cooling capacity to be concentrated on the target area (such as the cold storage compartment), improving refrigeration efficiency and reducing energy consumption. At the same time, the presence of the insulation layer can also prevent condensation or dew formation on the cavity walls due to low temperature, reducing corrosion to the internal structure of the equipment. It also prevents external heat from interfering with the airflow temperature, ensuring a constant airflow temperature in the flow guide cavity 12 and improving temperature control.

[0057] It should be noted that the first and second insulation layers can be made of existing insulation cotton (such as glass wool, rock wool) or insulation board (such as extruded polystyrene (XPS) board), which can be fixed to the inner wall of the two flow channels 12 sections by adhesive or connectors; or polyurethane (PU) foam can be used and sprayed onto the inner wall of the two flow channels 12 sections.

[0058] Furthermore, the cavity wall of the first guide cavity 12 segment 125 has a third guide surface 141, which extends in an arc shape to the air guide port 112 and is used to guide the airflow into the first guide cavity 12 segment 125; the cavity wall of the second guide cavity 12 has a fourth guide surface 142, which extends in an arc shape to the air guide port 112 and is used to guide the airflow into the second guide cavity 12 segment 126.

[0059] Based on this structure, during assembly, the third guide surface 141 and the fourth guide surface 142 can extend in an arc shape to both ends of the air inlet 112. Specifically, the third guide surface 141 is positioned opposite to the first guide surface 123, and the arc-shaped concave surface of the first guide surface 123 matches the arc-shaped convex surface of the third guide surface 141. The fourth guide surface 142 is positioned opposite to the second guide surface 124, and the arc-shaped concave surface of the second guide surface 124 matches the arc-shaped convex surface of the fourth guide surface 142. In this way, the first and second guide surfaces 124 form an upper surface arc-shaped constraint, "pressing" the airflow into the inlet of the first guide cavity 12 segment 125 and the second guide cavity 12 segment 126; while the third and fourth guide surfaces 142 (cavity walls) form a side surface arc-shaped constraint, "enveloping" the airflow. The first and second guide cavities 12 sections 126 allow the airflow to smoothly transition through the cooperation of multiple arc surfaces, reducing the resistance during flow and enabling the airflow to be quickly introduced into the first and second guide cavities 12 sections 126, achieving low-resistance and high-efficiency airflow transmission.

[0060] Preferably, in this embodiment, two partitions 13 are provided inside the flow guide shroud 10, and the two partitions 13 are spaced apart. One end of the partition 13 is connected to the bottom wall of the flow guide cavity 12, and the other end of the partition 13 extends to the bottom of the air inlet cavity 11. In this way, the partition 13 is spaced apart from the inner wall of the flow guide shroud 10 to form the first flow guide cavity 12 segment 125, and the partition 13 is spaced apart from the inner wall of the flow guide shroud 10 to form the second flow guide cavity 12 segment 126, so that two relatively independent flow guide cavity segments 12 are formed inside the flow guide cavity 12.

[0061] Furthermore, a mounting base 14 is provided inside the air guide shroud 10, and an air inlet 11 and an air guide 112 are formed in the mounting base 14; the bottom of the mounting base 14 is connected to the top of the two partitions 13, and the air guide fan 20 is mounted on the mounting base 14.

[0062] Specifically, a mounting base 14 is provided inside the air guide shroud 10, and an air inlet 11 and an air guide 112 are formed in the mounting base 14. Specifically, the air guide 112 can be located above the mounting base 14, and the air guide fan 20 is installed by using the mounting base 14 as a supporting component, so that the airflow from the outlet of the air guide fan 20 can be directly introduced into the first and second air guide cavities 12 sections 126 below through the air guide 112 above the mounting base 14, shortening the airflow transmission path and reducing pressure loss caused by long-distance transportation.

[0063] More specifically, during installation, the two sides of the mounting base 14 can be spaced apart from the two sides of the flow guide shroud 10, and the bottom can be connected to the top of the two partitions 13. In this way, after the mounting base 14 is connected to the partitions 13, the two sides of the mounting base 14 and the partitions 13 together form a symmetrical double-cavity structure with the gap between them and the inner wall of the flow guide shroud 10. When the airflow output by the fan is split at the air guide 112, the flow channels on both sides are basically the same, which improves the balance of flow distribution and avoids the "flow deviation" phenomenon caused by the asymmetry of the flow channels.

[0064] Preferably, in this example, guide arc surfaces are provided on both sides of the mounting base 14, and one end of each guide arc surface extends to the air vent 112, while the other end extends to the first guide cavity 12 segment 125 and the second guide cavity 12 segment 126, respectively, so that the two guide arc surfaces are respectively formed into the third guide surface 141 and the fourth guide surface 142.

[0065] More specifically, in this embodiment, the air guide shroud 10 includes a housing 15 and a cover plate 16. The cover plate 16 and the housing 15 are detachably connected so that the two together enclose an air guide cavity 12. An air inlet 111 is provided on the top of the housing 15, and a first air outlet 121 and a second air outlet 122 are provided on the cover plate 16. A first air guide plate 161 and a second air guide plate 162 are provided on the top of the cover plate 16. The first air guide plate 161 and the second air guide plate 162 are respectively arranged in an arc shape and are staggered, so that the top of the air guide cavity 12 forms an arc-shaped first air guide surface 123 and a second air guide plate 162.

[0066] It should be noted that, based on this, the mounting base 14 can be clamped between the housing 15 and the cover plate 16, and the air inlet cavity 11 on the mounting base 14 is connected to the air inlet 111, so that the guide cavity 12 has an air inlet cavity 11, and the air inlet 111 is connected to the air inlet cavity 11.

[0067] Example 2,

[0068] A wine cabinet includes a cabinet body 30, a refrigeration component, and a flow guiding component for the wine cabinet in Embodiment 1. The cabinet body 30 has a refrigerator compartment 31, and the flow guiding component for the wine cabinet is used to guide the cold airflow into the refrigerator compartment 31.

[0069] Based on this structure, the air guide shroud 10 can be installed on the outer periphery of the refrigerator compartment 31, and the first air outlet 121 and the second air outlet 122 can be connected to the interior of the refrigerator compartment 31 respectively. The air guide fan 20 can be connected to the internal cooling components (such as the evaporator 40 or the condenser) of the equipment. The air guide fan 20 guides the cold airflow into the air guide cavity 12. Through the two intersecting and arc-shaped first air guide surfaces 123 and 124 in the air guide cavity 12, the single cold airflow is divided into two independent and uniform airflows, which are blown into the refrigerator compartment 31 through the first air outlet 121 and the second air outlet 122 on both sides respectively. This makes the cold airflow evenly introduced from both sides of the refrigerator compartment 31, making the temperature field of the refrigerator compartment 31 more uniform, reducing temperature fluctuations, reducing the temperature difference in the refrigerator compartment 31, improving the refrigeration effect, and shortening the time to reach the predetermined temperature, thereby reducing the operating frequency of the refrigeration equipment and saving energy.

[0070] Furthermore, the refrigeration assembly includes an evaporator 40, which is connected to the outer periphery of the air guide shroud 10 and communicates with the air inlet 111; the first air outlet 121 and the second air outlet 122 communicate with the refrigerator compartment 31; the refrigerator compartment 31 has multiple support plates 311, which are spaced apart in the refrigerator compartment 31, and multiple first air outlets 121 and multiple second air outlets 122 are spaced apart between two adjacent support plates 311; the bottom of the refrigerator compartment 31 has a third air outlet 312, which communicates with the evaporator 40.

[0071] Specifically, the evaporator 40 is connected to the outer periphery of the air guide shroud 10 and communicates with the air inlet 111, so that the cold air released by the evaporator 40 can be directly guided to the air inlet 111 by the air guide fan 20, and blown into the air guide cavity 12 through the air guide port 112 of the air inlet cavity 11. Then, it is directly introduced into the refrigerator compartment 31 through the first air outlet 121 and the second air outlet 122 on both sides of the air guide cavity 12, which reduces the loss of cold air during the flow of cold air, saves energy, and improves the cooling effect.

[0072] In addition, multiple support plates 311 divide the cold storage compartment 31 into multiple independent temperature zones. Each layer has multiple first and second air outlets 122 between adjacent support plates 311, forming a horizontal cross-flow pattern. Within the same layer, the airflow from the air outlets on both sides flows in opposite directions, forming a counter-flow layer below the support plates 311, forcing the air to diffuse laterally. At the same time, the air outlets on the upper and lower layers are staggered to avoid short-circuiting of the vertical airflow, making the temperature distribution of each temperature zone more uniform and reducing temperature differences.

[0073] More specifically, since the third air outlet 312 at the bottom of the refrigerator compartment 31 is connected to the inlet of the evaporator 40, a closed-loop circulation of "air supply-heat exchange-return air" is formed. When the low-temperature airflow diffuses horizontally from the upper air outlet to each layer, it absorbs heat and rises in temperature, and its density decreases, so it naturally rises. However, the negative pressure suction effect of the bottom third air outlet 312 (generated by the guide fan 20) forces the high-temperature air to flow downwards. When the high-temperature air flows back to the inlet of the evaporator 40 through the bottom third air outlet 312, the temperature is higher (close to the actual load temperature of the refrigerator compartment 31), and the heat exchange temperature difference with the evaporator 40 is greater. This allows the evaporator 40 to absorb more heat per unit time, improving the cooling efficiency of the evaporator 40 and saving energy.
