[0029] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.

[0030] In the description of the embodiments of the present application, "upper", "lower", "top", "bottom", orientation or position relationship is based on the attached Figure 1 It should be understood that these directional terms are only used to facilitate the description of this application and simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting this application. For example, please refer to Figure 1 , the up and down directions are the directions indicated by arrow R1 in the figure.

[0031] In the related art, during normal refrigeration, the refrigerant discharged from the compressor enters the evaporator through the condenser body for cooling. When the evaporator is defrosting, the refrigerant discharged from the compressor, which is at a higher temperature, enters the evaporator pipe to defrost the evaporator surface. The water melted during the evaporator defrosting process is collected in the first water receiving device. However, since the water melted during the defrosting process is relatively low in temperature, when the first water receiving device receives the water melted during the defrosting process, the water temperature in the first water receiving device is relatively low and evaporates slowly. Therefore, a bypass pipe needs to be placed in the first water receiving device to accelerate the evaporation of the water in the first water receiving device and reduce the possibility of water overflowing from the first water receiving device. However, the condensing device in the related art is only provided with a refrigeration input pipe. For the manufacturer of the refrigeration system, it is necessary to match the bypass pipe of the corresponding specifications with the refrigeration input pipe of the condensing device. The bypass pipe must be able to be connected to the tee pipe and be partially placed in the first water receiving device. The bypass pipe may need to be processed into a specific shape so that the bypass pipe connected to the tee pipe can be placed in the first water receiving device. For the manufacturer of the refrigeration system, such processing equipment may not be available. Therefore, the condensing device in the related art is only provided with a refrigeration input pipe, which increases the workload of the manufacturer of the refrigeration system to assemble the condensing device to the refrigeration system. It may even be complicated and labor-intensive due to the lack of suitable equipment to adaptively process the shape of the bypass pipe.

[0032] In view of this, the present application embodiment provides a refrigeration system, please refer to Figure 1 and Figure 2 The refrigeration system includes a compressor 1, a condensing device 2, an evaporator 10 and a first water receiving device.

[0033] In one embodiment, please refer to Figure 1 and Figure 2 The refrigerant discharged from the compressor 1 flows to the evaporator 10 through the condensing device 2 and flows back to the compressor 1 through the output end of the evaporator 10.

[0034] In one embodiment, please refer to Figure 1 and Figure 2 The first water receiving device is used to collect water generated during the defrosting process of the evaporator 10.

[0035] Illustratively, the first water receiving device may be a first water receiving tray.

[0036] Exemplarily, the water in the first water receiving device is no longer discharged outside the first water receiving device so that the water generated during the defrosting process of the evaporator 10 is gathered in the first water receiving device.

[0037] For example, a proper amount of water in the first water receiving device may be discharged outside the first water receiving device, so that water generated during the defrosting process of the evaporator 10 is gathered in the first water receiving device as much as possible.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 The condensing device 2 includes a condenser body 21, a refrigeration output pipe 22, a refrigeration input pipe 23, a bypass pipe 24 and a three-way pipe 6. The refrigeration output pipe 22 is connected to the outlet of the condenser body 21, and the refrigeration input pipe 23 is connected to the inlet of the condenser body 21. The refrigeration input pipe 23 is used to be at least partially placed in the first water receiving device to heat the water in the first water receiving device. The bypass pipe 24 is used to be at least partially placed in the first water receiving device to heat the water in the first water receiving device. The refrigeration input pipe 23, the condenser body 21 and the refrigeration output pipe 22 are all connected in parallel with the bypass pipe 24. The three-way pipe 6 has a first interface 61, a second interface 62 and a third interface 63. The first interface 61 is used to receive the refrigerant discharged from the compressor 1, the second interface 62 is connected to the refrigeration input pipe 23, and the third interface 63 is connected to the bypass pipe 24.

[0039] For example, see Figure 1 and Figure 2 , the first interface 61 is connected to the output end of the compressor 1 .

[0040] For example, see Figure 1 and Figure 2 The evaporator 10 is used to receive the refrigerant output from the refrigeration output pipe 22 to perform evaporative cooling. The evaporator 10 is used to receive the refrigerant output from the bypass pipe 24 to defrost the evaporator 10.

[0041] Illustratively, during the refrigeration process, the higher temperature refrigerant discharged from the compressor 1 flows to the evaporator 10 through the refrigeration input pipe 23 , the condenser body 21 and the refrigeration output pipe 22 to expand and absorb heat for refrigeration, and then returns to the compressor 1 .

[0042] For example, during the defrosting process, the higher temperature refrigerant discharged from the compressor 1 enters the evaporator 10 through the bypass pipe 24 for defrosting. The refrigerant does not pass through the condenser body 21. The temperature of the refrigerant entering the evaporator 10 is higher, which can better defrost the evaporator 10.

[0043] For example, see Figure 1 and Figure 2The refrigerant input pipe 23 and the bypass pipe 24 are both at least partially located in the first water receiving device. During the refrigeration process of the evaporator 10, the refrigerant discharged from the compressor 1 enters the condenser body 21 through the refrigerant input pipe 23. Since the refrigerant input pipe 23 is at least partially located in the first water receiving device, the refrigerant with a higher temperature in the refrigerant input pipe 23 can heat the water in the first water receiving device, accelerating the evaporation of the water in the first water receiving device, thereby reducing the possibility of water overflowing from the first water receiving device. During the defrosting process of the evaporator 10, the refrigerant discharged from the compressor 1 enters the evaporator 10 through the bypass pipe 24. The refrigerant discharged from the compressor 1 does not pass through the condenser for condensation, and the higher temperature refrigerant enters the evaporator 10 to defrost the evaporator 10. Since the bypass pipe 24 is at least partially located in the first water receiving device, the refrigerant with a higher temperature in the bypass pipe 24 can heat the water in the first water receiving device, accelerating the evaporation of the water in the first water receiving device, thereby reducing the possibility of water overflowing from the first water receiving device. Therefore, the refrigeration input pipe 23 and the bypass pipe 24 are at least partially located in the first water receiving device. Whether in the normal refrigeration process or in the defrosting process, the water in the first water receiving device can be better heated and evaporation can be accelerated, thereby reducing the possibility of water overflow in the first water receiving device.

[0044] For example, the cooling device comprising the cooling input pipe 23, the bypass pipe 24, the condenser body 21, and the cooling output pipe 22 can be connected into a single unit via the tee pipe 6. The tee pipe 6 and the cooling device can be assembled after being delivered as a single unit. For example, the cooling device comprising the cooling input pipe 23, the bypass pipe 24, the condenser body 21, and the cooling output pipe 22 can be connected into a single unit via the tee pipe 6. The tee pipe 6 and the cooling device can be assembled after being delivered as a single unit. Upon receipt by the main unit assembler, there is no need to install the bypass pipe 24 between the tee pipe 6.

[0045] In the embodiment of the present application, the bypass pipe 24 and the refrigerant input pipe 23 are connected to form a whole by the tee pipe 6. The manufacturer of the condensing device 2 already needs to process the refrigerant input pipe 23 into a corresponding shape. Accordingly, the manufacturer of the condensing device 2 can conveniently pre-process the bypass pipe 24 into a corresponding shape and connect it to the tee pipe 6, so that the bypass pipe 24 connected to the tee pipe 6 can more conveniently place at least a portion of its structure into the first water receiving device. The condensing device 2 having the tee pipe 6 and the refrigerant input pipe 23 and bypass pipe 24 connected to the tee pipe 6 is processed as a whole by the manufacturer of the condensing device 2. The manufacturer of the refrigeration system can directly assemble the condensing device 2 having the tee pipe 6 and the refrigerant input pipe 23 and bypass pipe 24 connected to the tee pipe 6 into the refrigeration system as a whole without the need for additional processing and assembly of the corresponding bypass pipe 24. This reduces the assembly workload of the condensing device 2 into the refrigeration system and facilitates relatively rapid assembly of the condensing device 2 into the refrigeration system.

[0046] In one embodiment, please refer to Figure 1 and Figure 2 The three-way pipe 6, the refrigeration input pipe 23 and the bypass pipe 24 are designed as an integrated whole.

[0047] The integrated design of the three-way pipe 6, the cooling input pipe 23, and the bypass pipe 24 means that the three-way pipe 6 is non-detachably connected to the cooling input pipe 23 and the bypass pipe 24. The cooling input pipe 23 is non-detachably connected to the three-way pipe 6, and the bypass pipe 24 is non-detachably connected to the three-way pipe 6.

[0048] In the embodiment of the present application, the three-way pipe 6, the refrigeration input pipe 23 and the bypass pipe 24 are integrated into one design, so that the three-way pipe 6, the refrigeration input pipe 23 and the bypass pipe 24 cannot be disassembled, and there is no need to fold the three-way pipe 6, the refrigeration input pipe 23 and the bypass pipe 24, which is beneficial to reducing the assembly workload of the manufacturer of the refrigeration system.

[0049] It is understood that the specific structure of the condensing device 2 is not limited, as long as the condensing device 2, including the tee pipe 6 and the refrigerant input pipe 23 and bypass pipe 24 connected to the tee pipe 6, is supplied as a whole and assembled into the refrigeration system. For example, the tee pipe 6 can be detachably connected to the refrigerant input pipe 23, and the tee pipe 6 can be detachably connected to the bypass pipe 24.

[0050] In one embodiment, please refer to Figure 1 and Figure 2 The three-way pipe 6 is welded to the refrigeration input pipe 23 and the bypass pipe 24 respectively.

[0051] Exemplarily, the tee pipe 6 is welded to the bypass pipe 24 at the third interface 63 .

[0052] Exemplarily, the tee pipe 6 is welded to the refrigeration input pipe 23 at the second interface 62 .

[0053] In the embodiment of the present application, the three-way pipe 6, the refrigeration input pipe 23 and the bypass pipe 24 are integrated into an integrated design by welding, and the three-way pipe 6, the refrigeration input pipe 23 and the bypass pipe 24 are connected into an inseparable whole, so that the condensing device 2 having the three-way pipe 6 and the refrigeration input pipe 23 and the bypass pipe 24 connected to the three-way pipe 6 can be assembled into the refrigeration system as a whole.

[0054] In some embodiments, see Figure 1 and Figure 2 The refrigeration input pipe 23 has a first water removal section 231 for heating the water in the first water receiving device, and the bypass pipe 24 has a second water removal section 241 for heating the water in the first water receiving device.

[0055] Exemplarily, the first water removal section 231 is located in the first water receiving device.

[0056] Exemplarily, the second water removal section 241 is located in the first water receiving device.

[0057] The first water removal section 231 refers to a portion of the refrigeration input pipe 23 that can be placed in the first water receiving device and heats and evaporates the water in the first water receiving device through a refrigerant with a relatively high temperature.

[0058] The second water removal section 241 refers to a portion of the bypass pipe 24 that can be placed in the first water receiving device and heats and evaporates the water in the first water receiving device through a refrigerant with a relatively high temperature.

[0059] In an embodiment of the present application, the first water removal section 231 is located in the first water receiving device, and the second water removal section 241 is located in the first water receiving device. The water in the first water receiving device is heated and evaporated by the first water removal section 231 and / or the second water removal section 241, thereby reducing the possibility of water overflowing from the first water receiving device.

[0060] In some embodiments, see Figure 1 and Figure 2 The refrigeration input pipe 23 has a first dewatering section for heating the water in the first water receiving device, and the bypass pipe 24 has a second dewatering section for heating the water in the first water receiving device, and the second dewatering section is located above the first dewatering section.

[0061] In the embodiment of the present application, during the refrigeration process, water vapor condenses into frost on the surface of the evaporator 10. The amount of water generated during the refrigeration process is relatively small, and accordingly, less water is collected in the first water receiving device. The second water removal section 241 is located above the first water removal section 231, so that the first water removal section 231 of the refrigeration input pipe 23 is closer to the bottom of the first water receiving device. When the water in the first water receiving device is relatively small, the water in the first water receiving device can be heated well. During the defrosting process, the frost on the surface of the evaporator 10 melts into water, so that the amount of water collected in the first water receiving device is relatively large. The second water removal section 241 is located above the first water removal section 231, so that the first water removal section 231 is closer to the water surface in the first water receiving device when the amount of water in the first water receiving device is relatively large, thereby quickly heating and evaporating the surface water in the first water receiving device, reducing the possibility of water overflowing from the first water receiving device.

[0062] It is understood that the specific arrangement of the first dewatering section 231 and the second dewatering section 241 is not limited. For example, the first dewatering section 231 and the second dewatering section 241 can be arranged in a horizontal direction. For example, the first dewatering section 231 can be located above the second dewatering section 241.

[0063] In some embodiments, see Figure 1 and Figure 2 The condensing device 2 further includes at least one vibration absorber 4 spanning the first water removal section 231 and the second water removal section 241 , and each of the vibration absorbers 4 is sleeved on the outer side of the first water removal section 231 and the outer side of the second water removal section 241 .

[0064] The vibration absorber 4 is arranged across the first water removal section 231 and the second water removal section 241 . One vibration absorber 4 can reduce vibrations of both the first water removal section 231 and the second water removal section 241 .

[0065] Exemplarily, the shock absorber 4 may be in contact with the first water receiving device.

[0066] Illustratively, the shock absorber 4 may be a rubber sleeve or a silicone sleeve.

[0067] In the embodiment of the present application, since the bypass pipe 24 and the refrigeration input pipe 23 of the condensing device 2 are connected into a whole through the three-way pipe 6, the vibration damper 4 can be installed on the first dewatering section 231 and the second dewatering section 241 by the manufacturer of the condensing device during the production process of the condensing device, thereby reducing the assembly workload of the refrigeration system manufacturer. By having the vibration damper 4 straddle the first dewatering section 231 and the second dewatering section 241, the number of vibration dampers 4 can be reduced, and the workload of installing the vibration damper 4 can be reduced. Each vibration damper 4 is sleeved on the outside of the first dewatering section 231 and the second dewatering section 241, alleviating the impact vibration of the first water receiving device in direct contact with the first dewatering section 231 and the second dewatering section 241 under the action of the vibration of the operation of the compressor 1, which is conducive to suppressing the resonance of the first water receiving device with the first dewatering section 231 and the second dewatering section 241 to generate noise.

[0068] It is understood that the arrangement of the vibration absorber 4 is not limited. For example, the first dewatering section 231 and the second dewatering section 241 may each be provided with a vibration absorber 4, with at least one vibration absorber 4 provided on the first dewatering section 231 and at least one vibration absorber 4 provided on the second dewatering section 241.

[0069] In some embodiments, see Figure 1 and Figure 2 The number of the vibration absorbers 4 is at least two, and at least two of the vibration absorbers 4 are arranged at intervals.

[0070] The at least two vibration absorbers 4 can be two or more. For example, the number of the vibration absorbers 4 can be two, three, four or five.

[0071] It should be noted that the two shock absorbers 4 are arranged at intervals, which means that the two shock absorbers 4 are spaced apart by a certain distance.

[0072] In the embodiment of the present application, by arranging at least two vibration dampers 4 at intervals, the first water removal section 231 and the second water removal section 241 can be spaced as far as possible from the first water receiving device with fewer vibration dampers 4, thereby reducing the possibility of the first water receiving device contacting and vibrating with part of the first water removal section 231 and the second water removal section 241 under the vibration of the operation of the compressor 1.

[0073] It is understandable that there is no limit to the number of the shock absorbers 4. For example, the number of the shock absorber 4 can be one.

[0074] In some embodiments, see Figure 1 and Figure 2 The condensing device 2 further includes a main pipe 5. One end of the main pipe 5 is connected to the output end of the compressor 1 to receive the refrigerant discharged from the compressor 1. The first interface 61 is connected to the other end of the main pipe 5.

[0075] Exemplarily, the main pipe 5 may be a straight pipe.

[0076] In the embodiment of the present application, one end of the main pipe 5 is connected to the output end of the compressor 1 to receive the refrigerant discharged from the compressor 1, and the refrigerant in the main pipe 5 is diverted through the tee pipe 6. The first port 61 is connected to the other end of the main pipe 5, receives the refrigerant discharged from the compressor 1 through the main pipe 5, and transports the refrigerant to the tee pipe 6 for diversion. By adapting the position of the main pipe 5 to the position of the tee pipe 6, the position of the tee pipe 6 is more flexible.

[0077] It is understandable that the structure of the refrigeration system is not limited. For example, the condensing device 2 may not be provided with the main pipe 5 and the tee according to actual needs.

[0078] In some embodiments, see Figure 1 and Figure 2 The refrigeration system further includes a switching valve 7 and a throttle 8. The switching valve 7 is connected between the third interface 63 and the input end of the evaporator 10, and the switching valve 7 is connected in series with the bypass pipe 24. The throttle 8 is connected between the outlet 211 of the condenser body 21 and the input end of the evaporator 10, and the throttle 8 is connected in series with the refrigeration output pipe 22. The throttle 8, the refrigeration input pipe 23, the condenser body 21, and the refrigeration output pipe 22 are all connected in parallel with the switching valve 7, and the throttle 8, the refrigeration input pipe 23, the condenser body 21, and the refrigeration output pipe 22 are all connected in parallel with the bypass pipe 24.

[0079] Exemplarily, the switching valve 7 may be a two-way valve.

[0080] Exemplarily, the switching valve 7 may be a solenoid valve.

[0081] Exemplarily, the switching valve 7 may be a manual valve.

[0082] Exemplarily, the restrictor 8 may be a capillary tube.

[0083] Exemplarily, the restrictor 8 may be an expansion valve or a throttle valve.

[0084] In the embodiment of the present application, when the switching valve 7 is closed, since the throttle 8 is connected in series with the refrigeration output pipe 22, the throttle 8, the refrigeration input pipe 23, the condenser body 21 and the refrigeration output pipe 22 are all connected in parallel with the switching valve 7, and the throttle 8, the refrigeration input pipe 23, the condenser body 21 and the refrigeration output pipe 22 are all connected in parallel with the bypass pipe 24. The refrigerant discharged from the compressor 1 flows to the throttle 8 through the refrigeration input pipe 23, the condenser body 21 and the refrigeration output pipe 22 for throttling expansion and then enters the evaporator 10 for evaporation and heat absorption for refrigeration. The throttle 8 is connected in series with the refrigeration output pipe 22. The throttle 8, the refrigeration input pipe 23, the condenser body 21, and the refrigeration output pipe 22 are all connected in parallel with the switching valve 7. The throttle 8, the refrigeration input pipe 23, the condenser body 21, and the refrigeration output pipe 22 are all connected in parallel with the bypass pipe 24. When the switching valve 7 is open, due to the large resistance of the throttle 8, the refrigerant of the compressor 1 almost does not flow through the branch of the refrigeration input pipe 23, the condenser body 21, and the refrigeration output pipe 22. The refrigerant of the compressor 1 flows to the evaporator 10 through the bypass pipe 24 with smaller resistance to defrost. The switching of the switching valve 7 realizes the switching between the refrigeration and defrost functions.

[0085] It is understood that the structure of the refrigeration system is not limited. For example, in addition to the switching valve 7 between the third port 63 and the evaporator 10, a switching valve 7 may be connected between the refrigeration output pipe 22 and the input end of the evaporator 10, and the throttle 8 may not be provided. For example, the throttle 8 may be provided but the switching valve 7 may not be provided, and the three-way pipe 6 may be replaced with a three-way valve for switching.

[0086] In some embodiments, see Figure 1 and Figure 2 The switching valve 7 is connected in series between the bypass pipe 24 and the input end of the evaporator 10 .

[0087] For example, see Figure 1 and Figure 2 One end of the bypass pipe 24 is connected to the third port 63 , and the other end of the bypass pipe 24 has a fifth port 242 . The switching valve 7 is connected in series between the fifth port 242 and the input end of the evaporator 10 .

[0088] In an embodiment of the present application, the switching valve 7 is connected in series between the bypass pipe 24 and the evaporator 10. While meeting the basic switching requirements of the refrigeration and defrosting functions, the switching valve 7 can be as far away from the refrigeration input pipe 23 as possible, thereby reducing the interference between the switching valve 7 and the refrigeration input pipe 23.

[0089] It is understandable that the arrangement of the switching valve 7 is not limited. For example, the switching valve 7 can be connected in series to the bypass pipe 24, and the switching valve 7 is arranged on the bypass pipe 24.

[0090] In some embodiments, see Figure 1 and Figure 2 The throttle 8 is connected in series between the refrigeration output pipe 22 and the input end of the evaporator 10.

[0091] For example, see Figure 1 and Figure 2 One end of the refrigeration output pipe 22 is connected to the outlet 211 of the condenser body 21 , and the other end of the refrigeration output pipe 22 has a sixth interface 221 , and the throttle 8 is connected in series between the sixth interface 221 and the input end of the evaporator 10 .

[0092] In the embodiment of the present application, the refrigeration output pipe 22 and the condenser body 21 are fed as a whole, and the shape of the refrigeration output pipe 22 is basically fixed. The throttle 8 is connected in series between the refrigeration output pipe 22 and the input end of the evaporator 10, so that the installation of the throttle 8 is more convenient and flexible, and the corresponding components can be added or reduced upstream and downstream of the throttle 8 according to actual needs.

[0093] It is understandable that the arrangement of the throttle 8 is not limited. For example, the throttle 8 is connected in series to the refrigeration output pipe 22, and the throttle 8 is provided on the refrigeration output pipe 22.

[0094] In some embodiments, see Figure 1 and Figure 2 The refrigeration system further includes a drying filter 9, which is connected in series between the refrigeration output pipe 22 and the throttle 8.

[0095] The drying filter 9 plays the role of drying and filtering impurities. A desiccant is provided in the drying filter 9, and the refrigerant is dried by the desiccant.

[0096] In the embodiment of the present application, the filter is placed between the refrigeration output pipe 22 and the throttle 8, and the refrigerant entering the throttle 8 is dried and filtered by the drying filter 9, and the position of the drying filter 9 relative to the throttle 8 can be set more conveniently and flexibly.

[0097] It is understandable that the specific structure of the filter dryer 9 is not limited. For example, the filter dryer 9 is connected in series to the refrigeration output pipe 22, and the filter dryer 9 is arranged on the refrigeration output pipe 22.

[0098] In some embodiments, see Figure 1 and Figure 2 , the first water receiving device is located below the condenser body 21.

[0099] In an embodiment of the present application, the refrigeration input pipe 23 is connected to the inlet 212 of the condenser body 21. The refrigeration input pipe 23 and the bypass pipe 24 are both used to receive the refrigerant discharged from the compressor 1. At least part of the refrigeration input pipe 23 and the bypass pipe 24 are relatively close to the condenser body 21. This part of the pipe is not far from the condenser body 21. Since the first water receiving device is located below the condenser body 21, the first water receiving device is relatively close to the condenser body 21, so that at least part of the refrigeration input pipe 23 and the bypass pipe 24 can be more conveniently arranged in the first water receiving device.

[0100] It is understandable that the arrangement of the first water receiving device is not limited. For example, the first water receiving device can be arranged on one side of the condenser body 21 along the horizontal direction.

[0101] In some embodiments, see Figure 1 and Figure 2 The refrigeration system also includes a second water receiving device located below the evaporator 10, the second water receiving device is used to receive water during the defrosting process of the evaporator 10, and the first water receiving device is connected to the second water receiving device to receive water from the second water receiving device.

[0102] Exemplarily, the second water receiving device is a second water receiving tray.

[0103] The second water receiving device is located below the evaporator 10 and is directly used to receive the water melted by the defrosting of the evaporator 10. The water melted during the defrosting process of the evaporator 10 is first collected in the second water receiving device, thereby limiting the melted water of the evaporator 10 from scattering onto other components of the refrigeration system. The water in the second water receiving device can be discharged to the first water receiving device connected to the second water receiving device, so that the water collected in the second water receiving device is gathered to the first water receiving device and heated by the higher temperature refrigerant in the bypass pipe 24, thereby accelerating the evaporation of the water in the first water receiving device and reducing the possibility of water overflow in the first water receiving device.

[0104] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
