[0040] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0041] The following is for reference. Figures 1-8 This application describes a refrigeration cycle system and a refrigeration device according to embodiments of the present application.

[0042] It should be noted that the refrigeration equipment in the embodiments of this application can be understood as a broad refrigeration storage device, including but not limited to freezers, refrigerators, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines, etc. Refrigeration equipment has diverse structural forms and a wide range of applications.

[0043] like Figure 1 As shown, the refrigeration cycle system of the refrigeration equipment in this embodiment includes an evaporator 110, a throttling component 171, a compressor 120, and a condenser module.

[0044] The compressor 120 can compress high-temperature, high-pressure, superheated refrigerant; the throttling component 171 throttles the refrigerant condensed by the condenser module; the evaporator 110 is a heat exchanger that transfers heat from the refrigeration space to the refrigerant; and the condenser module is used to condense the refrigerant.

[0045] In this embodiment, the evaporator 110, compressor 120, condenser module and throttling component 171 are connected in sequence to form a refrigeration circuit.

[0046] Understandably, the refrigeration cycle system may also include a dryer filter 160, a return gas heat exchange component 172, etc.

[0047] The circulation process of the refrigerant in the refrigeration cycle system is that the compressor 120 inhales the refrigerant at low temperature and low pressure, compresses the refrigerant gas into high temperature and high pressure, and then discharges the condenser module. The condenser module condenses the refrigerant. The condensed refrigerant flows into the throttling assembly 171 after filtering out water and impurities through the drying filter 160. The throttling assembly 171 throttles and depressurizes the refrigerant. Then, the refrigerant starts to absorb heat and vaporize in the evaporator 110 to achieve the purpose of refrigeration. The refrigerant is heat-treated by the gas return heat exchange assembly 172 and returns to the compressor 120 for compression to realize the circulation of the refrigerant.

[0048] In this embodiment, the condenser module includes a first condenser 130 and a second condenser.

[0049] The first condenser 130 includes a shell 131 and a first condensing assembly 132. The shell 131 is used to hold liquid medium, and the first condensing assembly 132 is located in the shell 131 and immersed in the liquid medium.

[0050] It can be understood that the first condenser 130 is an immersion condenser. The refrigerant in the first condensing assembly 132 exchanges heat with the liquid medium in the shell 131, and the condensing efficiency is high. The liquid medium in the shell 131 can be water, or a water solution such as brine with water as the main carrier, or other liquids. Different types of liquid medium can be selected according to the actual refrigeration requirements of the refrigeration equipment.

[0051] In this embodiment, the shell 131 of the first condenser 130 can have a closed structure to reduce the loss of liquid medium and avoid changes in the concentration of the liquid medium.

[0052] In this embodiment, the second condenser can be a pipe condenser or a heat exchange device such as a wind-cooled condenser 140.

[0053] In this embodiment, the input end of the first condenser 130, the input end of the second condenser, and the output end of the compressor 120 are connected through a three-way diverter valve 150.

The input end of the throttling assembly 171 is connected with the output end of the first condenser 130 and the output end of the second condenser respectively.

[0055] In this embodiment, the first condenser 130 and the second condenser are connected in parallel. The three-way diverter valve 150 can control the refrigerant to flow into the first condenser 130 or the second condenser.

[0056] In actual implementation, the refrigerant path regulated by the three-way distribution valve 150 can be adjusted according to actual refrigeration requirements of the refrigeration device.

[0057] The flow direction and morphological changes of the refrigerant in the refrigeration cycle system are described below.

[0058] The high-temperature and high-pressure superheated refrigerant compressed by the compressor 120 is cooled by the first connecting pipe 210, and the high-temperature and high-pressure refrigerant is no longer superheated, and enters the first condenser 130 or the second condenser for condensation through the three-way distribution valve 150.

[0059] The condensed high-pressure and low-temperature refrigerant enters the second connecting pipe 220, and then enters the drying filter 160.

[0060] Subsequently, the refrigerant enters the throttling assembly 171 to be throttled into low-temperature and low-pressure two-phase refrigerant, enters the evaporator 110 to be refrigerated into low-pressure and low-temperature gas-phase refrigerant, and finally enters the compressor 120 through the gas return heat exchange assembly 172 to complete the cycle, and the cycle is repeated to realize the refrigeration function.

[0061] The first connecting pipe 210 is a structure that can cool and condense the refrigerant, and the second connecting pipe 220 can be arranged at an opening of a chamber formed in the inner container of the refrigeration device to prevent condensation caused by the temperature difference between the chamber and the opening.

[0062] In the related art, different fresh-keeping chambers are usually provided, and different fresh-keeping chambers are suitable for different refrigeration requirements. However, this scheme is only suitable for large refrigeration devices.

[0063] In the embodiment of the present application, the condenser module includes the first condenser 130 and the second condenser in parallel, the input end of the first condenser 130, the input end of the second condenser, and the output end of the compressor 120 are communicated through the three-way distribution valve 150, the refrigerant can be controlled to enter the first condenser 130 or the second condenser for condensation through the three-way distribution valve 150 according to actual refrigeration requirements, the first condenser 130 belongs to an immersion condenser, the condensation efficiency is high, the condensation effect is good, two condensers in parallel can adapt to more refrigeration environments, and when one condenser fails, the other condenser can be used, and the reliability of the refrigeration cycle system is high.

[0064] According to the refrigeration cycle system of the refrigeration device provided in the embodiment of the present application, the condenser module including the first condenser 130 and the second condenser is arranged, the first condenser 130 and the second condenser are in parallel, the refrigerant can be controlled to enter the first condenser 130 or the second condenser for condensation according to actual refrigeration requirements, the first condenser 130 belongs to an immersion condenser, the condensation efficiency is high, two condensers in parallel can adapt to more refrigeration environments, and the reliability of the refrigeration cycle system is high.

[0065] In some embodiments, the second condenser comprises a second condensing component 141, and the refrigerant flows through the second condensing component 141 and exchanges heat with air outside the second condensing component 141.

[0066] It can be understood that the second condenser can belong to a tube type condenser, and the refrigerant in the second condensing component 141 exchanges heat with air.

[0067] The second condensing component 141 can be a component with smooth surface, and the second condenser can belong to a light tube type condenser 180.

[0068] Hereinafter, taking the second condenser as the light tube type condenser 180 as an example, the flow direction of the refrigerant in the refrigeration cycle system, the change of the refrigerant, and the like are described.

[0069] As shown in FIG. 1, the high-temperature and high-pressure superheated refrigerant compressed by the compressor 120 is cooled by the first connecting pipe 210, and the high-temperature and high-pressure refrigerant is no longer superheated, and enters the first condenser 130 or the light tube type condenser 180 to be condensed through the three-way diverging valve 150. Figure 2

[0070] The condensed high-pressure and low-temperature refrigerant enters the second connecting pipe 220, and then enters the drying filter 160.

[0071] Subsequently, the refrigerant enters the throttling component 171 to be throttled into low-temperature and low-pressure two-phase refrigerant, enters the evaporator 110 to be refrigerated into low-pressure and low-temperature gas-phase refrigerant, and finally enters the compressor 120 through the return gas heat exchange component 172 to complete the cycle, and the cycle is repeated to realize the refrigeration function.

[0072] In some embodiments, the second condenser further comprises a fan 142, and the fan 142 is used to accelerate the flow of air outside the second condensing component 141.

[0073] It can be understood that the second condenser can belong to the air-cooled condenser 140, and the air-cooled condenser 140 is a forced convection cooling type heat exchange device, and components such as the fan 142 are configured to strengthen the convection.

[0074] In this embodiment, the refrigerant in the second condensing component 141 exchanges heat with air, and the air can be natural convection or forced flow of the air-cooled condenser 140. Whether the fan 142 needs to be turned on to realize forced convection heat exchange can be determined according to the refrigeration demand.

[0075] Hereinafter, taking the second condenser as the air-cooled condenser 140 as an example, the flow direction of the refrigerant in the refrigeration cycle system, the change of the refrigerant, and the like are described.

[0076] As shown in FIG. 2, the high-temperature and high-pressure superheated refrigerant compressed by the compressor 120 is cooled by the first connecting pipe 210, and the high-temperature and high-pressure refrigerant is no longer superheated, and enters the air-cooled condenser 140 to be condensed through the three-way diverging valve 150. Figure 1 ​As shown, the high-temperature and high-pressure superheated refrigerant compressed by the compressor 120 is cooled by the first connecting pipe 210, and the high-temperature and high-pressure refrigerant is no longer superheated, and enters the first condenser 130 or the air-cooled condenser 140 to be condensed through the three-way distribution valve 150.

[0077] The condensed high-pressure and low-temperature refrigerant enters the second connecting pipe 220, and then enters the drying filter 160.

[0078] Subsequently, the refrigerant enters the throttling assembly 171 to be throttled into low-temperature and low-pressure two-phase refrigerant, enters the evaporator 110 to be refrigerated into low-pressure and low-temperature gas-phase refrigerant, and finally enters the compressor 120 through the gas return heat exchange assembly 172 to complete the cycle, and the cycle is repeated to realize the refrigeration function.

[0079] In some embodiments, the second condensing assembly 141 is a tube type condensing assembly or a fin type condensing assembly.

[0080] The second condensing assembly 141 of the second condenser can be a heat exchange assembly of a tube type condensing assembly or a fin type condensing assembly, and the air flow flows onto the tube type or fin type second condensing assembly 141 to exchange heat, and the heat exchange efficiency is high and the condensing effect is good.

[0081] In some embodiments, the first condensing assembly 132 is a tube type condensing assembly or a fin type condensing assembly.

[0082] The first condensing assembly 132 of the first condenser 130 is immersed in a liquid medium, and the first condensing assembly 132 can be a heat exchange assembly of a tube type condensing assembly or a fin type condensing assembly, and the heat exchange efficiency of the tube type or fin type first condensing assembly 132 with the liquid medium is high and the condensing effect is good.

[0083] In actual execution, when the first condensing assembly 132 and the second condensing assembly 141 are integrated structures, the first condensing assembly 132 and the second condensing assembly 141 can be the same type of heat exchange structure, or different types of heat exchange structure.

[0084] In some embodiments, as shown, Figure 1 As shown, the refrigeration cycle system of the refrigeration equipment further includes a first connecting pipe 210.

[0085] The input end of the first connecting pipe 210 is communicated with the output end of the compressor 120, the output end of the first connecting pipe 210 is communicated with the input end of the condenser module, and the first connecting pipe 210 is used for condensing the refrigerant output by the compressor 120.

[0086] It can be understood that the first connecting pipe 210 can be a pre-cooling pipe, and the high-temperature and high-pressure superheated refrigerant compressed by the compressor 120 can be preliminarily condensed through the pre-cooling pipe, and the high-temperature and high-pressure superheated refrigerant becomes high-temperature and high-pressure refrigerant and is no longer superheated.

[0087] In some embodiments, as shown in Figure 1 The refrigeration cycle system of the refrigeration equipment further comprises a second connecting pipe 220.

[0088] The input end of the second connecting pipe 220 is communicated with the output end of the condenser module, and the output end of the second connecting pipe 220 is communicated with the input end of the throttling assembly 171. The second connecting pipe 220 is used to release heat and prevent frost.

[0089] It can be understood that the first connecting pipe 210 can be a dew prevention pipe, which can be arranged at an opening of a chamber formed by the inner container of the refrigeration equipment to prevent condensation caused by temperature difference between the chamber and the opening and prevent frost.

[0090] In some embodiments, as shown in Figure 1 The refrigeration cycle system of the refrigeration equipment further comprises a gas return heat exchange assembly 172.

[0091] The input end of the gas return heat exchange assembly 172 is communicated with the output end of the evaporator 110, and the output end of the gas return heat exchange assembly 172 is communicated with the input end of the compressor 120.

[0092] In this embodiment, the first connecting pipe 210 can be an assembly that can exchange heat with the gas return heat exchange assembly 172.

[0093] Among the first connecting pipe 210, the gas return heat exchange assembly 172 and the condenser module, the temperature of the first connecting pipe 210 is the highest, and the refrigerant after evaporative refrigeration and the refrigerant after compression and temperature rise exchange heat. The refrigeration system is suitable for operation in a conventional refrigeration temperature range of 4°C to -20°C.

[0094] For example, as shown in Figure 3 The high-temperature and high-pressure superheated refrigerant compressed by the compressor 120 is preliminarily condensed through the first connecting pipe 210, the high-temperature and high-pressure superheated refrigerant becomes high-temperature and high-pressure refrigerant, and is no longer superheated. The high-temperature and high-pressure refrigerant enters the first condenser 130 or the second condenser.

[0095] After the high-pressure and low-temperature refrigerant enters the second connecting pipe 220, it enters the dry filter 160, then enters the throttling assembly 171 to become low-temperature and low-pressure two-phase refrigerant, enters the evaporator 110 to be refrigerated to become low-pressure and low-temperature gas-phase refrigerant, and finally returns to the compressor 120 through the gas return heat exchange assembly 172 to complete the cycle.

[0096] The throttling assembly 171 can be an expansion valve.

[0097] In this embodiment, the refrigeration cycle system of the refrigeration equipment can comprise two gas return heat exchange assemblies 172.

[0098] AsFigure 4 As shown, the input end of the first return gas heat exchange component 172 is connected to the output end of the dryer filter 160, the output end of the first return gas heat exchange component 172 is connected to the input end of the throttling component 171, the output end of the throttling component 171 is connected to the input end of the evaporator 110, the output end of the evaporator 110 is connected to the input end of the second return gas heat exchange component 172, the output end of the second return gas heat exchange component 172 is connected to the input end of the compressor 120, and the output end of the compressor 120 is connected to the input end of the condenser module through the first connecting pipe 210.

[0099] In this embodiment, the refrigerant is first reheated by the first return gas heat exchange component 172, then throttled by the throttling component 171, then evaporated and cooled by the evaporator 110, and then reheated a second time by the second return gas heat exchange component 172 before being input into the compressor 120 for compression.

[0100] The first return gas heat exchange component 172 exchanges heat with the second return gas heat exchange component 172. The first return gas heat exchange component 172 contains the refrigerant condensed by the condenser module, and the second return gas heat exchange component 172 contains the refrigerant cooled by the evaporator 110. The refrigerant temperature of the first return gas heat exchange component 172 is higher than that of the second return gas heat exchange component 172.

[0101] The throttling component 171 can be an expansion valve.

[0102] In this embodiment, the positions of the first return gas heat exchange component 172 and the dryer filter 160 can be interchanged, that is, the input end of the dryer filter 160 can be connected to the output end of the first return gas heat exchange component 172.

[0103] like Figure 5 As shown, the output end of the first return gas heat exchange component 172 is connected to the input end of the throttling component 171 through the dryer filter 160. The refrigerant first passes through the first return gas heat exchange component 172 for reheating, then passes through the throttling component 171 for throttling, then passes through the evaporator 110 for evaporation and cooling, and then passes through the second return gas heat exchange component 172 for a second reheating before being input into the compressor 120 for compression.

[0104] The throttling component 171 can be an expansion valve.

[0105] In some embodiments, the throttling component 171 is a capillary tube, which exchanges heat with the return gas heat exchange component 172, and the refrigerant temperature of the capillary tube is greater than the refrigerant temperature of the return gas heat exchange component 172.

[0106] like Figure 1As shown, the condensed refrigerant of the condenser module enters the drying filter 160, and after drying and filtering, the refrigerant enters the throttling assembly 171 which is a capillary tube to be throttled into low-temperature and low-pressure two-phase refrigerant, enters the evaporator 110 to be refrigerated into low-pressure and low-temperature gaseous refrigerant, and finally enters the compressor 120 through the gas return heat exchange assembly 172 to complete the cycle.

[0107] The capillary tube exchanges heat with the gas return heat exchange assembly 172, the refrigerant in the capillary tube is the condensed refrigerant of the condensing heat rejection module, and the refrigerant in the gas return heat exchange assembly 172 is the refrigerant after being refrigerated by the evaporator 110, and the temperature of the refrigerant in the capillary tube is higher than that of the refrigerant in the gas return heat exchange assembly 172.

[0108] It can be understood that after the heat exchange between the capillary tube and the gas return heat exchange assembly 172, the temperature of the refrigerant in the capillary tube is reduced, and the temperature of the refrigerant in the gas return heat exchange assembly 172 is increased.

[0109] The application also provides a refrigeration equipment.

[0110] The refrigeration equipment comprises the refrigeration cycle system described above.

[0111] According to the refrigeration equipment provided by the application, the condenser module comprising the first condenser 130 and the second condenser is arranged, the first condenser 130 and the second condenser are connected in parallel, the refrigerant can be controlled to be input to the first condenser 130 or the second condenser for condensation according to actual refrigeration requirements, the first condenser 130 belongs to an immersion condenser, the condensation efficiency is high, two condensers connected in parallel can adapt to more refrigeration environments, and the reliability of the refrigeration cycle system is high.

[0112] In this embodiment, as shown in the figure, Figure 6 The refrigeration equipment comprises a shell 600 and an inner container, the inner container is installed in the shell 600 to form a storage compartment, and the shell 600 further forms a compressor compartment 610 for placing components such as the compressor 120, the first condenser 130 and the second condenser.

[0113] The compressor compartment 610 can be located at the bottom of the shell 600 of the refrigeration equipment, and the bottom of the compressor compartment 610 can be provided with a bottom plate for installing components such as the compressor 120, the first condenser 130 and the second condenser.

[0114] In this embodiment, when the second condenser is the air-cooled condenser 140, the compressor 120 is located at the downwind position of the air-cooled condenser 140, and the first condenser 130 is not located at the downwind position of the air-cooled condenser 140, but can be located at the upwind position of the air-cooled condenser 140.

[0115] Taking the refrigeration equipment as a horizontal refrigerator as an example, the arrangement of components in the compressor chamber 610 when the second condenser is a air-cooled condenser 140 is described.

[0116] As shown in FIG. 13, the compressor chamber 610 is arranged in sequence from left to right as the compressor 120, the fan 142, the second condensing assembly 141 and the first condenser 130, the compressor 120 is located at the downwind position of the air-cooled condenser 140, and the first condenser 130 is located at the upwind position of the air-cooled condenser 140. Figure 6

[0117] When the fan 142 works to suck air, the air flow first passes through the shell 131 of the first condenser 130 for heat exchange, and the temperature of the air flow does not change greatly; then the air flow passes through the second condensing assembly 141 for heat exchange, the temperature of the refrigerant in the second condensing assembly 141 is reduced, and the temperature of the air flow passing through the second condensing assembly 141 is increased; finally, the air flow blows on the compressor 120 for heat exchange, thereby improving the compression efficiency of the compressor 120.

[0118] In some embodiments, the compressor chamber 610 is further provided with a first water collecting box 710, the first water collecting box 710 is arranged at the bottom of the compressor chamber 610 and below the shell 131, and an end of the first water collecting box 710 close to the shell 131 is open.

[0119] In this embodiment, as shown in FIG. 13, the first water collecting box 710 is arranged at the bottom of the compressor chamber 610 and below the shell 131, and when the shell 131 of the first condenser 130 is damaged, the first water collecting box 710 can collect the liquid medium leaked from the first condenser 130, thereby preventing the liquid from flowing to the bottom of the compressor chamber 610 or out of the refrigeration equipment. Figure 7 In actual execution, when the refrigeration equipment is an air-cooled product, the first water collecting box 710 can also collect defrosting water when the refrigeration equipment performs defrosting operation.

[0120] It can be understood that the first water collecting box 710 is arranged at the bottom of the compressor chamber 610, the bottom surface of the first water collecting box 710 is in contact with the bottom of the compressor chamber 610 for heat conduction, and the open end of the first water collecting box 710 can also realize evaporation of the liquid in addition to collecting the liquid.

[0121] In some embodiments, as shown in FIG. 13, the projection area of the first water collecting box 710 on the bottom of the compressor chamber 610 is greater than the projection area of the shell 131 on the bottom of the compressor chamber 610.
