DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0037] The terms "first", "second", etc. in the specification and claims of the present disclosure are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects related to each other are in an "or" relationship.

[0038] The refrigeration system, control method, control device, refrigeration device and storage medium provided by the embodiments of the present disclosure are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0039] Refrigeration equipment such as refrigerators, cold storages, refrigerated trucks, air conditioners, etc. usually includes a box body and a refrigeration system arranged on the box body, and the box body is provided with multiple compartments.

[0040] Each compartment of the refrigeration equipment is also provided with a door body for opening and closing the above compartment. A seal is provided on the door body of each compartment to increase the sealing of each compartment and prevent the cold from leaking out. When the compartment is opened, the cold inside the compartment diffuses to the outside through the seal of the door body, creating a temperature difference with the external environment of the compartment. Therefore, condensation is more likely to occur at the joint between the compartment and the door body.

[0041] At present, an integrated anti-condensation pipe is set near the seal of each compartment door to release heat when the compartment is opened, reduce the temperature difference between the compartment and the external environment, and prevent condensation.

[0042] However, under normal circumstances, the cooling temperature of each compartment is different, so the temperature difference between each compartment and the external environment is different. When the relative humidity of the environment in each compartment is the same, the lower the cooling temperature of the compartment, the greater the temperature difference between it and the external environment, and the easier it is to produce condensation. When condensation occurs in a compartment with a lower cooling temperature, the compartment with a higher cooling temperature may not produce condensation. At this time, the heat released by the integrated anti-condensation pipe is used to prevent condensation in the compartment with a lower cooling temperature, which will release excess heat in the compartment with a higher cooling temperature. In order to maintain the cooling temperature of the compartment, the refrigeration equipment will consume more energy.

[0043] As shown in Figure 1, an embodiment of the present disclosure provides a refrigeration system, which includes a main circulation loop, multiple circulation branches and a switching valve 130. The main circulation loop includes a compressor 110 and a condenser 120 connected in sequence. The multiple circulation branches are arranged in parallel. Each circulation branch is provided with an anti-dew pipe (141, 143). At least one circulation branch is provided with an evaporator. The switching valve 130 has an inlet and multiple outlets. The inlet of the switching valve 130 is connected to the outlet of the condenser 120, and the inlet of the anti-dew pipe (141, 143) is connected to the outlet of the switching valve 130.

[0044] The refrigeration system is arranged on the housing of the refrigeration equipment. The refrigeration system is also provided with a controller, which is respectively connected to the compressor 110, the condenser 120, and the switching valve 130 to control the switching and operating parameters of these components.

[0045] Different circulation branches can be set in different compartments of the refrigeration equipment. The conditions for condensation in different compartments are different. The controller controls the anti-condensation component 130 to open one or more anti-condensation pipes under different conditions. The controller controls the switching valve to open the corresponding outlet according to the anti-condensation requirements of each position, so that the corresponding anti-condensation pipe is prevented from condensing. This can prevent the generation of excess heat during anti-condensation and avoid increased energy consumption of the equipment.

[0046] The exhaust port of compressor 110 is connected to the input port of condenser 120, and the output port of condenser 120 is connected to the inlet port of switching valve 130. Compressor 110 compresses the heat exchange medium into a high-temperature, high-pressure gas by performing work. Condenser 120 removes the heat from the gaseous heat exchange medium of compressor 110, cooling the heat exchange medium into a high-pressure, room-temperature liquid. The liquid heat exchange medium is discharged from the output port of condenser 120 and enters the inlet port of switching valve 130. Switching valve 130 is provided with multiple outlet ports. By controlling switching valve 130 to connect the inlet port and at least one outlet port, the heat exchange medium can be transferred to the anti-condensation pipe.

[0047] The heat exchange medium may be Freon, saturated hydrocarbons or unsaturated hydrocarbons, etc.

[0048] Each circulation branch is also equipped with a throttling element. At least one circulation branch is equipped with an evaporator. The first end of the throttling element is connected to the outlet of the anti-condensation pipe of the branch in which it is located. In the circulation branch equipped with an evaporator, the second end of the throttling element is connected to the first end of the evaporator in the branch in which it is located. In the circulation branch without an evaporator, the second end of the throttling element is connected to the first end of the evaporator in the main circulation loop. The heat exchange medium passing through the anti-condensation pipe of each circulation branch flows through the corresponding throttling element. The throttling element limits the flow of the high-pressure, normal-temperature heat exchange medium and reduces its pressure to a low-temperature, low-pressure liquid. The low-temperature, low-pressure heat exchange medium continuously absorbs heat in each evaporator and gradually vaporizes, removing heat from the surrounding environment and achieving a cooling effect.

[0049] Each circulation branch is correspondingly arranged near the seal of each compartment door body, so that when the compartment is opened, the anti-condensation pipe releases heat, reduces the temperature difference between the compartment and the external environment, and prevents condensation.

[0050] It should be noted that since each circulation branch is independently cooled and does not affect each other, different anti-condensation pipes require different anti-condensation conditions. A single-inlet, multi-outlet switching valve 130 is used. By controlling the switching valve 130 to connect the inlet and different outlets, the heat exchange medium is transferred to different anti-condensation pipes. The heat exchange medium flows through the connected anti-condensation pipes, raising the temperature around the anti-condensation pipes. The anti-condensation pipes prevent condensation by releasing the heat of the heat exchange medium.

[0051] According to the refrigeration system disclosed in the present invention, a plurality of circulation branches are provided, each of which is provided with an anti-dew pipe, and each anti-dew pipe can be independently protected from dew. In the equipment, each circulation branch can be arranged at a different position, and the switching valve 130 is connected to the corresponding outlet according to the anti-dew requirements of each position, so that the corresponding anti-dew pipe can be protected from dew, thereby preventing the generation of excess heat during anti-dew and avoiding increased energy consumption of the equipment.

[0052] In some embodiments, at least one circulation branch is provided with a bypass pipe, the input end of the bypass pipe is connected to the outlet of the switching valve 130 and is connected in parallel with the anti-dew pipe.

[0053] When the anti-condensation pipes in the circulation branch are not conductive, that is, anti-condensation is not required in the refrigeration system, the heat exchange medium discharged from the condenser 120 flows through the bypass pipe directly into the throttling element, participating in the refrigeration work, thereby realizing full utilization of the heat exchange medium.

[0054] In some embodiments, each anti-condensation pipe is provided with a bypass pipe, so that when anti-condensation is not needed, the bypass pipe can be controlled to be open and the anti-condensation pipe can be closed, thereby avoiding the problem of the anti-condensation pipe of the freezer and / or refrigerator compartment being continuously open, causing the heat load of the compartment to increase.

[0055] Taking a refrigerator as an example, the cabinet typically features a freezer and refrigerator compartments. The cabinet is equipped with the aforementioned refrigeration system, and each compartment has corresponding circulation branches. The freezer compartment's temperature is lower than the refrigerator compartment's, and the temperature difference between the freezer compartment and the refrigerator's external environment is greater than the temperature difference between the refrigerator compartment and the refrigerator's external environment. This creates different risks of condensation in the freezer and refrigerator compartments. The anti-condensation pipe releases heat to reduce the temperature difference between the freezer and refrigerator compartments and the external environment, preventing condensation. The basic structure and principles of refrigerators are well-established in the prior art and will not be elaborated on here.

[0056] In some embodiments, the refrigeration system includes two circulation branches, the first circulation branch includes a first anti-dew pipe 141 and a first bypass pipe 142, and the second circulation branch includes a second anti-dew pipe 143 and a second bypass pipe 144. The outlets of the switching valve 130 are respectively connected to the inlet of the first anti-dew pipe 141, the inlet of the first bypass pipe 142, the inlet of the first anti-dew pipe 143 and the inlet of the second bypass pipe 144, the outlet of the first anti-dew pipe 141 is connected to the outlet of the first bypass pipe 142, and the outlet of the first anti-dew pipe 143 is connected to the outlet of the second bypass pipe 144.

[0057] In some embodiments, a one-inlet, four-outlet switching valve is used. The first outlet 131 of the switching valve 130 is connected to the inlet of the first anti-condensation pipe 141, the second outlet 132 of the switching valve 130 is connected to the inlet of the first bypass pipe 142, the third outlet 133 of the switching valve 130 is connected to the inlet of the second anti-condensation pipe 143, and the fourth outlet 134 of the switching valve 130 is connected to the inlet of the second bypass pipe 144.

[0058] When the switching valve 130 connects the inlet and the first outlet 131, the heat exchange medium flows through the first anti-condensation pipe 141, and the first anti-condensation pipe 141 is used to prevent condensation; when the switching valve 130 connects the inlet and the second outlet 132, the heat exchange medium flows through the first bypass pipe 142, and the first circulation branch is not protected from condensation; when the switching valve 130 connects the inlet and the third outlet 133, the heat exchange medium flows through the third anti-condensation pipe, and the first anti-condensation pipe 143 is used to prevent condensation; when the switching valve 130 connects the inlet and the fourth outlet 134, the heat exchange medium flows through the second bypass pipe 144, and the second circulation branch is not protected from condensation.

[0059] By controlling the conduction between the inlet and different outlets of the switching valve, the anti-dew pipes in each cycle braking can be switched to perform anti-dew action, thereby realizing flexible control of the anti-dew function.

[0060] As an example, the second circulation branch is provided with a second throttling element 152, the first circulation branch is provided with a first throttling element 151 and a first evaporator 161, and the main circulation branch is provided with a second evaporator 162. The input end of the first throttling element 151 is respectively connected to the output ends of the first anti-dew pipe 141 and the first bypass pipe 142, the output end of the first throttling element 151 is connected to the input end of the first evaporator 161, the input end of the second throttling element 152 is respectively connected to the output ends of the first anti-dew pipe 143 and the second bypass pipe 144, the output end of the second throttling element 152 is respectively connected to the output end of the first evaporator 161 and the input end of the second evaporator 162, and the output end of the second evaporator 162 is connected to the intake end of the compressor 110.

[0061] As shown in FIG2 , an embodiment of the present disclosure provides a control method for controlling the refrigeration system. In this embodiment, the control method includes steps 10 and 20 .

[0062] Step 10: Obtain the relative humidity of the environment in which the refrigeration system is located;

[0063] Step 20: When a cooling request of a circulation branch in the refrigeration system is detected and the relative humidity is greater than or equal to a reference humidity corresponding to the circulation branch, the anti-dew pipe corresponding to the circulation branch is controlled to be conductive.

[0064] An embodiment of the present disclosure provides a control method, and the execution subject of the control method can be the controller of the aforementioned refrigeration system or a functional module or functional entity in the controller that can implement the control method. The control method provided by the embodiment of the present disclosure is explained below using the controller as an example of the execution subject.

[0065] Relative humidity is the ratio of the actual water vapor pressure in the air to the saturated water vapor pressure at the prevailing temperature. It reflects the mass of water vapor in moist air compared to the mass of water vapor in saturated air at the same temperature and pressure. The refrigeration system environment refers to the humidity outside the refrigeration equipment compartments when the doors are closed.

[0066] It is understandable that the compartments of the refrigeration equipment are in the same space, and the relative humidity outside the doors of the compartments is basically the same. Therefore, it is generally believed that the relative humidity of the environment in which the compartments of the same refrigeration equipment are located is the same at the same time.

[0067] In some embodiments, the refrigeration device may be provided with a humidity sensor, which is connected to the controller and configured to detect the relative humidity of the environment in which the refrigeration system is located and transmit the detected result to the controller. The controller may obtain the relative humidity measured by the humidity sensor.

[0068] The refrigeration system can be equipped with temperature sensors to detect the actual temperature in the compartments and transmit the detection results to the controller. The controller stores the reference temperature of each compartment when it is in cooling mode. When the actual temperature of one or more compartments is greater than the reference temperature, the controller generates a corresponding cooling request.

[0069] After the controller generates a corresponding cooling request, the refrigeration system starts to operate and the heat exchange medium circulates in each component. Therefore, the anti-condensation conditions are usually judged after confirming that each compartment has generated a cooling request.

[0070] The reference humidity for each circulation branch can be determined experimentally. Under a constant cooling temperature, the ambient humidity at which condensation begins to form is the reference humidity. Typically, different compartments have different cooling temperatures, so the reference temperature for each compartment will also be different. Of course, the reference humidity for each compartment may also be related to the region and season where the refrigeration equipment is located, so it needs to be set according to the specific situation in actual use.

[0071] Each circulation branch is set in a different compartment. When the controller detects a cooling request for one or more compartments and the relative humidity of the corresponding compartment is greater than or equal to the reference humidity corresponding to the circulation branch, it controls the anti-dew pipe corresponding to the circulation branch to be turned on to prevent dew.

[0072] According to the control method disclosed in the present invention, the refrigeration system is provided with multiple circulation branches, each circulation branch is provided with an anti-dew pipe, and each anti-dew pipe can be independently anti-dewed. In the equipment, each circulation branch can be arranged at a different position. The controller controls the switching valve 130 to open the corresponding outlet according to the anti-dew requirements of each position, so that the corresponding anti-dew pipe is anti-dewed, thereby preventing the generation of excess heat during anti-dew and avoiding increased energy consumption of the equipment.

[0073] For example, a refrigerator has a first circulation branch for the refrigerator compartment and a second circulation branch for the freezer compartment. The controller stores a first reference value RH1 for the refrigerator compartment and a second reference value RH2 for the freezer compartment. When a cooling request is received for each compartment, the controller compares the relative humidity with the first and second reference values ​​RH1 and RH2, respectively.

[0074] When there is a cooling request for the refrigerated chamber corresponding to the first circulation branch and the relative humidity is greater than or equal to the first reference humidity RH1, the refrigerated chamber needs to be anti-dew, and the controller drives the switching valve 130 to connect the inlet and the first outlet 131, so that the first anti-dew pipe 141 corresponding to the refrigerated chamber is connected.

[0075] When there is a cooling request for the freezer compartment corresponding to the second circulation branch and the relative humidity is greater than or equal to the second reference humidity RH2, the freezer compartment needs to be anti-dew, and the controller drives the switching valve 130 to connect the inlet and the third outlet 133, so that the second anti-dew pipe 143 corresponding to the freezer compartment is connected.

[0076] In some embodiments, a bypass pipe is connected in parallel to the anti-dew pipe corresponding to the circulation branch, and the control method further includes: when a cooling request of the circulation branch in the refrigeration system is detected and the relative humidity is lower than the reference humidity corresponding to the circulation branch, controlling the bypass pipe corresponding to the circulation branch to be turned on.

[0077] When there is a cooling request for the refrigerated chamber corresponding to the first circulation branch and the relative humidity is lower than the first reference humidity RH1, the refrigerated chamber does not need to be protected from dew. The controller drives the switching valve 130 to connect the inlet and the second outlet 132, so that the first bypass pipe 142 corresponding to the refrigerated chamber is connected.

[0078] When there is a cooling request for the freezer compartment corresponding to the second circulation branch and the relative humidity is lower than the second reference humidity RH2, the freezer compartment does not need to be protected from dew. The controller drives the switching valve 130 to connect the inlet and the fourth outlet 134, so that the second bypass pipe 144 corresponding to the freezer compartment is connected.

[0079] When the relative humidity of the environment does not meet the anti-dew condition, the anti-dew pipe is controlled to be closed and the corresponding bypass pipe is opened, so that the heat exchange medium continues to participate in the cooling work and avoids generating excess heat.

[0080] In some embodiments, the control method further includes: obtaining operating parameters of the circulation branch; and controlling the circulation branch to close when the operating parameters meet the shutdown condition.

[0081] The operating parameters of the circulation branches may be the actual temperatures in the compartments corresponding to the circulation branches, which may be measured by temperature sensors provided in the refrigeration system.

[0082] The controller pre-stores the refrigeration shutdown reference temperature T1 and the freezing shutdown reference temperature T2. When the actual temperature of the refrigeration chamber is greater than or equal to the refrigeration shutdown reference temperature T1, the controller controls the first circulation branch to close; when the actual temperature of the freezer chamber is greater than or equal to the freezing shutdown reference temperature T2, the controller controls the second circulation branch to close.

[0083] When the temperature value in the compartment reaches the shutdown reference temperature of each compartment, it means that the condensation risk has been eliminated and the control circulation branch is closed, which can avoid the anti-condensation pipe from generating excess heat and reduce energy consumption.

[0084] In some embodiments, different circulation branches correspond to different reference humidities.

[0085] Typically, the freezer compartment is cooler than the refrigerator compartment, and the temperature difference between the freezer compartment and the refrigerator's exterior is greater than the temperature difference between the freezer compartment and the refrigerator's exterior. Condensation is more likely to form in the refrigerator compartment in high-humidity environments, and in the freezer compartment in low- to medium-humidity environments. Therefore, the second anti-condensation pipe 143 needs to be open in low- to medium-humidity environments, while the first anti-condensation pipe 141 only needs to be open in high-humidity environments. Therefore, the first reference temperature of the circulation branch in the refrigerator compartment is greater than the second reference temperature of the circulation branch in the freezer compartment.

[0086] As shown in FIG3 , taking the refrigeration system shown in FIG1 as an example, an example of the process of executing anti-condensation is as follows:

[0087] After the refrigerator is powered on and starts running, the temperature sensor and humidity sensor respectively detect the temperature of each compartment of the refrigerator and the relative humidity of the external environment, and transmit the detected results to the controller.

[0088] The controller first determines whether a cooling request is being made for the refrigerator compartment. If so, it then determines the relative humidity of the environment relative to a first reference humidity RH1. If the relative humidity is greater than or equal to the first reference humidity RH1, the controller controls switching valve 130 to connect the inlet and first outlet 131. If the relative humidity is less than the first reference humidity RH1, the controller controls switching valve 130 to connect the inlet and second outlet 132.

[0089] If there is no cooling request for the refrigerator compartment, a cooling request for the freezer compartment is determined. If there is a cooling request for the freezer compartment, the relative humidity of the environment is determined relative to a second reference humidity RH2. If the relative humidity is greater than or equal to the second reference humidity RH2, the controller controls switching valve 130 to connect the inlet and third outlet 133. If the relative humidity is less than the second reference humidity RH2, the controller controls switching valve 130 to connect the inlet and fourth outlet 134.

[0090] If there is no cooling request for the freezer compartment, the controller continues to control the temperature sensor and the humidity sensor to perform measurements and re-judge.

[0091] Embodiments of the present disclosure provide a control device for controlling the aforementioned refrigeration system. The control device comprises an acquisition module and a drive module. The acquisition module is configured to obtain the relative humidity of the environment in which the refrigeration system resides; the drive module is configured to control the anti-dew pipe corresponding to the circulation branch to be conductive when a cooling request is detected in a circulation branch of the refrigeration system and the relative humidity is greater than or equal to the reference humidity corresponding to the circulation branch.

[0092] In some embodiments, the acquisition module acquires the relative humidity of the environment in which the refrigeration system is located; when the driving module detects a refrigeration request of a circulation branch in the refrigeration system and the relative humidity is greater than or equal to the reference humidity corresponding to the circulation branch, the driving module controls the anti-dew pipe corresponding to the circulation branch to be turned on.

[0093] In some embodiments, when the driving module detects a cooling request of a circulation branch in the refrigeration system and the relative humidity is lower than a reference humidity corresponding to the circulation branch, the driving module controls the bypass pipe corresponding to the circulation branch to be opened.

[0094] In some embodiments, the acquisition module may further acquire operating parameters of the circulation branch, and the driving module controls the circulation branch to be closed when the operating parameters meet the shutdown condition.

[0095] According to the control device disclosed in the present invention, the refrigeration system is provided with multiple circulation branches, each circulation branch is provided with an anti-dew pipe, and each anti-dew pipe can be independently anti-dewed. In the equipment, each circulation branch can be arranged at a different position.
