Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0034] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0035] The following description, in conjunction with the accompanying drawings, details the refrigeration system, control method, control device, refrigeration equipment, and storage medium provided in the embodiments of this application through specific examples and application scenarios.

[0036] Refrigeration equipment such as refrigerators, cold storage, refrigerated trucks, and air conditioners typically includes a housing and a refrigeration system installed on the housing, with the housing having multiple compartments.

[0037] Each compartment of the refrigeration unit is also equipped with a door for opening and closing. Each compartment door has a seal to increase airtightness and prevent cold air leakage. When a compartment is opened, the cold air inside diffuses out through the door seal, creating a temperature difference with the external environment. Therefore, condensation is more likely to occur at the joint between the compartment and the door.

[0038] Currently, integrated anti-condensation pipes are installed near the seals of each compartment door to release heat when the compartment is opened, reducing the temperature difference between the compartment and the outside environment and preventing condensation.

[0039] However, under normal circumstances, the cooling temperatures of each compartment differ, resulting in varying temperature differences between each compartment and the external environment. When the relative humidity of the environment in each compartment is the same, the lower the cooling temperature of a compartment, the greater the temperature difference between it and the external environment, and the more easily condensation occurs. When condensation occurs in a compartment with a lower cooling temperature, condensation may not occur in a compartment with a higher cooling temperature. In this case, using the heat released by the integrated anti-condensation pipe to prevent condensation in the lower-temperature compartment will release excess heat in the higher-temperature compartment, causing the refrigeration equipment to consume more energy to maintain the cooling temperature of the compartments.

[0040] like Figure 1 As shown, an embodiment of this application 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-condensation pipe (141, 143), and 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-condensation pipe (141, 143) is connected to the outlet of the switching valve 130.

[0041] The refrigeration system is installed on the casing of the aforementioned refrigeration equipment. The refrigeration system is also equipped with a controller, which is connected to the compressor 110, condenser 120, and switching valve 130 respectively to control the switching and operating parameters of these components.

[0042] Different circulation branches can be set in different compartments of the refrigeration equipment. The conditions for condensation in different compartments are different. Under different conditions, the controller controls the anti-condensation component 130 to conduct one or more anti-condensation pipes. The controller controls the switching valve to conduct the corresponding outlet according to the anti-condensation requirements of each location, so that the corresponding anti-condensation pipe can prevent condensation. This can prevent the generation of excess heat during anti-condensation and avoid increasing the energy consumption of the equipment.

[0043] The discharge end of compressor 110 is connected to the input end of condenser 120, and the output end of condenser 120 is connected to the inlet 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 from compressor 110, cooling the heat exchange medium into a high-pressure, room-temperature liquid. The liquid heat exchange medium is discharged from the output end of condenser 120 and enters the inlet of switching valve 130. Switching valve 130 has multiple outlets. By controlling the switching valve 130 to open the inlet and at least one outlet, the heat exchange medium can be transferred to the anti-condensation pipe.

[0044] The heat exchange medium can be Freon, saturated hydrocarbons, or unsaturated hydrocarbons, etc.

[0045] Each circulation branch is also equipped with a throttling element, and at least one circulation branch has an evaporator. The first end of the throttling element is connected to the outlet of the anti-condensation pipe of its respective branch. In circulation branches with evaporators, the second end of the throttling element is connected to the first end of the evaporator in that branch. In circulation branches without evaporators, 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, which limits the flow and reduces the pressure of the high-pressure, room-temperature heat exchange medium into a low-temperature, low-pressure liquid. The low-temperature, low-pressure heat exchange medium continuously absorbs heat in each evaporator, gradually vaporizes, and carries away heat from the surrounding environment, achieving a cooling effect.

[0046] Each circulation branch is located near the seal of each compartment door so that heat is released by the anti-condensation pipe when the compartment is opened, reducing the temperature difference between the compartment and the outside environment and preventing condensation.

[0047] It should be noted that since each circulation branch cools independently and does not affect the others, different anti-condensation pipes require different anti-condensation conditions. A one-inlet, multiple-outlet switching valve 130 is used. By controlling the switching valve 130 to open the inlet and different outlets, the heat exchange medium is transferred to different anti-condensation pipes. The heat exchange medium flows through the opened anti-condensation pipes, increasing the temperature around the anti-condensation pipes. The anti-condensation pipes prevent condensation by releasing the heat of the heat exchange medium.

[0048] According to the refrigeration system of this application, there are multiple circulation branches, each circulation branch is equipped with an anti-condensation pipe, and each anti-condensation pipe can independently prevent condensation. In the equipment, each circulation branch can be arranged in different positions, and the switching valve 130 opens the corresponding outlet according to the anti-condensation requirements of each position, so that the corresponding anti-condensation pipe can prevent condensation. This can prevent the generation of excess heat during condensation prevention and avoid increasing the energy consumption of the equipment.

[0049] In some embodiments, at least one circulation branch is provided with a bypass pipe, the input end of which is connected to the outlet of the switching valve 130 and is connected in parallel with the anti-condensation pipe.

[0050] When the anti-condensation pipes in the circulation branch are not connected, that is, there is no need to prevent condensation in the refrigeration system, the heat exchange medium discharged from the condenser 120 flows through the bypass pipe directly into the throttling element and participates in the refrigeration work, thereby realizing the full utilization of the heat exchange medium.

[0051] In some embodiments, each anti-condensation pipe is provided with a bypass pipe, thereby allowing the bypass pipe to be opened when anti-condensation is not required, while the anti-condensation pipe is closed, preventing the anti-condensation pipes of the freezer and / or refrigerator compartments from being continuously opened, which would cause an increase in the heat load of the compartments.

[0052] Taking a refrigerator as an example, a refrigerator cabinet typically has a freezer compartment and a refrigerator compartment. The cabinet is equipped with the aforementioned refrigeration system, with corresponding circulation branches in both the freezer and refrigerator compartments. The temperature in the freezer compartment is lower than that in the refrigerator compartment, and the temperature difference between the freezer compartment and the external environment is greater than that between the refrigerator compartment and the external environment. The risk of condensation differs between the freezer and refrigerator compartments. Anti-condensation pipes release heat to reduce the temperature difference between the freezer / refrigerator compartments and the external environment, thus preventing condensation. The basic structure and principles of refrigerators are based on mature existing technologies and will not be elaborated upon here.

[0053] In some embodiments, the refrigeration system includes two circulation branches. The first circulation branch includes a first anti-condensation pipe 141 and a first bypass pipe 142. The second circulation branch includes a second anti-condensation pipe 143 and a second bypass pipe 144. Each outlet of the switching valve 130 is connected to the inlet of the first anti-condensation pipe 141, the inlet of the first bypass pipe 142, the inlet of the first anti-condensation pipe 143, and the inlet of the second bypass pipe 144, respectively. The outlet of the first anti-condensation pipe 141 is connected to the outlet of the first bypass pipe 142, and the outlet of the first anti-condensation pipe 143 is connected to the outlet of the second bypass pipe 144.

[0054] In some embodiments, a one-in-four-out 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.

[0055] When the switching valve 130 is connected to the inlet and the first outlet 131, the heat exchange medium flows through the first anti-condensation pipe 141, and anti-condensation is performed by the first anti-condensation pipe 141; when the switching valve 130 is connected to the inlet and the second outlet 132, the heat exchange medium flows through the first bypass pipe 142, and anti-condensation is not performed in the first circulation branch; when the switching valve 130 is connected to the inlet and the third outlet 133, the heat exchange medium flows through the third anti-condensation pipe, and anti-condensation is performed by the first anti-condensation pipe 143; when the switching valve 130 is connected to the inlet and the fourth outlet 134, the heat exchange medium flows through the second bypass pipe 144, and anti-condensation is not performed in the second circulation branch.

[0056] By controlling the flow of the inlet and different outlets of the switching valve, the anti-condensation pipes in each cycle braking can be switched to perform anti-condensation actions, thus achieving flexible control of the anti-condensation function.

[0057] As an example, the second circulation branch is equipped with a second throttling element 152, the first circulation branch is equipped with a first throttling element 151 and a first evaporator 161, and the main circulation branch is equipped with a second evaporator 162. The input end of the first throttling element 151 is connected to the output ends of the first anti-condensation pipe 141 and the first bypass pipe 142, respectively. 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 connected to the output ends of the first anti-condensation pipe 143 and the second bypass pipe 144, respectively. The output end of the second throttling element 152 is connected to the output end of the first evaporator 161 and the input end of the second evaporator 162, respectively. The output end of the second evaporator 162 is connected to the air inlet of the compressor 110.

[0058] like Figure 2 As shown, an embodiment of this application provides a control method for controlling the aforementioned refrigeration system. In this embodiment, the control method includes steps 10 and 20.

[0059] Step 10: Obtain the relative humidity of the environment where the refrigeration system is located;

[0060] Step 20: When a cooling request is detected in the circulation branch of the refrigeration system and the relative humidity is greater than or equal to the reference humidity corresponding to the circulation branch, control the anti-condensation pipe corresponding to the circulation branch to be turned on.

[0061] The embodiments of this application provide a control method. 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 embodiments of this application will be described below with the controller as the execution subject as an example.

[0062] relative humidity This refers to the ratio of the actual water vapor pressure in the air to the saturated water vapor pressure at the given temperature. It reflects the ratio of the mass of water vapor in moist air to the mass of water vapor in saturated air at the same temperature and pressure. The environment in which the refrigeration system operates refers to the outdoor humidity during the time the doors of each compartment of the refrigeration equipment are closed.

[0063] It is understandable that, since all compartments of the refrigeration equipment are located in the same space, the relative humidity outside the doors of each compartment is... The relative humidity is basically the same in each compartment of the same refrigeration equipment at the same time, therefore it is generally considered that the relative humidity of the environment in each compartment is the same at the same time. same.

[0064] In some embodiments, the refrigeration equipment may be equipped with a humidity sensor connected to a controller to detect the relative humidity of the environment in which the refrigeration system is located. The detected results are then transmitted to the controller. The controller can acquire the relative humidity measured by the humidity sensor.

[0065] The refrigeration system can be equipped with temperature sensors to detect the actual temperature inside the rooms and transmit the results to the controller. The controller stores reference temperatures for each room when it is in refrigeration mode. When the actual temperature of one or more rooms exceeds the reference temperature, the controller generates a corresponding cooling request.

[0066] After the controller generates a corresponding cooling request, the refrigeration system starts to run, and the heat exchange medium circulates in each component. Therefore, the anti-condensation conditions are usually determined after confirming that each room has generated a cooling request.

[0067] The reference humidity for each circulation branch can be measured 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, therefore the reference temperatures for each compartment will also differ. Of course, the reference humidity for each compartment may also be related to the region where the refrigeration equipment is located and the season; therefore, it needs to be set according to specific circumstances during actual use.

[0068] Each circulation branch is located in a different room. When the controller detects a cooling request from one or more rooms and the relative humidity of the corresponding room is greater than or equal to the reference humidity of the circulation branch, it controls the anti-condensation pipe of the corresponding circulation branch to be turned on to prevent condensation.

[0069] According to the control method of this application, the refrigeration system is provided with multiple circulation branches, each circulation branch is provided with an anti-condensation pipe, and each anti-condensation pipe can independently prevent condensation. In the equipment, each circulation branch can be arranged in different positions. The controller controls the switching valve 130 to open the corresponding outlet according to the anti-condensation requirements of each position, so that the corresponding anti-condensation pipe can prevent condensation. This can prevent the generation of excess heat during anti-condensation and avoid increasing the energy consumption of the equipment.

[0070] Taking a refrigerator as an example, the refrigerator compartment has a first circulation branch, and the freezer compartment has a second circulation branch. The controller stores a first reference value RH1 for the refrigerator compartment and a second reference value RH2 for the freezer compartment. When there is a cooling request in each compartment, the controller compares the acquired relative humidity with the first reference value RH1 and the second reference value RH2 respectively.

[0071] There is a cooling request in the refrigerator compartment corresponding to the first circulation branch, and the relative humidity is... When the humidity is greater than or equal to the first reference humidity RH1, the refrigerator compartment needs to be protected against condensation. The controller drives the switching valve 130 to open the inlet and the first outlet 131, so that the first anti-condensation pipe 141 corresponding to the refrigerator compartment is opened.

[0072] There is a cooling request in the freezer compartment corresponding to the second circulation branch, and the relative humidity is... When the humidity is greater than or equal to the second reference humidity RH2, the freezer compartment needs to be protected against condensation. The controller drives the switching valve 130 to open the inlet and the third outlet 133, so that the second anti-condensation pipe 143 corresponding to the freezer compartment is opened.

[0073] In some embodiments, a bypass pipe is connected in parallel to the anti-condensation 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 less than the reference humidity corresponding to the circulation branch, controlling the bypass pipe corresponding to the circulation branch to be turned on.

[0074] There is a cooling request in the refrigerator compartment corresponding to the first circulation branch, and the relative humidity is... When the humidity is less than the first reference humidity RH1, the refrigerator compartment does not need to be protected against condensation. The controller drives the switching valve 130 to open the inlet and the second outlet 132, so that the first bypass pipe 142 corresponding to the refrigerator compartment is opened.

[0075] There is a cooling request in the freezer compartment corresponding to the second circulation branch, and the relative humidity is... When the humidity is less than the second reference humidity RH2, the freezer compartment does not need to be protected against condensation. The controller drives the switching valve 130 to open the inlet and the fourth outlet 134, so that the second bypass pipe 144 corresponding to the freezer compartment is open.

[0076] When the relative humidity of the environment does not meet the anti-condensation conditions, the anti-condensation pipe is closed and the corresponding bypass pipe is opened, so that the heat exchange medium continues to participate in the refrigeration work and avoids the generation of excess heat.

[0077] In some embodiments, the control method further includes: acquiring the operating parameters of the loop branch; and controlling the loop branch to close when the operating parameters meet the shutdown conditions.

[0078] The operating parameters of the circulation branch can be the actual temperature of the room corresponding to each circulation branch, which can be measured by the temperature sensor installed in the refrigeration system.

[0079] The controller has pre-stored the refrigeration shutdown reference temperature T1 and the freezer shutdown reference temperature T2. When the actual temperature of the refrigeration compartment 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 compartment is greater than or equal to the freezer shutdown reference temperature T2, the controller controls the second circulation branch to close.

[0080] When the temperature in the room reaches the shutdown reference temperature of each room, it indicates that the risk of condensation has been eliminated. The control circulation branch is then closed, which can both prevent the anti-condensation pipe from generating excess heat and reduce energy consumption.

[0081] In some embodiments, the reference humidity is different for different circulation branches.

[0082] Normally, the temperature in the freezer compartment is lower than that in the refrigerator compartment, and the temperature difference between the freezer compartment and the external environment is greater than that between the refrigerator compartment and the external environment. Condensation easily forms in the refrigerator compartment under high humidity, while condensation easily forms in the freezer compartment under medium to low humidity. Therefore, the second anti-condensation pipe 143 needs to be open under medium to low humidity conditions, while the first anti-condensation pipe 141 only needs to be open under high humidity conditions. Consequently, the first reference temperature of the circulation branch in the refrigerator compartment is higher than the second reference temperature of the circulation branch in the freezer compartment.

[0083] like Figure 3 As shown, with Figure 1 Taking the refrigeration system shown as an example, an example of implementing the anti-condensation process is as follows:

[0084] After the refrigerator is powered on and starts running, the temperature sensor and humidity sensor 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.

[0085] The controller first determines the cooling request of the refrigerator compartment. If the refrigerator compartment has a cooling request, it determines the relationship between the relative humidity of the surrounding environment and the first reference humidity RH1. If the relative humidity is greater than or equal to the first reference humidity RH1, the controller controls the switching valve 130 to open the inlet and the first outlet 131. If the relative humidity is less than the first reference humidity RH1, the controller controls the switching valve 130 to open the inlet and the second outlet 132.

[0086] If there is no cooling request in the refrigerator compartment, the cooling request in the freezer compartment is determined. If there is a cooling request in the freezer compartment, the relative humidity of the surrounding environment is compared with the second reference humidity RH2. If the relative humidity is greater than or equal to the second reference humidity RH2, the controller controls the switching valve 130 to open the inlet and the third outlet 133. If the relative humidity is less than the second reference humidity RH2, the controller controls the switching valve 130 to open the inlet and the fourth outlet 134.

[0087] If there is no cooling demand in the freezer compartment, the controller continues to control the temperature and humidity sensors to take measurements and re-evaluate the situation.

[0088] An embodiment of this application provides a control device for controlling the aforementioned refrigeration system. The control device includes an acquisition module and a drive module. The acquisition module is used to acquire the relative humidity of the environment in which the refrigeration system is located; the drive module is used to control the anti-condensation pipe corresponding to the circulation branch to conduct when a cooling request is detected in the circulation branch of the refrigeration system and the relative humidity is greater than or equal to the reference humidity corresponding to the circulation branch.

[0089] In some embodiments, the acquisition module acquires the relative humidity of the environment in which the refrigeration system is located; when the drive module detects a cooling request from the circulation branch in the refrigeration system and the relative humidity is greater than or equal to the reference humidity corresponding to the circulation branch, it controls the anti-condensation pipe corresponding to the circulation branch to be turned on.

[0090] In some embodiments, when the drive module detects a cooling request from a circulation branch in the refrigeration system and the relative humidity is less than the reference humidity corresponding to the circulation branch, it controls the bypass pipe corresponding to the circulation branch to be turned on.

[0091] In some embodiments, the acquisition module can also acquire the operating parameters of the loop branch, and the drive module controls the loop branch to close when the operating parameters meet the shutdown conditions.

[0092] According to the control device of this application, the refrigeration system is provided with multiple circulation branches, each circulation branch is provided with an anti-condensation pipe, and each anti-condensation pipe can independently prevent condensation.
