If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0056] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0057] The embodiments of the present invention provide a valve system, a refrigeration device, a refrigeration method and a computer-readable storage medium. By setting a first valve and a second valve, the connection between the condenser and the evaporator of the refrigeration device can be switched according to different usage scenarios, and can effectively adapt to refrigeration systems in different modes. In a high-humidity environment, an anti-condensation pipe can be connected to avoid condensation in the refrigeration device, thereby improving the refrigeration efficiency of the refrigeration device, shortening the refrigeration time, and effectively reducing the energy consumption of the refrigeration device.

[0058] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0059] See also Figure 1 , Figure 1FIG. 1 is a schematic diagram showing a valve system according to an embodiment of the first aspect of the present invention. Figure 1 As shown, the valve system includes: a first valve 100 and a second valve 200, the first valve 100 is provided with a first inlet 110, a first outlet 120 and a second outlet 130, the second valve 200 is provided with a second inlet 210, a third inlet 220 and a plurality of third outlets 230; the first outlet 120 is used to be connected to the second inlet 210, the second outlet 120 is used to be connected to the third inlet 220 through an anti-condensation pipe 140, the first inlet 110 is used to be connected to the condenser 300, and the plurality of third outlets 230 are used to be connected to the evaporator 400 through a throttling device 240.

[0060] It is understandable that the valve system provided in this embodiment can be applied to refrigerators, air conditioners and other refrigeration equipment to control the flow of refrigerant in the refrigeration equipment, so that the refrigeration equipment can be adjusted under different refrigeration environments, effectively reducing the energy consumption of the refrigeration equipment. In actual applications, the first valve 100 and the second valve 200 are both electric switching valves. The main function of the electric switching valve of the refrigerator is to control the flow direction of the refrigerator refrigerant. Under its normal operation, different room temperatures achieve different refrigeration effects, and the refrigerator can be divided into different refrigeration compartments, such as a cold storage compartment, a freezing compartment, etc. Without this valve system, the refrigerator will not be able to adjust the flow of the refrigerant according to different application scenarios, and the temperature control and energy saving effects cannot be achieved.

[0061] In practical applications, in the circulation device of refrigeration equipment, such as air conditioning pipelines and refrigerator refrigeration pipelines, electric switching valves are usually used as control components to change the flow path of the refrigerant. Among them, the electric switching valve drives the motor rotor to rotate by using the stator component, and the motor rotor drives the slider to rotate. The slider rotates relative to the slide plate. The slider is provided with a groove or a hole or a slot. When the groove or the hole or the slot is aligned with the valve port on the slide plate, the outlet pipe connected to the hole is turned on. The slider is controlled to rotate by controlling the number of pulses input to the stator component to realize the on-off switching of an inlet pipe and two or more outlet pipes welded on the slide plate. The first valve 100 and the second valve 200 use electric switching valves, which can accurately control the conduction or disconnection between the first outlet 120 and the second inlet 210, the second outlet 120 and the third inlet 220, and the third outlet 230 and the throttling device 240, so that the valve system can adjust the refrigerant flowing through the first valve 100 and the second valve 200 according to different application scenarios to achieve the effect of temperature control and energy saving.

[0062] It is understandable that the second outlet 120 is connected to the third inlet 220 through the anti-condensation pipe 140, and the plurality of third outlets 230 are connected to the evaporator 400 through the throttling device 240. When the valve system connects the second outlet 120 and the third inlet 220, the refrigerant flowing through the first valve 100 and the second valve 200 passes through the anti-condensation pipe 140 located at the middle beam position of the refrigerator, heats the anti-condensation pipe 140, and evaporates the condensation near the middle beam position of the refrigerator, thereby preventing condensation from forming inside the refrigerator; when the valve system connects the first outlet 120 and the second inlet 210, the first valve 100 and the second valve 200 are directly connected, thereby preventing the refrigerant of the first valve 100 and the second valve 200 from passing through the anti-condensation pipe 140 to dissipate heat inside the refrigerator, reducing the heat load of the cabinet, and achieving the effect of energy saving and energy consumption reduction. According to the refrigeration demand of each refrigeration compartment, the opening of the third outlet 230 corresponding to the refrigeration compartment is adjusted, so that the flow rate of the refrigerant flowing through the evaporator 400 corresponding to the refrigeration compartment can be flexibly and quickly adjusted to achieve the effect of precise temperature control.

[0063] It can be understood that, in response to the need for energy saving in refrigerators, the embodiment of the present application adopts a method of connecting two electric switching valves in series, and achieves the purpose of short-circuiting the anti-dew pipe, changing the flow rate and maintaining the system pressure through different working modes of the valve system under the usage scenarios with small overall load and low humidity, thereby reducing operating energy consumption; in addition, in response to the need for improving the refrigeration speed of refrigerators, the embodiment of the present application adopts a method of connecting two electric switching valves in series, and increases the flow rate of the refrigerant during high-load operation to achieve the purpose of improving the refrigeration speed.

[0064] See also Figures 2 to 7 , Figures 2 to 7 FIG. 2 shows a schematic diagram of the structure of a refrigeration device provided by an embodiment of the second aspect of the present invention. Figures 2 to 7 As shown, the refrigeration device includes: a condenser 300, an evaporator 400 and the valve system as described above.

[0065] It is understandable that in order to cope with different application environments and usage costs, existing refrigerators are divided into single-system refrigerators and dual-system refrigerators. A dual-system refrigerator means that the refrigeration compartment and the freezer compartment are each equipped with an independent evaporator 400, and the refrigeration compartment and the freezer compartment are not connected, which effectively avoids the situation of odor contamination between the two refrigeration compartments, and the refrigeration speed is greatly improved, the performance is stronger, and the energy consumption and production cost are higher. A single-system refrigerator is a refrigerator compartment and a freezer compartment share an evaporator 400, and the gap between the two refrigeration compartments is interconnected.

[0066] Specifically, a single-system refrigerator is mainly composed of a compressor and a refrigeration compartment, and its refrigeration and freezing functions are concentrated in one system. The dual-system refrigerator separates the refrigeration and freezing functions, and is composed of two independent evaporators 400, a freezing compartment and a cold storage compartment. This design makes the dual-system refrigerator more flexible in refrigeration and freezing, and the temperature can be adjusted separately as needed to avoid mutual interference. The single-system refrigerator is more concise and practical, and is suitable for families with low freezing requirements. Secondly, from the perspective of storage space and layout, there are obvious differences between the single-system and dual-system refrigerators. The freezer and refrigerator compartments of the dual-system refrigerator are separately arranged, each with an independent door, making it more convenient to classify and store food. The single-system refrigerator combines the freezer and refrigerator compartments into one, and the capacity is relatively small. For families that need to store a large amount of food, dual-system refrigerators are more advantageous. For singles or small families, single-system refrigerators are more suitable.

[0067] See also Figures 2 to 5 , Figures 2 to 5 FIG. 2 shows a schematic diagram of a refrigeration device provided by another embodiment of the present invention. Figures 2 to 5 As shown, there are multiple evaporators 400 , and the refrigeration device is provided with refrigeration compartments corresponding to the evaporators 400 one by one.

[0068] It is understandable that the storage area of ​​a multi-system refrigerator is mainly divided into two parts: the freezer and the refrigerator. The main difference between them is the difference in temperature and humidity. The freezer is a low-temperature area in the refrigerator, usually below 0°C. The freezer is mainly used to store perishable foods such as meat, fish, seafood, ice cream, etc. The freezer can also store some non-perishable foods such as bread, cakes, fruits, etc. The refrigerator is a high-temperature area in the refrigerator, usually between 0-8°C. The refrigerator is mainly used to store milk, eggs, fruits, vegetables, juice, yogurt, cheese and other foods. The temperature of the refrigerator is moderate, which can extend the shelf life of food, but it is not suitable for storing perishable foods. Among them, the main function of the freezer is to store perishable foods. The temperature of the freezer is low, which can effectively inhibit the reproduction of bacteria and microorganisms in food and reduce the speed of food corruption. The freezer can also make ice cubes, ice cream and other foods. The main function of the cold storage room is to store perishable foods. The moderate temperature in the cold storage room can effectively slow down the spoilage of foods and keep them fresh. The cold storage room can also store some non-perishable foods, such as bread, cakes, fruits, etc.

[0069] See also Figure 2 and Figure 3 , Figure 2 and Figure 3 FIG. 2 shows a schematic diagram of a refrigeration device provided by another embodiment of the present invention. Figure 2 and Figure 3As shown, a plurality of evaporators 400 are connected in parallel, and the third outlet 230 , the throttling device 240 and the evaporator 400 correspond one to one.

[0070] It is understandable that when multiple evaporators 400 are connected in parallel, by opening the third outlet 230, the refrigerant can enter the evaporator 400 corresponding to the third outlet 230, and then quickly refrigerate the refrigeration compartment corresponding to the evaporator 400, thereby achieving a rapid refrigeration effect; by closing the third outlet 230, the refrigerant can stop entering the evaporator 400 corresponding to the third outlet 230, and then stop refrigerating the refrigeration compartment corresponding to the evaporator 400, thereby reducing the flow of the refrigerant and achieving an effect of reducing energy consumption. Specifically, multiple evaporators 400 can be respectively connected to the refrigeration compartments of the refrigerator, such as the freezer compartment and the refrigeration compartment of the refrigerator. At this time, the freezer compartment and the refrigeration compartment of the refrigerator can be independently temperature-controlled according to the refrigeration requirements, thereby improving the refrigeration efficiency and temperature-control flexibility of the refrigerator.

[0071] See also Figure 4 and Figure 5 , Figure 4 and Figure 5 FIG. 2 shows a schematic diagram of a refrigeration device provided by another embodiment of the present invention. Figure 4 and Figure 5 As shown, a plurality of evaporators 400 are connected in series, and the third outlet 230 , the throttling device 240 and the evaporator 400 correspond one to one.

[0072] It is understandable that a plurality of evaporators 400 are connected in series, and the corresponding evaporators 400 are connected in series to the refrigeration equipment according to the refrigeration demand of the refrigeration compartment. By opening the third outlet 230, the refrigerant can enter the evaporator 400 corresponding to the third outlet 230, and then quickly refrigerate the refrigeration compartment corresponding to the evaporator 400, wherein the evaporator 400 connected to the compressor 500 is connected to the second valve 200 through different throttling devices 240, which can ensure that the evaporator 400 continuously and stably refrigerates the corresponding refrigeration compartment, achieving a stable refrigeration effect; by closing the third outlet 230, the refrigerant can stop entering the evaporator 400 corresponding to the third outlet 230, and then stop refrigerating the refrigeration compartment corresponding to the evaporator 400, reducing the flow of the refrigerant, and achieving the effect of reducing energy consumption. Specifically, a plurality of evaporators 400 can be respectively connected to the refrigeration compartments of the refrigerator, such as the freezer compartment and the refrigeration compartment of the refrigerator. At this time, the evaporator 400 of the refrigerating compartment and the evaporator 400 of the freezing compartment are sequentially connected in series between the valve system and the compressor 500 to ensure that the refrigeration equipment continuously and stably refrigerates the freezing compartment, thereby improving the refrigeration efficiency and temperature control stability of the refrigerator.

[0073] See also Figure 6 and Figure 7 , Figure 6 and Figure 7 FIG. 2 shows a schematic diagram of a refrigeration device provided by another embodiment of the present invention. Figure 7 and Figure 8 As shown, there is only one evaporator 400 , and the evaporator 400 has a plurality of input ports, and the third outlet 230 , the throttling device 240 and the input ports correspond one to one.

[0074] It is understandable that, when the number of evaporators 400 is one, the refrigeration device is a single-system refrigerator, and the third outlet 230 is connected to the evaporator 400 through the throttling device 240. In practical applications, the throttling device 240 is a capillary tube of the refrigerator refrigeration system. The capillary tube is an important refrigeration component, and its function is to transfer the refrigerant from the high-pressure side to the low-pressure side, so that the refrigerant can evaporate into a gaseous state, absorb heat and cool the inside of the refrigerator. Therefore, by arranging capillaries of different calibers between multiple third outlets 230 and a single evaporator 400, the third outlet 230 can be opened and closed, so that the valve system is connected to the evaporator 400 through the throttling devices 240 with different flow rates, so as to adjust the flow rate of the refrigerant inside the refrigeration device and realize a fast and accurate temperature control function.

[0075] In another embodiment, a filter 310 is further provided between the first valve 100 and the condenser 300. The filter 310 adopts a drying and filtering combined design through internal design to perform drying and filtering operations on the refrigerant. Among them, the drying function of the filter 310 is mainly to provide chemical protection, including water absorption and acid absorption, the purpose of which is to avoid corrosion of the metal surface and decomposition of the refrigerant and lubricating oil. The filtering function of the filter 310 is mainly to provide physical protection, including intercepting particles and other impurities, which can effectively prevent filtered objects and soluble substances from entering the key components of the refrigeration equipment, thereby ensuring that the refrigeration equipment operates in the best state, ensuring the smooth operation of the refrigeration equipment, and also improving the service life of the refrigeration equipment.

[0076] See also Figure 8 , Figure 8 FIG. 4 is a flow chart showing a refrigeration control method provided by an embodiment of the third aspect of the present invention. Figure 8 As shown, the refrigeration control method includes the following steps:

[0077] Step S1000 : When the humidity of the compartment corresponding to the evaporator is greater than a preset humidity threshold, the valve system is controlled to open the second outlet 130 and the third inlet 220 and close the first outlet 120 and / or the second inlet 210 .

[0078] It is understandable that before the refrigeration control of the refrigeration equipment is performed, the refrigerant circulation system and valve system of the refrigeration equipment need to be installed and prepared for operation, such as ensuring that the evaporator 400, condenser 300, compressor 500, and valve system of the freezing compartment of the refrigerant circulation system are all operating normally, and the evaporator 400, the first valve 100, and the second valve 200 corresponding to the refrigeration compartment of the refrigeration equipment are all operating normally; the connection between the first valve 100, the second valve 200 and the evaporator 400, the condenser 300 is stable and reliable; the temperature acquisition unit in the refrigeration compartment can accurately obtain the temperature of the refrigeration compartment, and the humidity acquisition unit in the refrigeration compartment can accurately obtain the humidity of the refrigeration compartment; the switch control unit of the compressor 500 operates normally and can accurately control the compressor 500 to shut down and start. At the same time, when the compressor 500, the first valve 100, and the second valve 200 are operating, the refrigerant circulation system and the valve system communicate with the compressor 500, the temperature acquisition unit, and the humidity acquisition unit to obtain the temperature and humidity of the refrigeration compartment in real time.

[0079] It is understandable that when the humidity of the compartment corresponding to the evaporator 400 is greater than the preset humidity threshold, the anti-condensation pipe 140 needs to be heated by the refrigerant of the condenser to evaporate the condensation near the anti-condensation pipe 140 in the refrigerator to prevent condensation from forming inside the refrigerator. At this time, the second outlet 130 and the third inlet 220 need to be opened so that the first valve 100 and the second valve 200 are connected through the anti-condensation pipe 140.

[0080] See also Fig. 9 , Fig. 9 FIG. 5 shows a schematic diagram of a specific implementation process of the above step S1000. Fig. 9 As shown, step S1000 at least includes the following steps:

[0081] Step S1100: When the humidity of the compartment corresponding to the evaporator is greater than the humidity threshold, the refrigeration device enters the anti-dew mode.

[0082] It is understandable that after obtaining the current compartment humidity through the humidity collection component in the compartment of the refrigerator, the magnitude relationship between the humidity of the compartment corresponding to the evaporator and the humidity threshold can be determined. Among them, by obtaining the humidity of the compartment corresponding to the evaporator in real time and determining the humidity threshold of the compartment corresponding to the evaporator, it can be effectively ensured that the refrigeration equipment can perform anti-dew operation on the refrigeration compartment according to the humidity of the refrigeration compartment, thereby improving the correlation between the humidity of the refrigeration compartment and the working state of the anti-condensation pipe 140.

[0083] Step S1200 : Control the valve system to open the second outlet 130 and the third inlet 220 , so that the first valve 100 and the second valve 200 are connected through the anti-condensation pipe 140 , and the refrigerant passing through the condenser 300 heats the anti-condensation pipe 140 .

[0084] It is understandable that in order to ensure the anti-dew effect of the compartment corresponding to the evaporator 400, when the humidity of the compartment corresponding to the evaporator 400 is greater than the humidity threshold, in order to avoid condensation inside the refrigeration device, such as Figure 3 , Figure 5 and Figure 7 As shown, by controlling the valve system to open the second outlet 130 and the third inlet 220, the first valve 100 and the second valve 200 are connected through the anti-condensation pipe 140. At this time, the refrigerant passing through the first valve 100 passes through the second outlet 130, the anti-condensation pipe 140 and the third inlet 220 in sequence and enters the second valve 200. Since the anti-condensation pipe 140 is conducted, the refrigerant heats the anti-condensation pipe 140, so that the condensation near the anti-condensation pipe 140 exchanges heat with the anti-condensation pipe 140, and the condensation absorbs heat and evaporates, so as to achieve the effect of preventing condensation from forming. It can be understood that the process of performing anti-condensation operation on the refrigeration compartment of the refrigerator through the anti-condensation pipe 140 according to the humidity of the compartment corresponding to the evaporator 400 belongs to the prior art and will not be repeated here.

[0085] Step S1300: When the humidity of the compartment corresponding to the evaporator 400 is less than or equal to the humidity threshold, the refrigeration device enters a low energy consumption mode.

[0086] It is understandable that when the humidity of the compartment corresponding to the evaporator 400 is less than or equal to the humidity threshold, the humidity inside the refrigeration compartment of the refrigerator does not meet the conditions for condensation formation. At this time, if the anti-condensation pipe 140 continues to be turned on, the refrigerant heats the anti-condensation pipe 140, causing the condensation near the anti-condensation pipe 140 to exchange heat with the anti-condensation pipe 140, which will cause the anti-condensation pipe 140 to perform unnecessary heat dissipation on the refrigeration compartment and increase the energy consumption of the refrigeration equipment. Therefore, the anti-condensation pipe 140 needs to be short-circuited to achieve the effect of reducing energy consumption.

[0087] Step S1400 : controlling the valve system to open the first outlet 120 and the second inlet 210 , and close the second outlet 130 and / or the third inlet 220 , so that the first valve 100 and the second valve 200 are connected through the first outlet 120 and the second inlet 210 .

[0088] It is understandable that, in order to reduce the energy consumption of the compressor 500, when the humidity of the compartment corresponding to the evaporator 400 is less than or equal to the humidity threshold, in order to avoid causing unnecessary heat loss, such as Figure 2 , Figure 4 and Figure 6As shown, by controlling the valve system to open the first outlet 120 and the second inlet 210, the first valve 100 and the second valve 200 are directly connected. At this time, the refrigerant passing through the first valve 100 passes through the first outlet 120 and the second inlet 210 in sequence and enters the second valve 200. Since the second outlet 130 and / or the third inlet 220 are closed, the anti-condensation pipe 140 is short-circuited, and the refrigerant is prevented from heating the anti-condensation pipe 140, so as to achieve the effect of reducing the energy consumption of the compressor 500. It can be understood that the process of directly connecting the first valve 100 and the second valve 300 for refrigeration according to the humidity of the compartment corresponding to the evaporator 400 belongs to the prior art and will not be repeated here.

[0089] Step S2000 : When the temperature of the compartment corresponding to the evaporator 400 is greater than or equal to a preset temperature threshold, the valve system is controlled to open the third outlet 230 corresponding to the evaporator 400 .

[0090] It is understandable that the existing refrigerator determines whether to start the compressor to refrigerate the refrigerating compartment and the freezing compartment according to whether the temperature of the refrigerating compartment and the freezing compartment reaches the preset start-stop temperature. Specifically, when the temperature of the refrigerating compartment is higher than the start-up temperature, the refrigerating compartment requests refrigeration, and when the temperature of the refrigerating compartment is lower than the shutdown temperature, the refrigerating compartment stops requesting refrigeration; when the temperature of the freezing compartment is higher than the start-up temperature, the freezing compartment requests refrigeration, and when the temperature of the freezing compartment is lower than the shutdown point, the freezing compartment stops requesting refrigeration. Therefore, the start-up and shutdown temperatures of the existing refrigerator have a large variation range, which will cause the compressor 500 to start frequently, affecting the energy consumption and service life of the refrigerator. Through the valve system, the amount of refrigerant entering the evaporator 400 through the third outlet 230 is adjusted to achieve fast and accurate temperature control, effectively avoiding the frequent start and shutdown of the compressor 500.

[0091] See also Fig.10 and Fig.11 , Fig.10 and Fig.11 FIG. 5 shows a schematic diagram of a specific implementation process of the above step S2000. Fig.10 and Fig.11 As shown, step S2000 at least includes the following steps:

[0092] Step S2100: When the temperature of the compartment corresponding to the evaporator 400 is greater than or equal to the temperature threshold, the refrigeration device enters the rapid cooling mode.

[0093] It is understandable that when the temperature of the compartment corresponding to the evaporator 400 is greater than the preset temperature threshold, the third outlet 230 corresponding to the evaporator 400 needs to be opened so that the refrigerant passing through the first valve 100 enters the evaporator 400 through the second valve 200 to quickly cool the compartment of the refrigerator. At this time, the third outlet 230 corresponding to the evaporator 400 needs to be opened so that the evaporator 400 is connected to the second valve 200 to achieve a rapid cooling effect.

[0094] Step S2200 : controlling the valve system to open the third outlet 230 corresponding to the evaporator 400 .

[0095] It is understandable that, when there are multiple evaporators 400, Figures 2 to 4 As shown, by opening the third outlet 230 and connecting the corresponding evaporator 400, the refrigerant can enter the evaporator 400 through the third outlet 230 and perform a refrigeration operation with the corresponding refrigeration compartment to ensure the refrigeration effect of the refrigeration equipment. Figure 2 and Figure 3 As shown, when the evaporators 400 are connected in parallel, the evaporators 400 of the refrigerating compartment and the evaporators 400 of the freezing compartment can perform independent refrigeration operations according to the temperature of the refrigerating compartment and the temperature of the freezing compartment, so that the temperature of the refrigerating compartment and the temperature of the freezing compartment reach a preset temperature threshold. Figure 4 As shown, in the case where the evaporators 400 are connected in series, the evaporator 400 of the freezing compartment is located at the end of the evaporator 400 of the refrigerating compartment away from the valve system, and when the temperature of the refrigerating compartment is higher than the temperature threshold, the third outlet 230 corresponding to the evaporator 400 of the refrigerating compartment is opened, so that the evaporators 400 of the refrigerating compartment and the evaporators 400 of the freezing compartment cool the refrigerating compartment and the freezing compartment at the same time, thereby ensuring the refrigeration effect of the refrigerator.

[0096] Step S2300: When the temperature of the compartment corresponding to the evaporator 400 is greater than or equal to the temperature threshold, the refrigeration device enters the rapid cooling mode.

[0097] It can be understood that, consistent with the above step S2100, when there is only one evaporator 400, it is necessary to open and close the corresponding third outlet 230 to increase the amount of refrigerant entering the evaporator 400 so that the refrigeration equipment enters the rapid cooling mode.

[0098] Step S2400: Control the valve system to open the third outlet corresponding to the input port with the largest flow rate in the evaporator.

[0099] It is understandable that, when the number of evaporators 400 is one, Figure 6 and Figure 7As shown, a plurality of third outlets 230 are respectively connected to the evaporator 400 through corresponding throttling devices 240. When the temperature of the compartment corresponding to the evaporator 400 is greater than or equal to the temperature threshold, the third outlet 230 corresponding to the throttling device 240 with a larger flow rate can be opened, so that the valve system increases the amount of refrigerant between the second valve 200 and the evaporator 400, thereby increasing the refrigeration capacity of the evaporator 400 to the refrigeration compartment, and achieving a rapid refrigeration effect.

[0100] Step S3000: When the temperature of the compartment corresponding to the evaporator is lower than the temperature threshold, the valve system is controlled to close the third outlet corresponding to the evaporator.

[0101] It is understandable that, through the valve system, when the temperature of the compartment corresponding to the evaporator is less than the temperature threshold, the amount of refrigerant entering the evaporator 400 through the third outlet 230 is similarly adjusted to achieve fast and accurate temperature control, effectively avoiding frequent startup and shutdown of the compressor 500.

[0102] See also Fig.12 and Fig.13 , Fig.12 and Fig.13 FIG. 5 shows a schematic diagram of a specific implementation process of the above step S2000. Fig.12 and Fig.13 As shown, step S3000 at least includes the following steps:

[0103] Step S3100: When the temperature of the compartment corresponding to the evaporator is lower than the temperature threshold, the refrigeration device enters the normal refrigeration mode.

[0104] It is understandable that when the temperature of the compartment corresponding to the evaporator 400 is lower than the preset temperature threshold, the third outlet 230 corresponding to the evaporator 400 needs to be closed to prohibit the refrigerant passing through the first valve 100 from entering the evaporator 400 through the second valve 200, and stop refrigerating the compartment of the refrigerator. At this time, the third outlet 230 corresponding to the evaporator 400 needs to be closed so that the evaporator 400 is not connected to the second valve 200, thereby achieving an energy-saving effect.

[0105] Step S3200: Control the valve system to close the third outlet corresponding to the evaporator.

[0106] It is understandable that, when there are multiple evaporators 400, Figure 2 , Figure 3 and Figure 5 As shown, by closing the third outlet 230 and connecting the corresponding evaporator 400, the refrigerant stops entering the evaporator 400 through the third outlet 230, and stops the refrigeration operation with the corresponding refrigeration compartment, so as to ensure the energy saving effect of the refrigeration equipment. Figure 2 and Figure 3 As shown, when the evaporators 400 are connected in parallel, the evaporators 400 of the refrigerating compartment and the evaporators 400 of the freezing compartment can stop the refrigeration operation according to the temperature of the refrigerating compartment and the temperature of the freezing compartment, so that the temperature of the refrigerating compartment and the temperature of the freezing compartment reach the preset temperature threshold. Figure 5 As shown, in the case where the evaporators 400 are connected in series, the evaporator 400 of the freezing compartment is located at the end of the evaporator 400 of the refrigerating compartment away from the valve system. When the temperature of the refrigerating compartment is lower than the temperature threshold, the third outlet 230 corresponding to the evaporator 400 of the refrigerating compartment is closed, so that the evaporator 400 of the refrigerating compartment stops refrigerating. At the same time, the evaporator 400 of the freezing compartment continues to refrigerate the freezing compartment, thereby ensuring the refrigeration effect of the refrigerator while achieving the effect of energy saving and emission reduction.

[0107] Step S3300: When the temperature of the compartment corresponding to the evaporator is lower than the temperature threshold, the refrigeration device enters the normal refrigeration mode.

[0108] It is understandable that, consistent with the above step S3100, when there is only one evaporator 400, it is necessary to open and close the corresponding third outlet 230 to reduce the amount of refrigerant entering the evaporator 400 so that the refrigeration equipment enters the normal refrigeration mode.

[0109] Step S3400: Control the valve system to close the third outlet corresponding to the input port with the largest flow rate in the evaporator.

[0110] It is understandable that, when the number of evaporators 400 is one, Figure 6 and Figure 7 As shown, a plurality of third outlets 230 are respectively connected to the evaporator 400 through corresponding throttling devices 240. When the temperature of the compartment corresponding to the evaporator 400 is lower than the temperature threshold, the third outlet 230 corresponding to the throttling device 240 with a larger flow rate can be closed, so that the valve system reduces the amount of refrigerant between the second valve 200 and the evaporator 400, reduces the refrigeration capacity of the evaporator 400 to the refrigeration compartment, and achieves the effect of energy saving and emission reduction.
