[0037] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.
[0038] Combined Figures 2 to 3 As shown, the embodiments of the present disclosure provide a refrigeration device. The refrigeration device includes a refrigeration system. Generally, the refrigeration system may include a compressor 10, a heat dissipation condenser 20, a throttling device, and an evaporator 30 that are sequentially connected in the refrigerant flow direction. The three are sequentially connected through refrigerant pipelines. The compressor 10 increases the pressure and temperature of the refrigerant vapor through compression, compressing the low-temperature and low-pressure refrigerant vapor to a high-temperature and high-pressure state; the heat dissipation condenser 20 is a heat exchange device that uses the ambient cooling medium (air or water) to take away the heat of the high-temperature and high-pressure refrigerant vapor from the compressor 10, cooling and condensing the high-temperature and high-pressure refrigerant vapor into a high-pressure refrigerant liquid; and the evaporator 30 is located downstream of the heat dissipation condenser 20. The refrigerant liquid flowing into the evaporator 30 evaporates and refrigerates in the evaporator 30 to realize the refrigeration process of the refrigeration device, and the generated low-pressure vapor is sucked into the compressor 10 again, and so on, continuously circulating.
[0039] As Figure 1 shown, in the related art, the refrigerant of the refrigeration system flows through the condenser and then through the dew removal pipe 90. In this way, in a low-humidity environment, the refrigerant still flows through the dew removal pipe 90, increasing the energy consumption of the refrigeration equipment and reducing the refrigeration efficiency.
[0040] As Figure 2 and Figure 3 shown, the embodiment of the present disclosure provides a refrigeration system for a refrigeration device. The refrigeration system includes a compressor 10, a heat dissipation condenser 20, an evaporator 30, a first pipeline 40, and a second pipeline 50. The inlet of the heat dissipation condenser 20 is communicated with the outlet of the compressor 10; the evaporator 30 is connected between the outlet of the heat dissipation condenser 20 and the inlet of the compressor 10; the first pipeline 40 is communicated between the outlet of the heat dissipation condenser 20 and the inlet of the evaporator 30; the second pipeline 50 is arranged in parallel with the first pipeline 40 between the outlet of the heat dissipation condenser 20 and the inlet of the evaporator 30, and the second pipeline 50 is used for dew removal of the refrigeration device; wherein, the first pipeline 40 and the second pipeline 50 are selectively communicated.
[0041] In the embodiment of the present disclosure, the high-pressure refrigerant flowing out of the heat dissipation condenser 20 can flow into the evaporator 30 through the first pipeline 40 or the second pipeline 50. When the refrigeration device needs dew removal or has a risk of condensation, the second pipeline 50 is communicated. In this way, the high-temperature refrigerant flowing into the second pipeline 50 can heat up to increase the temperature of the target dew removal area, playing a role in preventing condensation. When the refrigeration device does not need to prevent condensation, the second pipeline 50 is disconnected and the first pipeline 40 is communicated. In this way, the refrigerant flowing out of the heat dissipation condenser 20 does not need to flow through the target dew removal area of the refrigeration device, so it will not increase the internal temperature of the refrigeration device, reduce the interference with the refrigeration temperature, and reduce the energy consumption.
[0042] Optionally, the refrigeration system further includes a three-way valve 60. The inlet of the three-way valve 60 is communicated with the outlet of the heat dissipation condenser 20. The first outlet of the three-way valve 60 is communicated with the inlet of the first pipeline 40, and the second outlet of the three-way valve 60 is communicated with the inlet of the second pipeline 50.
[0043] In the embodiment of the present disclosure, the outlet of the heat dissipation condenser 20, the inlet of the first pipeline 40, and the inlet of the second pipeline 50 are communicated through the three-way valve 60. In this way, adjusting the three-way valve 60 can adjust the flow direction of the refrigerant of the heat dissipation condenser 20 to the first pipeline 40 or the second pipeline 50, so as to realize the selective communication between the first pipeline 40 and the second pipeline 50.
[0044] Optionally, valves, such as solenoid valves, may be respectively provided at the outlet of the heat dissipation condenser 20 and the inlet of the first pipeline 40 and at the outlet of the heat dissipation condenser 20 and the inlet of the second pipeline 50. The control methods that can realize the connection and disconnection of the first pipeline 40 and the second pipeline 50 all belong to the optional embodiments of the present application.
[0045] Optionally, as Figure 3 shown, the refrigeration system further includes a first throttling device 70 and a second throttling device 80. The first throttling device 70 is connected between the outlet of the first pipeline 40 and the inlet of the evaporator 30; the second throttling device 80 is connected between the outlet of the second pipeline 50 and the inlet of the evaporator 30.
[0046] In the embodiment of the present disclosure, the first throttling device 70 is used to throttle the refrigerant flowing out of the first pipeline 40 so that the throttled refrigerant flows into the evaporator 30. The second throttling device 80 is used to throttle the refrigerant flowing out of the second pipeline 50 so that the throttled refrigerant flows into the evaporator 30. In this way, the refrigerant flowing out of the first pipeline 40 or the second pipeline 50 can be throttled by the throttling device to ensure the circulating flow of the refrigeration system.
[0047] It can be understood that the first pipeline 40 and the second pipeline 50 can also share a throttling device.
[0048] Optionally, the refrigeration system further includes a first drying filter, which is arranged between the outlet of the first pipeline 40 and the first throttling device 70 and is used to dry and filter the impurities flowing from the first pipeline 40 to the first throttling device 70 to avoid blocking the first throttling device 70.
[0049] Optionally, the refrigeration system further includes a second drying filter, which is arranged between the outlet of the second pipeline 50 and the second throttling device 80 and is used to dry and filter the impurities flowing from the second pipeline 50 to the second throttling device 80 to avoid blocking the second throttling device 80.
[0050] The embodiment of the present disclosure further provides a refrigeration device, which includes the refrigeration system of any one of the above embodiments.
[0051] The refrigeration device of the embodiment of the present disclosure includes the refrigeration system of any one of the above embodiments, so it has the beneficial effects of the refrigeration system of any one of the above embodiments, which will not be elaborated here.
[0052] Optionally, the refrigeration device further includes a box body and a door body. The box body defines a containing cavity with an opening; the door body is movably covered at the opening of the containing cavity. Specifically, the door body is rotatably covered at the opening of the containing cavity.
[0053] Optionally, the refrigeration device includes a partition board and a door beam. The partition board divides the space inside the box body into multiple refrigeration chambers. The door beam is arranged between adjacent containing cavities and is located in front of the partition board. Among them, the door beam is used to cooperate with the door body to open and close the door.
[0054] Optionally, the second pipeline 50 is disposed in a target dew removal area of the door body and / or the box body, and the target dew removal area includes a door beam; the refrigeration device further includes a heating wire 504 disposed on the door beam for dew removal of the refrigeration device.
[0055] In the embodiment of the present disclosure, the second pipeline 50 is disposed in the target dew removal area of the door body and / or the box body, so that the door body and / or the box body can be prevented from condensing. Among them, a heating wire 504 is also disposed at the door beam. During actual use, due to the large temperature difference and humidity difference at the door beam, it is easier for the door beam to condense. Therefore, when dew prevention is not required at other positions or the dew prevention effect of the second pipeline 50 at the door beam is poor, the heating wire 504 can be turned on to increase the temperature of the door beam, without the need for the entire second pipeline 50 to be connected. In this way, not only can the dew prevention of the door beam be achieved, but also the temperature rise at other positions can be avoided, resulting in an increase in the energy consumption of the refrigeration device.
[0056] Optionally, the door body includes a door body main body and a door seal, and the target dew removal area includes the door seal. Optionally, the door body main body further includes a door liner and a door shell, and the target dew removal area includes the door liner.
[0057] Optionally, the refrigeration device further includes a first detection device and a controller. The first detection device is used to detect the humidity of the environment where the refrigeration device is located; the controller is electrically connected to the three-way valve 60, the heating wire 504, and the first detection device, and the controller is configured to control the three-way valve 60 and the heating wire 504 to work according to the humidity of the environment where the refrigeration device is located.
[0058] In the embodiment of the present disclosure, the humidity of the environment where the refrigeration device is located has a great influence on whether the refrigeration device has a dew condensation trend. The controller controls the three-way valve 60 and the heating wire 504 according to the humidity of the environment where the refrigeration device is located, so that the refrigeration device can meet the new requirements for dew prevention in different humidity environments, ensuring the dew removal effect at low humidity and reducing the energy consumption of the refrigerator. When the humidity is high, it can ensure the function of dew removal, and can remove dew more accurately, quickly and efficiently.
[0059] Optionally, when the humidity of the environment where the refrigeration device is located is greater than or equal to a preset humidity, the controller is configured to control the heating wire 504 to work and control the three-way valve 60 to conduct the heat dissipation condenser 20 and the second pipeline 50.
[0060] In the embodiment of the present disclosure, when the environmental humidity is high, the risk of condensation of the refrigeration device is high. The controller controls the second pipeline 50 to conduct and also controls the heating wire 504 to work, so as to heat the target dew removal area in all directions and avoid condensation of the refrigeration device.
[0061] Optionally, after the controller controls the heating wire 504 to work and the three-way valve 60 conducts the heat dissipation condenser 20 and the second pipeline 50, the air controls the heating wire 504 to work at a low power.
[0062] In the disclosed embodiment, since the second pipeline 50 is connected, the heating wire 504 works at low power, plays an auxiliary role, can also achieve an anti-condensation effect, and can save energy consumption.
[0063] Optionally, when the humidity of the environment in which the refrigeration device is located is less than a preset humidity, the controller is configured to control the three-way valve 60 to connect the heat dissipation condenser 20 and the first pipeline 40 .
[0064] In the embodiment of the present disclosure, when the humidity of the environment in which the refrigeration equipment is located is low, the risk of condensation in the refrigeration equipment is low. The controller controls the heat dissipation condenser 20 and the first pipeline 40 to be connected, so that the refrigerant flowing out of the heat dissipation condenser 20 does not need to flow through the target decondensation area, thereby reducing the heat exchange between the refrigerant and the cold air in the refrigeration equipment, thereby reducing the impact of the second pipeline 50 on the temperature in the refrigeration equipment and reducing energy consumption.
[0065] Combination Figure 4 As shown, the embodiment of the present disclosure also provides a method for controlling a refrigeration device, comprising:
[0066] S401: The controller obtains the humidity of the environment in which the refrigeration equipment is located.
[0067] S402: When the humidity of the environment in which the refrigeration device is located is greater than or equal to the preset humidity, the controller controls the heating wire 504 to work, and controls the three-way valve to conduct the heat dissipation condenser and the second pipeline.
[0068] S403: When the humidity of the environment in which the refrigeration device is located is lower than the preset humidity, the controller controls the three-way valve to connect the heat dissipation condenser and the first pipeline.
[0069] In this way, the refrigeration device first obtains the ambient humidity of the refrigeration device through the first detection device. When the humidity is high, the second pipeline 50 and the heating wire 504 are controlled to work to quickly improve the problem of the target dew removal area and improve the anti-condensation effect. When the humidity is lower than the preset humidity, the controller controls the three-way valve 60 to conduct the heat dissipation condenser 20 and the first pipeline 40, so that the refrigerant does not need to flow through the refrigeration device, reducing the heat load and reducing energy consumption.
[0070] Optionally, the refrigeration equipment also includes a second detection device and a third detection device, the second detection device is used to detect the temperature of the environment in which the refrigeration equipment is located; the third detection device is arranged in the target dew removal area of the refrigeration equipment, and is used to detect the temperature of the target dew removal area; the controller is configured to calculate the dew point temperature of the environment in which the refrigeration equipment is located according to the humidity and temperature of the environment in which the refrigeration equipment is located, and control the operation of the heating wire 504 and the three-way valve 60 according to the dew point temperature of the environment in which the refrigeration equipment is located and the temperature of the target dew removal area.
[0071] In an embodiment of the present disclosure, a first detection device is configured to detect the humidity of the environment where the refrigeration device is located, and a second detection device is configured to detect the temperature of the environment where the refrigeration device is located. After the first detection device and the second detection device transmit the detected temperature and humidity to the controller, the controller calculates the dew point temperature of condensation in the current environment. A third detection device can detect the temperature of the target dew removal area, and then determine the difference between the temperature of the target dew removal area and the dew point temperature, so as to determine whether there is a condensation risk in the target dew removal area. The controller then controls the operation of the three-way valve 60 and the heating wire 504, which can accurately control the operation of the heating wire 504 and the connection of the second pipeline 50, save energy consumption, reduce the heat load, and improve the user experience.
[0072] Exemplarily, the first detection device is a humidity sensor, the second detection device is a temperature sensor, and the third detection device is a temperature sensor.
[0073] Optionally, after the three-way valve 60 conducts the heat dissipation condenser 20 and the second pipeline 50, when the difference between the temperature of the target dew removal area and the dew point temperature of the environment where the refrigeration device is located is greater than a preset difference, and the duration for which the difference between the temperature of the target dew removal area and the dew point temperature of the environment where the refrigeration device is located is greater than the preset difference is greater than a first duration, the controller controls the three-way valve 60 to connect the heat dissipation condenser 20 and the first pipeline 40, and turns on the heating wire 504 to make the heating wire 504 operate at a low power.
[0074] In an embodiment of the present disclosure, when the humidity of the external environment is greater than or equal to a preset humidity, after the controller controls the three-way valve 60 to conduct the heat dissipation condenser 20 and the second pipeline 50, the temperature of the target dew removal area gradually increases. When the difference between the temperature of the target dew removal area and the dew point temperature of the environment where the refrigeration device is located is greater than a preset difference, and the duration for which the difference between the temperature of the target dew removal area and the dew point temperature of the environment where the refrigeration device is located is greater than a first duration, it indicates that the temperature of the target dew removal area is relatively high and the condensation risk is relatively small. At this time, the heat dissipation condenser 20 and the first pipeline 40 are connected, the second pipeline 50 is disconnected, and the heating wire 504 is made to operate at a low power to maintain the temperature of the target dew removal area. In this way, it can not only prevent condensation, but also reduce the heat load of the refrigeration device and reduce energy consumption.
[0075] Combined Figure 5 As shown, an embodiment of the present disclosure further provides a method for controlling a refrigeration device, including:
[0076] S501. The controller obtains the humidity of the environment where the refrigeration device is located.
[0077] S502. When the humidity of the environment where the refrigeration device is located is greater than or equal to a preset humidity, the controller controls the heating wire to operate and controls the three-way valve to conduct the heat dissipation condenser and the second pipeline.
[0078] S503. When the difference between the temperature of the target dew removal area and the dew point temperature of the environment where the refrigeration equipment is located is greater than a preset difference, and the duration for which the difference between the temperature of the target dew removal area and the dew point temperature of the environment where the refrigeration equipment is located is greater than the preset difference is greater than a first duration, the controller controls the three-way valve to connect the heat dissipation condenser and the first pipeline, and turns on the heating wire so that the heating wire operates at a low power.
[0079] In the embodiment of the present disclosure, after the second pipeline 50 is connected to the condenser, the refrigerant flowing out of the condenser flows into the refrigeration equipment through the second pipeline 50 to raise the temperature of the target dew removal area of the refrigeration equipment to remove condensation. When the temperature of the target dew removal area is high and stable, the three-way valve 60 is switched to the first pipeline 40, which can reduce the heat exchange between the second pipeline 50 and the refrigeration equipment and reduce the energy consumption of the refrigeration equipment.
[0080] Optionally, after the controller controls the three-way valve 60 to connect the heat dissipation condenser 20 and the first pipeline 40, when the temperature of the target dew removal area is less than the dew point temperature of the environment where the refrigeration equipment is located, and the duration for which the temperature of the target dew removal area is less than the dew point temperature of the environment where the refrigeration equipment is located reaches a second duration, the controller controls the three-way valve 60 to connect the heat dissipation condenser 20 and the second pipeline 50.
[0081] In the embodiment of the present disclosure, after the controller controls the three-way valve 60 to connect the heat dissipation condenser 20 and the first pipeline 40, only the door beam in the target dew removal area is heated by the heating wire 504. When the temperature of the target dew removal area is less than the dew point temperature of the environment where the refrigeration equipment is located, and the duration for which the temperature of the target dew removal area is less than the dew point temperature of the environment where the refrigeration equipment is located reaches a second duration, it indicates that there is a risk of condensation in the target dew removal area. At this time, the controller controls the three-way valve 60 to connect the heat dissipation condenser 20 and the second pipeline 50, and the refrigerant flows in the second pipeline 50, so that the temperature of the target dew removal area rises, avoiding condensation due to the decrease in the temperature of the target dew removal area.
[0082] Combined with Figure 6 As shown, the embodiment of the present disclosure also provides a method for controlling a refrigeration equipment, including:
[0083] S601. The controller obtains the humidity of the environment where the refrigeration equipment is located.
