  • the refrigerating and freezing device of the present invention raises the evaporator temperature of the refrigerating evaporator by decreasing the operating frequency of the compressor during refrigeration of the non-refrigerating compartment, so that the evaporator temperature of the refrigerating evaporator is higher than the compartment temperature inside the refrigerating compartment while satisfying the refrigeration demand of the non-refrigerating compartment.
  • the outside water vapor entering the freezing compartment through the door seal and the moisture (e.g., moisture volatilized from the ingredients) in the freezing compartment will condense in the freezing compartment at the lower temperature instead of condensing at the freezing evaporator, thereby effectively increasing the moisture content in the freezing compartment, increasing the humidity in the freezing compartment, and avoiding that the preservation effect of the ingredients will be affected by the lower humidity in the freezing compartment.
  • the moisture e.g., moisture volatilized from the ingredients
  • the present invention realizes the effect of humidifying and moisturizing the freezer room by controlling the operating frequency of the compressor on the basis of the original structure of the refrigerating and freezing device, and does not require the addition of any auxiliary structure, and thus does not have any effect on the original structure of the refrigerating and freezing device and the capacity of storage, and is convenient for application in practice.
  • the refrigerating and freezing device further comprises a refrigerating fan for inducing a cooling airflow generated by the refrigerating evaporator to flow to the refrigerating compartment when the refrigerating compartment is refrigerated.
  • the refrigeration fan is usually stopped when the non-refrigerated compartment is being cooled.
  • the present invention sets the refrigeration fan to operate continuously during non-freezer room cooling, when water vapor formed by sublimation of a portion of the frost on the surface of the refrigeration evaporator is induced by the refrigeration fan to enter the lower temperature freezer room, further increasing the rate of increase of the moisture in the freezer room, and thereby increasing the rate of humidification of the freezer room.
  • the Refrigerator-freezer unit device (1) comprises a casing (10) and a refrigeration system (20).
  • the casing (10) defines a freezing compartment (11) and at least one non-freezing compartment. It is understood that the freezing compartment (11) is used as a storage compartment for freezing purposes, while the non-freezing compartment is used for non-freezing storage, such as for refrigeration or variable temperature storage. Typically, the temperature inside the non-freezing compartment is higher than that in the freezing compartment (11).
  • the refrigeration system (20) includes, connected in sequence to form a circuit, a compressor (21), a condenser (22), a solenoid valve (23), a freezing capillary tube (24), and a freezing evaporator (25).
  • the freezing capillary tube (24) has parallel branches to provide cooling for the above-mentioned at least one non-freezing compartment, each comprising a non-freezing capillary tube and a non-freezing evaporator connected in series. It should be noted that the terms "series” and “parallel” used in this invention refer to the physical series and parallel connections in the refrigerant flow path, not to the series and parallel in the electrical circuit structure.
  • the solenoid valve (23) is set to connect the condenser (22) and the non-freezing branch corresponding to that non-freezing compartment.
  • the refrigerant flowing out of the compressor (21) passes sequentially through the condenser (22), the solenoid valve (23), the non-freezing evaporator and capillary tube of the non-freezing branch, and the freezing evaporator (25), before returning to the compressor (21).

  • the freezing compartment (11) is not an absolutely sealed compartment.
  • the outside air carrying moisture enters the freezing compartment (11) through the door seal; moisture evaporates from food items inside the freezing compartment (11); after the food items in the freezing compartment (11) are frozen, a small amount of moisture on the surface of the food items sublimates; and a small amount of frost formed on the surface of the freezing evaporator (25) also sublimates.
  • the Refrigerator-freezer unit device (1) inherently has various moisture sources that can be used for moisturizing or humidifying the freezing compartment (11). If these moisture sources can be effectively used for moisturizing or humidifying the freezing compartment (11), then there is no need to set up any other humidifying devices.
  • frost rarely forms inside the storage compartments but mainly on the evaporators. This is due to the temperature of the evaporators being generally lower than that of the storage compartments. That is to say, water vapor typically accumulates and condenses at the lower temperature locations. Therefore, if the compartment temperature inside the freezing compartment is lower than the temperature of the evaporator at the freezing evaporator, water vapor will gather inside the freezing compartment. This can effectively moisturize or increase the humidity of the freezing compartment.
  • the invention specifically proposes a control method for a Refrigerator-freezer unit device, which includes the following steps:
  • Refrigerator-freezer unit device When the Refrigerator-freezer unit device is in a cooling state for any non-freezing compartment, reduce the operating frequency of the compressor. This action raises the temperature of the freezing evaporator above the compartment temperature inside the freezing compartment. Consequently, the moisture inside the freezing compartment is retained, and moisture at the freezing evaporator enters the freezing compartment, thereby increasing its humidity.
  • the operating frequency of the compressor is lowered to increase the temperature of the freezing evaporator. While satisfying the cooling needs of the non-freezing compartment, this ensures that the temperature of the freezing evaporator is higher than the compartment temperature inside the freezing compartment. At this time, external water vapor entering the freezing compartment through the door seal and moisture inside the freezing compartment (such as vapor from unfrozen food items, sublimated moisture from frozen food surfaces, etc.) will condense inside the colder freezing compartment rather than at the freezing evaporator. Thus, effectively increasing the moisture content inside the freezing compartment and improving its humidity. This avoids the issue of low humidity inside the freezing compartment affecting the preservation of food items.
  • this invention improves the humidity of the freezing compartment by controlling the operating frequency of the compressor based on the existing structure of the Refrigerator-freezer unit device, without the need for any auxiliary structures. Therefore, it does not impact the original structure and storage capacity of the device and is easy to apply in practice.
  • the approach to moisturizing and humidifying the freezing compartment proposed by this invention is completely different from the existing techniques, featuring an innovative design and significant effectiveness, with a promising practical application prospect.
  • FIG. 3 presents a schematic flowchart of the control method for a Refrigerator-freezer unit device according to a specific embodiment of this invention.
  • the control method includes the following steps:
  • the compressor (21) consistently operates at the reduced operating frequency to continuously moisturize or humidify the freezing compartment (11).
  • the Refrigerator-freezer unit device (1) includes a freezing fan (30) used to direct the cooling airflow generated by the freezing evaporator (25) into the freezing compartment (11) during cooling.
  • the control method further includes:
  • the freezing fan (30) is usually stopped during the cooling of the non-freezing compartment.
  • the freezing fan (30) is set to continuously operate during the cooling period of the non-freezing compartment. At this time, some of the frost sublimating from the surface of the freezing evaporator (25) quickly enters the colder freezing compartment (11) under the action of the freezing fan (30), thereby increasing the rate of moisture addition and humidification in the freezing compartment (11).
  • FIG. 4 illustrates another specific embodiment of the control method for a Refrigerator-freezer unit device, referring to Figure 4 .
  • the control method includes:
  • the freezing fan (30) is activated after the operating frequency of the compressor (21) is reduced. It should be understood that in some alternative embodiments, the activation of the freezing fan (30) may occur simultaneously with the reduction of the operating frequency of the compressor (21).
  • the rotational speed of the freezing fan (30) does not need to be high. Accordingly, in some embodiments, when the Refrigerator-freezer unit device (1) is in a cooling state for any non-freezing compartment, the rotational speed of the freezing fan (30) is lower than its set speed when the Refrigerator-freezer unit device (1) is in a cooling state for the freezing compartment. This configuration facilitates the quick transfer of sublimated frost from the freezing evaporator (25) into the freezing compartment (11) while preventing excessive airflow, which could raise the temperature inside the freezing compartment (11) too much.
  • the operating frequency of the compressor (21) cannot be too low. Therefore, in some embodiments, when the Refrigerator-freezer unit device (1) is in a cooling state for any non-freezing compartment, the operating frequency of the compressor (21) is set between its lowest operating frequency and the set operating frequency when the Refrigerator-freezer unit device (1) is in a cooling state for the freezing compartment. This ensures that while the non-freezing compartment's cooling requirements are met, the temperature of the freezing evaporator (25) is higher than the compartment temperature inside the freezing compartment (11), thereby achieving the goal of moisturizing or humidifying the freezing compartment (11).
  • the operating frequency of the compressor (21) is 3 to 17 hertz lower than the aforementioned set operating frequency.
  • the evaporator temperature of the freezing evaporator (25) can be slightly higher than the temperature inside the freezing compartment (11). This ensures maximum cooling efficiency and effectiveness for the non-freezing compartments while minimizing the possibility of excessive temperature rise within the freezing compartment (11).
  • the operating frequency of the compressor (21) can be 3, 5, 7, 9, 11, 13, 15, or 17 hertz lower than the operating frequency of the compressor (21) during the cooling period of the freezing compartment.
  • the operating frequency of the compressor (21) is 8 to 12 hertz lower than the above-mentioned set operating frequency.
  • control the control method of this invention also includes: When the temperature inside the non-freezing compartment, which is in a cooling state, reaches its set temperature, and if the temperature inside the freezing compartment (11) is higher than its set temperature, control the solenoid valve (23) to switch to the cooling state for the freezing compartment (11) and increase the operating frequency of the compressor (21) to enable the freezing compartment (11) to reach its set temperature more rapidly.
