[0002] In the traditional control of the refrigerator, when there is a refrigeration request at least for the freezer, the compressor and the refrigeration fan are turned on at the same time, and the refrigeration fan promotes the circulation of cold air to achieve rapid cooling.

[0003] However, under the action of wind pressure generated by the refrigeration fan, the higher temperature gas in the refrigerated compartment is mixed with the lower temperature gas in the freezer compartment, and the mixed superheated gas flows through the evaporator, resulting in an increase in superheated gas in the evaporator, a shortening of the gas-liquid two-phase zone in the evaporator, and an increase in the superheated section, wherein the superheated section is the area where the liquid refrigerant has basically evaporated into gaseous refrigerant, and the evaporator heat exchange makes more use of the vaporization heat absorption of the liquid refrigerant. Due to the shortening of the gas-liquid two-phase zone in the evaporator, the heat exchange effect of the evaporator on the freezer compartment is reduced.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0030] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0031] The present application provides a refrigerator control method, referring to Figure 1 , Figure 1 This is a flow chart of a first embodiment of a refrigerator control method of the present invention, wherein the method comprises the following steps:

[0032] Step S10, detecting refrigeration requests of the refrigerating compartment and the freezing compartment;

[0033] Temperature sensors are arranged in the refrigeration compartment and the freezer compartment respectively. The real-time temperature of the refrigeration compartment or the freezer compartment is detected by the temperature sensor. When the real-time temperature of the refrigeration compartment or the freezer compartment is higher than the corresponding set refrigeration temperature, it is determined that there is a refrigeration request. For example, the set refrigeration temperature range of the refrigeration compartment is 3-4°C. When the real-time temperature of the refrigeration compartment is higher than 4°C, it means that the refrigeration compartment no longer meets the refrigeration requirements of refrigeration. Then there is a refrigeration request for the refrigeration compartment, and the refrigeration system works. When its temperature drops to the temperature range of 3-4°C, the system refrigeration stops. The refrigeration request for the freezer compartment is similar.

[0034] Step S20, detecting the surface temperature of the evaporator;

[0035] In this embodiment, temperature sensors are arranged in the middle section and outlet of the evaporator to detect the first surface temperature of the evaporator, which is the surface temperature of the middle section of the evaporator and is denoted as T1; and to detect the second surface temperature of the evaporator, which is the surface temperature of the evaporator outlet and is denoted as T2.

[0036] Step S30: controlling the refrigeration state of the refrigerator according to the refrigeration request and the surface temperature of the evaporator.

[0037] During the operation of the compressor, the refrigerant flows into the evaporator through the capillary throttling, absorbing heat and evaporating along the way. The heat exchange of the evaporator mainly utilizes the heat absorption of the vaporization of the liquid refrigerant, that is, the heat exchange effect of the liquid refrigerant is better than that of the gaseous refrigerant. When the refrigeration system starts working, the liquid refrigerant that enters the evaporator is generally liquid refrigerant. As the liquid refrigerant flows in the evaporator, the liquid refrigerant gradually vaporizes, and the temperature gradually increases from liquid to gas. Therefore, by monitoring the surface temperature of the evaporator, the state of liquid refrigerant accumulation can be qualitatively judged. Thus, according to the accumulation of liquid refrigerant, the refrigeration state of the refrigerator can be controlled. When a certain amount of liquid refrigerant accumulates, the heat exchange effect of the evaporator is better, and the power of the compressor is relatively reduced.

[0038] Through this embodiment, by monitoring the accumulation of liquid refrigerant in the evaporator, the refrigeration state of the refrigerator is controlled, the steady-state power consumption of the refrigerator is reduced, and the power consumption of the refrigerator is ensured to be maintained within a relatively low range.

[0039] In one implementation of this embodiment, controlling the refrigeration state of the refrigerator according to the refrigeration request and the surface temperature of the evaporator includes:

[0040] A31, when it is detected that there is a refrigeration request for both the freezing compartment and the refrigerating compartment, controlling the compressor to be in an on state and the refrigerating damper to be in an open state, and when the refrigerating damper is opened, the coldness of the freezing compartment is diffused to the refrigerating compartment through the refrigerating damper;

[0041] A32, reading a first surface temperature, where the first surface temperature is the surface temperature of the middle section of the evaporator;

[0042] A33, controlling the working state of the refrigeration fan according to the first surface temperature.

[0043] When there is a refrigeration request for both the freezer compartment and the refrigerator compartment, the compressor is controlled to be in an on state, the refrigerator damper is in an open state, and the coldness of the freezer compartment is diffused to the refrigerator compartment through the refrigerator damper.

[0044] Since the temperature of the freezing compartment is relatively low, the refrigerating compartment mainly relies on the coldness of the freezing compartment to cool down. Only a relatively small amount of accumulated liquid refrigerant is needed in the evaporator to meet the refrigeration demand of the refrigerating compartment. Therefore, in this embodiment, when both the freezing compartment and the refrigerating compartment have refrigeration requests, the compressor is controlled to be in the open state, the refrigerating damper is in the open state, and the refrigerating fan is in the closed state. Since there is no forced flow of gas in the compartment, the operating power of the compressor is reduced. Then, by reading the first surface temperature T1 of the middle section of the evaporator, the working state of the refrigerating fan is controlled according to the first surface temperature T1.

[0045] In this embodiment, when both the freezing compartment and the refrigerating compartment have refrigeration requests, the temperature of the middle section of the evaporator reflects the accumulation of liquid refrigerant in the evaporator, and controls the working state of the refrigerating fan, thereby supplying air to cool the refrigerating compartment, meeting the refrigerating compartment's refrigeration request and significantly reducing power consumption.

[0046] In this implementation manner, controlling the working state of the refrigeration fan according to the first surface temperature includes:

[0047] A331, determining whether the first surface temperature is lower than a first preset threshold;

[0048] A332: if the first surface temperature is lower than a first preset threshold, control the refrigeration fan to turn on; if the first surface temperature is higher than or equal to the first preset threshold, control the refrigeration fan to turn off.

[0049] Determine whether the first surface temperature (temperature of the middle section of the evaporator) T1 is lower than the first preset threshold; if the first surface temperature T1 is lower than the first preset threshold, it indicates that the refrigerant in the middle section of the evaporator is in a liquid state or a gas-liquid two-phase state, that is, the liquid refrigerant has accumulated to the middle section of the evaporator, the gas-liquid two-phase area accounts for a sufficient proportion, and the heat exchange effect of the evaporator is good. At this time, the refrigeration fan is turned on again, and the refrigeration fan can be further controlled to maintain the first speed (low speed) S1 to meet the initial higher heat load, and the power of the compressor is relatively low. In this embodiment, the first preset threshold can be set according to actual conditions or obtained through experiments. Preferably, the first preset threshold can be set to -10°C.

[0050] If the first surface temperature T1 is higher than or equal to the first preset threshold value, it means that the refrigerant in the middle section of the evaporator may be in the state of gaseous refrigerant. At this time, the gas-liquid two-phase area accounts for a small proportion, the superheated section accounts for a large proportion, and the heat exchange effect of the evaporator is not good. Then the refrigeration fan is controlled to be in the off state. The refrigeration fan is turned off, and the refrigerated compartment is cooled by natural convection. The gas in the refrigerated compartment and the freezer compartment does not circulate, thereby reducing the disturbance of the high-temperature gas in the refrigerated compartment. The heat load of the evaporator is relatively low, and the evaporator can accumulate more liquid refrigerant. When the liquid refrigerant accumulates to the middle section of the evaporator, the refrigeration fan is controlled to be turned on. When a certain amount of liquid refrigerant is accumulated, the refrigeration fan is turned on. At this time, the heat exchange coefficient is not significantly reduced, and the gas-liquid two-phase area is moderate. At this time, the amount of liquid refrigerant is moderate, and the power consumption of the compressor is low, which is beneficial to the power consumption. Compared with the simultaneous turning on of the refrigeration fan and the compressor, the instantaneous load of the compressor is large when it is turned on, and the instantaneous power is high in the initial stage. This embodiment can control the starting power to be reduced, and accumulate more refrigerant for cooling the air circulation after the refrigeration fan is turned on.

[0051] In another implementation of this embodiment, controlling the refrigeration state of the refrigerator according to the refrigeration request and the surface temperature of the evaporator includes:

[0052] B31, when it is detected that there is a refrigeration request only in the freezing compartment, the compressor is controlled to be in an on state, the refrigeration damper is in a closed state, and the refrigeration fan is operated at a first speed;

[0053] B32, reading a second surface temperature, where the second surface temperature is the surface temperature at the outlet of the evaporator;

[0054] B33, controlling the working state of the refrigeration fan according to the second surface temperature.

[0055] When there is a cooling request only in the freezing compartment, the compressor is controlled to be turned on, and there is no cooling request in the refrigerating compartment, indicating that the refrigerating compartment has reached the set refrigerating temperature, the refrigerating damper is controlled to be closed, and the freezing fan is controlled to run at the first speed S1.

[0056] In this embodiment, since the required temperature of the freezer compartment is relatively low and more cooling capacity is required, it is necessary to increase the rotation speed of the freezing fan to accelerate the flow of air and promote the cooling of the freezer compartment. If the rotation speed is directly increased, the amount of gaseous refrigerant will increase and the power consumption of the compressor will be high. Therefore, in order to avoid forced air flow, which causes higher-temperature gas to flow into the evaporator, affecting the heat exchange effect of the evaporator and increasing the power of the compressor, this embodiment first controls the freezing fan to operate at a low rotation speed S1, and then reads the second surface temperature T2 of the evaporator outlet, controls the working state of the freezing fan according to the second surface temperature T2, reflects the accumulation of liquid refrigerant in the evaporator according to the temperature of the evaporator outlet, waits for the evaporator outlet temperature to further decrease, accumulates liquid refrigerant as much as possible, and then increases the fan speed, the power will not increase significantly, and can adapt to the high load caused by the increase in fan speed.

[0057] In this embodiment, controlling the working state of the refrigeration fan according to the second surface temperature includes:

[0058] B331, determining whether the second surface temperature is lower than a second preset threshold;

[0059] B332: if the second surface temperature is lower than a second preset threshold, the refrigeration fan is controlled to increase its speed from the first speed to the second speed; if the second surface temperature is higher than or equal to the second preset threshold, the refrigeration fan is controlled to maintain its speed at the first speed.

[0060] Determine whether the second surface temperature (evaporator outlet temperature) T2 is lower than the second preset threshold; if the second surface temperature T2 is lower than the second preset threshold, it indicates that the refrigerant at the evaporator outlet is in a liquid state or a gas-liquid two-phase state, that is, the liquid refrigerant has accumulated to the evaporator outlet position, the gas-liquid two-phase area accounts for a sufficient proportion, and the heat exchange effect of the evaporator is good, which can meet a higher heat load. At this time, the speed of the refrigeration fan is increased, and the refrigeration fan is controlled to increase from the first speed S1 to the second speed S2 to promote the cooling of the freezing compartment while avoiding excessive increase in the power of the compressor. In this embodiment, the second preset threshold can be set according to actual conditions or obtained through experiments. Optionally, the second preset threshold can be set to -10°C.

[0061] In this embodiment, if the second surface temperature T2 is higher than or equal to the second preset threshold value, it means that the refrigerant at the evaporator outlet may be in a gaseous refrigerant state. At this time, the accumulation of liquid refrigerant is insufficient, and the refrigeration fan is controlled to maintain the first speed S1 to reduce the circulation of high-temperature gas in the freezing chamber. The heat load of the evaporator is relatively low, and the evaporator can accumulate more liquid refrigerant. When the liquid refrigerant accumulates to the evaporator outlet, the refrigeration fan is controlled to increase the speed. Since enough liquid refrigerant has been accumulated in the early stage, the heat exchange effect of the evaporator is good. When the fan speed increases, the instantaneous power of the compressor will not increase too much.

[0062] In this embodiment, when only the freezer compartment has a cooling request, the refrigeration damper is closed and the freezing fan maintains a low speed first. When there is enough liquid refrigerant in the evaporator, that is, when the evaporator outlet temperature T2 drops to the set value, the freezing fan speed increases to enhance the heat exchange coefficient between the air and the evaporator and strengthen the heat exchange. Although the gas-liquid two-phase area is reduced, the total cooling capacity is increased, so that the temperature of the freezer compartment meets the cooling demand more quickly.

[0063] In this embodiment, before controlling the refrigeration fan to increase from the first speed to the second speed, the method also includes: detecting the ambient temperature of the refrigerator; obtaining the first speed and the second speed matching the ambient temperature, wherein the first speed and the second speed are both positively correlated with the ambient temperature.

[0064] In this embodiment, the ambient temperature Ta of the refrigerator is detected, and the first speed S1 and the second speed S2 of the refrigeration fan are matched according to the ambient temperature. Since the higher the ambient temperature, the higher the heat load of the refrigerator, a higher speed is required to meet the refrigeration demand. Therefore, the higher the ambient temperature, the higher the speed of the refrigeration fan, that is, the first speed and the second speed are positively correlated with the ambient temperature, as shown in Table 1 below:

[0065]

[0066] In another implementation of this embodiment, when it is detected that there is a refrigeration request in both the freezer compartment and the refrigerator compartment, the compressor is controlled to be turned on and controlled to run at a third speed C1, and the refrigerator damper is turned on. When the refrigerator damper is turned on, the coldness of the freezer compartment is diffused to the refrigerator compartment through the refrigerator damper; the first surface temperature is read, and the first surface temperature is the surface temperature of the middle section of the evaporator; it is determined whether the first surface temperature is lower than a first preset threshold; if the first surface temperature is lower than the first preset threshold, the refrigeration fan is controlled to be turned on and controlled to run at a first speed S1. In this implementation, the speed of the compressor is further linked. When there is a refrigeration request in both the refrigerator compartment and the freezer compartment, the compressor runs at a lower speed (third speed C1) to meet the cooling of the refrigerator compartment, thereby further reducing the power of the compressor.

[0067] When it is detected that only the freezer compartment has a refrigeration request, the compressor is controlled to be turned on and controlled to run at the third speed C1, the refrigeration damper is closed, and the refrigeration fan runs at the first speed S1; the second surface temperature is read, and the second surface temperature is the surface temperature of the evaporator outlet; it is determined whether the second surface temperature is lower than the second preset threshold; if the second surface temperature is lower than the second preset threshold, the refrigeration fan is controlled to increase from the first speed S1 to the second speed S2, and the compressor is controlled to increase from the third speed C1 to the fourth speed C2. In this embodiment, when only the freezer compartment has a refrigeration request, the refrigeration damper is closed, and the refrigeration fan and the compressor are maintained at a low speed first. When there is enough liquid refrigerant in the evaporator, the speeds of the refrigeration fan and the compressor are increased, so that the temperature of the freezer compartment meets the refrigeration demand more quickly.

[0068] Reference Figure 2 ,During the stable operation of the refrigeration system, when there is no refrigeration request in the refrigeration and freezing compartments, the compressor and refrigeration fan will stop and the refrigeration damper will be closed.

[0069] 1. When there are refrigeration requests for both refrigeration and freezing, the refrigeration damper and compressor are turned on, and the freezing fan remains in the stopped state. Since there is no forced flow of air in the box, the compressor operating power is reduced. When the temperature T1 of the middle section of the evaporator drops to the set value, some liquid refrigerant accumulates in the evaporator. At this time, the freezing fan is turned on and maintained at a low speed S1;

[0070] 2. When only the refrigeration unit has a cooling request, the compressor remains in the stopped state, the refrigeration damper is opened, and the refrigeration fan remains in the stopped state;

[0071] 3. When there is no refrigeration request for either refrigeration or freezing, the refrigeration damper is closed, and the compressor and refrigeration fan are shut down;

[0072] 4. When only the freezing stage has a cooling request, the refrigeration damper is closed, the compressor is turned on, and the freezing fan maintains a low speed S1 operating state until the evaporator outlet temperature T2 drops to the set value. At this time, the liquid refrigerant accumulated in the evaporator is sufficient, and the freezing fan speed increases to S2. Since sufficient liquid refrigerant has been accumulated in the early stage, when the fan speed increases, the instantaneous power of the compressor will not increase too much.

[0073] Reference Figure 3 Compared with the traditional control, the linkage control of the linked refrigeration fan in this embodiment has a significantly lower power than the traditional control in the process from refrigeration request to no refrigeration request in refrigeration and / or freezing. This embodiment uses linkage control to intelligently adjust the speed of the refrigeration fan, which significantly reduces power consumption.
