For easy understanding, the refrigerator and the operation principle according to the embodiment of the present application will be briefly described as follows:
referring to fig. 1, which illustrates a schematic diagram of a refrigerator provided in some embodiments of the present application, as shown in the figure, the refrigerator 1 may include a controller 11, a main condenser 12, an auxiliary condenser 13, a switching valve 14, a condensation preventing pipe 15, a freezing evaporator 16, a refrigerating plate pipe evaporator 17, an air return heat exchange section 18, a capillary tube 19, and a compressor 20. The controller 11 can control operations of the switching valve 14, the compressor 20, and other components.
The refrigerating process of the refrigerator is briefly described as follows:
the compressor 20 compresses the refrigerant from low-temperature low-pressure gas into high-temperature high-pressure gas, the high-temperature high-pressure gas is condensed into medium-temperature high-pressure liquid through the condenser, the medium-temperature high-pressure liquid is converted into low-temperature low-pressure liquid through the capillary tube 19, the low-temperature low-pressure liquid refrigerant enters the freezing evaporator 16 and the refrigerating plate tube evaporator 17, then absorbs heat and evaporates in the freezing evaporator 16 and the refrigerating plate tube evaporator 17 to form low-temperature low-pressure steam, and the low-temperature low-pressure steam is conveyed into the compressor 20 through the air return heat exchange section 18 again to be compressed into high-temperature high-pressure gas, so that the refrigerating cycle is completed. The freezing evaporator 16 is provided in a freezing chamber of the refrigerator, and cools the freezing chamber when the refrigerant absorbs heat. The cold storage plate tube evaporator 17 is provided in a cold storage compartment of the refrigerator, and cools the cold storage compartment when the refrigerant absorbs heat.
In the present embodiment, the condenser is divided into a main condenser 12 and an auxiliary condenser 13, and a switching valve 14 is connected in parallel between the inlet end and the outlet end of the auxiliary condenser 13. The switching valve 14 is an electric switching valve. The switching valve 14 includes a first valve connected to an outlet end of the compressor 20 and an inlet end of the auxiliary condenser 13, and a second valve connected to an outlet end of the compressor 20 and an inlet end of the main condenser 12. Whether the auxiliary condenser 13 is added to the circuit of the refrigerant cycle is controlled by adjusting the on-off states of the first valve and the second valve. Specifically, the first valve is controlled to close while the second valve is controlled to open, and refrigerant flows from the compressor 20 directly to the main condenser 12. The first valve is controlled to be opened while the second valve is controlled to be closed, and the refrigerant flows from the compressor 20 through the auxiliary condenser 13 and the main condenser 12 in sequence.
According to the different switch states of the first valve and the second valve included in the switching valve 14, there are two condensation modes in the embodiment of the present application: firstly, the main condenser 12 carries out the condensation work independently; secondly, the main condenser 12 and the auxiliary condenser 13 carry out condensation work together.
In the embodiment of the application, when the ambient temperature of the refrigerator is higher, such as higher than 14 ℃ or 15 ℃, a condensation mode that the main condenser 12 and the auxiliary condenser 13 carry out condensation work together is adopted. When the environment temperature of the refrigerator is low, such as lower than 14 ℃ or 15 ℃, the refrigerating mode that two condensing modes are alternately carried out is adopted.
In contrast to the condensing mode in which the main condenser 12 and the auxiliary condenser 13 perform the condensing operation together, in the condensing mode in which the main condenser 12 performs the condensing operation alone, the condenser through which the refrigerant flows has only the main condenser 12, the effective length of the condenser through which the refrigerant flows becomes short, the condensing temperature increases, and thus the evaporating temperature also increases accordingly. The cooling speed of the refrigerating chamber is reduced, and for the refrigerator with refrigerating and temperature control, the starting time of the refrigerating chamber can be prolonged, namely the starting time of the compressor 20 is prolonged, so that the starting rate of the compressor 20 is improved, and the temperature of the freezing chamber is indirectly controlled.
In the embodiment of the present application, the starting time of the refrigerating chamber is adjusted by adjusting the operation duration of the two condensing modes, so as to improve the starting rate of the compressor 20. In the embodiment of the present application, for refrigerators of different models, control durations corresponding to two condensing modes in temperature intervals of different environmental temperatures are determined through a large number of tests, and a mapping relationship between the temperature intervals of different environmental temperatures and the control durations of the two condensing modes is written into a control program of the controller 11 of the refrigerator.
For example, the mapping relationship between the temperature intervals of different ambient temperatures and the control periods of the two condensing modes is shown in table 1, and when the ambient temperature is greater than 11 ℃ and less than or equal to 14 ℃, the period during which the refrigerant alone flows through the main condenser 12 is 15min, and the period during which the refrigerant flows through the main condenser 12 and the auxiliary condenser 13 is 15 min. When the ambient temperature is higher than 8 ℃ and lower than or equal to 11 ℃, the time period for the refrigerant to independently flow through the main condenser 12 is 20min, and the time period for the refrigerant to flow through the main condenser 12 and the auxiliary condenser 13 is 10 min. When the ambient temperature is higher than 5 ℃ and lower than or equal to 8 ℃, the time period for the refrigerant to independently flow through the main condenser 12 is 25min, and the time period for the refrigerant to flow through the main condenser 12 and the auxiliary condenser 13 is 5 min. When the ambient temperature is less than or equal to 5 ℃, the time period for the refrigerant to independently flow through the main condenser 12 is 30min, and the time period for the refrigerant to flow through the main condenser 12 and the auxiliary condenser 13 is 0 min.
TABLE 1
After the mapping relationship between the temperature interval and the control durations corresponding to the two condensing modes is written in the controller of the refrigerator, based on the structure of the refrigeration system shown in fig. 1, the on-time rate of the compressor can be controlled by adjusting the on-off state of the switching valve according to the control method provided in the following embodiment based on the mapping relationship in the controller.
The following description of the embodiments can be understood with reference to fig. 1 and the above description.

In the embodiment of the application, the refrigerator is also provided with a temperature sensor, and the ambient temperature of the environment where the refrigerator is located is detected in real time through the temperature sensor. The controller of the refrigerator acquires the ambient temperature of the environment in which the refrigerator is located from the temperature sensor.
Step 102: and acquiring a first control duration and a second control duration corresponding to the ambient temperature according to the fact that the ambient temperature is less than or equal to a preset temperature threshold.
The preset temperature threshold may be 10 ℃ or 14 ℃ or the like. And comparing the ambient temperature of the environment where the refrigerator is located with a preset temperature threshold value, and determining whether the current ambient temperature is less than or equal to the preset temperature threshold value. And if the current environment temperature is determined to be less than or equal to the preset temperature threshold, acquiring a first control duration and a second control duration corresponding to the environment temperature.
Firstly, determining a temperature interval to which the environment temperature belongs; and then acquiring a first control duration and a second control duration corresponding to the temperature interval to which the ambient temperature belongs from the mapping relation between the temperature interval and the control durations of the two condensing modes.
For example, assuming that the mapping table shown in table 1 is stored in the refrigerator controller, and the obtained ambient temperature at which the refrigerator is located is 10 ℃, the temperature interval to which the ambient temperature 10 ℃ belongs is determined to be (8, 11), the first control time length corresponding to the temperature interval (8, 11) is obtained from the mapping table shown in table 1 and is 20min, and the second control time length is 10 min.
Step 103: the switching valve connected between both ends of the auxiliary condenser is alternately controlled by a first control period and a second control period to alternately change the effective length of the condenser through which the refrigerant flows, thereby controlling the on-time rate of the compressor.
The control is switched to the main condenser side by a switching valve connected between both ends of the auxiliary condenser. I.e. the first valve connected to the outlet of the compressor and the inlet of the auxiliary condenser is controlled to be closed and the second valve connected to the outlet of the compressor and the inlet of the main condenser is controlled to be open. As shown in fig. 3, the arrows in fig. 3 indicate the flowing direction of the refrigerant, and the circulation circuit of the refrigerant includes a compressor 20, a main condenser 12, a condensation preventing pipe 15, a capillary tube 19, a return air heat exchange section 18, a freezing evaporator 16 and a refrigerating plate tube evaporator 17. The only condenser through which the refrigerant flows in sequence is the main condenser. The switching valve is kept to be switched to the side of the main condenser for a first control duration, the refrigerant only flows through the main condenser within the first control duration, the auxiliary condenser does not participate in working, the effective length of the condenser through which the refrigerant flows is shortened, so that the condensing temperature and the evaporating temperature are both increased, and the cooling speed of the refrigerating chamber is reduced, so that the starting time of the refrigerating chamber is prolonged, namely the starting time of the compressor is prolonged, the starting rate of the compressor is improved, the temperature of the refrigerating chamber is indirectly controlled, and the temperature of the refrigerating chamber is prevented from being overhigh.
And starting timing when the control switching valve is switched to the main condenser side, if the timing duration is determined to reach the first control duration, determining that the first control duration is over, and controlling the switching valve to be switched to the auxiliary condenser side. I.e. the first valve is controlled to be opened and the second valve is controlled to be closed, and the normal refrigeration is recovered. As shown in fig. 4, arrows in fig. 4 indicate the flowing direction of the refrigerant, and the circulation circuit of the refrigerant includes a compressor 20, an auxiliary condenser 13, a main condenser 12, a condensation preventing pipe 15, a capillary tube 19, an air-return heat exchange section 18, a freezing evaporator 16 and a refrigerating plate-tube evaporator 17. The condenser through which the refrigerant flows includes an auxiliary condenser and a main condenser. The switching valve is kept switched to the auxiliary condenser side for a second control period.
The total duration of the first control duration and the second control duration is a control period, and a specific value of the control period may be flexibly set according to a requirement, for example, the control period may be 20 minutes, half an hour, or an hour, and the embodiment of the present application is not limited. The controller controls the refrigerator to alternately perform condensation work in two condensation modes according to the control period cycle.
In this application embodiment, still through the indoor cold-stored temperature of temperature sensor real-time detection cold-stored room, the controller acquires this cold-stored temperature from temperature sensor to compare this cold-stored temperature and the preset fender position temperature of temperature controller, if confirm that cold-stored temperature is less than or equal to preset fender position temperature, then control the compressor and shut down. And if the refrigerating temperature is determined to be higher than the preset gear temperature, periodically and alternately carrying out condensation work in two condensation modes according to the first control time length and the second control time length in the manner.
When the ambient temperature of the refrigerator is less than or equal to the preset temperature threshold, the load of a refrigerating system of the refrigerator is small, and the cold quantity requirement of the refrigerating chamber is low. And this application embodiment carries out condensation work through two kinds of above-mentioned condensing mode in turn, in first kind condensing mode, the refrigerant only flows through main condenser, the condenser effective length who flows through is short, the condensation temperature can rise, correspondingly evaporation temperature also can rise, the cooling rate of cold-storage room can descend, consequently can prolong the boot time of cold-storage room, thereby improve the rate of operation of compressor, make the cold-storage room temperature can satisfy the demand, need not to improve complete machine rate of operation through the mode that increases the compensation heater in cold-storage room, the energy consumption of refrigerator has been reduced.
If it is determined in step 102 that the ambient temperature of the current refrigerator is greater than the preset temperature threshold, and the heat load of the refrigeration system of the refrigerator is greater at this time, the switching valve is controlled to switch to the auxiliary condenser side, that is, the first valve is controlled to be opened, and the second valve is controlled to be closed, so that the refrigerant flows through the main condenser and the auxiliary condenser, and the refrigerant flows in the direction indicated by the arrow in fig. 4.
