The freezer still includes: two position sensors 110, one position sensor 110 and a left condenser 1082 are correspondingly arranged on the outer wall of the left side of the box body, and the other position sensor 110 and a right condenser 1084 are correspondingly arranged on the outer wall of the right side of the box body; three short-circuit loops 114, each short-circuit loop 114 is respectively connected with the outer condenser 104 and each inner condenser in parallel, and each short-circuit loop 114 is provided with a control valve 116 for controlling the short circuit of the outer condenser 104 and each inner condenser; the signal transceiver is arranged in the box body and used for receiving the control instruction and sending out a corresponding control signal according to the control instruction; and a microcontroller electrically connected to the signal receiver and each control valve 116, wherein the microcontroller controls the corresponding control valve 116 to open or close in response to the control signal, and when the control command is a noise reduction command, the microcontroller turns on the short circuit 114 of the outer condenser 104 in response to the noise reduction signal corresponding to the noise reduction command.
In the present embodiment, the condenser 104 outside the refrigerator 10 is located at the opposite side of the door of the refrigerator 10, and the control valve 116 is a three-way valve.
In this embodiment, in the refrigerator 10, the refrigerant transfers heat to the outside in the outer condenser 104 and the inner condenser set 108, and flows back to the evaporator set 106, the refrigerant absorbs heat from the inside of the refrigerator 10 in the evaporator set 106, evaporates from a liquid state to a gaseous state, and then enters the compressor 102 through the return air inlet pipeline of the compressor 102, the refrigerant is compressed into a high-temperature and high-pressure liquid in the compressor 102, and flows to the outer condenser 104 and the inner condenser set 108 in sequence through the exhaust air outlet pipeline of the compressor 102, and finally transfers heat to the outside of the refrigerator 10, so as to circulate, thereby achieving refrigeration of the refrigerator 10. Specifically, the outer condenser 104 is directly disposed on the outer wall of the refrigerator 10, so that the refrigerant can directly transfer heat to the outside of the refrigerator 10 through the outer condenser 104, and the heat exchange efficiency is high; when the refrigerant exchanges heat through the inner condenser set 108, the heat is transferred to the outside of the refrigerator 10 through the left condenser 1082, the right condenser 1084 and the refrigerator body of the refrigerator 10 in sequence, and the inner condenser set 108 is arranged inside the refrigerator 10, so that when the inner condenser set 108 works, the noise is low, and the refrigeration process of the refrigerator 10 is quieter. The refrigerant flowing out of the compressor 102 sequentially flows through the outer condenser 104, the left condenser 1082 and the right condenser 1084, and then flows through the capillary tube 112, and the flow velocity of the refrigerant flowing out of the inner condenser set 108 can be reduced by the capillary tube, the pressure of the refrigerant in the pipeline can be reduced, the boiling point of the refrigerant can be reduced, the evaporation of the refrigerant after the refrigerant enters the evaporator set 106 can be facilitated, and the heat exchange of the refrigerant in the evaporator set 106 can be further promoted. After flowing through the capillary tube 112, the refrigerant first passes through the freezing evaporator 1062, and at this time, the temperature of the refrigerant is the lowest, so that the refrigerant can be vaporized and absorb much heat in the freezing evaporator 1062, so that the temperature of the portion of the refrigerator 10 corresponding to the freezing evaporator 1062 is lower, and the refrigeration requirement of food is met, after the refrigerant absorbs heat in the freezing evaporator 1062, the refrigerant flows into the refrigerating evaporator 1064, and the refrigerant is continuously vaporized and absorbs heat in the refrigerating evaporator 1064, which can be understood that the heat exchange efficiency of the refrigerant in the refrigerating evaporator 1064 is lower than that of the refrigerant in the freezing evaporator 1062. The temperature of the part of the refrigerator 10 corresponding to the refrigeration evaporator 1064 is reduced, so that the refrigeration requirement of food is met. The refrigerant then flows into the compressor 102 through the return line of the compressor 102 and enters the next refrigeration cycle.

step S202, obtaining the distance between at least one side wall of the refrigerator body of the refrigerator 10, which is provided with the internal condenser, and a corresponding obstacle;
step S204, respectively judging whether each distance is greater than a preset distance, and generating at least one judgment result;
step S206, determining the internal condensers with the distance larger than the preset distance;
step S208, conducting the short-circuit loop 114 of the internal condenser with the distance larger than the preset distance;
step S210, judging whether the short-circuit loops 114 of all the inner condensers are conducted or not, and generating a first judgment result;
if the first determination result is yes, the process proceeds to step S212, where the short-circuit loop 114 of the outer condenser 104 is disconnected;
step S214, determining whether all the short-circuit loops 114 of the inner condensers are disconnected, and generating a second determination result;
if the second determination result is yes, the process proceeds to step S216 to turn on the short-circuit 114 of the outer condenser 104;

Step S210, judging whether the short-circuit loops 114 of all the inner condensers are conducted or not, and generating a first judgment result; if the first determination result is yes, then all the internal condenser short circuits 114 are turned on, i.e., all the internal condensers stop operating, then the process goes to step S212, where the external condenser 104 is turned off, and the external condenser 104 operates to meet the cooling requirement of the refrigerator 10. Step S214, determining whether all the short-circuit loops 114 of the inner condensers are disconnected, and generating a second determination result; if the second determination result is that all the short-circuit loops 114 of the inner condensers are turned off, that is, all the inner condensers are operated, the process proceeds to step S216, and the short-circuit loops 114 of the outer condensers 104 are turned on to stop the operation of the outer condensers 104, so that the refrigerator 10 can meet the cooling requirement, reduce the noise generated during the operation of the refrigerator 10, and make the operation of the refrigerator 10 more quiet. If the second determination result is negative, the internal condensers partially operate, that is, only one internal condenser operates, the process proceeds to step S218, the short circuit 114 of the external condenser is disconnected, one internal condenser and the external condenser 104 operate simultaneously, and after one internal condenser and the external condenser 104 operate for a period of time, the temperature inside the refrigerator 10 meets the requirements of refrigeration and freezing, and the short circuit 114 of the external condenser 104 is turned on, so that the external condenser 104 stops operating to eliminate the noise generated when the external condenser 104 operates.
