However, during the actual use of the refrigerator, the heat load is in a dynamic change, and the heat dissipation load of the condenser will also change accordingly. In this process, if the speed of the condensing fan is only related to the ambient temperature, the ambient temperature will not change, and the speed will not change. The actual heat dissipation of the condenser cannot follow the dynamic change of the load of the whole machine, which may occur: 1. When the user opens the refrigerator and puts a lot of hot food into the box, the heat load of the refrigerator increases rapidly, and the heat dissipation load of the condenser also increases. The condensing fan still maintains the original speed, resulting in insufficient heat dissipation of the condenser, the refrigerant at the outlet cannot be cooled into a liquid state, the system cannot operate normally, the cooling speed becomes smaller, and the power consumption increases; 2. The user puts the refrigerator in a well-ventilated or In a bad environment, the actual heat transfer of the condenser is very different from the design working condition, which leads to a deviation of the system temperature, the system cannot operate efficiently, and the energy consumption increases

The invention provides a control method of a refrigerator and the refrigerator. The control method of the refrigerator comprises the following steps: acquiring the environment temperature and the temperature at the outlet of a condenser; and adjusting the rotate speed of a condensing fan according to the environment temperature and the difference value between the environment temperature and the temperature at the outlet of the condenser. According to the control method of the refrigerator provided by the invention, the rotate speed of the condensing fan is adjusted jointly according to the environment temperature and the difference value between the environment temperature and the temperature at the outlet of the condenser, so that the actual heat dissipating capacity of the condenser ismatched with the heat load of a system, and therefore, the refrigerator operates efficiently and the power consumption of the refrigerator is reduced.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator control method and the refrigerator. Background technique [0002] The condenser fan speed of existing refrigerators on the market is simply set according to the ambient temperature, that is, when the refrigerator is running, the temperature of the environment is collected through the ambient temperature, and then calculated by the algorithm preset in the program. The speed of the condensing fan out of the refrigerator is only related to the ambient temperature and has nothing to do with others. However, during the actual use of the refrigerator, the heat load is in a dynamic change, and the heat dissipation load of the condenser will also change accordingly. In this process, if the speed of the condensing fan is only related to the ambient temperature, the ambient temperature will not change, and the speed will not change. The actual heat dissipation of the...
