Example one
The embodiment provides a refrigerator power consumption testing and controlling method, which can enable the actual temperature of each chamber of a refrigerator to be close to the respective characteristic temperature in the power consumption testing process, so that the lowest power consumption of the refrigerator can be obtained through testing, and the testing period is short. Fig. 1 is a flowchart of a method for testing and controlling power consumption of a refrigerator according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:

And S103, controlling the refrigerator to operate according to the adjusted temperature control parameters of each chamber until the power consumption test is finished.
The characteristic temperature is the maximum temperature requirement that the compartment must satisfy in the power consumption test, and the characteristic temperature of each compartment in the refrigerator can be set for the integral average value of the temperature of the fixed point in the compartment. The preset range is related to the characteristic temperature of the compartment, and the compartment temperature is in the preset range and represents that the compartment temperature is close to the characteristic temperature. The temperature control parameter may also include a start-up point temperature that varies with a set temperature. The temperature at the start-up point changes, and the temperature at the stop point also changes. Specifically, the cyclic judgment and adjustment can be performed at certain time intervals so that the actual temperature of the compartment approaches to the characteristic temperature of the compartment.

The set temperature can be set as required. The refrigerator power consumption test is to test the minimum power consumption required to bring the actual temperature of the compartment close to the characteristic temperature. In the process of testing the power consumption of the refrigerator, the actual temperature of each compartment is changed by adjusting the set temperature and/or the shutdown point temperature of the compartment in the process of testing the power consumption of the refrigerator, and finally the actual temperature of each compartment is close to the respective characteristic temperature, so that the lowest power consumption can be accurately tested.
In the power consumption testing process, the temperature control parameters of the compartments are adjusted according to the actual temperature of the compartments and the characteristic temperature of the compartments until the actual temperature of the compartments is within the preset range, and then the refrigerator is controlled to operate according to the adjusted temperature control parameters of the compartments until the power consumption testing is finished.

The actual temperature of the compartment is greater than or equal to T n -b and equal to or less than T n And the actual temperature of the compartment is in a preset range, and the temperature control parameter of the compartment does not need to be adjusted any more. If the actual temperature of a certain chamber is judged to be more than or equal to T for the first time in the power consumption testing process n -b and equal to or less than T n No adjustment of the temperature control parameters of the compartment is necessary.

Further, adjusting the set temperature of the compartment includes: calculating a difference between a characteristic temperature of the compartment and an actual temperature of the compartment; calculating the sum of the current set temperature of the chamber and the difference value to obtain the new set temperature of the chamber; and returning to the step of acquiring the actual temperature of the chamber after the operation is carried out for the preset time according to the new set temperature of the chamber. The preset time is the time for ensuring the refrigerator to operate stably, and can be set according to the actual condition of the refrigerator, for example, the preset time is set to be 3 hours.

After the set temperature of the chamber is adjusted, the temperature of the starting point of the chamber is adaptively calculated, so that the chamber can be operated according to the starting and stopping points to control the temperature of the chamber.
In one embodiment, obtaining the actual temperature of the compartment comprises: calculating the integral average temperature of the chamber in a stable operation stage; calculating the temperature variation of the chamber in the defrosting and recovery period; and calculating the average temperature of the chamber according to the integral average temperature, the temperature variation and the defrosting interval, and taking the average temperature as the actual temperature of the chamber.
For example, the temperature of a fixed point in the compartment is acquired in real time by a temperature sensor, and the integral average temperature T of the compartment in a stable operation stage is calculated ss = tvdt, where T represents the instantaneous temperature of the collection; calculating the temperature variation DeltaTh of the chamber in the defrosting and recovery period df ＝t DF ×(T D2F1 -(T D +T F ))/2，T D2F1 Denotes the integrated average temperature, T, over the defrosting and recovery period D Integral average temperature, T, representing the steady-state operating phase before the defrosting and recovery period F Integral average temperature, t, representing the steady-state operating phase after the defrosting and recovery period DF The total duration of the defrosting and recovery period and the stable operation stages before and after the defrosting and recovery period is represented; calculating the average temperature T of the compartment a ＝T ss +ΔTh df /Δt df Taking Ta as the actual temperature of the compartment, Δ t df The defrosting interval is indicated.
