Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
As shown in figure 1, in present embodiment, a kind of accurate control of refrigerator compartment temperature dynamic compensation provided herein Warm method, it comprises the following steps:
Step A:The temperature of refrigerator compartment is detected by compartment temperature sensor, is detected by environment temperature sensor extraneous The temperature of environment;
Step B:Temperature compensation value is drawn according to the design temperature of ambient temperature value and refrigerator compartment;
Step C:The refrigerator compartment temperature measured is subtracted into the actual temperature that temperature compensation value draws refrigerator compartment, it is relatively more real The design temperature of border temperature and refrigerator compartment, and according to the operation of both comparative results control compressor.
