Example 2
Referring to fig. 1, a method for controlling a three-temperature-zone dual-system refrigerator includes:
the current temperature of each compartment is monitored in real time through temperature sensors respectively arranged in the refrigerating chamber, the temperature changing chamber and the freezing chamber, and when the current temperature of a certain compartment is higher than the set starting temperature, the refrigerating system is controlled to refrigerate the corresponding compartment until the corresponding compartment reaches the set shutdown temperature;
when the set temperature of the temperature-varying chamber is lower than or equal to minus 10 ℃, the compressor is controlled to start after the real-time temperature of the temperature-varying chamber is higher than the set starting point temperature, and when the set temperature of the temperature-varying chamber is higher than minus 10 ℃, the compressor is not controlled to start by the temperature-varying chamber.
When the temperature of the freezing chamber or the refrigerating chamber is higher than the set starting point temperature, the compressor is started;
when the last compartment in the refrigerating compartment, the temperature changing compartment and the freezing compartment reaches the set shutdown temperature and the temperature of the rest compartments does not rise to the set startup temperature, the compressor is shut down.
When the set temperature of the temperature-variable chamber is higher than minus 10 ℃, the refrigeration start-stop of the temperature-variable chamber does not influence the start-stop of a compressor and is completed only by starting a freezing fan and opening a temperature-variable air door;
when the set temperature of the temperature-varying chamber is lower than or equal to minus 10 ℃, the temperature-varying chamber requires the compressor to be started simultaneously when the compressor is started for refrigeration, and the refrigeration requirement of the temperature-varying chamber is completed by matching with the opening of the refrigeration air door and the starting of the refrigeration fan.
Example 3
With reference to fig. 1, the refrigeration control method in the refrigeration compartment in embodiment 1 or embodiment 2 described above, when refrigeration is required, is:

a2, if the freezing chamber needs to be refrigerated at this time, the temperature-changing chamber does not need to be refrigerated, the freezing fan is not started, and the temperature-changing air door in the refrigerator is closed;
a3, if the temperature-changing chamber needs to be refrigerated at the moment, opening a freezing fan and a temperature-changing air door.
Example 4
With reference to fig. 1, the refrigerating chamber in embodiment 1 or embodiment 2 does not require refrigeration, and the refrigeration control method when the freezing chamber requires refrigeration is as follows:
b1, opening the freezing channel only by the electromagnetic valve in the refrigerator;
and B2, starting a freezing fan in the refrigerator.
When the refrigerating chamber does not need to be refrigerated, the freezing chamber needs to be refrigerated, and the temperature changing chamber needs to be refrigerated, the temperature changing air door is opened.
Example 5
Referring to fig. 1, the control method of the three-temperature-zone two-system refrigerator is applied to the three-temperature-zone two-system refrigerator, and after the refrigerator is powered on and a temperature control system in the refrigerator works, temperature sensors arranged in the refrigerating chamber, the temperature-changing chamber and the freezing chamber monitor the temperature in each chamber in real time.
The temperature-changing chamber and the refrigerating chamber have the same refrigeration priority.
When the temperature of the temperature-changing chamber is higher than the set temperature starting point of the temperature-changing chamber, the freezing fan is started, the temperature-changing air door is opened, and the temperature-changing air door is closed until the temperature of the temperature-changing chamber is reduced to the temperature of the stopping point.
The temperature-changing chamber switches the refrigeration mode according to the set temperature of the chamber.
When the set temperature of the temperature-changing chamber is higher than minus 10 ℃, the start and stop of the temperature-changing chamber do not influence the start and stop of the compressor, namely, after the temperature of the temperature-changing chamber is higher than the set start point, the temperature-changing air door is opened, the refrigerating fan is opened, and until the temperature of the temperature-changing chamber is lower than or equal to the set stop point, the temperature-changing air door is closed.

When the set temperature of the temperature-changing chamber is not higher than-10 ℃, namely less than or equal to-10 ℃, the start and stop of the compressor can be controlled by the start and stop of the temperature-changing chamber. Namely, when the temperature of the temperature changing chamber is higher than a set starting point, the temperature changing air door is opened, the freezing fan is opened, the compressor is started, and the temperature changing air door is closed until the temperature of the temperature changing chamber is lower than or equal to a set stopping point, and the freezing fan and the compressor selectively run or stop according to the starting and stopping states of the freezing chamber.
When the temperature of the refrigerating chamber is higher than the set temperature starting point of the refrigerating chamber, the compressor is started, the electromagnetic valve opens the refrigerating and freezing two refrigerant channels to refrigerate the refrigerating chamber, the refrigerating fan is closed after the temperature of the refrigerating chamber is lower than or equal to the set temperature stopping point of the refrigerating chamber, the electromagnetic valve closes the refrigerating channel, and the freezing channel is opened only.
In the refrigerating process of the refrigerating chamber, if the temperature-changing chamber requires refrigeration, the freezing fan is started, and if the single refrigerating chamber requires refrigeration, the freezing fan needs to be started again to refrigerate the refrigerating chamber after the refrigerating chamber finishes refrigeration.
When the temperature of the freezing chamber is higher than the set temperature starting point of the freezing chamber, the compressor is started, meanwhile, the electromagnetic valve independently opens the freezing channel to refrigerate the freezing chamber, the freezing fan is closed after the temperature of the freezing chamber is reduced to the set temperature stopping point of the freezing chamber, the electromagnetic valve closes the freezing channel, and the refrigerating channel is opened only.
After the compressor is stopped, the electromagnetic valve is switched to the single-opening refrigeration channel.
