Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

In the prior art, the temperature of a freezing chamber of a refrigerator cannot be independently controlled, and when the ambient temperature fluctuates within 10-38 ℃, the ratio of refrigerating heat leakage change to freezing heat leakage change is large, namely R = Q refrigerating heat leakage/Q freezing heat leakage, and R low ring temperature is less than R high ring temperature. The refrigerator generally matches the size of a refrigeration and freezing evaporator according to the environmental temperature of 25 ℃ for considering the design requirements of high and low environmental temperatures, and the conventional refrigeration evaporator design method has the defects that the low environmental temperature is below 20 ℃, the temperature of a refrigeration chamber is easy to be lower (deviating from the refrigeration characteristic temperature of 4 ℃ required by the standard of GB8059-2016 household and similar refrigeration appliances), and the temperature of a freezing chamber is easy to be higher (deviating from the refrigeration characteristic temperature of-18 ℃ required by the standard of GB8059-2016 household and similar refrigeration appliances). The temperature of the refrigerating chamber is easy to be higher than 30 ℃ at high ambient temperature (deviating from the refrigerating 4 ℃ characteristic temperature required by the GB8059-2016 household and similar purpose refrigerating appliance standard), and the temperature of the freezing chamber is easy to be lower than a lot (deviating from the freezing-18 ℃ characteristic temperature required by the GB8059-2016 household and similar purpose refrigerating appliance standard). The conventional approach to solve such problems is to add a low temperature compensation heater to the inner liner of the refrigerator, but this approach cannot solve the problems of low temperature of the high ambient temperature freezer, high ambient temperature refrigerator, and low freezer, and also increases the power consumption. Therefore, in view of the above problems, the present application provides the following embodiments.

When the ambient temperature outside the refrigerator is high, the amount of refrigerant in the refrigeration system of the refrigerator that exists in the condenser is reduced, the total amount of refrigerant is not changed, the amount of refrigerant reaching the refrigerating evaporator in the pipeline is increased in response, and the surplus refrigerant is stored in the liquid accumulator 45. In this embodiment, the liquid reservoir can adjust the amount of refrigerant in the refrigeration evaporator pipeline at different ambient temperatures to improve the refrigeration strength of the refrigerating chamber at a high ambient temperature and reduce the refrigeration strength of the refrigerating chamber at a low ambient temperature, thereby ensuring that the temperatures of the refrigerating chamber and the freezing chamber are not too low or too high under different ambient temperatures. In this embodiment, the accumulator 45 can ensure that the refrigerant distribution amount in the refrigerating chamber evaporator pipe is different at different ambient temperatures.
