Problems solved by technology

During the initial process of steady-state refrigeration of the refrigerator, the compressor will rotate at too high speed, resulting in high condensation temperature and low cooling efficiency. At the same time, the high speed will cause the compressor parts to be easily damaged. In addition, the large cooling capacity will cause the refrigerator to consume more energy. Big

Abstract

The invention provides a control method for an inverter refrigerator. The control method comprises the steps: the environment temperature and the environment humidity of an area where the inverter refrigerator is located are obtained; the temperature of a chamber in the inverter refrigerator is obtained, and the temperature difference between the temperature of the chamber and the set temperatureof the chamber is calculated; the compressor rotating speed corresponding to the environment temperature, the environment humidity and the temperature difference is determined according to a preset mapping relationship, wherein the mapping relationship specifies rotating speed values corresponding to an environment temperature numerical range, an environment humidity numerical range and a temperature difference numerical range; and the compressor of the inverter refrigerator is controlled to operate according to the determined rotating speed of the compressor. The invention further provides arefrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigeration and freezing devices, in particular to a refrigerator and a control method thereof. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. The commonly used refrigeration system of a refrigerator is a compression refrigeration system, in which the compressor acts as the power of the refrigeration cycle and is driven by an electric motor to rotate continuously to compress the refrigerant. The variable frequency compressor is a compressor that can change the output energy by adjusting the speed of the compressor within a certain range through a control method or means relative to the compressor with a constant speed. Some refrigerators are equipped with a dry space in the refrigerated compartment. Since it is difficult to ach...
