Variable-frequency refrigerator and control method thereof

Abstract

The invention provides a variable-frequency refrigerator and a control method thereof. The variable-frequency refrigerator comprises a box body and a door body, a chamber is arranged in the box body,a first temperature sensor is used for detecting the ambient temperature; a second temperature sensor is used for detecting the actual temperature of the chamber; a humidity sensor is used for detecting the ambient humidity; and the first temperature sensor, the second temperature sensor, the humidity sensor and the compressor are correspondingly connected with a compressor and a control panel; the refrigerator is in a normal operation state, the control panel is used for acquiring the temperature difference between the actual temperature of the chamber and the preset temperature of the chamber, and the control panel controls the rotating speed of the compressor according to the ambient temperature, the ambient humidity and the temperature difference value.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an inverter refrigerator and a control method for the inverter refrigerator. Background technique [0002] With the popularization of frequency conversion technology, frequency conversion technology is gradually applied in the field of refrigerators. Compared with traditional fixed frequency refrigerators, frequency conversion refrigerators have the advantages of low energy consumption and low noise. Therefore, frequency conversion refrigerators are more and more widely used. [0003] In the inverter refrigerator, the working power of the inverter compressor will vary according to the speed of the compressor, the status of the refrigerator, and the number of items placed in the refrigerator. As the core of the entire refrigerator system, the more stable the working power of the inverter compressor, the better, that is, when the refrigerator is in a relatively stab...

AI Technical Summary

Problems solved by technology

For example, when the ambient temperature is high, the operating power of the inverter compressor of the refrigerator is higher than that of the inverter compressor when the temperature is low to meet the cooling needs of users; when the refrigerator is in a low-temperature environment, although the high operating power of the inverter compressor can meet Cooling requirements, but it will cause higher power consumption of the refrigerator, so the inverter compressor operates at a lower power to meet the cooling needs of users while saving energy and electricity

[0004] At present, the control method of the existing frequency conversion refrigerator mainly controls the speed of the compressor according to the set temperature of the refrigerator compartment. This control method often leads to excessive speed of the compressor, resulting in a large loss of energy consumption, and cannot effectively realize the frequency conversion. The purpose of energy saving of the compressor
