AI Technical Summary

Technical Problem

When adjusting the temperature of the freezer and refrigerator, the single-system refrigerator causes the air with a higher temperature in the refrigerator to circulate for a long time, increasing the heat load and resulting in lower energy efficiency.

Method used

By providing a first temperature sensor in the refrigeration system at the inlet of the evaporator, the controller adjusts the rotation speed of the condensing fan and/or the rotation speed of the compressor according to the rate of change in the inlet temperature to match the output of the refrigeration system with the actual demand of the refrigerator.

Benefits of technology

It realizes efficient operation of the refrigeration system, avoids the compressor and condenser fan for a long time and high power operation, reduces the energy consumption of the refrigerator, and improves energy efficiency.

Abstract

The invention discloses a refrigerator and a control method thereof, relates to the technical field of refrigerators, and aims to solve the problem of low energy efficiency of a single-system refrigerator in the prior art. The refrigerator comprises a refrigerating system, a first temperature sensor and a controller, the refrigerating system comprises a compressor, a condenser, a throttling device and an evaporator which are sequentially communicated through a pipeline to form a refrigerant circulation loop, the refrigerating system further comprises a condensation fan, and the condensation fan is used for blowing air to the condenser; the first temperature sensor is arranged at an inlet of the evaporator and used for detecting the inlet temperature of the evaporator. The controller is connected with the compressor, the condensate fan and the first temperature sensor and is configured to receive the inlet temperature detected by the first temperature sensor and calculate the change rate of the inlet temperature under the condition that the refrigerating system operates; and adjusting the rotating speed of the condensate fan and / or the rotating speed of the compressor according to the change rate. The refrigerator is used for storing food.
