Refrigerator temperature control method, controller and refrigerator

Abstract

The invention provides a refrigerator temperature control method, a controller and a refrigerator. The refrigerator temperature control method comprises: acquiring current first temperature values detected by a plurality of temperature sensors distributed in a plurality of partition layers in a refrigerating chamber of the refrigerator; acquiring current actual temperatures in the refrigerating chamber of the refrigerator according to the plurality of first temperature values and preset functions; and controlling the work of a compressor of the refrigerator according to preset target temperatures and the actual temperatures, wherein the preset functions are previously determined according to the number of the partition layers in the refrigerating chamber of the refrigerator and a temperature range of an indoor environment in which the refrigerator is positioned. The refrigerator temperature control method provided by the invention can accurately control the temperature in the refrigerator.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to a refrigerator temperature control method, a controller and a refrigerator. Background technique [0002] Most of the currently used single-system electronic direct-cooling refrigerators use refrigeration sensors to sense the temperature inside the refrigerator to control the start and stop of the compressor, so that the temperature inside the refrigerator can be maintained at a certain level. Since the temperature sensed by the sensor is not the average temperature in the box, although the compressor’s on-off temperature point (the temperature point fed back by the temperature sensor) can be adjusted to ensure that the temperature in the refrigerator meets the requirements, the temperature in the refrigerator often fluctuates greatly. For example, when the set temperature is 5°C, the fluctuation range in the chamber is usually 5±1°C. [0003] For example, in an experiment, th...

Problems solved by technology

[0003] For example, in an experiment, the temperature inside the box was set at 5°C, and the average temperature inside the box obtained through the standard test was 4.5°C. This is because when the load is placed in the refrigerator, if the load itself is at a high temperature and is close to the sensor, the sensor will sense The temperature will be higher, so the refrigeration and refrigeration will be longer, resulting in a lower overall temperature in the box

Similarly, when the temperature of the load itself is low and it is close to the sensor, the temperature sensed by the sensor will be low, so the compressor will stop working for a long time, resulting in a high overall temperature in the box
