US 2022/0090834 A1 · METHOD OF CONTROLLING REFRIGERATOR

Abstract

A refrigerator includes a temperature sensor provided in a storage space of the refrigerator to detect a temperature; an inverter compressor constituting a freezing cycle for cooling the storage space, the number of rotations being variable by frequency control; and a controller for controlling the operation of the inverter compressor. The controller may variably control the operating frequency of the inverter compressor according to the load of the storage space in order to maintain the storage space at a set temperature, and compare the operating frequency with a stop frequency when a stop signal is input, when the operating frequency is lower than the stop frequency, raise the frequency of the inverter compressor to the stop frequency, and then stop the inverter compressor.

Dependent claims

A method of controlling a refrigerator comprising:

performing a lubrication operation that includes operating a compressor at a first frequency after initiating the compressor;
performing, after the lubrication operation, a load-response operation that includes determining a second frequency of the compressor according to a load of a storage space of the refrigerator, and operating the compressor at the second frequency;
and
performing a stop operation that includes comparing the second frequency with a third frequency when a stop condition occurs, and then increasing a frequency of the compressor to the third frequency and then stopping the compressor when the second frequency is less than the third frequency.
