Abstract
According to the present disclosure, after a load operation is performed by satisfying a start condition of the load operation, the load operation is terminated when a compartment temperature of a storage compartment satisfies a termination condition when a door is opened or when a temperature change in the storage compartment satisfies the termination condition. Accordingly, excessive power consumption during the load operation may be prevented, and thus power consumption may be improved.
Claims7
A control method of a refrigerator, the method comprising:
- a temperature measurement step of measuring a temperature in a storage compartment;
- a door open confirmation step of confirming whether a door is open;
- a start condition determination step of determining whether or not a start condition for a load operation is satisfied based on the temperature in the storage compartment;
- a performing operation step of performing the load operation in response to the start condition of the load operation being satisfied, wherein a temperature in the storage compartment is checked at the start of the load operation and stored;
- a termination condition determination step of determining whether or not a termination condition of the load operation is satisfied based on the temperature in the storage compartment;
- and
- an operation termination step of terminating the load operation in response to the termination condition of the load operation being satisfied,
- wherein the termination condition of the load operation is determined to be satisfied in response to the temperature in the storage compartment checked during the load operation falls lower than the stored temperature in the storage compartment checked at the start of the load operation.
A control method of a refrigerator, the method comprising:
- a temperature measurement step of measuring a temperature in a storage compartment;
- a door open confirmation step of confirming whether a door is open;
- a start condition determination step of determining whether or not a start condition for a load operation is satisfied based on the temperature in the storage compartment;
- a performing operation step of performing the load operation in response to the start condition of the load operation being satisfied,
- wherein, during the load operation, a temperature change amount (ΔT) per unit time of the temperature in the storage compartment is measured in response to the temperature in the storage compartment reaching an upper limit notch temperature (NT+diff) set based on a set notch temperature (NT);
- a termination condition determination step of determining whether or not a termination condition of the load operation is satisfied based on the temperature in the storage compartment,
- wherein the termination condition of the load operation is controlled to be changed according to the temperature change amount (ΔT);
- and
- an operation termination step of terminating the load operation in response to the termination condition of the load operation being satisfied.
