An air conditioner of present invention comprises a housing having an outer panel forming the exterior and an opening formed on the outer panel, a heat exchanger configured to exchange heat with air flowing into the housing, and a door unit configured to open or close the opening by moving forward or backward from the opening through which the heat exchanged air is discharged. Wherein the door unit comprises a door blade configured to open or close the opening, a door operating part configured to move the door blade forward or backward, and a controller configured to control the air discharged from the opening to be moved forward from the opening in a straight line or to be discharged radially from the opening by controlling a distance between the door blade and the opening.

Air conditioner

A method of operating a controller that controls an operation of a semiconductor memory device including a meta area, a normal area, and a state area, includes sensing a turn-on of a memory system including the controller, checking a last state flag among at least one or more state flags stored in the state area, and determining whether to perform a reclaim operation on meta data stored in the meta area based on the checked state flag.

Controller and method of operating under sudden power interruption

An air conditioner includes a housing, a heat exchanger arranged to exchange heat with air flowing into the housing, a blower fan arranged inside the housing for discharging air that has exchanged heat with the heat exchanger to the outside and a discharging plate having an opening formed to discharge air blown from the blower fan out of the housing, and a plurality of discharging holes formed to discharge air to surroundings of the opening, wherein the discharging plate is arranged to discharge the air that has exchanged heat by the heat exchanger out of the housing, and wherein the discharging plate is made of metal. By such configuration, air conditioner increase user satisfaction.

An air conditioner according to the present disclosure includes a housing provided with an outer panel forming an appearance, and an opening formed in the outer panel; a heat exchanger configured to exchange heat with air introduced to the inside of the housing; a first discharge portion connected to the opening to discharge heat-exchanged air to the outside; a second discharge portion disposed in a lower side of the first discharge portion in the outer panel to discharge the heat-exchanged air; and a blowing fan disposed inside of the housing to move air, which is heat-exchanged by the heat exchanger, in a direction of the second discharge portion.

A particle sensing device and an air conditioner including a sensor has a sensing path through which air passes, a flow path housing which accommodates the sensor and guides air, and a flow path switching device to all air suctioned from the outside is guided to the sensing path, or some of the air suctioned from the outside and moving flows back in an obliquely upward direction and flows into the sensing path.

Particle sensing device and air conditioner including the same

A data storage device capable of improving operation performance by optimizing internal operations is disclosed. The operation method of the data storage device includes grouping memory blocks based on the number of valid pages included in each of the memory blocks; and determining whether to perform a merging process on the groups of memory blocks based on a merging determination value.

Data storage device performing merging process on groups of memory blocks and operation method thereof

A storage device is provided which includes a nonvolatile memory device configured to store a plurality of reference data, a memory configured to store a hash manage table used to manage a plurality of reference hash keys of each of the plurality of reference data, a hash key generator configured to generate a plurality of hash keys based on write requested data, and a memory controller configured to compare the plurality of hash keys and reference hash keys of each reference data to determine whether to store the write requested data in the nonvolatile memory device. The memory controller selects one of the plurality of reference data according to a similarity between the plurality of hash keys and the plurality of reference hash keys of each reference data and stores the write requested data and the selected reference data in the nonvolatile memory device to refer to each other.

Storage device that performs a de-duplication operation, and method of operating the same
