A drying apparatus is disclosed. The drying apparatus comprises: a drum; a compressor for compressing a refrigerant; a first temperature sensor provided at an air discharge port of the drum; a second temperature sensor provided at a refrigerant discharge port of the compressor; and a processor which, when a drying cycle for an object to be dried begins, compares a first temperature sensed by the first temperature sensor with a predetermined threshold temperature so as to obtain an operation frequency of the compressor, and when a second temperature sensed by the second temperature sensor reaches a predetermined first target temperature, adjusts the operation frequency of the compressor on the basis of a third temperature calculated on the basis of the first temperature and the second temperature.

Drying apparatus and method for controlling same

Disclosed herein is an air conditioner. The air conditioner includes an outdoor unit having a compressor, an outdoor heat exchanger, and a flowpath switching valve disposed on a refrigerant flowpath between the compressor and the outdoor heat exchanger, a plurality of indoor units configured to operate in a cooling mode or in a heating mode, a mode controller configured to selectively guide refrigerant received from the outdoor unit to the plurality of indoor units. The mode controller guiding the refrigerant through one or more of: a first refrigerant pipe extending from the flowpath switching valve to the mode control unit, a second refrigerant pipe extending from the flowpath switching valve and diverging to the outdoor heat exchanger, and to the mode control unit, and a third refrigerant pipe extending from the outdoor heat exchanger to the mode controller.

Air conditioner

A heat exchanger that effectively distributes a refrigerant by varying the cross-sectional area of a header and an air conditioner having the same. The heat exchanger includes a plurality of refrigerant tubes disposed spaced apart from each other, a header joined to both ends of each of the refrigerant tubes, at least one baffle to divide the refrigerant tubes into a plurality of mutually adjacent groups and block a longitudinal flow of a refrigerant flowing in the header, each of the groups causing the refrigerant to flow in one direction, and a booster installed to vary a cross-sectional area of the header to uniformly distribute the refrigerant to refrigerant tubes in the same group among the refrigerant tubes. The booster to vary the cross-sectional area of the header may allow a refrigerant flowing through a header to be effectively distributed to the refrigerant tubes.
