The present application provides an air conditioner and a control method thereof. The air conditioner includes: a main body defining an appearance; an indoor heat exchanger disposed in the main body; a plurality of branch pipes guiding refrigerant introduced into the indoor heat exchanger; a circulation pipe connected to the plurality of branch pipes to guiding refrigerant; a bypass pipe connecting a part of the plurality of branch pipes to the circulation pipe; and a branch pipe valve disposed in the part of the plurality of branch pipes to regulate inflow into the plurality of branch pipes. The flow of refrigerant in the part of the branch pipe. The portion of the plurality of branch tubes has a smaller diameter than each remaining branch tube. In the cooling mode, refrigerant is introduced from the circulation pipe into the indoor heat exchanger through the part of the plurality of branch pipes. In a heating mode, refrigerant is discharged from the indoor heat exchanger into the circulation pipe through a bypass pipe.
Description
technical field [0001] The present disclosure relates to an air conditioner and a control method thereof. Background technique [0002] An air conditioner is a cooling / heating system that improves indoor space by repeatedly performing a series of operations including taking in indoor air, exchanging heat between low-temperature refrigerant and drawn in indoor air, and discharging the heat-exchanged air into the indoor space. Cooling is performed, or the indoor space is heated by conversely repeating the above-mentioned operation for cooling. Such an air conditioner has a series of cycles consisting of a compressor, a condenser, an expansion valve, and an evaporator. [0003] Air conditioners can be mainly classified into a split type air conditioner in which an indoor unit and an outdoor unit are installed separately, and a package type air conditioner in which the indoor unit and the outdoor unit are integrated. In recent years, considering the installation space and nois...
