Abstract

An air conditioner is provided that may include an outdoor unit provided with a compressor; a plurality of indoor units connected to the outdoor unit, each having an indoor heat exchanger, and each disposed in a different space; a low pressure pipe that connects the indoor heat exchanger and the compressor and in which low pressure gaseous refrigerant flows; a switching device provided with a low pressure valve disposed between the indoor heat exchanger and the low pressure pipe; an indoor temperature sensor that measures a temperature of a space in which an indoor unit of the respective indoor unit is disposed; and a controller that is electrically connected to the indoor temperature sensor and adjusts an opening degree of the low pressure valve. The controller may adjust the opening degree of the low pressure valve based on a difference between a value measured by the indoor temperature sensor and a previously input set temperature. By increasing an evaporation pressure in the indoor unit, noise from the air conditioner may be suppressed or prevented and comfort improved.
