Abstract

An air-conditioning apparatus includes an outdoor unit with a compressor, an outdoor heat exchange, a four-way valve for switching a refrigerant flow passage, and an outdoor flow control valve which controls the flow rate of a liquid refrigerant; and an indoor unit that includes an indoor heat exchanger, and an indoor flow control valve which reduces refrigerant pressure. A refrigerant circuit is formed by connecting the outdoor unit and at least one indoor unit by a pipe. A controller controls a component of the refrigerant circuit, based on the relationship between a first target set temperature used for temperature control of air to be conditioned and a preset second target set temperature.
