Abstract

The purpose of the present invention is to provide an air conditioner with which the compressor discharge temperature can be kept from rising and with which the air conditioning capability of each of a plurality of indoor units can be controlled separately. This air conditioner is made as a multi room air conditioner that constitutes a refrigeration cycle by connecting by using a liquid pipe (121) and a gas pipe (122): an outdoor unit (100) including an outdoor heat exchanger; and a plurality of indoor units (200, 300) each including an indoor heat exchanger (201 301) and an indoor expansion mechanism (203, 303). R32 or a mixed refrigerant including greater than or equal to 70 mass% of R32 is used as the refrigerant that circulates the refrigeration cycle. The air conditioner further comprises a temperature difference detection device that detects the air temperature difference between the inlet side air and the outlet side air of the indoor heat exchanger of each said indoor unit. The air conditioning capability of each said indoor unit is controlled by adjusting the indoor expansion mechanism of each said indoor unit on the basis of the air temperature difference in each said indoor unit as detected by the temperature difference detection device.
