The present invention provides a simultaneous cooling and heating type refrigeration cycle apparatus with a simple configuration using outdoor units (20a; 20b) in which a cooling operation and a heating operation can be performed in a switchable manner. There is provided a refrigeration cycle apparatus including: a first and a second outdoor units (20a; 20b), each including a compressor (1), an outdoor heat exchanger (2), a gas connection port (5), and a liquid connection port (6); a plurality of indoor units (21a; 21b; 21c) in which indoor liquid pipes, indoor heat exchangers (30), and indoor gas pipes (32) are connected in order; and a common liquid pipe through which the liquid connection port of each outdoor unit is communicated with the indoor liquid pipes (10a, 10b, 10c) in the plurality of indoor units (21a; 21b; 21c), wherein each of the indoor gas pipes in the respective indoor units (21a; 21b; 21c) is branched into a first gas pipe (11) and a second gas pipe (12), the first gas pipe (11) is connected to the gas connection port (5) of one of the outdoor units (20a; 20b), the second gas pipe (12) is connected to the gas connection port (5) of the other of the outdoor units (20b; 20a), pipe switching units (3), each switching the respective channels of the first gas pipe (11) and the second gas pipe (12) in each of the indoor units (21a; 21 b; 21c), and each of the indoor heat exchangers (30) is communicated with only one of the outdoor units (20a; 20b) by switching the pipe switching units (3).
