(57) 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).
