Document Type and Number:
Japanese Patent JP6778884
Kind Code:
B2
Abstract:
A refrigeration cycle apparatus includes an evaporator (21), a turbo compressor (22), a condenser (23), a switching mechanism (28), a first pump (26), a second pump (27), and a controller (30). When the turbo compressor is in a surge state or a choke state, the controller controls the switching mechanism to set a state of interconnection among a first flow passage (24a), a second flow passage (24b), a third flow passage (25a), and a fourth flow passage (25b) to a first connection state. In the first connection state, the first flow passage, the fourth flow passage are connected to each other, and the second flow passage and the third flow passage are connected to each other.
