Refrigeration cycle apparatus

A refrigeration cycle apparatus comprising:

• a refrigerant circuit having a compressor, a cooling-heating switching mechanism, a condenser, a refrigerant expansion mechanism, and an evaporator;
• and
• refrigerant circulating through the refrigerant circuit in order of the compressor, the cooling-heating switching mechanism, the condenser, the refrigerant expansion mechanism, the evaporator, and the cooling-heating switching mechanism,
• the compressor having an inlet and an outlet,
• the refrigerant expansion mechanism being configured to open and close the refrigerant circuit,
• the cooling-heating switching mechanism having a multi-way valve,
• the multi-way valve being configured to
• switch to connect the outlet of the compressor to one of the condenser and the evaporator,
• switch to connect the inlet of the compressor to one of the condenser and the evaporator, and
• open and close the refrigerant circuit connected to one of the outlet and the inlet of the compressor,
• during stop of the compressor,
• the refrigerant expansion mechanism being configured to close the refrigerant circuit, and
• the multi-way valve being configured to connect one of the outlet and the inlet of the compressor to the evaporator, and being configured to close the refrigerant circuit connected to the other of the outlet and the inlet of the compressor,
• wherein
• the multi-way valve comprises
• a case having a circular internal space, and a first connection port, a second connection port, a third connection port, a fourth connection port, and a fifth connection port communicating with the internal space, and
• a valve arranged in the internal space of the case and having a first internal flow path and a second internal flow path, the first internal flow path allowing two of the first connection port, the second connection port, the third connection port, the fourth connection port, and the fifth connection port to communicate with each other, the second internal flow path allowing the other two connection ports to communicate with each other, the valve being rotatable about an axial direction, and
• the valve is configured to rotate about the axial direction, thereby switching to allow two of the first connection port, the second connection port, the third connection port, the fourth connection port, and the fifth connection port to selectively communicate with each other by each of the first internal flow path and the second internal flow path, and close the remaining one connection port.
