Refrigeration cycle apparatus

A refrigeration cycle apparatus comprising:

• a refrigerant circuit including a refrigerant vessel that reserves a refrigerant;
• a flow path switching portion that includes
• a first connecting portion,
• a second connecting portion,
• a third connecting portion connected to the refrigerant vessel, and
• a flow path switching valve that switches between a first state in which the third connecting portion communicates with the first connecting portion and a second state in which the third connecting portion communicates with the second connecting portion;
• and
• a safety valve that includes a fourth connecting portion connected to the first connecting portion or the second connecting portion and releases the refrigerant to outside when a refrigerant pressure in the refrigerant vessel satisfies a predetermined condition,
• wherein at least the fourth connecting portion of the safety valve is made of stainless steel, and
• in the flow path switching portion,
• a potential difference between the first connecting portion and the fourth connecting portion is 0.35 V or less,
• a potential difference between the second connecting portion and the fourth connecting portion is 0.35 V or less,
• an allowable tensile stress of the fourth connecting portion with respect to an allowable tensile stress of the first connecting portion is 3.0 times or less, and
• the allowable tensile stress of the fourth connecting portion with respect to an allowable tensile stress of the second connecting portion is 3.0 times or less.
