| description | An object of the present invention is to provide a refrigeration cycle apparatus that can collect refrigerant inside liquid-side crossover piping when stopped even if liquid-side crossover piping for low-pressure refrigerant is used, enabling the occurrence of problems with pressure tolerance in the liquid-side crossover piping to be suppressed, shortening installation time, and enabling installation costs to be reduced, and that can also make a refrigerant storage tank more compact. The refrigeration cycle apparatus according to the present invention includes: liquid-side connection piping that extends from liquid-side refrigerant piping; gas-side connection piping that extends from gas-side refrigerant piping; a refrigerant storage tank that stores refrigerant, an intake side thereof being connected to the liquid-side connection piping, and a discharge side thereof being connected to the gas-side connection piping; an inlet-side electromagnetic valve that is disposed on the liquid-side connection piping, and that is opened when there is no passage of electric current; an inlet-side check valve that is disposed on the liquid-side connection piping, and that allows the refrigerant to flow only toward the refrigerant storage tank; and a valve apparatus that is disposed on the gas-side connection piping, that is opened during passage of electric current to the inlet-side electromagnetic valve, and that is delayed before being shut off after passage of electric current to the inlet-side electromagnetic valve is stopped. |
