Abstract
A refrigeration apparatus uses R32 as refrigerant, and includes a compressor, a condenser, an expansion mechanism, an evaporator, a branch flow channel branching from a main refrigerant channel joining the condenser and the evaporator, a first opening adjustable valve disposed along the branch flow channel, an injection heat exchanger, a first injection channel, a refrigerant storage tank disposed along the main refrigerant channel, and a second injection channel. The injection heat exchanger exchanges heat between refrigerant in the main refrigerant channel and refrigerant passing through the first opening adjustable valve. The first injection channel guides refrigerant that flows in the branch flow channel and that exits from the injection heat exchanger to the compressor or the suction passage. The second injection channel guides a gas component of refrigerant accumulated inside the refrigerant storage tank to the compressor or the suction passage.
