  • Patent number: 10495350
    Abstract: An ejector-type refrigeration cycle has a compressor, an ejector module, a discharge capacity control section, and a pressure difference determining section. The ejector module has a body providing a gas-liquid separating space. The pressure difference determining section determines whether a low pressure difference operating condition is met. The low pressure difference operating condition is an operating condition in which a pressure difference obtained by subtracting a low-pressure side refrigerant pressure from a high-pressure side refrigerant pressure a predetermined reference pressure difference or lower. The body is provided with an oil return passage that guides a part of a liquid-phase refrigerant to flow from the gas-liquid separating space to a suction side of the compressor. The discharge capacity control section sets a refrigerant discharge capacity to be a predetermined reference discharge capacity or higher when the low pressure difference operating condition is determined to be met.
