Publication number: 20240175613Abstract: A refrigeration cycle device includes a heat exchanger main body, a plurality of flow rate adjusters, and a controller. The heat exchanger main body has a plurality of refrigerant flow paths including a first refrigerant flow path and a second refrigerant flow path. The flow rate adjusters adjust flow rates of a refrigerant flowing through the refrigerant flow paths. The controller adjusts the flow rates of the refrigerant flowing through the refrigerant flow paths by controlling opening degrees of the flow rate adjusters. The controller controls the opening degrees of the flow rate adjusters based on a first value or a second value. The first value is a value representing overall efficiency of the refrigeration cycle. The second value is a value representing overall efficiency of the heat exchanger main body.Type: ApplicationFiled: February 2, 2024Publication date: May 30, 2024Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Takashi MAEDA, Ryuhei KAJI, Tomoki HIROKAWA
