  • Publication number: 20250164168
    Abstract: A heat source unit includes a controller configured to control the subcooling-side decompression valve according to a degree of subcooling of a refrigerant flowing out of the first flow path of the subcooling heat exchanger. Under a condition that the opening degree of a subcooling-side decompression valve is equal to or greater than a predetermined opening degree, the controller determines that there is a shortage of a refrigerant in the refrigerant circuit.
