description When a refrigeration device in which CO 2 is used as a refrigerant is to be charged with a refrigerant, the time required for charging and the time that elapses after charging until operation can recommence can be reduced. A refrigerant charging method for an air conditioning device (10) in which carbon dioxide is used as a refrigerant comprises a connecting step and a refrigerant charging step. In the connecting step, a cylinder (81) containing the refrigerant is connected to a space in the air conditioning device 10 intended to be charged by the refrigerant, a heater (83) being interposed therebetween. In the refrigerant charging step, the refrigerant is moved to the intended charging space from the cylinder (81), via the heater (83). In the refrigerant charging step, further, the refrigerant that has exited the cylinder (81) is heated by the heater (83) so that a specific enthalpy of the refrigerant when it enters the intended charging space will be 430 kJ/kg or higher.
