Abstract
A refrigerant charging method includes installing, cooling, confirming, and moving steps. In the installing step, a refrigeration device is installed on site. In the cooling step, a container is cooled to 31° C. or below using a cooling medium. In the confirming step, it is confirmed that the container has reached 31° C. or below. In the moving step, the refrigerant is moved to the intended charging space from the container upon confirming that the container has reached 31° C. or below via the cooling step. When moving the refrigerant from the container to the intended charging space, first, refrigerant that is in a gas phase within the container is moved into the intended charging space, whereupon refrigerant that is in a liquid phase within the container is moved into the intended charging space.
