Abstract
A refrigerant charging method is for charging a refrigerant into a refrigeration circuit including a compressor, a condenser, a throttle device, an evaporator, and a first port that is disposed in a high pressure portion of the compressor or in a location downstream of the compressor and upstream of the throttle device. The method includes: connecting, to the first port, a mouth of a container in which the refrigerant including a high boiling point refrigerant in a liquid state and a medium boiling point refrigerant having a boiling point lower than that of the high boiling point refrigerant and in a wet gas state is enclosed; and charging at least a portion of the refrigerant in the container into the refrigeration circuit through the first port from the container in a position such that the mouth faces downward.
