Abstract
Methods and related systems for charging a refrigerant into a climate control system. In an embodiment, the method includes (a) coupling a storage tank to a refrigerant loop of the climate control system through a charging valve; (b) opening and closing the charging valve in a plurality of cycles; and (c) flowing refrigerant from the storage tank to the refrigerant loop through the charging valve when the charging valve is open, during (b). In addition, the method includes (d) determining a detected saturated temperature of the refrigerant within the refrigerant loop after each cycle of the plurality of cycles; and (e) adjusting an amount of time that the charging valve is open during each cycle of the plurality of cycles during (b) as a function of the detected saturated temperature from a previous cycle of the plurality of cycles.
