Abstract: Provided is a refrigerant cycle of an air conditioner for vehicles, and more particularly, a refrigerant cycle of an air conditioner for vehicles having a first evaporating unit and a second evaporating unit disposed upstream and downstream in a direction in which air blown from a single blower flows to control an amount of the refrigerant supplied to each evaporating unit, thereby making it possible to obtain optimal radiating performance (cooling performance) and cooling efficiency (COP) through the design of the optimal refrigerant flow ratio depending on the cooling load.

Abstract: Disclosed is an apparatus and a method for controlling a driving of a fan motor for a refrigerator. In a normal driving mode that a temperature of the inside of the refrigerator is higher than a predetermined temperature, the fan motor is driven in a normal speed, and in a waiting mode that the temperature of the inside of the refrigerator is lower than the predetermined temperature, the fan motor is driven in a driving speed very lower than that of the normal driving mode, without stopping of the fan motor, accordingly it is capable of preventing moisture introduced into the fan motor from being frozen, thereby preventing the fan motor from being locked.
