Abstract
An automotive air conditioner using a mixed type coolant of a higher boiling point coolant and a lower boiling point coolant. The air conditioner employs a stacking container connecting to an upper portion of a receiver for introducing a gas phased coolant which contains much of the lower boiling point coolant via a first valve. The stacking container is also connected to a suction side of a compressor via a second valve. The air conditioner becomes a mixing mode when the first valve closes a conduit and the second valve opens a conduit for introducing the lower boiling point coolant into a refrigerant circuit. The cooling ability is increased during the mixing mode. The air conditioner becomes a separating mode when the first valve opens the conduit and the second valve closes the conduit for separating the lower boiling point coolant circulating in the refrigerant circuit and stacking the same in the container. The consuming energy for operating the refrigerant circuit is decreased during the separating mode.
