An air-conditioner for an automobile is disclosed which is provided with a compressor adapted to be directly connected to the engine, the compressor being provided with two coaxial compressing cylinders each having a different displacement, whereby the cylinder having the smaller displacement is adapted to be always operated to carry out the dehumidification, while the cylinder having the larger displacement is adapted to be operated only when it is desired to air-condition the compartment by a change in its operation rate through the actuation of such as a slide valve.

An air-conditioner system for dehumidifying and cooling the passenger compartment of an automobile, comprising: a compressor means, a condenser and an evaporator connected in series in a refrigerating circuit; said compressor means having a rotary shaft adapted to be directly connected to the engine

An air-conditioner system for dehumidifying and cooling the passenger compartment of an automobile, comprising: a compressor means, a condenser and an evaporator connected in series in a refrigerating circuit; said compressor means having a rotary shaft adapted to be directly connected to the engine of the automobile for being constantly driven thereby, having one large and one small displacement compressing element each having a different refrigerant compressing capacity, the compressing capacity of said small displacement compressing element being just sufficient for providing sufficient refrigerant for dehumidifying the passenger compartment, and having refrigerant intake means for the respective large and small displacement compressing elements and a common refrigerant discharge connected to said condenser; a refrigerant flow control valve means in said refrigerant intake means for the large displacement compressing element for controlling the amount of refrigerant sucked into said large displacement compressing element for causing the large displacement compressing element to compress a predetermined amount of refrigerant over a period of time, the intake to said small displacement compressing element being unvalved; and temperature setting control means connected to said refrigerant flow control valve means for controlling said refrigerant flow control valve means to provide an amount of refrigerant to said large displacement compressing element sufficient for cooling the passenger compartment to the set temperature.
