摘要:
The disclosure describes a control device for the air-conditioning device for automobile in which a rolling piston type capacity changeable compressor which can be operated with a single piston cylinder by closure of one of two coaxial cylinders in the compressor by means of an opening and closing valve is used and selection is made as to whether single cylinder or double cylinders should be employed for operation of the compressor depending on a cooling load to be imposed on it.

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 automobile ventilator which is a conventional ventilating device and a conventional air cleaning device combined into one. The ventilator structure has an air blowing passage opening into a passenger room of the vehicle. Through the air blowing passage comes out air blown by an impeller provided at the passage. There are further two passages to guide air to the impeller; one is a ventilation passage communicating outside the vehicle body while the other is a circulation passage opening into the passenger room. A damper is provided between the two passages in hinge fashion to selectively close either one of the two passages. This damper is controlled by manipulating the ignition switch such that the ventilation passage is closed on engine start whereas the circulation passage is closed when the engine is stopped. The impeller is driven alternately by first and second drive circuits. The first drive circuit is placed in an operative condition when the ignition switch is thrown to ON position whereas the second drive circuit is placed in an operative condition when the ignition switch is thrown to OFF position.

A temperature control device for a vehicle cabin comprises a duct which communicatively connects, at least, inside the vehicle cabin and the external atmosphere; a damper provided within the duct and for shutting off flow of air inside and outside the vehicle cabin; drive means for driving the damper to open and close; a fan to produce the air flow within the duct; a fan motor to actuate and drive the fan; detecting means to detect temperature changes within the vehicle cabin; and a power source separately provided from an ordinary power source and for supplying power to the fan motor. A temperature increase within the vehicle cabin above a predetermined temperature is detected by the detecting means, then electric power is supplied to the fan motor from the separately provided power source, and the temperature within the vehicle cabin is controlled in utilization of the duct, in which the damper is in an open state.

There are provided a plurality of groups 14 and 34 which are arranged in an outlet of a main body, and which comprise blowing direction deflecting plates 1, 2 and 3, and 21, 22 and 23; rotational angle setting means 41a and 41b which are provided for the respective groups 14 and 34, and which set rotation angles of the groups 14 and 34; rotational angle limit detection means 42a and 42b for comparing preset limiting rotation angles of the groups 14 and 34 to the set rotation angles; and rotational direction reversing means 43 for reversing the rotational directions of the groups 14 and 34 when at least one of the groups 14 and 34 has reached the limiting rotation angle. Blowing direction of conditioned air can be adjusted while constantly keeping an arbitrary phase difference in blowing direction between the groups.
