Embodiment Construction

[0032] Although described here in terms of an air conditioner mounted on an automobile and therefore also referred to as an automobile air conditioner, the present invention can broadly relate to various air conditioners in automobiles, and is not limited to automobile air conditioners only.

[0033] refer to figure 1 , the air conditioner in the first embodiment of the present invention will be described below.

[0034] A hybrid compressor 4 is connected thereto as part of the refrigeration circuit 1 . The hybrid compressor 4 includes a first compression mechanism and a second compression mechanism. The first compression mechanism is driven solely by the prime mover of the vehicle; and the second compression mechanism is driven solely by the electric motor and integrated with the first compression mechanism. The prime mover of the automobile, that is, the driving force generated by the engine 2 is transmitted to the first compression mechanism of the hybrid compressor 4 thr...

Abstract

An air conditioner for a vehicle uses a hybrid compressor (4) including a first compression mechanism driven by a first drive source (2) and a second compression mechanism driven by a second drive source (5), and a single discharge port connected to the first and the second compression mechanisms. The operation of the hybrid compressor is controlled by a controller (15) in accordance with a control mode. The controller has a first operation mode in which the first compression mechanism alone is driven, a second operation mode in which the second compression mechanism alone is driven, a third operation mode in which the first and the second compression mechanisms are simultaneously driven, and a fourth operation mode in which the first and the second compression mechanisms are simultaneously stopped. Depending upon various conditions, the controller selects, as the control mode, one of the first, the second, the third, and the fourth operation modes.

Description

[0001] This application claims priority from earlier applications JP 2002-014032, JP 2002-015391 and JP 2002-015393, the disclosures of which are incorporated herein by reference. Technical field: [0002] The present invention relates to an air conditioner for a motor vehicle, and more particularly to an air conditioner including a hybrid compressor for obtaining driving force from a prime mover and an electric motor other than the prime mover. The prime mover is the engine installed on the motor vehicle. Background technique [0003] Air conditioners mounted on motor vehicles such as automobiles are known. Such a car air conditioner includes a refrigeration system or a refrigeration circuit. The refrigeration circuit includes a compressor as one of the connecting parts. The compressor can be driven by the car engine or by a dedicated electric motor installed in the car. [0004] Japanese Unexamined Utility Model No. H6-87678 (JP 6-87678 U) discloses an automobile air co...
