摘要： PROBLEM TO BE SOLVED: To improve fuel consumption of an engine, in regard to an air conditioner for a vehicle which is driven by the engine and controls the capacity of a compressor on the basis of a cooling load.
SOLUTION: When the cooling load is large (an after-evaporation temperature TE is higher than a target after-evaporation temperature TEO+β), the capacity of the compressor 4 is compulsorily made to be the maximum capacity (=100%) independently of the cooling load. Thereby, the after-evaporation temperature TE can be immediately made to be lower than TEO+β, so that drive time of the engine 1 can be shortened in comparison with conventional art. As a result, the fuel consumption of the engine 1 can be markedly improved in comparison with conventional art.

摘要： PROBLEM TO BE SOLVED: To reduce the working rate of an engine for a hybrid automobile or an automobile having an idling stopping function.
SOLUTION: Switching reference refrigerating capability which becomes a threshold value for switching an engine driven time and a motor driven time when a vehicle is stopped is changed for a defrosting operation time, and a time other than the defrosting operation time. That is, switching reference refrigerating capability A at the defrosting operation time is made large than switching reference refrigerating capability B at a time other than the defrosting operation time. Thus, the operation rate for an electrically operated motor 5 is made larger than the operation rate of the engine 1. Therefore, a frequency for driving a compressor 6 by the engine 1 can be reduced, and fuel consumption can be improved. At the same time, a starting frequency for the engine which is not expected by passengers can be reduced, and the deterioration of a riding feeling can be prevented.

摘要： PROBLEM TO BE SOLVED: To make the starting sound of a compressor by a motor hard to be heard by passengers in an air-conditioner for a vehicle being loaded on the vehicle which stops the engine when being temporarily stopped. SOLUTION: This air-conditioner for a vehicle is loaded on the vehicle which stops the engine when being temporarily stopped. The air-conditioner for the vehicle is equipped with the compressor which is driven by the engine and compresses a refrigerant, the motor which drives the compressor at least when the engine is stopped, an evaporator which is connected with the intake side of the compressor and cools air, an air blower which feeds air into the cabin through the evaporator, and a control device which controls the air blowing amount of the air blower. When the air blowing amount of the air blower right before the engine is stopped is less than an intermediate air volume which is increased by a specified air volume from the minimum air volume of the air blower right before the vehicle is temporarily stopped, or when the engine is stopped, the control device increases the air blowing amount of the air blower to the intermediate air volume.

摘要： PROBLEM TO BE SOLVED: To reduce the manufacturing cost of a scroll compressor while preventing the cracking and breakage of a joint portion (the root of a spiral wall) on the spiral center side and decreasing efficiency of the compressor. SOLUTION: The radius (r) of curvature of a joint portion 12a between a spiral wall 12 and a base 11 is made constant over the whole periphery in the spiral direction and an angular portion 12b of the spiral wall 12, corresponding to the, joint portion 12a, is formed in an approximately circular shape. Therefore, no recombination of an end mill is required over the whole periphery in the spiral direction and machining work is done by one end mill, resulting in a less number of manufacturing processes. As a rounded portion 12c is formed on the angular portion 12b, a gap δ formed between the angular portion 12b and the joint 12a can be smaller. The manufacturing cost can be reduced, accordingly, while preventing the cracking and breakage of the joint 12a on the spiral center side and the decreasing efficiency.

摘要： PROBLEM TO BE SOLVED: To prevent the breakage of spiral portions without marring the efficiency (capacity) of a scroll compressor. SOLUTION: Escape portions R are formed on a center side and on an outer periphery side and a middle portion is formed to ensure contact with both spiral portions 122, 132. At this time, a range on the center side is set at a winding angle Y or less determined by 32(X-1) and a range on the middle portion is set at 380 degrees, where X is winding numbers of spiral portions 122, 132. In this way, as excessive pressure rise in an operation chamber P on the center side is prevented, the breakage of both spiral portions 122, 132 are prevented while avoiding lower efficiency (capacity).

摘要： PROBLEM TO BE SOLVED: To stabilize an idling with reducing the manufacturing cost of a controller.
SOLUTION: A required torque to drive a compressor 2 with a controller 14 for air conditioning and an engine controller 19 respectively is calculated. This enables the reduction of the manufacturing cost of the controller 14 for air conditioning and the engine controller 19, because it is not necessary to install a communication means for transmitting and receiving the information about the drive torque between the controller 14 for air conditioning and the engine controller 19 for both the controllers. Then, an idling rotational speed of an engine 11 can be stably controlled independently of an air conditioning load without driving up the manufacturing cost of a vehicle.

摘要： PROBLEM TO BE SOLVED: To provide a hybrid compressor which can be rapidly reset in a capacity when started to be driven by an electric motor 6 and to provide its controller.
SOLUTION: When the compressor 4 is started to be driven by the electric motor 6, current of a capacity control valve 4a is first set to an initial control value SS for increasing a capacity larger than a control value S to a volume obtained from the state of a refrigerating cycle 5 to thereby make a chance of early inclining a swash plate 41, and is thereafter controlled to a control valve current S to a volume obtained from the state of the cycle 5. Thus, when the drive by the motor 6 is started, the capacity can be rapidly reset.
