摘要:
A detector detects a remaining power of a battery. A calculator calculates a demand load of air-conditioning based on at least one of a preset temperature set for air in a passenger compartment of an electric vehicle and an outside temperature of air outside of the electric vehicle. A switching portion switches a mode of air-conditioning between a battery mode and an engine mode based on the calculated demand load and the detected remaining power of the battery. The battery mode causes the battery to supply electric power for air-conditioning, and the engine mode causes an engine of the electric vehicle to supply combustion energy for air-conditioning.

A vehicle is provided with an air conditioning device that heats a passenger compartment, using cooling water passing through an internal combustion engine as a heat source, and a seat heater, which heats a seat in the passenger compartment by using an electric power from a battery as a heat source. An electronic control device performs EV travel of the vehicle by driving a motor generator while setting the internal combustion engine to a stop state and restarts the internal combustion engine when a cooling water temperature becomes equal to or less than a predetermined temperature during the EV travel. When a heating request is output to make the air conditioning device heat the passenger compartment during vehicle travel, the electronic control device reduces the heating degree of the air conditioning device and increases the heating degree by the seat heater during EV travel in comparison with non-EV travel.

When there is an extremely low ambient temperature, an electronic control unit controls operation of a circulation path for coolant water in such a manner that, after starting of an engine, the coolant water is supplied from the engine first to a throttle valve and an EGR valve and then to an oil warmer for a transmission. This solves a failure problem in the throttle valve and the EGR valve caused by frost formation at an early stage. As a result, desired operating performance of the vehicle is quickly ensured and heat management in the vehicle is carried out in a desired manner when there is an extremely low ambient temperature.

A fluid machine includes a fluidization portion for compressing or expanding a working fluid which is heated to be brought into a vapor phase state after circulating in a cycle, an oil storage portion for storing therein lubricant oil for lubricating a sliding surface of the fluidization portion, a lubricant oil feed passage for guiding the lubricant oil stored in the oil storage portion to a sliding portion of the fluidization portion by a flow of the working fluid, and a sliding surface pressure adjustment portion that is controlled to adjust a sliding surface pressure of the sliding portion. The working fluid flows inside the machine with the sliding surface pressure of the sliding portion decreased as compared with that in a normal operation of the fluidization portion by the sliding surface pressure adjustment portion, and thereafter the decreasing of the sliding surface pressure by the sliding surface pressure adjustment portion is released.

A fluid machine includes a stationary scroll member and a movable scroll member. A second tooth portion of the movable scroll member is arranged to be revolved with respect to a first tooth portion of the stationary scroll member and to form an operating chamber between the movable scroll member and the stationary scroll member. The operating chamber is changeable in accordance with a revolution of the movable scroll member to be defined between two sliding contact portions, and is dividable into first and second operating chambers. The second tooth portion is provided with a passage portion through which an introducing port for introducing a fluid to the operating chamber communicates with the second operating chamber when the introducing port communicates with the first operating chamber. The passage portion disconnects the introducing port from the second operating chamber when the introducing port is disconnected from the first operating chamber.

A complex fluid machine has an expansion-compressor device, a pump, and a motor generator. The expansion-compressor device, the pump, and the motor generator are operatively connected and arranged in series. A portion of an outlet side passage formed in the fluid machine, through which the working fluid flows from the expansion device, is arranged adjacent to a portion of a pump outlet-side passage formed in the fluid machine, through which the working fluid flows from the pump, so that heat of the working fluid in the outlet side passage is transferred to the working fluid in the pump outlet-side passage.
