Automotive air conditioning system
An air conditioning system for use in a motor vehicle powered by an internal combustion engine is described. The system comprises an electric motor powered by a battery; a compressor arranged to be powered by at least one of the internal combustion engine and the electric motor; and a control unit that controls the driving of the compressor. The control unit is configured to execute driving the compressor by only the electric motor when the combustion engine is under an idling stop; restarting the combustion engine upon expiration of a first given time from the time when the idling stop has occurred, so that thereafter the compressor is driven by both the combustion engine and the electric motor; and stopping the driving of the compressor by the electric motor upon expiration of a second given time from the restarting of the combustion engine, so that thereafter the compressor is driven by only the combustion engine.

To keep a temperature of an interior of an automotive vehicle at least at a level of an external atmospheric temperature even if the vehicle is parked with an engine being stopped for a long time, an automotive air-conditioning apparatus is composed of a cooling device 12 to be controlled by a controller 13, a pre-cooling device 20 for pre-cooling the interior of the vehicle, and a sub-controller 18 for controlling the pre-cooling device. The pre-cooling device is composed of a cooling thermoelectric element module 22, a ventilation fan 23, a solar battery 21 and a pre-cooling storage battery 24 charged by the solar battery. The sub-controller always operates the pre-cooling device 20 while the vehicle is stopped with the engine being stopped and starts the pre-cooling device 20, for example, one hour prior to a time when the vehicle starts to movement during parking for a long time in an interior parking lot or the like with the engine being stopped so that the temperature of the interior of the vehicle is kept at a temperature that does not so much exceed a set temperature, i.e., at least at the level of the external atmospheric temperature, until the engine is started.

Accumulator with pickup tube
A suction accumulator for refrigeration or air-conditioning system use, especially for automotive air conditioning system use, which comprises a “pickup tube” to withdraw liquid from a reservoir of the accumulator to return oil to the compressor. The accumulator has a deflector with an outlet tube, to help ensure that fluid does not flow directly from the inlet opening to the outlet opening of the accumulator. The relatively narrow second portion of the outlet tube is closer to the outlet opening than the first portion. The pickup tube is secured in communication with the relatively narrow second portion and optimises the oil return function, minimises restriction to refrigerant flow, maximises effective and actual reservoir volume, and minimises the amount of liquid delivered to the compressor at switch-off. Incorporating an electric heating element or a heat exchanger for engine coolant or exhaust allows the accumulator of the present invention to function as the evaporator when the refrigeration system is used in heat pump mode for heating applications.
