Abstract: In a vehicle air conditioning system, a cold accumulator is disposed between a downstream air side of a cooling heat exchanger and an upstream air side of an air mixing door, to be cooled by cold air having passed through the cooling heat exchanger. Therefore, the cold accumulator can be readily cooled by the cold air from the cooling heat exchanger, while having a simple structure. Further, the cold accumulator is disposed at the upstream air side of the air mixing door, the cold accumulator can be effectively cooled without being affected by a rotation position of the air mixing door.

Abstract: In a vehicle air-conditioning system, an evaporator is disposed in an air-conditioning case to form a bypass passage through which air bypasses the evaporator, and an opening degree of the bypass passage is adjusted by a bypass door. When a vehicle engine operates, the system performs a cold-storing mode where cold quantity stored in condensed water on the evaporator is increased. On the other hand, when operation of the vehicle engine is stopped, the system performs a cold-releasing mode where air passing through the evaporator is cooled by cold released from frozen condensed water. During the cold-storing mode and the cold-releasing mode, temperature of air blown into a passenger compartment can be adjusted by adjusting the opening degree of the bypass passage. Thus, in the vehicle air-conditioning system, cold-storing quantity in the evaporator can be improved while power-saving effect of the vehicle engine is improved.

Abstract: An electric power unit is composed of a secondary battery, a cooling fan, a fan motor and a case for the secondary battery, the cooling fan and the fan motor.

Abstract: An electric element (Peltier element composite) is disposed in a boundary between an outside air introduction passage and an inside air introduction air passage (114). The Peltier element composite absorbs heat from the inside air in the inside air introduction passage to cool and dehumidify the inside air and radiates heat to outside air in the outside air introduction passage. The inside air and outside air are blown out from a defroster air outlet through a second air passage. In this way, it is possible to increase an amount of introduced inside air and to improve the heating performance while maintaining the defrosting performance.

Abstract: A motor vehicle dehumidifier, including a dehumidifying drying agent, that can provide a required dehumidifying capacity with a reduced overall quantity of drying agent compared to conventional drying agent-based dehumidifiers. In the present invention, a heat exchanger is disposed on an upstream side of a drying agent unit, and heat is exchanged in the heat exchanger between inside air to be dehumidified and low-temperature outside air used to cool the inside air. The air cooled by the heat exchanger flows into the drying agent unit and is dehumidified. Because the air has an increased relative humidity as a result of being cooled, the amount of water adsorbed from it per unit of drying agent is increased, as the water adsorption characteristic of the drying agent is greatly influenced by the relative humidity of the air passing over it, and is markedly improved by an increase in the relative humidity of that air.

On the other hand, in the rear air-conditioning unit, a flow control valve for controlling a flow rate of hot water flowing into a rear heater core is provided, and the temperature of air blown toward the rear seat side in the passenger compartment is adjusted by the flow control valve.

Abstract: When the engine is stopped while the engine is warmed up, the cooling water in the engine stays therein without flowing out of the engine, and the cooling water in the radiator or the bypass passage is used for heating source for the heating operation. In this way, it is possible to heat the passenger compartment continuously even after the engine is stopped and to suppress the temperature of the cooling water from lowering to reduce the emission at restarting of the engine.

Abstract: A main evaporator cools a driver's compartment of a vehicle while a cooling storage evaporator cools cooling storage packs that are used in cooling a sleeping compartment. Refrigerant is supplied to the main evaporator at the actuation of a first solenoid valve while refrigerant is supplied to the cooling storage evaporator at the actuation of a second solenoid valve. If a first switch is being actuated after the completion of the cooling storage operation of the cooling storage evaporator on the cooling storage packs and the temperature of the cooling storage packs is no more than a preset temperature, for example, -5.degree. C., FIR control is performed for alternately actuating the first solenoid valve and the second solenoid valve based on a predetermined time ratio (for example, 10 minutes 15 seconds).
