Abstract: An air conditioning apparatus for a vehicle includes a front air-conditioning unit for adjusting a temperature of air blown toward a front seat side in a passenger compartment, and a rear air-conditioning unit for adjusting a temperature of air blown toward a rear seat side in the passenger compartment. In the front air-conditioning unit, a ratio between an amount of air passing through a front heater core and an amount of air bypassing the front heater core is adjusted by an air mixing door, and the temperature of air blown toward the front seat side in the passenger compartment is adjusted by the rotation of the air mixing door. 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: In a vehicle air-conditioning system, plural electrical members such as a blower controller, servomotors and a post-evaporator temperature sensor are collectively disposed on an electrical circuit board integrally formed with an evaporator case cover for closing a side surface of an evaporator case. Therefore, a wire structure of an electrical connection or a wire harness can be made simple. Further, because an elastically deformable sensor-pressing portion for pressing the post-evaporator sensor toward an evaporator side surface is integrally formed with the evaporator case cover integrated with the electrical circuit board, a contact pressure of a temperature sensitive portion of the post-evaporator sensor onto the evaporator side surface can be maintained.

Abstract: A vehicle air conditioner has a non-contact temperature sensor for detecting a surface temperature of a detection range of a passenger compartment. The detection range includes a first detection portion in which a surface temperature is changed to approximately correspond to an inside air temperature, a second detection portion in which a surface temperature is changed in accordance with an outside air temperature, and a third detection portion in which a surface temperature is changed in accordance with a sunlight amount entering the passenger compartment. In the vehicle air conditioner, a target temperature of air blown into the passenger compartment is calculated based on a set temperature and a surface temperature from the non-contact temperature sensor, while air-conditioning performance is improved.

Abstract: A vehicle air conditioner includes an air conditioning unit where temperature adjustments of both right and left-seat side air-conditioning zones are independently performed. In the vehicle air conditioner, a swing range of right-seat side center louvers provided in a right center face air outlet is restricted from a front right-seat direction to a rear left-seat direction, and a swing range of left-seat side center louvers provided in a left center face air outlet is restricted from a front left-seat direction to a rear right-seat direction. Thus, right-left independent temperature control can be accurately performed in the vehicle air conditioner.

Abstract: A heat exchanger a width dimension of which is much larger than a height dimension, in which an heat-exchanging medium flow resistance in a heat exchanging core portion is suppressed from increasing, and discharged air temperature is made uniform in the width direction of the heat-exchanging core portion. The heat-exchanging core portion is divided into a first core portion and a second core portion. The hot water in the first core portion and hot water in the second core portion flow in an opposite direction to each other. Thus, even when the heating heat exchanger, the width dimension of which is much larger than the height dimension, is used, the air temperature is prevented from varying in the width direction. Further, as the heat-exchanging medium flows in the first and second core portions in parallel, the heat-exchanging medium flow resistance is suppressed from increasing.

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 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: An engine cooling apparatus suitable for use in a vehicle shortens engine warm-up time without decreasing the heat-radiation capacity of a radiator. A shroud is disposed between a radiator and a water-cooled engine. A first air passage for blowing air toward the engine and its auxiliaries is formed in the upper side of the shroud, and a second air passage for discharging air having passed through the radiator to outside the engine compartment is formed in the lower side of the shroud. Accordingly, air is prevented from directly striking the engine and from passing around to the upstream side of the radiator through gaps between the walls of the engine compartment and the radiator. Thus the engine warm-up time is shortened without reducing the heat-radiation capacity of the radiator.

Abstract: A vehicle air-conditioning system for achieving a comfortable blowout state of conditioned air at all times both with respect to air-conditioning load factors which change frequently, like solar radiation strength, and with respect to air-conditioning load factors which change slowly, like passenger compartment temperature, by automatic control of grill louver swing control times corresponding to different air-conditioning loads. For example, when it can be estimated that solar radiation is incident on a driver side or passenger side front or rear seat occupant, oscillating driver side and passenger side center louvers are paused at a swing end of the occupant estimated to be exposed to solar radiation for a time that corresponds to the amount of cooling load. Therefore, it is possible to direct conditioned air at an occupant exposed to sun and thus improve the comfort of occupants upon whom sun is incident.

Abstract: According to the present invention, even when the two-layer mode in which the inside air is introduced into a first air passage and the outside air is introduced into a second air passage is set, it is further determined whether air mix doors are controlled at the maximum hot positions. When it has been determined that the air mix doors are controlled at the maximum hot positions, the inside/outside air introduction mode is still set to the two-layer mode, because the temperature difference due to the outside air temperature is small, however, otherwise, the inside/outside air introduction mode is not set to the two-layer mode but is set to a mode in which the outside air is introduced into the both air passages. In this way, it is possible to prevent the difference between the temperatures of the air blown out from a defroster opening portion and a foot opening portion from being increased due to the temperature of the outside air.
