  • Patent number: 6360958
    Abstract: In an air conditioning apparatus for a vehicle, an amount of hot water flowing from an engine into a heater core is adjusted by a flow control valve so that temperature of air blown from the heater core is adjusted. A water pump driven by the engine is disposed in a water circuit so that hot water circulates between the engine and the heater core. The flow control valve includes a bypass passage through which hot water bypasses the heater core and a pressure response valve for adjusting an opening degree of the bypass passage. An opening degree of the flow control valve is controlled by a control unit so that the amount of hot water flowing into the heater core is adjusted. In the air conditioning apparatus, the opening degree of the flow control valve is corrected by the control unit to reduce variation in the amount of hot water flowing into the heater core due to variation in a rotation speed of the engine.

  • Patent number: 6308770
    Abstract: According to the present invention, an air conditioning apparatus include a case partitioned into a first air passage and a second air passage by partition plates (16-19), a heat exchanger such as a heater core. The heater exchanger is sandwiched between the partition plates. Further, the heat exchanger is formed by laminating tubes and a fin while the fin is disposed in each main air passage formed between tube walls of the tubes. Each end of the partition plates is opposite to each end of the tubes so that the partition plates are parallel to the tubes. In this way, airflows which respectively have passed from the air first and second passages pass through the heat exchanger without being mixed with each other therein. As a result, the separation characteristics of airflows can be improved.

  • Patent number: 6213198
    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.

  • Patent number: 6145754
    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.

  • Patent number: 6070425
    Abstract: In an air conditioning apparatus, an evaporator is disposed in an air-conditioning case to be inclined relative to a horizontal direction and to form a lower space below the evaporator. Air flows through the evaporator from a lower side toward an upper side thereof in the air-conditioning case. The lower space is partitioned by a partition member into an air-blown space and a drain space, and a drain guide member is disposed in the drain space to approximately contact a lower end portion of the inclined evaporator, where condensed water is gathered. Therefore, it can prevent air from hitting from below against the lower end portion of the evaporator. Consequently, the condensed water that has been gathered at the lower end portion of the inclined evaporator can be discharged rapidly along the drain guide member without being affected by the flow of air, and drips to a bottom surface of the air-conditioning case.

  • Patent number: 5857905
    Abstract: An air conditioning apparatus includes an air conditioning case having therein first and second air passages partitioned from each other. First and second fans are respectively disposed in the first and second air passages, and an outer diameter of the first fan is smaller than that of the second fan. Therefore, an air volume relative to a total pressure in the first fan is greatly changed as compared with the second fan. Thus, when an operation mode is switched from a foot air mode to a foot/defroster air mode or from the foot/defroster air mode to the foot air mode, an opening degree of a defroster door is changed slightly.
