摘要： To control fluctuation of blown air temperature of a heat exchanger to a small value without adding a movable mechanism such as a variable restricting valve, a heat exchanger for heating air by exchanging heat between hot water supplied from a water-cooling type engine and air, a flow control valve for controlling a hot water flow amount to the heat exchanger and a bypass circuit for allowing hot water to flow while bypassing the heat exchanger are provided. A pressure-responsive valve is provided on the bypass circuit and an opening degree of the bypass circuit corresponding to a pressure rise of the hot water is increased. The flow of returning hot water from the heat exchanger is blocked by the flow of the bypass side hot water at a merging portion where the bypass side hot water discharged from the pressure-responsive valve merges with the returning hot water discharged from the heat exchanger.

摘要： A flow-quantity control valve controlling hot-water flow to a heat exchanger and a bypass circuit allowing hot water to bypass the heat exchanger are provided along with a pressure-actuated valve in the bypass circuit which is responsive to a pressure increase of hot water from an engine. Inlet-side opening portions, outlet-side opening portions, and a bypass-side opening portion are provided in a control passage of a valve body of the flow-quantity control valve. Main flow of dynamic pressure of hot water sprayed from portions on a small opening-degree side act upon a valve body side of the pressure-actuated valve. Due to this, dynamic pressure of the hot water in a small opening-degree region of the flow-quantity control valve can be effectively used to increase a valve-lift quantity of the pressure-actuated valve, thereby reducing a fluctuation range of blown-air temperature of the heat exchanger. Also, the flow may be bent so that hot-water flow having a high dynamic-pressure component from the hot-water inlet pipe is not applied directly to the valve body of the differential-pressure valve; thus, lift of the differential-pressure valve can be prevented from becoming excessive, and a drop in heat-exchanger blown-air temperature at a predetermined opening-degree position of a flow-quantity control valve can effectively be suppressed.

摘要： The air-conditioning unit includes an air-conditioning case, a heater, a bypass path bypassing the heater, an air-mixing chamber, an air-mixing door, and an air opening. The air-conditioning unit also includes an auxiliary door arranged in series with the air-mixing door in the bypass path. The auxiliary door is operated between at a first position and at a second position. The auxiliary door in the first position closes the bypass path more than in the second position. The auxiliary door is operated at the first position at least when the air-mixing door opens the bypass path slightly.

摘要： In an air conditioner for a vehicle, a blower of a blower unit includes a double-axial motor having a rotation axis positioned approximately in a vehicle top-bottom direction, a pair of centrifugal fans located at two sides of the double-axial motor in an axial direction, and a pair of scroll casings in which the centrifugal fans are accommodated, respectively. The two air outlet portions are arranged in the vehicle top-bottom direction, and are adjacent to be joined to an air inlet portion of the air conditioning unit, substantially as a single air outlet. Furthermore, the two air outlet portions are located approximately at the same height position as that of the air passing portion of the cooling heat exchanger, and have a height dimension (H2) at its downstream end side that is approximately equal to a height dimension (H1) of the air passing portion of the cooling heat exchanger.

摘要： An air passage flow control device according to the invention includes a plate member having at least one aperture through which air may pass, the degree to which the aperture is exposed being controlled by the positioning of a film member across at least a portion of the aperture. The positioning of the film member relative to the aperture is controlled by rolling and unrolling a portion of the film member on a rotating member that may be selectively moved back and forth across the aperture. By rolling and unrolling the film member to control the opening of the aperture, the present invention avoids relative lateral movement of those portions of the film member that are in contact with the plate member, thereby reducing the frictional forces. Further, the rotating member is configured to reduce the collection of particulate matter on the rotating member and the film member.

摘要： A heater for an air conditioner includes plural water tubes and plural refrigerant tubes which are arranged in parallel in an air flow direction. Therefore, the heater can heat air by using at least one of the heating sources while a pressure loss in the heater can be effectively reduced. For example, in a quick-heating mode, high-temperature refrigerant from a refrigerant cycle flows into the heater to heat the blown air, and low-temperature engine-cooling water from an engine bypasses the heater. In this case, thermal leakage from the refrigerant to the engine-cooling water is avoided.

摘要： An air-conditioning case of an air-conditioning unit forms air passages therein. A film member is reciprocably supported in the case and has free ends. Reinforcing members are secured to the lower end of the film member. A drive force for reciprocating the film member is applied to the film member from a motor through a drive shaft and drive gears, which are attached to the drive shaft, to open and close the air passages with the film member. When the film member is moved upwardly, the reinforcing members abut against positioning portions of the case to position the film member at a predetermined position.
