摘要： PROBLEM TO BE SOLVED: To improve ignitability of a combustion type heater. SOLUTION: A fuel heater 216 is situated between a fuel pump 22 and a glow plug 219. This constitution, since vaporized fuel is supplied to the glow plug 219, prevents the generation of a layer of vaporized fuel around the glow plug 219 even when the heat generation temperature of the glow plug 219 is maintained at a value higher than an ignition temperature of fuel. Thus, since fresh liquid fuel and oxygen (air) are smoothly supplied to the periphery of the glow plug 219, ignitability of fuel is improved.

摘要： PROBLEM TO BE SOLVED: To provide heat exchanger layout pursuing space efficiency and to reduce frosting on a case of an air-conditioning unit. SOLUTION: An evaporator 21 is disposed almost horizontally in a case so as to form a space on the lower side of the evaporator 21. The case below the lower side surface of the evaporator 21 is provided with a condensed water drain pipe 21c for draining condensed water produced at the evaporator 21. When the condensed water flows down and drains from the condensed water drain pipe 21c, the falling condensed water is heated by high temperature blast air before cooling, so that the outer surface temperature of the case is not lowered much. Frosting on the case is therefore reduced considerably or eliminated, so that an insulator (heat insulating material) to be mounted inside the case can be disused to further reduce cost.

摘要： PROBLEM TO BE SOLVED: To change the timing of switching of an operating condition of a swing louver either from excessive cooling control to semi-excessive cooling control or from the semi-excessive cooling control to stationary cooling control in such a manner that the change matches further with the feeling of air conditioning of an occupant. SOLUTION: The operating condition of a swing louver can be switched from excessive cooling control, in which either the direction of the air blown out of respective face blowout ports 21, 22, 31, 32 for air conditioning is directed to an occupant or the blowing state of the air conditioning air is concentrated upon the occupant in order to create an occupant-concentrated mode, to stationary cooling control, in which the quantity of the air conditioning air blowing toward the occupant is less than that in the case of the excessive cooling control. At this time, the higher the temperature of a car room, which is detected by a car-room-temperature sensor 91, is, the higher the prescribed value of the car-room temperature, at which the operating condition of the swing louver is switched, becomes. Thus, the local cooling, in which the occupant is exposed to air conditioning air for a long time, is restricted, thereby preventing the lowering of the feeling of being air conditioned of the occupant.

摘要： PROBLEM TO BE SOLVED: To set desired blowoff temperature distribution by a reheat type unidirectional heater core by regulating the temperature of hot water fed to a heating heat exchanger, to the mixing ratio of high temperature hot water from a hot water source and low temperature hot water after passing through the heating heat exchanger, and setting the quantity of hot water. SOLUTION: In the case of any mode other than a face mode, the lower target blowoff temperature is compared with the detection value of a second blowoff temperature sensor 29 to control the valve opening of a control valve 7. The temperature of air-conditioning air blasted into a foot air passage 20 is controlled, that is, the mixing ratio of high temperature hot water from an engine 2 and low temperature hot water after passing through a heater core 17 is regulated according to the valve opening of the contorl valve 7, and high temperature hot water to the heater core 17 is automatically regulated. The upper target blowoff temperature is then compared with the detection value of a first blowoff temperature sensor 28, and the hot water quantity supplied to the heater core 17 is controlled by the rotating speed of a motor- driven pump 11 to control the temperature of air-conditioning air to a face air passage 19. Desired blowoff temperature distribution can therefore be regulated and set.

摘要： PROBLEM TO BE SOLVED: To provide a seat air-conditioning device for a vehicle to switch cold air and room temperature air or hot air and room temperature air from each other and feed the air to a seat through simple structure. SOLUTION: A seat air-conditioning device 1 for a vehicle comprises a seat blast unit 3 arranged at the lower part of a front seat 2; and a blast duct 4 to feed conditioned air from an air-conditioning unit to the seat blast unit 3. The air-conditioning unit comprises a case 7 at the internal part of which a cold air passage 5 and a hot air passage 6 are formed; and a switch door 8 to switch the cold air passage 5 and the hot air passage 6 from each other in the case 7. The switch door 8 is driven to the hot air side when a room temperature is lowered from cool down and stabilized and cuts off the cold air passage 5. This constitution sucks indoor air through the foot air outlet 9 of an air-conditioning unit to the hot air passage 6, and causes a flow of indoor air through a blast duct 4 for the seat and feeds the indoor air to the seat 2 through the seat blast unit 3 and blows off the air from a seat surface.

摘要： PROBLEM TO BE SOLVED: To increase a heating capacity at the rise of the heating operation of an overall air conditioner unit by suppressing the extra heat loss of the air heated by an evaporator used as a hot gas heater. SOLUTION: In an air conditioner unit 1 in which an evaporator 8 is arranged in an air conditioner duct 2 and a hot water heater 3 is arranged on the air downstream side of the evaporator, when a cooling water temperature (TW) detected by a cooling water temperature sensor 38 is as low as below a specified level, an A/M door 5 is set at a MAX.COOL position to prevent the air heated by the evaporator 8 from being cooled by a low temperature cooling water flowing into a hot water heater 3. By this, a heating capacity at the rise of heating operation is increased. When the cooling water temperature(TW) is as high as over a specified level, the A/M door 5 is set at a MAX.HOT position to further heat the air heated by the evaporator 8 by the hot air heater 3. By this, the heating capacity is increased.
