摘要:
An air conditioner for automotive vehicles is disclosed. The flow rates of air supplied to an evaporator (4) and a heater (5) are adjusted by rotationally displacing a scroll casing (2b) and thus changing an air flow from a blower (2) to a predetermined direction. The air-mix door can thus be eliminated to allow a smaller size of an air-conditioner casing (3) (air-conditioning unit (1)). Also, the ratio between cool air flow rate and hot air flow rate is adjusted by rotationally displacing the scroll casing (2b) with a spur gear (2c) and, therefore, the size and the production cost of the air conditioner can be reduced as compared with a conventional system in which an air-mix door is swung by a link mechanism.

摘要:
A system with an internal combustion engine which has a heat transfer circuit, a fuel cell and a climate control unit which is accommodated in the heat transfer circuit of the internal combustion engine. The system has a heat transfer arrangement for transferring the exhaust heat of the fuel cell to the heat transfer circuit and a bypass for bridging a segment of the heat transfer circuit which runs through the internal combustion engine so that, in the bypassed operating state, an isolated circuit is formed. In stationary operation, this enables an optimized operating mode since the internal combustion engine is no longer heated and the exhaust heat of the fuel cell is fully available for heating purposes. The climate control unit can have a fuel cell and an arrangement for transferring the heat produced by the fuel cell to the vehicle interior has a fan unit by which an air flow can be produced for cooling the fuel cell and a heating unit which is powered by the fuel cell and by which the air flow for heating the vehicle interior can be additionally heated. For cooling or heating the interior of a motor vehicle, the system can have a cooling circuit with a compressor, a condenser, an expansion element, and a first evaporator and an APU or a fuel cell to electrically power the compressor, and a second cooling circuit a second evaporator, the second cooling circuit being connected to the first cooling circuit.

摘要:
In a left and right temperature independent control-type air conditioning unit for a vehicle, a case is constructed of a first case and a second case. An air passage in the case is divided into a first air passage through which air flows toward a right region of a compartment and a second air passage through which air flows toward a left region of the compartment by a partition wall. The first and second cases are connected by engaging a first case end surfaces with a second case end surface. Pin contact portions are formed on the first and second cases adjacent to the case end surface. The pin contact portions are disposed to oppose each other between the first case and the second case. The partition wall is fixed by interposing its periphery between the pin contact portions of the first and the second cases.

An evaporator unit for use in the air conditioning system of a mass transit vehicle that includes a housing mounted inside the air conditioned section of the vehicle having a return air inlet connected to a supply air outlet by a flow passage. The evaporator coil of the air conditioner is mounted in the flow passage to cool the air moving through the passage. A heater coil is mounted behind the evaporator coil to selectively heat the air moving through the passage. A dehumidifying coil is mounted in front of the evaporator coil that utilizes ambient air to dehumidify the indoor air when the ambient air temperature is at a temperature below that at which the air conditioner cannot reliably operate.

An vehicle air-conditioning system (1) according to the present invention has an evaporator (4) for receiving an air being discharged into a casing (2) of the system by a blower and changing it to a cold air flow, the cold air flow being allowed to flow rearward, and a heater (6) located downstream of the evaporator (4) for selectively receiving at least a portion of the cold air flow and heating it to a warm air flow. The air conditioning system (1) also has partition means (8) disposed downstream of the heater (6) for directing the warm air flow upwardly in such a manner as to permit mixing of the warm air flow through the heater (6) and the remaining cold air flow bypassing the heater (6) thereabove, the partition means (8) including a top end portion (10), and guide means (11) for downwardly directing the cold air, the warm air or the mixture of cold and warm airs which has flowed beyond the top end portion (11) of said partition means (8) for blowing-out. The top end portion (10) of said partition means (8) defines a surface (30) of a streamlined or curved configuration along which said cold air, the warm air or the mixture of cold and warm airs can flow.
