摘要:
Components for HVAC systems used in hybrid and fuel cell vehicles are mounted in modular configuration on a frame with air conditioning components connected to one another by metal pipes welded to the components. An alternating current motor, integral with a compressor, is driven by 310 volt alternating current from an inverter, which inverter converts 310 volt direct current that is used to power the vehicle. PTC heaters in fluid communication with an evaporator employed by the air condition system are directly energized by the 310 volt direct current. The modular system is mounted directly on the chassis of the vehicle, facilitative assembly of the vehicle, and is readily removable as a unit from the chassis for repair or replacement.

An air conditioning module is constructed to include all the necessary components for an air conditioning system within a single housing, with the housing having a supply air opening and a return air opening. The various components within the housing are so situated that the return air opening is relatively large in its lateral extension across the roof of a bus such that a single module can accommodate various configurations and locations of the supply air and return air openings in the roof of a bus.

A module for a bus rooftop air conditioner is self contained in that it has all the necessary components including a compressor, if desired, which when supplied with electrical power, can provide conditioned air to the passenger compartment of a bus. In addition, an electrically powered heater is provided in the air flowstream such that heated air can also be supplied to the passenger compartment when desired. Multiple units provide for incremental capacity requirements to be met as well as limp home capabilities.

A seat air conditioner for a vehicle seat includes a seat air passage that is provided in at least one of a seat back and a seat cushion having a seat surface and a pad covered by the seat surface. The seat air conditioner further includes a blower unit disposed at a back side of the pad. The seat air passage has an air distribution passage embedded within the pad and a connection hole passage extending from a predetermined portion in the air distribution passage to the blower unit. The air distribution passage extends in a surface direction in a pipe shape to have a predetermined pattern. Since the air distribution passage is provided inside the pad, seat surfaces of the seat cushion and the seat back can be made smooth, and comfortable seating feeling can be given to a user.

In a vehicle air conditioner, a compressor is driven by a vehicle engine when an actual temperature of an evaporator is higher than a basis temperature that is higher than a target temperature by a predetermined temperature, and is driven by an electrical motor when the actual temperature of the evaporator is lower than the basis temperature. The predetermined temperature is set to be higher as the target temperature of the evaporator decreases such that the basis temperature is not higher than a comfortable limit temperature. Accordingly, the compressor can be driven by the electrical motor in a range where the actual temperature can be controlled to be not higher than the comfortable limit temperature. Therefore, fuel consumption efficiency of the engine can be improved, while a minimum of cooling capacity can be ensured.

A vehicle air conditioning apparatus for a vehicle comprises an air conditioning unit for conditioning air in a passenger compartment of a vehicle. The air conditioning unit has an air conditioning case forming an air passage with at least one sidewall. The sidewall of the air conditioning case is divided into a plurality of partial sidewalls, the thicknesses of which are different, so as to restrain vibration of the air conditioning case. The air conditioning apparatus further characterized in that the air conditioning case is installed at one of a front part and a rear part of the passenger compartment of the vehicle. The thicknesses of adjoining two of the partial sidewalls are different correspondingly to vibration restriction performance of the sidewall of the air conditioning case.
摘要:
An air conditioning apparatus preferentially ventilates a space close to a seat and/or a steering wheel on which a passenger directly makes a contact in a passenger compartment while a vehicle is parked. The uncomfortable feeling of a passenger that might occur when he/she is getting into the parked vehicle can be reduced using a small capacity in the air conditioning as compared to the air conditioning apparatus ventilating the whole space in the vehicle.

A heating, venting, and air conditioning system utilizes a reformer to provide supplemental heat to a passenger compartment and to improve start-up emissions of an engine of a vehicle or power system. A pump circulates a fluid through the engine and throughout the system. A radiator and heater core transfer heat from the fluid. A first circuit cools the fluid upon circulation through the radiator after circulation through the engine to cool the engine, and a second circuit heats the passenger compartment and cools the fluid upon circulation through the heater core after circulation through the engine to cool the engine. The reformer, which converts a hydrocarbon or alcohol fuel into a reformate, generates heat. A third circuit, defined between the reformer and the pump and interconnected with the heater core, provides the supplemental heat from the reformer to the passenger compartment through the heater core and also to the engine.

This temperature regulation apparatus comprises a heat pump (12) comprising a main compression circuit (14) for a refrigerant fluid taking heat from a cold source (16) and transferring it to a hot source (18). The cold source (16) comprises a first heat exchanger (24) for exchanging heat between the refrigerant fluid and a liquid coolant thermally coupling the main refrigerant circuit (14) to a first secondary coolant circuit (26). The first secondary circuit (26) has selective connection means (40, 52, 54) for selectively connecting it to the upstream and downstream ends (48A, 48B) of a nullheaternull branch (48) of a cooling liquid circuit (46) of an exothermal part of the vehicle. The exothermal part is preferably a heat engine of the vehicle. The invention is applicable to air conditioning a motor vehicle cabin.
摘要:
In a vehicle air conditioner, air having passed through a heat exchanger of an air conditioner unit is introduced to a plurality of wall outlet portions formed on walls of a compartment and blown off into the compartment. The air conditioner unit includes a plurality of temperature control means for independently controlling at least one of volume and temperature of the air flowing into the compartment through the respective wall outlet portions.
