20110114739 | Vehicular air conditioner - When there is no occupant in seats other than a driver seat during a foot mode, an air-conditioning controller executes a single seat concentration mode to prevent blowing of warm air to a passenger seat and a backseat by closing foot outlets on a passenger seat side and a backseat side. In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature. Thus, an electric power consumed by an electric motor of a blower can be reduced, thereby realizing energy saving. | 05-19-2011 |
20110120146 | Air Conditioner for vehicle - An air conditioner for a vehicle includes first and second heating heat exchangers disposed to heat air by using a cooling fluid for cooling an engine as a heat source, a heater disposed to heat the cooling fluid flowing to the second heating heat exchanger, and a controller that outputs an operation request signal to the engine when a temperature of the cooling fluid is lower than a predetermined temperature. The first and second heating heat exchangers are arranged in parallel with respect to a flow direction of the cooling fluid. In the air conditioner, the controller controls a flow amount of the cooling fluid flowing into the second heating heat exchanger to be, smaller than a flow amount of the cooling fluid flowing into the first heating heat exchanger when the heater heats the cooling fluid flowing to the second heating heat exchanger. | 05-26-2011 |
20120061365 | Radiation heating system for vehicle - A radiation heating system for a vehicle includes a heating device and an exterior member. The heating device serves as a heat source and is for generating radiation heat to warm up an interior of the vehicle. The exterior member is disposed on a vehicle interior-side of the heating device. Given that: thermal transmittance of the exterior member is K′ [W/(m | 03-15-2012 |
20120102974 | Air conditioner for vehicle - In a vehicle air conditioner, a heating heat exchanger is disposed in an air passage of a casing to heat air to be blown toward a vehicle compartment by performing heat exchange between air and a heating fluid, a heat radiation portion is disposed to radiate heat to the heating fluid before being heat-exchanged in the heating heat exchanger, a heat absorption portion is disposed to absorb heat from the heating fluid after being heat-exchanged in the heating heat exchanger, and a Peltier element is disposed between the heat radiation portion and the heat absorption portion to pump heat from the heat absorption portion to the heat radiation portion. Furthermore, the heat radiation portion is disposed in the air passage of the casing, in which the heating heat exchanger is disposed. Thus, heat discharged from the Peltier element can be effectively used. | 05-03-2012 |
20120129439 | AIR CONDITIONING SYSTEM FOR VEHICLE - An air conditioning system for a vehicle includes a seat part having a seating surface and an air flow passage, an air conditioning unit, and a blower. The passage includes a suction port on the seating surface and an air outlet at a region of the seat part other than the seating surface. The unit includes a face air outlet and a lower air outlet through which conditioned air from the unit is blown out toward the seating surface. The blower forms a flow of air in the passage from the suction port toward the air outlet. At time of cooling vehicle interior by the unit, the conditioned air blown out of the lower outlet is suctioned from the seating surface, and air that has passed through the passage is blown out of the region of the seat part other than the seating surface. | 05-24-2012 |
20120142264 | AIR CONDITIONER FOR VEHICLE - A vehicle air conditioner includes a blower for blowing air into a space of a vehicle compartment, and an air-conditioning mode switching portion for switching between air conditioning modes. The air conditioning modes include a normal air conditioning mode in which air conditioning of a specific region including a driver seat and air conditioning of a non-specific region not including the specific region in the space of the vehicle compartment are performed, and a specific-region prioritizing air conditioning mode in which an air conditioning capability for the non-specific region is decreased as compared to the normal air conditioning mode. The air-conditioning mode switching portion adjusts the air conditioning capability for the non-specific region based on a pressure of air drawn into the blower, in the specific-region prioritizing air conditioning mode. | 06-07-2012 |
20120180989 | VEHICULAR AIR-CONDITIONING SYSTEM - A heating-use heat exchanger which includes a first heater core which exchanges heat between a first liquid and air blown into a passenger compartment and a second heater core which exchanges heat between a second liquid which is higher in temperature and smaller in flow rate than the first liquid and blown air which is heated by the first heater core is held in an air-conditioning case so that an inlet side tank part is at the bottom and an exit side tank part is at the top and the tube longitudinal direction is slanted. Due to this, the high temperature second liquid flowing into the second heater core is stored inside of the inlet side tank part in a region above the tube inlet side ends over the entire stacking direction of the plurality of tubes, then flows into the plurality of tubes. | 07-19-2012 |
20120234932 | VEHICULAR HEATING SYSTEM - A vehicular heating system comprising a passenger compartment air-conditioner and a radiative heater which heats a foot area of a passenger, said vehicular heating system detecting foot vent heat which said foot vent air flow has and controlling said passenger compartment air-conditioner and said radiative heater in accordance with that heat. | 09-20-2012 |
20120267354 | RADIANT HEATING SYSTEM FOR VEHICULAR USE - A radiant heating system for vehicular use which is attached to an interior member of a passenger compartment, has a heating means for generating radiant heat, a protective member which is arranged at a passenger compartment side from the heating means and which prevents a driver from contacting the heating means, and supporting members which support the protective member, wherein the front surface of the protective member is provided with a plurality of projecting members, the supporting members are provided so as to form an air space at an opposite side of the protective member from the compartment side, the protective member flexes when the driver pushes against one of the projecting members, projecting members which adjoin the pushed member tilt to the pushed member side, and the distances between the front ends of the pushed projecting member and the adjoining projecting members become smaller. | 10-25-2012 |
20130059522 | AIR CONDITIONER FOR VEHICLE - An air conditioner for a vehicle includes an electric heater arranged downstream of a heat exchanger in an air flow direction, a defroster air outlet, a driver-foot air outlet through which air is blown toward a foot area of a driver, a knee air outlet through which air is blown toward a knee area of the driver, a door device which controls an air amount blown into a vehicle compartment by opening or closing the air outlets. When an immediate heating operation is performed by an operation of an immediate heating switch, the door device opens the defroster air outlet and at least one of the driver-foot air outlet and the knee air outlet, and the electric heater heats a total amount of air that is to be blown through the at least one of the driver-foot air outlet and the knee air outlet. | 03-07-2013 |
20130298851 | CONTROLLER FOR ENGINE COOLING SYSTEM - An internal combustion engine has a cylinder-head-passage through which an engine coolant flows toward a water jacket when a water pump is operated. The water pump is an electric water pump utilizing the electric power charged in the battery. A radiator is provided in the cylinder-head-passage.
