20110067422 | Air-conditioning device for vehicle - An air-conditioning device for a vehicle includes a blower and an estimating portion. The blower is disposed in an air-conditioning case, and performs a dry control for a heat exchanger arranged in a passenger compartment of the vehicle by sending air. The blower uses one of power supplied from an external power source, power supplied from the battery having residual quantity equal to or larger than a predetermined quantity, or power supplied from an in-vehicle solar cell, while the vehicle is parked. The estimating portion estimates an approximate elimination of odor generated from the heat exchanger by starting the sending of air, and stops the blower based on the estimation. | 03-24-2011 |
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 |
20120227428 | AIR-CONDITIONER FOR VEHICLE - An air-conditioner includes a heat pump cycle having an outdoor heat exchanger; a frost state calculator that calculates a degree of frost formed in the outdoor heat exchanger; an output portion that outputs an information of the frost; and a controller that instructs a defrosting operation for melting the frost by controlling the heat pump cycle. The controller controls the output portion to output the degree of frost when the defrosting operation is not performed, and controls the output portion to output a defrosting information representing that the defrosting operation is being performed when the defrosting operation is performed. | 09-13-2012 |
20130055746 | AIR CONDITIONER FOR VEHICLE - An air conditioner for a vehicle includes a cycle switching device. The cycle switching device switches a refrigerant cycle between a heating circuit, in which refrigerant flows through a heating heat exchanger, and a cooling circuit, in which refrigerant flows through a cooling heat exchanger. The air conditioner further includes an air conditioning controller, which controls the cycle switching device and includes a defroster control portion. The defroster control portion increases a temperature of air blown into the vehicle compartment through a defroster air outlet by a predetermined degree while keeping the refrigerant cycle at a state of the heating circuit for a predetermined time, when a defrosting operation is commanded to be performed during the heating circuit. | 03-07-2013 |
20130168458 | VEHICLE AIR CONDITIONER - An air conditioner is applied to a vehicle having a first operation mode in which an internal combustion engine-side driving force is more than a motor-side driving force, and a second operation mode in which the motor-side driving force is more than the internal combustion engine-side driving force, as an operation mode for the vehicle. The air conditioner includes a heater for heating air using a coolant of an internal combustion engine as a heat source, and a request signal output portion for outputting a request signal for increasing the number of revolutions of the internal combustion engine to a driving force controller during a heating operation of the vehicle interior. The request signal output portion outputs as the request signal, a signal that makes the number of revolutions increased in the second operation mode higher than that increased in the first operation mode. | 07-04-2013 |
20130206382 | AIR-CONDITIONER FOR VEHICLE - An air-conditioner conducts an air-conditioning for a passenger compartment of a vehicle, and has an eco-mode to save energy. The air-conditioner includes a seat temperature control system and a controller. The seat temperature control system is configured to operate to heat or cool a seat in the passenger compartment. The controller automatically activates the seat temperature control system when the eco-mode is set. | 08-15-2013 |
20130213631 | AIR CONDITIONER FOR VEHICLE - An air conditioner for a vehicle equipped with a battery includes an air conditioning unit, and a control unit. The air conditioning unit performs air-conditioning of the vehicle compartment and the control unit controls operation of the air conditioning unit. The control unit restricts the operation of the air conditioning unit when the remaining battery capacity is less than or equal to a predetermined value. Thus, it is possible to ensure running safety while passenger thermal comfort can be improved. | 08-22-2013 |
20140060796 | AIR CONDITIONER FOR VEHICLE - An air conditioner for a vehicle includes a blower; a heat exchanger that heats the blown air by heat exchanger between blown air and a heat medium, a control device, and an air outlet mode switching device that switches between air outlet modes by switching proportions of air flow blown out from outlets which includes a face air outlet and a foot air outlet, wherein the control device limits the availability factor of the blower based on a temperature of the heat medium; and relaxes limitation on the availability factor of the blower when the air outlet mode is a bi-level mode in which the blown air is blown out from both of the face air outlet and the foot air outlet. | 03-06-2014 |
