20110016896 | Air conditioner for vehicle with heat pump cycle - An air conditioner for a vehicle includes a vapor compression refrigeration cycle switchable between a heat pump cycle and a cooler cycle, a heat core configured to heat air to be blown into a vehicle compartment by using coolant of an engine of the vehicle as a heat source, and a controller configured to control operation of the vapor compression refrigeration cycle. The controller controls the vapor compression refrigeration cycle to be operated as the cooler cycle so as to perform a defrosting control of the outdoor heat exchanger, and outputs an operation request signal to the engine, when the controller determines that the outdoor heat exchanger is frosted. | 01-27-2011 |
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 |
20120297805 | COOLING SYSTEM FOR BATTERY - A cooling system of a battery which efficiently cools a high voltage battery which is mounted in an electric vehicle or a hybrid vehicle so as to maintain battery performance by using a refrigeration cycle of an air-conditioning system, which is provided with an electric compressor, outside heat exchanger, inside heat exchanger, and a control device. A refrigerant path of the air-conditioning system for running refrigerant is provided with a branch path having a heat exchanger which bypasses the inside heat exchanger, a medium path connected to the heat exchanger runs another refrigerant for cooling the battery, control valves are provided which adjust the amounts of the refrigerant which flows to the refrigerant path and the branch path, and, when the control valves run the refrigerant to both the refrigerant path and the branch path, the control device increases the speed of the electric compressor. | 11-29-2012 |
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 |
20140102666 | AIR CONDITIONER FOR VEHICLE - An air conditioner for a vehicle includes a blower that generates blown air; a heating heat exchanger that heats the blown air by heat exchange between the blown air and a heat medium; a target temperature setup device that sets a target temperature for a passenger compartment in accordance with an operation performed by an occupant; and a control device that determines the availability factor of the blower in accordance with the temperature of the heat medium wherein the control device increases the availability factor of the blower as the target temperature increases. | 04-17-2014 |
20140144998 | AIR CONDITIONER FOR VEHICLE - An air conditioner for a vehicle having an electric motor for traveling and an internal combustion engine as driving sources for outputting a driving force for causing the vehicle to travel, the air conditioner including: a heating section that heats blown air to be blown into a vehicle interior by using a coolant of the internal combustion engine as a heat source; a request signal output section that outputs a request signal to a driving force control section in heating the vehicle interior, the driving force control section controlling an operation of the internal combustion engine, the request signal causing the internal combustion engine to operate until a temperature of the coolant reaches an upper limit temperature; and a suppression section for suppressing output of the request signal from the request signal output section until a predetermined condition is satisfied after startup of the vehicle. | 05-29-2014 |
