20120011869 | VEHICLE AIR-CONDITIONING SYSTEM - A vehicle air-conditioning system ( | 01-19-2012 |
20120193339 | HEATING-MEDIUM HEATING UNIT AND VEHICLE AIR CONDITIONER USING THE SAME - In a heating-medium heating unit equipped with a first heating-medium circulation box and a second heating-medium circulation box which are in close contact with both surfaces of a PTC heater, in which heating-medium circulation passages are formed in the interior, and which are joined to each other in a liquidtight manner, wherein joining surfaces are sealed with liquid gaskets, the heating-medium circulation passages are provided with joining-surface cooling channels that cool the joining surface which is sealed with a liquid gasket and on which the heat from the PTC heater acts. The joining-surface cooling channels are provided at positions closer to the joining surface than to the PTC heater. | 08-02-2012 |
20120234030 | AIR CONDITIONING APPARATUS - Provided is an air conditioning apparatus that is capable of suppressing increases in volume and cost of the apparatus and performing more suitable overheating protection. An electric compressor is an inverter-integrated electric compressor integrally including a compressor, an electric motor that drives the compressor, and an inverter including a temperature sensor that detects the temperature in the vicinity of a semiconductor switching device, wherein a controller estimates a discharge temperature of the compressor on the basis of a correlation of respective pressure loading characteristics for the detected temperature of the inverter, for the rotational speed of the compressor, and for the motive force of the compressor in a refrigerating cycle. | 09-20-2012 |
20130026151 | HEAT-TRANSFER-MEDIUM HEATING APPARATUS AND VEHICLE AIR CONDITIONING APPARATUS USING THE SAME - Provided is a heat-transfer-medium heating apparatus including: a first heat-transfer-medium circulating box and a second heat-transfer-medium circulating box, which are attached to each other in a fluid-tight manner, in which heat-transfer-medium circulating paths are formed therein in close contact with both surfaces of a PTC heater; an electrical-component cooling wall member that is provided in, for example, the first heat-transfer-medium circulating box so as to be located adjacent to the heat-transfer-medium circulating path; and an electrical component that is fixed on the electrical-component cooling wall member, wherein a protruding portion is formed on the surface at the heat-transfer-medium circulating path side of the electrical-component cooling wall member so as to be positioned at exactly behind an installation position of the electrical component and to extend towards the heat-transfer-medium circulating path. | 01-31-2013 |
20130139528 | HEAT-PUMP AUTOMOTIVE AIR CONDITIONER AND DEFROSTING METHOD OF THE HEAT-PUMP AUTOMOTIVE AIR CONDITIONER - A refrigerant cycle ( | 06-06-2013 |
