Abstract:
A ventilation controlling apparatus for feeding windshield defrost outlets and side window demist outlets in motor vehicles with one or more air passages and respective doors for each outlet. The apparatus supports a mode in which the demist door opens up to a predefined angle without the defrost door opening, too, with the predefined angle depending on the design of a cam attached to the demist door and a pin engaged with that cam and attached to the defrost door.
Abstract:
The invention relates to an air-conditioning system (1) for a vehicle driven by a motor (16), having a refrigerant circuit (5) with a plurality of heat exchangers (2, 11) through which a refrigerant can be conducted for an exchange of heat with the air which flows through them, and having a heat pump heat exchanger (9) in which an exchange of heat with a coolant circuit (6), in which at least one coolant cooler (19) is arranged, takes place, with it being possible for the coolant cooler (19), in the heating mode, to be used as a heat exchanger for absorbing heat from the environment, and with the coolant cooler (19) being connected in series downstream of the heat pump heat exchanger (9) in the coolant circuit (6), and to a method for regulating an air-conditioning system (1) of said type.
Abstract:
The disclosed air-conditioning system for a vehicle driven by a motor, has a refrigerant circuit with a plurality of heat exchangers through which a refrigerant can be conducted for an exchange of heat with the air which flows through them, and has a heat pump heat exchanger in which an exchange of heat with a coolant circuit, in which at least one coolant cooler is arranged, takes place. It is possible for the coolant cooler, in the heating mode, to be used as a heat exchanger for absorbing heat from the environment. It is possible for the coolant cooler to be connected in series downstream of the heat pump heat exchanger in the coolant circuit A method for regulating such an air-conditioning system is also disclosed.
Abstract:
A vehicle having an HVAC system with a particular ventilation housing design and method for making the same are described. The ventilation housing has a common mode door for defrost and floor panels and allows efficient use of components to provide effective operation in bi-level and other modes. In bi-level mode, the mode doors can be operated to form flow path such that floor outlet is virtually on the upstream side of the panel outlet.
Abstract:
The invention relates to an air-conditioning system for a motor-driven vehicle, having a refrigerant circuit (20) with a plurality of heat exchangers (4, 24) through which a refrigerant can be conducted for an exchange of heat with the air which flows through them, with it being possible for the heat exchangers (4, 24) to be operated as heaters or as evaporators as a function of the operating state of the air-conditioning system, and at least one third heat exchanger (16) is provided in the refrigerant circuit (20), which third heat exchanger (16) serves for an exchange of heat with a coolant circuit (13) which is formed separately from the refrigerant circuit (20). The vehicle can be both a motor vehicle and also a fuel-cell-driven vehicle.

Abstract:
A holding device for a motor, particularly for an electric fan wheel motor of a heating or air condition system of a motor vehicle, having an adapter which can be fixed on an exterior motor component and surrounds it at least partially on the circumference side, as well as having a motor holder connected with the adapter and having at least one vibration-uncoupling supporting element. According to the invention, primarily axially stressed supporting elements are provided between axially spaced parts of the adapter, on the one hand, and of the motor holder, on the other hand, or between the exterior motor component and a bottom surface of a cup-shaped adapter which can be fixed thereto, or such supporting elements which are mounted radially between motor holder fastening arms and adapter holding fingers, while being fastened on one part and engaging form-lockingly in receiving pockets on the other part. The holding device may be used, for example, for holding a fan motor of a motor vehicle air-conditioning system with a low vibration transmission and a reduced contribution to the noise development caused by the motor holder.
