Abstract: A housing arrangement has a blower motor including a rotation shaft that traverses through an underside and a topside of the blower motor, the rotation shaft being configured to mount a fan impeller thereupon, a first housing part that receives the blower motor, a second housing part that covers the blower motor received in the first housing part, a first decoupling unit arranged circumferentially between the underside of the blower motor and an inner bottom of the first housing part, and a second decoupling unit arranged circumferentially between the topside of the blower motor and an inner surface of the second housing part. Here, the spring stiffness of the first and the second decoupling units are substantially constant in an axial direction, a radial direction, or a normal direction.

Abstract: A heat exchange system includes a dual expansion valve for a refrigerant cycle of a vehicle that includes a first inlet and a first outlet, a first flow restriction mechanism including a movable first valve element, by which a first refrigerant stream flowing through a first passage from the first inlet to the first out let can be controlled, a second inlet and a second outlet, a second flow restriction mechanism including a movable second valve element, by which a second refrigerant stream flowing through a second passage from the second inlet to the second outlet can be controlled, a control member for jointly moving the first valve member and the second valve member, a sensing element for sensing a temperature, and a valve driving member that is configured to drive the control member according to the sensed temperature.

Abstract: An arrangement for de-icing a heat exchanger includes an air guiding housing and at least one fan. The air guiding housing is configured to take in an air from an outside of a motor vehicle through an inlet opening and to discharge the air from an outlet opening. The fan is positioned between the inlet opening and the outlet opening inside the air guiding housing and is configured to circulate the air in the air guiding housing. The heat exchanger is positioned between the inlet opening and the outlet opening inside the air guiding housing and allows the air to pass therethrough, thereby being configured to cool the air. The inlet opening and the outlet opening each are configured to be closed. The air guiding housing is configured to cause a circulation flow therein when the fan is operated while the inlet opening and the outlet opening are closed.

Abstract: Within a warm circuit, a first heat exchanger is in heat exchanging contact with a heat source. A second heat exchanger is in heat exchanging contact with a space to be heated. Within a cold circuit, a third heat exchanger is in heat exchanging contact with a heat sink. A fourth heat exchanger is in contact with an external region. A valve device is to connect the warm circuit with the cold circuit. An actuating device is to switch the fourth heat exchanger into a de-icing mode. The valve device enables mixing of coolant at least partially from a portion of the warm circuit into the cold circuit.

Abstract: An air conditioner for a vehicle includes a housing for defining an air passage, and the air passage has a main passage and first and second separate passages branched from the main passage. The first separate passage is provided for leading air from the main passage to a front area of a passenger compartment, and the second separate passage is provided for leading air from the main passage to a rear area of the passenger compartment. Furthermore, an evaporator is disposed in the main passage of the housing, and a heat exchanger is disposed in the main passage at a downstream air side of the evaporator in a part area of the main passage. In the air conditioner, a control member is provided to adjust an air flow from the evaporator into the first separate passage and an air flow from the heating heat exchanger into the first separate passage.
