In addition the system comprises means (78-100) for selectively connecting at least one of the plurality of vehicle components to at least one of the thermal energy distribution paths so as to draw thermal energy from and/or reject thermal energy to said vehicle component or components.

An air conditioning system for motor-vehicles includes a thermally controlled expansion valve unit for regulating the expansion of the fluid upstream of the evaporator, depending upon the temperature downstream of the evaporator. An intermediate heat exchanger provides a heat exchange between the conduit upstream of the evaporator and the conduit downstream of the evaporator. The expansion valve unit is arranged in such a way that its temperature sensor detects a temperature of the fluid along the conduit downstream of the evaporator at a portion of this conduit which is located downstream also with respect to the intermediate heat exchanger. A connecting flange is interposed between the evaporator and the thermally controlled expansion valve unit.

A safety device for a vehicle can include an impulse sensor configured to sense an impact to the vehicle and generate an impulse signal based on the impact, a compressor configured to compress refrigerant for a refrigeration cycle of the vehicle, and a safety valve connected to the compressor and configured to receive the impulse signal from the impulse sensor, and in response to the impulse signal exceeding a predetermined value, open the safety valve to place an inner space of the compressor in communication with an outside of the compressor for discharging the refrigerant outside the vehicle.

A multifunctional expansion valve may include a second exit, and a chamber fluidically-communicating with the first entry, the second entry, the first exit, and the second exit, and a needle valve movably mounted in the chamber of the valve body along up and down directions, wherein the first entry and the first exit are selectively fluidically-communicated to each other and the second entry and the second exit are selectively fluidically-communicated to each other according to a position of the needle valve.

An apparatus for use in venting a compartment in a vehicle includes a housing which at least partially defines an air flow passage. A valve element moves from a closed condition to an open condition to enable air to flow through the air flow passage. The valve element has an inner surface facing the air flow passage when the valve element is in the closed condition. The valve element has an outer surface opposite the inner surface facing away from the air flow passage when the valve element is in the closed condition. A spring wire deflects as the valve element moves from the closed condition toward the open condition and is effective to urge the valve element toward the closed condition. The spring wire extends in a straight line from the housing to the inner surface of the valve element when the valve element is in the closed condition.

A heat medium circulation equipment, a first pump, and a second pump are connected to a first switching valve and a second switching valve. A heater core is connected to at least one of the first switching valve and the second switching valve, and connected to a heat medium circuit. A state, in which the heat medium discharged by a third pump flows into the heater core, is selected by switching of a switching device.

Described herein is a heating and/or air-conditioning device for a motor vehicle, the device including an inlet duct for the supply of fresh air, an air transmission branch, and an air heating branch, both supplied by the inlet duct and communicating with each other via a mixing zone. A butterfly flap is mounted pivotably around a rotation axis located at the mixing zone. The butterfly flap comprises a first wing associated with a first branch and a second wing associated with a second branch, as well as a wing extension elastically hinged to the first wing according to a hinge axis parallel to the rotation axis of the butterfly flap. Within the first branch are arranged abutment formations suitable to be engaged by the wing extension and to induce, during a rotation of the butterfly flap, a rotation of the wing extension with respect to the first wing.

A battery heating device includes: a radiator and a heater core arranged in parallel with each other; a battery temperature adjusting unit for heating a battery with a heat medium; a first branch branching the heat medium between the radiator and the heater core; a first confluence where the heat medium merges; a second branch where the heat medium from a heat emitter is branched to the battery temperature adjustment unit; a second confluence where the heat medium flowing through the battery temperature adjustment unit merges; and a radiator flow rate reducing part arranged in a passage for the heat medium from the first branch or the second branch closer to the radiator to the first confluence or the second confluence closer to the radiator via the radiator.

A reversible refrigeration cycle system is configured to provide heating and cooling to condition passenger air for a vehicle such as, for example, a bus. The reversible refrigeration cycle system includes a storage tank for storing fluid, a compressor, a plurality of coils, and valves for selectively conducting the fluid to the plurality of coils.

A thermal management module includes a component carrier, at least two, typically multiple electrically controllable function components for temperature-controlling at least one vehicle component of a motor vehicle, which are detachably or non-detachably connected to the component carrier, at least one electrical control unit, which for electrically controlling at least two, typically multiple, particularly typically all of the function components include a control electronic system, which via at least one electrical control line path and/or via a component field bus is electrically connected to the respective function component and arranged in a housing of the control unit, wherein the housing of the control unit is detachably or non-detachably fastened to the component carrier and/or to at least one of the function components.
