A heating system for a vehicle includes: a heater for non-contact heating that emits radiation heat by heat supplied from its heat generating part, which generates heat upon energization, to give warmth to an occupant in a state where a body of the occupant is not in contact with the heater; a heater for contact heating that generates heat upon energization to give warmth to the occupant in a state where the body of the occupant is in contact with the heater; and a control device that controls operations of the heater for contact heating and the heater for non-contact heating. The control device adjusts a heating output provided by the heater for contact heating and a heating output provided by the heater for non-contact heating, and controls the operations. Therefore, the occupant can enjoy a sense of heating that is not stereotypical, and achieve energy saving.

A battery powered auxiliary HVAC system designed to heat and cool at least a sleeper compartment of a vehicle such as a truck with a management system for conserving battery power. The management system includes a processor connected to temperature sensors, motion sensors, occupancy sensors, etc. for controlling a variable speed compressor, evaporator fan and condenser fan. A fuel fired heater is positioned between an evaporator coil in the inlet of an enclosure and the evaporator fan in an outlet of the enclosure such that air flow passes around the heater. The power electronics to operate the system may be actively cooled by connection tubing providing a heat sink between an evaporator outlet and a compressor inlet.

A method for transporting heat-sensitive products in a refrigerated truck that includes at least one product storage chamber, a cryogenic fluid reserve, and a main heat exchanger system for circulation of the cryogenic fluid therethrough. The main heat exchange system includes walls across which heat may be exchanged, one or more cold-producing blowers for bringing air inside the chamber into contact with the walls, and a heating system for heating air inside at least one of the chambers. Upon the occurrence of one or more events, heated air is blown into an intake side of the cold-producing blower(s).

A radiation heating device includes: a planar heat generation layer; a heat generation portion that is provided in the heat generation layer and that generates heat by energization; a plurality of heat radiation portions that are disposed in the heat generation layer and that radiate heat transferred from the heat generation portion; a low heat conduction portion that is provided around each of the heat radiation portions and that has a lower heat conductivity than the heat radiation portions; and a contact detection unit that detects contact of an object with the heat generation layer. The radiation heating device further includes an energization amount decrease unit that decreases an energization amount of the heat generation portion when the contact detection unit detects the contact of the object with the heat generation layer.

An auxiliary heater with a casing enclosing internal components which components include a heat exchanger separate from and outside the coolant tank and wherein two coolant loops each have their own coolant pumps and wherein a potable water loop exchanges heat with coolant within the heat exchanger. A control circuit provides enhanced coolant flow through the heat exchanger when the call for hot water is significant without significantly reducing the temperature of the hot water being used. A level switch within the coolant tank prevents coolant pumps from running without pump coolant and a filling and air purging operation improves the initial filling operation of the auxiliary heater with coolant and also prevents the coolant pump from running dry. A user switch may dedicate the hot coolant from the coolant tank to either the production of hot potable water or it may share both hot water and space heating.

A remote-controlled automobile heater system includes a housing having a magnet disposed on the top-side that is able to secure the remote-controlled automobile heater system to the interior of the cab of an automobile. The housing includes a heating element and a mechanical fan that blows air across the heating element to create convective heat that disperses within the cab of the automobile. The remote-controlled automobile heater system further includes a transmitter capable of activating the heating element and the mechanical fan from a distance. The remote-controlled automobile heater system is useful for attaching to the interior cab of an automobile for pre-heating the automobile cab before driving.

Disclosed herein is a headrest air-conditioning device for vehicles, wherein a heater plate with planar heating elements on both sides thereof is installed inside a casing, and the heater plate divides the interior space of the casing to form an inflow passage and an outflow passage. Accordingly, it is possible to effectively heat air with low power and to reduce flow resistance and thus power consumption.

An interior lining element, for example for a passenger compartment of a vehicle, including a single-layer or multilayer decorative covering, the front side of which faces the passenger compartment and delimits the latter physically and, via the back side thereof, is in thermally conductive contact with a printed heater, where the heater has a plurality of flat resistance elements and at least two feed lines which are electrically highly conductive as compared with the resistance elements and via which the resistance elements can be looped into an electric circuit, and where in contact-making regions of the resistance elements and of the feed lines, one feed line and one resistance element are each printed overlapping each other.

An air deflector bar extends parallel to an upper edge of a front windscreen of a motor vehicle. The air deflector bar includes an air deflection channel that extends along its length. The air deflection channel is concavely delimited in cross section by means of a first side that butts against the front windscreen and a second side that is connected to the first side and is at a distance from the first side. The inner surface of the second side of the air deflector bar is oriented toward an edge of a dashboard of the motor vehicle, which edge delimits the dashboard toward a passenger interior.

The invention relates to a multi-zone air conditioning system for vehicles (1) with several air conditioning zones (2), in particular for buses, characterized thereby that an air temperature control unit (3) is implemented to generate simultaneously warm air and cold air, wherein the cold air across a cold air duct (5) and the warm air across a warm air duct (6) extend separated from one another as a double conduit over the length of the vehicle (1) and that decentralized air mixing units (4) with at least one air outlet (20) are disposed along the double conduit and that the air outlets (20) are assigned to the air conditioning zones (2) of the vehicle (1).
