A cabin heater for a vehicle includes a frame with spaced apart longitudinal supports to locate a common electrical return and a power input. Pluralities of heating units extend between the supports and attach to the return and input. Each unit has a ceramic heater and one or more positive temperature coefficient (PTC) elements. The ceramic heater quickly and directly heats air and helps lower the inrush current of each PTC element upon initial powering. The power input also includes conductive rails spaced apart and electrically isolated from one another to individually supply power to either the ceramic heater or the PTC elements, but not both. Conductive extensions pass through the rails and fold into contact to power either the heater or the PTC elements. The electrical return commonly attaches the PTC elements and the heater, including a spring connection.

A heat generator using a Carbon Nano Tube (CNT) composite material includes: an outer electrode part; an inner electrode part which faces the outer electrode part and is spaced apart from the outer electrode part at a predetermined distance; a connection part which connects the outer electrode part with the inner electrode part; and a bracket part which is disposed in the outer electrode part and the inner electrode part including the connection part to shield the outer electrode part, the inner electrode part and the connection part from each other. A surface of the connection part does not face directly the outer electrode part and the inner electrode part. The outer electrode part and the inner electrode part include electrodes having polarities different from each other.

Disclosed is a heating device comprising a plate-shaped ceramic PTC resistor having a thickness, a front side, a back side and narrow sides, wherein the distance from the front side to the back side equals the thickness, and a first contact element and a second contact element, which are electrically contacting the PTC resistor. The PTC resistor is electrically contacted by the contact elements on opposite narrow sides.

Methods and systems are provided for heat sanitizing a vehicle. In one example, a method may include, responsive to receiving a request for cleaning an interior of a vehicle, adjusting a position of a sun shade based on at least one of an ambient temperature outside of the vehicle and a sun load of the vehicle, and operating a heating, ventilation, and air-conditioning (HVAC) system to heat the interior above an upper threshold temperature for a first threshold duration. In this way, the HVAC system may be advantageously used to expose the vehicle interior to temperatures that kill or inactive microbes.

A vehicle air conditioner, including a first duct having a first ventilation opening that is disposed on first side in a width direction of a seat provided in a vehicle, a second duct having a second ventilation opening that is disposed on second side in the width direction of the seat, the second side being opposite side of the first side, and a third duct having a third ventilation opening that is disposed in front of the seat.

A vehicle heat exchange system includes a coolant circulation circuit, a refrigerant circulation circuit, a pump controller, and a detector. In the coolant circulation circuit, a coolant is circulated. In the refrigerant circulation circuit, a refrigerant is circulated. The pump controller controls a flow rate of the coolant. The detector detects a liquid temperature of the coolant before cooling an electric unit. The coolant circulation circuit includes a radiator that dissipates heat of the coolant, having cooled the electric unit. The refrigerant circulation circuit includes an exterior heat, exchanger in rear of the radiator. The exterior heat exchanger causes the refrigerant to absorb heat from external air. When the detected liquid temperature is equal to or higher than a predetermined temperature, the pump controller maintains or increases the flow rate. When the detected liquid temperature is lower than the predetermined temperature, the pump controller decreases the flow rate.

The air-conditioning system includes a blower for generating an air flow, a heating device for heating the air flow, and a ducting system that divides the air flow downstream of the heating device over at least two part air flows and supplies the at least two part air flows via associated ducts to associated air outlets, through which the part air flows exit into the vehicle interior. The heating device includes at least two separate regions each with at least one electric heating element that is separately controllable via a control device. The at least two separate regions are each permanently assigned one of the associated ducts of the ducting system.
