A device for temperature control for a motor vehicle, includes a diffractive optical element disposed on a surface of the motor vehicle, and a radiator. The diffractive optical element couples in incident radiation and conducts the coupled-in incident radiation away from an area of the motor vehicle to be cooled. The radiator includes an absorber to absorb the coupled-in incident radiation which is conducted to the absorber from the diffractive optical element. The radiator releases energy based on the coupled-in incident radiation absorbed by the absorber.

Certain disclosed embodiments pertain to controlling temperature in a passenger compartment of a vehicle. For example, a temperature control system (TCS) can include an air channel configured to deliver airflow to the passenger compartment of the vehicle. The TCS can include a one thermal energy source and a heat transfer device connected to the air channel. A first fluid circuit can circulate coolant to the thermal energy source and a thermoelectric device (TED). A second fluid circuit can circulate coolant to the TED and the heat transfer device. A bypass circuit can connect the thermal energy source to the heat transfer device. An actuator can cause coolant to circulate selectively in either the bypass circuit or the first fluid circuit and the second fluid circuit. A control device can operate the actuator when it is determined that the thermal energy source is ready to provide heat to the airflow.

The seat air conditioner configured to supply conditioning air to a seat in a vehicle cabin includes a refrigeration cycle, an air blower, and a conditioning air supply unit. The refrigeration cycle includes a compressor that compresses and discharges a refrigerant, a heat emitting portion that emits heat of the refrigerant discharged from the compressor to generate a warm air, a decompressor that decompresses the refrigerant flowing out of the heat emitting portion, and a heat absorbing portion that evaporates the refrigerant decompressed by the decompressor to generate a cold air. The air blower blows air to exchange heat with the refrigerant. The conditioning air supply unit supplies each of the warm air generated by the heat emitting portion and the cold air generated by the heat absorbing portion as the conditioning air to the seat.
