COMFORTABLE TEMPERATURE CONTROL APPARATUS USING HEAT FLUX SENSOR

摘要

A comfortable temperature control apparatus for a vehicle includes a temperature-change element that changes a temperature by being energized; a heat flux sensor outputting a sensor signal corresponding to a heat flux; a heat diffusion layer disposed on the heat flux sensor; and a control unit that energizes the temperature-change element so as to adjust its temperature. In a seat provided in the vehicle cabin, a cover surface side contacting a passenger, the heat diffusion layer, the heat flux sensor and the temperature-change element are arranged in this order. The heat flux sensor outputs the sensor signal to the control unit, the sensor signal corresponding to the heat flux between the cover surface and the temperature-change element. The control unit adjusts an energization of the temperature-change element, based on the sensor signal, such that the heat flux between the cover surface and the temperature-change element is a predetermined value.

1. A comfortable temperature control apparatus used for a vehicle, the apparatus comprising:
a temperature-change element that changes a temperature thereof by being energized; a heat flux sensor provided on the temperature-change element, outputting a sensor signal corresponding to a heat flux; a heat diffusion layer disposed at an opposite side of a portion contacting the temperature-change element in the heat flux sensor; and a control unit that energizes the temperature-change element so as to adjust the temperature of the temperature-change element, wherein in a seat provided in a vehicle cabin, a cover surface side in contact with a passenger being seated, the heat diffusion layer, the heat flux sensor and the temperature-change element are arranged in this order; the heat flux sensor outputs the sensor signal corresponding to the heat flux between the cover surface and the temperature-change element; and the control unit adjusts an energization of the temperature-change element, based on the sensor signal outputted by the heat flux sensor, such that the heat flux between the cover surface and the temperature-change element is a predetermined value.
