An HVAC system for a motor vehicle includes a filter that absorbs odors and gases in a cabin of the motor vehicle and desorbs the odors and gases when heated, and a heater that is turned on to heat the filter during cool ambient conditions. The heater is turned off during warm ambient conditions and warm ambient air is utilized to heat the filter. The desorbed odors and gases are purged from the cabin of the motor vehicle.

A sample concentrator tube having a heat-resistant planar heating element adhered thereto, an analysis device comprising the same, and an analysis method using the same, according to the present invention, have an effect capable of precisely controlling the temperature by uniformly and rapidly heating the sample concentrator tube to a target temperature for desorption, and capable of almost simultaneously desorbing an adsorbed sample in any part of an adsorbent by minimizing a local temperature difference of the adsorbent in the tube. In addition, it is possible to minimize chemical noise by preventing thermal denaturation of the adsorbent caused by over-heating, and there is an advantage of excellent reproducibility as well as an effect of being inexpensive, economical, and excellent in energy efficiency.
