The device operates as follows. The room air of the passenger compartment or cabin of the vehicle, tractor or other vehicle is supplied by the fan 4 to the heat exchanger 9 where it is cooled due to adiabatic evaporation of water from the plates and flows in the catchment area, reducing the temperature of indoor air, providing dushiruumi impact.

Solve also the problem of creating a mini-air which is created when the heating causes the symptoms of unhealthy premises" (adopted by the international terminology). Due to the dry air causes serious diseases: headaches, fatigue, General malaise, nausea, lesions of the mucous membranes of the nose, eyes and throat, that is, there are so-called winter colds: cough, sore throat, pneumonia, etc.
