FIELD: heating systems, namely use of air flows for screening, for example air curtains.
SUBSTANCE: apparatus includes blower for blowing screening air flow; unit for directing screening air flow and temperature regulator of screening air flow. Novelty is that temperature regulator includes at least one module having heat source and(or) heat absorber; blower of heated or cooled air flow; units for power supply, controlling and mounting, operating autonomously and providing possibility for changing zone of influence of heated or cooled air flow upon screening air flow. Invention provides possibility for modifying preliminarily mounted air curtain apparatuses.
EFFECT: enhanced efficiency, power saving, possibility for changing designed power of different air curtains, reduced time lag of apparatus.
