FIELD: transport.
SUBSTANCE: invention relates to automotive industry. Proposed system comprises heater housing and fan housing communicated via air duct with the former. Heater chamber is communicated via developed system of openings and ducts with zones of passenger compartment. Besides, heat-and-vent system includes one structural noise absorbing element. The latter is composed of noise absorbing module including connection structural shell. Said shell is mounted in limited local perforated zone on the wall of structural and/or air conduit element and filled with isolated crushed porous arbitrary-shape noise absorbing fragments. Said fragments are arbitrarily fitted inside said shell to stay in contact with each other. Said fragments represents the products of secondary recycling of porous noise absorbing materials, parts and assemblies of noise absorbing packs.
EFFECT: higher efficiency.
