摘要

Invention Patent: B "AIR CONDITIONING OF BUILDINGS AND BUILDING EQUIPPED WITH AIR CONDITIONING, IN PARTICULARLY A ZERO ENERGY HOUSE" D. Fresh air, exhaust air or vacuum system is driven by a heat exchanger (20) (duct on the floor - tube in the vacuum tube - counterflow - heat recovery system with passive break-in and fire detection equipment) in order to provide cool fresh air in summer and to warm fresh air in winter. The fresh air and the exhaust air are guided in a counterflow by the tubes (36-41) which are inserted into each other to allow usable recovery of the heating energy contained in the exhaust air.
