AIR CONDITIONING SYSTEM FOR BUILDINGS AND AIR-CONDITIONED BUILDING, ESPECIALLY A ZERO ENERGY HOUSE

摘要

The fresh air, outgoing air or vacuum air system isconducted via a heat exchanger (20) (duct in the ground - pipein pipe-vacuum - counterflow - heat recuperation system withpassive burglary and fire detection equipment) in order toprovide cool fresh air in summer and to heat the fresh air inwinter. The fresh air and the outgoing air are guided in acounterflow through pipes (36-41) that are inserted into eachother to enable useful recovery of the heat energy contained inthe outgoing air.
