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 is conducted via a heat exchanger (20) (duct in the ground - pipe in pipe-vacuum - counterflow - heat recuperation system with passive burglary and fire detection equipment) in order to provide cool fresh air in summer and to heat the fresh air in winter. The fresh air and the outgoing air are guided in a counterflow through pipes (36-41) that are inserted into each other to enable useful recovery of the heat energy contained in the outgoing air.
