This article surveys a little known approach to two simultaneously requested but mutually opposed requirements on thermal ditions in buildings. It is the growing demand of internal comfort -while the other is decrease of costs and energy consumption. The internal conditions are controlled by terminal units located and adjusted at the points of conditioned air delivery. Author’s terminal units achieve both goals by having no moving parts. Advantages are low cost, robustness and long operating life without maintenance. Capability to switch the air flows at a high frequency without wear opens new ways to control, such as the flow pulse width modulation. The fast switching also makes possible small size of regenerative heat exchangers, keeping inside the building the heat extracted prior its departure from the removed contaminated air.
