The cooling of rooms is limited in terms of thermal comfort for people in the occupied zone. High cooling capacity means high volume flows and low supply air temperatures at the air outlet of the units. In the occupied zone, however, this means draughts, the most common cause of discomfort.
In terms of flow technology, it must now be possible to reduce both high air velocities and low temperatures on the short path between the appliance outlet and the occupied zone by mixing with warm ambient air and increasing turbulence in the best possible way. Optimization using suitable air diffusers with a high inductance and maximizing the mixing ratio is a path that has been consistently pursued for a hundred years. The physical limits are largely exhausted with these systems.
However, one premise of this optimization was always a stationary flow, i.e. a continuous supply air volume flow. This makes sense against the background of fans as flow machines and the requirement for consistent acoustics. LTG began researching and using transient, transient systems in room air conditioning 20 years ago.
It quickly became apparent that a pulsating flow, e.g. by using vortices that transport cold supply air along the ceiling, or by introducing supply air cyclically, can significantly increase thermal comfort. This results in stable flow effects that can be controlled with the new degree of freedom “cycle duration or frequency”. Of course, no compromises are made in terms of acoustics and energy efficiency, and new benchmarks are set here.
