Free Cooling

Wall-Air Evolution with Direct Free Cooling

Up to 84 % savings on running costs thanks to Mixed and Free Cooling modes

Free Cooling mode

In many base stations, comfort air conditioning units without Free Cooling mode are still used today for air conditioning, with high energy consumption as the result. STULZ Wall-Air Evolution units exploit the potential of Free Cooling and slash running costs.

 

Mixed mode

Wall-Air Evolution units feature Mixed mode. If the outside temperature exceeds a given threshold, Free Cooling alone is no longer sufficient. Then, in Mixed mode, the runtimes of the compressor are kept to a minimum by the simultaneous use of Free Cooling and compressor cooling. In this way, depending on the local temperature profile, annual energy costs can be cut by a further 10 %. Further potential savings are achieved by the air conditioning unit working in partial load mode.
