In the transitional and winter period is considered the free cooling - freecooling using cold air from the compressor without switching using external coolers, circulation pumps and plate heat exchanger.
These include direct expansion systems that are able to operate at high return-air temperatures, suitable for the increased temperatures within which IT equipment works; chilled water systems that maximize freecooling operation all year round and include a chilled water floor mount range and freecooling chillers; as well as an adiabatic freecooling chiller (Liebert AFC), which combines 3 cooling technologies (adiabatic cooling, freecooling, and mechanical cooling) in a single unit and is capable of achieving a partial power usage effectiveness (pPUE) of 1.
