Conventional rooftop units at best utilise minimum fresh air recirculation to improve the summer peak ambient operation but the heat rejection system still relies on peak ambient air. If the hidden evaporative energy of water is introduced as part of an adiabatic system, the overall energy consumption can be significantly reduced.

EcoComfort Ô units optimise this hidden energy both directly and indirectly via a heat recovery unit between the supply and extract air streams. The overall C.O.P. is further improved by placing the mechanical refrigeration condenser within the extract air stream after the adiabatic indirect cooling operation which provides lower air-on temperatures, hence, lower condensing pressures.
