Evaporative cooling for OptEvent

JS Humidifiers’ HumEvap MC3 evaporative humidifier has been selected by AHS (Air Handling Systems) to provide evaporative cooling in the innovative OptEvent air handling unit. The humidifier cools the return air with low energy cold water humidification in this packaged heat recovery system that has been independently verified by BSRIA.

Working on behalf of a leading and progressive London children’s hospital, AHS was tasked to develop a packaged liquid-coupled heat recovery system to meet the hospital’s demands for hygiene, comfort and energy efficiency. The result was OptEvent which packages a HumEvap MC3 with an AHU and includes a pre-programmed ECM (Energy Control Module) that constantly ensures the minimum amount of energy is used to meet the air requirements.

As return air passes through the HumEvap MC3, moisture is absorbed by the air and it is adiabatically cooled to as near 16°C as possible. This humid cool air is then used to chill the incoming fresh air with the use of a heat recovery system. By pre-cooling the incoming fresh air in this way substantial savings in energy costs can be achieved compared to compressor drive technology.
