Eq. 49
The 3 rd level is also focusing on the water consumption for cold production. The water
consumption of the wet cooling tower and the DEC system is evaluated in terms of:
- Cooling tower water consumption per kWh dissipated heat
ACM _ water

On the other hand the electrical consumption related to the treatment of the water is
calculated in terms of:
- Electricity consumption for water treatment per liter treated water in SHDC systems
