OXYCOM heat exchanger on display .
A satisfying conclusion .
system to mix the outside air with the indoor heat and provide a more comfortable airflow while saving energy .
As for the indirect path , the system includes ventilators that work in conjunction with a panel that contains the necessary film material . The system also includes a tank that holds the water , which is mixed with evaporate and fresh water in a cycle . In the event of a power outage or shutdown , the drains automatically
open to allow the water to flow out . The water inside the system remains , and when the system restarts , it will require water again . Calculations are done with weather data from the past , taking into account the worst conditions to ensure optimal performance .
The calculation takes into account the internal and external heat loads to determine the appropriate supply temperature . In some cases , a DX system may be necessary as a backup to ensure specific temperature requirements are met . The calculation also considers factors such as airflow , air changes and the comfort zone within the facility .
The outcome of the calculation provides information on the heat load , including the contributions from external factors such as sunlight . Water consumption is also calculated based on evaporation and drainage , considering water quality . The results can be used to determine the optimal temperature settings and the number of units required . Additionally , the calculation provides insights into the cooling hours and energy usage during different times of the day .
Overall , free cooling in data centres offers significant energy savings and can be optimised based on specific requirements and conditions . RACA
