At a wwtp, we will be installing a new cogeneration plant and adsorption chiller. Because adsorption chillers don't com in abritrary sizes, we may have 10 or 20 extra kW cooling power (in the form of cold water, ~ 5°C/15°C).
Now the plant operator has the idea to cool the air inflow into the blower station - the rationale beeing the blowers need cooling anyway & that the blowers are more efficient when working on cooler air.
Has anyone ever done this? Does it make sense from a process standpoint? The electrical power uptake of the combined blowers is up to 65kW (actually measured, not nameplate capacity)
tbh I don't know the exact airflow regime of the blower station - the blowers draw from the room, there's no extra ducts for cooling air, I presume the room has forced ventilation.
Even if the idea makes sense from a process perspective, the installation will be a hassle. The operators idea was to use the heating network pipes for cooling water during the summer, I have my doubts this is really feasible but I havent put much thought into it yet.
I'm of two minds about this: On one hand, the idea is intriguing and I'd like to at least investigate the possibility, OTOH this is no project where I can afford to sink too much time into any dead ends.
