Hi,

I am doing some work looking at using more night-time cooling at an industrial facility (refrigeration plant cools a brine solution which is then passed through some tank jackets to cool tanks). The idea is to use cheaper off-peak power and also to take advantage of increased refigeration efficiency at the lower ambient temperatures. The system has an evaporative condenser and refrigerant control is by a high side float.

I am relatively new to this and I wanted to verify that with this high side float control, I would get lower discharge pressures as the ambient temperature decreased and hence improved refrigeration plant efficiency.

Thanks for your help. I appreciate it.

Cheers
