Optimization of the refrigeration plants operation

[Segei]

The thing i found from experience, the weather changes everyday so does you running temps they change with ambient and humidity, so do the same with refrigeration components CONTROLS, VFD'S and so on its only logic dont you guys think so?

When the weather change operating of evaporative condensers will change.Optimum set point should be readjusted. For example. Optimum wet bulb approach is 10degF. During the day wet bulb temp. is 75 degF so optimum head pressure will be 75+10=85degF or 150psig. During the night wet bulb drop to 60F and optimum head pressure will be 60+10=70F or 115psig. Capacity of evaporative condensers should be readjusted.
