This assessment consisted of a side-by-side comparison of two otherwise nearly-identical milk chillers; one with a finned-tube air-cooled condenser with fan cycling on pressure switches, and the other system with a microchannel air-cooled condenser. The project incrementally assessed the impact of the microchannel condenser on system performance with the same control strategy as the replaced condenser, and then with floating head pressure and variable-setpoint (e.g. drybulb-following) control.
