BITZER compressor map: where the chiller operates
Evaporating vs. condensing temperature. Contours = cooling capacity at 100 % slide from the BITZER EN 12900 polynomial (CSH8583-125Y, R134a). Shaded = calculated envelope. Dot = live operating point, trail = last 10 min.

Efficiency: COP vs. load
Expected COP from BITZER data at the live evaporating and condensing temperatures across the slide range, and the measured COP.

Chiller circuit
Refrigerant circuit and water loops with live sensor values. Red = beyond the twin's alarm limit.
