The Water Cooled–Simple chiller uses Entering Condenser Temperature in the curves while the Water Cooled–Detailed chiller uses Leaving Condenser Temperature in the curves.
Capacity Curve
This biquadratic curve shows the percentage of full cooling capacity as a function of the condenser fluid temperature and the leaving chilled water temperature. Inputs consists of two independent variables, six coefficients, and min and max values for each of the independent variables. The equation for the capacity curve is:
Where:
Z = Ice Making Capacity
C1 to C6 = coefficients
X = Condenser temperature
Y = Full load capacity
The curve has the following fields:
|
X Axis:
|
Condenser fluid temperature (°F, °C)
|
|
Y Axis:
|
Cooling Capacity (%)
|
|
Tchw,l Min / Max:
|
Minimum and maximum temperature values (°F, °C) for the Chilled water leaving temperature variable. These values determine the three chilled water temperatures plotted, one is the maximum, one is the minimum and the last one is the midpoint between them
|
|
Tcond,e Min/Max or Tcond,l Min/Max:
|
Minimum and Maximum temperature values (°F, °C) for the Condenser Temperature variable on the X axis. E is for entering, L is for leaving condenser water temperature.
