FIG. 15 – FLOW RATE AND PRESSURE DROP CHARTS
GLYCOL CORRECTION FACTORS
The evaporator is designed in accordance with
When using glycol solutions, pressure drops are higher than with water (see correction factors to be applied when using glycol solutions).
A = Correction Factor
B = Mean Temperature through Evaporator (°C) C = Concentration W/W (%)
Excessive flow, above the max GPM, will damage the evaporator.
GLYCOL CORRECTION EXAMPLE: (With YCAS0140)
•RWT = 36°F LWT = 28°F
•Average Water Temperature = 32°F (= 0°C)
•For 30% Propylene Glycol: From Graph, Find Correction Factor =
1.3@ 0°C and 30%
•Actual Measured ∆P = 12' H20
•Corrected ∆P = 12'/1.3 = 9.2' H20
•From Flow Rate and Pressure Drop Chart, locate flow @ 9.2' ≈ 300 GPM
