CORRECTION FACTORS FOR GLYCOL

(Equivalent water ¯ow method for all 42 Series Models)

This method allows you to calculate cooling and heating performance without adjusting capacities for glycol concentration.

After completing the standard selection procedure including water ¯ow rates, use the correction multiplier shown below to determine new (equivalent) ¯ow rates required for the speci®ed glycol concentration.

EXAMPLE:

COOLING PERFORMANCE REQUIRES 3.0 gpm of 100% WATER.

What ¯ow rate of 30% glycol by voume will be required to match the cooling performance? Referring to the chart above, you will note that the cooling ¯ow rate multiplier for 30% glycol is 1.14.

100% WATER (3.0 gpm) x 1.14 = 3.42 gpm of 30% GLYCOL (EQUIVALENT FLOW RATE)

What will the new pressure drop be for 3.42 gpm of 30% glycol? Referring to the chart above, you will note that the cooling pressure drop multiplier for 30% glycol is 1.27.

(A)Obtain pressure drop for 3.42 gpm of 100% water.

(B)Multiply (A) times 1.27 to obtain pressure drop for 3.42 gpm of 30% glycol.
