  1. The water flow rates indicated are maximum for the indicated model number. The actual flow is determined by the size of the flow control valve used in the assembly. Available flow rates for each size are as indicated below:

    Size 02 GPM = 0.33, 0.5, 0.67, 1.0, 1.33, 1.67, or 2.0
    Size 06 GPM = 2.33, 2.5, 2.67, 3.0, 3.33, 3.5, 4.0, 4.67, 5.0, or 6.0
    Size 12 GPM = 6.67, 7.33, 8.0, 8.67, 9.33, 10.0, 10.67, 11.33, or 12.0
    Size 14 GPM = 13.0, 13.33, 14.0, 14.67, 15.0, or 16.0
    Size 21 GPM = 17.0, 18.0, 19.0, 20.0, 21.0, or 22.0
    Size 30 GPM = 24.0, 26.0, 28.0, 30.0, 32.0, 34.0, or 36.0

  2. Specify hot water connection size. The hot water flow rate can be no greater than the recuperative water flow rate. The available hot water flow for each connection size is as follows:

    ½" Diameter GPM = 0.33, 0.5, 0.67, 1.0, 1.33, or 1.67
    ¾" Diameter GPM = 2.0, 2.33, 2.67, 3.33, 4.0, 4.67, 5.33, or 6.0
    1" Diameter GPM = 6.67, 7.33, 8.0, 8.67, 9.33, 10.0, 10.67, 11.33, or 12.0
    1¼" Diameter GPM = 13.0, 13.33, 14.0, 14.67, 15.0, 16.0, 17.0, 18.0, 19.0, 20.0, 21.0, or 22.0
    1½" Diameter GPM = 24.0, 26.0, 28.0, 30.0, 32.0, 34.0, or 36.0

  3. The pressure available is the total pressure for two coils piped in series flow. The pressure available has been adjusted to account for a maximum of 100 equivalent feet of pipe at the maximum water flow rate for pipe and fittings external to the pump and valve assembly.

  4. Maximum Air Volume for Variable Air Volume (VAV) Systems is typically 70% greater than for Constant Air Volume (CAV) Systems.

  5. Motor electrical data is 120 volts, 60 Hertz, single phase for all sizes.

Available Pressure for Various Assembly Types: The different assembly types have different pressure available for the precooling and reheat water side pressure drop.

TRICOIL® Pump Package Selection Procedures

STEP 1 CALCULATE RECUPERATIVE WATER FLOW RATE, GPM.

The recuperative water flow rate is proportional to the supply air flow rate for the majority of applications. Use standard engineering cooling load calculations to determine the supply air volume required. For Constant Air Volume (CAV) systems, multiply the supply air volume times the conversion factor, 0.00216 GPM/CFM, to determine the required recuperative water flow rate. For Variable Air Volume (VAV) systems multiply the supply air volume by 0.7 (for part load selection) then multiple by 0.00216.

Example:

If the required air volume is 10,000 cfm the recuperative flow rate would be found using the following equation.

 

Supply Air Volume, CFM x 0.00216 =GPM (Recuperative Flow Rate)
 

10,000 CFM x 0.00216 GPM/CFM = 21.6 GPM

STEP 2 SELECT PUMP/VALVE ASSEMBLY SIZE.

To select the Pump Package size match the recuperative flow rate calculated in STEP 1, above, to the Flow Rate Column in the Selection Table. If there is no exact match use the next higher GPM value. Read the size of the Pump/Valve assembly next to the Available Flow Column. Select the actual flow in the recuperative loop by using note 1. Round off the recuperative flow rate to the closest value found in note 1.

Example:

The required recuperative flow rate calculated in STEP 1 is 21.6 GPM. Refer to Table 1: TRICOIL® Pump and Valve Assemblies above. In the column "Flow Rate, GPM" 21.6 GPM falls between 16 GPM and 22 GPM. The required Pump/Valve Assembly Size therefore is a size 22. Refer to note one of the table and use 22 gpm for the recuperative flow.

STEP 3 DETERMINE PRESSURE DROP AVAILABLE FOR COILS

The pressure drop available for precooling and reheat coils is indicated in the "Available Pressure" Column of Table 1 when Type A assemblies are used. Refer to Table 2 when type B thru type H are used.

STEP 4 SELECT HOT WATER FLOW RATE

The hot water flow rate can be as high as the recuperative water flow rate. Flow control valves are also used in the heating hot water circuit to automatically balance to the specified hot water flow rate. The available water pipe connection sizes are indicated in Table 1 and the available flow rates are indicated in note 2.
