HVACTEMPLATE:PLANT:TOWER

This object adds a cooling tower to an HVACTemplate:Plant:ChilledWaterLoop or MixedWaterLoop.

Name

Tower Type

Type: choice (SingleSpeed or TwoSpeed)

High Speed Nominal Capacity

Applicable for tower type SingleSpeed and TwoSpeed Nominal tower capacity with entering water at 35C (95F), leaving water at 29.44C (85F), entering air at 25.56C (78F) wet-bulb temperature and 35C (95F) dry-bulb temperature, with the tower fan operating at high speed. Design water flow rate assumed to be 5.382E-8 m3/s per watt(3 gpm/ton). Nominal tower capacity times (1.25) gives the actual tower heat rejection at these operating conditions.
Unit: W
Default: autosize

High Speed Fan Power

Applicable for tower type SingleSpeed and TwoSpeed
Unit: W
Default: autosize

Low Speed Nominal Capacity

Applicable only for Tower Type TwoSpeed Nominal tower capacity with entering water at 35C (95F), leaving water at 29.44C (85F), entering air at 25.56C (78F) wet-bulb temperature and 35C (95F) dry-bulb temperature, with the tower fan operating at low speed. Design water flow rate assumed to be 5.382E-8 m3/s per watt of tower high-speed nominal capacity (3 gpm/ton). Nominal tower capacity times (1.25) gives the actual tower heat rejection at these operating conditions.
Unit: W
Default: autosize

Low Speed Fan Power

Applicable only for Tower Type TwoSpeed
Unit: W
Default: autosize

Free Convection Capacity

Applicable for Tower Type SingleSpeed and TwoSpeed Tower capacity in free convection regime with entering water at 35C (95F), leaving water at 29.44C (85F), entering air at 25.56C (78F) wet-bulb temperature and 35C (95F) dry-bulb temperature. Design water flow rate assumed to be 5.382E-8 m3/s per watt of tower high-speed nominal capacity (3 gpm/ton). Tower free convection capacity times (1.25) gives the actual tower heat rejection at these operating conditions.
Unit: W
Minimum: 0.0
Default: autosize

Priority

Applicable for all Tower Types If Condenser Plant Operation Scheme Type=Default in HVACTemplate:Plant:ChilledWaterLoop, then equipment operates in Priority order, 1, 2, 3, etc.

Sizing Factor

Type: real number
Multiplies the autosized capacity and flow rates
Default: 1.0

Template Plant Loop Type

Type: choice (ChilledWater or MixedWater)
Specifies if this tower serves a template chilled water loop or mixed water loop If left blank, will serve a chilled water loop if present, or a mixed water loop (if no chilled water loop is present).
