Available provision profile
Available processing profile allows selection of a profile from the database to define the availability of the Cooling Tower due to manual operation. If a schedule is not required, the profile should be defined as “on continuously”.
Electricity consumption metered
The Electricity consumption metered option allows the user to determine whether the electricity consumption of the Cooling Generator should be considered as part of the network. If the box is checked (the condition is true), it is assumed that the electricity consumed by the Cooling Generator has already been included in a general electricity demand meter.
Cooling system type
The cooling tower cooling system for this cooling tower installation
COC
Cycles of concentration determines the amount of make-up water required to replace blowdown water. Typical values for cooling towers are between 3 and 10.
COP curve
A COP curve defines the coefficient of performance of the Cooling tower as a function of the Capacity. Capacity values should be entered as a proportion of the maximum capacity. A COP Curve Editor is accessed by double clicking on the COP curve input value, then selecting the edit button that appears in the field.
Design ambient air wet bulb temperature
The design ambient air wet bulb temperature used for operating the cooling tower. It is typically set to a value which is typical for the geographical region where the cooling tower is located.
Design Approach
The temperature difference between the design ambient air wet bulb temperature and the outlet water.
Design fan power consumption
The power consumption of the fan at design conditions.
Design heat rejection input
Design heat rejection input allows the user to define the maximum amount of waste heat that the cooling tower can process. If the Waste Heat exceeds the Maximum input, the Waste Heat value not addressed by the Cooling Tower is calculated by the energy manager.
Design pump power consumption
The power consumption of the pump at design conditions
Design range
The difference in temperature between the inlet water and outlet water at design conditions
Windage drift factor
Windage drift fraction is the fraction of heat lost from the cooling tower circulating water due to windage drift; mechanical transport of water into the air-stream by the fan. Typical values are from 0 to 0.003 depending on the type of cooling tower whether or not the cooling tower has drift eliminators installed.
