SYNOPSIS

High performance chiller plant is becoming more and more popular in HVAC industry. To achieve it, the optimized chiller plant design in terms of  water flow rate and temperature plays an important role during design phase.
Low water flow concept  in chilled or/and condenser sides of chiller plant are recommended by ASHRAE Green Guide in order to improve total chiller plant performance.
This seminar will discuss how low water flow helps improve chiller plant efficiency and what are positive and negative impacts on plant performance.
Low flow could be designed in different ways with different water supply and return temperatures and would have different impacts on chilled water and condenser loops.  How to apply low flow properly in chiller plant and the  limitations will also be shared.
