This how easy we can control Delta-T
as per your wish:
"You Wish, We Control"
Benefits:
* Achieve High Delta-T across Load & PHX.
* Allow indoor unit to absorb maximum cooling from limited chilled water
* Less pumping.
* Fewer number of chillers working.
* Optimize working chillers & improve efficiency.
* Less Cooling Towers working and connected condenser pumps.
* Improve Cooling Effect indoor.
* Control Humidity level
* More & More ...... Satisfied Occupants & Peace of mind.
* Reduce your Cost Per TR
Looking forward to Repeat the Same Success @ your Premises.

We like to take you today in a small journey to
test possible solutions step-by-step.
29. Agenda:
• Identify Possible Reasons for
Low Delta-T and quantify effect
of peak heating load?
• Design an automatic control
system that will higher Delta-T
• Fix the control system and
commission, also keep
monitoring the performance.
• Ensure system capacity to treat
dehumidification preciously
while trying to control high DT .
• Balance the comfort with
efficiency and energy saving.
• Suggest New Specifications
with connected Load.
