Low Delta-T Rehabilitation Assessment & Execution Management
Rehabilitate your existing facilities & ensure that your current assets are functioning optimally & that you are getting your money’s worth
District cooling is a system that distributes cooling capacity in the form of chilled water or other medium from a central source to multiple buildings through a network of underground pipes for use in space & process cooling. It is an environmentally friendly, energy saving and economical cooling method. The cooling is centrally produced and distributed as cold water to each building through a closed distribution net.
-
9°C
minimum recommended chilled water temperature difference at the demand side
-
45%
increase in chiller plant energy consumption due to Low Delta-T Syndrome
What is Low Delta-T Syndrome?
Low Delta-T Syndrome is a condition whereby the temperature difference becomes lower than 9 Degrees Celsius, leading to disadvantages on the building and district cooling plant
Causes of Low Delta-T syndrome
-
Design
Improper selection of HVAC equipment and control valves -
Operation
Improper setpoints and operating procedures -
Maintenance
Faulty sensors, fouled heat exchangers, and lack of chemical dosing
Impact of low Delta-T on Buildings
-
Increase in Delta-T surcharges
-
Decrease comfort levels among tenants
-
Increase energy consumption by pumps

Control Delta-T management
Upon project completion, buildings shall witness considerable O&M costs, eliminated Delta-T surcharges, and improved comfort levels among tenants. Amongst other aspects, the following would be guaranteed benefits in dealing with the Low-Delta T Syndrome
Reduce Delta-T surcharges by 90-100% for buildings connected to District Cooling Plants
Immediate detection of faulty HVAC systems within the tenant spaces and take remedial actions
Provide 3rd party financing with risk-free performance-based repayment through shared savings
Improve comfort levels for occupants through a more balanced chilled water network
Ensure highest standards of equipment through data monitoring and healthy O&M practices
Reduce CO2 emissions through a lower chiller and pump consumption
