Design Concept of District Cooling
In district cooling, cooling energy in the form of chilled water is generated at a central chiller plant to be supplied via a piping network to multiple end-user buildings for the purpose of space or process cooling.
District cooling system are usually structured as infrastructure utility service but can also be end-user owned.
Economies of scale enable district cooling plants to adopt technology options such as
a) Thermal energy storage
b) Large capacity high efficiency chillers
c) Series-connected chiller modules
District Cooling Plant (DCP) :
A district cooling plant is an advanced cooling system that serves multiple buildings from a single, centralized location. Instead of each building relying on its own air conditioning unit, the district cooling plant produces chilled water and efficiently distributes it through a network of insulated pipes. This chilled water is used to cool the air inside the connected buildings, ensuring a comfortable indoor environment.
District cooling systems are highly energy-efficient, reduce carbon emissions, and offer significant cost savings compared to traditional cooling methods. By consolidating cooling resources into one plant, they minimize energy waste, lower maintenance costs, and support a more sustainable approach to building climate control.
Energy Transfer Station (ETS) :
The Energy Transfer Station (ETS) is a critical component of a district cooling system, serving as the interface between the central cooling plant and the individual buildings it serves. Located within each building, the ETS ensures precise cooling delivery by transferring energy from the chilled water in the distribution pipes to the building’s air conditioning system without mixing the two water systems.
The ETS also plays a vital role in metering cooling energy usage, ensuring contractual segregation, and maintaining hydraulic segregation, allowing each building to receive tailored cooling efficiently while seamlessly integrating with the district cooling network.
Thermal Energy Storage (TES) :
Thermal Energy Storage (TES) is an innovative and efficient solution within a district cooling system, designed to store cooling energy for later use. Instead of directly consuming electricity during peak hours, the TES system works by chilling water or producing ice during off-peak hours—typically at night when energy demand and costs are lower.
This stored cooling energy is then released during the day to meet the cooling needs of connected buildings. By balancing energy usage, TES reduces operating costs, lowers strain on the cooling plant during peak periods, and enhances the overall reliability and efficiency of the district cooling system. It’s a smart approach to sustainable and cost-effective cooling.
Distribution Piping :
The distribution piping network is a vital component of a district cooling system, acting as the backbone for delivering cooling to multiple buildings. These insulated pipes transport chilled water from the central cooling plant to the connected buildings, ensuring efficient and reliable cooling.
As the chilled water flows through the buildings, it absorbs heat and then returns through the same network to the cooling plant to be re-chilled. This continuous cycle ensures seamless operation, minimizes energy loss, and supports the overall efficiency of the district cooling system. The robust design of the distribution piping guarantees durability, safety, and consistent performance for long-term use.
The stored cooling energy is then discharged during the day to meet customer cooling load demand.
