Optimized thermocline, best figure of merit
CiNQ uses stratified water method for Thermal Energy Storage. Natural stratification relies on buoyant force rather than physical barriers, such as walls, baffles, or membranes to maintain separation between warmer liquid in the top of a vessel and cooler liquid in the bottom.
Typically, the incoming water mixes with water in the tank to form a 0.3 to 0.9 m thick thermocline, which is a region with vertical temperature and density gradients.
The thermocline prevents further mixing of the water above it with that below it. The thermocline rises as recharging continues and subsequently falls during discharging.
The chilled water storage tank is naturally stratified, maintaining cold and warm water in the tank without a physical barrier.
A thermocline maintained by carefully designed custom diffusers keep the warm and cold water separate throughout the tank’s operation.
During off peak cooling mode, the tank collects excess chilled water from the chillers through the bottom diffuser (charging mode) and warm water is returned to the chiller through the top diffuser. TES Tank utilize the excess chiller capacity to charge itself.
During peak cooling mode, cold water from the TES Tank is directed to the cooling network through the bottom diffuser (discharging mode) and return water is collected through the top diffuser.
During discharging mode TES Tank will augment the chiller capacity to satisfy peak demand.
TES tanks have been in use for some time and is a cost efficient and proven method to reduce the plant capacity, operational and maintenance costs. Augmenting chiller capacity with TES enables cost effective and optimized peak load capacity management with minimum resources. TES also helps reduce dependency on power grid to address demand spike.
TES act like batteries, which makes it easier to address the fluctuations in energy demand. TES has the potential to charge and discharge the excess energy during low and high demands respectively.
TES can act as chilled water buffer for facilities that require backup cooling to act as redundancy
Mission critical systems require uninterrupted chilled water supply. TES will ensure continuous supply of chilled water during chiller system or power supply failures, switch over period.
Energy & Atmosphere being a significant consideration in LEED points, TES can also help your green building initiatives.
NC-v4 EAp2: Minimum Energy Performance
TES can help you to comply ASHRAE 90.1–2010 which is based on cost of energy savings.
NC-v4 EAc2: Optimize Energy Performance
Bridge the gap for cooling equipment efficiency and comply with ASHRAE 90.1–2010
NC-v4 EAc4: Demand response
Ensure a demand response program is ready by using TES and earn points for both new building and existing buildings. TES can help you establish a demand response program on your own in case the utility provider do not have a program.
CiNQ has been consistently delivering Thermal Energy Storage Tanks using chilled water storage for Data centers and District Cooling companies in UAE. More than 40 TES Tanks conceived and engineered by CiNQ are operational in the region. CiNQ delivers TES tanks turnkey. The inhouse engineering, design and fabrications capability with optimized construction practices, quality assurance and project management enable CiNQ to deliver the TES tanks, meeting stringent acceptance criteria, within schedule and cost, complying local regulations.
Stratified Thermal Storage Tanks are provided with internal flow distributors that enable flow to enter and leave the tank. Diffuser for each project is custom designed to enable low flow velocities, utilize the density difference, inertia, and buoyancy effects between hot and cold water to attain stratification. The diffuser performance is simulated and verified using Computational Fluid Analysis. The custom design and placement ensure maximum utilization of the tank volume thus extending the run time.
