March of Passion to provide innovative energy efficient solution Continues with :
• Ice on Coil Thermal Energy Storage and Stratified Chilled Water Thermal storage,
• Non Barrier Centrifugal Separators and Filtration Solutions,
• Chemical Free Cooling Tower Water treatment,
• State of art modern Expansion Tanks & Pressurization unit with built in de-aerator
• Air Purification & Disinfection System.
Working
• Thermal Energy (chilled water) is produced during
periods of off-peak electrical demand or (usually at
night) or simultaneously with ongoing operation
• It is collected in a thermal energy storage tank and
withdrawn and distributed through the facility
during peak rate/demand hours.
• Warm and chilled water enters and exits the tank
through diffusers located at the top and bottom of
the tank. These diffusers are designed to eliminate
turbulence and provide a stable, sharply defined
transition layer, or “Thermocline”,* thus allowing
for the natural stratification of warm water at the
top of the tank and chilled water at the bottom.
• Density and Kinematic Viscosity plays a significant
role in designing the CHWTES and successful
stratification.
Working
• Ice Creation During Off-Peak Hours: During periods of low electricity demand (off- peak hours), typically at night, the chiller system operates to freeze water into ice within the storage
• Energy Storage: The ice storage tank stores thermal energy in the form of ice. This ice serves as a thermal battery, storing cooling potential for use during peak demand
• Cooling During Peak Hours: During high electricity demand periods (peak hours), the stored ice is used to provide cooling. The chiller can be turned off or run at a reduced capacity, as the melting ice supplies the necessary
• Heat Exchange: Warm water from the building’s cooling system is circulated through the ice storage tank, where it is cooled by the ice. This chilled water is then recirculated through the building’s air conditioning
•Energy Efficiency: By shifting the production of cooling to off-peak times, the system takes advantage of lower electricity rates and reduces the load on the power grid during peak
•System Integration: The thermal ice storage system is integrated with the building’s HVAC (heating, ventilation, and air conditioning) system, ensuring seamless switching between ice-based cooling and conventional chiller
•Control System: Advanced control systems manage the chiller and ice storage operations, optimizing the timing of ice production and melting to maximize efficiency and cost
•Environmental Benefits: Reduces peak electrical demand, leading to lower greenhouse gas emissions if the electricity comes from fossil fuel sources, and contributes to a more stable and efficient power
