Thermal Energy Storage

Thermal Energy Storage

Equipment Replacement:

Current Vogt HP / FTS / ATS equipment has been used to replace Avalanche Ice Harvesting systems and Ice Master Harvesting TES systems. In most cases, the existing storage tank can be retained. Vogt Thermal Energy Storage Equipment can be modified to utilize an existing tank and chilled water distribution system preventing costly system overhaul.

Upgrading In Place Equipment:

Existing HP and IGC equipment can be upgraded with an increase in efficiency and improvement in reliability.

Among the Areas of Upgrading:

  • Flat bottom water pans – replace the ‘V’ notch pans and offer a more even flow of water onto the active area of the plates.
  • Corrosion resistant defrost valves – Revised Thermal Expansion Valve piping lengthens life of the TEV and increases performance.
  • Control system – allows for remote monitoring and control of your ice harvesting thermal storage system.
  • Refrigerant changeover – with the phase out of R22, Vogt can recommend and facilitate requirements for upgrading your system.
  • Plate upgrades – The HP system can now incorporate a deeper plate that can fit in the same frame. Capacity increases can be realized of up to 20% while extending the useful life of the unit.

Use: Use off peak or low load periods to build cooling reserves to be used for industrial or comfort cooling applications.

Solutions: Turbo HP / ATS / FTS product lines and Vogt Tube Ice TS series products.

Applications:

Unlike other thermal storage systems, the ice harvesting design uses an ice-making surface that is completely separate from the ice storage tank. The ice-making surface consists of stainless steel plates that are welded together to form computer-designed internal channels for controlled flow of refrigerant or stainless steel tubes integrated into a shell and tube heat exchanger. In the plate harvester, water is distributed uniformly over the outside of the plates. The plates are grouped vertically in modules directly above the ice storage tank. Ice forms on both sides in sheets 1/4″ inch thick. Then, at predetermined intervals, hot refrigerant enters the plates, causing the ice to break away and drop into the tank. The ice breaks into small pieces in the tank.

The Tube Ice design operates much the same way. Water is circulated to a tank above the stainless steel tubes and flows down each tube forming ice the length of the tube. At the optimal thickness, warm refrigerant enters the vessel and the ice releases from the tubes and drops into a storage tank. The harvest process causes the ice to break into much smaller pieces allowing for better heat transfer characteristics when the load occurs.

The cycles are repeated as long as there is need for additional cooling reserves. Fragmented ice gives a tremendous amount of heat transfer area, allowing very rapid melting with no risk of short circuiting of the return chilled water.

This continuous ice making capability is impossible with systems where heat transfer coils are submerged in ice storage tanks-because the ice making surfaces become encased in ice, insulating the heat transfer surface and reducing the efficiency of the system, while waiting for a thaw before production can resume.

Features:

  • Infinite available surface area of ice for quick release of cooling to the load
  • The ice harvester acts as an efficient chiller when not making ice

  • The heat transfer surface and associated refrigerant piping is easy to access

  • Low temperature water (33 deg F) can be generated for economical water distribution (pumps, piping) to the cooling load.

Typical applications

  • Chemical processes requiring jacket cooling

  • Dehydration processes

  • Dairy- Pastuerization and blow molding processes

  • Clean room air conditioning

  • District Cooling (airports, hotels, business centers)

  • Inlet air cooling for combustion turbines

THE FLEXIBILITY OF PROVEN EQUIPMENT

TURBO has been manufacturing ice handling products since 1967, applying ice making technology and solving ice storage and handling problems for all these years. The products demonstrated here incorporate functionally interrelated features, designed to deliver extended, dependable performance with minimum maintenance. Flexibility built-in to store and discharge any kind of ice: flake, tube, plate, or shell.

RODUCT QUALITY – The use of one or more ice rakes allows theice to “cure”. Ice delivered to a rake in a below freezing room can have residual moisture removed. The dryer (and colder) the ice, the easier to handle. Dry ice .ows better, bridges less and does not experience problems found with handling wet ice.

STORAGE VOLUME – Maximize the ice maker’s volume by providing ample storage space. Tons of ice can be stored over a period of time and delivered from the rake bin in a short period of time to meet high demands.

REDUCED ENERGY COSTS – Cheaper off-peak energy can be used to run the ice makers while the ice rakes are filled.  During the on-peak time, the ice makers can sit idle while ice is available from the ice bin.  This type of electrical load shifting can mean large savings to plant operators.

Rakes Technical Data

EXCLUSIVE LOAD DETECTOR

TURBO has anticipated many user’s problems. A special load detector device signals the rake assembly to raise automatically according to varying rates of ice build-up in the bin. Also, it may be adjusted for different ice delivery rates. There is less strain and wear on the working equipment; less chance of breakdown; and, most important, less chance to bury the rake.

THE IMPORTANCE OF COMPONENT COATINGS

Another innovative concept. Ice and water can rust equipment, a known fact to everyone in this business. TURBO protects the vital components. To minimize rust and corrosion, all chains, sprockets and other steel components are eletro-coated or hot dip galvanized to produce a minimum maintenance finished product. Storage bin sliding is aluminum to keep the product clean and pure. The option of stainless steel also can be specified.

A VARIETY OF APPLICATIONS

The built-in flexibility of these products makes this equipment an efficient answer to ice storage for many practical applications.

  • PACKAGED ICE
  • INDUSTRIAL MARKETS ( Chemical processing, Seafood and Poultry Processing )
  • AGRICULTURAL ICING ( Produce )
  • CONSTRUCTION ( Concrete Icing )

All TURBO ice storage products are USDA approved(installation onsite inspection may be required). Built to meet most industrial standards. Ice loading and unloading is safe and simple. Regardless of size, every TURBO ice rake operates on basically the same, simple manner. Whatever the job, TURBO can match ice storage and delivery to demand.

GETTING THE MOST OUT OF YOUR STORAGE

Bottom ice (blue ice) left for sometime will compact and solidify. This puts a great demand on the rake assembly to get this ice out. Turbo’s rake is better equipped to do this.

This is accomplished by furnishing a much more sturdy rake assembly to handle blue ice efficiently. Turbo’s heavier-duty rake can dig deeper into older, more compact ice. Our engineers with their combined experience came up with the answer. Just build a more rugged rake than the competition. Much heavier steel components do the job.

LESS DOWNTIME

This is the real user benefit. A more rugged constructed product that’s more corrosion and rust resistance will always result in a product operating with less wear, less chance of breakdown. And that’s what users need. Turbo’s flexibility of design with the many options matches ice storing and delivery to demand, matches the product to the working conditions. As the respected leader in this business, experience has taught us what users need and want. Hundreds of applications in almost all types of storage/handling locations have helped us to anticipate any problems that can occur, BEFORE any product is installed.

~3 Overall height ‘H’ is determined by adding 5′-3″ to the ice height. Ice heights are available in one foot increments from 8 feet to 18 feet. Desired ice capacity (U.S. tons) divided by tons/ft. (above) equals ice height rounded to the nearest foot. Ideal ice height is 12 feet. Example: For a 20′ * 45′ rake with 210 U.S. desired tons storage capacity

Ice height = 210 U.S tons / 18.0 tons/ft = 11.67ft.

Specify 12 feet ice height. Actual storage capacity=216.0 U.S. tons
