 The Process
In the VIM freezer, water is exposed to a deep vacuum. The vacuum causes a portion of the water to boil (evaporate) while the remaining water freezes, forming a water-ice mixture (ice slurry) at 0°C (32°F). The ice slurry is pumped from the freezer to an ice thermal energy storage (TES) tank. The water vapor is compressed by a centrifugal compressor and flows into a condenser where it is condensed, typically at about 10°C (50°F). IDE's VIM produces ice slurry, which is an ideal medium for TES and district cooling. The slurry contains 20% ice crystals, provides easy pumping (with small diameter pipes and very low pump energy), and has the flexibility for storage in any shaped storage tank.
A well-proven technology: VIM had been serving the refrigeration and mining industries since the mid-1990s.
A most efficient ice maker: Power consumption is typically only 0.85 kW/Ton.
A simple and low cost storage tank: The ice slurry is stored in empty tanks, with no moving parts.
Very rapid discharge capability: Rapid discharge maximizes flexibility for energy cost savings.
Environmentally friendly: VIM employs water as the primary refrigerant.
Six Ice Makers (850 Tons each) for mine cooling in South Africa, for Anglo Gold, operating since 1995, with three additional 850 Ton units to be installed during 2008.
One Ice Maker (100 Tons) for TES in Japan, for the Sanken Setsubi Kogyo Company, operating since 2002.
One Ice Maker (400 Tons) for TES in Japan, for the new NISSAN Technical Center, operating since 2007. For more information, please visit:
