Systems that make ice during low-electricity-usage times, such as at night, then use the ice to cool the facility during the day.
Ice Energy - The Ice Bear is a low-cost energy-storage module that plugs into standard air conditioning systems. The storage module is charged at night when efficiency is at its peak. An ice storage air conditioner's ability to cool is not affected by hot temperatures the way a condensing unit is.
Trinity Thermal - IceCycle captures and stores inexpensive off-peak cooling energy and utilizes it to provide air conditioning during expensive on-peak periods. IceCycle works with the smaller air conditioning systems in homes and businesses and reduces air conditioning operating costs up to 20%.
CALMAC is the world leader in the product design and manufacture of Off-Peak Cooling (OPC) systems, which utilize Thermal Energy Storage (TES) to air-condition buildings. Ice is made at night in non-corrodible tanks and used the following day to cool the building.
CRYOGEL Ice Ball Thermal Storage - Energy is stored in Ice using low cost electricity at night to freeze Cryogel Ice Balls. Ice forms inside the Cryogel Ice Balls which are installed in large tanks. During the day when required for air conditioning or process cooling, this "cool energy" is released. [It would be more accurate to state that heat is removed from the building by being transferred to the "Ice Balls" which then slowly melt as they take in the heat energy. The human perception is that "coolness is released" into the room.]
Pure Energy Corp - Mechanical refrigeration is used to make ice, often at night when electric rates are lower. This ice is stored, and when cooling is needed in the daytime water is circulated through the ice storage media and then distributed at about 34F (1.7C) to provide space cooling.
Baltimore Aircoil - TSU-M, Ice Chiller® - Cooling with ice thermal storage can be the most cost-effective, reliable system approach to cooling offices, schools, hospitals, malls and other buildings, and provides a steady source of low temperature fluids for process cooling applications. These systems are environmentally friendly because they help lower energy consumption and reduce greenhouse gas emissions.
Dunham-Bush - Ice-Cel® is an ice thermal storage system that offers building owners and managers a simple and effective way to reduce electricity demand as well as energy usage charges. During off-peak energy demand hours, the chiller is operating to freeze water in the tank and thus to store the cooling effect. During peak energy demand hours, the chiller is shut down and the glycol is circulated to air handlers to provide air conditioning.
Santee Cooper - The thermal energy storage program enables commercial and industrial customers to shift the electrical demand for air conditioning to off-peak periods when the demand is low for electricity. This system makes ice or chills water at night (off-peak) and stores it for daytime cooling needs.
Airclima Research - Advanced ice thermal storage systems - The Ice Containers are spherical plastic capsules filled with water to freeze and which are especially designed not to expand during freezing.
VogtIce - TURBO is the world leader in ice harvesting Thermal Storage Systems and industrial chillers, each a recognized leader in its specialized field.
Integrated-Ice Systems - The benefits of commercial TES systems has been known for years. Now, those same benefits are available for residential as well as small commercial projects wishing to take advantage of Off-Peak power rates and ICE-X™ Technology
Swampy Cooling Systems - The 12-Volt portable "Ice Water" Model uses Ice to cool a liquid, which in turn is circulated through a Chiller (Heat Exchanger). Hot ambient air is passed through the Heat Exchanger to produce cold comfortable air-conditioned air, plus remove humidity!
Personal Ice Cooling Machine With Ionizer - Unlike a fan that blows hot air, the Personal ice cooling machine cooler can cool personal air space 15°F cooler when compared to a regular fan. The ice cooler is a cost effective alternative to the more expensive portable air conditioners. Great for the home or office.
System Relies on Ice to Chill Buildings - Some office towers have found a way to stay cool while keeping the AC to a minimum - by using an energy-saving system that relies on blocks of ice to pump chilly air through buildings. Water is frozen at night when power demands are low, and the cool air emanating from the ice cools the building during the day. (PhysOrg Jul. 15, 2007)
Honda uses ice-chiller to cool workers - The Japanese automaker makes ice at night and then melts it during the day to cool the 1 million-square-foot complex of buildings, where vehicles are designed. Payback expected in three years system expected to last 20 years. (PhysOrg July 18, 2006)
NVC cuts energy costs with cutting edge AC - Air conditioning will be out at Napa Valley College in coming years, and huge blocks of ice will be in. The method is called thermal energy storage. The compressors will run at night, when electricity is cheapest, turning the water into ice. During the day, water pipes will circulate ice water to the buildings. (Napa Valley Register September 30, 2005)
The Big Chill - Comfort Link, a downtown Baltimore company, daily produces some 6 million pounds of ice. "We build ice when the price of electricity is down". "We can store it and use it [to chill water] when the price for electricity might be four times as much." (Baltimore City Paper July 10, 2002)
Iraqi homes show US how to build - Ice-cooling was once widely used in western cities and societies. Now largely forgotten, it was first recorded as a coolant more than 4000 years ago. In northern Iraq, Kurdish communities widely used, and continue to use, natural ice. The ice is stored in pits for use in summer. (Aljazeera.Net February 04, 2005)
