Thermal storage tank for chilled water.

Predominantly two types of. Adaptable to almost any chilled water district cooling system. Rouleau roman ellis 7 july 2015 chilled water tes an alternative to static ice introduction to thermal energy storage thermal energy storage tes chilled water typical storage medium water specific heat of 1 btu lb f sensible technology achieves capacity through high specific heat of water requires about 10 66 ft 3 water per ton hour at 20 degrees delta t. For over 30 years dn tanks has designed and built prestressed concrete tanks for stratifying and storing chilled water for the thermal energy storage tes process.

Thermal energy storage tanks are specially insulated to prevent heat gain and are used as reservoirs in chilled water district cooling systems. When applied to contemporary chilled thermal storage technology cwt allow the user to time shift the electrical load of the system from the peak day periods to off peak night time periods. The chilled water stored in the thermal tank can be used to provide turbine cooling in facilities that use gas turbines like a gt power plant. Thermal energy storage tes thermal energy storage commercialized over 30 years ago thousands of installations throughout the gcc world and the u s.

A properly sized chilled water tank adds the necessary volume to buffer the cooling system and allows it to operate at peak efficiency. Araner s thermal storage tanks provide a tailor made solution in the fields of refrigeration cooling and heating. Chilled water tes concept tank. Thermex buffer and solar storage tanks are high quality long service life vessels for projects that have large volume hot water or chilled water systems.

A testiac configuration would add to the overall efficiency of the plant. Adding chiller capacity would have cost about 10 million while the tes system cost about 7 million and a 200 kw. The secret to these cooling solutions is the special internal diffuser system that allows chilled water to be stored in two separate compartments so it can be charged and discharged simultaneously. Thermal energy chilled water or hot water is produced during periods of off peak electrical demand or usage collected in a thermal energy storage tank then withdrawn and distributed to the facility during on peak periods.

Tiac helps increase turbine power output in facilities situated in areas with extreme ambient conditions. By producing chilled water in the evening and using it during daily peak hours there are several advantages. The stratified thermal energy storage tes tank is a widely proven technology that collects excess process thermal energy to be used during load peak hours.
