Thermal Storage Tank For Chilled Water

Tiac helps increase turbine power output in facilities situated in areas with extreme ambient conditions.

Thermal storage tank for chilled water.

Chilled water system example application needing an additional 3 750 tons of peak cooling capacity for a 250 000 square foot addition to its dallas hea d quarters texas instruments chose a chilled water thermal storage system. Warm and chilled water enters and exits the tank through diffusers located at the top and bottom of the tank. Predominantly two types of. Adaptable to almost any chilled water district cooling system.

Every single one of these tanks is watertight and still operational today. 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. 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water is produced during periods of off peak electrical demand or usage collected in a thermal energy storage tank then withdrawn and distributed to the facility during on peak periods. 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.

Adding chiller capacity would have cost about 10 million while the tes system cost about 7 million and a 200 kw. By producing chilled water in the evening and using it during daily peak hours there are several advantages. Thermal energy storage tanks are specially insulated to prevent heat gain and are used as reservoirs in chilled water district cooling systems. Chilled water tes concept tank.

These mild steel vessels can be used as storage or buffers tanks for hot water or chilled water to increase thermal inertia thereby reducing system cycling and in the case of dhw increasing. Thermal energy storage tes thermal energy storage commercialized over 30 years ago thousands of installations throughout the gcc world and the u s. 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. 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.

A properly sized chilled water tank adds the necessary volume to buffer the cooling system and allows it to operate at peak efficiency. 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 stratified thermal energy storage tes tank is a widely proven technology that collects excess process thermal energy to be used during load peak hours.
