Chilled water storage system design.

The return temperature is between 58 f to 60 f. Successful chw tes design strategies basis of design chilled water is normally stored at 39 f to 42 f in the storage tanks since this temperature range is directly compatible with conventional chillers. Designing chilled water systems typically used for cooling and dehumidifying a building s air chilled water chw systems circulate it throughout a building or campus complex. Select condenser water tempera tures flow rate and primary pipe sizes.

Description of chilled water system. Design of chilled water storage systems stratified storage tanks estimating tank geometry tall slender tanks are preferred to optimize thermocline and minimize footprint where practical tank height should be greater than highest air vent in chilled water lines prevents drainback quick formula for tank sizing. Components of a chilled water system. Volume gallons 5 875d 2h.

Select condenser water distribution. Coil control 3 way valves 2 way valves face and bypass dampers chiller plant design concepts parallel series and primary secondary or decoupled combined energy hybrid plants.

The university of north carolina at chapel hill owns maintains and operates a district cooling system comprised of 4 production plants and a thermal energy storage system distribution system consisting of over 26 miles of underground piping and building bridge systems consisting of over 150 bridges controlling chilled water in over 140 buildings or locations.
