Chilled Water - Facilities & Campus Services

The campus chilled water system consists of a campus distribution loop, 4 chiller plants housing 8 centrifugal chillers with a total of 6,800 cooling tons capacity. Our primary plants, South and North chiller plants, have been recently updated to a variable pumping system; North Chiller Plant was completely renewed in 2018. Chilled Water Meters - Facilities & Campus ServicesOct 22, 2019 · October 22, 2019. Metering and measuring energy consumption at the building level is an important part of any energy management process. The BPI 2 program has metering goals of metering all utilities at the building level for Electricity, Water, Chilled Water, and Steam. These building usage totals are compared to the Campus Total meters and a percent metered is calculated for each utility.

Chilled Water Plants Facilities and Campus Services

Chilled Water Plant 2 (CWP2) was constructed in 1973-74 to meet the cooling loads on the statutory campus and included one 2,000 ton Carrier model 19CB centrifugal chiller (Chiller-5). Another 2,000 ton Carrier model 19CB centrifugal chiller (Chiller-6) was added in 1984. Both use R-114 refrigerant and evaporative cooling towers for heat rejection.

Free Cooling The University of Chicago Facilities Services

The chilled water plants use two chilled water economizer heat exchangers to provide free cooling when outside air temperatures drop below 45F. Campus demand for chilled water exceeded the capacity of the chilled water economizer heat exchangers at the plants requiring the operation of additional lower efficiency chillers to augment capacity. Options for Designing Chilled Water Pumping Schemes - Mar 09, 2017 · Options for Designing Chilled Water Pumping Schemes. The system for delivering chilled water to end users has changed significantly since the introduction of central chilled water plants. Drivers of this change have included increased cooling demands, improvements in technology and requirements for more energy efficiency.

Bridge Controls - Facilities Services

A chilled water bridge system shall fall into one of two categories, depending on the kind of building loads that are served. The building category will be designated when the designer/engineer have reviewed the building loads with the Chilled Water Engineer/Director. These categories are:(1) critical loads, (2) non-critical loads.
