OAK RIDGE — The city is investing in a new cooling system for the Oak Ridge Recreation Center at 1403 Oak Ridge Turnpike.

The recreation center includes a game room with pool tables and arcade games, as well a gym and an indoor pool. In a news release, city government described the new cooling technology as innovative and “designed to improve operational efficiency, lower electricity costs, and reduce carbon dioxide emissions for the facility while supporting the growth of a local clean-tech company.”

That company is Shift Thermal and its system stores energy in the form of ice, made during off-peak hours when power is cheapest and cleanest.

“During the hottest parts of the day, when electricity demand and costs are at their highest, the stored ice supplements the building’s air conditioning, which then improves performance and reduces the strain on the power grid,” Shift Thermal CTO Mitchell Ishmael said in the news release.

The company uses an immiscible working fluid to circulate through the system, eliminating traditional ice-storage heat exchangers. This design simplifies installation, increases efficiency, and lowers costs for large-scale cooling systems, the news release stated.
