Subsurface ground temperature: implications for a district cooling system.

Author(s) : MCCABE R. E., BENDER J. J., POTTER K. R.

Type of article: Article

Summary

Utility engineers for a large district cooling system at one northern US university have relied on published subsurface ground temperature data and over the past 30 years have installed more than 15 miles (24 km) of directly buried uninsulated chilled water supply and return distribution piping. The utility engineers now estimate that during the summer cooling season, peak heat gains in the buried chilled water piping exceed 1,583 kilowatts and cause USD 100,000 in energy losses each year. The authors report on an investigation of the subject.
