Project Background
The City of Bryant Parks Department maintains a 14,650 Sq Ft Aquatic Center Natatorium at 6401 Boone Road that was constructed in 2009. Currently the Humidity and Air Temperature conditions within the area above the enclosed pools are maintained with a PoolPak Dehumidi?cation System. The System has been relatively unchanged until 2019 when compressors were replaced and an Air-Cooled Condenser was added to improve dehumidi?cation. The system has since experienced additional compressor, controls, and heat exchanger failure as the result of reaching an expected life of 15 years.
The Natatorium consists of a main pool that has a surface area of 4930 sq ft and is typically maintained at 82 degrees Fahrenheit and a therapy pool that has a surface area of 1513 sq ft and is typically maintained at 95 degrees Fahrenheit. The remaining wet deck surface area is approximately 2000 sq ft and the total volumetric capacity of the facility is 296,000 cubic feet. During Summer months excessive diurnal radiant heat from the transparent roof and wall system is compensated by opening roof panels.
