Lamar Consildated ISD recently constructed their first natatorium, and required an air conditioning system that could control the high levels of humidity generated by the pool to create a comfortable environment with good air quality for swimmers and spectators at a reasonable cost. HTS was chosen as basis of design based on previous success with other natatorium projects, and HTS equipment was selected because it met necessary specifications while remaining cost efficient.
HTS worked with PBK, Waller County Mechanical, and natatorium equipment specialist Seresco to select a system that would alleviate the pool conditions in the space, as well as the outdoor corrosive air conditions of Houston. Seresco equipment is designed specifically for natatorium use, and includes a protective coating for chlorine air and a Protocol system, which allows the indoor and outdoor units to be located far apart.
The system included two Seresco Indoor Dehumidifiers and two Seresco Outdoor Air Handling Units totaling 58,000 CFM. These pieces of equipment accommodated a unique combination of DX split systems with reheat and are designed to be compact and efficient, while preventing issues with oil return in the DX system and decreasing the required refrigerant charge. Seresco equipment is also accompanied by WebSentry, which provides factory support and allows the equipment to be monitored remotely.
A 4,600 CFM United Cool Air Outdoor Air Handling Unit was included, which can alternate between using 100 percent outside air and 100 percent recirculated air, while providing tight control to the spectator area of the natatorium. A 34 ton Daikin VRV unit was also installed to deliver energy efficient, quiet air conditioning to the offices in the building.
HTS was able to overcome challenges with coordinating assembly and meeting space limitations, as well as maintaining the aesthetics of the facility by placing condensing units and line runs out of view.
