DECATUR, GA.—Seresco USA Inc., a leading manufacturer of HVAC indoor air quality equipment, has introduced the “Protocol” (NP) Series, new indoor swimming pool dehumidifier technology that reduces refrigerant use by up to 85 percent and is more efficient than conventional DX dehumidifiers.
The NP-Series ranges from 18 to 140-ton units that provide energy-efficient natatorium space heating/cooling and optimum humidity control, while also offering free pool water heating and reheat through heat recovery.
Named for the 1997 Kyoto Protocol environmental treaty, the Protocol Series substitutes hundreds of pounds of vapor compression refrigerants commonly used in traditional natatorium dehumidifiers with glycol that’s 95 percent less expensive and an environmentally-preferred heat transfer fluid for LEED and other sustainable building projects. The Protocol Series’ heat exchangers transfer refrigerant heat to glycol for either free supply air reheat or heat rejection to dry coolers. The result is more system reliability, reduced refrigerant leak potential, longer compressor life and significantly reduced project costs, because external PVC glycol piping to dry coolers is less expensive to install in labor/materials than copper refrigerant piping to condensers.
Seresco’s proprietary heat rejection design makes the Protocol Series equally efficient as DX systems on summer design days and 5 to 7 percent more efficient throughout the rest of the year. The innovative design uses an active refrigeration head pressure monitor/control that ensures the lowest possible condensing pressures to boost system performance. Maintenance-free direct drive blowers with variable frequency drives (VFD), that are standard in all Seresco equipment, also provide additional operational efficiencies.
Additional efficiency is offered with optional heat recovery from exhaust air.
