Seresco USA Inc., a leading manufacturer of HVAC indoor air quality equipment, has introduced the Protocol (NP) Series, the HVAC industry’s new indoor swimming pool dehumidifier technology that reduces refrigerant by up to 85 percent and is more efficient than conventional DX dehumidifiers, the company says.
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.
The Protocol Series substitutes hundreds of pounds of vapor compression refrigerants commonly used in traditional natatorium dehumidifiers with glycol that is 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. Seresco says 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.
