Natatorium DesigN maNual
dehumidified and reheated air to the space, and warm
water to the pool. Not a single BTU on either side of the
refrigeration cycle is wasted. COPs are close to 8 and
EERs greater than 25!
Figure 3 illustrates schematically how warm humid air
passes through the dehumidifying coil and is cooled to
below its dew point. Once air is cooled below its dew
point, moisture condenses out of the air. Depending on
the space temperature requirements the hot gas from
the compressor can be used to reheat the air or be
rejected to an outdoor condenser. Compressor hot gas
can also be used to heat the pool water.
Refrigerant Reduction:
Seresco’s NP Protocol Series
The “Protocol” NP Series is fast becoming the HVAC
industry’s new benchmark for indoor swimming pool
dehumidifier technology. You get everything you like from
an all DX unit while further reducing annual operating
costs by 5-7% and reducing the system refrigerant
charge up to a whopping 85%!
Named after the 1997 Kyoto Protocol environmental
treaty that triggered the elimination of environmentally
hazardous refrigerants, Seresco’s Protocol Series
substitutes hundreds of pounds of refrigerant with
