2.1 MANUFACTURERS
A. Basis-of-Design Product: Subject to compliance with requirements, provide product indicated on
Drawings or comparable product by one of the following:
1. PoolPak
2. Four Seasons
3. Munters/Des Champs
2.2 PRINCIPLE OF OPERATION
A. The unit shall control space temperature and relative humidity and pool water temperature.
Warm moist air from the natatorium is drawn over an evaporator, and the latent and sensible
heat is removed from the air. The heat captured by this process and the heat generated from the
compressor power consumption are absorbed by a mechanical refrigeration system. The
resulting dryer, cooler air is drawn over a reheat condenser coil and auxiliary heating coil (if
provided) by a supply fan.
B. The refrigeration system is activated if any of the following occur:
1. Relative humidity rises above set point.
2. Space temperature rises above the set point.
C. The unit shall monitor space temperature and relative humidity, pool water temperature and
building surface temperature.
1. The thermal energy absorbed by the refrigeration system is distributed as follows:
