h. Closets and Storage Areas in Air-Conditioned Facilities. These areas should be either
directly air conditioned or provided with exhausts to transfer conditioned air from adjacent
spaces.
i. Reheat. Where reheat is required to maintain indoor relative humidity below 60 percent,
consider heat recovery, such as reclamation of condenser, heat in life cycle cost analysis.
j. Economizer Cycle. Economizer cycles generally will not be used due to the high
moisture content of outside air.
k. Penetrations of Conditioned Envelope and Thermal Bridging. Considerable moisture
may enter the conditioned envelope both through penetrations for items such as pipes and
conduits or as condensation as a result of thermal bridging at locations such as door and
window frames and intersections of walls or walls and roofs. Provide details on the drawings for
penetrations and potential thermal bridges.
2-15. WATER TREATMENT. The local water composition is essential to the design of water
treatment for mechanical systems. A water analysis may be available from the using agency. If
an analysis is unavailable, obtain a sample of the raw water. Test the sample and include the
results in the applicable contract specifications. Design water treatment systems for boilers in
accordance with TM 5-650. Provide water treatment systems for cooling towers for prevention
of corrosion, scale, and biological formations. In most cases, a water treatment is required for
closed chilled-water systems, hot water systems, and dual-temperature systems.
