13.72 SECTION THIRTEEN<br />

Thus, for 80�F DB, 50% RH, <strong>and</strong> dew point at 59�F, the minimum discharge air<br />

temperature would be 62�F as insurance against sweating. The amount of air to be<br />

h<strong>and</strong>led may be obtained from Eq. (13.30), with a temperature difference of 18�F.<br />

13.23 CONDENSERS<br />

If a water-cooled condenser is employed to remove heat from the refrigerant, a<br />

water tower (Fig. 13.31) may be used to cool the condenser discharge water, which<br />

can then be recirculated back to the condenser.<br />

Where practical, the water condenser <strong>and</strong> tower can be replaced by an evaporative<br />

condenser as in Fig. 13.32.<br />

system.<br />
