An air conditioned theater is to be maintained at 80°F dry bulb temperature and 50% RH (h = 31.35 Btu/lb). The calculated total sensible heat load in the theater is 620,000 Btu/hr, and the latent heat load is 210,000 Btu/hr. The air mixture at 84°F db and 72°F wb temperature (h = 35.82 Btu/lb) is cooled to 63°F dry bulb and 59°F wet bulb temperature (h = 25.78 Btu/lb) by chilled water cooling coils and delivered as supply air to the theater. Calculate the tons of refrigeration. a. 125* b. 130 c. 127 d. 122
