Chapter 4, Problem 4.26P

Using M-15 filter media and the requirement of 60 cfm per person of outdoor air for the case of a designated smoking area for 53 persons, design a filter and air-circulation system allowing the actual outdoor air rate to be reduced to 20 cfm per person. Assume outdoor and recirculated air are mixed before filtering and insignificant amounts of outdoor air contaminants are present. The filter media must have a gravimetric efficiency of 80 percent in the 0 5 × 10 3 mm particle size range. The filter pressure loss should not exceed 0.12 in. wg.

The sensible effectiveness of a heat recovery ventilator is 53.6%. The inlet temperature of fresh air is 35°C and relative humidity is 50%. The inlet temperature of exhaust air is 24°C and relative humidity is 60%. The mass flow rates of fresh air and exhaust air are 1.3 kg/s and 1.5 kg/s, respectively. Calculate the outlet fresh air temperature and estimate the energy saving ratio of adopting heat recovery ventilator.
Gaisano Mall uses an atmospheric cooling tower to provide cooling for the jacket water of a four-stroke 309 KW diesel generator. The cooling tower efficiency is 53% at a temperature of approach of 11 deg. C. if ambient air has a relative humidity of 60% and dry bulb temperature of 31 deg. C, determine the cooling water supplied to the diesel engine in liters/hour.
A space is to be maintained at 22C and 50% relative humidity. The sensible heat load is 100 kW, and the latent heat load is 15 kW. Outside air is at 38C DB and 25C WB temp. Air is supplied to the space at 13C. If all-outside air system (no recirculation) is to be implemented, determine: (a) the cooling capacity in tons; (b) capacity of supply air fan in cmh; and (c) the coil bypass factor.
