Consider a room with infiltration or exfiltration though a windward wall, a leeward wall and a ventilation pipe on the ceiling. A window of the same type is located on each wall and walls are impenetrable. Each window has a crack length of 2 m, with K=6. The ventilation pipe has a diameter of 5 mm. The pressure differences for windward wall, leeward wall, and ceiling are 25, -25, and -2.0 Pa, respectively. Indoor air is of 24C (RH=50%) and outdoor air is 30C (RH=50%). (a) Estimate the volumetric flow rate via infiltration or exfiltration through each window and ventilation pipe, respectively; (b) What is the cooling load due to the combined infiltration and exfiltration of the three? (c) Do you have a net gain or loss of moisture? At what rate?
