QUESTION 1 Determine the cooling load caused by NE and NW walls at 21 hr. The walls' dimensions are (3.5m x 3.3m) each. The outside design conditions: maximum temperature of 38°C and minimum of 25°C. The inside design day bulb temperature is 23.0°C. Assume: NE wall No. 11 and NW wall No. 13. U-value for each wall is = 0.35 W/m2K. QUESTION 2 Determine the total cooling load caused by two windows of a building at 13hr. The first glass is facing West while the second is facing East. The outside design conditions: maximum temperature of 42°C and minimum of 27°C. The inside design dry bulb temperature is 25.5°C. Assume: The room configuration is of zone C. Each window has the following data: U - 5.0 W/m2K. dimensions (3.8m x 3.7m), and SC-0.34. QUESTION 3 Estimate the cooling load in a building at 15 hr and 22 hr from 159 athletics people in a Gymnasium occupied from 0700 h to 1300 h and 74 walking (4.8 km/hr) people occupied from 1400 h to 1800 h. The Gymnasium temperature is 25°C, and the cooling system operates continuously. Assume the conditions of the space define as Type D.
