HW7P3 (15 pts) inters@buf A space in a building has a winter sensible heat loss of 180,000 kJ/h and a latent heat loss of Mben CDBT is to 60,000 kJ/h. The space is to be maintained precisely at 22C DBT and 50% RH. 50% by mass outdoor air at 0C DBT and 60% RH is required for ventilation. The amount of ventilation air is 100 cmm and the supply air is to be preheated, humidified with an adiabatic saturator to the desired humidity, and then reheated. The air temperature out of the adiabatic saturator is to be maintained at 15C dry bulb. Draw a schematic of the system, draw the cycle on the psychrometric chart, and determine the following: (a) The conditions of the air entering the space, (DBT & WBT). (b) The conditions of the air entering the preheat coil, (DBT & WBT). (c) The heat supplied to the preheat coil, kW (d) The heat supplied to the reheat coil, kW (e) The amount of makeup water required for dificationffalo.edu - Apr 12, 2023 HW7P3 (15 pts) inters@buf A space in a building has a winter sensible heat loss of 180,000 kJ/h and a latent heat loss of Mben CDBT is to 60,000 kJ/h.
