The master's office in a ship is 4.6 m long by 3.2 m wide by 3 m high. One bulkhead and the overhead are exposed to the weather as shown in the figure. The bulkhead has one 54 cm by 87 cm window. The design occupancy is 4 persons and there are 4 80 W fluorescent lighting fixtures installed. The overall heat transfer coefficient for both the bulkhead and the overhead is 1.2 W/mK. Heat transfer through the other boundaries of the office can be neglected. Consider occupant and solar load. 30% outside air and (1-30%)% return air are mixed before entering air-conditioning unit. Then mixed air enters the air-conditioning unit. Estimate the cooling load of the office. Determine mixed air condition (dry bulb temperature and relative humidity ()) on Psychrometric Chart. Sketch the air conditioning unit with its components. When necessary, include a reheater in the HVAC unit. Show the air-conditioning process on Psychrometric Chart. Specify the dry-bulb temperature and relative humidity of the air delivered into the room by the air conditioning device. | Determine the capacity (in kW) of cooling section and reheater (if needed). Calculate the amount of dehumidified water vapor in kg/day. 3.2m Overhead exposed to weather 4.6m window 3 m 54cm office 87cm Troom 26C room %58 outside Toutside 31C bulkhead exposed to weather outside %64
