What size AC do I need? How many BTUs will be enough?
Room: Size: 5m×4m×2.93m(ceiling height), second floor, good thermal insulation (newly-built house), fully enclosed room with a very small walk-in closet.
Appliances: 4 led ceiling lights, a fan, and two lamps.
Windows: 2.2 m long, 3.1 m wide, facing Eastwards, double-glazed windows, with thermal curtains(soon hopefully).
Persons living: 2
